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 | $0.00524 | $0.00524 |
| Opus 5 | $0.00262 | $0.00262 |
| Sonnet 5 | $0.00105 | $0.00105 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
pet-forge CLAUDE.md 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 7d 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.

pet-forge Agent Notes
This file is the short entry point for AI coding agents working in this repository. Keep user-facing docs public-safe: no personal names, local machine paths, private project paths, private handles, or unpublished asset references.
Project
pet-forge is a toolkit for building custom desktop pets. It provides two independent output routes:
SVG Route
Output: self-contained .svg.html files.
- Local vector workflow: reference image -> background removal -> PNG to SVG -> preset/template -> CSS/JS animation.
- Best for precise loops, low file size, and hand-tuned animation.
- Main folders:
routes/svg/presets,routes/svg/templates,routes/svg/conventions,routes/svg/tools/png2svg.
APNG Route
Output: .apng frame animations.
- Generation workflow: prompt template -> reference image -> video generation with first/last-frame anchoring -> chroma key -> APNG.
- Best for fast rich visual exploration when API reruns are acceptable.
- Main folders:
routes/apng/prompts,routes/apng/conventions,routes/apng/tools.
Public-Repo Rules
- Do not add personal names, account handles, emails, local usernames, or absolute local paths.
- Do not reference private checkouts as if public users can access them.
- Do not commit
.env, generated outputs, caches, ornode_modules. - Keep character/product assets separate from this toolkit unless they are explicitly licensed for inclusion.
- Keep quick-start commands runnable from the paths shown.
Design Boundaries
The toolkit does not:
- manage external API keys or billing;
- decide final aesthetics for a user;
- include finished character assets;
- guarantee one-click generation of a complete pet.
The toolkit does:
- provide route-specific workflows;
- document loop/state conventions;
- provide APNG generation/post-processing scripts;
- provide SVG templates/presets;
- describe a generic desktop-pet state map.
Current Status

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.

pet-forge CLAUDE.md is an instructions file published in the GitHub repository rullerzhou-afk/pet-forge (48 stars, last pushed yesterday), licensed MIT. It adds 524 tokens to every session, about $0.0026 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
