# Wiki Capture — Conversation to Wiki Note

You are preserving knowledge from the current conversation as a permanent wiki note. The goal is to extract the *substance* — the knowledge itself — not a summary of what was said.

## Before You Start

1. **Resolve config** — follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (walk up CWD for `.env` → `~/.obsidian-wiki/config` → prompt setup). This gives `OBSIDIAN_VAULT_PATH` and `OBSIDIAN_LINK_FORMAT` (default: `wikilink`).
2. Read `$OBSIDIAN_VAULT_PATH/index.md` to understand existing wiki content (avoid duplicates)
3. Read `$OBSIDIAN_VAULT_PATH/hot.md` if it exists — it gives context on recent activity

When writing internal links in Step 5, apply the link format from `llm-wiki/SKILL.md` (Link Format section) using the `OBSIDIAN_LINK_FORMAT` value.

## Step 1: Identify What's Worth Preserving

Scan the conversation. Ask: what knowledge emerged here that would be valuable in 3 months with no memory of this chat?

Worth preserving:
- Decisions made and *why* they were made
- Analysis, frameworks, mental models developed
- Technical findings, patterns, or procedures
- Synthesized understanding of a topic
- Clear explanations of a concept that took effort to arrive at
- Key facts from an external source discussed in the conversation

Skip:
- Logistics, scheduling, pleasantries
- Exploratory back-and-forth where no conclusion was reached
- Content that's already in the wiki

If nothing material emerged, tell the user and stop.

## Step 2: Classify the Content Type

Assign one of five types — this determines the target folder and tone:

| Type | Description | Target folder |
|---|---|---|
| `synthesis` | Multi-step analysis or an answer to a specific question that required reasoning | `synthesis/` |
| `concept` | A definition, framework, or mental model (what a thing *is*) | `concepts/` |
| `source` | Summary of an external document, article, or resource discussed | `references/` |
| `decision` | A strategic, architectural, or design choice and its rationale | `synthesis/` |
| `session` | A complete discussion summary when the conversation spans multiple topics | `journal/` |

If the content clearly belongs to a specific project (detected from context or user mention), place it under `projects/<project-name>/<category>/` instead.

## Step 3: Rewrite as Declarative Knowledge

Do **not** write a summary of the conversation. Write the knowledge itself, in declarative present tense:

- Not: "The user asked about X and Claude explained that..."
- Yes: "X works by..."
- Not: "We decided to use Y because..."
- Yes: "Y is preferred over Z because [reason]. [^[inferred] if the rationale was implied, not stated explicitly]"

Apply provenance markers per `llm-wiki`:
- *Extracted* — explicitly stated in the conversation (no marker)
- *Inferred* — generalized or synthesized from the conversation → `^[inferred]`
- *Ambiguous* — disputed, uncertain, or contradictory → `^[ambiguous]`

## Step 4: Generate a Slug and Title

Derive a clear, descriptive title from the content. Slugify it:
- Lowercase, words separated by hyphens
- Max 50 characters
- Avoid dates in the slug (the frontmatter has `created`)

## Step 5: Write the Wiki Note

Create the file at the target path with required frontmatter:

```yaml
---
title: >-
  <Title>
category: <synthesis|concepts|references|journal|skills>
tags: [<2-5 domain tags from taxonomy>]
sources:
  - conversation:<ISO-date>
created: <ISO-8601 timestamp>
updated: <ISO-8601 timestamp>
summary: >-
  <1-2 sentences, ≤200 chars, answering "what knowledge does this page hold?">
provenance:
  extracted: 0.X
  inferred: 0.X
  ambiguous: 0.X
base_confidence: 0.42
lifecycle: draft
lifecycle_changed: <ISO date today>
---
```

Body structure by type:

**synthesis / decision:**
```markdown
# Title

## Context
<What prompted this — the problem or question being addressed>

## Finding / Decision
<The core knowledge or conclusion>

## Reasoning
<Why this is the case or why this choice was made>

## Implications
<What follows from this — what to watch for, next steps, trade-offs>

## Related
<[[wikilinks]] to connected pages>
```

**concept:**
```markdown
# Title

<Definition in one clear sentence.>

## What It Is
<Explanation of the concept>

## How It Works
<Mechanism or structure>

## When to Use
<Applicability, conditions, trade-offs>

## Related
<[[wikilinks]]>
```

**source:**
```markdown
# Title

> Source: <title or URL>

## What It Covers
<What the source is about>

## Key Points
<Bulleted claims with provenance markers>

## Open Questions
<What it raises but doesn't answer — omit if none>

## Related
<[[wikilinks]]>
```

**session:**
```markdown
# Title

*Session captured: <date>*

## Topics Covered
<Brief list>

## Key Takeaways
<The 3-5 most important things that emerged>

## Decisions Made
<Any explicit decisions, with rationale>

## Open Questions
<What remains unresolved>

## Related
<[[wikilinks]]>
```

Every note must link to at least 2 existing wiki pages. Search `index.md` before writing. If fewer than 2 related pages exist, create minimal stubs for the most important concepts referenced.

## Step 6: Update Tracking Files

**`index.md`** — Add the new page under its category section.

**`log.md`** — Append:
```
- [TIMESTAMP] CAPTURE type=<type> page="<path>" title="<title>"
```

**`hot.md`** — Update **Recent Activity** with what was just captured. Update **Key Takeaways** if the note introduced something worth flagging. Update `updated` timestamp.

## Step 7: Confirm to User

Report the saved path and title:
```
Saved to: projects/<name>/synthesis/<slug>.md
Title: <Title>
Type: synthesis
```

## Quality Checklist

- [ ] Content rewritten as declarative knowledge (not a chat transcript)
- [ ] Type classified correctly; target path is in the right folder
- [ ] Frontmatter complete with title, category, tags, sources, summary, provenance
- [ ] At least 2 wikilinks to existing pages
- [ ] `index.md`, `log.md`, and `hot.md` updated
- [ ] Confirmed save path to user

## QMD Refresh After Vault Writes

QMD is a search index, not the source of truth. If `$QMD_WIKI_COLLECTION` is empty or unset, skip this step. Run it only after this skill has written or rewritten vault markdown. If QMD refresh fails, do not roll back the vault changes; report the QMD status separately.

Use `$QMD_CLI` if set; otherwise use `qmd`.

```bash
${QMD_CLI:-qmd} update
```

If the output says vectors are needed or embeddings may be stale, run:

```bash
${QMD_CLI:-qmd} embed
```

Verify the collection with either:

```bash
${QMD_CLI:-qmd} ls "$QMD_WIKI_COLLECTION"
```

or, when a specific page path is known:

```bash
${QMD_CLI:-qmd} get "qmd://$QMD_WIKI_COLLECTION/<page>.md" -l 5
```

Record one of:
- `QMD refreshed: update + embed + verified`
- `QMD refreshed: update only + verified`
- `QMD skipped: QMD_WIKI_COLLECTION unset`
- `QMD skipped: qmd CLI unavailable`
- `QMD failed: <short error summary>`
