pptx-posters

创建和审计可编辑的科学海报,基于作者批准的内容和本地资源,生成无宏的PowerPoint (.pptx)文件。在需要交付PowerPoint研究/会议海报,并需通过物理尺寸、印刷、可访问性、来源追溯和包安全性检查时使用。

pptx-posters 是什么?

此技能专用于从作者批准的本地内容和资产生成可编辑、无宏的PowerPoint科学海报。它严格遵循一系列硬性门控条件,确保生成过程安全可靠:作者必须提供精确内容并确认批准,所有来源和资源必须有确切记录和哈希校验,必须确认会议和打印机的具体要求,并且拒绝所有包含宏或外部依赖的不安全文件。生成过程使用 `python-pptx`、`Pillow` 和 `lxml` 库,仅创建一个空白演示文稿并严格按照清单添加本机文本框和图片,避免任何网络请求或外部模板。生成后,该技能会执行多项技术审计,包括安全检查(如检测宏、外部关系、恶意ZIP路径)、布局验证(边界、重叠、阅读顺序、最终字体DPI)以及可访问性评估(对比度、替代文本),最终输出的PowerPoint文件只有经过手动可访问性检查和作者签收后才算完成。它适用于所有支持Python脚本和PowerPoint的平台,如Claude Code、Cursor等,并要求用户手动在PowerPoint中完成最终的验证步骤。

PPTX 海报

范围

仅当请求的源文件/交付物是可编辑的PowerPoint海报时使用此技能。不要仅仅因为PowerPoint可用就将未明确指明的海报请求路由到此。

2.0版根据严格的本地JSON生成真正的单幻灯片 .pptx 文件。它不使用HTML转换、外部模板、示意图/图像生成服务、API密钥、环境文件、网络请求或强制性图形样式。

硬性门控

当任何门控条件未满足时,停止处理,而非猜测:

  1. 作者未提供确切的海报内容和来源记录。
  2. 任何声明、数字、引用、作者、单位、资金声明、图片、许可或二维码目标未得到解析。
  3. 当前的会议和打印要求未得到确认。
  4. 作者批准未绑定到当前清单内容哈希。
  5. 某个资产是远程的、不在清单目录内、未哈希或未批准。
  6. 输入是 .pptm 文件,包含宏/外部关系/OLE/嵌入式文件,或是不受信任的模板。
  7. 请求的工作流需要自动打开或执行PowerPoint。
  8. 某个脚本报告了包、布局、DPI、对比度或输出计划方面的阻止问题。

切勿捏造缺失的材料或留下看似合理的占位符。草稿以失败告终。

安装确切的生成依赖

在技能目录中:

uv venv
uv pip install "python-pptx==1.0.2" "Pillow==12.3.0" "lxml==6.1.1"

生成需要确切版本:

python-pptx==1.0.2
Pillow==12.3.0
lxml==6.1.1

所有CLI都使用惰性可选导入,因此 python -B scripts/<tool>.py --help 无需这些包即可运行。使用 -B 以避免生成字节码工件。

在布局前确定要求

分别记录以下内容:

  • 物理画板的裁剪宽度/高度和方向;
  • 每条边上的出血尺寸;
  • 裁剪线内的安全边距;
  • PowerPoint画布宽度/高度;
  • 统一的物理画板/画布打印比例;
  • 会议的最大尺寸和交付格式;
  • 打印机的裁剪、出血、边距、缩放、色彩模式和打样要求;
  • 最终输出的字体和光栅DPI阈值,每个都标记为启发式或绑定到确切源。
  • 所需的字体、工作站可用性、嵌入权限以及替换/打样工作流。

没有通用的海报尺寸。Microsoft当前将每个自定义PowerPoint尺寸限制为1–56英寸,并且所有幻灯片使用同一尺寸。如果物理画板更大,仅在打印机确认缩放后才使用按比例的画布。

阅读 references/poster_layout_design.md。

构建清单

将 assets/poster_manifest_template.json 复制到项目中。该模板在每一个替换令牌、错误确认和草稿批准被解决之前,是故意无效的。

遵循 references/manifest_spec.md 和 references/poster_content_guide.md。

清单要求:

  • 文档元数据、每个元素和每个资产的确切来源ID;
  • 每个来源上的 author_verified: true;
  • 每个元素和资产上的 author_approved: true;
  • 本地PNG/JPEG路径和小写SHA-256哈希值;
  • 每个可选图片的确切来源归属和许可/权限;
  • 已批准的替代文本,以及必要时绑定来源的原生长描述;
  • 明确的阅读顺序和设计矩形;
  • 每个本地二维码图像的可见确切回退URL/文本;
  • 已确认的会议/打印机规则;
  • 声明的sRGB对比度对和冗余数据编码;
  • 批准绑定到规范的清单内容。

在所有非批准字段通过后,获取内容哈希:

python -B scripts/validate_manifest.py poster.json \
  --print-content-hash

将确切的清单和哈希值提供给作者。然后将 approval.status 设置为 approved,记录批准人和偏移感知时间戳,并复制哈希值。任何非批准的编辑都会使批准失效。

验证已批准的清单和本地资产:

python -B scripts/validate_manifest.py poster.json

在生成前审计资产和调色板

python -B scripts/inventory_images.py poster.json \
  --output poster.assets.json

python -B scripts/check_palette.py poster.json \
  --output poster.palette.json

python -B scripts/plan_export.py poster.json \
  --output poster.export-plan.json

有效DPI是像素数除以最终放置的英寸数,而不是图像元数据中的DPI。清单完全解码有界图像并阻止EXIF/XMP/注释以及嵌入的文本/应用程序元数据;离线清理这些内容,然后重新哈希并重新批准资产。对比度使用WCAG 2.2 sRGB数学计算;将这些值应用于物理海报是一个设计目标,而非独立的合规性声明。保留颜色冗余的标签、标记、形状、图案或线型。

如果打印机需要CMYK,则输出计划会阻止打印就绪状态,直到存在打印机批准的转换/配置文件和打样。不要声称原生PowerPoint PDF是CMYK兼容的。

阅读 references/poster_design_principles.md。

生成PPTX

使用新的输出路径:

python -B scripts/generate_poster.py poster.json \
  --output poster.pptx \
  --report poster.generation.json

生成过程:

  • 创建一个新的空白演示文稿;它从不加载用户模板;
  • 在添加内容前设置已批准的画布;
  • 使用一个原生标题占位符、原生文本框和本地图片;
  • 使用 contain 适配保持图像宽高比;
  • 禁用文本自动收缩;
  • 按已批准的阅读顺序添加元素;
  • 将已批准的图片替代描述和明确的文本语言写入PresentationML;
  • 不嵌入字体、音频、视频、OLE、ActiveX、链接或其他媒体;
  • 移除默认的打印机设置二进制数据并规范化包时间戳;
  • 在替代文本修补前后检查包;
  • 拒绝重叠、越界形状、最终字体大小/DPI过低、不安全的包和已经存在的目标。

它渲染确切的清单文本。它不撰写、总结、研究或更正科学内容。

运行最终技术审计

python -B scripts/inspect_pptx.py poster.pptx \
  --output poster.package.json

python -B scripts/check_layout.py poster.pptx \
  --manifest poster.json \
  --output poster.layout.json

包检查器仅读取有界的ZIP元数据和选定的XML。它从不提取成员或打开/执行演示文稿。它拒绝:

  • 每一个非 .pptx 扩展名,包括 .pptm;
  • 位于有界单幻灯片生成器配置文件之外的包;
  • 宏/VBA、ActiveX、自定义UI、OLE、嵌入式、可执行文件和二进制部件;
  • 每一个外部关系,包括远程链接图像和超链接;
  • 不安全/重复的ZIP路径、符号链接、加密、过大扩展和过度压缩比;
  • 格式错误或包含实体的被检查XML;
  • 缺失的内部关系目标。

阅读 references/pptx_security.md。

手动PowerPoint和可访问性门控

自动化无法认证可访问性、文本渲染或科学准确性。在完全修补过的PowerPoint中:

  1. 仅打开已生成且技术上清洁的文件。
  2. 运行“审阅 > 检查辅助功能”。
  3. 检查“阅读顺序”窗格和对象名称。
  4. 检查所有替代文本和原生长描述。
  5. 测试键盘和屏幕阅读器导航。
  6. 确认字体已安装/已授权;检查嵌入选择、替换、字形、方程式、溢出、对比度和所有边缘。
  7. 验证颜色不是唯一的编码方式。
  8. 测试每个二维码及其可见的回退URL/文本。
  9. 获取作者对所有内容和引用的签收。

Microsoft的18磅幻灯片建议并非通用海报最小值。使用清单中标记的基础和打样,在最终物理输出上评估字体大小。

导出和打印

使用已批准的导出计划。当需要PDF时,从审阅过的PowerPoint使用“标准/高质量打印”而非“最小尺寸”导出。

独立验证PDF:

  • 页面/画板尺寸、方向、裁剪和出血;
  • 如果需要,单页输出;
  • 字体、裁剪、字形、方程式和图像重采样;
  • 标签、阅读顺序、替代文本、语言和链接;
  • RGB/CMYK转换和物理色彩打样;
  • 会议命名、文件大小和上传规则。

打印缩小比例的打样并获取打印机要求的打样。在任何更改后重新运行所有检查。

使用 assets/poster_quality_checklist.md 进行发布签收。

adaptyv

How to use the Adaptyv Bio Foundry API and Python SDK for protein experiment design, submission, and results retrieval. Use this skill whenever the user mentions Adaptyv, Foundry API, protein binding assays, protein screening experiments, BLI/SPR assays, thermostability assays, or wants to submit protein sequences for experimental characterization. Also trigger when code imports `adaptyv`, `adaptyv_sdk`, or `FoundryClient`, or references `foundry-api-public.adaptyvbio.com`.

aeon

This skill should be used for time series machine learning tasks including classification, regression, clustering, forecasting, anomaly detection, segmentation, and similarity search. Use when working with temporal data, sequential patterns, or time-indexed observations requiring specialized algorithms beyond standard ML approaches. Particularly suited for univariate and multivariate time series analysis with scikit-learn compatible APIs.

alphagenome

Look up precomputed AlphaGenome Atlas effects for any GRCh38 single-nucleotide variant (AVI score with Phred and 18 SHAP feature attributions, plus raw and quantile scores for RNA-seq, DNase, ATAC, ChIP-TF, ChIP-histone, CAGE, PRO-cap, splicing, polyadenylation and contact-map tracks), score variants or scan windows on demand with the AlphaGenome model for human and mouse (variant scoring, in silico mutagenesis, REF-versus-ALT track prediction), and build Atlas website deep links. Use when the user mentions AlphaGenome, AlphaGenome Atlas, AVI or AlphaGenome Variant Impact, DeepMind variant effect prediction, or wants to prioritise or mechanistically interpret non-coding, regulatory, splicing, enhancer, promoter, or chromatin-accessibility effects of SNVs from a VCF, credible set, or region. Research use only; not a clinical tool.

analytical-method-validation

Plan, execute, and document validation, verification, and transfer of analytical procedures under the governing framework - ICH Q2(R2) and Q14, USP <1220>/<1225>/<1226>, ICH M10 bioanalytical, CLSI EP, or ISO/IEC 17025. Use for HPLC, LC-MS/MS, GC, CE, ICP-MS, dissolution, qNMR, qPCR, NIR, and ligand binding or cell-based assays whenever the question is whether a procedure is fit for its intended purpose. Triggers include

anndata

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.

arbor

Autonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g.

arboreto

Infer gene regulatory networks (GRNs) from gene expression data using scalable algorithms (GRNBoost2, GENIE3). Use when analyzing transcriptomics data (bulk RNA-seq, single-cell RNA-seq) to identify transcription factor-target gene relationships and regulatory interactions. Supports distributed computation for large-scale datasets.

astropy

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bioservices

Unified Python interface to 40+ bioinformatics services. Use when querying multiple databases (UniProt, KEGG, ChEMBL, Reactome) in a single workflow with consistent API. Best for cross-database analysis, ID mapping across services. For quick single-database lookups use gget; for sequence/file manipulation use biopython.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
