What problem does it solve? Prompt-level changes to squad coordinator and agent charter templates cannot be caught by unit tests because the prompts are interpreted by an LLM at runtime, so regressions only surface during real sessions. This Skill provides a repeatable end-to-end workflow for validating template changes against a locally built CLI before they ship. ## Core Features & Use Cases - Local Build Verification: Builds and links the squad CLI from your feature branch, with fast-fail checks that stop the run on build, link, or version errors. - Disposable Test Repos: Creates isolated git repos, runs squad init, and executes real Copilot CLI sessions with --allow-all-tools to exercise modified templates. - PR Progress Reporting: Posts and updates a live tracking comment on the PR with per-step status, progressive per-scenario verdicts, and a final verdict table. - Use Case: After editing .squad-templates/squad.agent.md to add state-backend-aware spawn logic, run this Skill to build the CLI, init a test squad, run a coordinator session, and verify state landed in the expected git-notes location. ## Quick Start Ask the agent to run end-to-end validation of your squad template changes by building the local CLI, initializing a disposable test repo, and running a Copilot squad session with verdicts posted to the PR.
