How does Atlas ensure Astro documentation is always up-to-date?

Atlas ensures Astro documentation is current by directly reading the live source code using tools like `lsp` and `read`. It analyzes `.astro` components, `src/pages` routes, and `src/content.config.ts` schemas, guaranteeing that the README reflects the code's actual behavior today, not historical intentions.

Can Atlas document Astro components and content collections?

Yes, Atlas is designed to work direct with Astro's specific constructs. It uses `lsp documentSymbol` to enumerate exports from `.astro` islands and reads content collection schemas defined in `src/content.config.ts`, ensuring comprehensive documentation for all parts of your Astro project.

What Astro tools does Atlas integrate with for documentation?

Atlas integrates with the core Astro toolchain. It understands `astro.config.mjs` for project context, can verify code samples that might involve `pnpm` commands, and uses `prettier` with `prettier-plugin-astro` to format generated documentation, maintaining your project's style.

How does Atlas verify code examples in Astro READMEs?

Atlas verifies every code sample in the generated README by executing it with `bash`. This ensures that any `pnpm` commands, `vitest` snippets, or Astro component usage examples are functionally correct and will run as described in your Astro project.

Is it safe to let Atlas modify my Astro project files?

Yes, Atlas is designed with safety in mind. All tool calls are permission-gated, and Atlas presents a unified diff for every proposed file edit, including README updates or changes to `astro.config.mjs`. You review and approve all changes before they are written to your Astro project.

How does Atlas handle existing README files in an Astro project?

Atlas can `grep` your repository for an existing `README.md` file. This allows it to analyze the current heading structure, tone, and style, and then generate new documentation that maintains consistency with your project's established documentation practices for Astro.

Document an Astro Module with a README in 2026 using Atlas

In 2026, Atlas helps Astro developers produce accurate, up-to-date documentation for modules by reading live source code, leveraging tools like `pnpm` for package management, `vitest` for testing, and `prettier` with `prettier-plugin-astro` for formatting, ensuring READMEs reflect current implementation, not outdated plans. This process guarantees that every claim in your documentation is traceable directly to the codebase.

How Atlas Enumerates Astro Module APIs for Documentation

Atlas precisely enumerates an Astro module's public API surface in 2026 using the `lsp` tool's `documentSymbol` operation, ensuring no export is missed or invented. This method provides a 100% accurate list of available functions, components, and data structures, directly from your `.astro` files and `src/content.config.ts` schemas.

To document an Astro module, Atlas first identifies all its public exports. It achieves this by invoking the `lsp` tool with the `documentSymbol` operation. This is crucial for Astro projects, where exports can range from components in `.astro` files to content collection schemas defined in `src/content.config.ts`. By relying on the Language Server Protocol, Atlas gets a real-time, accurate representation of the module's interface, reflecting its current state. This prevents the documentation from including deprecated exports or missing newly added ones, a common issue with manually maintained READMEs.

Reading Astro Code and Usage Patterns with Atlas

Atlas reads the implementation of each Astro export and uses `codebase_search` to understand how callers actually use it in practice, providing a 360-degree view of its behavior. This includes analyzing `src/pages` routes and content collection schemas, ensuring the documentation reflects real-world usage in 2026.

After enumerating the API, Atlas dives into the implementation details. It uses the `read` tool to parse the source code of each identified export, whether it's an Astro component or a utility function. Furthermore, Atlas employs `codebase_search` to find practical examples of how these exports are consumed across the project. This involves scanning files like `src/pages/**/*.astro` for component usage or `src/content.config.ts` for schema definitions. This dual approach ensures the documentation describes not just what the code *says* it does, but what it *actually* does in the context of the entire Astro application, preventing outdated or theoretical descriptions.

Generating Astro READMEs with Real Signatures and Paths

Atlas drafts the README for your Astro module using the `write` tool, quoting real signatures and real file paths directly from your codebase. It can also `grep` the repository for an existing `README.md` to match its heading structure and tone, ensuring consistency across your project's 2026 documentation.

When generating the README, Atlas prioritizes accuracy and consistency. It uses the `write` tool to construct the documentation, embedding actual code signatures and file paths extracted during the reading phase. Before writing, Atlas can `grep` your repository for any existing `README.md` files. This allows it to adopt a consistent heading structure, tone, and style, rather than inventing a new format. For Astro projects, this means the README will correctly reference `.astro` component paths, `src/content` collection directories, and `astro.config.mjs` configurations, making the documentation immediately familiar and useful to other Astro developers.

Verifying Astro Code Samples with `bash` for Accuracy

Every code sample included in the generated Astro documentation is rigorously verified by Atlas using `bash`, ensuring 100% accuracy. A sample that was never executed is a liability, so Atlas runs each snippet to confirm it behaves as described in your 2026 Astro project.

A critical step in producing reliable documentation is verifying code examples. Atlas addresses this by running every code sample in the drafted README using `bash`. This means if your documentation includes a snippet demonstrating an Astro component's usage or a `pnpm` command to install dependencies, Atlas will attempt to execute it. This proactive verification catches errors, outdated syntax, or incorrect assumptions before the documentation is published. For Astro developers, this guarantees that any `pnpm install` or `vitest` command shown in the README will actually work in their project, building trust in the generated content.

Atlas Safety and Review for Astro Documentation Edits

Atlas operates with robust safety mechanisms, including permission-gated tool calls and unified diffs for every file edit, ensuring full control over your Astro project's documentation. Before any changes are written, Atlas presents a clear diff for approval, allowing you to review every proposed modification in 2026.

Atlas prioritizes developer control and safety. Every Atlas tool call, including `lsp`, `read`, `write`, and `bash`, is permission-gated against `allow`, `ask`, and `deny` rules. This means Atlas will always ask for permission before executing potentially modifying actions. When drafting a README or applying formatting with `prettier` and `prettier-plugin-astro`, Atlas computes a unified diff for every file edit. This diff is surfaced for your approval, allowing you to meticulously review all proposed changes to your Astro project's documentation. Atlas can also read `git` branches and stage/create commits on your behalf, streamlining the integration of verified documentation updates.

Step by step

01Run `atlas` in your Astro project, ensuring an `astro.config.mjs` file is present for configuration context.
02Let Atlas use the `lsp` tool's `documentSymbol` operation to enumerate public exports from your `.astro` components and `src/content.config.ts` content collection schemas.
03Allow Atlas to `read` the implementation of each export and use `codebase_search` to find real-world usage examples within `src/pages` routes and other Astro files.
04Permit Atlas to `grep` your repository for existing `README.md` files to match the heading structure and tone for consistency.
05Approve Atlas to `write` the README, quoting actual code signatures and file paths relevant to your Astro project.
06Grant permission for Atlas to use `bash` to verify every code sample in the drafted README, confirming `pnpm` commands or Astro component snippets function correctly.
07Review the unified diff presented by Atlas for all proposed changes to the README and other files, such as dropping a `client:load` directive if suggested.
08Let Atlas format the new README using `prettier` with `prettier-plugin-astro` to maintain code style consistency across your Astro codebase.
09Approve Atlas to stage and create a `git` commit with the updated documentation, reflecting the current state of your Astro module.
