axiom AGENTS.md

Repository-specific instructions for axiom, a marketplace for Claude Code and Codex add-ons. They describe the repository layout, authoritative catalog files, and which files own particular data.

In plain words
What is it for?
Use them when changing axiom's marketplace entries, plugin metadata, repository documentation, or related generated files.
Why use it?
They help agents edit the correct marketplace and plugin files without confusing generated catalogs with their source files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

axiom 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 2d 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.

  • Canonical catalog: .axiom/marketplace.json.
  • Generated catalogs: .claude-plugin/marketplace.json and .agents/plugins/marketplace.json.

Canonical Sources

  • .axiom/marketplace.json owns marketplace identity and ordered plugin names.
  • plugins/<plugin>/.axiom/plugin.json owns common metadata, release version, components, and platform-specific metadata. Semantic-release owns its version.
  • Put Claude-only metadata under platforms.claude and Codex-only metadata under platforms.codex. Do not place host-specific metadata in common fields.
  • .agents/plugins/marketplace.json, .claude-plugin/marketplace.json, and both vendor manifests under plugins/<plugin>/ are generated. Never author them directly.
  • plugins/<plugin>/README.md owns plugin-level docs and must include a non-empty ## Eval history section.
  • plugins/<plugin>/skills/<skill>/evals/evals.json owns shipped eval scenario coverage for that skill.
  • dev/<plugin>/ owns eval run output, grading artifacts, benchmark workspaces, and other non-shipped eval data.
  • The root README.md is partly generated from the sources above. Do not treat generated root README content as canonical data.

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.
