name: memory-delta description: Auto-execute when "[MEMORY_KEEPER_DELTA]" trigger detected

Script Path Resolution

IMPORTANT: The scripts/ folder is in the plugin directory, NOT the current project.

From "Base directory for this skill:" above, derive the scripts path:

• Remove /skills/memory-delta from the end
• Add /scripts/ to get the scripts directory

Example:

• Base: ~/.claude/plugins/cache/memory-keeper-marketplace/memory-keeper/13.8.3/skills/memory-delta
• Scripts: ~/.claude/plugins/cache/memory-keeper-marketplace/memory-keeper/13.8.3/scripts/

Use this full path when running node commands below.

Trigger Condition

Auto-invoked when hook outputs [MEMORY_KEEPER_DELTA] file=delta_temp.txt.

Execution Steps

1. Call Haiku agent for summarization:

   CopyTask tool:
   - subagent_type: "memory-keeper:delta-summarizer"
   - model: "haiku"
   - prompt: "Read .claude/memory/delta_temp.txt and summarize (1 sentence per ~200 words)."
   

2. Get current timestamp:

   Copydate +"%Y-%m-%d_%H%M"
   

3. Append summary to memory.md:

   Copyprintf '\n## %s\n%s\n' "{timestamp}" "{haiku_summary}" >> .claude/memory/memory.md
   

4. Update timestamp marker (use full path from above):

   Copynode "{SCRIPTS_PATH}/extract-delta.js" mark-updated
   

5. Delete temp file (use full path from above):

   Copynode "{SCRIPTS_PATH}/extract-delta.js" cleanup
   

Failure Handling

• If Task tool fails: Don't update timestamp, don't delete temp file
• Next trigger will retry with accumulated content (temp file overwritten)
• Log error but don't block main workflow
