Description

Adds skills/superself/SKILL.md. Disclosure: I maintain Superself. It is a free, Apache-2.0, local-first CLI (npm install -g superself, no account or service) that version-controls a project's state — goals, decisions, work units, reports — as an append-only event log in a git repository separate from the code; self connect renders a managed block into AGENTS.md/CLAUDE.md and self context prints the derived context an agent reads at session start. The skill tells Copilot when the project uses Superself and how to drive the self CLI across a session: read context at start, attach work to a work unit, report with a commit as evidence, record confirmed decisions, and close a unit only with evidence. Every command in the skill is checked against the current CLI help. npm run skill:validate passes (413 skills valid) and npm start regenerated docs/README.skills.md with one new row; nothing else changed.
