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.

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 | $0.00059 | $0.02448 |
| Opus 5.5 | $0.00024 | $0.00979 |
| Sonnet 5.5 | $0.00012 | $0.00490 |
| Haiku 4.5 | $0.00006 | $0.00245 |
Grade A, and why
pptx-posters 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.
This is a copy
86% identical to pptx-posters — 37 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PPTX posters
Scope
Use this skill only when the requested source/deliverable is an editable PowerPoint poster. Do not route an unspecified poster request here merely because PowerPoint is available.
Version 2.0 generates a real one-slide .pptx from strict local JSON. It does not use
HTML conversion, external templates, schematic/image-generation services, API keys,
environment files, network requests, or mandatory figure styles.
Hard gates
Stop instead of guessing when any gate is unmet:
- The author has not supplied exact poster content and source records.
- Any claim, number, citation, author, affiliation, funding statement, figure, license, or QR target is unresolved.
- Current conference and printer requirements are not confirmed.
- Author approval is not bound to the current manifest content hash.
- An asset is remote, outside the manifest directory, unhashed, or unapproved.
- An input is
.pptm, contains macros/external relationships/OLE/embedded files, or is an untrusted template. - The requested workflow needs PowerPoint to be opened or executed automatically.
- A script reports a package, layout, DPI, contrast, or output-plan blocker.
Never fabricate missing material or leave a plausible placeholder. Drafts fail closed.
Install exact generation dependencies
From the skill directory:
uv venv
uv pip install "python-pptx==1.0.2" "Pillow==12.3.0" "lxml==6.1.1"
Generation requires exactly:
python-pptx==1.0.2
Pillow==12.3.0
lxml==6.1.1
All CLIs use lazy optional imports, so python -B scripts/<tool>.py --help works
without these packages. Use -B to avoid bytecode artifacts.
Establish requirements before layout
Record these separately:
- physical trim width/height and orientation;
- bleed on each edge;
- safe margin inside trim;
- PowerPoint canvas width/height;
- uniform physical-artboard/canvas print scale;
- conference maximum dimensions and delivery format;
- printer trim, bleed, margin, scaling, color-mode, and proof requirements;
- final-output font and raster-DPI thresholds, each labeled as a heuristic or tied to an exact source.
- required font faces, workstation availability, embedding permission, and the substitution/proof workflow.

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.

pptx-posters 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 59 tokens to every session and 2,448 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to pptx-posters, differing in 37 lines, and is treated as a copy.
