How does Atlas ensure Julia READMEs are always up-to-date with the code?

Atlas directly analyzes your Julia module's source code using tools like lsp to enumerate APIs and read to inspect implementations. It never relies on outdated comments or memory, ensuring the documentation reflects the code's actual behavior today.

Can Atlas verify Julia code examples in the generated documentation?

Yes, Atlas uses the bash tool to execute every code sample within the generated README. This rigorous verification process ensures that all Julia examples are runnable and accurate, preventing the inclusion of broken or misleading snippets.

What Julia-specific tools does Atlas integrate with for documentation?

Atlas integrates deeply with the Julia toolchain, including Pkg (Project.toml) for environment management, Pkg.test (Test.jl) for running tests, and JuliaFormatter.jl for maintaining code style in touched files.

How does Atlas handle sensitive Julia code or proprietary information during indexing?

Atlas prioritizes privacy by allowing you to build its code index with local Ollama embeddings. This means your Julia code never leaves your local environment and is not sent to third-party servers for processing.

How much control do I have over the documentation changes Atlas proposes for my Julia module?

You have complete control. Atlas operates with permission-gated tool calls and presents a unified diff for every proposed file edit, including the new README. You must explicitly approve all changes before they are written to your Julia project.

Can Atlas help fix issues it finds while documenting my Julia code?

Yes, Atlas can identify issues like type instabilities in your Julia code during its analysis. It can then draft a plan to fix these issues or add @testset blocks to test/runtests.jl, asking for your approval before making any modifications.

Does Atlas support Julia's multiple dispatch in its documentation generation?

Absolutely. Atlas understands Julia's multiple dispatch by reading dispatch signatures and analyzing how methods are used in practice via codebase_search. This allows it to generate documentation that accurately reflects the nuances of your Julia functions.

Document a Julia Module with a README using Atlas in 2026

In 2026, Julia developers use Atlas to generate precise README documentation that reflects the current state of their module's code, not outdated specifications. Atlas achieves this by directly inspecting your Julia source files, enumerating public APIs with the lsp tool's documentSymbol operation, reading implementations, and verifying code samples with bash, all within your Project.toml environment.

How Atlas Documents Julia Modules Accurately

Atlas ensures README documentation for Julia modules is accurate and up-to-date in 2026 by directly analyzing the source code, not relying on outdated comments or specifications. It uses the lsp tool's documentSymbol operation to enumerate every public API, ensuring 100% coverage of your module's exported surface.

Atlas begins by establishing a deep understanding of your Julia module within its Project.toml environment. It employs the lsp tool's documentSymbol operation to precisely enumerate all public APIs exported by your module. This guarantees that the generated README covers the entire public surface of your code, leaving no function or type undocumented. Following this, Atlas uses the read tool to inspect the implementation details of each identified export. To further enrich the documentation with real-world usage patterns, Atlas leverages codebase_search to find how these exports are actually invoked within your codebase. This approach ensures the documentation reflects the code's current behavior and common idioms, such as multiple dispatch patterns, rather than just its theoretical design.

Julia-Specific Code Analysis and Verification for Documentation

Atlas integrates deeply with the Julia toolchain to verify documentation accuracy, ensuring code samples are runnable and reflect current behavior. In 2026, Atlas can execute Pkg.test() behind a permission prompt and apply JuliaFormatter.jl to touched files, providing a robust 360-degree verification.

To guarantee the reliability of code samples within the generated README, Atlas employs the bash tool to execute and verify every example. A code sample that has not been executed is considered a liability, so Atlas ensures each one runs successfully within your Julia environment. Furthermore, Atlas is configured to interact directly with Julia's core development tools. It can run Pkg.test() using Test.jl behind a permission prompt, allowing it to read test failures back into its planning agent. This capability helps Atlas identify and even suggest fixes for issues like type instabilities it might find or add @testset blocks to test/runtests.jl. After generating or modifying documentation, Atlas can also apply JuliaFormatter.jl to any touched source files, maintaining consistent code style across your project.

Generating and Reviewing Julia READMEs with Atlas

Atlas drafts READMEs for Julia modules by first analyzing existing documentation to match tone and structure, ensuring consistency across your project. It then uses the write tool to emit the new README, presenting a unified diff for approval before any file changes are committed, typically within 1-2 minutes.

Before generating a new README, Atlas uses the grep tool to search your repository for any existing README.md files. This step is crucial for matching the established heading structure, tone, and overall format, ensuring the new documentation integrates direct with your project's existing style. Once the content is gathered and structured, Atlas employs the write tool to generate the README, quoting real Julia signatures and file paths directly from your source code. Every edit Atlas proposes, including the new README, is presented as a unified diff. This allows Julia developers to review and approve changes before they are written to disk, providing complete control and transparency over the documentation process. Atlas can also read git branches, status, and diffs, and can stage and create commits on your behalf, streamlining the entire documentation workflow.

Ensuring Safety and Control in Atlas's Julia Documentation Workflow

Atlas prioritizes developer control and safety throughout the Julia documentation process, especially when interacting with your Project.toml environment. Every Atlas tool call is permission-gated against allow, ask, and deny rules, ensuring no action is taken without explicit approval, typically requiring 0-1 manual prompts.

Atlas is designed with robust safety mechanisms to give Julia developers full control. Before any tool, such as Pkg.test() or JuliaFormatter.jl, is executed, Atlas checks against predefined allow, ask, and deny rules. This permission-gating ensures that sensitive operations within your Project.toml environment are never run without your explicit consent. Atlas operates with a clear separation between its read-only plan agent, which drafts a strategy, and its build agent, which executes actions. It always asks for approval before switching to the build agent. Furthermore, Atlas computes a unified diff for every file edit, including changes to documentation or source code, and surfaces it for your approval before writing. For privacy-conscious Julia teams, Atlas can build its code index with local Ollama embeddings, keeping your proprietary code off third-party servers.

Step by step

01Run atlas in your Julia package directory containing Project.toml and Manifest.toml.
02Allow Atlas to read your module's exported methods, dispatch signatures, and the [deps] and [compat] entries from Project.toml.
03Instruct Atlas to enumerate the module's public API using the lsp tool's documentSymbol operation.
04Approve Atlas to read the implementation of each export and use codebase_search to find real-world usage patterns within your Julia project.
05Let Atlas grep the repository for an existing README.md to match its heading structure and tone.
06Approve Atlas to write the new README.md, quoting real Julia signatures and file paths, and then review the unified diff for approval.
07Grant permission for Atlas to bash execute and verify every code sample within the generated documentation.
08Optionally, allow Atlas to run Pkg.test() using Test.jl to validate module functionality and apply JuliaFormatter.jl to any touched source files.
