Closes #1244

Type

  • Bug fix
  • New feature (type:feature)
  • Documentation only
  • Maintenance

Summary

Add an optional showStats configuration boolean (default: true) to BannerConfig that allows users to toggle the runtime info panel (stats table) on/off while keeping the calligraphy logo and rose artwork intact:

  • Non-destructive default: Defaults to showStats: true when omitted or unconfigured, preserving current startup display behavior and all existing test assertions 100%.
  • Config & Commands:
    • Added gentle:toggle-stats command to toggle showStats and persist to banner.json.
    • Added Stats: on/off item to the interactive gentle:banner selection menu.
    • Updated visual profiles validation in lib/visual-profiles.ts to accept banner profiles with or without showStats.
  • Documentation: Documented /gentle:toggle-stats in docs/readme-reference.md.

Verification

  • Added unit and rendering tests in tests/startup-banner.test.ts covering:
    • Defaulting to showStats: true when unconfigured.
    • Persisting and reading showStats: false.
    • Toggling via gentle:toggle-stats.
    • Rendering with showStats: false: artwork (rose and calligraphy) renders cleanly while GIT, PATH, MCP, and other stats rows are omitted.
  • Ran full test suite across banner, shell, and visual profile suites: 320/320 tests passing (0 failures).
  • npm run typecheck: 0 diagnostics, no regressions.

Summary by CodeRabbit

  • New Features
    • Added a setting to show or hide the startup statistics panel, enabled by default.
    • Added the /gentle:toggle-stats command to switch the panel on or off. When hidden, the rose and logo can remain visible.
  • Documentation
    • Added the toggle command to the commands reference.

📝 Walkthrough

Walkthrough

The startup banner configuration adds a stats visibility setting. A new command toggles and persists that setting. The banner renders runtime statistics according to the setting and existing display conditions.

Changes

Startup Stats Panel

Layer / File(s) Summary
Stats configuration and validation
extensions/startup-banner.ts, lib/visual-profiles.ts
BannerConfig adds optional showStats, enabled by default. Configuration normalization and edit reads handle the field, and visual profile validation accepts it when boolean.
Stats toggle command
extensions/startup-banner.ts, tests/startup-banner.test.ts, docs/readme-reference.md
The banner menu and gentle:toggle-stats command toggle and persist showStats. The command notification reports its effective state. Tests cover the default and toggle behavior. The command reference documents the toggle.
Conditional stats rendering
extensions/startup-banner.ts, tests/startup-banner.test.ts
The render cache key includes the effective stats setting. Runtime statistics render only when enabled and when the existing intro or logo conditions are met. A test checks that disabling stats leaves the rose visible and hides the listed runtime rows.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e6065

For existing configurations, the first “Stats: on” menu selection does not turn the panel off. Fix that toggle and add the required visual-profile tests before merging.

Explanation

Issue #1244 requirements are met for the showStats default, config loading and persistence, stats-only rendering control, gentle:toggle-stats, menu support, and automated tests. The source sets showStats to true by default and gates only the stats table. The README diff documents /gentle:toggle-stats, but it does not document the new showStats configuration option required by #1244.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Toggle the effective stats setting in the banner menu.

If an existing banner.json omits showStats, the menu displays “Stats: on”, but this line sets showStats to true. The first selection leaves the stats panel on. Negate config.showStats ?? DEFAULT_BANNER_CONFIG.showStats, as the toggle command does.

Add tests for the changed visual-profile validation.

The existing visual-profile tests cover the legacy banner shape, but they do not cover acceptance of boolean showStats or rejection of non-boolean showStats. Add those cases to exercise parseVisualProfilesFile through the validator path.

Assert that the text logo remains visible.
