# Document a Module with a README in Groovy with Atlas in 2026 > Atlas ensures Groovy module documentation is accurate by directly reading source code, enumerating APIs, and verifying code examples with `Spock (gradle test)`. Atlas empowers Groovy developers in 2026 to produce precise module documentation by directly analyzing current source code, rather than relying on outdated specifications. It leverages the `lsp` tool to enumerate public APIs, reads implementation details, and uses `codebase_search` to understand real-world usage, ensuring the generated README reflects what the code actually does today. This process integrates direct with the Groovy toolchain, including `Gradle` for dependency management, `Spock (gradle test)` for verification, and `Spotless` for formatting. ## Key takeaways - Atlas uses `lsp` to precisely enumerate Groovy module APIs, ensuring comprehensive documentation. - Documentation reflects current Groovy code behavior and actual usage, not outdated specifications. - `Spock (gradle test)` is used by Atlas to verify Groovy code examples within the READMEs. - `Spotless` ensures consistent Groovy formatting for both code and documentation. - Atlas provides granular control with permission prompts and unified diffs for all Groovy file changes. - Groovy code and context remain local with Atlas's Ollama embeddings, enhancing privacy. ## How does Atlas document Groovy modules accurately in 2026? In 2026, Atlas documents Groovy modules by directly inspecting the codebase, ensuring the README reflects the current state of the code, not a year-old plan. It uses the `lsp` tool's `documentSymbol` operation to enumerate every public API, guaranteeing 100% coverage of exported surfaces. Atlas's approach to documenting Groovy modules is rooted in its ability to read and understand the actual source code. Instead of relying on stale comments or external specifications, Atlas uses its `lsp` tool to perform a `documentSymbol` operation. This operation precisely enumerates the real exported surface of a Groovy module, ensuring that no public API is missed or invented in the documentation. For instance, if your `src/main/groovy/MyService.groovy` defines a new public method, Atlas will identify it. This capability is crucial for Groovy projects that might evolve rapidly, ensuring that the documentation always mirrors the current implementation. Atlas builds its code index with local Ollama embeddings, keeping your Groovy code off third-party servers while providing deep semantic understanding. ## What Groovy tools does Atlas integrate with for README generation? Atlas integrates deeply with the Groovy ecosystem, leveraging familiar tools like `Gradle` for project structure, `Spock (gradle test)` for verifying code examples, and `Spotless` for consistent formatting. This ensures that the generated READMEs are not only accurate but also adhere to established Groovy project standards in 2026. When documenting a Groovy module, Atlas doesn't operate in a vacuum; it embraces the existing Groovy toolchain. For instance, it expects to run in a project containing a `build.gradle` file or a `Jenkinsfile`, allowing it to understand project dependencies and build logic. After drafting a README, Atlas can be prompted to run `./gradlew test` to execute `Spock` specifications, verifying any Groovy code samples included in the documentation. This step is permission-gated, requiring your explicit approval before execution. Furthermore, to maintain code quality and consistency, Atlas can apply `Spotless` with the Groovy formatter to any touched files, ensuring the generated documentation and code examples align with your project's formatting rules. This integration means Groovy developers can trust that Atlas-generated content fits direct into their existing workflows. ## How does Atlas ensure Groovy documentation reflects current code usage? Atlas ensures Groovy documentation reflects actual code usage by reading implementation details and observing how methods are called across the codebase. It employs the `read` tool to analyze the behavior of each export and `codebase_search` to find practical examples of how callers use these Groovy components in 2026. To move beyond theoretical descriptions, Atlas actively investigates how Groovy code is used in practice. After enumerating a module's public API, Atlas uses its `read` tool to delve into the implementation of each export, understanding its internal logic and behavior. Crucially, it then employs `codebase_search` to scan the entire repository for instances where these Groovy methods or classes are invoked. This allows Atlas to gather real-world usage patterns and common idioms, which are then incorporated into the README. For example, if a Groovy method in `src/main/groovy/com/example/Util.groovy` is consistently called with a specific parameter pattern across 5 different test files, Atlas will highlight this practical usage. This approach guarantees that the documentation is traceable to actual code and usage, providing concrete, actionable information for other developers. ## What are the safety and review steps for Atlas-generated Groovy docs? Atlas prioritizes safety and developer control throughout the documentation process for Groovy modules, offering multiple review points before any changes are committed. Every Atlas tool call is permission-gated, and it drafts a plan in a read-only agent, asking for approval before switching to a build agent to make changes in 2026. Developer control is paramount when Atlas generates documentation for Groovy projects. Before any tool, such as `write` or `bash`, is executed, Atlas presents a permission prompt based on allow, ask, or deny rules. This ensures that you, the Groovy developer, are always in control. Atlas first drafts a comprehensive plan in a read-only plan agent, detailing the steps it intends to take. You review this plan and explicitly approve it before Atlas switches to a build agent to perform any modifications. Furthermore, for every file edit, Atlas computes a unified diff and surfaces it for your approval. This allows you to meticulously review every proposed change to your Groovy files, including the new README or any code modifications, before they are written to disk. Atlas also snapshots file changes as git patches, enabling easy diffing and rollback of edits, providing a robust safety net for your Groovy codebase. ## How does Atlas verify Groovy code examples in READMEs? Atlas rigorously verifies every Groovy code sample included in the generated README by executing it with `bash`, ensuring that all examples are functional and accurate. A code sample that has never been executed is considered a liability, so Atlas's workflow includes this critical verification step in 2026. The integrity of documentation hinges on the accuracy of its code examples. For Groovy READMEs, Atlas takes this seriously by using the `bash` tool to run every code sample it includes. This means if your README contains a snippet demonstrating how to use a Groovy class or method, Atlas will attempt to execute that snippet in a shell environment. This proactive verification catches potential errors, outdated syntax, or incorrect assumptions before the documentation is finalized. For instance, if a Groovy example relies on a specific `Gradle` task or a `Spock` test setup, Atlas will attempt to run it, flagging any failures. This ensures that developers reading the README can confidently copy and paste examples, knowing they will work as described. This commitment to executable documentation significantly reduces the 'documentation rot' common in many projects. ## Steps 1. Run Atlas in your Groovy project, ensuring it can read your `build.gradle` or `Jenkinsfile` to understand the project context. 2. Ask Atlas to enumerate the module's public API using the `lsp` tool's `documentSymbol` operation, capturing all exported Groovy components. 3. Instruct Atlas to `read` the implementation of each Groovy export and use `codebase_search` to find how callers actually use it in practice across your repository. 4. Have Atlas `grep` the repository for an existing `README.md` or similar file to match its heading structure and tone, ensuring consistency with your Groovy project's style. 5. Approve Atlas's plan to `write` the new or updated `README.md` with real Groovy signatures and file paths, quoting directly from the source. 6. Allow Atlas to `bash` execute every Groovy code sample within the drafted README, verifying its functionality and catching any errors before committing. 7. Permit Atlas to run `./gradlew test` to execute `Spock` specifications, further validating the module's behavior and any related documentation claims. 8. Approve Atlas to apply `Spotless` with the Groovy formatter to the `README.md` and any other touched Groovy files, ensuring consistent code style. ## FAQ ### How does Atlas ensure my Groovy documentation is always up-to-date?
