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 | $0.00120 | $0.00700 |
| Opus 5 | $0.00060 | $0.00350 |
| Sonnet 5 | $0.00024 | $0.00140 |
| Haiku 4.5 | $0.00012 | $0.00070 |
Grade A, and why
audit-snapshot-micro 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 12d 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.

流程
- 计算 diff 的 sha256（
git diff --no-color) - 收集 test 输出（pytest / npm test 简化输出）
- 调
mcp-audit-log append（event_type:micro_change_seal） - 写 MICRO_AUDIT.json 到 PR 关联位置

不允许
- 用 micro 包装大型变更（先 sop_router 校验）
- 跳过 mcp-audit-log
- 自定义 schema 字段（必须按上表）

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.

audit-snapshot-micro is a skill published in the GitHub repository charliehzm/medharness (86 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 120 tokens to every session and 700 once invoked, about $0.0006 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 2026-08-30.
