SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the problem of unreliable or poorly defined GitHub issues by delegating the validation process to a specialized Fable 5 subagent, ensuring that every issue is technically feasible and well-scoped before work begins.

Core Features & Use Cases

  • Automated Fact-Checking: Traces claims against the actual codebase to verify accuracy and consistency.
  • Complexity Scoring: Automatically assigns a complexity score (C0–C100) and determines if a Fable plan is required.
  • Safe Execution: Operates in a read-only mode to prevent accidental file edits or repository changes during the validation phase.

Quick Start

Trigger the validation process for a specific issue by typing /fable-validate followed by the issue number in your chat session.

FAQPage Schema
How do I validate GitHub issues against my codebase automatically?

Validating GitHub issues automatically involves delegating claim tracing and architectural consistency checks to a Fable 5 subagent. It verifies code references and complexity scores in read-only mode without modifying the file system.

What does automated issue fact-checking do to verify code references?

Automated issue fact-checking traces claims made in GitHub issues against the actual codebase to verify their accuracy and architectural consistency. This ensures every issue is technically feasible and well-scoped before work begins.

Can I use this GitHub issue validation tool without modifying my repository?

Yes, you can validate GitHub issues without modifying your repository. The skill operates in a read-only mode via a subagent harness, preventing accidental file edits or repository changes during the validation phase.

How do I trigger GitHub issue validation in my chat session?

To trigger GitHub issue validation, type the /fable-validate command followed by the specific issue number in your chat session. This initiates the validate-issue procedure and returns a structured verdict.

Does automated complexity scoring determine if a Fable plan is required?

Yes, automated complexity scoring assigns a score from C0 to C100 to GitHub issues and determines if a Fable plan is required. This helps evaluate the technical scope and feasibility before development starts.

What limitations exist when using a read-only subagent for issue tracking?

The main limitation of using a read-only subagent for issue tracking is that it cannot execute file edits or apply repository changes. It requires a read-only subagent harness strictly to return a structured verdict for main agent action.
