Scan the full conversation. For each finding, cite the specific exchange (quote or paraphrase) and its impact.
| Category | Signal | |----------|--------| | **Mistakes** | Wrong outputs, incorrect assumptions, hallucinated facts | | **Friction** | Repeated clarifications, verbose responses, misread intent | | **Wasted effort** | Work discarded, wrong approaches tried first | | **Wins** | Approaches worth repeating, smooth interactions |
Skip one-time typos, external tool failures, and issues outside agent control.
Collect candidates in the response. A retrospective alone does not authorize memory writes or skill edits; apply only changes already authorized by the user or approved in steps 4 and 5.
If the session included PR or MR review activity in either direction, run this scan before moving on. Skip only if no reviews happened.
**Inbound (my code was reviewed):** For each review comment received:
**Outbound (I reviewed someone else's code):** For each comment I authored:
"No harvestable items" is a valid outcome -- say so explicitly. Don't let the step quietly drop off.
Before listing improvements, scan the session for operational insights worth preserving. Apply the 5-minute filter: would knowing this save 5+ minutes in a future session? If yes, include it. Examples: a project-specific quirk, a project command that failed for a project-specific reason, an approach that worked better than expected.
Exclude harness-level noise — "File has not been read yet", token-limit truncations, bash-quoting slips, and other tooling artifacts. Those aren't project learnings; capture the *project's* behavior, not the agent's mechanics.
Also scan for **information-access gaps**: points where the session stalled or guessed because the agent lacked read access to something a human would have checked — dev-server logs, a third-party dashboard, a staging database, CI output. Distinct from the harness noise excluded above: a one-off tooling hiccup isn't reusable, but a standing access gap is, since granting access pays off in every future session. Each gap is an improvement candidate ("grant readonly access to X" or "pipe X into a file the agent can read"), often higher-leverage than a prompt tweak.
Numbered list of **concrete improvements**, ranked by impact. Each item: one sentence, imperative, actionable. Cap at 10 items: if more surface, the bottom items are noise -- drop them rather than batching or splitting.
For items not already authorized for persistence, present the concrete candidates and ask which to remember. Use the active harness's supported approval interface, or ask directly in chat. Do not ask again for items the user already authorized.
Save authorized items in the project's configured memory location using the active harness's file-editing tool and memory format. In Claude Code, inspect `~/.claude/projects/<project-slug>/memory/` and its MEMORY.md index; use the configured project slug rather than inventing one.
Before writing, grep the existing memory directory for the item's key terms. On a near-duplicate, update that file instead of adding a second. On a direct contradiction with an entry already on file ("use tabs" when "use spaces" is recorded), do not blind-append — surface both and let the user choose merge, replace, or keep-both. Silent duplicate and contradiction accumulation is the main way a curated memory index rots.
For each skill invoked during the session:
**A. Self-check gate** -- If the skill lacks success criteria + verification loop:
**B. Token efficiency** -- Flag: redundant phrasing, mergeable sections, oversized examples, "Claude already knows this" content, inert frontmatter metadata.
**C. Other** -- Missing edge cases, vague directives (rewrite as measurable criteria or remove), naked negations (add "do Y instead" or remove).
**D. Guidance mismatch** -- fires when a skill was invoked and its advice turned out wrong, stale, or inapplicable *here*. A, B, and C all judge a skill standing alone; this one anchors the finding to the line that actually misfired. Record four fields, all required:

A Claude Code plugin that makes AI coding agents follow engineering discipline. Plan before coding. Verify before claiming done. Find root cause before patching. Review before merge. Skills activate based on file type and task signals, not manual toggling.
