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 | $0.00354 | $0.00354 |
| Opus 5.5 | $0.00142 | $0.00142 |
| Sonnet 5.5 | $0.00071 | $0.00071 |
| Haiku 4.5 | $0.00035 | $0.00035 |
Grade A, and why
secondmate CLAUDE.md 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 6d 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
secondmate — project instructions
Audit trail (auto-loaded each session)
@audit/INDEX.md
That index is generated and bounded (most recent entries only) — never hand-edit it. Full history is
one file per task under audit/flow/ and audit/decision/; look it up on demand with
bin/audit-log.py list|search|show, never by loading it in bulk.
Docs must stay in sync with code
Before every git push, update README.md and docs/ARCHITECTURE.md to reflect any changes to:
bin/scripts (new scripts, changed flags, changed defaults)skills/secondmate/SKILL.md(new phases, changed patterns, updated commands).claude-plugin/plugin.json(version bumps)- Herdr integration patterns (pane/agent/worktree usage)
Specifically keep current:
- Version badge in README
- "What's inside" component table (add/remove/update rows for bin/ changes)
- "How it works" mermaid diagram (if the flow changes)
- Config vars table (
SM_*env vars) - Manual install selfcheck command (add new
--selfcheckcalls) - ARCHITECTURE roles table, flowchart, stage-by-stage descriptions, component map
Never push without checking these. If a bin script changed, the README table must reflect it. If the skill changed, the ARCHITECTURE stages must reflect it.
Before relying on memory for this check, run the drift-report skill (skills/drift-report/SKILL.md) — it checks these same docs against the real bin/ scripts for you.
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.

secondmate CLAUDE.md is an instructions file published in the GitHub repository eshwarvijay/secondmate (6 stars, last pushed 4d ago), licensed MIT. It adds 354 tokens to every session, about $0.0014 per session on Opus 5.5. 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 2026-09-05.
