description: Unified knowledge capture and retrieval for URLs, video/article/paper extracts, social posts, and agent research outputs. Use when saving anything worth re-finding later, summarizing external content, tracking sourced claims, or answering "where did we store that?" questions.

# Knowledge Skill

File-based knowledge organization. Capture fast, search later, clean up automatically.

## Installation

```bash
clawhub install knowledge
```

This installs `scripts/know` — add to PATH or use full path:
```bash
~/.openclaw/skills/knowledge/scripts/know
```

## Storage Location

Default: `~/.soulshare/agent/knowledge/`

Configurable via `~/.config/know/config` or env `KNOWLEDGE_DIR`.

```
knowledge/
├── INDEX.md      # Auto-maintained browsable index
├── urls/         # Bookmarked URLs
├── extracts/     # Video/article/paper summaries
├── posts/        # Social content (tweets, threads)
└── research/     # Agent-generated research
```

## Adding Content

```bash
know add url <url> --title "..." --tags "a,b" [--summary "..."]
know add video <url> --title "..." --tags "a,b" [--summary "..."]
know add extract --source <url> --type video|article|paper --title "..." --tags "a,b"
know add post --source <url> --title "..." --tags "a,b"
know add research --title "..." --tags "a,b" [--summary "..."]
```

Each add writes a markdown file with YAML frontmatter and updates `INDEX.md`.

## Searching

```bash
know search "query"           # Grep across all entries
know recent --limit 10        # Recent entries
know list --tags security     # Filter by tag
```

## Cleanup & Maintenance

```bash
know tidy                     # Audit: find issues
know tidy --fix               # Auto-fix: normalize tags, move misplaced files, remove empty
know validate                 # Check frontmatter schema
know reindex                  # Rebuild INDEX.md
know config                   # Show active config paths
```

**Recommended:** Run `know tidy --fix` in heartbeats or nightly cron.

## Data Model (frontmatter)

```yaml
---
type: url|extract|post|research
title: "Entry title"
source_url: "https://..."
source_kind: url|video|article|paper|post|research
tags: ["tag1", "tag2"]
added: "2026-02-26"
added_by: "agent-name"
summary: "One-line summary"
---
```

## QMD Integration

Plain markdown → QMD-indexable.

```bash
qmd collection add ~/.soulshare/agent/knowledge --name knowledge
qmd search "query" --collection knowledge
```

## Discipline

- If it's useful later → `know add` immediately
- Don't leave knowledge only in `memory/YYYY-MM-DD.md`
- Every entry needs tags + summary
- Let `know tidy --fix` handle normalization
