CLI Documentation Conventions

Use this skill when documenting command-line programs for @skillit/cli.

Focus Areas

• .description() text on commands and subcommands
• .option() and --help descriptions for every flag
• .argument() descriptions for positional inputs
• .usage() strings and example help text
• Environment-variable documentation and config-surface JSDoc correlation

Routing Tags via Option Interfaces

For routing tags (@useWhen, @avoidWhen, @never), add them as JSDoc on a <PascalCommandName>Options interface in a TypeScript source file. The interface needs no properties — only the JSDoc block matters:

typescript
/**
 * @useWhen - Server advertises callHierarchyProvider capability
 * @avoidWhen - Server doesn't support call hierarchy; lsproxy will error
 * @never - NEVER invoke without verifying server supports this capability. Fix: check --help output or use `lsproxy call` to probe the server first
 */
interface CallHierarchyOptions {}

CliRefineSource discovers these interfaces via the source glob (**/*.ts) and correlates their tags onto the corresponding command in the generated skill. Create one per command that needs routing guidance; the filename is arbitrary (e.g. src/command-options.ts). After adding the interface, re-run skillit gen to regenerate — resolveTargetLocation will now resolve and skillit refine can write tags into the interface directly.

Fix Patterns

• Describe command intent in one sentence, not just the verb
• Explain what each option changes in behavior
• Document positional arguments with expected format or values
• Mention env vars explicitly when an option supports them
