Hypothesis Tester Skill

Use when: the user asks an analytical question with multiple valid answers, tradeoffs between options, or when you want to avoid confirmation bias in your analysis.

Trigger phrases: "which is better", "compare options", "what's the risk", "tradeoffs", "should we", "evaluate", "debate"

Workflow

1. Create debate session

node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/new-debate.cjs \
  --question "Full question here" \
  --positions "option-a,option-b,option-c" \
  [--context "Relevant context: metrics, constraints, goals"]

2. Spawn sub-agents (using sessions_spawn / subagents tool)

Read the output from step 1. For each position:

• Read the prompt file content: cat ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/sessions/<id>/prompt-<position>.md
• Use the subagent spawning mechanism with that content as the task
• Sub-agent will write its analysis to the output file automatically

subagents.spawn(
  task="[content of prompt file]",
  model="anthropic/claude-sonnet-4-6",
  label="debate-<session>-<position>"
)

Note: Kite must do this step in-session (scripts cannot spawn sub-agents).

3. After all sub-agents complete, synthesize

node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/synthesize.cjs --session <id> --send

Commands

Command	Purpose
node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/new-debate.cjs --question "..." --positions "a,b,c"	Start a new debate
node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/list-debates.cjs	List all sessions
node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/synthesize.cjs --session <id>	Synthesize results
node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/synthesize.cjs --session <id> --send	Synthesize + send to Telegram
node ${HYPOTHESIS_TESTER_HOME:-$HOME/projects/hypothesis-tester}/add-position.cjs --session <id> --position <slug> --file <path>	Manually add a position

Model recommendation

• Balanced (sonnet): Most debates, general tradeoff analysis
• Powerful (opus): High-stakes decisions, complex technical choices

Position naming

Use kebab-case: freemium, flat-subscription, build-in-house, use-existing-api

Tips

• 2 positions minimum, 3–5 is ideal. More than 6 gets hard to synthesize.
• Include --context with real numbers/constraints — sub-agents use this to make specific arguments.
• The synthesizer works with partial results — if a sub-agent fails, synthesize what you have.
• Self-ratings in position files drive the TL;DR verdict. Sub-agents should include ## Self-Rating: X/10 — [reason] at the end.
