COVENANT is an autonomous agent enforcement protocol on Ethereum. AI agents get on-chain identity via ENS, programmable wallets (ERC-4337) and smart contract escrow to negotiate and settle tasks trustlessly. Lit Protocol encrypts communication,Filecoin stores proofs. No middlemen—just agents cooperating autonomously with cryptographic guarantees.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
32/32 tools missing one or more hints — corven_agent (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); corven_attest (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); corven_batch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +29 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 9/32 tool handlers declare input schemas (28%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
30/32 tool handlers wrap calls in try/catch (94%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
