Written for Codex and OpenCode: the file is AGENTS.md. Also seen: built for openclaw.

This is openclaw/carapace's own configuration. It tells Codex and OpenCode how to work on carapace 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 carapace 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

carapace 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 9d 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.

Repository Guidelines

Scope

Carapace owns the canonical OpenClaw web design contract:

  • framework-neutral CSS tokens and themes
  • a thin Tailwind 4 token adapter
  • shared base behavior proven across consumers
  • agent skills that explain how to use and audit the system

Consumer-specific components, routes, and layouts stay in their repositories until at least two consumers share the same interface and behavior.

For OpenClaw and OpenClaw Foundation logos, see the brand kit README.

Commands

  • Bun 1.4.4 is the supported minimum; use the exact packageManager pin for normal development and release work.
  • bun install --frozen-lockfile - install the committed dependency graph.
  • bun run test - parse CSS and verify token/theme contracts.
  • bun run skills:check - validate skill metadata and references.
  • bun run pack:check - verify package exports and packed contents.
  • bun run check - run all validation.
  • Keep the 48-hour dependency maturity window in bunfig.toml; add exclusions only for a named, reviewed dependency.
  • Use mutable bun install only for deliberate dependency changes, and review bun.lock as a security-sensitive generated artifact.

Code

  • Keep JS/TS/JSX source files under about 1,000 lines; split before a file crosses 2,000. Split along ownership seams (markup vs. behavior vs. config), not arbitrary line counts. Generated files and test fixtures are exempt; large test files should still split by surface when practical.
  • Preview markup is queried by attribute at runtime, so keep the contract tests green: binder-queried data-workbench-* hooks must render in at least one workbench state, and every data-lucide icon name must be registered in preview/lucide.js.
  • Candidate CSS ships only selectors a preview specimen renders; delete unvalidated anatomy instead of keeping it speculative.

Release

  • Use Conventional Commits.
  • Release tags are stable semantic versions: vX.Y.Z.
  • The tag must match package.json.
  • Runtime assets release under semantic tags; agent skills update from main.
  • npm publication is not required; consumers install the Git tag.

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.
