Skill Memory

Execution Modes

All non-task modes flow through: Content Mapping -> Memory Search -> Memory Operations

Content Mapping

Content mapping is the intermediate representation between input acquisition and memory operations. It segments input into topic-aligned chunks that can be matched against existing memories.

Content Map Data Structure

{
  "source": {
    "type": "text|file|directory",
    "path": "/path/to/input",
    "total_tokens": 2500
  },
  "segments": [
    {
      "id": "seg-001",
      "topic": "neovim/plugins/telescope",
      "source_file": "/path/to/file.md",
      "source_lines": "15-42",
      "summary": "Telescope custom picker creation pattern",
      "estimated_tokens": 350,
      "key_terms": ["telescope", "picker", "finders", "sorters", "attach_mappings"]
    }
  ]
}

Field Descriptions

Segmentation Algorithms

Structured Files (Markdown)

Split at heading boundaries:

1. Identify all headings (# ## ### ####)
2. Each heading starts a new segment
3. Segment includes all content until next same-or-higher level heading
4. Top-level content before first heading becomes its own segment

Structured Files (Code)

Split at blank-line-separated blocks:

1. Identify function/class definitions
2. Group related comments with their definitions
3. Separate standalone comment blocks as documentation segments
4. Keep import/require blocks together

Unstructured Text

Split at paragraph boundaries with topic grouping:

1. Split at double-newline (paragraph boundaries)
2. Group adjacent paragraphs with keyword overlap >40%
3. Single-sentence paragraphs merge with adjacent

Directory Input

Each file becomes an initial segment, then large files are split:

1. Each file is an initial segment
2. Files >800 tokens are split at section boundaries
3. Files <100 tokens are candidates for merging with related files

Small-Input Bypass

Inputs under 500 tokens skip segmentation and become a single segment:

if total_tokens < 500:
  segments = [{
    "id": "seg-001",
    "topic": inferred_topic,
    "summary": first_line_or_60_chars,
    "estimated_tokens": total_tokens,
    "key_terms": extract_keywords(content, 5)
  }]

Segment Size Guidelines

Key Term Extraction

Extract 3-5 significant terms per segment:

1. Remove stop words (the, a, is, are, etc.)
2. Extract nouns and technical terms (>4 characters)
3. Prioritize: proper nouns > technical terms > common nouns
4. Deduplicate (case-insensitive)
5. Return top 5 by frequency within segment

Memory Search

After content mapping, each segment is matched against existing memories to determine the appropriate operation (UPDATE, EXTEND, or CREATE).

MCP Search Path

When MCP server is available, use the execute pattern:

For each segment in content_map.segments:
  query = segment.key_terms.join(" ")
  results = execute("search", {
    "query": query,
    "vault": ".memory",
    "limit": 5
  })

Grep Fallback Path

When MCP is unavailable, use keyword-based file search:

# For each segment
for keyword in $key_terms; do
  grep -l -i "$keyword" .memory/10-Memories/*.md 2>/dev/null
done | sort | uniq -c | sort -rn | head -5

Overlap Scoring

Score keyword overlap between segment and each matching memory:

overlap_score = |segment_terms intersect memory_terms| / |segment_terms|

Where:
- segment_terms = segment.key_terms
- memory_terms = keywords extracted from memory content (same algorithm)

Classification Thresholds

Search Result Presentation -- MANDATORY STOP

YOU MUST call AskUserQuestion for EACH segment before writing anything. Do NOT infer what the user wants. Do NOT skip segments. Do NOT write memory files without explicit user confirmation per segment.

Present each segment with related memories via AskUserQuestion:

Segment: {segment.summary}
Topic: {segment.topic}
Key terms: {segment.key_terms.join(", ")}

Related Memories:
1. MEM-telescope-custom-pickers (72% overlap) -> Recommended: UPDATE
2. MEM-neovim-plugin-patterns (45% overlap) -> Recommended: EXTEND
3. MEM-lua-module-structure (18% overlap) -> Recommended: CREATE (no strong match)

What would you like to do with this segment?
[ ] UPDATE MEM-telescope-custom-pickers (replace content)
[ ] EXTEND MEM-neovim-plugin-patterns (append section)
[ ] CREATE new memory
[ ] SKIP - don't save this segment

Interactive Override

Users can override any recommendation:

• Change UPDATE to CREATE (preserve existing, create duplicate)
• Change EXTEND to UPDATE (replace instead of append)
• Skip any segment
• Merge segments before processing (combine into single memory)

Memory Operations

Three distinct operations for memory management:

UPDATE Operation

Replace memory content while preserving structure:

1. Read existing memory file
2. Preserve frontmatter: created (original), tags, topic
3. Update frontmatter: modified = today
4. Move current content to ## History section with date marker
5. Replace main content with new segment content
6. Preserve ## Connections section
7. Write updated memory
