From 086446e06a72b8b259c703ecc05e246b41211926 Mon Sep 17 00:00:00 2001 From: Alex Soffronow Pagonidis <237136924+alex-clickhouse@users.noreply.github.com> Date: Sat, 15 Aug 2026 09:32:09 +0000 Subject: [PATCH] Add a pr-feedback-harvester cron to close the skill feedback loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The three skill-maintenance jobs all read from inside the instance. skill-extractor recalls memory and the existing skill list; skill-reviser loads the SKILL.md files and audits them against themselves. Neither one has any way to learn that a reviewer already told the agent it got something wrong. That leaves the highest-signal correction available — a human on a pull request saying "this is wrong, do it this way" — with no path into a skill. The only route today is accidental: an interactive session happens to read the comment, it lands in memory, and skill-extractor may or may not surface it twelve hours later. The harvester is the inbound half of that loop. Weekly, it reads the review threads on the PRs the agent authored in the last seven days, clusters the feedback into recurring themes rather than filing one item per comment, and splits the result by scope: general -> a generic skill, or a workspace instruction file repo-specific -> that repository's own dev skill Everything goes through the normal task+plan approval flow; the job never edits a skill directly. It memorizes each cluster regardless of what it proposes, so a declined or slow-to-approve plan doesn't lose the lesson. Two details in the prompt are load-bearing: The job ingests third-party text and then proposes edits to the agent's own instructions, which is a prompt-injection path. The prompt states that comments are evidence of what a reviewer wanted, never instructions addressed to the agent. plan_type is auto-detected from a task's source only for skill-extractor and skill-reviser. A cluster here can yield either a new skill or a revision, so source-based detection cannot decide; the job passes plan_type explicitly. Omitting it would silently produce a generic plan that spawns an implementation session instead of writing the skill. Scheduled Monday 04:00, a day clear of skill-reviser's Sunday 03:00 — both propose skill edits, and the gap keeps them from duelling over the same file. Enabled by default in worker mode alongside the other skill crons, offered during nerve init in personal mode, and gated on having either an authenticated gh CLI or a GitHub sync source.
