Agent Skills

Instruction packs that give your AI agent know-how — some work anywhere, some only with the tool they came with.

✦ Standalone skills3,224

Self-contained. Install one into any project and it works on its own — no other software needed.

🧰 Tool add-ons530

Come bundled with a specific tool and only work together with it — they teach your agent how to operate that tool.

🔌 Needs setup first123

Each relies on something you set up separately — such as an app, a command-line tool or an account — and its page names what that is.

managing-experiment-lifecycle

by posthog

Guides experiment state transitions: launching, pausing, resuming, freezing/unfreezing exposure, ending, shipping variants, archiving, resetting, duplicating, and copying to another project. Covers preconditions, implications for variant assignment and analysis, and the decision framework for when to use each action. TRIGGER when: user asks to launch, pause, resume, end, ship, archive, reset, duplicate, or copy an experiment to another project, or to freeze/unfreeze exposure (stop enrolling new users while metrics keep flowing, or reopen enrollment). DO NOT TRIGGER when: user is creating an experiment (use creating-experiments), configuring rollout (use configuring-experiment-rollout), or setting up metrics (use configuring-experiment-analytics).

exploring-autocapture-events

Guides exploration of $autocapture events captured by posthog-js to understand user interactions, find CSS selectors (especially data-attr attributes), evaluate selector uniqueness, query matching clicks ad-hoc, and create actions. Use when the user asks about autocapture data, wants to find what users are clicking, needs to build actions from click events, asks about elements_chain, wants to build a trend or funnel filtered by clicks or other autocapture interactions, asks which properties autocapture sends, or asks how to filter $autocapture events. Only applies to projects using posthog-js autocapture.
