live-system-verification

live-system-verification is a skill for Claude Code, Codex from paruff/uFawkesAI. It costs 65 tokens per session (1,053 once invoked), scanned A, original, MIT.

A verification skill that starts the affected software in a real environment and checks acceptance criteria through actual HTTP requests and process behavior. It is intended for cases explicitly marked for live-system testing.

In plain words
What is it for?
It brings up real dependencies, runs live acceptance checks, and records evidence from the running application.
Why use it?
It finds problems that mocked or simulated tests can hide. The resulting evidence reflects how the running system actually behaves.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

live-system-verification 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 6d 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.

Live System Verification Skill

Why this exists

test.md mocks at every boundary by default — a reasonable rule for unit and integration tests, but it means those tests can pass while the actual deployed system does not work. This skill is the deliberate exception: no mocks, real running dependency, real evidence.

⚠️ Environment target — CONFIRM before using

This skill is written substrate-agnostic on purpose because the actual target environment was not confirmed at time of writing:

  • If uFawkesPipe: a docker-compose.yml was observed alongside its .woodpecker.yml/Jenkinsfile — this may be a usable substrate for standing up real dependencies. Confirm before relying on it.
  • If uFawkesObs: no deploy-target evidence was available. Fill in Step 1 below with your actual mechanism (docker-compose, kind/k3d ephemeral cluster, existing staging namespace, or something else) before using this skill for real.

Do not run this skill until Step 1 is filled in for your actual stack.

Step 1 — Stand up the environment

<FILL IN: the exact command(s) to bring up a real, running instance of the component(s) under test for your stack. Examples of what this might look like, NOT prescriptions — verify against your own infra before using any of these:docker compose -f docker-compose.yml up -d, or applying GitOps overlays to an ephemeral kind/k3d cluster, or akubectl apply -k overlays/ephemeral/. Do not guess at your own command from this list — confirm it works locally before wiring it into this skill.>

Wait for readiness (health check endpoint, docker compose ps showing healthy, or equivalent) before proceeding. Record the readiness check and its output as evidence.

Step 2 — Run the tagged tests

Run only the tests placed in the tests/live/ (or tests_live/) directory per test.md's file placement convention, against the real endpoints/services now running from Step 1. Examples of what these assertions typically look like — verify current syntax for whichever tool you actually adopt, do not assume these exact names are installed:

live-system-verification is a skill published in the GitHub repository paruff/uFawkesAI (2 stars, last pushed 17d ago), licensed MIT. It adds 65 tokens to every session and 1,053 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 2026-09-03.
