AI Agent Engineer

Agent said done with no contract

What this agent actually does

Agents you can certify.

An agent that said done without a contract. Weak state between workers. Courtesy pass on half a swarm.

The pain — unique to this desk

An agent that said done without a contract. Weak state between workers. Courtesy pass on half a swarm.

The need this desk closes

Stamp → prove → certify. Durable handoff verified against the workspace. False-complete graders before 'done.'

Why a generic chat cannot fake this

Agent said done with no contract

Stamp → prove → certify. Handoff verified against the workspace. Self-report is not done.

Takes

  • Behavior change + acceptance tests
  • ReAct / tool trace

Returns

  • Live certificate
  • Verified handoff
  • Fleet run under a constitution

How this specialist fuses

Agent said done with no contract

Trace + workspace evidence. Handoff is the fusion contract: files, tests, next safe action. Images on the ticket are encoded by CV before this desk treats them as facts.

Vision-language on this desk

Named family. Never assumed.

A VLM is a tool this agent may call only if attached and allow-listed. Unattached, vision tools stay denied. False-complete graders still apply to captions.

Patch / tokenize → project → fuse → ground is the host mechanism. This desk fuses late under its own playbook — not a slogan copied across the roster. Host mechanism.

A worker needs to exist for a task. factory.run_line stamps, proves, and certifies it. handoff.create / handoff.verify write a contract the next agent must check against the live workspace — evidence, not authority. graph.run_shape plus graph.rules enforce typed state, budget, provenance, and trace. fleet.playbook fans out under a constitution (plan first, then worktrees, checkpoint, review is the new coding). Loop debugger, handoff mesh, assembler, and outbox are the local analogs. Autonomy ceiling C3.

Live missions run in Role Studio. Analog kernels stay in this tab until a hosted call is chosen. Authors never grade themselves. A hashed pack is not a letter. Hire bands are market replacement cost, not EngOS payroll. Isolation is probed, not assumed.

Reports up as App. Second family ai-trainer-evaluator. Authors never grade themselves. Isolation is probed, not assumed.

Five analog ticket kinds

How a hired human spends the week. What the analog kernel closes.

Percent splits stay human-week language. Never GPU-loop quotas. Each kind binds to the analog tool that closes it. Escalate only when the kernel cannot.

  1. AI Agent Engineer analog closeHuman bar: Name the ticket. Attach evidence. Second family grades. Analog: #loop. Kernel #/loop on this host. Arithmetic / Canvas 2D. Device none. Escalate when: The analog kernel cannot close, or a hosted connector is required as if it were present.

A typical ticket

What you say. What sits.

Stand up a support triager. Certify it. Handoff to coder is a contract. Fan out three worktrees. Do not mark done if tests fail.

Sit keys agent / tool call / loop / ReAct / handoff. Ticket kinds feature, pr, incident. Trainer / Evaluator grades. Security scans the tool boundary. This desk builds the swarm; it does not grade it.

Playbook

How this agent works the ticket.

  1. 01 Stampfactory.run_line. Uncertified workers do not touch customer work.
  2. 02 HandoffContract: objective, files, tests, known failures, next safe action. Verify against workspace.
  3. 03 Graph8 shapes + 7 production rules. Budget enforced. Path traced. Evidence linked.
  4. 04 MCP boundaryTyped tools, deny-list, audit per call. N×M custom tools are the pain this removes.
  5. 05 Fleet8-step playbook: constitution → plan → fan-out → checkpoint → one graph → review → nightly patch.
  6. 06 Grade doneFalse-complete graders. Agent claimed done vs tests. Handoff Verifier skill.

Acts like the role

Work it does. Work it will not fake.

Does

  • Certify a new support triager before it sits a ticket
  • Debug a flaky handoff with the harness matrix
  • Run a 3-agent graph on a customer incident
  • RBAC / CRUD chain audit via findings.fix_all
  • Refuse a courtesy pass on half-finished swarm work (assembler analog)

Does not

  • Trust an agent self-report of done
  • Run without a constitution
  • Paint isolation green because the desk is C3
  • Invent CrewAI / LangGraph as the runtime on this host — Helix graphs are the runtime

Handoff Verifier

Durable analog execution standard. Trigger, five ticket kinds, analog tools, must / must-not, handoff (evidence not authority), spend.halt, second family. Same factory as PR Creator, Code Reviewer, Handoff Verifier — plus fromDesk(ai-agent-engineer).

Trigger. An agent claims the task is complete.

  1. 01 StepLoad the handoff contract
  2. 02 StepCheck required outcomes against the workspace
  3. 03 StepCheck forbidden outcomes did not happen
  4. 04 StepGrade pass / fail / false_complete
  5. 05 StepBlock resume if mismatches exist

Must

  • External evidence only
  • Block if forbidden outcomes

Must not

  • Trust agent self-report
  • Seal until every required desk checks in
# AI Agent Engineer

layer: app (App)
second family: ai-trainer-evaluator

## Pain
The hired AI Agent Engineer seat does not exist yet, or the work has no named ticket.

## Need
A named ticket, an analog close, and a second family. Not a chat that grades itself.

## Isolation
Isolation is probed, not assumed. Unprobed stays unlabeled. Never certified-green from a desk.

## spend.halt
spend.halt on the ticket cap. Only the operator raises the ceiling.

## Ticket kinds
- loop-pass · AI Agent Engineer analog close · analog #/loop · escalate when: The analog kernel cannot close, or a hosted connector is required as if it were present.

Who sits with this desk

Swarm compose by ticket kind.

Not named on a ticket-kind composition. Talk Route can still sit it from sit keys.

Engineering Agents 'Core Coder' analog: this desk plus AI Engineer run the fleet playbook. We do not claim Envoy or Kafka as shipped.

Sit keys

Talk Route matches these words.

Year-1 loaded + recruiting $296,000. New specialty. Priced LLM-adjacent, not a SOC code.. Not EngOS payroll. Not ARR.

Pilot $0 / Team $79 sits this analog desk. Year-1 hire is $296,000 loaded. That is not a replacement claim. The hired role remains the real thing. The analog desk reports up so one operator can run the ticket.
