What is source-linked documentation?

Last updated August 2026

Source-linked documentation is technical documentation where every material claim points back to a verifiable originating source, such as a pull request, ticket, Slack thread, design doc, or call note, so readers and AI agents can check the evidence.

Why it matters for engineering teams

Hand-written wikis fall out of date because upkeep never keeps pace with a moving codebase. When docs drift, onboarding slows, on-call answers get risky, and AI tools that summarize stale pages amplify the problem. Source-linking makes generated documentation trustworthy enough to use in production workflows.

Core characteristics

• Citations are first-class: claims link to PRs, tickets, threads, or files
• Updated from work: docs track merges, closed tickets, and decisions in chat
• Human confirmation: teams approve what agents should treat as settled
• Agent-ready: the same cited record can be queried over MCP

How source-linked documentation works

1. Connect tools: index systems where work already happens (for example GitHub, Linear, Slack)
2. Stamp decisions: capture claims with who decided and where it came from
3. Ask with proof: people and agents retrieve answers that open the original sources

FAQ

Is source-linked documentation the same as RAG?

Related, but not identical. RAG retrieves chunks for an answer. Source-linked documentation also requires that published claims remain attached to checkable origins.

Who is it for?

Engineering and product teams that need current context for onboarding, on-call, delivery handoffs, and AI coding agents.
