+# Squad Bootstrap — installs and initializes Squad (https://github.com/bradygaster/squad)
+# in the activation job only, then republishes the generated team state to the agent job.
+#
+# The Squad CLI is never installed or executed in the agent job — only the files it
+# produces (`.squad/` team state and `.github/agents/squad.agent.md`) are restored there.
+#
+# Usage:
+#   imports:
+#     - shared/squad.md
+#
+# Optional custom credentials for `squad init` (only needed when Squad must reach other
+# organizations or private repositories beyond the current one):
+#   vars.SQUAD_GITHUB_APP_ID / secrets.SQUAD_GITHUB_APP_PRIVATE_KEY / vars.SQUAD_GITHUB_APP_OWNER
+#     — mints a GitHub App installation token for `squad init`
+#   secrets.SQUAD_GITHUB_TOKEN
+#     — used if the App id is not set
+# Auth precedence: GitHub App installation token > SQUAD_GITHUB_TOKEN > the workflow's
+# own default token (`github.token`).
+#
+# Optional custom Squad CLI version (defaults to 0.11.0):
+#   vars.SQUAD_CLI_VERSION
+#
+# No `copilot-sdk` sidecar is needed here: Copilot's `--agent squad` flag runs
+# through the standard CLI harness, and the Squad CLI itself only ever runs in
+# the activation job.

+## Squad Bootstrap Component
+
+This shared component moves the entire Squad (https://github.com/bradygaster/squad)
+install/init lifecycle out of the agent job:
+
+1. **`jobs.activation.pre-steps`** — the repository is already checked out by the
+   activation job itself, so this only installs the pinned `@bradygaster/squad-cli`
+   npm release, optionally mints a GitHub App installation token (or uses a supplied
+   PAT) so `squad init` can see other organizations or private repositories, runs
+   `squad init --preset default` (idempotent), and uploads the resulting `.squad/`
+   team state plus `.github/agents/squad.agent.md` as a dedicated `squad-state`
+   artifact — all inside the activation job, alongside the rest of the
+   prompt/skills/sub-agent packaging.
+2. **`steps:`** (agent job) — downloads the `squad-state` artifact and restores it into
+   the checked-out workspace. The Squad CLI itself is never installed here; only the
+   files it produced are copied in.
+
+-->
+
+## Working with Squad
+
+Squad's team state (`.squad/`) and its Copilot custom agent
+(`.github/agents/squad.agent.md`) were already initialized during activation and
+restored into this checkout before you started — do not install Squad or run
+`squad init` yourself.
+
+- Verify `.squad/team.md` exists before delegating work to the team. If it is
+  missing, the activation-job bootstrap step failed — call `noop` and explain
+  why instead of proceeding.
+- Coordinate work through the Squad team already defined in `.squad/` rather
+  than proposing a brand-new team from scratch.
