Second Brain Aphorism

Use this skill to turn the user's second-brain material into a concise, personally grounded thought. The result should feel like a distilled insight from the user's own thinking, not a generic inspirational quote.

Default to Chinese unless the user asks for another language.

Workflow

1. Clarify the requested shape only when necessary.
   - If the user says "感悟", produce one short paragraph.
   - If the user says "箴言", "金句", or "短句", produce concise aphoristic lines.
   - If unspecified, produce one 感悟 and one compressed 箴言.
2. Run lightweight second-brain recall.
   - Prefer the user's local second brain over web knowledge.
   - Resolve local paths without hardcoded personal information:
   • Prefer SECOND_BRAIN_WIKI_ROOT when set.
   • Otherwise try $SECOND_BRAIN_ROOT/llm-wiki when SECOND_BRAIN_ROOT is set.
   • Otherwise try common user-local candidates such as ~/Hbrain/llm-wiki.
   • If no likely wiki root exists, infer it from the current project or ask one concise question.
   • Once the wiki root is found, use:
   • Core questions: <wiki-root>/my-core-questions.md
   • Anchor index: <wiki-root>/links/index.md
   • Read my-core-questions.md and links/index.md if they exist.
   • Select 1-3 relevant anchor pages from links/*.md and read only those pages.
   • Run focused recall when available:

gbrain search "<user's exact topic>" --limit 5
gbrain search "<selected anchor or close synonym>" --limit 5
cm context "<user's exact topic>" --json --limit 5 --history 5

3. Extract a "seed of tension" before writing.
   - Name the lived tension: what is being pulled against what?
   - Name the user's recurring anchor or long-term question.
   - Name the practical turn: what changes in how one sees, chooses, or acts?
4. Generate the line or paragraph.
   - Write from the recalled context, not from generic advice.
   - Prefer concrete verbs, precise nouns, and a small paradox.
   - Remove motivational filler, slogans, and abstract padding.
   - If the recall is thin, be transparent and write a lower-confidence draft.
5. Present the result.
   - For normal requests, output:
   • 感悟： one paragraph, 80-180 Chinese characters
   • 箴言： one line, 8-32 Chinese characters
   • For batch requests, give 3-7 numbered candidates.
   • Include a concise 第二大脑回路 receipt unless the user explicitly asks for copy-only output.

Style Guide

Read references/style-guide.md when the user asks for a specific tone, more variants, quote-card copy, article endings, or when the first draft risks sounding generic.

Grounding Rules

• Do not claim the user believes something unless it is supported by recall.
• Do not invent book titles, source notes, anchors, or personal experiences.
• Do not search the web unless the user explicitly asks for outside references.
• Do not write back to the second brain unless the user explicitly asks to save, archive, 沉淀, 写入, or update.
• If recall tools fail, continue with available anchor files and briefly state what failed.

Writeback

Default to no writeback. When the user explicitly asks to save the result:

1. Choose the smallest durable target:
   - queries/ for reusable generated answers or quote collections.
   - concepts/ for a stable idea that should become a concept page.
   - links/ only when updating an existing cognitive anchor.
   - practices/ only when the output implies a repeatable routine.
2. Preserve existing frontmatter and content.
3. Add the generated line plus the recall receipt or source context.
4. Bump updated dates on edited wiki pages.

Quality Checklist

• It can be traced to at least one recalled anchor, note, or core question.
• It says one thing sharply instead of three things vaguely.
• It contains a tension, reversal, or implication.
• It sounds like a private notebook becoming public for a moment.
• It remains useful even if stripped of decorative language.
