Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is musabekisakov-imj/flutter-design-engineer's own configuration. It tells Codex and OpenCode how to work on flutter-design-engineer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything flutter-design-engineer configures →

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-design-engineer 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 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.

What it actually says

Agent Guidance

  • Treat docs/specs/2026-07-21-flutter-design-engineer-design.md as the product contract and docs/specs/2026-07-21-connected-command-center-design.md as the current showcase contract.
  • Treat docs/specs/2026-07-21-editorial-barbershop-booking-design.md as the complete mobile-journey showcase contract.
  • Treat docs/specs/2026-07-21-reproducible-workflow-benchmark-design.md as the benchmark evidence contract.
  • Treat docs/superpowers/specs/2026-07-22-flutter-product-studio-mobile-showcase-design.md as the primary mobile showcase contract.
  • Treat docs/superpowers/specs/2026-07-22-flutter-design-engineer-logo-system-design.md as the identity contract; keep SVG and Flutter mark geometry synchronized.
  • Keep every skill's frontmatter limited to name and description.
  • Keep specialist triggers distinct and route detailed knowledge to top-level references/.
  • Do not weaken the design-before-implementation or rendered-evidence gates.
  • Use apply_patch for manual edits and preserve unrelated work.
  • Run repository validation and tests after material changes.
  • Update evals when agent behavior changes.
  • Never claim compatibility, visual verification, or Flutter compilation without evidence.
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.
