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.

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 | $0.00965 | $0.00965 |
| Opus 5.5 | $0.00386 | $0.00386 |
| Sonnet 5.5 | $0.00193 | $0.00193 |
| Haiku 4.5 | $0.00097 | $0.00097 |
Grade A, and why
squad squad-routing-guard.instructions.md 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 1mo 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
🚦 Squad Routing Guard
Read this before handling ANY non-trivial task in this repository.
If you are a generic Copilot session (not a named squad agent), your first job is to route — not to act. Specialist squad agents own well-defined domains. Taking over their work produces inconsistent results and loses their accumulated context.
Step 1 — Am I Already a Named Agent?
If you were spawned as a named Squad agent (any cast name in .squad/casting/registry.json), skip this file — your charter governs you. Proceed with your charter from .squad/agents/{your-name}/charter.md.
If you are a generic Copilot CLI session, continue reading.
Step 2 — Routing Decision Tree
Is this a trivial one-off question (no code/file changes needed)?
└─ YES → Answer directly. No routing required.
└─ NO → Continue ↓
Does the issue/PR/task have a squad:{name} label?
└─ YES → That agent owns it. Do NOT handle it. Route it. (See §4)
└─ NO → Continue ↓
Does the work type match a specialist domain? (See §3 + .squad/routing.md)
└─ YES → Route to that specialist. (See §4)
└─ NO → Handle it yourself as a generic task.
Step 3 — Routing Table
Read .squad/routing.md and use its current Work Type and Route To/Agent
columns. That file is the only authoritative work-to-agent mapping. Do not cache
agent names in this instruction file or infer ownership from a previous cast.
Before routing:
- Confirm the destination appears in the active
## Memberstable in.squad/team.md. - Use the member name exactly as written there when constructing a
squad:{slug}label or spawning the agent. - If no routing row matches, use the active Lead identified by role in
team.md. If no Lead exists, handle the task as generic work rather than inventing an owner.
Examples — what NOT to grab
❌ "Fix the TypeScript compilation error in src/adapter/"
→ Look up the current runtime owner in routing.md
❌ "Add tests for the casting module"
→ Look up the current quality owner in routing.md
❌ "Update the README with the new CLI flags"
→ Look up the current documentation owner in routing.md
✅ "What does .squad/routing.md say about label taxonomy?"
→ Trivial lookup question — answer directly
✅ "Help me write a quick git commit message"
→ Generic, no specialist needed — handle directly
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.
