Scaffold / maintain CLI help (cli.help.ts)

This skill applies the typed root help pattern used across @finografic CLI tools (genx, gli, and scaffolds from genx).

Read first (repo — canonical for this repository)

• .agents/instructions/project/cli-help-patterns.instructions.md — rules, file locations, HelpConfig shape, examples/footer conventions.

Deeper spec (canonical — in this repo)

• docs/spec/CLI_CORE.md — full core/render-help API (HelpConfig, renderHelp, section shapes), export table, and examples.

Optional context: A temporary bulk-task folder in a monorepo (e.g. ___REFACTORING___) may hold REPORT_CLI_NORMALIZATION.md with migration history. That path is not canonical; use it when you have it for background, not as the spec.

Keep this skill procedural; link to docs/spec/CLI_CORE.md for authoritative types and tables.

Prerequisites

• src/core/render-help/ exists (shared module; do not rewrite the renderer unless intentionally changing core/ across all CLI repos).
• tsconfig.json includes "core/*": ["./src/core/*"] (or equivalent).
• You know the CLI binary name (e.g. genx) and the commands to list.

Procedure

1. Open or create src/cli.help.ts at the repository root of src/ (never nested under commands/ for root help).

2. Import types from the barrel only:

   import type { HelpConfig } from 'core/render-help';

   Do not import help types from src/types/ or utils/.

3. Export a single named config cliHelp (not default export):

   export const cliHelp: HelpConfig = {
     main: { bin: '…', args: '<command> [options]' },
     // commands, examples, footer — see instruction file
   };

4. Follow section conventions (details in the instruction file):
   • examples: label = human description, description = exact command line.
   • footer: label may use <placeholder> tokens; description optional dim line.
5. Wire src/cli.ts: import renderHelp from core/render-help and cliHelp from ./cli.help.js (use .js extension if the project uses verbatimModuleSyntax). Call renderHelp(cliHelp) only from the CLI entry / help branch — not inside cli.help.ts.
6. Optional shared defaults: genx uses defaultHelpOptions from config/help.config for minWidth / alignment — follow existing project pattern if present.
7. Verify: pnpm typecheck and run the binary with --help or no args to confirm layout.

When adding a new command

• Add a row to commands.list (keep descriptions one line).
• Add Examples entries where users will copy-paste real invocations.
• Update any command-specific help files (src/help/*.help.ts) if this repo splits per-command help — root skill covers root HelpConfig only.

Design constraints

• Root help stays declarative data (HelpConfig); rendering is centralized in core/render-help.
• Do not duplicate renderHelp logic in application code.
