Validate a Feature Direction Before Building
You have a feature idea but aren't sure if the approach is sound. You want industry best practices and deep research to sharpen the direction before writing any code.
Skill
Role
/best-practices
Audit against industry standards and patterns
/deep-research
Multi-source research (web + codebase + docs)
/feasibility-study
Quantitative comparison of approaches
/codex-brainstorm
Adversarial debate to stress-test the plan
/deep-research <topic> — gather state-of-the-art approaches, prior art, and ecosystem conventions
/best-practices — audit the proposed approach against industry patterns; identifies gaps and anti-patterns
Synthesize: combine research findings with best-practice gaps into 2-3 candidate approaches
/feasibility-study — quantitative trade-off analysis across candidates
/codex-brainstorm — adversarial debate on the top candidate; finds blind spots
Decision: proceed with refined approach, or pivot based on findings
Solo skill
Limitation
Combined effect
/deep-research alone
Broad information, no opinionated filter
/best-practices filters research through proven patterns
/best-practices alone
Checks against standards but doesn't explore alternatives
/deep-research provides the landscape of alternatives
/feasibility-study alone
Compares options but may miss industry context
Research + practices provide well-informed candidates
Situation
Choice
Research reveals the idea already exists?
Evaluate existing solutions; adapt rather than reinvent
Best practices audit finds anti-patterns?
Redesign before investing in feasibility study
Brainstorm debate reaches no consensus?
Prototype both approaches; use evidence to decide
Direction is validated?
Proceed to /tech-spec → /feature-dev
No enforced gates — this is an exploration workflow. The output is a validated direction with supporting evidence.
Clear understanding of the problem landscape (research)
Approach validated against industry best practices
Quantitative comparison of alternatives
Blind spots identified via adversarial debate
Confident direction ready for /tech-spec
