What's Inside
Slash Commands2
Audit Chain
/audit-chain
Walk the receipt chain in ./receipts/ verifying every signature and hash link. Detects insertions, deletions, and tampering across the entire audit trail.
Verify Receipt
/verify-receipt
Verify a single Ed25519-signed receipt file. Returns exit 0 if valid, 1 if tampered, 2 if malformed.
Agents2
policy-enforcer
/policy-enforcer
Cedar policy author and reviewer for Claude Code tool calls. Writes, audits, and explains Cedar policies that govern Bash, Edit, Write, WebFetch, and other tools. Use when you need declarative, formally verifiable rules for what an AI agent can and cannot do in a project.
receipt-verifier
/receipt-verifier
Expert in Ed25519 signed receipts, JCS canonicalization, hash chains, and offline verification. Use when you need to verify receipt authenticity, audit a receipt chain, detect tampering, or explain why verification failed.
