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 | $0.01022 | $0.01022 |
| Opus 5.5 | $0.00409 | $0.00409 |
| Sonnet 5.5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
flutter-skills AGENTS.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 1mo 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contributing skills
This repo hosts open-source Agent Skills developed at Chunky Tofu Studios, focused on AI-assisted Flutter development. Consumers should read README.md; this file is for anyone — human or agent — adding or editing a skill here.
If you're new to Agent Skills, start with the canonical docs and come back:
- Specification —
SKILL.mdformat, frontmatter fields, directory layout. - Quickstart — minimal working skill in one file.
- Best practices — what makes a skill effective.
- Optimizing descriptions — the
descriptionfield is the trigger; this is how to tune it. - Using scripts in skills — script conventions, error handling, structured output.
skill-creator— Anthropic's practical reference for writing and iterating on skills end-to-end.
The rest of this doc is just the conventions specific to this repo.
Repo conventions
Layout. Each skill lives at skills/<skill-name>/, where <skill-name> exactly matches the name field in its SKILL.md. Bundle helpers under scripts/, on-demand docs under references/, and templates/fixtures under assets/ — per the spec.
Frontmatter. In addition to the required name and description fields, set:
license: MIT
metadata:
author: Chunky Tofu Studios
source: https://github.com/chunkytofustudios/flutter-skills
license: MIT ensures consumers who pull a skill standalone still see the repo license. metadata.source lets them find updates.
Register the skill in two places. When adding a new skill:
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.

flutter-skills AGENTS.md is an instructions file published in the GitHub repository ChunkyTofuStudios/flutter-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 1,022 tokens to every session, about $0.0041 per session on Opus 5.5. 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 2026-08-31.
