What problem does it solve? When planning state lives in markdown files tracked by git, answering "what happened to this entity?" requires digging through commit history by hand. This Skill runs aiwf history to surface the full lifecycle of an epic, milestone, ADR, gap, decision, contract, or acceptance criterion directly from structured git commit trailers. ## Core Features & Use Cases - Entity Timeline Retrieval: Runs aiwf history <id> to render one event per line with date, actor, verb, target status, and commit SHA, including forced, audit-only, and reason sub-lines. - Rename-Aware Lineage: Resolves queries through prior_ids so pre-rename, rename, and post-rename commits weave into a single chronological timeline. - Composite and Milestone Views: Queries M-NNNN/AC-N for one acceptance criterion's events, or a bare milestone id to include all of its ACs. - Authorization Provenance: Expands scope-authorization chips with --show-authorization and emits full trailer sets via --format=json. - Use Case: A user asks "why is this gap closed?" or "who authorized this work?" — the Skill runs aiwf history G-NNNN and reports the closing commit, actor, and any [forced: ...] or [audit-only: ...] markers. ## Quick Start Ask the assistant to show the history of an aiwf entity, for example: "Show me what happened to M-0007 including its acceptance criteria."
