Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00133 | $0.04344 |
| Opus 5.5 | $0.00053 | $0.01738 |
| Sonnet 5.5 | $0.00027 | $0.00869 |
| Haiku 4.5 | $0.00013 | $0.00434 |
Grade C, and why
qa-e2e-ui scanned grade C with 2 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 1mo 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.

Regression evidence contract: a UI pass needs browser evidence, not only curl How it starts
The opening of the file, as written. The whole thing — 420 lines — stays where its author put it; the contents beside it link to each section on GitHub.
QA - E2E UI (live cluster)
Overview
This skill validates that the Sentinel dashboard actually works as a user experience against the real UI + API + Traefik stack. Curl checks are useful smoke gates, but they are not a substitute for browser interaction. Use Playwright and Chrome DevTools MCP whenever available to collect:
- accessibility snapshots for actionable element names and roles
- browser console messages
- network request/response evidence for UI-triggered API calls
- screenshots for visual regressions and responsive layout failures
- keyboard interaction evidence for reachable controls
services/ui/main_test.go covers handler-level behavior. This skill covers
browser-visible workflows: role-gated navigation, session transitions, forms,
filters, tables, modals, copy controls, destructive actions, public-host
defenses, and whether rendered UI data matches backend truth.
Header / CSP / lockout / secret-leak checks live in qa-e2e-security; do not
duplicate them here unless the symptom is visible in the UI.
Regression evidence contract: a UI pass needs browser evidence, not only curl or unit tests. For changed auth, role, or API-key behavior, cover both a user-identity session and a no-user-identity or denied session so role-gating regressions surface before merge. If browser automation is unavailable, report the UI result blocked.
Phase-gate rule: any change under services/ui/, services/ui/frontend/,
services/ui/static/, UI ingress manifests, or a backend path rendered by the
dashboard requires this skill. Run the same browser workflow once against the
pre-change deployment and once against the candidate deployment. A phase is
not passed by unit tests alone.
Step 1 - Confirm preconditions
Do not reinstall the platform or run codegen as part of UI QA. The live cluster is the source of truth.
kubectl config current-context | grep -qx kind-mcp-runtime \
|| { echo "Run qa-cluster-bringup first"; exit 1; }
curl -fsS -o /dev/null http://localhost:18080/ \
|| { echo "Traefik port-forward not running; run: kubectl port-forward -n traefik svc/traefik 18080:8000"; exit 1; }
./bin/mcp-runtime status
What ships with it
5 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.

qa-e2e-ui is a skill published in the GitHub repository Agent-Hellboy/mcp-runtime (6 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 133 tokens to every session and 4,344 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
