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 | $0.00057 | $0.00792 |
| Opus 5 | $0.00028 | $0.00396 |
| Sonnet 5 | $0.00011 | $0.00158 |
| Haiku 4.5 | $0.00006 | $0.00079 |
Grade A, and why
a11y 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 3d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
a11y - Accessibility Implementation
Make Flutter apps accessible to everyone. Semantic labels, screen reader support, WCAG compliance.
When to Use This Skill
- Adding semantic labels to custom widgets
- Auditing code for accessibility issues
- Testing with screen readers (TalkBack/VoiceOver)
- Fixing accessibility violations
- Implementing focus management
Quick Reference
The Four Pillars
- Perceivable - Semantic labels, contrast ≥4.5:1, text scaling
- Operable - Touch targets ≥48dp, focus order, keyboard nav
- Understandable - Clear labels, error guidance
- Robust - Semantics widget, live regions, proper roles
Key Requirements
| Check | Requirement | Test |
|---|---|---|
| Contrast | ≥4.5:1 | textContrastGuideline |
| Touch targets | ≥48×48dp | androidTapTargetGuideline |
| Labels | All interactive | labeledTapTargetGuideline |
Commands
# Audit for accessibility issues
dart run .claude/skills/a11y/scripts/check.dart
# Audit specific feature
dart run .claude/skills/a11y/scripts/check.dart --feature auth
# Generate accessibility test file
dart run .claude/skills/a11y/scripts/check.dart --generate-tests feature_name
Workflow
1. Audit
dart run .claude/skills/a11y/scripts/check.dart --feature {feature}
Look for: Images without semanticLabel, IconButton without tooltip, custom widgets without Semantics.
2. Add Semantics
Use patterns from semantics-guide.md:
- Images:
semanticLabelproperty - Icon buttons:
tooltipproperty - Custom widgets:
Semanticswrapper
3. Test
Add accessibility tests per testing-guide.md:
await expectLater(tester, meetsGuideline(textContrastGuideline));
await expectLater(tester, meetsGuideline(androidTapTargetGuideline));
await expectLater(tester, meetsGuideline(labeledTapTargetGuideline));
4. Manual Verification
Test with VoiceOver (iOS) and TalkBack (Android). All controls should be announced clearly.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

a11y is a skill published in the GitHub repository launch52-ai/flutter-template (2 stars, last pushed 6mo ago), licensed MIT. It adds 57 tokens to every session and 792 once invoked, about $0.0003 per session on Opus 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.
