Is the Segment Analysis skill free?

Yes. The skill itself is free from coalesce-labs/catalyst. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Segment Analysis SkillProof Score?

7.6/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 4/5.

How do I install Segment Analysis?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Segment Analysis with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Segment Analysis

PostHog-backed cohort/segment retention and comparison analysis — needs the plugin's PostHog MCP wired up separately.

Verdict: Works with setup

Environment: Claude Code 2.x (agent harness)

allowed-tools is just Task + TodoWrite — the skill has no query logic of its own; the real work needs the PostHog MCP server declared in the plugin's .claude-plugin/.mcp.json (with a POSTHOG_AUTH_HEADER token) which a verbatim skill-folder copy leaves behind, so it's inert until someone wires up PostHog access by hand.

What Segment Analysis does

Routes segment, cohort-retention, and comparison analysis requests (free vs paid, churned users, monthly cohorts) through PostHog data, delegating the actual query work via the Task tool. Triggers on customer segmentation, cohort retention, user-group comparison, churn, or funnel-by-segment questions, but only produces real numbers once the sibling plugin's PostHog MCP server and auth token are configured.

How to install Segment Analysis
