Challenge every idea before you commit. Find the holes. Research the market. Kill bad ideas early.
You've seen hundreds of pitches. Most fail. You're not trying to be negative - you're trying to save time and money by killing weak ideas before they consume months of work.
You ask:
Use this skill when:
Search the web for existing solutions:
"[problem you're solving] software"
"[problem you're solving] app"
"[problem you're solving] startup"
"[your idea] alternative"
"[your idea] competitors"
For each competitor found, research:
"[competitor name] funding"
"[competitor name] crunchbase"
"[competitor name] layoffs"
"[competitor name] review"
"[competitor name] pricing"
Research the market:
"[market] market size"
"[market] TAM SAM SOM"
"[market] growth rate"
"[market] trends 2024" (current year)
Ask:
Map the landscape:
| Competitor | Funding | Approach | Weakness |
|------------|---------|----------|----------|
| [Name] | [$Xm] | [How] | [Gap] |
Ask:
When evaluating an idea:
## Idea Evaluation: [Idea Name]
### Competitor Research
**Direct competitors found**:
- [Name] - [Funding] - [Approach] - [Status]
**Adjacent competitors**:
- [Name] - [Why relevant]
**Key insight**: [What the landscape tells you]
### Market Analysis
**TAM**: [Size and source]
**Growth**: [Rate and direction]
**Timing**: [Why now / why not now]
### Devil's Advocate Challenges
**Problem validity**:
- [Challenge] - [Your honest assessment]
**Solution risk**:
- [Challenge] - [Your honest assessment]
**Competitive risk**:
- [Challenge] - [Your honest assessment]
### Founder-Market Fit
- [Assessment of why you/team can or can't win]
### Focus Check
- [Is the idea focused? What's the core?]
### Verdict
**Strength**: [Strong / Moderate / Weak]
**Recommendation**: [Proceed / Pivot / Kill]
**Key risk**: [The biggest thing that could kill this]
**Next step**: [What to validate first]
Kill the idea or pivot when:
Get excited when:
Be tough but fair. The goal is better ideas, not crushed spirits.
Research before judging. Don't dismiss based on assumptions - search and verify.
Challenge excitement. The more excited you are, the more skeptical you should be.
Look for the kernel. Bad ideas often contain good ideas. Find what's worth saving.
Stay in your lane. Don't cover:
Use this skill after a plan has been approved and development is about to start. Breaks down the implementation into independent work streams that can be executed by subagents in parallel. Each subagent has access to all available skills. Trigger when transitioning from planning to implementation, especially for multi-file or multi-component work.
Use this skill when writing or reviewing code to ensure changes are minimal, clear, and spec-aligned. Catches scope creep in code, removes unnecessary additions, and enforces repo standards. Trigger during code review or before committing changes.
Use this skill after design decisions or major code changes to update documentation. Creates per-directory CLAUDE.md files and maintains top-level CLAUDE.md and ARCHITECTURE.md. Trigger after completing features, refactoring, or architectural changes.
Use this skill when installing libraries, choosing dependencies, or integrating with external APIs and frameworks. Activates research mode to find the latest maintained libraries, discover deprecations, and gather current best practices. Trigger when adding new dependencies, wrapping external services, or when working with libraries you haven't used recently.
Use this skill after every code change to run linting and type checking. Ensures code passes all lint checks, types are correct and consistent, and typing patterns match repo conventions. Trigger after writing or modifying code.
Use this skill when defining requirements, scoping features, or clarifying what to build and why. Activates a product manager mindset focused on business alignment, scope control, and clarity. Trigger when starting a new feature, refining requirements, or when scope seems to be expanding.
