Creates and improves event-driven hooks (Advanced tier) for a plugin to the Advanced Skill Library Standard. Use when you need to add a hook, enforce a guard on a tool or session event, inject context, or document a hook's event, scope, and failure behavior.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# askit-build-hook ## Purpose Author a plugin's hooks: event-driven enforcement or context injection (Standard sec 3.5). Hooks are an Advanced-tier capability. Two modes: `create` scaffolds a hook and its registration; `improve` raises an existing hook toward the bar (documentation, idempotency, actionable block messages). The hook SKILL is portable; what it authors is primarily a Claude capability (31 events) with a smaller Codex event set. Authoring depth is in [references/authoring-hooks.md](references/authoring-hooks.md). Follows the shared builder contract ([../../docs/reference/builder-pattern.md](../../docs/reference/builder-pattern.md)). ## When to use When the user asks to add, scaffold, author, or improve a hook (a PreToolUse / PostToolUse / Stop / SessionStart guard, a context injector, or any event-driven automation) for a plugin. ## create mode 1. Brief interview: the event (for example PreToolUse), the trigger or matcher, the hook type (`command` / `http` / `mcp_tool` / `prompt` / `agent`), the scope (what it guards or injects), and the failure behavior (fail-safe block vs warn). Skip the interview if these are in context. …

How to install
mdr add product-on-purpose/agent-skills-toolkit/askit-build-hook@sha256:ac9223d1a2641331The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
