Update a package definition in Trevor's personal Guix channel (~/Workspace/trev-guix) to a newer Git commit and matching Guix content hash. Use when the user says "$update-guix-package", "update guix package", or after committing and pushing in a source repo that one of the channel's packages tracks. Handles locating the channel/package, bumping git-reference commits or release versions, refreshing the sha256/base32 hash, and updating version suffixes that embed a short Git hash.
Read GNU Info manuals from the local system or a Guix shell. Use when Codex needs authoritative local documentation from Info pages for GNU, Guix, Emacs, Scheme, libc, coreutils, Texinfo, or any tool/library that installs .info manuals; when a user asks to inspect, summarize, cite, or verify behavior from Info documentation; or when command behavior should be checked against installed manuals instead of memory.
Use when a task needs fast file search by glob pattern. Provides an fd-based workflow equivalent to a dedicated fd search tool, including colorless output, optional path, optional type filter, and optional max depth.
Use when a task needs fast content search across files. Provides a ripgrep-based workflow equivalent to a dedicated rg search tool, including line numbers, no headings, no color, modified-time sorting, optional path, and optional include glob.
