mb-garden — Memory Bank maintenance (doc gardening)

• What it does: maintains Memory Bank docs, fixes hygiene issues, and keeps navigation coherent.
• Use it when: .memory-bank/ exists and you want to reduce drift, stale docs, or broken routing.
• Input: an existing .memory-bank/.
• Output: a cleaner Memory Bank, resolved hygiene issues, and optional CI support for ongoing maintenance.

Goal

Keep .memory-bank/ accurate, navigable, and cheap-to-prime. mb-garden owns maintenance and cleanup guidance. The current package also ships deterministic tool assets, but mb-lint and mb-doctor remain separate gates with separate roles.

Preconditions

• .memory-bank/ exists.

Process

1) Install deterministic maintenance tools

If the repo doesn’t have the tools yet: 1) Create scripts/mb-lint.mjs using assets/mb-lint.mjs. 2) Create scripts/mb-doctor.mjs using assets/mb-doctor.mjs. 3) Make them executable (optional). 4) Add package scripts (optional): "mb:lint": "node scripts/mb-lint.mjs" and "mb:doctor": "node scripts/mb-doctor.mjs".

Current package location includes both tool assets under mb-garden/assets; this is a packaging detail, not conceptual ownership of the doctor readiness role.

Then run:

node scripts/mb-lint.mjs
node scripts/mb-doctor.mjs

Fix all ERROR findings:

• missing YAML frontmatter (description + status)
• broken links
• missing folder index.md
• invalid or missing schema-backed task records, including missing/invalid mandatory tier
• obsolete .memory-bank/tasks/backlog.md or markdown task cards used as workflow state
• old risk / risk.level task fields; task routing is only by task.tier

mb-lint is the structural/mechanical hygiene gate. mb-doctor is the workflow/autonomous readiness gate over mb-lint. Default mb-doctor is suitable for normal health checks and fresh skeletons. Run strict mode only after the JSON task queue exists: after /prd-to-tasks, before scheduler execution inside /autonomous, or before /autopilot when the queue is already prepared:

node scripts/mb-lint.mjs
node scripts/mb-doctor.mjs --strict

Do not treat strict mode as required for a bare generated skeleton with an empty task registry.

2) Refactor for ergonomics

• Split docs > ~700 lines into atomic docs + router index.
• Ensure key concepts are covered either by classic duo docs (architecture WHAT/WHY + guides HOW) or by equivalent spec-driven support docs.
• Replace copy-pasted code/config with links to source.

3) Archive stale or superseded docs

• Move outdated docs to .memory-bank/archive/.
• Leave a short tombstone stub in the original location with a link to the archive.

4) Optional: add CI gate

If the repo uses GitHub Actions:

• Create .github/workflows/memory-bank-lint.yml from assets/memory-bank-lint.yml.

5) Produce a short report

Write a summary (what changed + what remains) to:

• .tasks/TASK-MB-GARDEN/TASK-MB-GARDEN-S-01-final-report-docs-01.md

6) Weekly maintenance checklist

Run this checklist weekly (or every 5–10 meaningful changes):

1. Frontmatter audit: every .memory-bank/**/*.md has description + status.
2. Stale docs: scan for docs not updated in >2 weeks — archive or refresh.
3. Concept coverage check: every key concept is covered either by a matching architecture/<X>.md + guides/<X>.md pair or by clearly routed equivalent spec-driven support docs.
4. RTM sync: requirements.md RTM matches actual feature/test status.
5. Task record hygiene: completed tasks marked done in .task.json, every task has tier, and no orphaned tasks exist without a feature link.
6. Changelog: .memory-bank/changelog.md has entries for recent changes.
7. Index links: all links in index.md and router-indexes resolve correctly.
8. Archive tombstones: every doc in archive/ has a tombstone stub at original location.

Definition of done

• node scripts/mb-lint.mjs passes (0 errors).
• node scripts/mb-doctor.mjs readiness gate passes in default mode; --strict passes post-queue before scheduler/autopilot execution.
• Index navigation is coherent.
• No obvious duplication or stale docs without archive.
• Weekly checklist items are addressed.
