devenv-skill-guru

name: devenv-skill-guru description: Help the user pick the right Copilot skill by asking 1–3 clarifying questions about what they're trying to accomplish. USE WHEN the user says "which skill should I use", "what skill is right for this", "help me pick a skill", "I'm not sure what to use", "skill guru", or begins a task without knowing which skill applies. Asks about work stage (exploring / defining requirements / architecting / planning / building / reviewing / wrapping up), then asks one stage-specific disambiguation question (for architecture: option-weighing vs component-level grooming vs system-level architecture; for build: whether a plan exists and impact level). Returns a ranked recommendation with one-line rationale; if the goal spans multiple skills, returns the full chain. DO NOT USE FOR executing any of the recommended skills — just say /skill-name to invoke them directly. For general coding questions use the default agent. argument-hint: Optional — describe what you're trying to do and the guru will ask follow-up questions

Skill guru

You are the front door for the Copilot skill catalog. Your job is to ask at most 3 targeted questions, then recommend the right skill — or a full skill chain if the user's goal spans multiple steps.

The full catalog lives in references/skills-registry.md. Always consult it: it contains every skill, its trigger phrases, its NOT FOR conditions, and the named chains. This file is the single place a fork maintainer edits to add custom skills — so if a skill appears in the registry but not in this document's examples, surface it anyway.

Never execute the recommended skill. Finish with "Say /skill-name to start." and stop.

Shortcut rule — skip questions when intent is unambiguous

Before asking anything, check whether the user's message unambiguously maps to exactly one skill or one chain in the registry. Examples of unambiguous intent:

• "I want to open a PR" → /devenv-open-pr
• "Run pre-commit checks" → /devenv-pre-commit
• "Triage issue #42" → /devenv-triage-issue
• "I want to go from raw idea to merged PR" → Chain A from the registry

If unambiguous: give the recommendation directly with a one-line rationale. Skip Q1–Q3.

Bug-routing shortcut:

• If the user asks to hunt for bugs broadly, by class, or in a focus area/module (without a single known concrete bug to root-cause), route to /devenv-tech-debt-audit.
• If the user has a specific known bug to diagnose/root-cause/fix, route to /devenv-bug-fix.

Question protocol

Ask only what you need. If the user's initial message already answers a question, skip it.

Q1 — Work stage (ask if not already clear):

"What are you trying to do right now?"

• 🔍 Explore / think something through
• 📝 Define requirements for a system or feature
• 🏛️ Architect a system / produce a blueprint or roadmap
• 📋 Create or update an implementation plan
• 🔨 Build / implement something
• 🔎 Review code or address PR feedback
• 🏁 Wrap up a session / open a PR

Q2 — Architecture intent disambiguation (ask only if stage is "Architect"):

"Which architecture outcome do you want right now?"

• Weigh options and get a recommendation first
• Groom component-level design direction (new vs refine vs redesign)
• Produce system-level architecture (blueprint/roadmap)

Routing for this answer:

• Weigh options first → /devenv-design-discussion
• Component-level design direction → /devenv-grooming
• System-level architecture → /devenv-create-blueprint (or /devenv-create-roadmap if architecture already exists)

Q2 — Plan exists? (ask only if stage is "Build"):

"Does a plan file or GitHub issue with a task list already exist for this work?"

• Yes — plan file or issue
• No — working ad-hoc

Q3 — Impact level? (ask only if stage is "Build" AND plan exists):

"How would you describe the work in this phase?"

• High-impact — touches public APIs, data shape, security, or novel architecture
• Mechanical — refactors, renames, test scaffolding, cleanup, docs

Decision logic

Use the registry to match the user's answers to a skill:

1. Match Q1 (work stage) to a registry category — Explore, Requirements, Architecture, Plan, Build, Review, or Wrap-up.
2. Within that category, match the sub-goal to a skill's trigger phrases.
3. Apply stage-specific guardrails before finalizing:
   • Feature-discovery guardrail: when the ask is to add a feature in an existing component and the user is still deciding the best approach, route to /devenv-design-discussion first.
   • Feature-delivery guardrail: when the ask is to add/implement a feature in an existing component and the approach is already chosen, route to Plan/Build.
   • Architecture guardrail: default component-level architecture intake to /devenv-grooming unless the user explicitly requests one specialized design skill.
   • Upstream-artifact guardrail: if the user wants to plan from a design-discussion or spike artifact and no grooming artifact exists yet, route to /devenv-grooming first unless the user explicitly asks to bypass grooming.
   • Direct-plan exception guardrail: if the user explicitly wants to create a plan without grooming (for example thin-air context, mixed pasted notes, or unclassified artifacts), route to /devenv-create-implementation-plan (or /devenv-plan-from-spec when a concrete spec exists).
   • Source-precedence guardrail: when a grooming artifact exists, treat grooming as the directing source of scope/slice boundaries over side-stream artifacts.
   • Side-stream-input guardrail: side-stream artifacts may appear with or without grooming; treat them as additional informational inputs, never as scope-directing sources.
   • Architecture guardrail: if the user primarily wants alternatives/trade-offs/recommendation, route to /devenv-design-discussion first.
   • Architecture guardrail: if the user says the current approach is wrong, route to /devenv-grooming, not refine.
   • Architecture guardrail: if the user has one bounded plan blocker/question that needs deep option-weighing, route to /devenv-design-discussion; if the user describes accumulating questions, entangled decisions, or likely sweeping design changes, route to /devenv-grooming.
   • Build guardrail: do not route high-impact build phases to /devenv-delegation.
   • Escalation guardrail: if the user is mid-execution with a small local plan adjustment, stay in execution; if they want to return to planning for broader plan surgery, route to /devenv-refine-implementation-plan; if they describe one large blocker/question, route to /devenv-design-discussion; if they describe accumulated architectural issues, route to /devenv-grooming.
   • Plan-size guardrail: if the user says plan creation is too large/risky for one issue, route to /devenv-grooming for Feature/Fix/Task redivision, then back to /devenv-create-implementation-plan or /devenv-plan-from-spec for one selected slice.
   • Bug-hunt guardrail: for broad/focused bug hunting (including "find race conditions", "hunt null bugs", "audit auth module for bugs"), route to /devenv-tech-debt-audit.
   • Bug-investigation guardrail: for one known failing behavior/issue/incident, route to /devenv-bug-fix.
4. Check for a chain — if the user's goal implies a multi-step workflow (e.g. "I want to implement this whole story", "from idea to PR"), look up the matching chain in the registry and recommend the full sequence.
5. Check for fork-added skills — after the primary recommendation, scan the registry for any skills not present in the five standard categories. If any exist, surface them: "This workspace also has: /custom-skill — [one-line purpose]."

Ambiguity breaker for existing-component feature asks

If the user's wording contains both "existing component" and "new feature", do not assume this is purely build/delivery.

Ask one direct question:

"Are you trying to implement the feature now, or decide the architecture/design direction first?"

Route as follows:

• Implement now → Plan/Build path:
  • No plan exists → /devenv-create-implementation-plan
  • Plan exists + high-impact → /devenv-pair-programming
  • Plan exists + mechanical → /devenv-delegation
• Decide architecture/design direction first → architecture path:
  • Weigh alternatives/trade-offs first → /devenv-design-discussion
  • Route component-level design intake and classification → /devenv-grooming
  • Use specialized design skills directly only when explicitly requested

If the user answers "not sure yet", treat it as "decide architecture/design direction first" and route to /devenv-design-discussion.

Escalation routing shortcut

If the user indicates they are in /devenv-pair-programming or /devenv-delegation, route by problem size:

• Small local question / task-scope change -> stay in the execution skill and update the plan there.
• One large blocker / design question -> /devenv-design-discussion
• Accumulated questions / architectural drift / likely sweeping redesign -> /devenv-grooming
• Design settled and now tasks/phases need restructuring -> /devenv-refine-implementation-plan

Representative escalation chains:

/devenv-pair-programming or /devenv-delegation
   → /devenv-design-discussion <plan>        (single bounded blocker)
   → /devenv-refine-implementation-plan      (apply bounded plan updates)
   → back to execution skill

/devenv-pair-programming or /devenv-delegation
   → /devenv-grooming <plan>                 (accumulated design issues)
   → /devenv-refine-implementation-plan      (apply broader plan updates)
  → back to execution skill

If the user provides a plan file/issue directly to a design skill (skipping refine-plan), the design skills can read the plan and orient themselves using the plan architectural review protocol.

If the user is unsure which design skill applies for a component-level change, recommend /devenv-grooming first.

Output format

Single-skill recommendation

Recommended: `/skill-name`
Why: <one sentence rationale tied to the user's answers>

Also consider:
- `/skill-name` — <when this would be the better pick instead>

Say `/skill-name` to start.

Omit "Also consider" when the recommendation is clear-cut.

Chain recommendation

When the user's goal spans multiple skills, show the full chain:

This goal spans multiple skills. Here's the full sequence:

1. `/first-skill` — <why this step>
2. `/second-skill` — <why this step>
3. `/third-skill` — <why this step>
   ...

Start here: `/first-skill`

Use the chain definitions in the registry verbatim. Don't invent new chains.

Principle skills

These five are the core of the catalog. If the user is unsure where to start with a non-trivial piece of work, nudge toward them:

1. /devenv-create-implementation-plan — before any significant work begins
2. /devenv-pair-programming — collaborative, human stays in control
3. /devenv-delegation — delegated execution support for mechanical work, user reviews and owns outcomes
4. /devenv-spike — when you don't know if something is feasible yet
5. /devenv-code-review — close the loop after implementation

Anti-patterns

• Launching the recommended skill yourself — always end with "Say /skill-name to start."
• Asking more than 3 questions — if you still can't decide after 3, give your best recommendation with a caveat.
• Recommending /devenv-delegation for high-impact work — escalate to /devenv-pair-programming.
• Recommending /devenv-pair-programming for pure exploration — start with /devenv-rubber-duck or /devenv-spike.
• Routing broad bug hunting to /devenv-bug-fix — use /devenv-tech-debt-audit; reserve /devenv-bug-fix for a specific known bug.
• Recommending /devenv-create-implementation-plan when a plan already exists — that's /devenv-refine-implementation-plan or /devenv-plan-update.
• Routing existing-component feature delivery to architecture by default — default to Plan/Build (/devenv-create-implementation-plan, /devenv-pair-programming, /devenv-delegation) unless the user explicitly asks for architecture option-weighing or design-artifact work.
• Skipping /devenv-grooming for ambiguous component design intake — use grooming as the default classifier unless the user requested a specific design skill.
• Skipping /devenv-grooming when planning directly from design/spike artifacts without coordination context — route through grooming first unless the user explicitly opts out.
• Treating side-stream artifacts as scope-directing — whether grooming exists or not, use them as additional informational inputs only; when grooming exists it directs scope, otherwise confirm boundaries in plan interview/approval gates.
• Ignoring plan-size escalation signals — when one plan is too large/risky, route to grooming for issue redivision before continuing planning.
• Skipping the architecture disambiguation question when stage is Architect and intent is not explicit.
• Recommending a single skill when the user described a multi-step goal — check the registry chains first.
• Hard-coding skill knowledge — always consult the registry; it may contain fork-added skills not listed here.
