grafel: Instructions file for Codex

AGENTS.md

grafel AGENTS.md is an instructions file for Codex, OpenCode from cajasmota/grafel. It costs 4,728 tokens per session, scanned A, original, MIT.

A contributor instruction file for Grafel, a project with an MCP interface for AI agents. It defines repository rules such as branch use, worktree layout, GitHub account requirements, and documentation locations.

In plain words
What is it for?
Guiding Grafel development, including branch and worktree setup, GitHub operations, architecture decision records, and quality-test fixtures.
Why use it?
It helps coding agents follow the project's contribution process and avoid unsafe or incorrect repository operations.

Instructions file for CodexOpenCode

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

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

grafel 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 1mo 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.

grafel — Contributor Agent Guide

If you're an AI agent helping develop grafel itself, follow these conventions. End-user-facing guidance for agents calling grafel via MCP is delivered through the MCP instructions handshake (wired into internal/mcp/server.go), not from this file.

Repo conventions

  • Branches: feature branches only, never push to main
  • Worktrees: grafel-worktrees/<branch-name> per concurrent stream
  • GitHub identity: all gh / GitHub operations MUST use the repo owner's personal account (cajasmota) — never any other or secondary (work) account that may be authenticated on the machine. Verify the active account (gh auth status) before any write; if a non-personal account is active, switch back first. (Spawned worker agents are local-only and must not run gh at all — the coordinator owns all GitHub writes.)
  • ADRs in docs/adrs/, numbered sequentially
  • Quality fixtures in internal/quality/golden/; they hold a recall ratchet, not 100% recall. As measured on 72c7848ca (2026-08-08) by scripts/quality/run.sh --runs 1, 6 of 20 fixtures reach 100% must-have recall, 12 fall short, and 2 (groovy-grails-mini, swift-swiftui-mini) carry no expected.json and are not graded at all. Per-fixture figures live in internal/quality/golden/baseline.json; re-derive them with scripts/quality/run.sh --runs 1 --update-baseline. The convention is scripts/quality/run.sh --ratchet: recall may not drop below the recorded baseline, and a rise fails too until you record it. Nothing invokes it for you — .github/workflows/quality.yml is workflow_dispatch only — so run it yourself on any change that touches extraction. The one part that is automatic is go test ./internal/quality -run TestBaseline, which enforces the baseline's structure without indexing anything. (Refs #6231)

Coverage matrix update — mandatory for capability-changing PRs

When your PR adds, modifies, or fixes a capability that's tracked in the coverage matrix, the PR MUST also update docs/coverage/registry.json to reflect the change. The matrix is the source of truth for grafel's capabilities; PRs that ship code without updating the matrix create drift that erodes the matrix's value.

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.
