Skill Manager

Analyze the current project's tech stack and disable irrelevant globally-installed skills by injecting a bounded section into the project's CLAUDE.md.

When to Use

• User says "manage skills", "optimize skills", "skill manager"
• User says "disable irrelevant skills" or "which skills do I need?"
• User says "clean up skills for this project"
• User says "re-enable all skills"
• At the start of a new project to reduce context window waste

Quick Start

Run the Python analysis script if available, otherwise follow the manual workflow below.

Step 1: Detect Project Tech Stack

Check for these files in the project root (current working directory):

Read package.json dependencies to identify frameworks:

• next -> Next.js
• react -> React
• vue -> Vue
• @angular/core -> Angular
• svelte -> Svelte
• stripe -> Payment processing
• express / fastify / hono -> Node server
• tailwindcss -> Tailwind CSS
• remotion -> Video/media processing

Monorepo detection: If the project has packages/, apps/, or a workspace config in package.json, scan subdirectories too and union all detected stacks.

Empty project: If no recognizable files are found, warn the user and keep all skills active.

Step 2: Read Installed Skills

Read ~/.agents/.skill-lock.json to get the list of all globally installed skills. For each skill, note:

• name (the key)
• source (GitHub repo)
• skillPath (where the SKILL.md lives)

Step 3: Score Each Skill

Assign each skill to a tier based on the detected tech stack.

Tier Definitions

Universal Skills (NEVER disable these)

find-skills, skill-creator, writing-skills, brainstorming,
writing-plans, test-driven-development, dispatching-parallel-agents,
subagent-driven-development, using-superpowers, agentation, skill-manager

Domain Mapping

iOS/macOS Native Skills — essential when Swift/Xcode detected:

• mobile-ios-design (iOS UI/SwiftUI)
• asc-xcode-build (Xcode build/archive)
• asc-metadata-sync (App Store metadata)
• asc-localize-metadata (App Store localization)
• asc-subscription-localization (IAP localization)
• asc-ppp-pricing (territory pricing)
• asc-shots-pipeline (screenshot automation)
• asc-notarization (macOS notarization)
• app-store-optimization (ASO)
• aso-full-audit, aso-optimize, aso-competitor, aso-prelaunch, aso

Web/SaaS Marketing Skills — essential when web framework detected:

• page-cro, signup-flow-cro, onboarding-cro, popup-cro, form-cro
• copywriting, copy-editing, content-strategy
• seo-audit, programmatic-seo, schema-markup
• analytics-tracking, ab-test-setup
• email-sequence, social-content
• marketing-ideas, marketing-psychology
• free-tool-strategy, launch-strategy
• paid-ads, referral-program
• pricing-strategy, competitor-alternatives
• audit-website

Payment Skills — essential when stripe/payment dependency detected:

• stripe-integration
• paywall-upgrade-cro
• churn-prevention

Media/AI Generation Skills — essential when media dependencies detected:

• fal-audio, fal-generate, fal-image-edit, fal-platform, fal-upscale, fal-workflow
• remotion-best-practices

Cross-Domain Rules

• Marketing skills are scored "useful" (50) in non-web projects — users sometimes do marketing from any project
• Stripe/payment skills are "useful" (50) unless stripe is in dependencies, then "essential" (90)
• ASO skills are "essential" (95) for iOS, "irrelevant" (10) for non-mobile
• *fal- skills** are "irrelevant" (10) unless media processing detected
• *asc- skills** are "irrelevant" (5) for non-Apple projects
• remotion-best-practices is "essential" (90) if remotion is in dependencies, "irrelevant" (10) otherwise

Step 4: Check for Overrides

If .claude/skill-manager.json already exists, read the overrides section:

{
  "overrides": {
    "forceEnable": ["seo-audit"],
    "forceDisable": ["fal-audio"]
  }
}

• forceEnable: Move these skills to "essential" tier regardless of scoring
• forceDisable: Move these skills to "irrelevant" tier regardless of scoring

Step 5: Generate .claude/skill-manager.json

Create the .claude/ directory if it doesn't exist. Write the analysis file:

{
  "version": 1,
  "generatedAt": "2026-02-23T12:00:00Z",
  "detectedStack": {
    "primary": "Next.js",
    "languages": ["TypeScript", "JavaScript"],
    "frameworks": ["Next.js", "React", "Tailwind CSS"],
    "platforms": ["Web"],
    "signals": {
      "package.json": true,
      "tsconfig.json": true,
      "next.config.ts": true
    }
  },
  "skills": {
    "page-cro": { "tier": "essential", "score": 95, "reason": "Web CRO directly applicable" },
    "mobile-ios-design": { "tier": "irrelevant", "score": 5, "reason": "No iOS stack detected" }
  },
  "disabled": ["mobile-ios-design", "asc-xcode-build"],
  "enabled": ["page-cro", "stripe-integration"],
  "universal": ["find-skills", "brainstorming"],
  "overrides": {
    "forceEnable": [],
    "forceDisable": []
  },
  "stats": {
    "total": 53,
    "essential": 20,
    "useful": 10,
    "irrelevant": 12,
    "universal": 11
  }
}

Step 6: Update CLAUDE.md

If "re-enable all" was requested:

1. Remove the <!-- SKILL-MANAGER:START --> ... <!-- SKILL-MANAGER:END --> block from CLAUDE.md
2. Delete .claude/skill-manager.json
3. Confirm to user: "All skills re-enabled."
4. Stop here.

Normal flow:

Build the injection block:

<!-- SKILL-MANAGER:START -->
## Disabled Skills

The following skills are **not relevant** to this project and should be **ignored** (do not invoke them):

- `mobile-ios-design` — No iOS stack detected
- `asc-xcode-build` — No Xcode project detected
- ...

**Stack**: Next.js / TypeScript / React / Tailwind CSS
**Last analyzed**: 2026-02-23
**Re-run**: Say "manage skills" or "/skill-manager" to re-analyze
**Re-enable all**: Say "re-enable all skills" to remove this section
<!-- SKILL-MANAGER:END -->

Injection rules:

1. Read the current CLAUDE.md (or note it doesn't exist)
2. If markers exist: Replace everything between <!-- SKILL-MANAGER:START --> and <!-- SKILL-MANAGER:END --> (inclusive) with the new block
3. If no markers: Append the block to the end of CLAUDE.md with a blank line separator
4. If no CLAUDE.md: Create it with only the skill-manager block

IMPORTANT: Do NOT modify any other content in CLAUDE.md. Only touch the bounded marker section.

Step 7: Suggest New Skills (Optional)

If the detected stack suggests skills that aren't installed, mention them:

Based on your Next.js project, you might also want: - npx skills find nextjs for Next.js-specific skills - npx skills find react for React patterns

Only suggest if there's a clear gap. Don't overwhelm with suggestions.

Step 8: Report Summary

Print a summary table:

Skill Manager Analysis Complete

Stack: Next.js / TypeScript / React
Total skills: 53
  Essential: 20 (kept active)
  Useful: 10 (kept active)
  Irrelevant: 12 (disabled in CLAUDE.md)
  Universal: 11 (always active)

Disabled skills written to CLAUDE.md
Full analysis: .claude/skill-manager.json

Automated Mode (Python Script)

If Python 3.9+ is available, you can run the analysis script for faster, deterministic results:

python3 skills/skill-manager/scripts/analyze_project.py --analyze "$(pwd)"

Or just detect the stack:

python3 skills/skill-manager/scripts/analyze_project.py --detect-stack "$(pwd)"

The script path is relative to where the skill is installed. Find it via:

# The skill is installed at ~/.agents/skills/skill-manager/
python3 ~/.agents/skills/skill-manager/scripts/analyze_project.py --analyze "$(pwd)"

The script outputs JSON to stdout. Use the output to populate .claude/skill-manager.json and the CLAUDE.md injection block.

If Python is not available, follow the manual steps above — they produce the same result.

Idempotency

• Running this skill multiple times is safe
• The CLAUDE.md section is replaced, never duplicated
• The JSON file is overwritten with fresh analysis
• User overrides in the JSON are preserved across re-runs

Edge Cases

• Monorepo: Union all detected stacks from subdirectories. More skills stay enabled.
• Empty project: Keep all skills active. Warn user: "No stack detected."
• New skills installed since last run: Automatically picked up on re-run.
• Skill uninstalled: Removed from disabled list on re-run.
• CLAUDE.md has other content: Only the marker-bounded section is touched.
