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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00055 | $0.00558 |
| Opus 5 | $0.00028 | $0.00279 |
| Sonnet 5 | $0.00011 | $0.00112 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
bonfire 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 5d 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.
What it actually says
Bonfire (fallback skill)
Session context persistence for AI coding.
Bonfire ships in three layers:
- File convention —
<git-root>/.bonfire/index.mdwith two managed fence blocks. - Native host adapters (preferred) — drop-in plugins that auto-update the file as you work. Available for Pi and Claude Code.
- This skill (fallback) — manual
/skill:bonfire endfor agents without a native adapter (Codex, OpenCode, etc.).
If you're on Pi or Claude Code, install the adapter from ~/dev/bonfire/{pi,claude}/ instead. The adapters are zero-ritual and richer than what this skill can do.
Git root: !git rev-parse --show-toplevel 2>/dev/null || echo ""
Opt-in
The skill (and the adapters) honor an opt-in gate per repo:
mkdir <repo>/.bonfire
Without .bonfire/ present, this skill exits silently. That keeps it from polluting random repos.
Routing
| Input | Action |
|---|---|
end |
Read commands/end.md and execute |
migrate |
Read commands/migrate.md and execute. One-off migration for a pre-v7 index.md that lacks the v1 fence markers — wraps the file in fences without destroying hand-curated content. |
Earlier versions of bonfire had start and handoff commands. Both are removed in 7.0:
start: redundant. Modern agents auto-read files fromcwd, so.bonfire/index.mdis already in context. No ritual needed.handoff: Pi has a richer first-partyhandoffextension. For non-Pi agents, use Linear, a notes file consumed via@fileinjection, or a draft PR description.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

bonfire is a skill published in the GitHub repository vieko/bonfire (10 stars, last pushed 11d ago), licensed MIT. It adds 55 tokens to every session and 558 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
