mkt-experimentAutonomous growth experimentation framework. An agent skill from evolution-foundation/evo-nexus.
Mkt Experiment is an agent skill from evolution-foundation/evo-nexus. Autonomous growth experimentation framework. Creates A/B/multivariate experiments with hypotheses, logs data points, runs statistical analysis (bootstrap CI + Mann-Whitney U), auto-promotes winners to a living playbook, and suggests next experiments. Use when creating or managing marketing experiments, logging data points, scoring experiments, or generating weekly scorecards.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `README.md`, `autogrowth-weekly-scorecard.py` and `experiment-engine.py`).
It sits in Marketing & SEO, covering A/B testing and Statistics. The repository describes itself as: The open source operating system for AI-powered businesses.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 7f5dd76. It shows what the files ask for, not the result of running them.
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.
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
python3pipFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
PIPELINE_AUTH_TOKENRECRUITING_AUTH_TOKENEMAIL_AUTH_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Mkt Experiment loads about 1.2k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 382 words of instructions outside code blocks.
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.
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.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 382 words (~1,213 tokens).
“Autonomous growth experimentation framework based on Karpathy's autoresearch pattern applied to marketing. Creates experiments with hypotheses, logs data points, runs statistical analysis (bootstrap CI + Mann-Whitney U), auto-promotes winners to a living playbook, and suggests next experiments. Supports batch mode…”

Autonomous growth experimentation framework. An agent skill from evolution-foundation/evo-nexus. Mkt Experiment is an agent skill from evolution-foundation/evo-nexus. Autonomous growth experimentation framework.
Mkt Experiment fits situations like: managing marketing experiments; logging data points; scoring experiments; generating weekly scorecards.
Run `npx skills add evolution-foundation/evo-nexus --skill mkt-experiment -a claude-code`. Or copy the skill folder (.claude/skills/mkt-experiment in evolution-foundation/evo-nexus) into .claude/skills/mkt-experiment in your project. Claude Code loads it when a task matches its description.
Run `npx skills add evolution-foundation/evo-nexus --skill mkt-experiment -a codex`. Or copy the skill folder (.claude/skills/mkt-experiment in evolution-foundation/evo-nexus) into .agents/skills/mkt-experiment in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add evolution-foundation/evo-nexus --skill mkt-experiment -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mkt-experiment, .gemini/skills/mkt-experiment, .github/skills/mkt-experiment and .opencode/skills/mkt-experiment in your project.
Going by SKILL.md and its folder, Mkt Experiment needs Python for the scripts in its folder, the command-line tools its instructions call (python3 and pip) and credentials named PIPELINE_AUTH_TOKEN, RECRUITING_AUTH_TOKEN and EMAIL_AUTH_TOKEN. Our summary lists: Python 3; A credential in PIPELINE_AUTH_TOKEN; A credential in RECRUITING_AUTH_TOKEN.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Mkt Experiment has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
