hypothesis-ranked-tournament

hypothesis-ranked-tournament is a skill for Claude Code, Codex from panjose/Co-Scientist. It costs 18 tokens per session (419 once invoked), scanned A, original, Apache-2.0.

A comparison step for choosing between two leading research explanations, called hypotheses. It judges them on originality, reasoning, evidence, practicality, and likely value.

In plain words
What is it for?
Use it in a research process when two well-reviewed hypotheses need to be compared and one must be ranked higher.
Why use it?
It turns a close comparison into one ranked result instead of leaving the order undecided.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hypothesis-ranked-tournament scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

hypothesis-ranked-tournament

Goal:

  • Judge one ranked-tournament matchup between two top frontier hypotheses.

Inputs:

  • research_plan/RESEARCH_PLAN.json
  • two hypotheses/<id>/HYPOTHESIS.json artifacts with completed review bundles

Outputs:

  • one TournamentMatchContract result for a ranked tournament

Context Loading:

  • Open skills/shared-references/schema-index.md.
  • Read packages/agent_contracts/ranking.py and confirm the exact TournamentMatchContract shape before emitting the ranked result.
  • Read research_plan/RESEARCH_PLAN.json.
  • Read both hypotheses and their review bundles.
  • Confirm that the match strategy is ranked_tournament.

Execution Prompt Contract:

  • System Intent:
    • You are running a deeper comparative judgment for two high-ranked hypotheses whose relative ordering matters.
  • Required Reasoning Focus:
    • Compare novelty, mechanism quality, evidential grounding, feasibility, and expected downstream value.
    • When a debate-style internal comparison helps, keep it short and converge to one winner.
  • Do Not Do:
    • Do not leave the match undecided.
    • Do not ignore review weaknesses that materially change the ordering.
  • Output Shape:
    • Emit one TournamentMatchContract.
    • match_strategy: ranked_tournament
    • winner_id: one of the two hypothesis IDs
    • reasoning: concise but specific
    • debate_turns: optional short internal debate transcript when useful

Execution Steps:

  1. Open skills/shared-references/schema-index.md, then read packages/agent_contracts/ranking.py before emitting the ranked match artifact.
  2. Compare the two frontier hypotheses for ranked ordering.
  3. Choose exactly one winner.
  4. Emit one valid ranked-tournament match result.

Completion Rule:

  • This skill is complete only when one valid ranked match result has been produced with a non-empty winner and reasoning.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
