Assess whether the .gir/ memory bank is stale and recommend what to update.

---

Instructions

Follow these steps in order:

Step 1: Check if .gir/CLAUDE-activeContext.md exists

Check whether .gir/CLAUDE-activeContext.md exists in the current project directory.

If it does not exist, respond with:

No memory bank found.

.gir/CLAUDE-activeContext.md does not exist in this directory.

To set up a memory bank, run:
  /gir-core:init-memory-bank

The memory bank helps Claude restore context at the start of each session and track decisions, patterns, and known issues across sessions.

Then stop — do not proceed further.

If it does exist, continue to Step 2.

Step 2: Scan all memory bank files

Check which of the following files exist in .gir/:

• CLAUDE-activeContext.md
• CLAUDE-decisions.md
• CLAUDE-patterns.md
• CLAUDE-resources.md
• CLAUDE-troubleshooting.md

For each file that exists, read it.

Step 3: Assess freshness

For each file that exists, determine its freshness:

For CLAUDE-activeContext.md:

• Look for a "Last Updated" date/time field near the top
• If it has a date: calculate how long ago that was relative to today
• If it has no date or only placeholder text ([Date/Time]): mark as "never updated"
• Check if "Current Goals", "In Progress", and "Next Steps" sections have real content or still contain template placeholders

For CLAUDE-decisions.md:

• Check if any real decision entries exist (look for actual dates in ### [YYYY-MM-DD] headings)
• If the file only contains the template placeholder entry, mark as "empty"

For CLAUDE-patterns.md:

• Check if the naming conventions, component patterns, or other sections have been filled in
• If sections still contain only template placeholder text, mark as "empty"

For CLAUDE-resources.md:

• Check if any real URLs have been added (look for actual https:// links beyond the template examples)
• If only placeholder URLs exist, mark as "empty"

For CLAUDE-troubleshooting.md:

• Check if any real issue entries exist
• If the file only contains the template structure with no real issues, mark as "empty"

Step 4: Show status report

Present a clean summary:

Memory Bank Status
------------------

Files present:
  [checkmark or X]  CLAUDE-activeContext.md    [status: e.g., "updated 3 days ago" | "never updated" | "has placeholder text"]
  [checkmark or X]  CLAUDE-decisions.md        [status: e.g., "2 decisions logged" | "empty (template only)"]
  [checkmark or X]  CLAUDE-patterns.md         [status: e.g., "partially filled" | "empty (template only)"]
  [checkmark or X]  CLAUDE-resources.md        [status: e.g., "3 URLs added" | "empty (template only)"]
  [checkmark or X]  CLAUDE-troubleshooting.md  [status: e.g., "1 issue documented" | "empty (template only)"]

Missing files (if any):
  [list any of the 5 files that do not exist]

Step 5: Provide specific recommendations

Based on what you found, suggest specific actions. Prioritize in this order:

1. activeContext — most critical; should be updated every session
2. patterns — important once the codebase has established conventions
3. decisions — important whenever architectural choices are made
4. troubleshooting — fill in as issues are encountered and resolved
5. resources — optional; add only if you rely on external references

Format recommendations as actionable items:

Recommendations
---------------

[Priority 1 — if activeContext is stale or empty]:
  CLAUDE-activeContext.md hasn't been updated recently.
  Update it now with:
  - Your current session goals
  - What's in progress
  - Any blockers or recent decisions

[Priority 2 — if patterns is empty]:
  CLAUDE-patterns.md is empty.
  As you develop conventions (naming, component structure, API patterns),
  document them here so Claude can follow them consistently.

[Priority 3 — if decisions is empty but the project seems mature]:
  No architectural decisions have been logged.
  If your project has made choices about state management, API design,
  database schema, etc., consider documenting the rationale in CLAUDE-decisions.md.

[If everything looks current]:
  Memory bank looks up to date. No urgent action needed.
  Consider reviewing CLAUDE-activeContext.md at the start of each new session.
