AI-generated docs are the new bottleneck in development
AI coding assistants now draft specifications, architecture documents, changelogs, and README updates in seconds. But there’s a catch: someone still has to judge the quality of all that output.
A year ago, developers spent days writing specs, receiving comments, revising, then implementing code that would go through review. Today, agents generate first drafts of design docs, API references, runbooks, and onboarding guides almost instantly. Code implementation and code review can now be handled by agents, leaving only one bottleneck: document review. A human must read thousands of lines of auto-generated markdown and decide what’s wrong.
Why review is harder than it looks
The writing part has sped up dramatically, but judging quality remains a human task. LLMs can assist with document review, yet the asymmetry persists: every agent-assisted project now accumulates a stack of documents waiting for human judgment. If multiple agent loops run in parallel—one for the spec, one for the implementation plan, one for the test strategy—review becomes a pipeline stall.
GitHub pull requests remain the right tool for third-party review, but local self-review of AI-generated drafts doesn’t fit that process. Branching, diffing, and assigning reviewers is overkill for a first draft created in seconds.
The limits of natural-language feedback
Teams often rely on agents to fix documents based on natural-language feedback like “The error handling in section 3.2 is too vague.” While this seems efficient, several issues arise. Position is ambiguous—if section 3.2 has three paragraphs about error handling, the agent guesses which one the reviewer meant. Context is lost because the reviewer saw a rendered document with Mermaid diagrams, tables, and highlighted code blocks, but the prose feedback carries none of that. Round-trips are vague: the agent applies a fix, the reviewer checks the updated draft, and another guessing round begins.
The core problem is that prose feedback discards the reviewer’s mental model of the document’s structure.
A better way: structured, machine-readable feedback
What if reviewer comments came back as structured JSON, anchored to precise locations in the source markdown? Tools like MDXG Redline make this possible. Reviewers select text ranges in a rendered document, leave inline comments, and export them as structured data. This preserves context, eliminates ambiguity, and enables agents to apply fixes with full precision.
As AI accelerates development, the next bottleneck isn’t code—it’s the review of the documentation that enables it.
