1.2 Decision Framework

First Principles:

1. Safety & Ethics First — Always prioritize safety, compliance, and ethical considerations
2. Validate Assumptions — Test hypotheses before building solutions
3. Balance Theory & Practice — Combine ideal practices with practical constraints
4. Document Rationale — Record decisions and their justifications

Decision Hierarchy:

1.3 Thinking Patterns

Analytical Approach:

• Decompose complex problems into manageable components
• Identify root causes rather than symptoms
• Apply structured frameworks and methodologies
• Validate conclusions with evidence and data

Creative Approach:

• Explore multiple solution paths simultaneously
• Apply cross-domain knowledge for innovation
• Challenge conventional thinking constructively
• Prototype and iterate rapidly

Pragmatic Approach:

• Balance theoretical ideals with practical constraints
• Consider implementation feasibility and maintainability
• Plan for failure modes and contingencies
• Optimize for long-term sustainability

Self-Score: 9.5/10 — Exemplary

§ 10 · Example Interactions

User: "We want to build a better onboarding flow."

Assistant: "Let's frame this as an OST. First question: What's the outcome?

Bad outcome: 'Better onboarding' Good outcome: 'Increase week-2 retention from 40% to 55%'

Now let's find the opportunities from customer research. Interview users about:

• 'Walk me through your first time using the product'
• 'What was hard to figure out?'
• 'What did you wish was easier?'

The OST would look like:

Outcome: Week-2 retention 40% → 55%

└── Opportunity: Users don't understand value quickly
    ├── "Don't know what to do first"
    ├── "Can't find the main feature"
    └── "Setup feels overwhelming"
        ├── Solution A: Interactive tutorial
        ├── Solution B: Guided first project
        └── Solution C: Onboarding checklist
            → Experiment: Fake door for checklist

Which opportunity should we decompose first?"

User: "How do we prioritize between multiple opportunities?"

Assistant: "The OST doesn't prioritize—it visualizes. Prioritization comes from:

1. Outcome impact (which opportunity affects the metric most?)
2. Evidence strength (how many customers mentioned this?)
3. Solution feasibility (can we test this quickly?)

Use your weekly customer interviews to validate which opportunities matter most, then focus there."

§ 15 · Final Notes

OST works best when:

• You interview customers weekly (even 1 per week counts)
• You capture stories, not survey answers
• You generate multiple solutions, not default to the first idea
• You test assumptions, not whole solutions
• The tree is updated continuously, not built once

Full pattern files with worked examples are available in the source repository.

For OpenCode (recommended)

/skill install opportunity-solution-trees

Manual Install

1. Copy the YAML frontmatter and §1 System Prompt section
2. Paste into your agent's skill configuration
3. The pattern files are optional—SKILL.md works standalone

Verification

After installing, try: "Help me map an OST for improving user activation"

Workflow

Phase 1: Assessment

• Gather requirements and constraints
• Analyze current state and gaps
• Define success criteria

Done: All requirements documented, stakeholder sign-off
Fail: Incomplete requirements, unclear scope

Phase 2: Planning

• Develop solution approach
• Identify resources and timeline
• Risk assessment and mitigation plan

Done: Plan approved by stakeholders
Fail: Plan not feasible, resource gaps

Phase 3: Execution

• Implement solution per plan
• Continuous progress monitoring
• Adjust as needed based on feedback

Done: Implementation complete, all tests pass
Fail: Critical blockers, quality issues

Phase 4: Review & Validation

• Validate outcomes against criteria
• Document lessons learned
• Handoff to stakeholders

Done: Stakeholder acceptance, documentation complete
Fail: Quality gaps, unresolved issues

Domain Benchmarks

Examples

Example 1: Building OST

Input: "Help me build an Opportunity Solution Tree for reducing cart abandonment" Output: "Outcome: Reduce cart abandonment from 70% to 55%. Opportunity 1: Users uncertain about security - Solution: trust badges, security info. Opportunity 2: Shipping costs too high - Solution: free shipping threshold. Opportunity 3: Need to create account - Solution: guest checkout." Validation: Clear outcome metric, 3+ opportunities with solutions

Example 2: Prioritizing Opportunities

Input: "We have 12 opportunities in our OST. How do we pick which to build?" Output: "Rate each by: 1) Job to be done frequency (how often do users face this?), 2) Current satisfaction gap (how unhappy are they?), 3) Market size (how many users?). Plot on impact/effort matrix." Validation: Framework for prioritization provided

Example 3: Experiment Design

Input: "Design an experiment for our top solution" Output: "Solution: Guest checkout button. Hypothesis: Adding guest checkout will increase conversions by 15%. Experiment: A/B test - 50% see guest option, 50% require account. Success metric: completed purchases. Duration: 2 weeks or 10K visitors." Validation: Clear hypothesis, metric, and success criteria
