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.

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 | $0.00031 | $0.00448 |
| Opus 5 | $0.00015 | $0.00224 |
| Sonnet 5 | $0.00006 | $0.00090 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
solidify-mistake 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 7d 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
Solidify Mistake（固化错误）
把 agent 失败转成最小 durable guardrail。
触发时机
以下情况使用这个 skill：
- 同类 mistake 出现第二次。
- 单次 mistake 影响很高。
- agent 误解需求。
- agent 违反架构边界。
- 验证被跳过或被错误声称完成。
- 过期上下文导致错误工作。
必读材料
docs/mistake-log.mddocs/product.mddocs/architecture.mddocs/status.md- 相关 tests、scripts、prompts 或 skills。
流程
- 描述发生了什么。
- 描述预期行为。
- 识别 root cause。
- 分类失败。
- 选择能防止复发或暴露复发的最小 guardrail。
- 更新相关 artifact。
- 在
docs/mistake-log.md添加条目。 - 定义后续验证。
失败分类
- 需求理解错误。
- 架构边界违规。
- 漏掉边界条件。
- 缺少验证。
- 重复坏模式。
- 不安全操作。
- 上下文过期。
护栏优先级
选择最轻但有效的 guardrail：
- 文档规则。
- Test case。
- Prompt update。
- Script check。
- Lint rule。
- ADR update。
- Skill update。
产出
- 失败分类。
- 根因。
- 已添加的 guardrail。
- Mistake log 条目。
- 验证步骤。
边界
- 不要为每个第一次出现的低影响错误添加自动化。
- 如果轻量 guardrail 已经有效，不要选择更重的 guardrail。
- 不要只把 mistake 留在聊天历史里。
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.
- 7d ago First seen · 75 lines · 31 tokens per session scan A bb3c734eace7
solidify-mistake is a skill published in the GitHub repository CadeYu/vibe-harness (5 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 448 once invoked, about $0.0002 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 2026-08-31.
