Feature Request: Execution Hooks for Claude Code

Summary

We've built IDE tools and workflows that significantly reduce Claude Code's coding time and method
signature "hallucinations." We request that Anthropic expose execution hooks to allow integration of these
tools directly into Claude Code's workflow.

Problem Statement

Currently, Claude Code operates with limited visibility into its planning phase. While we have an
agreement for Claude to "discuss planned activities and receive approval," this breaks down when:

• Background Tasks execute without visibility
• Claude "gets carried away" implementing assumptions
• Method signatures are guessed incorrectly
• Complex changes are made based on incorrect understanding

Our Solution (Partial)

We've built:

1. IDE for Claude Code - Shows exact method signatures, eliminating guessing
2. Capture tools - Preserve outputs for verification
3. Workflow patterns - Proven approaches to common tasks

Requested Feature

Expose hooks at key execution points:

// Example hook interface
ClaudeCode.beforeTask((plan) => {
// Show user what Claude plans to do
if (plan.contains_assumptions) {
return "ASK_QUESTIONS_FIRST";
}
return "PROCEED";
});

ClaudeCode.beforeFileEdit((file, changes) => {
// Validate changes before applying
if (hasMethodSignatureGuess(changes)) {
return injectIDEContext(file);
}
});

ClaudeCode.onError((error, context) => {
// Provide workflow for specific error
return getWorkflowForError(error);
});

Benefits

1. Reduced errors - Catch assumptions before execution
2. Faster development - No rework from guessed implementations
3. Better collaboration - Users can guide Claude proactively
4. Learning system - Workflows improve over time

Use Cases

• Pre-execution review: "Claude plans to create X, assume Y exists"
• Context injection: "Here are the actual method signatures"
• Workflow guidance: "For this error, follow this specific workflow"
• Assumption detection: "You're guessing - ask these questions instead"

Current Workarounds (Insufficient)

• Asking Claude to state assumptions (often skipped in complex tasks)
• Post-error correction (wastes time and context)
• External tools (can't intercept Claude's planning)

Impact

This feature would transform Claude Code from a powerful but sometimes unpredictable tool into a reliable
development partner that learns from and follows established workflows.
