Claw Agent Protocol (CAP) Skill

This skill enables any AI agent to interact with a user's personal data through the Claw Agent Protocol (CAP), a lightweight MCP server that provides a canonical, real-time view of personal data from various sources.

Core Concepts

CAP solves the data chaos problem: Instead of dealing with dozens of different APIs and data formats, CAP provides a single, consistent interface to all of a user's personal data.

• Real-Time Translation Layer: CAP fetches data on-demand from connected accounts (Gmail, Google Calendar, Notion, Slack, etc.) without storing it locally. Data stays at the source, queries are on-demand, security is delegated to OAuth providers.
• MCP-Native: CAP is a Model Context Protocol (MCP) server, making it compatible with any MCP-enabled client (OpenClaw, Claude Desktop, etc.).
• Canonical Schema: CAP exposes data through a consistent, canonical schema regardless of the original source. This eliminates integration complexity and improves agent reliability.

Key Constructs

CAP organizes data into two primary constructs:

1. Resources (Shelves): Raw, normalized data accessible via canonical URIs. These represent the fundamental categories of a user's digital life.
2. Tools (Views): High-level, task-oriented functions that combine data from multiple shelves to provide refined, actionable perspectives.

Usage Patterns

Querying Shelves

Query shelves using read operations on resource URIs with optional filters:

read cap://calendar?start_date=today
read cap://tasks?status=pending&priority=high
read cap://[email protected]&unread=true

Executing Views

Call tools to execute pre-compiled views:

tools.today_briefing()
tools.client_pipeline(client_name="Acme Corp")
tools.knowledge_search(query="project requirements")

Utility Scripts

Use these scripts for common CAP operations:

• generate_briefing.py: Format CAP data into readable daily briefings

  python /home/ubuntu/skills/claw-agent-protocol/scripts/generate_briefing.py '<json_data>'

• validate_cap_data.py: Validate CAP data against schema requirements

  python /home/ubuntu/skills/claw-agent-protocol/scripts/validate_cap_data.py '<json_data>'

• export_cap_data.py: Export CAP data to various formats (CSV, JSON, Markdown)

  python /home/ubuntu/skills/claw-agent-protocol/scripts/export_cap_data.py --format csv --shelf calendar --output events.csv

• build_query.py: Generate CAP query strings from natural language

  python /home/ubuntu/skills/claw-agent-protocol/scripts/build_query.py "show me high priority tasks due this week"

Best Practices

1. Always check provenance: Use the source field to understand where data originated and link back to the original source.
2. Respect sensitivity tiers: Handle S1 (public), S2 (internal), and S3 (sensitive) data appropriately.
3. Use confidence scores: When confidence is below 0.8, verify data with the user before taking action.
4. Prefer views over raw queries: Use pre-compiled views (tools) when available—they're optimized and tested.
5. Cache judiciously: CAP data is real-time, but you can cache results briefly for performance. Never cache beyond the current session.
