Universal Skills Marketplace
Context7 for skills, not docs. One MCP server. Two ecosystems. Unofficial.
Mission
Build, maintain, or extend an unofficial bridge that lets any Claude Code or OpenAI Codex session search one registry for skills originating in either ecosystem, get them back with quality scores + install commands for both CLIs, and load them on demand.
Not affiliated with Anthropic or OpenAI. Identity details in references/00-architecture-overview.md.

Phase dispatcher
- Planning / just arrived → read
00-architecture-overview.md, then10-context7-architectural-analysis.md, thenreferences/11-manifest-translator-algorithm.md(the three anchoring docs) - Phase 0 — spikes complete → evidence in
/docs/spikes/(upstream URLs verified, Codex schema derived, rate limits mapped, iCloud strategy documented) - Phase 1 — schemas + this skill → you are here; running this skill IS Phase 1's deliverable
- Phase 2 — npm package →
packages/mcp-server/implementation driven by04-mcp-tool-design.md+11-manifest-translator-algorithm.md - Phase 3 — Cloudflare backend → three Workers driven by
05-cloudflare-workers-playbook.md+06-d1-schema-design.md+08-github-indexer-design.md
Hard rules (inherited from ../../CLAUDE.md)
- Anti-Fabrication — if a URL, field, or behavior isn't verified against installed plugins or a live upstream, it does NOT ship.
- Anti-Mock-Data — no hardcoded skills anywhere except
assets/fixtures/andpackages/*/tests/fixtures/. - Verification — "build passed" ≠ acceptance;
curl+ fresh Claude Code AND Codex session required. - Translator loudness — no silent field drops; every lossy translation logs + shims.
- context7 fidelity — plugin wrapper stays trivial; all logic in the npm package.
- Identity — unofficial, independent, community project. Never imply endorsement from either company.

The current SKILL.md does not define a fixed output example. Build, maintain, or extend an unofficial bridge that lets any Claude Code or OpenAI Codex session search one registry for skills originating in either ecosystem, get them back with quality scores + install commands for both CLIs, and load them on demand.

# Universal Skills Marketplace
Context7 for skills, not docs. One MCP server. Two ecosystems. Unofficial.
## Mission
Build, maintain, or extend an unofficial bridge that lets **any Claude Code or OpenAI Codex session** search one registry for skills originating in either ecosystem, get them back with quality scores + install commands for both CLIs, and load them on demand.
Not affiliated with Anthropic or OpenAI. Identity details in [`references/00-architecture-overview.md`](references/00-architecture-overview.md#identity-positioning).
