What it does
Monitor Experiments is an agent skill from amplitude/builder-skills. Monitors all active and recently completed experiments across Amplitude projects, triages them by importance, then runs deep analysis and reporting on the most impactful ones. Use when the user asks to "check on experiments", "experiment status", "experiment review", "what experiments are running", or wants a periodic experiment health report.
Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.
When your agent uses it
- The user asks to check on experiments
- Experiment status
- Experiment review
- What experiments are running
Example prompts
- “check on experiments”
- “experiment status”
- “experiment review”
- “/monitor-experiments”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Context & Discovery
- Fetch Metadata, Metric Names & Primary Results
- Summary & Actions
- Details
What it can do on your machine
Read from SKILL.md and the folder at commit 51838c2. 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.
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.
Context cost
Monitor Experiments loads about 3.5k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 1,478 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.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,478 words (~3,469 tokens).
“Scan active and recently completed experiments, surface what needs attention, and report on the ones that matter.”

Monitor Experiments is an agent skill from amplitude/builder-skills. Monitors all active and recently completed experiments across Amplitude projects, triages them by importance, then runs deep analysis and reporting on the most impactful ones.
When should I use Monitor Experiments?
Monitor Experiments fits situations like: the user asks to check on experiments; experiment status; experiment review; what experiments are running.
How do I install Monitor Experiments in Claude Code?
Run `npx skills add amplitude/builder-skills --skill monitor-experiments -a claude-code`. Or copy the skill folder (analytics-skills/skills/monitor-experiments in amplitude/builder-skills) into .claude/skills/monitor-experiments in your project. Claude Code loads it when a task matches its description.
How do I install Monitor Experiments in Codex?
Run `npx skills add amplitude/builder-skills --skill monitor-experiments -a codex`. Or copy the skill folder (analytics-skills/skills/monitor-experiments in amplitude/builder-skills) into .agents/skills/monitor-experiments in your project. Codex loads it when a task matches its description.
Can I use Monitor Experiments in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add amplitude/builder-skills --skill monitor-experiments -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/monitor-experiments, .gemini/skills/monitor-experiments, .github/skills/monitor-experiments and .opencode/skills/monitor-experiments in your project.
