Update docs

Update Documentation for Branch Changes

Review all changes on the current branch compared to a base branch and update markdown documentation files to reflect those changes.

Base branch: Use $ARGUMENTS if provided, otherwise default to main.

Process

1. Understand the Changes

Start by identifying what changed on the current branch:

• Run git diff <base>...HEAD --stat to see which files changed
• Run git log <base>..HEAD --oneline to understand the commit history

Then fully read and explore every changed source file (not just tests or assets) until you completely understand the changes. The diff alone does not provide enough context — you must read the full files to understand how the changes fit into the surrounding code, what patterns are used, and what the code actually does.

For each changed source file:

• Read the entire file (or at minimum the complete functions/sections that were modified)
• Understand the purpose of the file and how the changes relate to its overall role
• Follow references to other files if needed to understand dependencies or shared symbols
• If a new file was added, read it completely

Build a thorough mental model of:

• What new features, modules, or capabilities were added
• What existing behavior changed
• What new files, symbols, options, or configuration were introduced
• What was removed or renamed
• How the changes interact with the rest of the codebase

2. Inventory Documentation Files

Read ALL markdown documentation files that could be affected:

• AGENTS.md (project structure, development patterns, file listings)
• README.md (features, tools, options, API reference)
• Every file in docs/ (tools, servers, clients, prompts, apps, testing, building, getting-started, etc.)

3. Identify What Needs Updating

For each documentation file, check whether the changes on the branch affect any of its content:

• Project structure listings - Do they include new files/directories?
• Feature lists - Do they mention new capabilities?
• Tool tables - Do they list new tools or note changed tool behavior?
• Option/config tables - Do they document new options or environment variables?
• Server descriptions - Do they reflect changes to server configurations?
• Related files sections - Do they reference new source files?
• Cross-references/links - Are there broken links to renamed/removed sections?
• Code examples - Are they still accurate?

4. Make Updates

Edit existing documentation files to reflect the changes. Follow these principles:

• Match existing style: Follow the formatting conventions already used in each file (table style, heading levels, link style, etc.)
• Be concise: Add only what's necessary to accurately document the changes
• Cross-reference: Link to related documentation where appropriate
• Don't over-document: Implementation details belong in code comments, not docs

5. Create New Documentation Files

If the changes introduce a major new subsystem or concept that doesn't fit neatly into existing docs, create a new file in docs/. When doing so:

• Add it to the docs/README.md index
• Add it to the AGENTS.md docs listing
• Cross-reference it from related existing docs

6. Summary

After making all changes, provide a summary listing:

• Which files were modified and what was changed
• Any new files that were created
• Any issues or ambiguities found that may need manual attention
