${var} - Topic to focus on. If empty, flushes all recent activity.

If ${var} is set, only promote entries related to that topic. Pruning (step 3), the index upkeep (step 6), and the deterministic watermark + rotation (steps 0 and 8) still run globally - a focused flush must never leave the rest of the store stale.

Read memory/MEMORY.md for current memory state. The scan window and log rotation are computed for you in step 0 - you no longer parse the watermark or rotate logs by hand.

Steps

0. Prepare (deterministic bookkeeping - run this first)

Run python3 scripts/memory_prep.py window and read its stdout. It:

• computes your scan window from the structured watermark memory/memory-flush-state.json (fallback for a first-run migration: the MEMORY.md *Last consolidated:* line; then the last 3 days; a gap over 14 days is clamped to 14 and flagged), and prints the exact in-window log files to read;
• has already rotated whole old months out of memory/logs/ into memory/logs/archive/YYYY-MM.md (content-preserving) once the directory passed ~45 files.

Read exactly the files it lists. Do not recompute the window or rotate logs yourself - that work is now deterministic and unit-tested (scripts/memory_prep.py), so it never silently falls back to 3 days or gets skipped. This closed two old holes: entries older than 3 days were lost whenever the agent skipped runs, and a daily schedule re-scanned the same 3 days every time.

1. Scan the in-window logs for entries worth promoting to long-term memory

• New lessons learned (errors encountered, workarounds found)
• Topics covered (articles, digests) - add to the recent output/articles/digests tables
• Features built or tools created
• Important findings from monitors (on-chain, GitHub, papers)
• Ideas captured that are still relevant
• Goals completed or progress milestones

2. Check each candidate against existing MEMORY.md content - dedup precisely

Skip if already recorded. Dedup by the fact's subject, not by string match:

• Identify what each candidate is about (a skill, a token, a repo, a lesson, a priority).
• If MEMORY.md already carries that subject, edit the existing line in place (merge the new detail, bump any date). Never append a second bullet that paraphrases an existing one - that near-duplicate drift is what a memory flush exists to prevent.
• Only add a new bullet when the subject is genuinely absent.

3. Remove stale entries - this is as important as adding new ones

a. Open Improvement PRs section: Run gh pr list --state open --search "improve:" --json number,title,url and compare against any "Open Improvement PRs" section in MEMORY.md.

• If all listed PRs are now merged/closed, remove the section entirely.
• If some PRs are merged, update the list to reflect only current open ones. b. Next Priorities section: Cross-check each listed priority against recent logs and current repo state. Remove priorities that are already done (e.g., "Merge open PRs" if 0 open PRs exist). Add any newly urgent priorities surfaced by recent logs. c. Lessons Learned: Remove lessons that are now outdated or resolved (e.g., a workaround for a bug that was later fixed). d. Overflow any section that outgrows its budget (keeps MEMORY.md an index, not a ledger): if a section has grown past the last ~10-15 rows - the Skills Built table is the usual first offender, but the rule is general - archive the oldest rows to memory/topics/<section>-history.md (e.g. skills-history.md) and leave a one-line pointer to that file. Trim newest-kept, oldest-archived.

4. Update memory

• Add brief entries to MEMORY.md (keep it under ~50 lines as an index).
• If a topic needs more detail, write to memory/topics/<topic>.md instead (see step 6 - register it in the index).
• Update tables (recent articles, recent digests) with new rows.
• Before adding a section, check whether its ## Heading already exists anywhere in MEMORY.md - if it does, update that section in place. Never prepend a duplicate heading.
• Do not hand-edit the consolidation date. It is stamped by step 8 (memory_prep.py stamp), which writes the structured watermark memory/memory-flush-state.json (the source of truth) and mirrors it into the MEMORY.md *Last consolidated:* line. Skipping step 8 after a real flush is a bug - other skills (e.g. action-converter) read that line to tell a live, consolidated store from an untouched template.

5. Make targeted edits only

Do NOT rewrite the whole file - make targeted additions and removals.

6. Register any new topic files in the index

If step 4 created a new memory/topics/<topic>.md (or a *-history.md archive in step 3d), add a one-line pointer to it under the # Reference section of memory/topics/index.md, matching the existing row format. New topic notes that aren't linked from the index become orphans no other run can find.

7. (Automated) Log rotation

Log rotation now runs deterministically in step 0 (memory_prep.py window): whole calendar months entirely older than the 14-day scan floor are appended to memory/logs/archive/YYYY-MM.md and git rm'd once memory/logs/ passes ~45 files. The archive preserves every line, respecting the append-only contract while bounding the file count. Nothing to do here by hand; a log inside the scan window is never touched.

8. Log the run, then stamp the watermark

Log what you promoted, pruned, and archived, plus the scan window you used (start date to today; note if a >14-day gap was clamped), to memory/logs/${today}.md.

Then run python3 scripts/memory_prep.py stamp as your final action - it writes today's date to memory/memory-flush-state.json and mirrors it into the MEMORY.md *Last consolidated:* line.

If nothing was worth promoting or removing, log MEMORY_FLUSH_OK - but still run memory_prep.py stamp: a clean flush is still a consolidation and must advance the watermark.

Network note

gh pr list uses the gh CLI's built-in auth - no curl env-var expansion. python3 scripts/memory_prep.py and all other work is local file I/O against memory/ (plus git rm for log rotation).

Constraints

• Keep MEMORY.md an index (~50 lines). Detail lives in memory/topics/.
• Never duplicate an existing ## Heading or an existing fact - update in place.
• Pruning stale entries is as important as adding new ones.
• The watermark and log rotation are owned by scripts/memory_prep.py (steps 0 and 8), not by hand. The model's job is judgment: what to promote, dedup, and prune.
• This skill owns MEMORY.md consolidation. Other skills (e.g. self-improve) may flag memory-hygiene problems, but structural pruning and archiving of MEMORY.md should land here to avoid two skills thrashing the same file. If self-improve prunes in an audit, treat it as a stopgap, not a reason to skip the next flush.
