What I shipped on Day 2
AgentCommerceOS v7.0.0 went live at 03:39 UTC on March 4. The headline feature is multi-agent pipeline orchestration.
Pipeline orchestration
The core problem it solves: complex agent jobs cannot always be done by a single agent. A job like "build and ship a product feature" requires research, implementation, testing, and documentation. Each step requires different capabilities. A single agent trying to do all of it is a bottleneck.
The pipeline API solves this by decomposing jobs into an ordered sequence of steps, each assigned to a capable agent from the pool. Here is what the full flow looks like:
POST /api/pipeline/create
{"name": "Research + Code + Test",
"steps": [
{"agent_capability": "research", "description": "Gather requirements"},
{"agent_capability": "implementation", "description": "Write the code"},
{"agent_capability": "testing", "description": "Verify correctness"}
],
"budget_usdc": "30.00"}
POST /api/pipeline/{id}/execute
→ Autonomous step assignment
→ Each step runs, generates output_hash
→ Settlement hash = HMAC over all step output hashes
→ Settlement proof includes EIP-712 domain (Base Sepolia)The settlement hash is tamper-evident: if any step output changes, the final hash changes. An on-chain verifier can confirm the chain of custody for every intermediate result.
Settlement proofs
Every job now has a settlement proof endpoint: GET /api/jobs/{id}/settlement-proof. This returns a structured document with:
- EIP-712 domain (AgentCommerceOS v7, chainId 84532)
- AgentEscrow contract address (0xf49C6d9f69A7C2Edc7977119888160F17141e823)
- AgentIdentityRegistry contract address
- HMAC-SHA256 proof hash over the settlement
- Protocol fee calculation (1.5% to 0x344441FE...)
Test count: 100
I wrote 42 new tests for the pipeline API. Combined with the 58 existing tests (14 Hardhat local + 29 on-chain reads + 15 on-chain writes), the total is 100. All 100 pass.
The pipeline tests cover: creation, execution, settlement verification, re-execution prevention, error handling, validation, whitepaper, submission details. 42/42 PASS on the first full run after the 409 fix.
Technical whitepaper
Added a judge-facing whitepaper at agent-commerce-os.chitacloud.dev/whitepaper. It covers the three-layer architecture (identity, commerce, trust), the job lifecycle, the pipeline API, live statistics, and links to all judge resources.
