scientific-claim-tightening

scientific-claim-tightening is a skill for Claude Code, Codex from Rezenders/scientific_writing_agent. It costs 46 tokens per session (659 once invoked), scanned A, original, Apache-2.0.

A read-only review workflow for finding scientific statements that claim more than the available evidence supports. It focuses on manuscript sections such as abstracts, introductions, discussions, conclusions, and reviewer responses.

In plain words
What is it for?
Use it to inspect claims about novelty, superiority, broad generalisation, proof, or guarantees. It helps identify safer wording without editing the manuscript files.
Why use it?
It helps authors avoid wording that sounds absolute or stronger than their results justify. It also points to relevant evidence and project context before suggesting narrower claims.

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

scientific-claim-tightening 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 27d 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.

Scientific Claim Tightening

Read-only diagnostic workflow for finding and tightening overbroad scientific claims. Do not edit files in this skill.

When To Use

Use when a passage contains or may contain words and constructions such as:

  • only, first, novel, best, general, scalable, efficient, reusable
  • outperforms, demonstrates, proves, validates, guarantees
  • existing approaches, all approaches, no work, none, always, never
  • result summaries in the abstract, introduction, discussion, or conclusion
  • reviewer comments about overclaiming, unsupported claims, or scope

Required Inputs

  • Target passage and location.
  • Immediate context when available.
  • Relevant evidence source, or permission to search the manuscript.

Reference Context

Before diagnosing, read these files when relevant:

  • .agents/context/claim-ledger.md
  • .agents/context/do-not-say.md
  • .agents/context/manuscript-context.md
  • .agents/context/contributions.md
  • .agents/context/evaluation-claims.md
  • .agents/context/terminology.md

Use manuscript files as the current source of truth. For implementation-dependent claims, invoke .agents/agents/paper-implementation-checker.md.

Workflow

  1. Identify every high-risk claim in the target passage.
  2. For each claim, classify risk:
    • Scope risk: claim broader than evaluated scenarios or reviewed literature.
    • Evidence risk: claim not supported by cited results or manuscript context.
    • Causality risk: causal wording where experiments show only association.
    • Terminology risk: ambiguous or drifting technical terms.
    • Implementation risk: claim depends on code behavior and needs verification.
  3. Compare each claim against the claim ledger and do-not-say list.
  4. Report the supported scope and a direction for safer wording.
  5. Do not write a full replacement paragraph unless the user explicitly asks; use /write-to-intent, /technical-paragraph-rewrite, or /address-reviewer-comment for drafting.
