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.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.01325
Opus 5.5	$0.00022	$0.00530
Sonnet 5.5	$0.00011	$0.00265
Haiku 4.5	$0.00006	$0.00133

Security

Grade A, and why

flutter-test-strategy 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.

Flutter Test Strategy

Overview

Flutter Test Strategy defines lowest-layer test placement (Unit, Widget, Golden, Integration), per-package coverage ratchets, concise IEEE/ISTQB docs/<feature-name>/test-matrix.md (<= 80 lines), and Fail-Honest execution proof across Claude Code and Google Antigravity—complementing dart-add-unit-test, flutter-add-widget-test, flutter-add-widget-preview, flutter-add-integration-test, dart-generate-test-mocks, and dart-collect-coverage.

When to Use

Trigger Scenarios

Choosing between Unit, Widget, Golden, and Integration tests for a Flutter feature or bugfix.
Authoring Tier 2/3 docs/<feature-name>/test-matrix.md (<= 80 lines) or calibrating per-package LCOV gates.

When NOT to Use

Mock or individual test mechanics: Use dart-generate-test-mocks or flutter-add-widget-test once the layer is chosen.
Non-Dart backend suites: Use test-driven-development or testing-expert.

Process

flowchart LR
    A["Change / US-AC"] --> B["Lowest Layer: Unit | Widget | Golden | Integration"]
    B --> C["Scoped TDD Loop (Assigned Test Only)"]
    C --> D["Full Suite + LCOV Ratchet"]
    D --> E["test-matrix.md (<=80 lines) + Exit 0 / BLOCKED"]

1. Layering Rule & Design Contract Alignment

Inspect root AGENTS.md (<= 90 lines wired to context/memory/MEMORY.md), official Google root DESIGN.md (<= 110 lines 2-layer YAML + 8 sections), and optional ## Design in docs/<feature-name>/spec.md (<= 30 lines screen delta). Test at the lowest layer that catches the defect (see references/test-pyramid-flutter.md):

Unit (package:test): Domain rules, DTO mappers, Notifier/Bloc transitions with fake repos.
Widget (WidgetTester): Loading/empty/error/data branching, user gestures, 48x48dp & Semantics.
Golden: Pixel/theme/text-scale fidelity against root DESIGN.md tokens (flutter-add-widget-preview).
Integration (integration_test/): Critical multi-screen flows (auth, checkout) on simulator/device/Chrome.
Exclusions: Never write dedicated tests for generated files (*.g.dart, *.freezed.dart, *.gr.dart) or trivial getters.

What ships with it

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-test-strategy is a skill published in the GitHub repository jggomez/expert-ai-developer-skills (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 55 tokens to every session and 1,325 once invoked, about $0.0002 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 2026-11-06.
