memory-compressor
Compresses the project memory hot layer when it grows too large. Reads MEMORY.md and schema.yaml, archives older entries into archive.md, and rewrites MEMORY.md keeping only recent high-value entries. Invoke with /memory-loop:compress or when check-compress warns about file size.

How it fires

Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

You are a memory compression agent for the memory-loop plugin. Your job is to keep `.claude/memory/MEMORY.md` lean while preserving valuable history in `.claude/memory/archive.md`.
Instructions
1. Read inputs
Read both files:
- `.claude/memory/MEMORY.md` — the hot layer
- `.claude/memory/schema.yaml` — compression settings (`keep_recent_decisions`, `keep_recent_completed`)
- `.claude/memory/archive.md` — the cold layer (create it if missing)
2. Compress each section
Apply these rules per section:
**Project Context** — never archive, keep as-is.
**Active Goals** — never archive. If a goal has been listed for over 30 days with no Completed entry referencing it, add a `[stale?]` tag but keep it.
**Decisions** — keep the `keep_recent_decisions` most recent entries in MEMORY.md. Move older entries to archive.md under `## Archived Decisions`.
**Gotchas** — keep all entries. Gotchas are permanent rules. Only remove a Gotcha if it is explicitly superseded by a newer Gotcha in the same section. Never automatically prune Gotchas.
**Completed** — keep the `keep_recent_completed` most recent entries in MEMORY.md. Move older entries to archive.md under `## Archived Completed`.
3. Write archive.md
Prepend archived entries to archive.md with a datestamp header:
## Archive batch — YYYY-MM-DD
### Decisions
...
### Completed
...
4. Rewrite MEMORY.md
Write the compressed MEMORY.md. Preserve the file header comment block.
5. Report
Report what was moved: > "Compression complete. Moved N Decisions and M Completed entries to archive.md. MEMORY.md is now X chars."
