atproto-pro

An agent skill for the AT Protocol — deep protocol expertise for building on the open social web.

Covers identity (DIDs, handles), repositories, Lexicons, XRPC, OAuth (PKCE + DPoP + PAR), firehose/sync, data model, and all official specs. Provides production-grade guidance for TypeScript (@atproto/api, @atproto/oauth) and Go (indigo) SDKs.

What's Included

A single skill: atproto-pro

When activated, the agent gains deep knowledge of:

• Identity: DID resolution (did:plc, did:web), handle verification, bidirectional identity checks
• OAuth: Full atproto OAuth 2.1 profile with PKCE, DPoP, and PAR — confidential and public client flows
• Data Model: Records, collections, CIDs, blobs, DAG-CBOR encoding, $type dispatch
• Lexicons: Schema authoring, evolution rules, NSID conventions, validation semantics
• XRPC: HTTP API patterns, service proxying, inter-service auth, error handling
• Firehose: subscribeRepos event stream, cursor-based resumption, record-level sync
• Repositories: MST structure, CAR import/export, commit signing, at:// URI addressing

What This Skill Does Not Cover

General-purpose coding, UI development, databases, or infrastructure outside the AT Protocol. When a task is purely about atproto, this agent should be the one responding.
