Skills Curator v4
Install the skill. Customize it to your stack. Decide once, never re-decide.
Other skill managers stop at install. Skills Curator's headline capability is --customize: take any external skill, scan the user's project, and produce a project-tailored fork with examples rewritten for their stack (Vue → React, Django → FastAPI, generic CI → their CI). The engine emits a per-section action plan (keep, keep-trim, rewrite-stack, drop-or-rewrite, rewrite-frontmatter); the agent does the prose. Nothing else in the ecosystem does this.
The second pillar is persistent judgment: every evaluation produces a structured record (pros / cons / conflicts / verdict / partial-adoption plan) saved to a personal registry — so the same skill is never re-evaluated from scratch, and decisions become PR-pasteable artifacts.
Read reference files on demand:
references/commands.md — all commands and flagsreferences/evaluation.md — evaluation format and principlesreferences/discovery.md — how recommendations work, response templates, categoriesreferences/schema.md — registry data model
First activation in a session
The first time this skill activates in a session, open with this two-line orientation before answering, then continue with whatever was asked:
🧭 Skills Curator loaded — your intelligence layer for Claude skills.
I maintain a trust-rated catalog (curated entries + live GitHub topic search), identify what fits your project (stack, deps, CLAUDE.md), and on request return ranked lists with pros, cons, and per-project customization advice — persisting every decision so you don't re-evaluate. Working on your request now.
Skip the orientation entirely if --auto (next section) is about to surface concrete picks — those are more useful than a generic intro. Don't repeat orientation in later messages of the same session.
Proactive activation (the intelligence layer)
Customization is the headline capability; proactive activation is what makes it useful unprompted. Don't wait for the user to say "evaluate this skill" — surface relevant skills when project context implies one would help, and lead with --customize when the skill's stack doesn't match.
Run this at the start of any session in a real project
If the working directory contains CLAUDE.md, package.json, requirements.txt, pyproject.toml, go.mod, or Cargo.toml, run once, silently at the start of the session:
python ~/.claude/skills/skills-curator/scripts/registry.py --auto
--auto is fingerprint-based: it only does a full re-scan when the project has actually changed (new dep, new framework, new CLAUDE.md content). Otherwise it prints a one-line "no changes since last scan" and exits. Cheap to run on every session — designed to be called proactively.
If --auto surfaces top picks, weave them into your first response to the user as a quiet observation, not a sales pitch:
"While we work on this — I noticed you're using Next.js + Tailwind. There's a frontend-design skill (🏛️ official) that adds aesthetic guidelines that match your stack. Want me to evaluate it?"
Re-run when the project shifts
After the user adds/removes a dependency, edits CLAUDE.md, or installs a new framework, run --auto --refresh. The fingerprint will detect the drift.
When the user describes a problem instead of naming a skill
If the user says "my tests are slow", "deploys are manual", "the UI looks ugly", "no one writes good commit messages", or any other complaint that hints at a missing capability, run:
python registry.py --symptoms "<their phrase>"
This maps complaints to skill categories using a built-in symptom→tag table and surfaces matching catalog entries. Don't make the user reverse-engineer "is there a skill for X" — listen for symptoms and recommend.
Don't over-trigger
- Run
--auto at most once per session unless the project actually changes.
- Run
--symptoms only when the user expresses a clear pain point. Don't fire it on every passing reference.
- If
--auto returns nothing strong, say nothing. Silence is a valid answer when the stack is well-covered.
When to activate
The frontmatter when_to_use covers the explicit triggers. One additional rule worth surfacing here:
If the request is "how do I do X?" and X is plausibly a skill domain (testing, deploy, design, scraping, docs, etc.), search the registry and catalog before answering from general knowledge — there may already be a battle-tested skill for it.
The three verbs
These are the three slash commands surfaced in Claude Code. Everything else is in the CLI for power users.
| Verb | When | What it does |
|---|
/skill-evaluate <id-or-path> | User asks "should I install X?" | Security-scans, reads CLAUDE.md, produces ADOPT/PARTIAL/SKIP with full evidence, persists the decision |
/skill-recommend | User asks "what skills fit?" | Scans project, ranks by tag-overlap × trust tier (not popularity), splits capability vs preference |
/skill-audit | User asks "review my skills" | Finds duplicates, preference conflicts, security gaps, stale versions, low-health skills |
Setup
~/.claude/skills/skills-curator/registry.json
python ~/.claude/skills/skills-curator/scripts/registry.py
python "%USERPROFILE%\.claude\skills\skills-curator\scripts\registry.py"
Workflow: discover → evaluate → install
The full path from "what could help here?" to "decision saved" is six steps. Don't skip ahead — each step de-risks the next.
Step 1: Understand what the user actually needs.
What domain (React, testing, design, deployment, scraping, docs)? What specific task? Is this likely common enough that a skill exists?
Step 2: Check the registry first.
If we've evaluated this skill (or one like it) before, surface the prior verdict instead of re-evaluating.
python registry.py --history <skill-id>
python registry.py --search <term>
Step 3: If unevaluated, recommend or discover.
- Project-aware ranking (best signal):
python registry.py --recommend
- Free-text catalog search:
python registry.py --find <query> (alias for --discover)
Step 4: Verify trust before recommending anything.
- 🏛️ Official (Anthropic, Vercel, Microsoft) → safe to surface
- ✅ High (established orgs) → safe to surface
- 🟡 Medium / ⬜ Community / ❓ Unknown → only after
--check <path> security scan
- Never recommend a skill from an unknown author without flagging it.
Step 5: Run the full evaluation (the only step that produces a verdict).
Trigger /skill-evaluate — runs security scan → project scan → reads CLAUDE.md → produces ADOPT/PARTIAL/SKIP with pros/cons/conflicts → persists. Use the output format below.
Step 6: Persist + offer the export.
python registry.py --eval <id> <project> <verdict> "<summary>" --pros "..." --cons "..." --conflicts "..."
python registry.py --export-eval <id>
When no skill fits
If --recommend returns nothing strong, OR --find <query> finds no matches, OR the top match has Medium/Unknown trust + zero evaluations, don't manufacture a recommendation. Instead:
- Tell the user no good match was found and explain why (no tag overlap, low trust, security flags).
- Offer to do the task directly with general capabilities.
- Offer to scaffold a custom skill:
python registry.py --author.
A "no recommendation" answer is a feature, not a failure — it's the whole point of judgment over popularity.
Output format for evaluations
Use this structure exactly. Format matters because it's also what --export-eval reproduces.
## Skill Evaluation: <Name>
Project: <project>
Type: Capability Uplift | Encoded Preference
### ✅ Pros
- <specific, tied to project goals>
### ⚠️ Cons
- <specific cost or limitation>
### 🔴 Conflicts
- <existing skill or pattern that overlaps; "None" if clean>
### 🎯 Verdict: ADOPT | PARTIAL | SKIP
<one or two sentences with the core reason>
### 📦 Adoption Plan
- Adopt: <which features>
- Skip: <which features>
- Pairs with: <skill-id or "nothing">
Don't pad. The user can read between sections; verbose justifications hide the verdict.
Persisting
After the user agrees with a verdict, save it:
python registry.py --eval <id> <project> <verdict> "<summary>" \
--pros "<a>,<b>" --cons "<c>,<d>" --conflicts "<e>"
If the skill isn't registered yet, --add it first.
--customize: the headline capability
Most skills ship with examples written for someone else's codebase. Adopting them means tolerating mismatched examples or rewriting by hand. --customize is the one feature that solves this end-to-end.
python registry.py --customize <source>
What it does, step by step:
- Resolves the source. Accepts a registered skill id, a local path, or a GitHub
owner/repo@skill-name — fetches the SKILL.md from any of them.
- Scans the current project for signals (tags, languages, framework keywords from
package.json, requirements.txt, CLAUDE.md, etc.).
- Splits the source SKILL.md into sections and scores each one against the project's tag set + languages.
- Emits a per-section action plan with one of:
keep, keep-emphasize, keep-trim, rewrite-stack (examples target a stack the project doesn't use), drop-or-rewrite, rewrite-frontmatter.
- Scaffolds the fork at
~/.claude/skills/<name>-for-<project>/SKILL.md with the plan baked in as a table the agent walks row-by-row.
- The agent then rewrites each section per the action column — engine produces the plan, agent does the prose. Vue snippets become React snippets. Django routes become FastAPI routes. Generic deploy scripts become your CI's deploy scripts.
Use --no-fork to preview the plan without writing the fork.
Why this is the USP: installation is a solved problem; adaptation isn't. Every other skill manager assumes one-size-fits-all SKILL.md content. Skills Curator is the only one that treats SKILL.md as a template to be specialized per project — and the only one that does it with a project-aware action plan instead of a blanket find-and-replace.
When you recommend a skill via --recommend and detect a stack mismatch (Vue skill in a React project), surface a one-line --customize hint instead of just suggesting "install it" — that's the moment this feature pays off.
Platform management
Skills Curator supports 55 agent platforms (claude-code and github-copilot are first-class; the rest are reachable via the same migration verbs).
When the user asks "where can I install this?" or wants to copy a skill across platforms, use --platforms and --migrate <target[,...]>. Targets accept a single id, a comma list, or detected (every platform on this machine). Without an explicit target in a non-TTY context, migration defaults to claude-code; in a TTY it prompts.
For "list all supported platforms", run --platforms --verbose — never read the PLATFORMS dict by hand. Full flag reference: references/commands.md.
Common Mistakes
| Mistake | What to do instead |
|---|
Recommending a Medium/Unknown-trust skill without --check first | Trust gate is non-negotiable — security-scan first, flag findings to user |
| Manufacturing a recommendation when no skill fits | Say no good match was found, explain why, offer to do the task directly or scaffold via --author |
| Re-evaluating a skill the registry already has a verdict for | Run --history <id> first; surface the prior verdict instead of re-deciding |
Running --auto more than once per session | Fingerprint-based; one call is enough until the project changes |
| Padding the evaluation output with prose | Use the locked output format exactly — --export-eval reproduces it |
Reading references/commands.md by hand to list flags | Run the engine (--platforms --verbose, etc.) — it renders consistently |
Other commands and tier choice
Full CLI reference: references/commands.md (covers --check, --list, --discover/--find, --health, --stale, --platforms, --migrate, --author, --customize, --sync/--push, --validate).
Tier choice: skills-curator-lite is the default — same intelligence layer, no Python (Bash/Read/Glob/Grep + embedded catalogs). Use the Python version when you have 100+ skills (single-pass speed beats N agent steps), need cross-device Gist sync, or want regression-tested behavior. Both ship in the plugin and use different registry paths — they don't conflict.
