What is SSOT-SKILL AGENTS.md?

Repository instructions for SSOT-SKILL, a group of skills that keeps important repository facts in a single Markdown-based record. SSOT means “single source of truth.”

Use them before substantial work, when starting or repairing the repository record, after major changes, or when checking whether the record is healthy and current.

They define how agents should read, create, check, and update that record so repository knowledge does not become scattered or outdated.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01398	$0.01398
Opus 5	$0.00699	$0.00699
Sonnet 5	$0.00280	$0.00280

Security

Grade C, and why

SSOT-SKILL AGENTS.md scanned grade C with 2 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 8d 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.

What This Repo Is

SSOT-SKILL is a lifecycle skill bundle for software repositories. It organizes long-lived repository facts into a Markdown SSOT/ system. The bundle contains six skills:

Skill	Role
`ssot-preflight`	Read repository SSOT before substantive work
`ssot-bootstrap`	Create or continue repository SSOT structure
`ssot-closeout`	Update SSOT after a substantive change batch
`ssot-audit`	Catch up historical commits, sessions, or protocol versions
`ssot-doctor`	Health check, stop review, CORE-REF, ADAPTER, CONSUMPTION
`ssot-skill`	Compatibility shim; routes to one of the five above

Install

When a user asks you to install or reinstall this bundle, follow INSTALL.md. The short form:

curl -fsSL https://raw.githubusercontent.com/huangpufan/SSOT-SKILL/main/install.sh | bash -s -- --quickstart

For upgrade or uninstall, see bash install.sh --help.

Usage

After install, restart the agent session so skills are discovered. Then use:

$ssot-preflight — before starting any substantive repository work
$ssot-bootstrap — when SSOT/ is missing or bootstrap is incomplete
$ssot-closeout — before final response, claim_done, or commit
$ssot-audit — when the user asks to sync commits/sessions/protocol
$ssot-doctor — for health checks or stop review before high-impact claims

Language

Skill protocol text (SKILL.md, references/) is in English for routing accuracy.
Bootstrap templates ship in both en/ and zh/; the installer copies one language based on --lang.
Consumer-facing SSOT/ documentation follows the consumer repo's documentation_language lock.

Repo Boundaries

install.sh is the installer entrypoint; do not modify unless the skill list or agent registry changes.
skills/*/SKILL.md is the protocol authority for each skill.
skills/ssot-bootstrap/assets/templates/{en,zh}/ contains template files; keep en/ and zh/ in file-name parity.
skills/*/agents/openai.yaml must stay in sync with each skill.
VERSION and skills/ssot-preflight/SKILL.md metadata.protocol_version must match (CI enforces).
CHANGELOG.md follows Keep a Changelog format.

Changes

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.
