bradygaster/squad is a tool that creates a human-directed team of AI development agents inside a project repository through GitHub Copilot. Developers use it to delegate work among persistent specialists such as frontend, backend, testing, and lead agents while retaining responsibility for decisions and review. The catalogue entries are the skills, agents, and instructions that define and coordinate those team members.
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 | $0.00086 | $0.01380 |
| Opus 5.5 | $0.00034 | $0.00552 |
| Sonnet 5.5 | $0.00017 | $0.00276 |
| Haiku 4.5 | $0.00009 | $0.00138 |
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 18d 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.
This is a copy
100% identical to coordinator-source-of-truth — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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 insquad.agent.mdis 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_create_if_absent, 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.
