From 4cd03e9fffc770554b43951efe975841e72b7d83 Mon Sep 17 00:00:00 2001 From: Hoang Snowy Date: Fri, 23 Oct 2026 08:16:02 +0700 Subject: [PATCH] feat(memory): a Retrospective agent turns lessons into project practices every agent follows MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Self-improvement, step two. After a ticket merges (MAF workflow or step by step), the Retrospective agent runs in the background on the member's computer: it reads the project's raw lessons (reviews, failing checks, failed acceptance) next to its current practices and returns the project's practices — at most 15 short, actionable, project-specific sentences — plus the lessons they now cover. - Knowledge graph: MemoryKinds.Practice (content-keyed), IMemoryStore.ListAsync(kind), ProjectMemory.PracticesBlock. - Readers: the Coding agent gets the practices before the closest lessons; the Reviewer checks the change against them (breaking one is a must-fix finding). - Guardrails (RetrospectiveService): once per project every 10 minutes, one at a time; pinned practices and lessons are never removed; only lessons the agent was shown can be cleared; an empty or failed answer changes nothing. The run is recorded in Insights; the Autopilot log says what changed. - Board › Knowledge: a Practices panel (pin to keep word for word, forget) above the lessons. - Insights › Delivery (#272) shows whether first-try passes go up.
