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 | $0.00012 | $0.01082 |
| Opus 5 | $0.00006 | $0.00541 |
| Sonnet 5 | $0.00002 | $0.00216 |
| Haiku 4.5 | $0.00001 | $0.00108 |
Grade A, and why
cross-squad 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.
This is a copy
100% identical to cross-squad — 0 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
When an organization runs multiple Squad instances (e.g., platform-squad, frontend-squad, data-squad), those squads need to discover each other, share context, and hand off work across repository boundaries. This skill teaches agents how to coordinate across squads without creating tight coupling.
Cross-squad orchestration applies when:
- A task requires capabilities owned by another squad
- An architectural decision affects multiple squads
- A feature spans multiple repositories with different squads
- A squad needs to request infrastructure, tooling, or support from another squad
Patterns
Discovery via Manifest
Each squad publishes a .squad/manifest.json declaring its name, capabilities, and contact information. Squads discover each other through:
- Well-known paths: Check
.squad/manifest.jsonin known org repos - Upstream config: Squads already listed in
.squad/upstream.jsonare checked for manifests - Explicit registry: A central
squad-registry.jsoncan list all squads in an org
{
"name": "platform-squad",
"version": "1.0.0",
"description": "Platform infrastructure team",
"capabilities": ["kubernetes", "helm", "monitoring", "ci-cd"],
"contact": {
"repo": "org/platform",
"labels": ["squad:platform"]
},
"accepts": ["issues", "prs"],
"skills": ["helm-developer", "operator-developer", "pipeline-engineer"]
}
Context Sharing
When delegating work, share only what the target squad needs:
- Capability list: What this squad can do (from manifest)
- Relevant decisions: Only decisions that affect the target squad
- Handoff context: A concise description of why this work is being delegated
Do NOT share:
- Internal team state (casting history, session logs)
- Full decision archives (send only relevant excerpts)
- Authentication credentials or secrets
Work Handoff Protocol
- Check manifest: Verify the target squad accepts the work type (issues, PRs)
- Create issue: Use
gh issue createin the target repo with:- Title:
[cross-squad] <description> - Label:
squad:cross-squad(or the squad's configured label) - Body: Context, acceptance criteria, and link back to originating issue
- Title:
- Track: Record the cross-squad issue URL in the originating squad's orchestration log
- Poll: Periodically check if the delegated issue is closed/completed
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.

cross-squad is a skill published in the GitHub repository alonf/specrew (54 stars, last pushed 4d ago), licensed MIT. It adds 12 tokens to every session and 1,082 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to cross-squad, differing in 0 lines, and is treated as a copy.
