AGENTS.md

claude-skill-registry-core AGENTS.md is an instructions file for Codex, OpenCode from majiayu000/claude-skill-registry-core. It costs 695 tokens per session, scanned A, a copy of claude-skill-registry AGENTS.md, MIT.

Repository instructions for the Claude Skill Registry Core project, which manages a collection of reusable instructions for AI coding agents. They explain which repository owns the source code, archived skill files, and published output.

In plain words
What is it for?
Use them when editing registry discovery, downloads, security checks, indexes, publishing workflows, or archived skill content across the related repositories.
Why use it?
They prevent changes from being made in the wrong repository or conflicting with the project's publishing rules.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is majiayu000/claude-skill-registry-core's own configuration. It tells Codex and OpenCode how to work on claude-skill-registry-core itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-skill-registry-core configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-skill-registry-core AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to claude-skill-registry AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Repository Policy (Core-First)

  • Core repo is the source of truth for scripts, workflows, index generation, site outputs, and pipeline docs.
  • Data repo stores the archived skill tree in category-at-root layout: <category>/<skill>/SKILL.md + <category>/<skill>/metadata.json.
  • Main repo is a merged publishing artifact (core + data). During publish, the archive is mirrored under main/skills/**.
  • If behavior or docs conflict across repos, follow core implementation and sync others to match.

Repo Identity Map

  • claude-skill-registry-core: authority repo for discovery, download, dedupe, security scan, registry generation, search-index generation, Pages, and publish orchestration.
  • claude-skill-registry-data: archive repo for the heavy skill contents and archive-specific metadata.
  • claude-skill-registry: merged publish artifact for browsing and compatibility consumers.

Edit Routing

  • If a task touches discovery, download, dedupe, security scan, registry generation, search-index generation, Pages, or dispatch/publish logic, edit claude-skill-registry-core.
  • If a task touches archived skill bodies, archive-only metadata, or archive README counts/layout, edit claude-skill-registry-data or let core workflows update it.
  • If a task touches merged-artifact packaging that is intentionally main-owned, edit claude-skill-registry.
  • In main, do not directly edit generated outputs such as skills/**, registry.json, registry_summary.json, docs/search-index.json, docs/stats.json, docs/categories/**, or pipeline scripts mirrored from core.

Publish Contract

  • Canonical flow: core sync-data -> data commit -> core metadata commit -> core build-index -> main publish-from-core.
  • main should use provenance/merge-source.json to identify the exact core_sha and data_sha that produced the current merged artifact.
  • If core and main disagree, treat core as authoritative and re-publish main instead of patching generated files in place.
  • Main-owned workflow exceptions are intentionally excluded by core/scripts/sync_main_repo.sh; today that is .github/workflows/publish-from-core.yml, .github/workflows/metadata-compliance.yml, and the deprecated .github/workflows/sync-data.yml.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
