State of Claude Code Hooks 2026
A snapshot of the Claude Code hooks ecosystem, derived directly from the HeyClaude registry. Hooks run shell commands automatically on Claude Code events — this report covers which events they fire on, what they automate, how involved they are to set up, and how consistently they disclose what they do.
Data as of June 20, 2026 (UTC).
Hook event distribution
Which Claude Code lifecycle event each hook fires on, taken from the registry trigger field.
Most common hook use cases
The tasks hooks automate, from their registry tags (mechanism tags like “hooks” excluded). A hook can cover several use cases.
Implementation complexity
Setup/maintenance complexity from the registry difficulty score; unscored hooks are omitted.
Setup prerequisites
Whether a hook needs prerequisites (accounts, tools, or config) before it runs.

Methodology & citation
Figures are computed at build time from the 87 Claude Code hooks in the HeyClaude registry, snapshot dated June 20, 2026. The hook event is read from each entry's declared trigger; use cases come from registry tags (mechanism tags such as “hooks” are excluded); complexity uses the maintainer-assigned difficulty score. Safety and privacy disclosure is required during review, which is why coverage is near-total — the differentiator is that every hook says what it executes and what data it touches.
