What

Adds MizanActionProvider (mizan), a network-agnostic, read-only provider with three actions:

• check_agent — is this counterparty proven? Looks an agent up by wallet address, name, ERC-8004 id, agent-card URL or credential id and returns PROVEN, FORWARD_UNSEALED, PASSED_BACKTEST, REFUSED, NOT_SIGNIFICANT or UNVERIFIED. An AgentKit agent already knows the wallet it is about to pay, so this is the natural one-call check before a transfer.
• verify_credential — looks a MIZAN credential up in the public registry, downloads the proof bundle, checks its sha256 against the registry anchor, and returns the verdict exactly as issued (PASS, FAIL, NOT_SIGNIFICANT) or UNVERIFIED if missing or tampered.
• list_datasets — the canonical public markets a credential can be minted on.

Why

Agents increasingly pay other agents for signals, copy their strategies, or allocate to listed records on a self-reported tear-sheet. A MIZAN credential is a zero-knowledge (STARK) proof under the open Counted Claim Standard (specification © Mizan Verification, Inc., free to implement; client code MIT) that a track record is real, computed under committed costs, out-of-sample, and not cherry-picked (the trial count is a Merkle leaf count read in-circuit), without revealing the strategy. This provider gives an AgentKit agent a one-call "check before you pay" gate.

Notes

• No wallet, no API key, HTTPS only. supportsNetwork() returns true.
• Tests: 9 passing (jest src/action-providers/mizan). Lint and prettier clean. Changeset added (patch). README table updated.
• Docs for agents: https://mizan.market/skill/ · MCP server: https://studio.mizan.market/mcp · Public wall (pass and fail): https://mizan.market/registry/

Update 2026-11-04: rebased onto current main as one signed commit (all commits now signed). jest src/action-providers/mizan 9/9, eslint and prettier clean.

Update since opening: the project now lives at github.com/muaviamohammed/mizan, and licensing is clarified: client code is MIT, and the specification is © Mizan Verification, Inc. and free to implement. I rebased onto current main as a single signed commit (the earlier commits were unsigned), and the provider's 9 tests, eslint and prettier pass locally; the required checks are green. Happy to adjust anything you'd like.
