In plain words
What is it for?
Guiding changes to skills, agent definitions, platform manifests, documentation, and related project checks.
Why use it?
It gives an agent the local rules needed to edit this repository without overlooking its structure or publishing workflow.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions subagents; mentions AGENTS.md.

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

clairvoyance 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 8d 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.

AGENTS.md

Guidance for AI coding agents working in this repository. For what Clairvoyance is and how to install it, see README.md.

Layout

  • skills/<name>/SKILL.md: the skills themselves, each with YAML frontmatter (name, description) and optional references/ files. This is the product.
  • agents/: subagent definitions used by skills (e.g. clean-room-alternative.md for design-it-twice).
  • evals/<skill>/: claude plugin eval suites. Each suite's README explains how to run it and what its graders score.
  • Platform manifests: .claude-plugin/, .codex-plugin/, .cursor-plugin/, .kimi-plugin/, .agents/, .codex/, .gemini/, .opencode/, gemini-extension.json, plugin.json, package.json.
  • docs/: the clairvoyance.fyi site (Astro). It reads skills/ at build time, so skill edits show up there automatically.
  • server.json: the hosted MCP server's entry for the official MCP Registry. Its version is kept in sync by scripts/bump-version.sh.
  • docs/edge/: the Cloudflare Worker in front of the site. It serves Markdown versions of pages via Accept: text/markdown and the read-only MCP server at /mcp. Cloudflare Workers Builds deploys it on every push to main. To deploy by hand, run npx wrangler deploy from that directory with CLOUDFLARE_ACCOUNT_ID set.

Writing skills

  • Skills translate A Philosophy of Software Design into checks an agent can run on real code. New or changed guidance should reinforce that philosophy, not general code-review advice.
  • Follow the writing-skills process: write a failing scenario first, then the skill, then verify.
  • A skill's description decides when it triggers. Changes to a description can change triggering for neighboring skills, so re-run the relevant eval suite.
  • Keep SKILL.md focused; move long reference material into references/.
  • The pillar each skill belongs to is defined in docs/src/utils/skills.ts. Add new skills there too.

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.
