Hex Personal Transformations

This skill targets current Hex (dev builds now, and the next stable release). Hex 2.3.1 uses an older runtime; its matching skill installs with npx skills add anomalyco/hex#app-v2.3.1 --skill hex-personal-commands.

Hex runs ~/.config/hex/hex.config.ts itself, in an embedded JavaScript engine. There is no package to install and no build step.

1. Check for ~/.config/hex/hex.config.ts (or hex.config.js). If it is missing, ask the user to open Hex's Modes pane and choose Create Config, or run hex commands init if the hex CLI is available.
2. Read ~/.config/hex/AGENTS.md for the current API and limits, and hex.d.ts for exact types. Hex owns both and rewrites them; do not edit them.
3. Edit only the config and files it imports. Scripts are plain TypeScript or JavaScript: they can import @hex/commands and files in the folder, not npm packages, Effect, or Node APIs, and they have no filesystem, network, or timer access. Enums, namespaces, and constructor parameter properties are rejected.
4. Use defineHexConfig from @hex/commands and declare pure transformations entries ({ id, name, description?, transform(text, context) }).
5. Transformations must be selected in the mode's Transformations section. They run after mode corrections and optional AI rewriting, not for meetings.
6. Run hex commands check (macOS) after editing. It loads the config as Hex does and prints what it registers or the error with file, line, and column. Optionally type-check with npx -y -p typescript tsc in ~/.config/hex. A running Hex reloads the config on save and shows load errors in Modes' Transformations section. If hex reports commands check as an unrecognized subcommand, stop: the user is on an older Hex (such as 2.3.1). Tell them to install the matching skill with npx skills add anomalyco/hex#app-v2.3.1 --skill hex-personal-commands, or to switch to the dev build (https://github.com/anomalyco/hex#downloads).

Completion criterion: the requested behavior is represented in the config, hex commands check succeeds (or, without the CLI, the reload succeeded in Hex), and any verification gap is reported.
