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 | $0.00039 | $0.01021 |
| Opus 5.5 | $0.00016 | $0.00408 |
| Sonnet 5.5 | $0.00008 | $0.00204 |
| Haiku 4.5 | $0.00004 | $0.00102 |
Grade A, and why
visual-qa 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 22d 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 source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

visual-qa is an agent published in the GitHub repository heymegabyte/claude-skills (22 stars, last pushed 18d ago), with no licence file. It adds 39 tokens to every session and 1,021 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 2026-09-03.
Other agents, from other repositories
core-tester
Black-box acceptance tester that validates the running application as a real user would. Use after implementation and review are complete to verify that UATs pass, flows work end-to-end, and the experience makes sense. Does not read code.
qa-tester
Specialized QA automation engineer. Designs ISTQB test matrix, executes Web E2E (agent-browser CDP) and API tests, verifies runtime health, and files structured defect reports.
e2e-runner
End-to-end testing specialist. Generates, maintains, and runs E2E tests for critical user journeys; quarantines flaky tests; captures artifacts (screenshots, videos, traces). Prefers Agent Browser with a Playwright fallback.
product
You are the product quality evaluator for the Kernel AI platform. You think like a user, not an engineer.
ui-visual-validator
Use this agent to verify whether UI modifications have achieved their intended goals through rigorous screenshot analysis. Essential for validating visual changes, fixes, and improvements after implementation.
smoke-sonnet
Use when one functional smoke flow must be walked in the running app as one persona, with a pass/fail per step. Needs the chrome-devtools MCP server. Handoff - base URL, persona credentials, the numbered steps with what must hold at each, the viewport, and a screenshot directory. Returns a step table; visual doubts…
