description	Human-led curation of accumulated metis and guardrails. Surface patterns across sessions, propose what to promote, compact, or dismiss. Use after multiple sessions, before a new phase, or when search results feel noisy.

/distill

Surface patterns in accumulated knowledge. Propose what to keep, promote, compact, or dismiss. The human decides.

Distill is the complement to /salvage: salvage extracts learning from a single session; distill curates the corpus those extractions build over time. Without distill, metis accumulates but never compounds.

When to Use

Invoke /distill when:

• After multiple sessions - The corpus has grown and hasn't been reviewed
• Before a new phase - Want to know what's actually settled before moving forward
• Search results feel noisy - oh_search_context returning too much loosely-related content
• Similar learnings keep appearing - /salvage keeps extracting the same insights (the meta-signal)
• End of a successful session - Even good sessions produce learnings worth capturing before context is lost

Use distill (not /salvage) when the session went well. /salvage is for stopping because things went wrong. Distill is for pausing because things went right — or simply finished — and learnings are worth capturing before context is lost.

Do not use when: You're in the middle of execution. Distill is a pause point, not a mid-flight activity.

The Human-Led Curation Principle

Distill leverages LLMs for what they're good at — pattern recognition, clustering, surfacing similar entries — while keeping judgment with the human.

LLMs do: find recurring themes, group similar entries, surface candidates. Humans do: decide what matters, what's worth promoting, what's stale or context-specific.

Auto-promotion is never correct. A theme proposal is not a guardrail until a human writes it.

The Process

Step 1: Establish Scope

Decide what corpus to work with:

• Session scope (default, no RNA needed): learnings from this conversation
• Corpus scope (RNA available): accumulated metis across all sessions, optionally filtered by outcome, phase, or tag

Step 2: Surface Candidates

Session scope: Review the conversation. What was learned? What assumptions were validated or invalidated? What constraints were discovered? What would be useful to know at the start of the next session?

Corpus scope (RNA): Call oh_search_context broadly. Cluster by semantic similarity. Identify:

• Entries that appear together repeatedly (candidates for compaction)
• Patterns across entries (candidates for guardrail promotion)
• Entries that contradict each other (candidates for resolution)
• Entries that are stale or overly context-specific (candidates for dismissal)

Step 3: Present for Human Review

Present each candidate group with four possible actions:

**Theme: [theme name]**
Entries: [list with source IDs and one-line summaries]
Suggested action: [Keep / Promote / Compact / Dismiss]
Reason: [why this action fits]
→ Your call:

Keep — leave as individual metis entries, no change. Promote — pattern is recurring and stable enough to warrant a guardrail. Distill drafts a stub; human approves the content (editing as needed), then an agent writes the file:

---
id: [slug]
outcome: [outcome-id]
severity: soft
title: [one-line constraint]
---
[drafted body — human refines, agent writes to .oh/guardrails/]

Compact — multiple entries say the same thing. Human approves a merged version; originals archived or deleted. Dismiss — stale, superseded, or so context-specific it misleads more than it helps.

Step 4: Write Results

Only write what the human approved. No auto-promotion, no auto-deletion.

• New metis entries → .oh/metis/<slug>.md
• Guardrail candidates → draft for human to write to .oh/guardrails/<slug>.md
• Compactions → new merged entry + note which originals can be removed
• Session file compaction → offer to remove stale planning artifacts, keep settled decisions as brief anchors

Output Format

## Distill Summary

**Scope:** [session | corpus — filtered by: outcome/phase/tag]
**Entries reviewed:** [N]

### Proposals

**[Theme or entry title]**
- Source(s): [file paths or conversation reference]
- Suggested: [Keep / Promote to guardrail / Compact / Dismiss]
- Reason: [one sentence]
→ Decision: [human fills this in]

[repeat for each proposal]

### Results Written
- [what was actually written, with file paths]

Guardrails

• Never auto-promote. A theme proposal is not a guardrail until a human writes it.
• Never auto-delete. Dismissal proposals require human confirmation.
• Preserve provenance. Every proposal links to source metis IDs or conversation context.
• Phase-aware. Corpus-mode clustering must surface phase tags — cross-phase metis often misleads. A solution-space learning is not automatically relevant in problem-space.
• Graceful with sparse corpus. With fewer than 5 entries, surface what exists without manufacturing false patterns. Don't cluster noise.
• Metis is contextual, not universal. What worked in one context doesn't carry everywhere. The human selects what applies; distill surfaces candidates.

Adaptive Enhancement

Base Skill (prompt only)

Reads the current conversation. Surfaces what was learned this session. Proposes metis entries for human review and approval. Works after any completed session — the positive complement to /salvage (which is for drift and failure).

Output: approved entries as markdown, ready to write to .oh/metis/.

With .oh/ session file

• Reads .oh/<session>.md for session context and prior metis
• Writes approved metis entries directly to .oh/metis/
• After distill, offers to compact the session file itself: remove stale planning content, keep settled decisions as brief anchors
• The compacted session file seeds future sessions more cleanly

With RNA MCP (repo-native-alignment)

Corpus mode: oh_search_context across all accumulated metis (or filtered subset), cluster by semantic similarity, surface candidate groups for human review.

Output is PR-able: distill produces a set of proposed file writes (new guardrail stubs, compacted metis, removal notes) formatted as a markdown summary. The human creates a branch, writes the approved files, and opens a PR — or uses /oh-plan to create issues for each promotion. Curation becomes a collaborative act, not a solo one.

Filtering options: pass outcome ID, phase tag, or recency window to oh_search_context to narrow the corpus. Useful when the full corpus is large but only a domain slice needs curation.

Position in Framework

Comes after: Multiple sessions of /salvage or /execute that have accumulated metis. Or: end of any session where learnings are worth capturing before context is lost. Leads to: Cleaner oh_search_context results. Guardrail candidates for human authoring. A compacted session file that seeds the next session. Relationship to /salvage: Salvage is per-session extraction (especially from failure). Distill is corpus-level curation (independent of any single session outcome). They're complementary — salvage feeds the corpus; distill keeps it from becoming noise.

Leads To

After distill, typically:

• Write approved guardrail files to .oh/guardrails/
• Open a PR with .oh/ changes for team review (corpus mode)
• Return to /aim or /problem-space with a cleaner, more settled context

Remember: Distill is not synthesis. The LLM finds patterns; you decide what matters. A corpus that accumulates without curation becomes noise. A corpus that's periodically distilled becomes situated judgment — the kind that actually improves future sessions.
