SkillForge — Skill Router, Creator & Ecosystem Maintainer

A meta-skill that triages skill requests, builds new skills through a failing-baseline test pipeline, and keeps your whole skill library healthy.

What it does

SkillForge orchestrates anything skill-related in Claude Code:

  • Phase 0 routing: discover_skills.py refreshes an index of your skills and triage_skill_request.py classifies the request into use / improve / create / compose / clarify — so you stop creating duplicates.
  • Evidence-driven creation: first dispatch a fresh subagent without the skill to capture real failures (RED gate). No failure means no skill. Those failures become the test cases and the description keywords.
  • Six phases: analysis (Inversion, Pareto, Root Cause lenses) → spec from a template → generation in a fresh context → behavioral GREEN testing plus trigger checks → a single adversarial reviewer told to refute the skill → ship with an evals/ regression suite.
  • Mechanical gates: validate_skill.py (structure, frontmatter, 1,500-word budget, rejects dated model IDs) and check_docs_safety.py.
  • Ecosystem maintenance: skillforge_doctor.py for trigger collisions, duplicates, stale refs and token budgets; compile_skill.py and package_skill.py for other runtimes and .skill archives.
  • Context Skill Advisor: hook-based proactive suggestions that never auto-invoke; hooks and personal-context scanning are opt-in.

Who it's for

  • People whose skill library has grown enough that overlap and trigger collisions are a real problem
  • Authors who want proof that a skill changes agent behavior, not just a nicely written document
  • Teams standardizing description doctrine, word budgets and regression tests for skills
  • Anyone exporting skills to other runtimes or packaging them for distribution

Examples

  1. "Create a skill for extracting tables from PDFs" → triage searches existing skills first; a strong match is recommended instead, otherwise it captures baseline failures, writes a spec, and generates the new skill.
  2. "Improve my release-notes skill" → baseline the current version, blind A/B judge the revision, then confirm no regression with run_skill_evals.py.
  3. Monthly checkup → skillforge_doctor.py surfaces two skills fighting over the same triggers; rewrite their descriptions as trigger conditions only to stop mis-invocations.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/tripleyak/SkillForge/HEAD/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the SKILL.m folder from the GitHub repo tripleyak/SkillForge into my ~/.claude/skills/skillforge/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/tripleyak/SkillForge.git ~/.claude/skills/skillforge

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and confirm Python: python3 --version (the bundled scripts need Python 3).
  2. Make sure the skills directory exists: mkdir -p ~/.claude/skills
  3. Clone the repo into it: git clone https://github.com/tripleyak/SkillForge.git ~/.claude/skills/skillforge
  4. Verify with ls ~/.claude/skills/skillforge — you should see SKILL.md, scripts/, references/. If SKILL.md lives in a subfolder, move that subfolder into ~/.claude/skills/ instead.
  5. Restart Claude Code, then try "do I have a skill for X?" or "create a skill for ..." to confirm it triggers.
  6. (Optional) Pre-build the index: run python3 scripts/discover_skills.py from the skill folder.
  7. (Optional) For proactive suggestions run python3 scripts/install_skillforge.py — review the hook and personal-context scanning prompts carefully and leave them off if you don't want them.
