Updating Internal Documentation

Review internal documentation files against the actual codebase state and propose fixes for outdated, incorrect, or missing information.

When to use

After significant codebase changes (new features, refactors, tooling updates)
When documentation drift is suspected
After updating make targets, folder structure, dependencies, skills, or workflows
When a PR adds or modifies Streamlit features — check if bundled skills (lib/streamlit/.agents/skills/) need updates

Key files to check

Priority files (most likely to contain codebase-specific instructions):

**/AGENTS.md - AI agent instructions
**/README.md - Package/directory documentation
.claude/skills/*/SKILL.md - Skill definitions for Streamlit library development
.claude/agents/*.md - Subagent definitions
wiki/**/*.md - Developer wiki
CONTRIBUTING.md - Contributor guide
lib/streamlit/.agents/skills/*/SKILL.md - Bundled skills for Streamlit app development (shipped with the library)
lib/streamlit/.agents/skills/*/references/*.md - Reference docs for bundled skills

Files to skip (synced copies, updated separately):

.github/copilot-instructions.md
.github/instructions/*.md
.cursor/rules/*.mdc

Verification checklist

Bundled skills and feature changes

When a PR adds or changes a Streamlit feature (new widget, API change, deprecation, new capability), check if the bundled skills need updates:

Reference docs in lib/streamlit/.agents/skills/developing-with-streamlit/references/ — update the relevant existing reference to document the new feature or API change

Common triggers for bundled skill updates:

New st.* commands or widgets
Parameter changes to existing commands
Deprecated APIs or patterns (add warnings, remove outdated examples)
New layout or theming capabilities
Performance-related changes (caching, fragments)

Quick verification commands

# Check path exists: test -e path && echo ok || echo missing
# Check URL reachable: curl -sI -o /dev/null -w "%{http_code}" <url>

Tool version sources

Tool	Config file
TypeScript, React, Vite, Vitest, ESLint, oxfmt, Emotion	`frontend/package.json`
Yarn	`frontend/package.json` (`packageManager` field)
Python, Ruff, mypy, pytest	`pyproject.toml`
Node.js	`.nvmrc`

Issue types

Type	Description
OUTDATED	Info no longer accurate (old make targets, renamed files)
INCORRECT	Factually wrong (wrong paths, invalid commands)
VERSION_MISMATCH	Documented version differs from actual
MISSING	Important info not documented
BROKEN_LINK	Links to non-existent resources
INCONSISTENT	Conflicts with other docs

Workflow

Enumerate: Find all markdown documentation files
Verify: Cross-reference documented commands, paths, and examples against the codebase
Report: Present findings grouped by priority
Fix: Apply changes after user approval

Presenting findings

List all issues and let the user choose which to fix:

Documentation Review: {SCOPE}
═══════════════════════════════════════════════════════════════

Found {N} issues across {M} files:

1. [OUTDATED] AGENTS.md:42
   Current:  `make python-check`
   Actual:   Command renamed to `make python-lint`

2. [INCORRECT] wiki/testing.md:15
   Current:  Tests in `lib/tests/unit/`
   Actual:   Path is `lib/tests/streamlit/`

3. [BROKEN_LINK] CONTRIBUTING.md:88
   Current:  Link to `./docs/setup.md`
   Actual:   File does not exist

Which issues should I fix?
Recommended: "all"
Options: "1" | "1,2,3" | "all" | "skip 3"

Rules

Verify before proposing: Always check the codebase before suggesting a fix
Minimal changes: Only change what's actually wrong
Test commands: Run commands before documenting them
Keep style consistent: Match existing documentation style

After completing review

Present all findings to user
Get approval before making changes
Apply fixes incrementally
Run /checking-changes to validate

Example summary:

Fixed 3 of 4 issues:

- #1 [OUTDATED]: Updated make command in AGENTS.md
- #2 [INCORRECT]: Fixed test path in wiki/testing.md
- #3 [BROKEN_LINK]: Removed dead link in CONTRIBUTING.md
- #4 [INCONSISTENT]: Skipped - requires manual verification
