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 | $0.03885 | $0.03885 |
| Opus 5.5 | $0.01554 | $0.01554 |
| Sonnet 5.5 | $0.00777 | $0.00777 |
| Haiku 4.5 | $0.00388 | $0.00388 |
Grade A, and why
flutter-driver-mcp 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 2mo 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Welcome! If you are an AI agent (or a human new to the codebase) looking to contribute to flutter-driver-mcp, this guide provides the necessary architectural context, conventions, and workflows you need to be effective.
🧭 Design Philosophy
These six principles define the soul of the project. Every feature, error message, and API choice should reinforce them. If a change conflicts with any of these, rethink the approach.
1. Agent-First, Not Human-First
This is not a testing framework that happens to have an MCP wrapper. It is purpose-built for LLM agents. Every design decision should be evaluated through the lens of: "Does this make the agent more effective?" — not "Does this look nice in a terminal?" Human developers benefit as a side effect, but the agent is always the primary user.
2. Zero-Friction Entry
A user should go from "I have a Flutter project" to "an agent is controlling it" in one tool call. No pubspec.yaml edits, no entitlement files, no configuration steps, no validate_project pre-flight. The harness imports only dart:* and package:flutter_test — both already in every Flutter project. If you're about to add an external dependency to the harness, stop and find another way.
3. Errors That Coach
A blind error like "Widget not found" costs the agent a retry loop — burning tokens, time, and user patience. Every error in this project should answer three questions: What went wrong? Why? What should the agent try instead? Examples of this in practice:
"Target is not scrollable and is not inside a scrollable container. Use tap() instead.""App uses a custom router like GoRouter. Please use the tap() tool to navigate on-screen elements instead.""Too many elements found. Consider using a more specific finder, or pass an 'index' parameter.""Did you mean key: [<submit_btn>]?"(fuzzy match on failed finder)
When adding new handlers, always throw errors that suggest the next action. Never throw raw exceptions without context.
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-driver-mcp AGENTS.md is an instructions file published in the GitHub repository funkyfunc/flutter-driver-mcp (0 stars, last pushed 7mo ago), licensed MIT. It adds 3,885 tokens to every session, about $0.0155 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.
