hypothesis-batch

hypothesis-batch is a skill for Claude Code, Codex from zjunlp/Mechanist. It costs 16 tokens per session (10,616 once invoked), scanned A, original, MIT.

An automated workflow that creates many research hypotheses, checks them, reviews them, and selects a smaller set for further development. It combines literature research, idea generation, novelty checks, impact checks, and method refinement.

In plain words
What is it for?
Generating batches of research ideas, ranking them, testing whether they are new and worthwhile, and preparing the strongest ones for detailed planning.
Why use it?
It reduces the manual effort needed to compare a large group of ideas and remove weak or flawed candidates.

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-batch 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 4d 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.

Workflow: Claim Stage — Behavior Discovery × Mechanism Discovery

Orchestrate the claim stage for: $ARGUMENTS.

Overview

This skill chains sub-skills into a single automated, non-interactive pipeline:

/research-lit → /idea-creator → /novelty-check → /impact-check → /research-review → /research-refine-pipeline
  (survey)      (brainstorm)    (verify novel)   (verify it     (critical feedback)  (refine method + plan)
                                                  matters)

Batch shape: 30 in, 10 out. Phase 2 brainstorms ~30 candidate ideas across three angle-partitioned /idea-creator rounds. Novelty (Phase 3) is a hard gate; impact (Phase 3.5) and external review (Phase 4) then score every survivor, and Phase 4.25 makes the single cut to 10 — vetoing fatal design flaws outright, then ranking by impact first, reviewer score second, novelty last. From Phase 4.5 on, each of the 10 is worked independently and in parallel, and each gets its own directory.

Deliverables.

idea-stage/
  RESEARCH_LIT.md          # raw retrieval dump (audit-only)
  LANDSCAPE.md             # synthesized landscape
  IDEA_REPORT.md           # all ~30 ideas, ranked, with eliminations — the batch index
claims/
  01_<name>/               # one directory per surviving idea, rank-ordered
    FINAL_PROPOSAL.md
    EXPERIMENT_PLAN.md
    claim.json             # ⭐ the deliverable a human reviewer reads
  02_<name>/
    …
  10_<name>/

claim.json is the point of the whole run: a self-contained paper skeleton written for a human expert reviewer, who sees that file and nothing else. Everything above it is working material. Its specification is Phase 4.8 and is binding.

Pipeline

Phase 1: Literature Survey

Invoke /research-lit to map the research landscape:

/research-lit "$ARGUMENTS"

What this does:

  • Search Zotero, Obsidian, local PDFs, the web, and the cloud mechanic-db SEARCH service (via the skill /mechanic-db-search) for relevant papers
  • Build a landscape map: sub-directions, approaches, open problems
  • Identify structural gaps and recurring limitations
  • Output two files: idea-stage/RESEARCH_LIT.md (raw retrieval dump, audit-only) and idea-stage/LANDSCAPE.md (synthesized landscape — Phase 2 reads this from disk)

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.

hypothesis-batch is a skill published in the GitHub repository zjunlp/Mechanist (51 stars, last pushed 8d ago), licensed MIT. It adds 16 tokens to every session and 10,616 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
