Editorial interest 77/100 Selection signal · not a rating of the site

A shell-installable skill that uses ratings, tests, or other scores to guide small edits to AI-agent skills.

Landing page captured for the 2026-10-05 issue.

For: People tuning skills for shell-capable AI agents
Worth noticing: The test-count example ranks results against the last 50 runs, so differing test-suite sizes can be compared, according to the page.

Field notes

The installation command is `npx skills add AvdMei/learnabolic`; the page lists Claude Code, Codex, Cursor, or any agent that can run shell commands, with Node 20 or later. Users can supply a 0–10 rating, thumbs-up/down, test counts, timing, or another goal metric; for tests, the instructions add a scoring rule to `.learnabolic/bugfix/goals.md`. The page names Thompson, Q, SPRT, and CUSUM among its statistical instruments.
