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.

About this skill

What it does

The TypeScript Strict Migrator skill enables AI agents to incrementally migrate TypeScript codebases to stricter compiler options, ultimately improving type safety and reducing potential runtime errors. It follows a phased approach, enabling flags one at a time and providing guidance on fixing resulting errors. The skill helps teams systematically adopt best practices for more robust and maintainable TypeScript projects.

When to use it

  • When you want to improve the type safety of an existing TypeScript codebase.
  • For teams looking to gradually adopt stricter compiler options without breaking changes.
  • To automate parts of the process of migrating a project towards full tsconfig.json strict mode.

Key capabilities

  • Incremental Migration: Enables TypeScript compiler flags one at a time, minimizing disruption and allowing for focused error correction.
  • Error Correction Guidance: Provides examples and strategies for addressing type errors introduced by stricter compiler options.
  • TypeScript Configuration Management: Works with tsconfig.json files to manage the migration process.
  • Type Guard Implementation: Encourages the use of runtime type checking through type guards.
  • Utility Type Usage: Promotes leveraging TypeScript utility types for safe and effective type transformations.

Example prompts

  • "Migrate this file to Phase 1 strict mode settings."
  • "Enable strictNullChecks in my project and suggest fixes for any errors."
  • "What are the next steps after enabling noImplicitAny?"

Tips & gotchas

  • The skill requires a TypeScript project with an existing tsconfig.json file.
  • Migration should be performed incrementally, as enabling all strict flags at once can introduce many errors simultaneously.
  • Understanding of basic TypeScript concepts and type annotations is helpful for interpreting error messages and implementing suggested fixes.
