# Document a module with a README in Godot with Atlas in 2026

> Atlas helps Godot developers in 2026 create accurate READMEs by analyzing live GDScript code and node paths, ensuring documentation reflects current module behavior.

Atlas empowers Godot developers in 2026 to generate precise README documentation for modules by directly analyzing the current codebase, ensuring the documentation reflects the actual behavior of GDScript, node trees, and signals. It leverages tools like `lsp` for API enumeration, `read` for implementation details, and `codebase_search` for practical usage, all while respecting your existing `gdformat (gdtoolkit)` and `GUT (Godot Unit Test)` setup.

## Key takeaways

- Atlas generates Godot READMEs directly from live code, ensuring current accuracy.
- Atlas uses the `lsp` tool to enumerate Godot module APIs comprehensively.
- Code samples in Godot documentation are verified for execution with `bash`.
- Atlas integrates direct with Godot's toolchain, including `gdformat (gdtoolkit)` and `GUT (Godot Unit Test)`.
- Atlas provides transparent review with unified diffs and permission-gated actions for Godot projects.

## How to enumerate Godot module APIs for documentation with Atlas?

Atlas precisely enumerates a Godot module's public API surface in 2026 using the `lsp` tool's `documentSymbol` operation, ensuring no exported function or property is missed or invented. This process guarantees that the generated documentation accurately reflects the module's current interface, including GDScript methods and exported variables.

To produce documentation that describes what the code actually does today, Atlas begins by enumerating the module's public API. It utilizes the `lsp` tool's `documentSymbol` operation, which provides a structured view of all exported declarations within your Godot project's `.gd` scripts. This method ensures that every public function, variable, and signal is identified directly from the source, preventing any omissions or fabrications. By indexing code through AST declarations using tree-sitter, Atlas gains a deep understanding of the Godot codebase, including how GDScript interacts with the node tree and signals, ensuring the API surface is fully captured and traceable to the actual code.

## How Atlas understands Godot GDScript implementation and usage?

To document what Godot code actually does today, Atlas reads the implementation of each enumerated export using its `read` tool and then employs `codebase_search` to find how callers actually use it in practice. This dual approach provides a comprehensive understanding of module behavior, moving beyond theoretical design to real-world application in 2026.

After enumerating the public API, Atlas delves into the actual implementation and usage patterns within your Godot project. It uses the `read` tool to examine the source code of each export, understanding its internal logic. Crucially, Atlas then employs `codebase_search` to find real-world examples of how these exports are called and utilized across your codebase. This includes analyzing GDScript files, identifying node paths accessed via `$` or `get_node()`, and understanding the role of autoload singletons defined in `project.godot`. This ensures that the documentation reflects the module's practical behavior and common usage scenarios, rather than just its intended design from a year ago.

## How Atlas writes a README for a Godot module and matches existing style?

Atlas generates the README for a Godot module using its `write` tool, first `grep`ping the repository for an existing `README.md` to match its heading structure and tone rather than inventing a new format. This ensures consistency with your project's documentation standards, providing a familiar experience for developers in 2026.

When it's time to write the README, Atlas prioritizes consistency and adherence to your project's existing documentation style. Before generating new content, Atlas uses the `grep` tool to search your repository for an existing `README.md` file. This allows it to analyze and adopt the established heading structure, tone, and overall format. Once the style is understood, Atlas employs its `write` tool to construct the new README, quoting real GDScript signatures, actual file paths, and concrete examples derived from its analysis of your Godot codebase. This approach ensures the documentation is not only accurate but also direct integrates with your project's existing aesthetic.

## How Atlas verifies code samples in Godot documentation?

Every code sample included in the generated Godot documentation is rigorously verified by Atlas using the `bash` tool, ensuring that each snippet is executable and accurate in 2026. A sample that was never executed is considered a liability, so Atlas runs them to confirm their functionality within your Godot project context.

Accuracy in documentation extends beyond descriptions to runnable code. Atlas takes a critical step to verify every code sample it includes in the generated Godot documentation. Using the `bash` tool, Atlas executes these snippets to confirm their functionality and correctness within your project's environment. This verification process is vital because a code sample that has not been executed is a potential source of error and frustration for developers. By running the samples, Atlas ensures that the documentation provides reliable, working examples that Godot developers can trust and integrate into their own `.gd` scripts.

## What are Atlas's review and safety features for Godot documentation?

Atlas incorporates multiple safety and review mechanisms for Godot documentation, including a read-only plan agent that drafts a plan before switching to a build agent, and computing a unified diff for every file edit. This ensures that all proposed changes, like adding a new `README.md` or modifying `.gd` scripts, are transparent and require explicit approval in 2026.

Atlas is designed with robust safety and review features to give Godot developers full control over documentation changes. Before any modifications are made, Atlas drafts a plan in a read-only plan agent, which you must approve before it switches to a build agent. Every Atlas tool call, including `lsp`, `read`, `codebase_search`, `grep`, `write`, and `bash`, is permission-gated against allow, ask, and deny rules. For every file edit, such as creating a new `README.md` or modifying existing `.gd` scripts, Atlas computes a unified diff and surfaces it for your approval. Atlas also reads git branches, status, and diffs, and can stage and create commits on your behalf, providing snapshots of file changes as git patches so edits can be diffed and rolled back, ensuring complete transparency and control over your Godot project.

## Steps

1. Run Atlas in your Godot project by navigating to the root directory containing `project.godot` and executing `atlas`.
2. Let Atlas index your Godot codebase: Atlas automatically reads your `.gd` scripts, identifies node paths accessed with `$` or `get_node()`, and understands autoload singletons from `project.godot` settings.
3. Ask Atlas to enumerate the module's public API: Atlas uses the `lsp` tool's `documentSymbol` operation to list all exported functions, variables, and signals.
4. Instruct Atlas to read implementation and usage: Atlas employs the `read` tool for code details and `codebase_search` to find practical calls within your Godot project.
5. Have Atlas `grep` for existing README style: Atlas searches for `README.md` files to match the established heading structure and tone.
6. Ask Atlas to `write` the new README: Atlas generates the `README.md` content, incorporating real GDScript signatures and file paths.
7. Review and approve Atlas's proposed changes: Examine the unified diff for the new `README.md` and any touched `.gd` scripts, then grant approval.
8. Let Atlas verify code samples: Atlas uses the `bash` tool to execute and confirm the accuracy of all code snippets in the documentation.
9. Optionally, let Atlas run `gdformat`: After documentation, Atlas can run `gdformat (gdtoolkit)` over any touched GDScript files for consistent formatting.
10. Commit the changes: Atlas can stage the new `README.md` and any modified `.gd` scripts, then create a commit on your behalf.
