What it does

Experiment Verification Monitoring is an agent skill from hashgraph-online/awesome-codex-plugins. Verify and monitor running experiments for operational quality. Use when designing prelaunch QA, spot-check tooling, experiment canaries, A/A tests, leakage checks, interference monitoring, active experiment dashboards, alerts, or an experimentation quality roadmap.

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `guidelines.md`, `references/core/examples.md` and `references/core/knowledge.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.

It sits in DevOps & Cloud, covering A/B testing and Deployment. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • Designing prelaunch QA
  • Spot-check tooling
  • Experiment canaries
  • Interference monitoring

Example prompts

  • “/experiment-verification-monitoring”

Requirements

  • Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Define the experiment quality risks the platform must catch.
  2. Add prelaunch verification for assignment, targeting, exposure, treatment,
  3. Add early launch canaries and active monitoring for misconfiguration.
  4. Run periodic A/A tests to validate infrastructure health.
  5. Track quality metrics and update the experimentation playbook.
  6. Define owners and escalation paths for active experiment issues.

What it can do on your machine

Read from SKILL.md and the folder at commit 3e1456a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Codex, Claude Code, and other Agent Skills-compatible clients.

    From compatibility in the SKILL.md frontmatter.

Context cost

Experiment Verification Monitoring loads about 771 tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 232 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~771
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Experiment Verification Monitoring

Use this skill to prevent misconfigured or unhealthy experiments from producing bad evidence. It focuses on verification before launch, canaries, A/A tests, leakage and interference checks, active monitoring, and quality roadmap metrics.

Source Traceability

Primary source: Next-Level A/B Testing by Leemay Nassery. Guidance is transformed and paraphrased from Chapter 5 on experiment effectiveness, prelaunch verification, QA tooling, canaries, A/A tests, spillover effects, and active monitoring.

Related skills:

  • ab-test-design-brief for planning an experiment before verification.
  • experimentation-throughput-strategy for monitoring overlap conflicts.
  • trustworthy-experiment-insights for statistical credibility after results.

Workflow

  1. Define the experiment quality risks the platform must catch.
  2. Add prelaunch verification for assignment, targeting, exposure, treatment, metrics, and user experience.
  3. Add early launch canaries and active monitoring for misconfiguration.
  4. Run periodic A/A tests to validate infrastructure health.
  5. Track quality metrics and update the experimentation playbook.
  6. Define owners and escalation paths for active experiment issues.

# Experiment Verification And Monitoring Plan

## Quality Risks
[What errors or trust failures this plan should prevent.]

## Prelaunch Checks
| Check | Method | Owner | Pass/Fail Criteria |
|-------|--------|-------|--------------------|

## Active Monitoring
- Canary:
- Dashboards:
- Alerts:
- Leakage/interference checks:

## Platform Health
- A/A test cadence:
- Quality metrics:
- Review process:

## Escalation Rules
- Pause if:
- Restart if:
- Investigate if:

Quality Bar

  • Do not rely on manual QA alone when the platform has recurring setup errors.
  • Do not launch experiments without verifying assignment, exposure, and metrics.
  • Do not treat A/A tests as one-time setup checks; use them as periodic health checks when platform trust matters.
  • Do not monitor only final results; active tests need early health signals.
