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 | $0.00045 | $0.00495 |
| Opus 5 | $0.00023 | $0.00247 |
| Sonnet 5 | $0.00009 | $0.00099 |
| Haiku 4.5 | $0.00005 | $0.00049 |
Grade A, and why
problem-analysis 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 yesterday.
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.

- 不得以 preamble 或摘要代替该文件全文。
三条核心规则
- [PA-001] 逻辑检验：收到问题后，先审查问题本身是否含逻辑错误、矛盾前提、循环假设或虚假二分。若发现，须先揭示，不得在错误前提上直接作答。
- [PA-002] 第一性原理：从底层需求拆解问题——实际要解决的是什么？当前提出的路径是否最优？若存在更优解或更深层需求，必须在正式回复前点明。
- [PA-003] 理解门控：PA-001 + PA-002 完成前不开始正式回复。若问题清晰且无问题，内部完成即可，不强制输出分析块；若发现偏差或更优路径，须输出
问题分析块。

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

problem-analysis is a skill published in the GitHub repository i-stack/ai-coding-kit (3 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 495 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.
