Prompt
Our backend team is using specification-driven development, but we frequently hit mismatches between our feature spec docs and the AI-generated code output. Please design an iterative development and review cycle that establishes traceability between feature requirements and generated code, including a systematic approach to refine prompts when output drifts from specs.

Spec-Kit Claude Code Workflow Skill
When to Use This Skill
Use this conceptual skill when you need to establish and follow an effective development workflow combining Spec-Kit specifications with Claude Code assistance. This skill is appropriate for:
Starting new projects with clear specification-driven development
Organizing multi-folder repositories with consistent workflows
Guiding team members through Spec-Kit + Claude Code processes
Establishing best practices for specification-driven development
Iterating on specifications and implementations simultaneously
Maintaining consistency across different development phases
This skill should NOT be used for:
Projects without established specifications
Ad-hoc development without structured processes
Teams that prefer code-first approaches without specifications
Rapid prototyping where specifications would slow development
Prerequisites
Understanding of Spec-Kit specification concepts
Access to Claude Code for AI-assisted development
Repository with established folder structure
Clear understanding of project requirements and goals
Commitment to specification-driven development approach
Query the Sequence Read Archive (SRA), retrieve scientific publications, and analyze
genomics metadata using the SRAgent toolkit. Supports accession conversion (GSE→SRX→SRR),
BigQuery metadata queries, manuscript downloads from multiple sources, and scRNA-seq
technology identification. Use when working with SRA/GEO datasets, finding publications,
or analyzing single-cell sequencing experiments.
