ClearSpec: A Spec Generator to Reduce Hallucination in Claude Code
ClearSpec: Structured Spec Generation for Claude Code
ClearSpec is a specification generator designed to address the problem of Claude Code producing technically functional but incomplete implementations due to vague input descriptions. The tool converts plain English descriptions into detailed, structured specifications that serve as improved prompts for Claude Code.
How It Works
Users describe what they want in plain English, connect their GitHub repository, and ClearSpec generates a structured specification containing:
- User stories
- Acceptance criteria
- Failure states
- Verification criteria
All specifications reference real file paths and dependencies from the connected codebase. The generated specification then becomes the prompt for Claude Code, providing context the model can actually use.
Source Details
The tool was developed by a user who has been using Claude Code daily for a year and identified that the #1 problem isn't the model itself, but rather vague descriptions leading to implementations that miss half the edge cases.
ClearSpec is currently free during early access with limitations of 5 specs per month, no credit card required. The creator is seeking feedback from other Claude Code users.
