Best practices for agents managing PostHog skills via the MCP `skill-*` tools : how to discover.

What this skill does for you

Best practices for agents managing PostHog skills via the MCP `skill-*` tools : how to discover, read, create, update, and refactor skills efficiently, especially large skills with many bundled files. Use whenever you are about to call any `skill-*` tool, asked to author or edit a shared skill, or troubleshoot why a skill write was rejected. Pairs with `skills-store` (which covers the raw tool surface) by adding the decision-tree, efficiency, and pitfall guidance.
