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.

What it costs to keep this loaded
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 | $0.00052 | $0.00253 |
| Opus 5 | $0.00026 | $0.00127 |
| Sonnet 5 | $0.00010 | $0.00051 |
| Haiku 4.5 | $0.00005 | $0.00025 |
Grade A, and why
omd-sast 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 11d 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
/omd-sast — semgrep 静态扫描
对应 pi TUI 的 /omd-sast。确定性工具,直接 Bash 跑 semgrep(装了才可用;没装提示 pip install semgrep 或 brew):
semgrep scan --config auto --json --quiet <目标路径> 2>/dev/null
- 解析 JSON 输出,按严重度分组转述:
file:line+ 规则 id + 一句话问题 + 修复方向; - 零命中就说零命中,不要脑补;规则误报常见——对高严重度命中读代码确认真实可达再定性;
- 与 /omd-audit 互补:sast 是规则事实(便宜、确定),audit 是语义审查(贵、覆盖设计层)。先 sast 后 audit 是省钱顺序。
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.

omd-sast is a skill published in the GitHub repository AbyssCN/oh-my-dag (39 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 253 once invoked, about $0.0003 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.
