PostHog Query Skill

Run HogQL (ClickHouse-compatible SQL) queries against PostHog via the CLI.

One-Time Setup

posthog-cli login  # authenticate interactively; stores token in ~/.posthog/credentials.json

Requires API key scope: query:read.

Command

posthog-cli exp query run "<SQL>"

Results are printed as JSON lines to stdout. The CLI reads auth from ~/.posthog/credentials.json (set up via posthog-cli login).

Property Access Syntax

Use bracket notation for event properties — dot notation with quoted keys does not work:

-- ✅ Correct
properties['$current_url']
properties['$browser']

-- ❌ Wrong
properties.'$current_url'

Examples

Count all pageviews:

posthog-cli exp query run "SELECT count() as pageviews FROM events WHERE event = '\$pageview'"

Filter by URL:

posthog-cli exp query run "SELECT count() as pageviews FROM events WHERE event = '\$pageview' AND properties['\$current_url'] LIKE 'https://example.com/%'"

7-day daily trend:

posthog-cli exp query run "SELECT toDate(timestamp) as date, count() as pageviews FROM events WHERE event = '\$pageview' AND timestamp >= now() - INTERVAL 7 DAY GROUP BY date ORDER BY date"

Recent events:

posthog-cli exp query run "SELECT event, timestamp FROM events ORDER BY timestamp DESC LIMIT 10"

Other Subcommands

• posthog-cli exp query editor — interactive query editor
• posthog-cli exp query check "<SQL>" — syntax/type check without running
• Append --debug to run to get the full JSON response (columns, types, cache info)

Notes

• HogQL is ClickHouse-compatible SQL — standard ClickHouse functions apply
• Shell-escape $ in event names: '\$pageview' or use double quotes carefully
• The --debug flag returns full metadata including column types and cache status
