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 | $0.03276 | $0.03276 |
| Opus 5.5 | $0.01310 | $0.01310 |
| Sonnet 5.5 | $0.00655 | $0.00655 |
| Haiku 4.5 | $0.00328 | $0.00328 |
Grade A, and why
fiftyone-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 today.
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 — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FiftyOne Skills - Agent Instructions
This repository contains skills for computer vision workflows using FiftyOne and the FiftyOne MCP Server.
Available Skills
FiftyOne App Playwright (fiftyone-app-playwright/)
Use when driving the FiftyOne App via the Playwright MCP — plugin/operator verification, demo or screencast recording, or any end-to-end UI automation against fo.launch_app(...). Covers the critical "do not navigate after reload_dataset" crash, launcher patterns (remote=True, trigger-file IPC), MUI-specific input/dropdown gotchas, sidebar tag filtering, data-cy selectors, dialog scrolling, session refresh strategies, and cleanup. Trigger on mentions of "Playwright + FiftyOne", "automate FiftyOne App", "operator demo", "browser_navigate crash", "reload_dataset", or any FiftyOne session that silently dies after a UI action.
Compatibility: Requires the Playwright MCP server and a Python environment with fiftyone installed (drives a live fo.launch_app(...) session).
Instructions: Load the skill file at skills/fiftyone-app-playwright/SKILL.md
FiftyOne Code Style (fiftyone-code-style/)
Writes Python code following FiftyOne's official conventions. Use when contributing to FiftyOne, developing plugins, or writing code that integrates with FiftyOne's codebase.
Instructions: Load the skill file at skills/fiftyone-code-style/SKILL.md
FiftyOne Create Notebook (fiftyone-create-notebook/)
Creates Jupyter notebooks for FiftyOne workflows including getting-started guides, tutorials, recipes, and full ML pipelines. Use when creating notebooks, writing tutorials, building demos, or generating FiftyOne walkthroughs covering data loading, exploration, inference, evaluation, and export.
Instructions: Load the skill file at skills/fiftyone-create-notebook/SKILL.md
FiftyOne Dataset Curation (fiftyone-dataset-curation/)
End-to-end dataset curation for FiftyOne: inspect schema and quality, audit annotations, analyze class distributions, explore embeddings, find duplicates, create curated subsets, and build train/val/test splits. Works with any computer vision dataset type.
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.
