The OpenSpec-Siraj pipeline overview. Canonical orchestrator for the siraj-openspec-* family of skills (create-design, create-plan, review-change, stress-test-tasks, stress-test-plan, execute-plan) plus the /siraj-openspec:* CLI commands (new, verify, archive, sync, etc.). Use this skill to orient on the full pipeline (proposal → spec → design → tasks → per-commit plans → execution → verify → archive), to figure out which verb fires next given an OpenSpec change folder's current state, or as the canonical reference for numbering, scenario titles, cross-file references, renumbering, tasks.md commit-block shape, and artifact-tree conventions. Trigger on phrasing like "what's the openspec workflow", "where am I in this change", "walk me through the openspec pipeline", "start a new openspec change", "how do I author tasks.md", or whenever the user pauses on an openspec/changes/<X>/ folder and asks what's next. For lightweight greenfield app/feature builds use feather-flow instead; the two are peer pipelines, not variants. Defaults to the most-recently-modified change folder if no name is given.
