A Copilot CLI extension to run local, commit-sized "baton-pass" workflows across fresh Copilot sessions. It’s for developers who want an agent-based two-stage loop: implement (coder) -> review (reviewer), where each stage runs in a new session and hands off authoritative markdown handoffs. Key features: - Recognizes CHAIN directives in prompts and parses or hydrates chain metadata from a local per-issue ledger. - Injects hidden startup context (stage, chunk, handoff path, HEAD, cleanliness) so the next agent knows exactly what to act on. - Watches for real commits during implement sessions and requests/creates handoff files. - Spawns the next session (Windows Terminal or PowerShell) and injects the handoff; marks handoffs CURRENT or STALE. - Persists ledger at .github\agents\handoffs\CHAIN-LEDGER.json and relies on extension.mjs, handoff SKILL.md/template, and generated HANDOFF-*.md. - Provides a chain_transition tool for reviewers to record verdicts (approved, changes_requested, done) and route the chain. - Stops on missing commits/handoffs, errors, closed issues, budget exhaustion, or explicit done.
