SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents documentation from drifting away from the actual implementation by generating and maintaining technical docs based on the code that exists today.

Core Features & Use Cases

  • Full generation per domain: Creates a consistent documentation set (overview, architecture, API, data model, workflows, and UI components when applicable) for a specified domain.
  • Incremental updates after changes: Detects recently modified code and updates only the impacted documentation sections, adding an update note with the date.
  • Coherence audits: Verifies that documented references still exist and that signatures/interfaces and workflows still match the current code, producing a structured audit report.

Use case example: After refactoring an API controller in a backend domain, run an update to refresh only the affected endpoint and workflow documentation, then run an audit to ensure no new services went undocumented.

Quick Start

Run feature-doc in Audit mode for the domain you want to validate, so the generated report highlights what is OK, what is desynchronized, and what is missing.

Frequently Asked Questions about feature-doc

FAQPage Schema
How do I keep technical documentation in sync with my codebase after refactoring?

To keep technical documentation in sync with your codebase, this Skill detects recently modified code and incrementally updates only the impacted documentation sections, adding a timestamped update note. It generates overview, architecture, API, data model, and workflow docs directly from the current code.

What is a documentation coherence audit and how does it verify code references?

A documentation coherence audit verifies that documented references still exist and that signatures, interfaces, and workflows still match the current code. It produces a structured audit report highlighting what is synchronized, what is desynchronized, and what is missing.

Can I generate full domain documentation for an entire backend service?

Yes, you can generate full domain documentation for a backend service. This Skill creates a consistent documentation set covering overviews, architecture, APIs, data models, workflows, and UI components when applicable, driven by YAML frontmatter identification and code scanning.

How do I audit existing API documentation to find missing endpoints and services?

To audit existing API documentation for missing endpoints, run this Skill in Audit mode for your target domain. It scans code by domain and patterns, traces workflows, and generates a structured report verifying that all documented references and signatures match the current implementation.

Does this documentation tool require specific setup to identify files in my codebase?

Yes, this documentation tool requires YAML frontmatter-driven identification to locate and scope files within your codebase. It uses adaptive context loading via manifests and stack patterns to ensure deterministic doc file synthesis and accurate code scanning.

What is the best way to update only the affected workflow docs after changing an API controller?

The best way to update affected workflow docs after changing an API controller is using incremental updates. This Skill detects the recently modified code, refreshes only the impacted endpoint and workflow documentation sections, and verifies no new services went undocumented through a coherence audit.
