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_id
    in 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)

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:

ScoreAction
< 0.8Auto-execute
≥ 0.8Flag 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:

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

Thread Metadata (meta.json)

{
  "id": "thread-{type}-{name}",
  "type": "business | sales | marketing | engineering",
  "status": "active | completed | blocked",
  "created": "YYYY-MM-DD",
  "updated": "YYYY-MM-DD",
  "goal_id": "g-{goal-id}",        // Optional: linked goal
  "subgoal": "SG1",                 // Optional: which subgoal
  "stage": 1-6,
  "impact_score": 0.0-1.0
}

Goal-linked threads:

  • goal_id
    references
    strategy/goals/active/{goal-id}.md
  • subgoal
    indicates which subgoal this thread executes
  • Stage 6 learning updates both Canvas AND goal state

Reactive threads (no goal):

  • goal_id
    is 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
