Claude Scientific Writer is an AI-assisted research and writing tool that searches literature and produces documents such as scientific papers, reports, posters, grant proposals, and reviews with citations. Researchers and technical writers can use it as a Claude Code plugin, Python package, or command-line tool, with the catalogue entries defining agent workflows for it.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.02047 |
| Opus 5.5 | $0.00025 | $0.00819 |
| Sonnet 5.5 | $0.00013 | $0.00409 |
| Haiku 4.5 | $0.00006 | $0.00205 |
Grade A, and why
scientific-critical-thinking 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 28d 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 Critical Thinking
Overview
Critical thinking is a systematic process for evaluating scientific rigor. Assess methodology, experimental design, statistical validity, biases, confounding, and evidence quality using GRADE and Cochrane ROB frameworks. Apply this skill for critical analysis of scientific claims.
When to Use This Skill
This skill should be used when:
- Evaluating research methodology and experimental design
- Assessing statistical validity and evidence quality
- Identifying biases and confounding in studies
- Reviewing scientific claims and conclusions
- Conducting systematic reviews or meta-analyses
- Applying GRADE or Cochrane risk of bias assessments
- Providing critical analysis of research papers
Visual Aids (Optional)
Only add figures when the user explicitly requests a diagram (for example, a GRADE flowchart, bias decision tree, or evidence-quality framework).
When figures help:
- Critical thinking framework diagrams
- Bias identification decision trees
- Evidence quality assessment flowcharts
- GRADE or risk-of-bias evaluation frameworks
How to create figures:
- Preferred: Use the scientific-schematics skill for AI-generated diagrams from a natural-language description
- Alternative: Build figures in your usual tools (draw.io, PowerPoint, matplotlib, etc.)
Run from the repository root, with OPENROUTER_API_KEY set:
python skills/scientific-schematics/scripts/generate_schematic.py "GRADE evidence assessment flowchart with downgrade and upgrade factors" -o figures/grade_flowchart.png --doc-type report
Disclosure: AI schematic generation sends your prompt to OpenRouter (a third-party API). Do not include unpublished sensitive details unless that transmission is appropriate for your project.
Core Capabilities
Seven capability areas, each with the questions to ask and what the answers imply, are in references/core_capabilities.md:
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

scientific-critical-thinking is a skill published in the GitHub repository K-Dense-AI/claude-scientific-writer (2,530 stars, last pushed 7d ago), licensed MIT. It adds 63 tokens to every session and 2,047 once invoked, about $0.0003 per session on Opus 5.5. 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.

health-nutrition-expert
Apply cutting-edge 2025 nutrition science on longevity, metabolic health, gut microbiome, and evidence-based dietary patterns for optimal vitality and disease prevention. Use when planning a diet, evaluating a nutrition claim, or applying evidence-based guidance on longevity, metabolic, and gut health.
forge
Execute a defined research experiment with traceable inputs, configurations, runs, and outputs. Use for experiment implementation and reproducibility, not to invent the research claim.
ledger
Write a reproducible experimental plan for a chosen research question. Use after direction selection to define comparisons, data boundaries, metrics, and resource limits.
reckoning
Analyse research results against the recorded plan, inspect failure patterns, and bound the claims. Use for evidence review before writing or making a research decision.
crucible
Invent and reshape research mechanisms through analogy, inversion, and recombination. Use while the idea is unsettled; no mandatory tournament, novelty certificate, or convergence.
ai-analyzer
An AI health-analysis system that combines health, lifestyle, mental-health, and medical-history data. It detects unusual patterns, estimates selected health risks, answers questions about the data, and creates reports.
