# Second-Brain Distillation

## Trigger

Use when personal knowledge and agent collaboration must support ongoing projects, responsibilities, learning, or creative output across sessions.

## Inputs

Current projects, areas of responsibility, captured material, reusable resources, intended outputs, privacy boundaries, and existing personal tools.

## Procedure

1. Capture only material likely to support an outcome, responsibility, decision, learning path, or expression.
2. Organize views around active projects, ongoing areas, reusable resources, and a quiet archive.
3. Distill progressively: highlight relevance, summarize with source context, then promote only durable concepts.
4. Express knowledge through decisions, drafts, artifacts, explanations, or completed work.
5. Link personal material to projects and sources without presenting personal notes as institutional truth.
6. Process, promote, archive, or delete the capture queue; do not let capture become permanent clutter.
7. Review inactive projects and resources periodically and quiet them when they no longer affect action.

## Verification

- Every active item supports a project, area, decision, learning path, or output.
- Personal and institutional knowledge boundaries remain distinct.
- Captures do not accumulate without processing.
- Distillation preserves source and uncertainty.
- The system can remain incomplete and adapt incrementally.

## Failure Modes

- Designing a complete taxonomy before using the system.
- Collecting without processing or expression.
- Promoting private biography or temporary mood into durable actor ontology.
- Treating personal synthesis as authoritative project evidence.
- Keeping completed material in active retrieval paths forever.
