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 | $0.00051 | $0.04099 |
| Opus 5 | $0.00026 | $0.02049 |
| Sonnet 5 | $0.00010 | $0.00820 |
| Haiku 4.5 | $0.00005 | $0.00410 |
Grade A, and why
a11y-validate 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 5d 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.

The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/a11y-validate — Accessibility & EAA Compliance Scanner
$ARGUMENTS
Scan a codebase for accessibility issues using pattern-matching heuristics. Detects violations of WCAG 2.1 Level AA, EN 301 549 (the EU harmonized accessibility standard), and the European Accessibility Act (Directive (EU) 2019/882, "EAA", in force since 28 June 2025). Read-only — never modifies files.
Complements /seo-validate (which only covers SEO-a11y overlap shallowly). Use this skill when the concern is legal accessibility compliance, not search engine ranking.
Standards basis:
- WCAG 2.1 Level A + AA — W3C Recommendation 2018 (updated 2023).
- WCAG 2.2 Level AA (opt-in via
--standard wcag-2.2-aa) — adds 2.4.11 focus not obscured, 2.5.8 target size minimum, 3.2.6 consistent help, 3.3.7 redundant entry, 3.3.8 accessible authentication. - EN 301 549 v3.2.1 — EU harmonized standard; aligned with WCAG 2.1 AA plus additional chapters for mobile, hardware, ICT procurement, authoring tools, and functional-performance statements.
- EAA / Directive (EU) 2019/882 — legal framework requiring EN 301 549 conformance for consumer-facing digital products and services in EU markets. Deadline: 28 June 2025. Requires accessibility statements per member-state templates.

What ships with it
7 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-validate is a skill published in the GitHub repository softspark/ai-toolkit (169 stars, last pushed today), licensed Apache-2.0. It adds 51 tokens to every session and 4,099 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 2026-08-30.

cline-fix-volatile-msg
Ladder-aware Cline Anthropic caching — verify the rolling read/write ladder on the wire, then add the tools breakpoint and tune TTL. Updated for the 2026-08 AI-SDK monorepo.
aider-1h-ttl
Aider uses 5min TTL by default and works around long pauses with keepalive pings. Wire up the 1h TTL beta instead.
continue-enable-defaults
Continue's prompt caching is opt-in via config and off by default. Flip the default to systemAndTools.
continue-gemini-explicit
Continue's Gemini provider doesn't use the cachedContents API at all. Add explicit caching for sessions over the minimum token threshold.
opencode-bedrock-doc-blocks
OpenCode places cachePoint on Bedrock messages containing DocumentBlocks, which produces a "nothing available to cache" error.
