## Context
When multiple repositories each have their own Squad (AI team), they need to exchange information: knowledge queries, PR reviews, task delegation, and dependency analysis. Each squad has its own agents, MCP tools, and issue tracker — there is no shared runtime.
> **Companion skill — read first:** `cross-squad/SKILL.md` covers **discovery** of peer squads via `squad registry add/list/remove`. This skill picks up after a peer is known and covers the **communication protocols** themselves — the four numbered patterns below: Pattern 0 (synchronous CLI), Pattern 1 (read-only knowledge query), Pattern 2 (git-based async), and Pattern 3 (GitHub-issue-based delegation). A separate non-numbered appendix (Cross-Repo Dependency Scan) is provided as a related analysis tool, not a communication pattern. The two skills are designed to be used together.
**When this skill applies:**
- A squad agent needs information from another squad-enabled repo
- A task needs to be delegated to another squad
- Cross-repo dependency analysis is needed
- PR review requests span repo boundaries
**Key constraint:** Each squad has its own runtime, MCP tools, and issue tracker. Cross-squad communication can be **synchronous** (via CLI session targeting the other repo) or **asynchronous** (file-based or issue-based). The coordinator decides which approach fits.
