ssot-preflight

ssot-preflight is a skill for Codex from huangpufan/SSOT-SKILL. It costs 80 tokens per session (1,895 once invoked), scanned A, original, MIT.

A repository check that reads the project's single source of truth (SSOT) before substantial development work. It decides whether work can safely begin and what project facts must be recorded.

In plain words
What is it for?
Use it before code, configuration, documentation, reviews, debugging, refactoring, or planning tasks in a repository that maintains SSOT records.
Why use it?
It prevents coding, documentation, or planning from conflicting with unresolved decisions, outdated instructions, or the repository's required documentation language.

Token cost

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.

Security

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 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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SSOT Preflight

You are at the start of substantive repository work. Your job here is not to do the work — it is to decide what's safe to read, what's blocked, and what durable facts you must capture as you go. Do not write code or docs until this gate clears.

Clear the gate

Read SSOT/STATUS.md first. Treat any substantive change as blocked until you have answered, in order:

  • Adjudications. Any pending item under ## 开放裁决项 (or legacy ## 待裁决项), or a deferred item whose revisit condition has fired, blocks ordinary work until resolved or re-deferred.
  • Documentation language. Read documentation_language and its evidence; SSOT Markdown you write this task must match it — except for paths, commands, identifiers, enum values, API names, and direct quotes.
  • Protocol version. Compare this file's metadata.protocol_version against STATUS.md tracked_skill_version. Project behind -> stop, route to $ssot-audit. Installed bundle behind project -> report stale install; never downgrade the project. If a source checkout under projects/SSOT-SKILL/ is newer than the runtime-installed skill copy currently being read (.agents/skills, .codex/skills, .claude/skills, etc.), report the install as stale and reinstall from the source checkout before relying on new protocol clauses.

Route your reads, don't bulk-load

The mandatory floor is SSOT/STATUS.md (adjudications, language, version — cleared above) plus SSOT/README.md as the project-specific router. Read its task-entry map and read only the owners it routes for this task. The 01-product/README.md and 02-architecture/README.md trunks are read only when the task-entry map routes the task to them — not by default. If the task-entry map is missing or does not route the current task, fall back to reading 01-product/README.md and 02-architecture/README.md so a thin-router repo still gets trunk coverage.

Skip this entire skill only for non-repository chat, pure command execution, or mechanical typo/format edits that cannot alter architecture, contracts, state, behaviour, workflows, tests, doc truth, or external surfaces.

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.
