cleye CLI development tool — argv parsing with typed parameters, flags, commands, and auto-generated help. Use when building Node.js CLI scripts with cleye or when the user imports `cli` or `command` from `cleye`.

Strongly-typed Node.js argv parser. Schema syntax (String/Number/Boolean, arrays, custom types, aliases, defaults, single-char names), return shape (flags/unknownFlags/positional args), flag forms (long/short/grouping, = : . delimiters, kebab↔camelCase), boolean negation via `--no-`, and the `ignore` callback for multi-command dispatch. Use when working with type-flag or building CLIs on top of it (e.g. cleye).

Symlink or hardlink local packages into node_modules using `npx link`. Use when linking local dependencies for development, setting up publish-mode hardlinks, or configuring link.config.json. Do not use for general symlink/hardlink filesystem questions or npm link internals.

Create disposable file system test fixtures from objects, templates, or empty directories with automatic cleanup. Use when writing tests that need temporary files, directories, symlinks, or JSON fixtures on disk. Keywords - fs, tmp, temp, fixture, testing utility, cleanup, dispose.

Cleans package.json for npm publishing using an allowlist approach — preserves only consumer-relevant properties. Use when setting up prepack hooks, configuring npm publish workflows, or working with clean-pkg-json flags.

Evaluates JavaScript in markdown HTML comments and interpolates results in-place. Use when editing markdown files that contain mdeval script blocks or value markers, when the user wants computed/dynamic values in markdown, or when maintaining README badges, version numbers, or stats.

Manten testing library patterns - standalone imports via AsyncLocalStorage, async tests, describe groups, hooks, snapshots, timeouts, retries, and concurrency. Use when writing tests with manten, running node test files, or setting up a no-config test suite.

Usage patterns and API reference for md-pen. Use when formatting markdown strings programmatically.

Opinionated ESLint configuration and CLI for TypeScript, Vue, React, JSON, YAML, and Markdown. Use when linting code, fixing style issues, or configuring ESLint in projects using lintroll.

Manages npm package publish settings — listing packages, viewing/updating access controls, linking trusted publishers, adding maintainers, and generating OTP codes. Use when automating npm package configuration, setting up trusted publishers for provenance, managing 2FA publishing access, or bulk-updating npm packages.
