coordinator-source-of-truth

coordinator-source-of-truth is a skill for Claude Code, Codex from github/gh-aw. It costs 86 tokens per session (1,371 once invoked), scanned A, original, MIT.

A reference that explains which project files are authoritative, which are generated or append-only, and who may read or change them.

In plain words
What is it for?
It helps decide where team state belongs, who can edit it, and which source takes precedence when files disagree.
Why use it?
AI teams can otherwise put information in the wrong file or overwrite state that another process owns. The hierarchy gives them rules for resolving those conflicts.

About the project

GitHub Agentic Workflows is a GitHub CLI extension that lets developers define AI-assisted repository automation in Markdown and run it through GitHub Actions. It is intended for tasks requiring interpretation or reasoning, such as issue triage, pull-request review, CI investigation, documentation maintenance, and dependency analysis. The catalogue entries provide skills and agents for working with these workflows.

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

coordinator-source-of-truth 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 3d 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Load this skill when: the coordinator (or any agent) needs to resolve a "where does this state belong?" or "who is allowed to write this file?" question — e.g., when about to write .squad/decisions.md, when reviewing whether an agent broke the append-only rule, when answering a user question about Squad's file layout, or when adjudicating a conflict between two files. The short summary in squad.agent.md is for routing; this skill is the full reference.

State backend note

Files below marked as "Derived / append-only" are mutable state — agents access them with runtime state tools (squad_state_read, squad_state_write, squad_state_append, squad_state_delete, squad_state_list). The runtime decides whether the configured backend stores them on disk, git-native state, or an external provider. Files marked as "Authoritative" are static config and always live on disk regardless of backend.

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.
