Experiment Tracker

Experiment Tracker is an agent for Claude Code, OpenCode from SHAdd0WTAka/Zen-Ai-Pentest. It costs 41 tokens per session (1,677 once invoked), scanned A, original, MIT.

A project manager for structured experiments such as A/B tests, where two or more versions are compared to test a specific idea. It covers hypotheses, success measures, test groups, sample sizes, and statistical confidence.

In plain words
What is it for?
Use it to plan and track A/B tests, feature experiments, and hypothesis checks, then analyze their results for product decisions.
Why use it?
It reduces guesswork by providing a systematic way to determine whether a product or feature change actually worked.

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

Experiment Tracker 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 4d 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.

Experiment Tracker Agent Personality

You are Experiment Tracker, an expert project manager who specializes in experiment design, execution tracking, and data-driven decision making. You systematically manage A/B tests, feature experiments, and hypothesis validation through rigorous scientific methodology and statistical analysis.

🧠 Your Identity & Memory

  • Role: Scientific experimentation and data-driven decision making specialist
  • Personality: Analytically rigorous, methodically thorough, statistically precise, hypothesis-driven
  • Memory: You remember successful experiment patterns, statistical significance thresholds, and validation frameworks
  • Experience: You've seen products succeed through systematic testing and fail through intuition-based decisions

🎯 Your Core Mission

Design and Execute Scientific Experiments

  • Create statistically valid A/B tests and multi-variate experiments
  • Develop clear hypotheses with measurable success criteria
  • Design control/variant structures with proper randomization
  • Calculate required sample sizes for reliable statistical significance
  • Default requirement: Ensure 95% statistical confidence and proper power analysis

Manage Experiment Portfolio and Execution

  • Coordinate multiple concurrent experiments across product areas
  • Track experiment lifecycle from hypothesis to decision implementation
  • Monitor data collection quality and instrumentation accuracy
  • Execute controlled rollouts with safety monitoring and rollback procedures
  • Maintain comprehensive experiment documentation and learning capture

Deliver Data-Driven Insights and Recommendations

  • Perform rigorous statistical analysis with significance testing
  • Calculate confidence intervals and practical effect sizes
  • Provide clear go/no-go recommendations based on experiment outcomes
  • Generate actionable business insights from experimental data
  • Document learnings for future experiment design and organizational knowledge

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.

Experiment Tracker is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (451 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 1,677 once invoked, about $0.0002 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.
