| description | Execute evidence-based decision-making through 6-stage causal flow. Use for known processes, operational execution, and decisions with clear cause-effect chains. |
Causal Reasoning
Execute systematic cause-effect reasoning. The logic of process and action.
Relationship to Goals
Threads are the execution layer for goals. Goals define what to achieve; threads define how.
Goal (goal-setter)
└── Subgoal
└── Thread (reasoning-causal) ← executes via 6-stage flow
└── Learning → updates Goal state (goal-tracker)
Thread types:
- Goal-linked: Created from subgoals, has
goal_idin metadata - Reactive: Created from signals (no goal), may spawn or link to goal
Type Signature
Causal : Input → Hypothesis → Implication → Decision → Action → Learning
Where:
Input : Observation × Context → FactualStatement
Hypothesis : FactualStatement × CanvasAssumption → TestableHypothesis
Implication : TestableHypothesis → (Impact × Probability × Timeline)
Decision : Implication × Alternatives → Commitment
Action : Commitment → [ExecutableTask]
Learning : [ExecutedTask] × Outcomes → CanvasUpdate × GoalUpdate
When to Use
- Process execution with known steps
- Decision with clear cause-effect chain
- Operational workflows (sales, marketing, engineering)
- Canvas hypothesis testing
- Action planning and execution
- Executing subgoals (goal-linked threads)

Thread-specific details: See references/threads/{type}.md
6-Stage Flow
Execute stages sequentially. Each stage produces a markdown file in the thread directory.
Stage 1: Input
File: 1-input.md
Purpose: Capture factual observation that triggers the flow.
Content:
- What happened? (fact, not opinion)
- When? Where? Who observed?
- Raw data/evidence links
- Context (what we believed before)
Rules:
- Facts only, no interpretation
- No solutions or recommendations
- Link to evidence
Detail: references/stages/input.md
Stage 2: Hypothesis
File: 2-hypothesis.md
Purpose: Link observation to Canvas assumption being tested.
Content:
- Which assumption does this challenge/validate?
- What do we believe will happen?
- What would prove us wrong?
- Testable prediction
Rules:
- Must reference
strategy/canvas/10-assumptions.md - State falsifiable hypothesis
- Define success/failure criteria
Detail: references/stages/hypothesis.md
Stage 3: Implication
File: 3-implication.md
Purpose: Analyze business impact with numbers.
Content:
- Revenue impact (quantified)
- Timeline (short/medium/long)
- Resource requirements
- Risk assessment
- Opportunity cost
Rules:
- Include specific numbers
- Compare scenarios
- Identify dependencies
Detail: references/stages/implication.md
Stage 4: Decision
File: 4-decision.md
Purpose: Make official commitment with impact score.
Content:
- Decision statement (PROCEED/DEFER/DECLINE)
- Alternatives considered
- Impact score calculation
- Approval status
Impact Scoring:
| Score | Action |
|---|---|
| < 0.8 | Auto-execute |
| ≥ 0.8 | Flag for human approval |
Mode-Aware Formulas:
VENTURE: Impact = (Strategic Value × Market Size × Defensibility) / 3
BOOTSTRAP: Impact = (Revenue Impact × Time to Cash × Margin) / 3
Check strategy/canvas/00-business-model-mode.md for mode.
Detail: references/stages/decision.md
Stage 5: Actions
File: 5-actions.md or 5-actions/ directory
Purpose: Generate executable tasks.
Content:
- Typed actions (sales:, marketing:, engineering:*)
- Assigned owners
- Deadlines
- Success criteria
- Dependencies
Action Types by Thread:
| Thread | Action Types | Skills |
|---|---|---|
| Sales | lead-intake, qualify, demo, pilot, close | sales-* |
| Marketing | research, create, publish, promote, measure | marketing-* |
| Engineering | requirements, specification, implementation | engineering-* |
| Business | varies by decision | - |
Detail: references/stages/actions.md
Stage 6: Learning
File: 6-learning.md
Purpose: Document outcomes and update Canvas + Goal.
Content:
- Actual vs expected outcome
- Hypothesis validated/invalidated?
- Canvas sections to update
- Goal metrics to update (if goal-linked)
- New threads generated
Rules:
- Update
strategy/canvas/10-assumptions.md - Link learning to original hypothesis
- If goal-linked: Update goal state via goal-tracker
- Generate follow-up threads if needed
Goal Integration:
If thread.goal_id exists:
1. Read goal from strategy/goals/active/{goal_id}.md
2. Update subgoal status (pending → completed)
3. Extract metrics from learning for goal state
4. Check if goal success criteria met
5. If all subgoals complete → mark goal completed
Detail: references/stages/learning.md
Workflow
Goal-Linked Thread (Primary)
1. Receive subgoal from goal-setter
2. Create thread: threads/{type}/{name}/
3. Set meta.json with goal_id and subgoal
4. Execute stages 1-6 sequentially
5. At Stage 4: Calculate impact, flag if ≥0.8
6. At Stage 6: Update Canvas AND goal state
7. Notify goal-tracker of completion
Reactive Thread (Fallback)
1. Receive signal (feedback, anomaly, opportunity)
2. Create thread: threads/{type}/{name}/
3. Set meta.json without goal_id
4. Execute stages 1-6 sequentially
5. At Stage 4: Calculate impact, flag if ≥0.8
6. At Stage 6: Update Canvas
7. Optionally: Link to existing goal or spawn new goal

Goal-linked threads:
goal_idreferencesstrategy/goals/active/{goal-id}.mdsubgoalindicates which subgoal this thread executes- Stage 6 learning updates both Canvas AND goal state
Reactive threads (no goal):
goal_idis null or absent- At completion, may link to existing goal or spawn new goal
Decision Authority
AI Autonomous (Impact <0.8):
- Within strategic direction
- ROI > 3x, risk low-medium
- Cost <$100K, timeline <3 months
Human Review (Impact ≥0.8):
- Strategic pivot
- ROI <2x, high risk
- Cost ≥$100K, timeline ≥3 months
- Canvas-altering decisions

Success Criteria
- Goal-aligned: Thread serves a goal subgoal (when goal-linked)
- Evidence-based: Starts with factual observation
- Hypothesis-driven: Links to Canvas assumptions
- Impact-analyzed: Quantified cost/benefit
- Traceable: Complete 6-stage audit trail
- Self-correcting: Canvas AND goal updates from learning
- Autonomous: AI executes >95% (impact <0.8)
Remember
Every decision flows through 6 stages. No shortcuts.
Goals are primary. Threads execute goals. Reactive threads are fallback.
This skill:
- Executes the 6-stage causal flow
- Links threads to goals (when goal-linked)
- Reads reference docs for detail
- Calculates impact scores
- Updates Canvas AND goal state from learning
- Flags high-impact items for human review
