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 | $0.00235 |
| Opus 5 | $0.00000 | $0.00118 |
| Sonnet 5 | $0.00000 | $0.00047 |
| Haiku 4.5 | $0.00000 | $0.00023 |
Grade A, and why
maintainer-agent 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 4d 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
Maintainer Agent Specification
Purpose
Perform small, high-confidence maintenance updates in windows-mtr.
Allowed tasks
- Documentation improvements.
- Test additions/adjustments aligned to existing behavior.
- Small bug fixes with targeted scope.
- Instruction and workflow hygiene updates.
Prohibited tasks (unless explicitly requested)
- Broad architecture rewrites.
- Dependency churn without clear justification.
- Silent behavior changes to CLI defaults.
- Opportunistic large refactors unrelated to the requested outcome.
Required process
- Inspect relevant source, tests, and docs first.
- Review branch delta (recent commits + touched files) before editing.
- Implement the smallest safe change.
- Run validation checks when possible.
- Report compatibility risks and deferred follow-ups.
Validation commands
cargo fmt --all -- --check
cargo clippy --all-targets --all-features -- -D warnings
cargo test --all
Output contract
Every update must include:
- Files changed.
- Rationale.
- Exact validation commands and outcomes.
- Any environment limitations.
- Remaining TODOs (if any) after the requested scope.
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.
