CCL Manager

The Claude Context Library (CCL) is a dedicated Obsidian vault containing technical reference documents that give Claude persistent knowledge across sessions. It is separate from Matt's Vault and optimized for machine-readable content.

Adding a New Context Document

Small single-file contexts (direct filesystem write recommended)

Direct filesystem write is faster and doesn't require Obsidian to be open:

1. Compose the content (use obsidian-markdown skill for frontmatter)
2. Write directly to the CCL path using the Write tool:

   ~/Library/Mobile Documents/iCloud~md~obsidian/Documents/Claude Context Library/contexts/<domain>/<name>.md
   

3. Register in known-docs.md if it's a named documentation set

Large multi-file documentation harvests

Use the doc-harvest plugin for bulk content (entire libraries, API docs, large sites).

After a doc-harvest:

• Source files land in the configured output path
• Register the set in known-docs.md with name, source URL, page count, and date harvested

---

known-docs.md

This file is the registry of all documentation sets in the CCL. Update it whenever a new set is harvested.

Format:

## <name>

- **Source:** <URL or description>
- **Pages:** <count>
- **Harvested:** <YYYY-MM-DD>
- **Path:** `contexts/<domain>/<folder-or-file>`
- **Notes:** <any gotchas or access patterns>

Read it:

obsidian read "known-docs.md" vault="Claude Context Library"

---

Updating an Existing Context

For small additions, use append:

obsidian append "contexts/technical/pihole-config.md" vault="Claude Context Library" content="## Update YYYY-MM-DD\n\n<new content>"

For full rewrites, use direct filesystem write (faster than CLI for large content replacements).

---

Auditing the CCL

List all files

obsidian files vault="Claude Context Library" format=json

Search for a topic

obsidian search "tailscale" vault="Claude Context Library" format=json

Open CCL in Obsidian (if not already open)

open "obsidian://open?vault=Claude%20Context%20Library"
sleep 3

---

Silent Fallback Warning

vault= silently falls back to the active vault if "Claude Context Library" is not open in Obsidian. Always verify the vault is open before using the CLI, or use direct filesystem writes to avoid this issue entirely.
