Documentation Agent

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

The challenge

Documentation is written once and then quietly goes out of date. Engineers answer the same questions in chat because the page is wrong, new joiners cannot tell which page to trust, and nobody wants to own a backlog of content that ages faster than it can be reviewed.

The outcome

A merge triggers extraction through Azure Functions, Azure AI Search indexes the code and decision records, and a Microsoft Foundry agent drafts the page with every claim checked against the source. An author approves a diff before it publishes, and Microsoft Entra keeps internal detail off public surfaces.

01 — Architecture

End-to-end architecture

A merge signals that something changed. Signatures, examples and decisions are extracted, the Foundry agent drafts the page to the house template, and every claim is checked back against the source of truth. Permission trimming keeps internal detail off public surfaces, and an author approves before anything publishes.

02 — Workflow

Process & decision workflow

How a code or process change becomes a trustworthy page — detect, extract, draft and verify, then branch. A verified factual update publishes with its source linked, while a new concept or anything requiring judgement goes to an author as a diff with the open questions listed.

03 — Components

Key Microsoft components

Documentation is only useful if it is current and true — extraction, drafting, verification and publishing all stay on the Microsoft stack.

04 — AI

What the agent consumes

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

AI capabilities embedded in the agent

  • Change detection
  • Code and API extraction
  • Template adherence
  • Retrieval-augmented generation
  • Draft generation
  • Claim verification
  • Style and terminology checks
  • Diff summarisation
  • Permission-aware publishing
  • Freshness scoring
  • Gap detection
  • Workflow orchestration

AI responsibility boundaries

The agent drafts from the source of truth and links every claim to it; a named author approves anything published. It does not invent behaviour the code does not show, publish internal detail to a public surface, or mark a page reviewed on behalf of a person. Unverifiable statements are raised as questions rather than written as fact.

05 — Personalization

Personalization & evolving process

The same methodology applies to every agent in the catalog. Tune the surfaces, the documentation template, the style rules and the value model — the page structure stays identical.

Audience & surface profile

Define the audiences, publishing surfaces, languages and sensitivity boundaries between internal and public content. The personas are the reader, the engineer author, the docs owner and the reviewer.

06 — Impact

Key outcomes & business impact

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

  • Docs freshnessPer mergePages update when the code does, not at release time.
  • Authoring effort−60%Engineers review a verified draft instead of a blank page.
  • Support questions−30%Fewer repeat questions answered from a stale page.
  • Claim traceability100%Every statement links to the source that supports it.
