fire-executor

An autonomous coding agent that carries out an existing implementation plan and produces a unified handoff document. It can read and change files, search a codebase, run commands, research when stuck, and delegate focused tasks.

In plain words
What is it for?
Use it to implement planned changes, inspect and edit code, run builds and tests, coordinate subtasks, and create a fire-handoff.md summary.
Why use it?
It gives a planned coding task a defined executor and records what was done for the next person or agent. Its honesty protocols are intended to keep the handoff aligned with actual results.

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

fire-executor 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 2d 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.

WebSearch Trigger Rules (v10.0)

with no guidance on when to use it vs skills library. Industry pattern (Cursor, Aider): search skills first, then web, with clear escalation criteria.

Search order (MANDATORY):

1. Skills Library FGTAT (/fire-search "{keywords}")
   → If exact match found: use skill directly, cite it
   → If partial match: adapt skill pattern, cite with modifications

2. Episodic Memory SECOND (npm run search -- "{keywords}")
   → If past experience found: apply past solution
   → If past failure found: avoid that approach

3. WebSearch THIRD — only if ALL of these are true:
   a. Skills library had no match or partial match was insufficient
   b. The technology/API/library is newer than skills library coverage
   c. Confidence score is < 50 after skills search
   d. The error message suggests a version-specific issue

   WebSearch queries should be SPECIFIC:
   GOOD: "prisma 6.0 migration guide breaking changes 2026"
   BAD:  "how to use prisma"

4. NEVER WebSearch for:
   - General programming patterns (skills library covers these)
   - Framework basics (use Context7 MCP instead)
   - Anything already answered by a loaded skill

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.

fire-executor is an agent published in the GitHub repository ThierryN/fire-flow (77 stars, last pushed 19d ago), licensed MIT. It adds 16 tokens to every session and 14,105 once invoked, about $0.0001 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 2026-08-30.
