# Document a Module with a README in Clojure with Atlas in 2026 > Clojure developers in 2026 use Atlas to generate README documentation directly from source code, ensuring accuracy and relevance. In 2026, Clojure developers leverage Atlas to produce precise README documentation by directly analyzing their `deps.edn` projects, ensuring the generated content accurately reflects the current state of the code, not outdated specifications. Atlas integrates direct with the Clojure toolchain, employing the `lsp` tool for API enumeration, the `read` tool for implementation details, and the `grep` tool for existing README structure, all while respecting your project's `cljfmt` conventions. ## Key takeaways - Atlas uses the `lsp` tool to accurately enumerate Clojure module APIs from `deps.edn` projects. - The `read` and `codebase_search` tools capture real Clojure code behavior and usage patterns. - Atlas employs `grep` to ensure new READMEs match existing Clojure project documentation style. - The `bash` tool verifies Clojure code samples in documentation, preventing outdated examples. - Atlas provides unified diffs and permission prompts for safe, reviewable Clojure documentation updates. - Atlas integrates `cljfmt` to maintain consistent formatting for Clojure code blocks in READMEs. ## How Atlas Enumerates Clojure Module APIs for Documentation In 2026, Atlas precisely enumerates a Clojure module's public API using the `lsp` tool's `documentSymbol` operation, ensuring no exported function or macro is overlooked. This method guarantees that the documentation reflects the actual surface area of your `src/my_project/core.clj` namespace. Atlas begins the documentation process for a Clojure module by invoking the `lsp` tool's `documentSymbol` operation. This capability allows Atlas to query the Language Server Protocol for a definitive list of all public declarations within a given Clojure namespace, such as those defined in `src/my_project/utils.clj`. Unlike methods that might infer APIs from comments or file names, `documentSymbol` provides a verified, real-time enumeration of what the code actually exports. This ensures that every public function, macro, or var in your `deps.edn` project is accounted for in the generated README, preventing omissions or the inclusion of non-existent entities. The result is a foundational understanding of the module's interface, directly derived from the Clojure source code itself, forming the basis for accurate and comprehensive documentation. ## Capturing Real Clojure Code Behavior and Usage with Atlas To ensure documentation describes what the code actually does today, Atlas employs the `read` tool to analyze Clojure implementation details and `codebase_search` to find practical usage examples. This dual approach, critical in 2026, captures the nuances of how functions like `my-project.core/process-data` are truly utilized across your `deps.edn` project. After enumerating the API, Atlas delves into the actual behavior of each Clojure export. It uses the `read` tool to parse and understand the implementation logic of functions and macros within files like `src/my_project/logic.clj`. Concurrently, Atlas leverages `codebase_search` to scan the entire `deps.edn` project for real-world invocations of these exports. This is crucial for understanding how Clojure developers are actually threading pipelines with `->>` or defining `deftest` cases in `test/my_project/core_test.clj` that exercise the module. By combining direct code analysis with practical usage patterns, Atlas generates documentation that accurately reflects the current operational reality of the Clojure code, rather than relying on potentially outdated design specifications or developer assumptions. This ensures the README is a living document, always synchronized with the codebase. ## Structuring and Generating Clojure READMEs with Atlas Atlas ensures new Clojure READMEs maintain consistency by first using the `grep` tool to analyze existing `README.md` files for established heading structures and tone. In 2026, the `write` tool then generates the documentation, meticulously quoting real Clojure signatures and file paths like `src/my_project/api.clj` to maintain accuracy. Before generating new documentation, Atlas employs the `grep` tool to search for any existing `README.md` files within your Clojure project. This step is vital for understanding the project's established documentation style, including heading hierarchies, code block formatting, and overall tone. By matching these conventions, Atlas ensures that the new README integrates direct with your project's existing documentation ecosystem. Once the structure is determined, the `write` tool takes over, composing the README content. It directly quotes real Clojure function signatures, such as `(defn my-project.core/calculate [x y])`, and includes precise file paths like `src/my_project/data.clj`. This direct quotation of source elements, combined with the context gathered from API enumeration and usage analysis, results in a README that is both accurate and stylistically consistent with your `deps.edn` project. ## Verifying Clojure Code Samples and Reviewing Atlas Edits In 2026, Atlas rigorously verifies every Clojure code sample within the generated README by executing it with the `bash` tool, preventing the inclusion of non-functional examples. All proposed changes are presented as a unified diff for approval, and `cljfmt` is applied to maintain consistent formatting across your `deps.edn` project. A critical step in Atlas's documentation workflow is the verification of code samples. After drafting the README, Atlas uses the `bash` tool to execute every Clojure code snippet included in the documentation. This proactive measure ensures that all examples are runnable and produce the expected output, eliminating the liability of outdated or incorrect code samples. For instance, it might run `clojure -M:test` with `kaocha` to validate test cases or execute simple `clojure` commands. Before any changes are committed, Atlas presents a unified diff of all modifications to files like `README.md`. This diff is surfaced for your explicit approval, allowing you to review every line added, removed, or altered. Furthermore, Atlas applies `cljfmt` to the generated documentation, ensuring that all Clojure code blocks adhere to your project's established formatting conventions, maintaining a clean and consistent codebase. Every Atlas tool call is permission-gated, requiring your explicit consent before execution, providing a robust safety net for your `deps.edn` project. ## Steps 1. Run `atlas` in your Clojure project, ensuring it can read your `deps.edn` configuration, namespace requires, and any `:aliases`. 2. Ask Atlas to enumerate the module's public API using the `lsp` tool's `documentSymbol` operation, targeting relevant Clojure namespaces like `src/my_project/core.clj`. 3. Instruct Atlas to `read` the implementation of each Clojure export and use `codebase_search` to find how callers actually use it in practice, for example, observing `->>` threading macros. 4. Have Atlas `grep` the repository for an existing `README.md` to match heading structure and tone, then `write` the new documentation, quoting real Clojure signatures and file paths. 5. Permit Atlas to `bash` execute every Clojure code sample in the draft README to verify its correctness and functionality, potentially running `clojure -M:test` with `kaocha`. 6. Review the unified diff generated by Atlas for the `README.md` and any other changes, then approve the edits, allowing Atlas to apply `cljfmt` for consistent Clojure formatting. ## FAQ ### How does Atlas ensure Clojure documentation is always up-to-date with the code? Atlas ensures Clojure documentation is current by directly reading the source code using the `read` tool and analyzing real usage patterns with `codebase_search`. This process, performed in 2026, guarantees that the generated README reflects the actual state and behavior of your `deps.edn` project, not just what was intended a year ago. ### What specific Clojure tools does Atlas integrate with for documentation generation? Atlas integrates deeply with the Clojure toolchain.
