invariant-stewardship
by tkerseyUse before local patching when bugs, regressions, malformed state, crashes, parser failures, migrations, cache drift, protocol problems, compatibility requests, tolerant readers, fallbacks, coercions, retries, catch-and-continue logic, or local workarounds may broaden accepted invalid state.
ms
by tkerseyCreate, update, or refactor Codex skills in this repo: SKILL.md, frontmatter triggers, agents/openai.yaml, scripts, references, and assets. Use for creating a skill or direct in-place skill edits now; not for read-only analysis or "should we update this?" turns. Treat `$refine` as higher-level evidence-driven existing-skill refinement.
creative-problem-solver
by tkerseyLateral-thinking playbook returning a five-tier strategy portfolio (Quick Win through Moonshot) with a default-basin check. Use for options, alternatives, trade-offs, stalled/repeated failures, creative reframing, or strategic path selection before execution.
adversarial-reviewer
by tkerseyChallenge non-trivial code artifacts with authority-gated adversarial review. Surface only material, current, owned, witness-backed findings; separate candidate concern validity from material-finding eligibility; require no-finding countercases, soundness rows, authority clearance, verification paths, and change-agenda consistency before emitting a remediation agenda. Trigger for exhaustive review, fresh-eyes second pass, re-review after fixes, patch hardening, full-scope de novo challenge, or material fixed-point review. Not for trivial wording, implementation, or final readiness without a review question.
shadow
by tkerseyGoal-native session shadowing: watch exactly one Codex session through `$seq`, apply one named target-skill lens, emit a compact cycle result, and avoid repeated full analysis when evidence has not changed. Use for `$shadow`, shadow/tail/watch/follow/monitor/supervise one session, `$shadow $tune`, goal-cycle monitoring, target-skill evidence delta, partial activation, status-only-stop, or proposal handoff. Do not use for broad session mining, autonomous scans, raw transcript inspection, editing without apply mode, or creating a second continual controller outside `/goal`.
cybernetic
by tkerseyUltimate systems-thinking and feedback-control skill. Use for `$cybernetic`, systems thinking, cybernetics, complex adaptive systems, root-cause vs structure, feedback loops, stocks and flows, leverage points, incentives, delayed effects, unintended consequences, DART diagnosis, clear/complicated/complex/chaotic system classification, intervention design, policy design, organizational dynamics, product/business/ecosystem diagnosis, workflow loops, same-cluster review recurrence, and avoiding local optimizations that harm the whole. Produces cybernetic_context or a cybernetic_packet; read-only unless explicitly routed to another implementation skill.
zig
by tkerseyUse for implementing, reviewing, migrating, zig fmt steering, linting, testing, fuzzing, profiling, optimizing, or hardening Zig 0.16.0 code, including hazardous-code/Illegal Behavior audits: .zig, build.zig/build.zig.zon, std.Io/process.Init migration, C interop, comptime/reflection/codegen, allocator ownership, FFI, concurrency, safety-disabled scopes, raw pointers/layout/ABI hazards, dependencies, cache hygiene/disk pressure, and measured performance.
fresh-eyes-blunder-pass
by tkerseyRun a targeted fresh-eyes blunder pass over code, specs, plans, adjudications, closure gates, skill edits, or negative-evidence ledgers. Trigger when asked to reread with fresh eyes, find obvious bugs, catch mistakes/oversights/omissions, check for embarrassing misses, or perform a second independent blunder pass before closure. Do not use as a substitute for implementation, adjudication, or verification; use it as the final falsification/check pass for those workflows.
liminal
by tkerseyUse when delimited continuations or defunctionalization are central: shift/reset, prompt/control, prompts, subcontinuations, effect handlers as control operators, CPS translations, answer-type modification, abstract machines, first-orderizing higher-order interpreters, continuation runtimes, or source-backed study/research roadmaps. Do not use for ordinary async/await, generators, monads, compiler optimization, PL theory, or functional-programming questions unless delimited control, continuations, CPS/control translation, or defunctionalization is explicit.

Explore the agent skills ecosystem by occupation and creator
SkillMD is not just a keyword search box. It is an open map that organizes public skills by occupation, creator, and repository, helping you see which workflows, judgment criteria, and domain habits people are writing for AI agents.
Then follow creators and GitHub repositories back to the source: compare the skills a team maintains, whether the repo is active, and how the README frames the work before you open, install, or reuse anything.
Use it three ways: learn an unfamiliar field by occupation, study how creators organize skills, then use source context to decide what is worth opening or reusing.
01 Map a field
Browse 23 occupation groups and 867 SOC roles to learn what skills exist in adjacent domains and how they break down real work.
02 Follow creators
Use creator and repository pages to inspect maintained skill collections, recent updates, and source context before trusting a result.
03 Search with sources
Search 1.7M+ collected skills, then use occupation tags, creators, and GitHub source context to decide what is worth opening.
Start with the occupation map, then follow creators and repositories back to real code. SkillMD helps explain why a skill is worth opening, not only what it is named.
Standardizing Agent Capabilities with SKILL.md and Model Context Protocol (MCP)
In the rapidly evolving landscape of artificial intelligence, LLM agents (Large Language Model agents) have transitioned from simple text predictors to autonomous problem solvers. To orchestrate complex, multi-step agentic workflows, developers require a standardized format to specify agent capabilities, prompt instructions, system rules, and database bindings. This is where SKILL.md and the Model Context Protocol (MCP) have emerged as standard developer paradigms. SkillMD serves as the central directory for indexing, exploring, and sharing these critical agent configurations.
Our open-source registry currently tracks over 1.7 million collected SKILL.md configurations and system prompts. By compiling agent configurations from active developers on GitHub, we bridge the gap between prompt engineering research and production execution. Whether you are building agents with Anthropic's Claude Code, OpenAI's GPT-4, Google's Gemini, or local models using Ollama and LlamaIndex, standardized skill definitions ensure your agents behave predictably across different runtime environments.
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open-source standard designed to connect LLMs to data sources, developer tools, and external environments. MCP establishes a bidirectional communication channel between client applications (like Cursor, Claude Desktop, or custom agent systems) and servers hosting data or capabilities. Standardizing instructions via SKILL.md enables LLMs to query databases, read local files, execute terminal commands, and integrate third-party APIs. SkillMD allows you to find ready-to-run MCP servers and prompt instructions for various occupations and technical tasks.
The Structure of a Professional SKILL.md File
A valid SKILL.md configuration is designed to be easily read by humans and parsed by LLMs. It contains precise system instructions, trigger conditions, required parameters, and execution examples. Below is the typical architectural blueprint of a professional agent skill:
- Metadata & Core Scope: Declares the name of the skill, author details, target models, and a description of the capability.
- Triggers & Intent Detection: Details semantic triggers that help the agent decide when to invoke this skill.
- System Prompts: Explicit system-level instructions that direct the agent's behavior, personality, safety guardrails, and formatting preferences.
- Capabilities & Tools: Lists the files, databases, or APIs the agent must access to complete the tasks.
- Few-Shot Examples: Demonstrates real inputs and outputs, helping the model generalize behavior through in-context learning.
Optimizing Agent Workflows for Modern LLMs
Writing effective agent skills requires deep knowledge of prompt engineering. With the release of advanced reasoning models like Claude 3.5 Sonnet, ChatGPT o1, and DeepSeek-V3, prompt templates must focus on structured thinking. Developers are encouraged to use XML tags (e.g., <thought>, <context>, and <rules>) to isolate execution boundaries. Standardized prompts prevent agents from suffering from context drift, ensuring that long-running tasks remain aligned with the initial system parameters.
Exploring by SOC Occupations and Creator Profiles
What makes SkillMD unique is its taxonomy. Instead of simple text search, we parse and organize files according to the Standard Occupational Classification (SOC) system. This means you can discover skills written for Computer and Mathematical roles, Business and Financial operations, Legal, Design, and and Educational Instruction fields. By tracking creator profiles, developers can study how different teams organize their custom instructions, compare version updates, and fork public configs for specialized enterprise use cases.
SkillMD operates as a high-performance index running on a fast Go backend and a highly responsive Astro SSR frontend. All search queries execute in milliseconds, featuring smart debouncing to prevent multiple API requests while keeping user data secure.
