Documentation
Everything you need to evaluate, implement, and operate Claw EA.
Get started in 5 minutes
Install the SDK, generate a DID keypair, emit a proof bundle, and verify it.
1. Install the SDK
npm install @clawbureau/clawsig-sdk
2. Generate a DID keypair
npx clawsig keygen --out ./agent-key.json
# Output: did:key:z6Mkf...xy3m (your agent DID)
3. Sign a commit
COMMIT_SHA=$(git rev-parse HEAD)
npx clawsig sign "commit:$COMMIT_SHA" --key ./agent-key.json
# Output: commit.sig.json
4. Verify the signature
npx clawsig verify ./commit.sig.json
# Output: PASS — signature valid for did:key:z6Mkf...xy3m
5. Add to your CI pipeline
See the GitHub Actions proof pipeline guide for a complete workflow file.

SDK Reference
The @clawbureau/clawsig-sdk package provides TypeScript types and utilities for the Clawsig Protocol.
Core types
| Type | Description | Schema |
|---|---|---|
WorkPolicyContract | Signed, content-addressed policy document | work_policy_contract.v1.json |
ScopedTokenClaims | CST claim set with scopes and policy pin | scoped_token_claims.v1.json |
GatewayReceipt | Signed model gateway attestation | gateway_receipt.v1.json |
ToolReceipt | Signed tool invocation attestation | tool_receipt.v1.json |
ProofBundle | Hash-linked event chain with receipts | proof_bundle.v1.json |
ReceiptBinding | Ties a receipt to a run_id + event_hash | receipt_binding.v1.json |
CommitSignature | Ed25519 signature over a git commit SHA | message_signature.m1.json |
Key functions
| Function | Description |
|---|---|
keygen() | Generate an Ed25519 keypair and DID |
sign(message, privateKey) | Sign a message (commit SHA, bundle hash) with Ed25519 |
verify(signature, publicKey) | Verify an Ed25519 signature — returns PASS/FAIL with reason code |
hashBundle(bundle) | Compute canonical SHA-256 hash of a proof bundle |
verifyBundle(bundle, config) | Full bundle verification: signatures, bindings, event chain integrity |
resolveDidKey(did) | Resolve a did:key to an Ed25519 public key |

Clawsig Protocol v0.1
Five composable primitives. Everything else is built on these.
1. Work Policy Contract (WPC)
Signed, immutable, content-addressed policy document. Defines what an agent may do before it runs.
2. Capability Scoped Token (CST)
Short-lived, scope-hashed, job-bound permission token. Optionally pinned to a policy hash.
3. Receipt
Signed attestation at an enforcement boundary (gateway, tool, approval). Not a log entry.
4. Proof Bundle
Hash-linked event chain + receipts + Ed25519 signature. Offline-verifiable, portable.
5. Verifier
Deterministic PASS/FAIL engine. Unknown schema/version/algorithm fails closed. Machine-readable reason codes.
