Compare the resulting `elf_sha256` and `image_id` to the manifest +## Publishing an Agent + +The bundle workflow streamlines distribution by creating a self-contained directory that integrators can verify without any build tools. Use `agent-pack pack` to produce a distributable bundle from your built agent. + +### Creating a Bundle + +After building your agent and populating your manifest, create a bundle: + +```bash +agent-pack pack \ + --manifest dist/agent-pack.json \ + --elf target/riscv-guest/riscv32im-risc0-zkvm-elf/release/zkvm-guest \ + --out my-agent-bundle \ + --cargo-lock Cargo.lock +``` + +This produces a directory containing: + +``` +my-agent-bundle/ +├── agent-pack.json # Manifest with computed hashes +└── artifacts/ + └── zkvm-guest # Copy of the ELF binary +``` + +The manifest's `artifacts.elf_path` is automatically set to a relative path (`artifacts/zkvm-guest`), making the bundle portable. + +### What Gets Computed + +The `pack` command recomputes certain fields to ensure the manifest matches the actual binary: + +- **elf_sha256**: SHA-256 of the ELF binary +- **cargo_lock_sha256**: SHA-256 of Cargo.lock (if provided) +- **image_id**: RISC Zero IMAGE_ID (requires `--features risc0`) + +Fields that are not recomputed include `agent_code_hash` (derived from source at build time) and metadata fields like `inputs` and `actions_profile`. These must be populated in your input manifest before packing. + +### Verifying a Bundle + +Recipients verify the bundle using the same tool: + +```bash +agent-pack verify \ + --manifest my-agent-bundle/agent-pack.json \ + --base-dir my-agent-bundle +``` + +This checks that the ELF binary matches the declared hash. If built with `--features risc0`, it also verifies the IMAGE_ID matches. + +### Distribution + +Ship the entire bundle directory. Integrators receive: + +1. The manifest with all cryptographic commitments +2. The exact ELF binary you built +3. Everything needed to verify authenticity offline + +They can then compare the `image_id` against on-chain registrations to confirm the agent is legitimate. + +### What Changes Each Hash + +Understanding what triggers hash changes helps with versioning: + +| Change | agent_code_hash | elf_sha256 | image_id | +|--------|-----------------|------------|----------| +| Agent source code | Yes | Yes | Yes | +| SDK version | No | Yes | Yes | +| Rust toolchain | No | Yes | Yes | +| Cargo.lock dependencies | No | Yes | Yes | +| RISC Zero version | No | Yes | Yes | +| Manifest metadata only | No | No | No | + +The `agent_code_hash` is the most stable identifier - it only changes when your agent's source files change. The `image_id` is the most comprehensive - any change to the build environment affects it. + +## Marketplace Ingestion and On-Chain Verification + +Offline verification with `agent-pack verify` confirms that a manifest is well-formed and that the ELF binary matches its declared hashes. However, this does not guarantee the agent is actually registered on-chain. A marketplace accepting agent submissions must take the additional step of querying the KernelExecutionVerifier contract. + +The `verify-onchain` command bridges this gap. It reads the `agent_id` and `image_id` from the manifest, queries the contract registry, and confirms the values match. + +### Usage + +```bash +agent-pack verify-onchain \ + --manifest agent-pack.json \ + --rpc https://sepolia.infura.io/v3/YOUR_KEY \ + --verifier 0x9Ef5bAB590AFdE8036D57b89ccD2947D4E3b1EFA +``` + +Note: The `verify-onchain` command requires building with the `onchain` feature: + +```bash +cargo build -p agent-pack --features onchain +``` + +### Exit Codes + +The command returns structured exit codes for CI integration: + +| Exit Code | Meaning | +|-----------|---------| +| 0 | Agent is registered and image_id matches | +| 1 | Error (RPC failure, invalid manifest, etc.) | +| 2 | Agent is registered but image_id differs | +| 3 | Agent is not registered (agent_id returns zero) | + +### Marketplace Workflow + +A complete verification workflow for marketplaces: + +1.
