SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of getting unstuck when you are dropped into an unfamiliar codebase and need to determine where execution begins.

Core Features & Use Cases

  • Entry-point discovery across ecosystems: Guides you through common conventions for Go, Node/TypeScript, Python, Rust, JVM stacks, Ruby, and container/orchestration setups.
  • Evidence-based verification: Prompts you to confirm the candidate entry by tracing the first ~50 lines to see whether it actually performs startup/bootstrapping work.
  • Multi-binary and library-awareness: Helps identify multiple binaries (e.g., cmd/ in Go, [[bin]] in Rust) and explicitly handles projects that are libraries or frameworks with no single main.

Quick Start

Ask the skill to identify the entry point by checking the project’s stated documentation and then following the language-specific conventions for where startup code should live.

FAQPage Schema
How do I find the main entry point in an unfamiliar codebase?

To find the entry point, check the project's README documentation first, then search language-specific manifests like package.json or Docker CMD, and verify the candidate by tracing the first ~50 lines for bootstrapping logic.

How does startup tracing work for containerized apps and CLI tools?

Startup tracing for containerized apps and CLIs involves inspecting Docker CMD instructions or language convention files, then validating the execution start location by confirming the initial lines perform actual startup or bootstrapping operations.

What is the best way to locate entry points in a multi-binary Go or Rust repository?

For multi-binary repositories, locate entry points by searching for specific directory or manifest conventions like `cmd/` in Go or `[[bin]]` in Rust, which explicitly define multiple execution start locations within the same codebase.

How do I find the execution start location if the project is a library with no main function?

If the project is a library with no main function, identify the execution start location by checking package exports and framework conventions, recognizing that libraries expose entry points through public APIs rather than a single startup script.

Does entry point discovery work across Node, Python, and JVM stacks?

Yes, entry point discovery works across Node, Python, and JVM stacks by applying ecosystem-specific conventions for startup code, such as checking package.json exports, standard script directories, and framework bootstrapping patterns.

Why should I verify a stated entry point from README documentation instead of trusting it directly?

You should verify a stated entry point because README documentation can be outdated; tracing the first ~50 lines of the candidate code confirms it actually performs the expected startup or bootstrapping work before you rely on it.
