▌
Reflect · ckorhonen bundle
Review a work session, transcript, or tool-call log and compound the learnings into durable improvements: agent rules (AGENTS.md/CLAUDE.md), new or updated skills, slash commands, deterministic scripts, sub-agent delegation, and context-bloat reduction. Use when the user says "reflect", at the end of a work session, on a schedule, or when asked how to make the agent faster, cheaper, or more reliable in this project. Do not use for ordinary code review unless the requested output is agent/process improvement.

▌
Reflect Memory · ckorhonen
Lifecycle maintenance for accumulated agent memory: dedupe, merge, expire, and resolve contradictions across AGENTS.md/CLAUDE.md agent rules, .reflect/ state, and other agent instruction files reflect maintains. Use monthly, when instruction files feel bloated or contradictory, when the agent cites stale rules, or after many reflect runs have accumulated. Not for extracting new learnings — that is the reflect skill.

▌
Reflect Skills · ckorhonen bundle
Scan local agent session logs (Claude Code, Codex) across many sessions, cluster the common failure and friction patterns, then manage the skill portfolio to address them: find and install existing ecosystem skills, create or modify local skills, fix under- or over-triggering descriptions, and remove skills that misfire. Use when the user asks to scan session logs for failure patterns, audit or tune their skills, or asks why a skill never fires. For single-session extraction use reflect instead.

installs
▌
Reflect Feedback · ckorhonen
Audit whether past reflect improvements are actually working. Reads the .reflect/applied.md ledger and checks each applied rule, skill, command, or script for evidence it fired and helped; grades entries verified, unused, or regressed, and prunes dead weight. Use on a schedule (weekly or every ~10 sessions), when the user asks "are these improvements working?", or before a reflect-memory consolidation pass. Requires prior reflect runs — if no .reflect/ ledger exists, run reflect first.
