concept-synthesis — From Raw Stubs to Intellectual Map

Convention: see conventions/quality.md for back-link enforcement and quote-fidelity requirements.

Convention: see _brain-filing-rules.md — output files under concepts/ per the primary-subject rule.

What this solves

Many ingestion pipelines (signal-detector, idea-ingest, voice-note-ingest) create a concept page for every idea mentioned. Over months this produces:

• Thousands of stub pages, many duplicates or near-duplicates
• Timeline entries that repeat the same source across multiple concept pages
• No synthesis — just "the user mentioned X on this date"
• No tier assignments — everything flat
• No clustering — related ideas aren't linked

This skill transforms that raw material into a curated intellectual map.

Architecture

Phase 1: Dedup + merge (deterministic)
  N stubs → ~N/4 canonical concepts
    ├── Jaccard dedup (word-overlap on titles + first-paragraph)
    ├── Substring dedup ("founder mode" vs "founder mode vs manager mode")
    ├── Semantic dedup (LLM: "are these the same idea?")
    └── Merge timelines + aliases from duplicates into the canonical page

Phase 2: Score + tier (deterministic + heuristic)
  Each canonical concept → scored and tiered
    ├── Frequency: distinct sources referencing this concept
    ├── Timespan: first mention → last mention in days
    ├── Breadth: distinct months it appears in
    ├── Engagement: avg engagement on concept-bearing sources (if available)
    └── Tier: T1 Canon | T2 Developing | T3 Speculative | T4 Riff

Phase 3: Synthesize (LLM, T1+T2 only)
  T1 + T2 concepts → rich synthesis
    ├── Evolution narrative: how the idea sharpened over time
    ├── Best articulation: highest-engagement or most precise quote
    ├── Related concepts: cross-links to other concepts
    ├── Context: what was happening when this idea emerged / evolved
    └── Counter-positions: what this idea argues against

Phase 4: Cluster + map (LLM)
  All tiered concepts → intellectual clusters
    ├── Group related concepts into domains (auto-named via LLM)
    ├── Generate cluster summary pages
    ├── Build a master concepts/README.md with the full map
    └── Identify idea genealogies (concept A → evolved into concept B)

Invocation

The skill is markdown agent instructions. The agent uses gbrain's existing operations + LLM passes:

# 1. List all concept pages
gbrain query "type:concept" --limit 10000 --json

# 2. Phase 1 dedup — agent applies Jaccard + substring locally,
#    then LLM passes to identify semantic duplicates.

# 3. Phase 2 tier — agent scores each canonical concept based on
#    frequency / timespan / breadth and writes tier into frontmatter.

# 4. Phase 3 synthesis — for each T1/T2, agent reads the timeline
#    + associated source pages and writes a synthesis section
#    onto the concept page via put_page.

# 5. Phase 4 clustering — agent reads the tiered concept list
#    and writes concepts/README.md with the full intellectual map.

Output: concept page format (post-synthesis)

# concept name

**Tier 1 — Canon** | 18 mentions across 8 months

## Synthesis

[2-4 paragraph narrative tracing how the idea evolved, what it means in
the user's worldview, why it matters. Third-person analytical voice.]

## Best Articulation

> "Verbatim quote from a source — the most precise or highest-engagement
> expression of this idea." — [Date](source-url)

## Evolution

| Period | Expression | Signal |
|--------|-----------|--------|
| YYYY-MM | "First articulation" | First use — aspiration frame |
| YYYY-MM | "Sharpening" | Anti-pattern emerges |
| YYYY-MM | "Peak form" | Cleanest expression |

# Intellectual Universe

## Canon (T1) — N concepts
The permanent intellectual fingerprint. Ideas that recur across years.

### [Cluster Name]
- [concept-slug](concept-slug.md) — one-line characterization
- ...

### [Other Cluster]
- ...

## Developing (T2) — N concepts
Sharpening. Might become canon.

## Speculative (T3) — N concepts
Testing in public.

## Stats
- Total concepts: N
- T1 Canon: N
- T2 Developing: N
- T3 Speculative: N
- T4 Riff: N
- Earliest source: YYYY-MM-DD
- Latest source: YYYY-MM-DD

Quality gates

Dedup quality

• No two concept pages should be "the same idea in different words."
• Aliases preserved in frontmatter for search.
• Run gbrain query "type:concept" and spot-check the count reduction.

Tier quality

• T1 should feel like "yes, that IS one of my recurring frameworks" — recognizable, recurring, sharp.
• T2 should feel like "I'm working on this; it's getting clearer."
• No concept should be T1 with < 4 months span or < 6 mentions.
• No concept should be T4 with > 3 months span.

Synthesis quality

• Captures evolution, not just repetition.
• Uses verbatim quotes, not paraphrase.
• Links to related concepts (markdown links, not wiki-links).
• Does NOT hallucinate sources or dates.

Cron integration

This is heavy work. Run on a cadence, not on every signal:

• After a major ingestion batch completes (signal-detector burst, archive crawler run, etc.).
• Weekly cron for incremental synthesis of newly-promoted T1/T2 concepts.
• Manual trigger for a full re-synthesis when the corpus shifts significantly.

Anti-Patterns

• ❌ Running synthesis on T3/T4 — wastes API budget on ideas that may never sharpen.
• ❌ Hallucinating quotes or dates. The timeline must be verifiable against existing brain pages.
• ❌ Generic cluster names ("Various Topics"). If you can't name the cluster, the cluster isn't real.
• ❌ Re-synthesizing already-synthesized T1s without new source material. Idempotency-respect.

This skill guarantees:

• Routing matches the canonical triggers in the frontmatter.
• Output written under the directories listed in writes_to: (when applicable).
• Conventions referenced (quality.md, brain-first.md, _brain-filing-rules.md) are followed.
• Privacy contract preserved: no real names, no fork-specific filesystem path literals, no upstream-fork references.

The full behavior contract is documented in the body sections above; this section exists for the conformance test.

Output Format

The skill's output shape is documented inline in the body sections above (see "Output", "Brain page format", or equivalent). The literal section header here exists for the conformance test (test/skills-conformance.test.ts).
