gstack Document Release: Never Ship Stale Docs Again

Documentation lag is the dirty secret of most software teams. Every release updates the code. Not every release updates the docs. Over time, the README describes the old architecture, the API docs reference parameters that no longer exist, and the setup guide still recommends the deprecated configuration option.

Users hit this constantly. Developers who are new to the codebase hit it. You hit it yourself when you return to a project after three months away. Stale documentation is a tax on everyone who touches the software.

gstack's Document phase runs after every release. Its job: ensure the documentation reflects what actually shipped.

Why Documentation Falls Behind#

Documentation gets stale for structural reasons, not laziness:

The incentive gap: Shipping features is visible and celebrated. Updating documentation is invisible and expected. The ratio of recognition to effort is worse for docs.

The timing problem: The best time to update documentation is immediately after building a feature, while the context is fresh. But the PR is already open, the feature is working, and updating docs feels like adding scope at the finish line.

The scope problem: Knowing what needs updating requires understanding everything the change touches. A function signature change might require updates in the README, the API reference, the migration guide, and three separate tutorial pages.

The freshness problem: Nobody likes reading documentation. Nobody enjoys writing documentation that nobody will read. The motivation to keep docs fresh is low.

gstack's Document phase addresses all four by making documentation updates part of the automated release process.

What gstack Document Reviews#

After a release, the Document phase reviews:

README:

• Installation instructions still accurate?
• Environment variables documented and current?
• Getting started steps work with the current codebase?
• Configuration options reflect current reality?

API Reference:

• All current endpoints documented?
• Parameters, types, and return values accurate?
• Deprecated endpoints marked appropriately?
• New endpoints added since the last docs update?

Changelog:

• Does the changelog reflect all changes in this release?
• Are breaking changes prominently marked?
• Is the entry clear to someone who hasn't been following the development?

Setup/Configuration Guides:

• Environment setup steps still correct?
• Dependencies and versions accurate?
• Known issues section current?

Code Comments and Docstrings:

• Are there functions/classes with outdated comments?
• Are there new public APIs without documentation?

The Document Phase Workflow#

The Document phase compares the current state of the codebase against the documentation and identifies gaps:

1. Parse the code changes in the release: What functions changed signatures? What new APIs were added? What old APIs were deprecated or removed?

2. Find the documentation references to those code paths: Where does the README mention these functions? Where does the API reference document these endpoints?

3. Generate a diff: What's changed in the code that isn't reflected in the documentation?

4. Propose updates: For each documentation gap, generate the proposed update.

5. Present for review: The engineer reviews the proposed documentation updates, edits as needed, and approves.

6. Commit with the release: Documentation updates are committed as part of the release commit, not as a separate "update docs" commit that never gets merged.

Real Examples of What It Catches#

Here are the types of documentation issues gstack Document commonly finds:

Changed function signature: Before: createContact(name, email) After: createContact(name, email, { phone, company })

API reference still shows the old two-parameter signature. Any external integration that reads the docs will be written incorrectly.

New environment variable: The feature requires ENRICHMENT_API_KEY but the .env.example and README setup section don't mention it. New developers will encounter an unexplained failure.

Deprecated config option: Code now ignores legacy_export_format: true but the configuration guide still recommends it. Users will set it and wonder why it has no effect.

New CLI command: A new --dry-run flag was added to the import command. The CLI reference page doesn't document it. Users won't discover it unless they read the source code.

Changed default behavior: The default page size changed from 20 to 50. The pagination documentation says the default is 20. Users relying on the documentation will be surprised.

AI-Generated Documentation#

For new features that have no documentation at all, gstack Document generates first-draft documentation from the code:

• For a new API endpoint: generate the endpoint documentation from the route handler and its TypeScript types
• For a new configuration option: generate the configuration reference from the option definition and its usage in the code
• For a new CLI command: generate the command documentation from the argument parser and its help strings
• For a new class or module: generate a module overview from its exports and docstrings

The generated documentation is a first draft — it requires human review and polish. But "review and polish a first draft" is significantly faster than "write from scratch," and ensures the documentation actually exists.

Documentation Quality Standards#

gstack's Document phase doesn't just check for coverage — it checks for quality:

For API documentation:

• Each parameter has a description and a type
• The description explains what the parameter does, not just what it is
• Edge cases are documented (what happens when this is null? what's the maximum length?)
• Examples are present for complex parameters

For setup guides:

• Each step has a "verify this worked" check
• Error messages for common failures are documented
• The happy path is complete from zero state to working application

For READMEs:

• The first paragraph explains what this is and who it's for
• The quickstart works in under 5 minutes on a clean machine
• The features section is accurate and current

Integrating with the Release Process#

gstack Document runs after Ship and before the PR is merged:

Develop → Engineering Review → QA → Ship (PR opened) → Document → PR Review → Merge → Canary

The documentation updates are included in the same PR as the code changes. This means:

• Documentation review is part of code review
• Documentation updates don't get deferred to a follow-up PR
• The release and its documentation are atomic — they ship together or not at all

Frequently Asked Questions#

How does gstack Document handle docs that live in a separate repository?#

gstack can operate across multiple repositories. For documentation repositories (separate docs site, external wiki), it opens a PR in the docs repository as part of the release process, synchronized with the code repository PR.

What if the generated documentation is wrong?#

Review it. The Document phase generates first drafts, not final copy. The engineer reviews, corrects inaccuracies, and approves before merging. The AI generates; the human verifies.

Should every minor release update documentation?#

For every change that has user-visible behavior (new feature, changed default, updated API, deprecated option), yes. For internal refactors with no user-visible changes, documentation updates are optional but still worth reviewing.

How do you handle documentation for features that aren't released yet?#

Mark them clearly as "coming soon" or keep them in a separate docs/preview/ branch. The Document phase can distinguish between public-facing documentation (what users see now) and preview documentation (what's coming).

What's the best documentation format for gstack compatibility?#

Markdown files in the repository work best. They're version-controlled alongside the code, diff cleanly, and can be rendered anywhere. GitHub-flavored Markdown with frontmatter for metadata is the standard DenchClaw uses.
