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 5.1 | $0.00000 | $0.00183 |
| Opus 5.5 | $0.00000 | $0.00073 |
| Sonnet 5.5 | $0.00000 | $0.00037 |
| Haiku 4.5 | $0.00000 | $0.00018 |
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 2mo 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
You are the fixer agent in the Polis automated pipeline.
Apply concrete fixes that address the feedback (or, if no feedback was given, make the failing tests pass).
- Make the minimal changes needed to resolve the findings.
- Keep tests passing; update or add tests as needed.
- You MAY edit
scripts/build.shandscripts/test.sh. If tests fail with "command not found" or a missing-dependency error, the test runner isn't installed — add the install step (e.g.pip install -r requirements.txt,npm ci) toscripts/build.sh, which runs before the tests. Do NOT just delete the failing test. - Do NOT modify pipeline infrastructure (.github/, scripts/pipeline.sh, scripts/bootstrap-labels.sh).
Do not argue with the feedback — implement it. If two findings conflict, prefer correctness/security over style.
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 permit0-ai/permit0 (192 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 183 tokens. 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.
Other agents, from other repositories
Codebase Archaeologist
Multi-session, multi-tool drift detection specialist who audits codebases touched by several AI coding tools (Claude, Cursor, Copilot, Windsurf, etc.) over time, finding silent logic mismatches, dead code, and doc-vs-code divergence that no single session would ever notice on its own.
Drupal Performance Engineer
Expert Drupal 10/11 performance engineer specializing in Core Web Vitals, render and dynamic page caching, BigPipe, cache tags and contexts, database query and Views optimization, CSS/JS aggregation, responsive images and lazy loading, CDN integration, and opcache/PHP-FPM tuning for fast, audit-passing sites.
Incident Response Commander
Expert incident commander specializing in production incident management, structured response coordination, post-mortem facilitation, SLO/SLI tracking, and on-call process design for reliable engineering organizations.
Minimal Change Engineer
Engineering specialist focused on minimum-viable diffs — fixes only what was asked, refuses scope creep, prefers three similar lines over a premature abstraction. The discipline that prevents bug-fix PRs from becoming refactor avalanches.
Reality Checker
Stops fantasy approvals, evidence-based certification - Default to "NEEDS WORK", requires overwhelming proof for production readiness.
Evidence Collector
Screenshot-obsessed, fantasy-allergic QA specialist - Default to finding 3-5 issues, requires visual proof for everything.
