Examples
Questions teams actually ask.
The tools it pulls from are shown inline — every answer in Lumen cites the underlying records it read.
Pull results for our checkout-button experiment — is the variant winning, and is it significant?
Which feature flags are still rolled out to less than 100% of users? List them with rollout percentage.
Scope
What Lumen sees. What it can change.
Read is on by default. Every write is a separate toggle, capped per user, and logged.
What Lumen reads
Lumen calls PostHog's REST API using the personal API key you paste at install, scoped to the projects you authorise.
- Events & queries
Run HogQL or insight-style queries against your event stream
- Insights & dashboards
Definitions and current values for any saved insight or dashboard
- Funnels & retention
Multi-step funnel definitions, drop-off counts, retention cohorts
- Experiments
Setup, variant assignment, conversion deltas, statistical significance
- Feature flags
Definition, rollout percentage, conditions, variant keys
What Lumen can write
Lumen does not write to PostHog by default. Feature-flag toggles can be admin-enabled per project if you want the agent to act.
Every call is logged with user, operation, project, query (when used), and date range. Exportable as CSV.
