Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.01182 |
| Opus 5 | $0.00010 | $0.00591 |
| Sonnet 5 | $0.00004 | $0.00236 |
| Haiku 4.5 | $0.00002 | $0.00118 |
Grade A, and why
dart-collect-coverage 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 2d 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.
This is a copy
94% identical to dart-collect-coverage — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Implementing Dart and Flutter Test Coverage

Testing Fundamentals
Structure your test suites using the standard Dart testing paradigms. Use package:test for Dart projects and flutter_test for Flutter projects.
- Unit Tests: Verify individual functions, methods, or classes.
- Component/Widget Tests: Verify component behavior, layout, and interaction using mock objects (
package:mockito). - Integration Tests: Verify entire app flows on simulated or real devices.
Coverage Directives
Exclude specific lines, blocks, or entire files from coverage metrics using inline comments. Pass the --check-ignore flag during formatting to enforce these directives.
- Ignore a single line:
// coverage:ignore-line - Ignore a block of code:
// coverage:ignore-startand// coverage:ignore-end - Ignore an entire file:
// coverage:ignore-file
Workflow: Configuring and Generating Coverage Reports
Follow this sequential workflow to add the coverage package, execute tests, and generate an LCOV report.
Task Progress Checklist:
- 1. Add
coverageas adev_dependency. - 2. Execute the automated coverage script.
- 3. Validate the LCOV output.
1. Add Dependencies
Add the coverage package as a dev_dependency to your project. Do not add it to standard dependencies.
If working in a standard Dart project:
dart pub add dev:coverage
If working in a Flutter project:
flutter pub add dev:coverage
2. Collect Coverage and Generate LCOV
Use the bundled test_with_coverage script. This script automatically runs all tests, collects the JSON coverage data from the Dart VM, and formats it into an LCOV report.
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.

dart-collect-coverage is a skill published in the GitHub repository sutchan/Agent-Skills-Hub (2 stars, last pushed yesterday), licensed MIT. It adds 19 tokens to every session and 1,182 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to dart-collect-coverage, differing in 0 lines, and is treated as a copy.
