Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned patricio0312rev/skills at 79ea6af485.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The Codebase Summarizer analyzes a code repository to generate comprehensive architecture documentation. It recursively scans the folder structure, identifies key patterns and frameworks used, maps entry points like main files and APIs, traces data flow between layers (controllers, services, models), documents individual modules, creates "how-to" guides for common tasks, and generates visual diagrams using Mermaid syntax. The output is structured as an ARCHITECTURE.md file containing a system overview, tech stack details, high-level architecture diagram, project structure breakdown, key component descriptions, data flow sequences, request lifecycles, and examples of common patterns.

When to use it

  • When onboarding new developers to a complex codebase.
  • To quickly understand the overall architecture of an unfamiliar project.
  • For generating documentation as part of a continuous integration/continuous delivery (CI/CD) pipeline.
  • To create "how-to" guides for common development tasks within the project.
  • When needing to communicate the codebase structure and key components to stakeholders.

Key capabilities

  • Recursive Folder Scanning: Analyzes directory structures to understand organization.
  • Pattern Detection: Identifies frameworks, architecture styles, and key directories.
  • Entry Point Mapping: Locates main files, routes, APIs, and CLI commands.
  • Data Flow Tracing: Visualizes request flow through application layers.
  • Module Documentation: Explains the purpose and responsibilities of each directory.
  • Navigation Guide Creation: Generates "how-to" guides for common tasks.
  • Mermaid Diagram Generation: Creates visual architecture diagrams.
  • Documentation Structure: Produces a standardized ARCHITECTURE.md file with sections for overview, tech stack, architecture diagram, project structure, key components, data flow, and request lifecycle.

Example prompts

  • "Summarize the codebase in this repository."
  • "Generate an ARCHITECTURE.md document for this project."
  • "Show me a diagram of the application's high-level architecture."

Tips & gotchas

  • The skill generates documentation based on code structure and patterns; it may require manual review and adjustments to ensure accuracy and completeness.
  • The generated Mermaid diagrams are dependent on correct syntax within the codebase.
