Claude Code Hooks: Build Automated Dev Workflows

This tutorial now teaches a zero-hook-default migration. You do not need Hooks to unlock Claude Code, use Skills, run agents, or hand work to another CLI. Start with the full native runtime and add automation only after a real repeated need appears.

Step 1: establish a zero-hook baseline

Start a fresh project session with no toolkit hooks enabled. Confirm that normal file editing, shell commands, tests, and stopping all work as expected under the permission profile you selected.

This baseline matters: without it, an old user-level registration can be mistaken for built-in CLI behavior.

Step 2: move intent into guidance

Put stable project context in CLAUDE.md: architecture, important commands, review expectations, and what “done” means. Write concise guidance that helps the model choose well instead of encoding a rigid script.

Examples of guidance:

• Prefer the smallest relevant test before the full suite.
• Summarize changed behavior and remaining uncertainty.
• Ask before publishing or changing external state.

Guidance remains visible, editable, and adaptable to the task.

Step 3: turn reusable procedures into Skills

Use a Skill when a procedure has several steps or supporting resources. A Skill can be selected when relevant and can explain trade-offs that a deterministic event handler cannot.

Good candidates include release preparation, issue investigation, session handoff, documentation review, and project health checks.

Step 4: keep validation at visible boundaries

Tests, linting, type checks, and builds are easiest to understand when they run as normal commands or CI jobs. The user sees when they start, what failed, and how to retry them.

Do not hide every validation command behind a lifecycle event. Automatic checks that run after every tool call can multiply latency and interrupt exploratory work.

Step 5: opt into one narrow hook only if needed

A hook is justified when all of these are true:

• a supported lifecycle event is the correct trigger;
• the action is deterministic and fast;
• project users know it is enabled;
• failure is recoverable;
• removing it does not break the toolkit;
• it does not force the agent to continue or silently deny broad classes of work.

Enable one project hook, observe it in real sessions, and keep it only if the benefit exceeds the interruption.

Step 6: audit inherited configuration

Review organization-managed, user, project, and local settings. Another CLI or extension may also load compatible Claude assets, so inspect what is effectively active rather than assuming an empty folder means zero hooks.

For each registration, ask:

• Who enabled it?
• Which event triggers it?
• What data can it read or transmit?
• Can it change, deny, or repeat an action?
• What is its timeout and removal path?

Remove duplicates, missing scripts, abandoned experiments, and automation whose owner or purpose is unclear.

Migration checklist

• The toolkit works with zero hooks.
• Guidance lives in CLAUDE.md.
• Reusable workflows live in Skills.
• Tests and delivery gates are visible commands or CI.
• Optional hooks are project-scoped and documented.
• Normal completion is never trapped by an automatic loop.
• Existing global and managed configuration has been audited.

For current hook events and configuration details, use Session 15: Hooks System. To install portable skills and agents with zero Director Mode hooks by default, use Director Mode Lite.
