bonfire: Instructions file for Codex

AGENTS.md

bonfire AGENTS.md is an instructions file for Codex, OpenCode from vieko/bonfire. It costs 1,250 tokens per session, scanned A, original, MIT.

Repository-specific instructions for AI coding agents working on Bonfire, a system that stores coding memory across sessions and adapts it to different AI tools.

In plain words
What is it for?
Use it when working in Bonfire to understand its structure, preserve key invariants, and keep its Pi, Claude, and fallback integrations consistent.
Why use it?
It gives agents the project context, important rules, and shared file-format contracts they need before changing the code.

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

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

bonfire 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.

Key invariants

  • Fence format is the contract: <!-- bonfire:auto-inflight:start v1 --> and <!-- bonfire:auto-sessions:start v1 -->. Both adapters must produce identical fence shapes; the fallback skill must too. Bump the v1 suffix only with a coordinated migration. conformance.mjs enforces byte-identity — see the sync contract below.
  • Opt-in gate: presence of <git-root>/.bonfire/ directory. Adapters never auto-create it. The opt-in is consciously per-repo.
  • Short session id: ≥8 random hex chars, skipping UUIDv7 timestamp prefixes. Both adapters use slice(8, 16) of the hyphen-stripped UUID.
  • Cap: 5 newest rows in the sessions fence. Older rows drop.
  • De-dupe by [<host>:<short-id>]: same session updates its row instead of duplicating.
  • Garbage + stale detection: in-flight from a different session, or matching /no conversation (content|messages?)/i, gets overwritten.

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.
