Challenge

The challenge

  • Twelve business areas — orders, cost, profitability, quality and schedule — and 225 features had to come together in one system.
  • Business teams, the PMO and developers moved together, so requirements kept arriving and changing.
  • The usual SI approach — freeze requirements, go live months later — could not handle the schedule and the change at the same time.

Vibe-Ops

An AI-native delivery process

When a requirement comes in, AI drives it in a fixed order — from documents to code, release and progress records. People request, approve and check the result on screen.

Who does what

StageAI doesPeople do
RequirementAnalyzes it, drafts and files the PRDSubmit requirements, approve scope
DesignWrites dev specs and test scenarios, splits work itemsReview specs

ReleaseWrites release notes for each releaseApprove production rollout
RecordsLogs stage start/finish, dates and comments automaticallyFinal check on screen, sign off

Three principles

01

Progress is never typed by hand

Records are created when a stage actually finishes, and progress is calculated from them.

02

Scope grows only by approval

Approving a requirement approves its scope; work items exist only inside it.

03

Procedures live in AI skills

From branching to checks, MRs, merges and release notes, 16 skills make everyone follow the same order.

Ops CLI

A door that connects AI to the work

Ops CLI opens the API of the Ops system — where requirements and work items live — on the command line. People use the web screens; AI uses the CLI on the same data. With a door made for AI, AI became a participant that reads requirements and records progress itself.

AI working through the CLI (example)
# 1. Read the requirement as development context$ ops req get REQ-101# 2. File the PRD and move the requirement to approved$ ops req artifact save REQ-101 prd prd.md$ ops req status REQ-101 APPROVED "PRD filed"# 3. Split it into work items$ ops dev add --process PRC-01 --title "Quote list screen" --type SCREEN$ ops dev add --process PRC-01 --title "Quote history API" --type API# 4. Record each stage — progress is calculated from here$ ops dev stage step DEV-201 BUILD DOING$ ops dev stage step DEV-201 BUILD APPROVE

How we opened it safely

Irreversible actions stay human

Deleting and revoking approvals are not in the CLI — people do them on the web.

Only within assigned work

AI can write only to the items assigned to its user.

Tokens never exposed

Auth tokens are passed so they never appear on the command line or process list.

Order enforced by the server

A stage can't start until the previous one is finished.

Open a CLI on a business system and AI can take part in that work. The Reboot Agent demo applies the same idea to sales, service and finance.
