Individual skill
self-improve
Extract lessons from the current session, or sweep the project's past sessions when asked, and route them to the appropriate knowledge layer (project AGENTS.md, auto memory, existing skills, or new skills). Use when the user asks to "self-improve", "distill this session", "distill past sessions", "sweep past sessions", "extract lessons from all sessions", "save learnings", "update AGENTS.md with what we learned", "capture session insights", "remember this for next time", "extract lessons", "update skills from session", or "what did we learn".

# Self-Improve
Review the current conversation, or the project's past sessions when asked, to extract durable lessons and route each one to the right knowledge layer.
## Step 1: Detect Context
Available destinations:
- **Project AGENTS.md** — the instruction file in the project root, plus any nested ones in subdirectories. At each level use `AGENTS.override.md` when one is present, otherwise `AGENTS.md`: an override replaces that directory's `AGENTS.md` rather than adding to it, so a lesson written to a shadowed file never loads. A nested file scopes its guidance to that subtree, so a lesson scoped to one subtree belongs in the nearest enclosing file, with the root reserved for project-wide rules.
- **Auto memory** — one writable memory target resolved for the canonical project root. Prefer a synced Claude Code project-memory source, then a memory-update target explicitly named by the active harness. If neither resolves, skip this destination.
- **Skills** — Project skills at `.agents/skills/` (walked from project root down to cwd) and user-installed skills at `~/.agents/skills/` (resolve symlinks)
Resolve the canonical project root as the Git top-level containing the working directory, or the physical working directory outside a repository. Resolve Auto memory in this order:
