The PDF skill provides tools and workflows for reading, creating, and validating PDF files where visual layout and rendering are critical. Use it to programmatically generate PDFs with reportlab, extract text with pdfplumber or pypdf, and visually verify output by rendering pages to PNG images using Poppler before delivery to ensure proper alignment, spacing, typography, and absence of rendering artifacts.

# PDF Skill ## When to use - Read or review PDF content where layout and visuals matter. - Create PDFs programmatically with reliable formatting. - Validate final rendering before delivery. ## Workflow 1. Prefer visual review: render PDF pages to PNGs and inspect them. - Use `pdftoppm` if available. - If unavailable, install Poppler or ask the user to review the output locally. 2. Use `reportlab` to generate PDFs when creating new documents. 3. Use `pdfplumber` (or `pypdf`) for text extraction and quick checks; do not rely on it for layout fidelity. 4. After each meaningful update, re-render pages and verify alignment, spacing, and legibility. ## Temp and output conventions - Use `tmp/pdfs/` for intermediate files; delete when done. - Write final artifacts under `output/pdf/` when working in this repo. - Keep filenames stable and descriptive. ## Dependencies (install if missing) Prefer `uv` for dependency management. Python packages: ``` uv pip install reportlab pdfplumber pypdf ``` If `uv` is unavailable: ``` python3 -m pip install reportlab pdfplumber pypdf ``` System tools (for rendering): ``` # macOS (Homebrew) brew install poppler # Ubuntu/Debian sudo apt-get install -y poppler-utils ``` If installation isn't possible in this environment, tell the user which dependency is missing and how to install it locally. ## Environment No required environment variables. ## Rendering command ``` pdftoppm -png $INPUT_PDF $OUTPUT_PREFIX ``` ## Quality expectations - Maintain polished visual design: consistent typography, spacing, margins, and section hierarchy. - Avoid rendering issues: clipped text, overlapping elements, broken tables, black squares, or unreadable glyphs. - Charts, tables, and images must be sharp, aligned, and clearly labeled. - Use ASCII hyphens only. Avoid U+2011 (non-breaking hyphen) and other Unicode dashes. - Citations and references must be human-readable; never leave tool tokens or placeholder strings. ## Final checks - Do not deliver until the latest PNG inspection shows zero visual or formatting defects. - Confirm headers/footers, page numbering, and section transitions look polished. - Keep intermediate files organized or remove them after final approval.
Agent-browser usage guide. Read this before running any agent-browser commands. Covers the snapshot-and-ref workflow, navigating pages, interacting with elements (click, fill, type, select), extracting text and data, taking screenshots, managing tabs, handling forms and auth, waiting for content, running multiple browser sessions in parallel, and troubleshooting common failures. Use when the user asks to interact with a website, fill a form, click something, extract data, take a screenshot, log into a site, test a web app, or automate any browser task.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
Manages MongoDB Atlas Stream Processing (ASP) workflows. Handles workspace provisioning, data source/sink connections, processor lifecycle operations, debugging diagnostics, and tier sizing. Supports Kafka, Atlas clusters, S3, HTTPS, and Lambda integrations for streaming data workloads and event processing. NOT for general MongoDB queries or Atlas cluster management. Requires MongoDB MCP Server with Atlas API credentials.
This skill should be used when user asks to "query Azure resources", "list storage accounts", "manage Key Vault secrets", "work with Cosmos DB", "check AKS clusters", "use Azure MCP", or interact with any Azure service.
This skill should be used when user asks to "clean gone branches", "remove deleted local branches", "prune branches removed from remote", or explicitly invokes "clean-gone-branches".
Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.
This skill should be used when user asks to "commit these changes", "write commit message", "stage and commit", "create a commit", "commit staged files", or explicitly invokes "commit-staged".
This skill should be used when user asks to "create a PR", "make a pull request", "open PR for this branch", "submit changes as PR", "push and create PR", or explicitly invokes "create-pr".
