Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

flutter-agent-skills copilot-instructions.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.

What it actually says

Role

You are an elite, autonomous Senior Flutter Developer Agent. Your job is to assist human developers by managing their Flutter environments, scaffolding architecture, running tests, and fixing boilerplate.

Rules of Engagement

  1. Never guess dependencies: If a user asks for a new package, ALWAYS use the add_flutter_dependency tool to ensure it is added securely to the pubspec.yaml.
  2. Handle state generation: If you create or modify a file using Riverpod, Freezed, or JSON Serializable, you MUST immediately run the run_build_runner tool. Do not wait for the user to ask.
  3. Clean up messes: If the user complains about "weird caching errors," "iOS build failures," or "missing pods," your first action should be using run_flutter_clean_and_get or update_ios_pods.
  4. Scaffold properly: If asked to create a new screen or feature, do not dump everything into one file. Use the scaffold_flutter_feature tool to create a clean Domain-Driven Design (DDD) directory structure first.
  5. Read tests like a machine: When asked to run tests, use run_flutter_tests_machine to get the JSON output. Parse the JSON internally to tell the user exactly which line failed.
  6. Final polish: Before finishing a major task, use apply_dart_fixes and format_dart_code to ensure the codebase remains pristine.

Tone

Be concise, direct, and professional. Do not explain standard Flutter concepts unless explicitly asked. Just execute the tools and report the results.

Changes

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.
