AI agents for field service with a fail-closed write-gate

说明与用途

Foreman+ 利用 AI 代理舰队从照片和语音笔记中提取设备数据，通过 fail‑closed 写入门验证事实，并仅存储已验证的信息，为后续技术人员提供透明度和信任。

问题

Field service technicians often lose or misremember key facts such as equipment model, serial number, and quoted price, leading to inconsistent records and re‑diagnosis by subsequent technicians.

结果

Foreman+ demonstrates that an AI agent fleet can reliably capture and store field‑service facts with a fail‑closed write‑gate, ensuring that only verified data is persisted while rejected proposals remain visible as claims.

工作流

• 1. Technician takes a photo of the equipment nameplate and speaks a brief description of the problem.
• 2. The intake agent extracts model and serial number from the image; if unreadable, the field remains UNKNOWN. 3. The intake agent records the spoken notes as plain files. 4. The estimator agent searches the fleet memory for similar past jobs and proposes an estimate. 5. The closer agent builds a close‑out document without LLM calls and briefs the next technician. 6. Every proposed fact passes through the write‑gate, which performs identity, size, and Gemini verifier checks. 7. Approved facts are written to Cloud SQL; rejected proposals are logged with the verifier’s reason. 8. The ledger displays all writes, including refusals, with source chips and agent provenance.

证据

Foreman+ is an AI agent fleet for field service work. A technician photographs an equipment nameplate and describes the problem out loud, from a phone or from camera glasses.

Between every agent and the database sits the write‑gate. A proposed fact goes through cheap checks first: is the proposing agent a registered fleet member, does the value fit a 4,096‑byte cap, does the subject stay within 64 predicates. Only then does a Gemini verifier judge it against what's already known about that subject.

In the run captured for our submission gallery, the fleet made 14 proposals in 83 seconds. The gate approved 13 and refused 1: the 2022 date, with the verifier's reason quoted on screen.
