tunelisted

Harness retro — turn recurring agent mistakes into one-line fixes. Mines recent session transcripts (plus the bugfix log and past runs) for repeated corrections, permission friction, and rules that get violated anyway, then proposes ranked changes one at a time: a CLAUDE.md rule, an allowlist entry, a script replacing repeated prose, a new-skill candidate, or a deletion that no longer earns its context cost. Nothing applies without approval; accepted/rejected findings persist in out/tune/learnings.md. Use when the user says "/tune", "improve my setup", "why does claude keep doing X", or after a frustrating session. done's one-line retro catches one lesson at ship time; tune is the periodic audit of the whole harness.

# tune — the harness retro `/tune` — audit the current project's harness against recent sessions `/tune all` — widen across every project under `~/.claude/projects/` Answer one question: **what keeps going wrong across sessions, and what one-line change would make it impossible next time?** Correcting the agent fixes one session; correcting the harness fixes every session after it. The evidence is already on disk — the transcripts recorded every correction, every retyped instruction, every permission prompt. This skill reads them so the user doesn't repeat them. ## Step 0 — Scope, then inventory **Scope:** default is the current project's transcripts — the last ~10 sessions or 2 weeks, whichever is smaller — from `~/.claude/projects/<project-dir>/*.jsonl` (the dir name is the project path with `/` → `-`). `/tune all` widens to every project; mining gets shallower per project, say so. **Inventory the harness first** — findings only mean something against the baseline. Read: user + project `CLAUDE.md`, the installed skills (names + descriptions), `settings.json` / `settings.local.json` (permissions, hooks). Also read `out/tune/learnings.md` (past accepted/rejected — don't re-propose what was rejected), `out/tune/principles.md` if present (promoted cross-cutting principles — a lens for judging new findings), and `out/dev/bugfix-log.md` if present (recurring root causes are harness findings too). ## Step 1 — Mine the transcripts (cheap models, parallel) Bulk transcript rea
