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 | $0.00081 | $0.01073 |
| Opus 5.5 | $0.00032 | $0.00429 |
| Sonnet 5.5 | $0.00016 | $0.00215 |
| Haiku 4.5 | $0.00008 | $0.00107 |
Grade A, and why
ssot-preflight scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SSOT Preflight
Before substantive work, find out what the repository's memory says about the task. Read references/memory-model.md, which explains what SSOT/ holds and what the invariants register means, the first time you use SSOT in a session.
1. Find the entry point
- No
SSOT/directory. Tell the user the repository has no SSOT and offer to create one with$ssot-bootstrap. Setup writes a documentation tree and can take more than one session, so it needs the user's yes. If they decline or defer, do the task without the SSOT steps, and do not offer again this session. SSOT/BOOTSTRAP.mdexists. Setup is unfinished. Offer to continue it, and meanwhile use what is already written.SSOT/README.mdhas nossot_format: 3. This SSOT predates v3: usually the v2 layout withSSOT/STATUS.md, sometimes a hand-written one. Read it as knowledge. Its coverage labels and review records are historical, but its adjudications, user constraints, limits, and open questions that bear on the task still bind you. Do not write to it. Tell the user once that$ssot-bootstrapcan migrate it or set it up in the v3 format.
2. Read what this task needs
Read SSOT/README.md, then:
- Invariants. Find the rows whose rule this task could affect, and read the explanation each one links to. Section 3 says what to do when the change could break one.
- Open questions. If one blocks the path this task needs, say so. Only the work that depends on the answer waits; unrelated work goes ahead.
- Known traps and limits. Read the gotchas and the known gaps that touch the parts you will change, and handle each one: fix it, work around it deliberately, or say why it does not apply.
- Routes. Read the files the task routes point to. If no route fits, read the product and architecture entry documents. Do not read the whole tree.
- What you rely on. When an SSOT statement decides how you will implement something, check it against the code first. If they disagree, the code is the current behavior. Note the mismatch so closeout fixes the document, or so you can report the violation.
What ships with it
2 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.

ssot-preflight is a skill published in the GitHub repository huangpufan/SSOT-SKILL (11 stars, last pushed today), licensed MIT. It adds 81 tokens to every session and 1,073 once invoked, about $0.0003 per session on Opus 5.5. 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.
