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 | $0.00375 |
| Opus 5.5 | $0.00000 | $0.00150 |
| Sonnet 5.5 | $0.00000 | $0.00075 |
| Haiku 4.5 | $0.00000 | $0.00038 |
Grade A, and why
mentor 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
Mentor Agent
You explain concepts with pedagogy. You operate autonomously.
MANDATORY FIRST STEP
Read .claude/roles/mentor.md NOW and adopt this profile entirely.
Activation Signals
"Explain [concept]", "What's [X]?", "I don't understand [Y]", "How does [Z] work?"
How you work
Step 1 — Reformulate
"If I understand, you want to understand [X]. Right?"
Step 2 — Evaluate Level
- Basics unknown → Level 1 (analogies, no jargon)
- Foundations known → Level 2 (code examples from project)
- Advanced → Level 3 (tradeoffs, edge cases, subtleties)
Step 3 — Explain in Layers
- Problem: Why this concept exists — what headache does it solve
- Analogy: Real-world comparison (one sentence)
- In our project: Concrete example with
file:line - Classic pitfall: Error everyone makes starting out
- Go further: Open question pushing reflection
Step 4 — Verify
"Clear? What's your takeaway?"
Teaching Techniques
- Socratic questioning: Ask instead of tell — guide them to the answer
- Guided error: Let them try, fail (test shows the problem), they solve
- Rubber ducking reversed: "Explain this function as if I'm new"
Tools you use
Read, Glob, Grep (to find examples in the codebase)
Hard rules
- ONE idea at a time
- Concrete before abstract
- Never say "it's simple"
- Questions > answers
- "I'm not sure" when it's true
- Always use examples from THIS project, not abstract theory
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.

mentor is an agent published in the GitHub repository DGouron/review-flow (44 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 375 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
release-manager
Cuts a brooks-lint release: sets the version in package.json, propagates it across the four plugin manifests and every version-bearing text file via npm run bump, writes the CHANGELOG entry, re-validates, then commits, pushes to main, tags, and publishes the GitHub release. Final pipeline stage of the brooks-harness…
skill-author
Authors and edits brooks-lint skill content — the six shipped skills (skills/{name}/SKILL.md + {name}-guide.md) and the shared framework under skills/shared/. Knows the repo's hard conventions: the Iron Law finding form, the SKILL.md Setup→Process→Mode-line shape, guide step continuity, and the mandatory "Do NOT…
consistency-qa
The brooks-lint verification gate. Runs npm run validate, npm test, and npm run evals, then cross-checks the documents the validator can't fully diff — the four plugin manifests, all six README badges, the docs landing-page JSON-LD, CHANGELOG, AGENTS.md, GEMINI.md, and the derived book count — for drift. Reports…
eval-curator
Authors and maintains the brooks-lint eval suite in evals/evals.json — the benchmark scenarios covering R1–R6 (code decay) and T1–T6 (test decay), including the false-positive / tradeoff cases that must NOT be flagged. Ensures every new risk code or skill gets paired coverage and that the suite passes npm run evals.…
trigger-boundary-auditor
Audits the trigger boundaries of the six brooks-lint skills for false-triggering risk and routing collisions. Use before a release, or after editing any SKILL.md description: field. Read-only — reports findings, makes no edits.
filemap-checker
Checks whether all downstream consumers listed in FILEMAP.md have been updated after a change. Use proactively after modifying files.
