--- "mattpocock-skills": patch --- Add `retro` to `in-progress` as a non-functional stub: a raw capture of every idea from the design conversation (determinism hunting, CLAUDE.md→CODING_STANDARDS.md migration, writing-for-agents branch vocabulary applied to review, tool economy off session JSONL, navigation-pointer gaps, codebase-design lens, sub-agents-vs-single-skill architecture, multi-session mode, propose-never-apply). Not reduced to steps or pruned yet — parked for a future `/writing-for-agents` pass.
