Automated safety checks
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

About this skill
The mgrep-code-search skill enables AI agents to perform advanced code searches across repositories using grep-like patterns. It allows for filtering results by file type, line numbers, and specific context within the codebase.
When to use it
- Locating specific functions or variables across a large monorepo quickly.
- Finding all instances of a deprecated API usage before refactoring.
- Searching for configuration patterns (e.g., environment variables) hidden in multiple files.
- Identifying lines containing specific error codes or log messages within source code.
Key capabilities
- Executes standard grep commands directly against code repositories.
- Supports regex patterns for flexible and complex search queries.
- Filters results by file extensions to narrow down relevant code.
- Returns precise line numbers and surrounding context for matches.
Example prompts
- "Find all occurrences of 'TODO' comments in Python files within the project."
- "Search for any usage of the
legacy_authfunction and show me the line numbers." - "List all JavaScript files that import the
axioslibrary."
Tips & gotchas
Ensure the AI agent has read access to the target repository before initiating a search, as it cannot scan private or inaccessible codebases. For very large repositories, consider refining your regex patterns to avoid overwhelming the context window with excessive results.
