+description: >
+   Audit and compact memory/MEMORY.md by removing superseded, duplicated, overly detailed, 
+   or ephemeral entries, and merging related items within a subsection. 
+   Runs interactively by default; use auto mode for unattended execution.
+---
+
+# compact-memory
+
+Compact `memory/MEMORY.md` when it grows too large or stale. The skill reads `memory/MEMORY.md` plus `USER.md`, `SOUL.md`, and `keep.md` (all three in the workspace root) to detect duplicates and outdated context, but only edits `memory/MEMORY.md`.
+
+## When to use
+
+- User says "compact memory", "clean up MEMORY.md", "memory audit", or similar.
+- `MEMORY.md` exceeds ~250 lines.
+- There are obvious duplicates between `MEMORY.md` and other memory files.
+- Old project notes, ephemeral debugging details, or superseded facts accumulate.
+
+The line threshold is only a proactive trigger. When the user invokes the skill explicitly, run the full audit regardless of line count.
+
+## Modes
+
+### Interactive mode (default)
+
+1. Read `memory/MEMORY.md`, and — for duplicate detection — also `USER.md`, `SOUL.md`, and `keep.md` (all three in the workspace root).
+2. Count total lines (`wc -l memory/MEMORY.md`). If the skill was **not** invoked explicitly by the user, the file is ≤ 250 lines, and there is no obvious staleness, report "nothing to clean up" and stop. When invoked explicitly, always continue to the audit.
+3. Identify candidates:
+   - **superseded** — replaced by newer facts or no longer relevant.
+   - **detail** — concrete commands, flags, paths, or measurements that belong in a skill or `results/` file.
+   - **duplicate** — same fact already present in `USER.md`, `SOUL.md`, or `keep.md`.
+   - **ephemeral** — one-off debugging, temporary state, or resolved incident details.
+4. Identify merge candidates within the same `###` subsection — related bullets that can be combined into one concise bullet.
+5. Present a numbered proposal in chat:
+   - list each delete with reason and original text;
+   - list each merge with merged text.
+   - Kept items are not listed.
+6. Wait for user approval. Accept commands like:
+   - `apply` / `ok` / `yes` — apply all proposed changes.
+   - `keep 3, 7, 12` — keep listed items, apply the rest.
+   - `delete 2, 5` — delete only listed items.
+   - `cancel` — abort.
+7. Apply approved changes to `memory/MEMORY.md`.
+8. Append deleted items to `log/memory-clean.log` with timestamp `YYYY-MM-DD HH:MM` (create the file if it does not exist).
+9. Report summary.
+
+### Auto mode
+
+Triggered by the user saying "memory-compact auto" or an equivalent with explicit auto intent.
+
+1. Perform the same audit as interactive mode.
+2. Before deleting anything, write a full snapshot of `MEMORY.md` to `backup/<YYYY-MM-DD_HHMM>_memory.backup.md`.
+3. Apply changes immediately without waiting for approval.
+4. Print a detailed list of changes.
+5. Append deleted items to `log/memory-clean.log` (create the file if it does not exist).
+
+## Rules
+
+- Only edit `memory/MEMORY.md`.
+- Do not touch `SOUL.md`, `USER.md`, or `keep.md`.
+- In interactive mode do not create backups of `MEMORY.md`; rely on `log/memory-clean.log` for traceability. Auto mode always writes a full snapshot to `backup/` before deleting.
+- Merge only within the same `###` subsection (never across `##` sections or across different `###` subsections).
+- Preserve active project context, user preferences, and infrastructure facts.
+- When in doubt, keep it and mention the uncertainty in the report.

+Interactive proposal:
+
+```
+Found X candidates to change in MEMORY.md:
+
+Delete:
+1. [superseded] <text>
+2. [detail] <text>
+...
+
+Merge:
+5 + 6: <merged text>
+...
+
+Commands: apply | keep <numbers> | delete <numbers> | cancel
+```
+
+Auto mode report:
+
+```
+Memory compact (auto):
+- deleted: X

+## Example
+
+User: `compact memory`
+
+Agent: reads files, counts lines, proposes changes, waits for `apply`.
