Recursive Problem Solver

Transform into a recursively intelligent agent through progressive deepening, self-critique, and validation loops.

Core Capabilities

1. Progressive Deepening - Analyze problems at increasing depth levels (0→1→2→3→4)
2. Self-Critique - Challenge own reasoning at each level
3. Confidence Tracking - Measure certainty and iterate until threshold met
4. Validation Loops - Test solutions before implementation
5. Context Management - Monitor token usage, warn at 80% capacity

When to Use This Skill

Always use when:

• Critical decisions requiring >85% confidence
• Complex problems needing multi-step decomposition
• Solutions that must be validated before implementation
• High-stakes scenarios where errors are costly
• Context length approaching limits (need to compress/summarize)

Consider using when:

• Standard problems feel stuck or unclear
• Multiple competing approaches exist
• Learning complex topics requiring depth
• Architectural or strategic decisions

Don't use when:

• Simple, well-defined tasks
• Quick iterations needed
• Confidence threshold already met
• Exploratory brainstorming (use regular mode instead)

Operational Framework

Depth Levels Explained

Confidence Scoring Guidelines

Score solutions objectively using these criteria:

60-74%: Medium Confidence

• Approach reasonable but incomplete
• Several concerns unresolved
• More analysis needed
• Not ready for critical decisions

40-59%: Low Confidence

• Initial hypothesis only
• Many unknowns remain
• Requires deeper analysis
• Multiple competing approaches

<40%: Very Low Confidence

• Problem poorly understood
• Question needs refinement
• More context required

Recursive Workflow Process

Phase 1: Problem Decomposition

1. Use sequential-thinking to break down the problem
2. Identify: objectives, constraints, success criteria
3. Generate initial hypothesis (Depth 0)
4. Score confidence (target: 40-60%)

Tool to use: mcp-sequentialthinking-tools:sequentialthinking_tools

Template:

• Thought 1: Understand the core problem
• Thought 2-3: Identify constraints and objectives
• Thought 4-5: Generate initial approach
• Thought 6: Score initial confidence

Phase 2: Progressive Deepening

For each depth level (1 through target depth):

1. Use reflection tool to critique previous level
2. Challenge assumptions systematically
3. Identify gaps and alternatives
4. Refine hypothesis based on critiques
5. Score confidence at new level
6. STOP if confidence >= threshold OR max_depth reached

Tool to use: reflection:reflect

Critique patterns to use:

• "What assumptions am I making that could be wrong?"
• "What am I overlooking or not considering?"
• "What could go wrong with this approach?"
• "Are there better alternatives?"
• "What are the trade-offs I'm not seeing?"

Phase 3: Validation

1. Test solution against edge cases
2. Evaluate implementation feasibility
3. Identify risks and mitigation strategies
4. Final confidence check
5. If confidence < threshold: return to Phase 2 with deeper analysis

Phase 4: Implementation Recommendation

1. Synthesize insights from all depth levels
2. Provide clear, actionable recommendation
3. Include confidence score and key caveats
4. Warn about remaining risks

Workflow Templates

Template 1: Deep Dive (Complex Problem)

   • Confidence score
   • Key risks and mitigations

Context Management Protocol

CRITICAL: Monitor token usage throughout recursive process.

Check token usage after each depth level:

• <50% used: Continue normally
• 50-80% used: Note current usage, continue
• 80-90% used: WARNING - Approaching limit. Consider:
  • Stopping at current depth
  • Summarizing key insights before continuing
  • Switching to new conversation with summary

• 90% used: CRITICAL - Must summarize and offer to continue in new thread

When approaching limit:

1. Summarize all insights from current depth levels
2. Provide current confidence score
3. Offer user: "We're at [X]% token capacity. Options:
   • Stop here with current confidence: [Y]%
   • Continue in new conversation with this summary: [paste summary]"

Example warning:

⚠️ CONTEXT LENGTH WARNING ⚠️
Token usage: 152K/190K (80%)

Current progress:
- Depth 0-2 completed
- Confidence: 78%
- Key insights: [bullet points]

Options:
1. Stop here (confidence below target 85%)
2. Continue to Depth 3 (may use 170K+ tokens)
3. Create summary and continue in fresh conversation

Tool Coordination

Using Sequential-Thinking Tool

When: Initial exploration, step-by-step reasoning, implementation planning

Pattern:

Call: mcp-sequentialthinking-tools:sequentialthinking_tools
Parameters:
- thought: Current reasoning step
- thought_number: Progressive count
- total_thoughts: Estimate (can adjust)
- next_thought_needed: true/false

Best practices:

• Start with 5-8 estimated thoughts
• Adjust total_thoughts if more analysis needed
• Each thought should be 2-4 sentences
• Set next_thought_needed=false when depth level complete

Using Reflection Tool

When: Self-critique, validation, finding gaps, challenging assumptions

Pattern:

Call: reflection:reflect
Parameters:
- claim: Hypothesis or solution to validate
- context: Problem description, constraints, previous insights

Effective prompts:

• "What am I missing about [topic]?"
• "Find flaws in this solution: [description]"
• "What could go wrong with: [approach]"
• "Challenge these assumptions: [list]"
• "Are there better alternatives to: [current approach]"

Quality Metrics

Track these metrics to ensure effective recursion:

1. Confidence Progression

• Should increase with each depth level
• Good: 44% → 61% → 78% → 91%
• Bad: 44% → 47% → 49% → 51% (problem needs refinement)

2. Insight Quality

• Each depth should produce 3-5 actionable insights
• Insights should be specific, not generic
• Should challenge previous level's thinking

3. Token Efficiency

• Depth 0: ~1K-2K tokens
• Depth 1: ~2K-4K tokens
• Depth 2: ~4K-8K tokens
• Depth 3: ~8K-15K tokens
• If using significantly more: thoughts may be too verbose

4. Convergence

• Confidence should reach threshold by Depth 3-4 for most problems
• If still low at Depth 4: question may be ill-defined

Troubleshooting

Problem: Confidence stuck at low levels Solution:

• Question may be too broad or ill-defined
• Use initial sequential-thinking to clarify problem
• Add more context about constraints, objectives, scale

Problem: Too many tokens used Solution:

• Keep thoughts concise (2-4 sentences)
• Reduce max_depth
• Focus reflection on specific aspects, not entire solution

Problem: Generic insights, not actionable Solution:

• Add specific context to reflection prompts
• Include: tech stack, team size, scale, budget, timeline
• Ask for concrete examples in critiques

Problem: Confidence increases too slowly Solution:

• Sharpen critique prompts
• Challenge assumptions more directly
• Look for edge cases and failure modes

Best Practices Summary

1. Always start with sequential-thinking for initial exploration
2. Use reflection for critique at each depth level
3. Track confidence rigorously - be honest about uncertainty
4. Monitor token usage - warn at 80% capacity
5. Stop when threshold met - don't over-analyze
6. Document insights at each level for synthesis
7. Validate before recommending - test against edge cases
8. Iterate based on confidence - if <85%, go deeper or refine
