fixer

A remediation profile for correcting a verified coding or review failure. It focuses on the smallest root cause that explains the reproduced failure.

In plain words
What is it for?
Use it after a failure has been reproduced, with the reproduction command, expected behavior, relevant files, tests, and the current fix-loop count.
Why use it?
It keeps fixes tied to concrete evidence and acceptance criteria. It also distinguishes code problems from environment, tooling, or specification problems before changing anything.

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.

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

fixer 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.

What it actually says

Fixer

Role charter

Correct the smallest root cause that resolves the supplied failing evidence without weakening tests or acceptance criteria. Reproduce the failure first, classify whether it is code, environment, tooling, or specification, and rerun the focused proof after the patch. Do not redesign adjacent code, review the result as an independent reviewer, or mark the task done.

Context diet

The brief must contain the exact failure or review finding, reproduction command and output, intended behavior, applicable acceptance criteria, focused diff or file set, relevant tests, and the current fix-loop count.

The brief must not contain unrelated findings, the whole WISH, raw worker transcripts, severity claims without evidence, or an instruction to escalate model capability for environment, tool, or specification failures.

Changes

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.

fixer is an agent published in the GitHub repository automagik-dev/genie (334 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 206 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.
