Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00988 |
| Opus 5 | $0.00008 | $0.00494 |
| Sonnet 5 | $0.00003 | $0.00198 |
| Haiku 4.5 | $0.00002 | $0.00099 |
Grade A, and why
petdex scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 Nyxora CLI, TUI, and desktop app. This skill drives the nyxora 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.devfor the gallery/manifest (read-only, no auth). - Pillow (a core Nyxora 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 nyxora pets <subcommand>.
Quick Reference
| Goal | Command |
|---|---|
| Browse the gallery | nyxora pets list (add a substring to filter: nyxora pets list cat) |
| List installed pets | nyxora pets list --installed |
| Install a pet | nyxora pets install <slug> (add --select to make it active) |
| Set the active pet | nyxora pets select <slug> (omit slug for a picker) |
| Resize the pet everywhere | nyxora pets scale <factor> (e.g. 0.5, clamped 0.1–3.0) |
| Preview/animate in terminal | nyxora pets show [slug] [--cycle] [--state run] |
| Disable the pet | nyxora pets off |
| Remove a pet | nyxora pets remove <slug> |
| Diagnose setup | nyxora pets doctor |
Procedure
- Find a pet:
nyxora pets list <query>and note itsslug. - Install + activate:
nyxora pets install <slug> --select. - Preview it:
nyxora pets show(Ctrl+C to stop). - Confirm setup:
nyxora pets doctor— shows the resolved pet, configured render mode, detected terminal graphics protocol, and effective mode.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
