Distill

Take a completed research thread, brainstorming topic, or recurring theme and compress it into a single, structured knowledge note. Unlike /wrapup (session-focused), /distill is topic-focused and spans multiple sessions.

Usage: /distill [topic]

Step 1: Identify the Topic

If a topic was provided after the command, use it directly. If not, ask:

What topic do you want to distill? (e.g. "OneBrain memory architecture", "Mac Mini purchase decision", "MCP server setup")

Step 2: Gather Source Material

Search across the vault for notes related to the topic. Use 2–3 specific keywords or phrases from the topic (prefer proper nouns and multi-word phrases over generic single words):

Use qmd if available for content searches; Grep/Glob as fallback.

1. Session logs: Search [logs_folder]/**/*.md for topic keywords — extract matching ## Key Decisions, ## Action Items, ## Open Questions sections
2. Inbox: Search [inbox_folder]/*.md for related content
3. memory/ files: Search [agent_folder]/memory/ for related entries — match topic keywords against filename and frontmatter topics: field
4. Project/knowledge notes: Search [projects_folder]/**/*.md, [knowledge_folder]/**/*.md, and [resources_folder]/**/*.md — filter by note title or first 100 words

Report to user (N = total matches across all sources; Q = project/knowledge/resource notes combined): Found {N} sources: {M} session logs, {P} inbox notes, {Q} knowledge notes

If N = 0: Stop and inform the user: 🔴 No notes found matching '{topic}'. Try a broader keyword or check the topic name.

Exit — do not proceed to Step 3.

If N > 20: Too many results — the keywords may be too broad. Use AskUserQuestion:

Found N sources for '[topic]' — that's a lot. Do you want to:

1. Narrow the scope (I'll ask for more specific keywords or a date range)
2. Continue with all N sources

If user picks option 1, call AskUserQuestion immediately (do not wait or proceed):

Please provide more specific keywords or a date range (e.g. "focus on MCP setup decisions from March 2026"):

Use the user's answer as refined search criteria and re-run the search from the top of Step 2. If the refined search still returns > 20 sources, inform the user and proceed with all N rather than asking again (one clarification cycle maximum). If user picks option 2 (continue with all N), proceed.

Step 3: Synthesize

Extract and consolidate across all sources:

• Core question — what was being explored or decided?
• What we found — key findings, facts, conclusions
• Key decisions made — explicit choices that were committed to
• Lessons — generalizable insights worth keeping long-term
• Open questions — still unresolved as of the most recent source
• Entities involved — tools, projects, people mentioned

Present a brief synthesis preview to the user before writing.

Step 4: Choose Destination

Suggest a subfolder in [knowledge_folder]/:

• Infer topic category (e.g. "OneBrain memory architecture" → [knowledge_folder]/ai-systems/)
• Present to user using AskUserQuestion: "I'd file this under [knowledge_folder]/[suggested-path]/. OK, or would you like a different path?"
• If user declines, ask for the preferred path or subfolder name before proceeding.
• If user cancels entirely, offer one more option via AskUserQuestion: "Save a draft to [inbox_folder]/YYYY-MM-DD-[topic]-draft.md instead?" If yes, save the Step 4 synthesis there. If no, discard.
• Use the confirmed path for file creation.

Step 5: Write the Digest Note

Before writing: Check if [knowledge_folder]/[subfolder]/[Topic].md already exists.

• If the file does not exist: create it.

• If the file already exists: use AskUserQuestion to ask:

  A distilled note for "[Topic]" already exists. How do you want to handle this?

  1. Overwrite — replace with a fresh synthesis
  2. Append — add a ## Update — YYYY-MM-DD section with new findings
  3. Cancel

  If Append is chosen: before writing new content, read the existing digest note and check for any lessons that appear hedged or uncertain in phrasing (e.g. "might", "possibly", "unclear if", or legacy [conf:low] markers). If any exist, surface them:

  This note has M low-confidence lessons. Want to re-evaluate any before appending? (list them) User may promote or leave them as-is. If none exist, skip this silently and proceed to append.

  If Overwrite is chosen: read the existing file first to extract its created: date — this marks when the topic was first distilled and must be preserved. If no created: field exists in the file, use the file's filesystem modification date as a best-effort fallback; if that is also unavailable, use today's date and note the uncertainty in sources_span. Update sources_span to span from the original start date to today's date.

Create or update [knowledge_folder]/[subfolder]/[Topic].md:

Step 6: Update qmd Index

If qmd_collection is set in vault.yml, run:

bash
1qmd update -c [qmd_collection]
