## What it does

This skill routes PostHog queries from Codex and ChatGPT to your analytics project. It covers event trends and HogQL queries. Instead of relying on static training data, the agent searches documentation tools for exact syntax.

Workflows enforce read operations before any writes. Destructive steps require explicit confirmation first. The agent will not toggle production flags blindly. Without an active PostHog OAuth connection and a selected project, the underlying tools will not respond.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill posthog -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/posthog/SKILL.md` — For all projects use ~/.agents/skills/

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill posthog -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/posthog/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/posthog/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/posthog/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins posthog
```

2. **Manually: put the files in place**
- File: `.github/skills/posthog/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/posthog/skills/posthog
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/posthog/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/posthog/skills/posthog/SKILL.md

## When to use it
- run HogQL queries over events and user properties
- toggle or audit feature flags across environments
- inspect conversion funnels and experiment readouts
- investigate application errors and exception issues

## Example prompts
- Run a HogQL query showing weekly active users for the current quarter in PostHog.
- Check the rollout conditions for the feature flag `beta-dashboard`.
- Show the error issues spike from yesterday and link them to recent sessions.

# PostHog

## Overview

This skill provides a structured workflow for working with PostHog from ChatGPT and Codex. It assumes the bundled PostHog app is connected so the PostHog tools are available for analytics, feature flags, experiments, error tracking, and more.

PostHog is an all-in-one product platform. The same project's data backs every surface below, so most questions can be answered by querying analytics or running HogQL, and most product changes (flags, experiments, surveys) can be made directly.

**Prefer live tools over pre-trained knowledge.** Your baked-in knowledge of PostHog's API, HogQL functions, and tool shapes may be outdated. The connected PostHog app advertises its own skills and tools at runtime and asks clients to *prioritize its skills over raw tools* — discover and follow those rather than guessing. When in doubt about syntax, limits, or product behavior, use the documentation-search tool.

## Prerequisites
- The PostHog app must be connected and accessible via OAuth.
- Confirm which PostHog organization and project the request targets before reading or writing.
- Self-hosted users connect against their own instance during the app's OAuth flow.

## Required Workflow

**Follow these steps in order. Do not skip steps.**

### Step 0: Connect the PostHog app (if not already configured)

If PostHog tools are unavailable, pause and ask the user to connect the PostHog app:

1. Enable the bundled PostHog app for this plugin or session.
2. Complete the PostHog OAuth flow if prompted, and select the correct organization/project.
3. Restart Codex or the current session if the tools still do not appear.

After the app is connected, finish your answer and tell the user to retry so they can continue with Step 1.

### Step 1
Clarify the user's goal and scope (e.g., a metric over a time range, a funnel, a new feature flag, an experiment readout, an error investigation). Confirm the target project, date range, event/property names, and any filters or cohorts.

### Step 2
Discover the available PostHog skills/tools the connected app exposes and pick the right one for the task. Resolve identifiers (project ID, flag key, experiment ID, insight/dashboard ID, error issue ID) before calling tools. For anything involving syntax, function names, or product behavior, search the docs first.

### Step 3
Execute PostHog tool calls in logical batches:
- **Read first** — list/get/query (insights, events, HogQL/SQL, error issues) to build context.
- **Write next** — create or update flags, experiments, surveys, dashboards, or insights with all required fields.
- For destructive or broad changes (e.g., toggling a flag in production, ending an experiment), state the impact and confirm before applying.

### Step 4
Summarize results with concrete numbers and links to the PostHog UI where available, call out caveats (sampling, person-on-events timing, date ranges), and propose next actions.

## Capability Map

Use this to route a request to the right PostHog surface, then discover the exact tool the app exposes for it.

| If the user wants to… | PostHog surface |
| --- | --- |
| Answer a metric/trend/funnel/retention/path question | Insights & queries (trends, funnels, retention, paths, lifecycle, stickiness) |
| Run arbitrary SQL over events/persons | HogQL / SQL execution |
| Create, toggle, or audit a feature flag | Feature flags |
| Launch or read out an A/B test | Experiments |
```
