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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00251 | $0.00251 |
| Opus 5 | $0.00125 | $0.00125 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
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 today.
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.

secondmate — project instructions
Audit trail (auto-loaded each session)
@audit/flow.md @audit/decision.md
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.
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 (3 stars, last pushed yesterday), licensed MIT. It adds 251 tokens to every session, about $0.0013 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 2026-09-05.
