1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.

“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Petdex Skill

Browse, install, and select animated "pet" mascots from the public petdex gallery. An installed pet reacts to agent activity (idle, running a tool, reviewing, error, done) across the Hermes CLI, TUI, and desktop app. This skill drives the hermes pets CLI and the display.pet config — it does not generate sprites.

When to Use

  • The user wants a desktop/terminal mascot or asks about "pets" / petdex.
  • The user wants to change, preview, or disable the active pet.
  • Diagnosing why a pet isn't showing (terminal graphics support, config).

Prerequisites

  • Network access to petdex.dev for the gallery/manifest (read-only, no auth).
  • Pillow (a core Hermes dependency) for sprite decoding — already installed.
  • For full-fidelity terminal rendering: a graphics-capable terminal (kitty, Ghostty, WezTerm, iTerm2, or sixel). Otherwise a truecolor Unicode half-block fallback is used automatically.

How to Run

Use the terminal tool to run hermes pets <subcommand>.

Quick Reference

GoalCommand
Browse the galleryhermes pets list (add a substring to filter: hermes pets list cat)
List installed petshermes pets list --installed
Install a pethermes pets install <slug> (add --select to make it active)
Set the active pethermes pets select <slug> (omit slug for a picker)
Resize the pet everywherehermes pets scale <factor> (e.g. 0.5, clamped 0.1–3.0)
Preview/animate in terminalhermes pets show [slug] [--cycle] [--state run]
Disable the pethermes pets off
Remove a pethermes pets remove <slug>
Diagnose setuphermes pets doctor

Procedure

  1. Find a pet: hermes pets list <query> and note its slug.
  2. Install + activate: hermes pets install <slug> --select.
  3. Preview it: hermes pets show (Ctrl+C to stop).
  4. Confirm setup: hermes pets doctor — shows the resolved pet, configured render mode, detected terminal graphics protocol, and effective mode.

Pets install into <HERMES_HOME>/pets/<slug>/ (profile-aware). Selecting a pet writes display.pet.slug + display.pet.enabled to config.yaml.

Configuration

Under display.pet in config.yaml:

  • enabled (bool) — master on/off.
  • slug (str) — active pet; empty = first installed.
  • render_mode — auto (detect) | kitty | iterm | sixel | unicode | off.
  • scale (float) — on-screen size of the native 192×208 frames (default 0.33, clamped 0.1–3.0). One knob resizes every surface; set it with hermes pets scale <factor>, the /pet scale slash command, or the desktop Appearance slider.
  • unicode_cols (int) — width in columns for the Unicode fallback.

Pitfalls

  • A pet only shows once one is installed AND selected (enabled: true).
  • Inside a pipe/redirect (no TTY) terminal rendering is disabled by design.
  • The petdex npm CLI installs to ~/.codex/pets; Hermes uses its own profile-scoped <HERMES_HOME>/pets/ instead — install through hermes pets.

Verification

  • hermes pets doctor reports ✓ ready when a pet is installed, selected, enabled, and Pillow is importable.
