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 existential-birds/beagle at d1a74899fb.

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

About this skill

The urlsession-code-review skill, created by existential-birds, is designed to analyze code specifically related to URL session handling. It helps developers identify potential security vulnerabilities and logic errors within their backend implementations. By focusing on this critical area, the skill ensures that session management adheres to best practices for data integrity and user safety.

When to use it

  • Reviewing backend codebases where user authentication relies heavily on URL parameters or session tokens.
  • Auditing existing endpoints to ensure they properly validate session state before processing requests.
  • Identifying injection flaws or token leakage risks in dynamic routing configurations.
  • Integrating into CI/CD pipelines to automatically scan new commits for session-related regressions.

Key capabilities

  • Specialized analysis of URL parsing and session reconstruction logic.
  • Detection of insecure direct object references (IDOR) within session flows.
  • Identification of missing or weak token validation mechanisms in request handlers.
  • Flagging potential race conditions during session creation or renewal processes.

Example prompts

"Analyze this Python Flask route for vulnerabilities related to URL session manipulation." "Review the provided Node.js middleware and check for improper handling of session cookies in the URL path." "Scan this Go backend service for any insecure session token exposure via query parameters."

Tips & gotchas

This skill is specialized for backend code; ensure your input contains relevant server-side logic rather than frontend assets. While it excels at finding session-specific issues, complex business logic errors unrelated to URL handling may require broader review tools.
