Software Development Agent

Software Development Agent that automates it & engineering workflows using your data and tools.

The challenge

Engineers spend the day on scaffolding, wiring and test boilerplate instead of design. Context is scattered across the codebase, old decision records and half-remembered conversations, and review queues grow because changes arrive without an explanation of why they look the way they do.

The outcome

Azure AI Search retrieves the codebase and decision records, a Microsoft Foundry agent plans the change, and Azure OpenAI implements it to the house patterns with tests. Secrets, licences and vulnerabilities are scanned before a pull request opens, and a human reviews and merges every change.

Build This Solution

01 — Architecture

End-to-end architecture

An issue is read against the codebase and its prior decisions. The Foundry agent proposes an approach, writes the change to the house patterns, generates tests and runs the security and licence scans — then opens a pull request. A human reviews and merges every change; the agent never pushes to a protected branch.

02 — Workflow

Process & decision workflow

How an issue becomes a reviewable change — understand, plan, implement, test and scan, then branch. A green, in-scope change opens a pull request with its rationale, while failing checks or scope creep stop and go to a human first. Failing checks stay visible rather than being worked around.

03 — Components

Key Microsoft components

Generated code is only safe behind real gates — retrieval, generation, testing, scanning and human review all stay on the Microsoft stack.

04 — AI

What the agent consumes

The capabilities the agent applies to every change, and the line it does not cross.

AI capabilities embedded in the agent

  • Codebase retrieval
  • Requirement interpretation
  • Change planning
  • Code generation
  • Test generation
  • Static analysis
  • Secret and licence scanning
  • Vulnerability detection
  • Diff summarisation
  • Pull-request drafting
  • Flow metrics
  • Human review routing

AI responsibility boundaries

The agent proposes changes through a pull request; a human reviews and merges every one. It does not push to a protected branch, widen scope beyond the issue, weaken a test to make a build pass, or commit a secret. Failing checks stay failing and visible rather than being worked around.

05 — Personalization

Personalization & evolving process

The same methodology applies to every agent in the catalog. Tune the codebase, the change template, the quality gates and the value model — the page structure stays identical.

Codebase & standards profile

Define the repositories, languages, architecture patterns, house style and decision records in scope. The personas are the developer, the reviewer, the tech lead and the security engineer.

06 — Impact

Key outcomes & business impact

Starting targets for the value case — validate each one against the customer baseline during discovery.

  • Change lead time−40%A tested, explained change is waiting when review starts.
  • Time on boilerplate−70%Scaffolding, tests and wiring stop consuming the day.
  • Review focusDesignReviewers judge the approach, not the formatting.
  • Change traceability100%Every change carries its rationale, tests and approver.
