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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 173 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00081 | $0.04053 |
| Opus 5.5 | $0.00032 | $0.01621 |
| Sonnet 5.5 | $0.00016 | $0.00811 |
| Haiku 4.5 | $0.00008 | $0.00405 |
Grade A, and why
generate-image scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s https://openrouter.ai/api/v1/images \ How it starts
The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate Image
Generate and edit images through OpenRouter's Image API, which reaches Gemini, Seedream, Recraft, GPT-Image, Riverflow, and roughly thirty other models behind one request shape.
When to use
Use this skill for: photos and photorealistic images, illustrations and artwork, concept art, presentation and poster visuals, logos and vector marks, image editing, and compositing from reference images.
Use scientific-schematics instead for: flowcharts, circuit diagrams, biological pathways,
system architecture diagrams, CONSORT diagrams, and other technical schematics.
API key
Generation requires an OpenRouter key. The script resolves it in this order:
--api-key- the
OPENROUTER_API_KEYenvironment variable OPENROUTER_API_KEY=in a.envfile, searching the working directory upward, then the script's own directory
If none is present the script exits with setup instructions. Keys: https://openrouter.ai/keys
--list-models, --model-info, and --dry-run need no key.
Quick start
# Generate
python scripts/generate_image.py "A beautiful sunset over mountains"
# Edit an existing image
python scripts/generate_image.py "Make the sky purple" -i photo.jpg -o edited.png
Paths are relative to this skill's directory. Output defaults to generated_image.<ext>, where the
extension follows the media type the model returned. The per-request cost is printed after the run.
Then look at the image. Read the file back and check it before using it anywhere: composition, aspect ratio, and any text are all things models get wrong silently.
Choosing a model
Default: google/gemini-3.1-flash-image.
| Need | Model |
|---|---|
| General quality, prompt adherence | google/gemini-3.1-flash-image |
| Highest Gemini tier | google/gemini-3-pro-image |
| Cheap iteration | google/gemini-3.1-flash-lite-image (1K only), openai/gpt-image-1-mini |
| Photoreal control, reproducible seeds | bytedance-seed/seedream-4.5 |
| Several images per request | bytedance-seed/seedream-4.5, openai/gpt-image-2 (up to 10) |
| Vector / SVG output | recraft/recraft-v4.1-vector |
| Transparent background | openai/gpt-image-1 with --background transparent |
| Legible text inside the image | recraft/recraft-v4.1, sourceful/riverflow-v2.5-pro — see the caveat below |
What ships with it
2 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.

generate-image 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 81 tokens to every session and 4,053 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
