Use when the user wants a structural, syntax-aware diff between two source files or git revisions - a diff that parses each side as code (Rust, TS, Python, Go, ...) and ignores reformatting, brace movement, or whitespace noise. Binary is difft; use for syntax-aware diffs, not plain file viewing.
EnglishUse when the user formats Java source files to a consistent style on the command line - applying Google Java Style or Android (AOSP) style, replacing files in place, or running a CI check that fails on style drift.
EnglishUse when the user wants to measure cyclomatic complexity, find overly complex functions, audit code complexity, or generate a complexity report for a codebase.
EnglishUse when the user wants to install, pin, or switch language/runtime versions per repository - node, python, go, ruby, java, rust, deno, bun, terraform, etc. - or read/write .mise.toml or .tool-versions.
EnglishUse when the user wants to run ad-hoc SQL against a database from the shell - postgres, mysql, sqlite, mssql, oracle, snowflake, bigquery, redshift, cockroachdb, clickhouse, duckdb, and 20+ more drivers via one binary. Use the universal usql client instead of psql/mysql/sqlite CLIs for ad-hoc SQL.
EnglishUse when the user wants to jump between directories by partial name on the command line - a smarter cd that learns frequently visited folders and ranks them by frecency (frequency × recency).

What’s included
Difftastic
Use when the user wants a structural, syntax-aware diff between two source files or git revisions - a diff that parses each side as code (Rust, TS, Python, Go, ...) and ignores reformatting, brace movement, or whitespace noise. Binary is difft; use for syntax-aware diffs, not plain file viewing.
Google Java Format
Use when the user formats Java source files to a consistent style on the command line - applying Google Java Style or Android (AOSP) style, replacing files in place, or running a CI check that fails on style drift.
Lizard
Use when the user wants to measure cyclomatic complexity, find overly complex functions, audit code complexity, or generate a complexity report for a codebase.
Mise
Use when the user wants to install, pin, or switch language/runtime versions per repository - node, python, go, ruby, java, rust, deno, bun, terraform, etc. - or read/write .mise.toml or .tool-versions.
Usql
Use when the user wants to run ad-hoc SQL against a database from the shell - postgres, mysql, sqlite, mssql, oracle, snowflake, bigquery, redshift, cockroachdb, clickhouse, duckdb, and 20+ more drivers via one binary. Use the universal usql client instead of psql/mysql/sqlite CLIs for ad-hoc SQL.
Zoxide
Use when the user wants to jump between directories by partial name on the command line - a smarter cd that learns frequently visited folders and ranks them by frecency (frequency × recency).
