Bernstein
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Orchestrate 40+ CLI coding agents (Claude Code, Codex, Gemini CLI, Aider, and more) against one goal in parallel. Decomposes into tasks, assigns roles, isolates each task in its own git worktree, and gates every merge on lint, types, and tests. Scheduling is plain Python with no LLM in the coordination loop, so a run is reproducible end to end. A lineage spine and replay journal are always on; an opt-in HMAC-chained audit log and signed receipts let a reviewer who did not execute the run check it offline, without rerunning it. Signature and hash-chain checks read the on-disk records alone; the HMAC leg needs the key the chain was written with.

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
