Look back over a session and suggest changes to the agent's environment — navigation pointers, automated checks, coding standards, steering files, tooling — so the next run starts from a better place. Apply nothing until the user picks.

Steps

1. Read the session. Default: this one, before /clear. An earlier session ($ARGUMENTS) lives at ~/.claude/projects/<cwd with / as ->/<session-id>.jsonl. Redact secrets when you quote it.
2. Read the environment first: CLAUDE.md / AGENTS.md (repo and global), CODING_STANDARDS.md, the repo's own lint / typecheck / test commands, pre-commit hooks, CI workflows.
3. Find candidates in every category below. Completion: each category has a candidate or "nothing found".
4. Present them most severe first, each with its session evidence (what happened, where) and the proposed change. Apply only what the user picks. Before drafting steering text, call the Skill tool with create-skill for its Writing style: the no-op test, prompt the positive.
