| name | finding-experiments |
| description | Resolves experiment references from natural language to concrete experiment IDs. Handles name lookups, fuzzy descriptions ('the signup experiment', 'my latest experiment'), status filtering, and disambiguation when multiple experiments match.
TRIGGER when: user refers to an experiment by name, description, or relative reference ('latest', 'most recent', 'the one I created yesterday') and you don't already have the experiment ID.
DO NOT TRIGGER when: user provides an experiment ID directly, or you already resolved the experiment earlier in the conversation. |
Finding experiments
Users refer to experiments by name, description, or relative references — not by ID.
This skill resolves natural language references to concrete experiment IDs.
How to find an experiment
Use the experiment-list tool from the Posthog-local MCP server.
IMPORTANT: Do NOT use feature-flag-get-all or any feature flag tool to find
experiments. Use the dedicated experiment list tool: experiment-list.
This tool returns experiments with their id, name, status, feature_flag_key,
start_date, end_date, and created_at. Browse the returned list to find the
experiment matching the user's reference:
- By name: scan the
name field for matches
- By recency: results are ordered newest first by default
- By status: match the
status field (draft, running, stopped)
- By flag key: match the
feature_flag_key field
After finding matches
- Exactly one match: Use it. Confirm with the user by name before destructive actions (delete, ship, end).
- Multiple matches: List them with name, status, and creation date. Ask the user to pick.
- No matches: Tell the user. Suggest checking archived experiments or different terms.
Get full details if needed
After resolving to an ID, call experiment-get for the full object (metrics, flag details, parameters).
Examples
User: "pause my signup experiment"
Agent:
1. Calls experiment-list
2. Scans results, finds "New signup process" (ID: 1371, status: running)
3. Proceeds to pause experiment 1371
When NOT to search
- You already have the experiment ID from earlier in the conversation
- The user just created the experiment — you have the ID from the create response
- The user provided the ID directly
