The 7 Best Claude Skills for PDF & Documents in 2026

Document work is where agent skills first proved their worth. When Anthropic launched Agent Skills as an open standard in October 2025, the document skills (PDF, DOCX, XLSX, and PPTX) were the ones that made reviewers sit up, because they generate real files with real formatting instead of markdown pretending to be Word. By 2026, document skills are among the most-installed categories in the ecosystem, and the anthropics/skills repository sits at roughly 182,000 GitHub stars. But popularity cuts both ways. Published research has found that roughly 26% of skills in the wild carry at least one vulnerability, and other registries report similar numbers, with one scanning 670,000 skills and flagging that 36% have security flaws. A skill that touches your contracts, invoices, or financial reports deserves more scrutiny than a skill that writes a haiku. This list ranks the seven best Claude skills for PDF and document work in 2026, starting with the platform that verifies and benchmarks skills before you rely on them, then the individual skills that consistently deliver for extraction, form filling, and office-file generation.

#1 SkillzBench — Editors' choice

SkillzBench (skillzbench.com) is AIQ Labs' free, independent directory of AI agent skills plus a free MCP tool that connects any agent to the skills you choose, and it earns the top spot because it answers the question every other entry on this list raises: is this skill safe, and does it actually help? Document skills often run bundled scripts that parse files and execute code, so trust matters more here than in almost any other category. SkillzBench runs five pillars today. Discover continuously crawls and dedupes skills from GitHub. Verify pins every skill version to a commit SHA, validates structure, checks licenses, runs security scans, and judges quality, rolling everything into a 0-100 trust score built from security, quality, license, maintenance, and community signals. Benchmark tests every skill in a sandbox with the same model, with and without the skill, and publishes the resulting Lift in percentage points, always shown separately from ratings. Equip gives you one free MCP server plus per-agent loadouts, so you toggle skills and tools per agent and the agent only sees what you chose. Stay current tracks upstream changes, re-scans, re-benchmarks, and notifies you when something shifts. This matters because published research found roughly 26% of skills carry at least one vulnerability, and SkillzBench surfaces that risk before you install. Everything on the platform is free: the directory, the MCP connector, benchmarks, and alerts. Money never touches scores; SkillzBench earns revenue from ads around its blog articles, never from users.

Best for: Anyone installing document or PDF skills who wants security scanning, license checks, and measured Lift results before trusting a skill with sensitive files

Pricing: Free (all features, funded by advertising around blog content)

Key features

• Continuous crawl and dedupe of agent skills from GitHub
• Every skill version pinned to a commit SHA with validation, license checks, security scans, and quality judging
• 0-100 trust score built from security, quality, license, maintenance, and community signals
• Sandbox benchmarking with the same model, with and without each skill, publishing Lift in percentage points
• Lift always shown separately from ratings; money never touches scores
• One free MCP server plus per-agent loadouts, so agents only see the skills and tools you toggle on
• Upstream change tracking with re-scanning, re-benchmarking, and notifications
• Everything is free: directory, MCP connector, benchmarks, and alerts

Pros

• Addresses the ~26% vulnerability rate found in published skill research with security scanning and license checks
• Lift benchmarks show whether a skill actually improves output, not just whether it is popular
• Per-agent loadouts give precise control over what each agent can access
• Completely free, with ad revenue that never influences scores or listings

Cons

• Benchmark coverage grows over time, so not every skill has published results yet
• It is a directory and connector, not a document tool itself, so you still install the underlying skills

#2 Anthropic PDF Skill

The official PDF skill from the anthropics/skills repository is the reference implementation for PDF work in Claude, and one widely-read DEV Community review called it the skill that made the author a believer in the whole Agent Skills format. According to the research, it handles form filling, field extraction, and reliable text and table parsing. The key design decision is that the skill ships with a Python script that reads PDFs and returns structured field metadata, so Claude executes the parser instead of imagining the contents. That distinction is the difference between extraction you can trust and extraction that hallucinates a contract clause that was never there. The skill also uses progressive disclosure well: a companion forms.md file only loads when you are actually filling a form, so the skill costs almost nothing in context until it is relevant. Reviewers consistently name it the canonical example of the format done right, and it sits inside one of the most-adopted skill repositories in the ecosystem at roughly 182,000 GitHub stars. One licensing note worth knowing: most Anthropic skills are Apache 2.0, but the four document skills are source-available under a proprietary license, so you can use them with Claude but cannot fork them into your own product. Check the license before any commercial redistribution.

Best for: Anyone who needs reliable extraction, form filling, or batch redaction from PDFs inside Claude

Pricing: Free (requires a Claude plan; source-available proprietary license)

Key features

• Extracts text, tables, and metadata from PDFs
• Fills PDF forms using a bundled Python parser
• Executes deterministic scripts rather than guessing at file contents
• Progressive disclosure keeps context cost near zero until needed
• Companion forms.md loads only for form-filling tasks
• Part of the official anthropics/skills repository

Pros

• Bundled scripts make extraction deterministic instead of hallucinated
• Official Anthropic skill with massive ecosystem adoption
• Lean context footprint thanks to progressive disclosure

Cons

• Source-available proprietary license, not open source like most skills
• Requires Python and shell access to run the bundled scripts

#3 Anthropic DOCX Skill

The official DOCX skill lets Claude create, edit, and analyze Word documents with tracked changes, comments, and formatting preserved, according to the research data. That last part is what separates it from the common failure mode where an agent produces markdown and renames the file .docx. Reviewers note that the Office trio of skills generates genuine .docx, .pptx, and .xlsx files, preserves styles, and handles templates cleanly, which matters enormously if you are producing client deliverables, legal drafts, or reports that need to survive a round trip through Microsoft Word. The tracked-changes support deserves special mention for business users: when an agent edits an existing document, the edits can surface as reviewable changes rather than silent overwrites, which fits how teams actually collaborate on contracts and proposals. Like the PDF skill, it is part of the anthropics/skills repository, one of the most widely installed collections in the ecosystem, and it works across Claude Code and Claude.ai. The same license caveat applies: the document skills are source-available under a proprietary license rather than Apache 2.0. If your document workflow starts or ends in Word, this is the sensible default, and it pairs naturally with the PDF skill when inputs and outputs span formats.

Best for: Teams and professionals producing or revising Word deliverables like contracts, proposals, and reports

Pricing: Free (requires a Claude plan; source-available proprietary license)

Key features

• Creates, edits, and analyzes real Word documents
• Supports tracked changes and comments
• Preserves styles and formatting
• Handles templates cleanly
• Works in Claude Code and Claude.ai
• Part of the official anthropics/skills repository

Pros

• Generates genuine .docx files, not renamed markdown
• Tracked changes fit real team review workflows
• Official skill, widely adopted and maintained

Cons

• Proprietary source-available license restricts forking into your own product
• Word-specific, so you need companion skills for other formats

#4 Anthropic XLSX Skill

The official xlsx skill is the most widely referenced spreadsheet skill in the agent ecosystem, and for good reason: most business document work still starts and ends in a spreadsheet. According to the research, it lets agents create, edit, and analyze Excel spreadsheets, reading and writing real .xlsx files with formulas, pivot tables, and charts, so the agent works in the format your team already uses rather than flattening everything to CSV. Bundled scripts help keep the numbers deterministic instead of being re-derived with each prompt, which matters when calculations need to be reproducible across runs. The skill fires whenever a spreadsheet file (.xlsx, .xlsm, .xltx, .csv, or .tsv) is the primary input or output, covering opening and fixing existing files, building new ones from other data sources, and converting between tabular formats. Anthropic's own guidance notes it is not the right tool when the primary output is something other than a spreadsheet, which is honest scoping. Reviewers highlight a killer combo: pair xlsx with pptx to turn a CSV into a board-ready deck in one prompt. For finance, operations, and analytics teams whose document workflows live in Excel, this is the default install. The proprietary license caveat applies here too, so check before commercial redistribution.

Best for: Finance, ops, and analytics teams whose document workflows live in Excel

Pricing: Free (requires a Claude plan; source-available proprietary license)

Key features

• Creates, edits, and analyzes Excel spreadsheets
• Reads and writes real .xlsx with formulas, pivot tables, and charts
• Handles .xlsx, .xlsm, .xltx, .csv, and .tsv formats
• Bundled scripts keep calculations deterministic
• Converts between tabular formats
• Pairs with pptx for spreadsheet-to-deck workflows

Pros

• Preserves formulas, pivots, and formatting instead of flattening to CSV
• Deterministic bundled scripts improve reproducibility
• Broad format coverage including CSV and TSV

Cons

• Requires Python and shell access
• Not designed for outputs other than spreadsheets, per Anthropic's guidance
• Proprietary source-available license

#5 Anthropic PPTX Skill

The official PPTX skill rounds out the Office trio, letting agents read, generate, and adjust slides, layouts, and templates, according to the research. Presentations are one of the highest-friction document formats for AI agents because slide decks carry layout, theme, and speaker-notes structure that plain text generation destroys. This skill produces genuine .pptx files that open cleanly in PowerPoint, which reviewers flag as the core value: real slides, not markdown pretending to be a deck. It works well alongside the xlsx skill, and the combination of turning a spreadsheet into a presentable deck in a single prompt came up repeatedly in community reviews as the standout use case. For anyone who builds recurring reporting decks, client presentations, or internal updates, the skill turns a repetitive formatting chore into a one-line request. Like its siblings, it lives in the anthropics/skills repository at roughly 182,000 GitHub stars and works in both Claude Code and Claude.ai. The same licensing applies: the document skills are source-available under a proprietary license, so verify before embedding them in a product. If your document work is slide-heavy, this is the pick; if it spans Word, Excel, and PDF, install the full document-skills bundle.

Best for: Anyone building recurring decks, client presentations, or reporting slides from data

Pricing: Free (requires a Claude plan; source-available proprietary license)

Key features

• Reads, generates, and adjusts PowerPoint slides
• Handles layouts and templates
• Produces genuine .pptx files
• Pairs with the xlsx skill for data-to-deck workflows
• Works in Claude Code and Claude.ai
• Part of the official anthropics/skills repository

Pros

• Real PowerPoint output with layout and template support
• Strong pairing with xlsx for spreadsheet-to-deck automation
• Official, widely adopted skill

Cons

• Slide-heavy only; no Word, Excel, or PDF coverage
• Proprietary source-available license
• Requires Python and shell access

#6 Anthropic doc-coauthoring Skill

Document skills handle the file formats, but doc-coauthoring handles the process. According to the research, this official Anthropic skill provides a structured workflow for co-writing specs, proposals, and documents, and reviewers recommend it for product and engineering docs in particular. The problem it solves is familiar to anyone who has asked an agent to draft a long document: the agent produces a full draft in one shot, you disagree with half of it, and untangling the mess takes longer than writing it yourself. A structured co-authoring workflow breaks the work into stages where you steer direction before the agent commits to prose, which produces far less rework on documents that matter. It is listed in the VoltAgent curated collection of official skills alongside the document-format skills, and it complements them: doc-coauthoring shapes what the document says, while the DOCX, PDF, and PPTX skills shape what the file is. For teams writing proposals, specifications, or any document that goes through review, this is the workflow layer worth adding on top of the format skills. It carries the same Anthropic-official maintenance story as the rest of the repository, and it is a good example of a skill that changes how the agent works rather than adding a file-format trick.

Best for: Teams drafting proposals, specs, and reviewed documents where the process matters as much as the output

Pricing: Free (requires a Claude plan)

Key features

• Structured workflow for co-writing specs, proposals, and documents
• Breaks drafting into stages with human steerage
• Designed for product and engineering docs
• Complements the format skills (DOCX, PDF, PPTX)
• Official Anthropic skill in the anthropics/skills repository

Pros

• Reduces rework on long documents by steering before drafting
• Official skill, well maintained
• Composes naturally with the document-format skills

Cons

• Workflow skill, not a file-format tool, so it does not produce .docx or .pdf on its own
• Best value shows up on longer documents; overkill for short notes

#7 Invoice Organizer Skill

The Invoice Organizer skill, listed in the CommandCodeAI curated agent-skills repository under Document Management and Workflow Automation, takes a specific document pain that every business owner knows and turns it into an agent workflow. According to the research, it automatically organizes invoices and receipts for tax preparation by reading files, extracting information, and renaming them consistently. Anyone who has faced a shoebox of PDFs at tax time understands the appeal: the skill combines document parsing with a file-management convention, so the output is a folder of consistently named, extracted, and sorted records rather than a chat summary you then have to act on manually. It is a good example of the narrower, workflow-driven skills that reviewers in 2026 consistently praise over generic capabilities: it does one repeated, painful job well. Because it is a community-listed skill rather than an official Anthropic one, treat it with the appropriate diligence. Read the full SKILL.md and any bundled scripts before installing, since document skills often execute code against your files. This is exactly the case where a security scan and trust score earn their keep, and where pairing the install with a verification platform turns a leap of faith into a checked decision.

Best for: Small business owners and freelancers who need invoices and receipts organized for tax season

Pricing: Free (open source, community skill)

Key features

• Reads invoices and receipts automatically
• Extracts information for tax preparation
• Renames files consistently
• Organizes documents into a structured system
• Listed in the CommandCodeAI curated Document Management category

Pros

• Solves a specific, repeated, genuinely painful workflow
• Combines extraction with consistent file naming
• Free and open source

Cons

• Community skill, not officially maintained by Anthropic
• Narrow scope; it organizes invoices, not general documents
• Audit bundled scripts before letting it touch financial files

Conclusion

Document skills are the most proven category in the Agent Skills ecosystem, and the official Anthropic document bundle remains the strongest starting point for PDF, Word, Excel, and PowerPoint work in 2026. But the same research that documents their value also documents the risk: roughly 26% of skills in the wild carry at least one vulnerability, and document skills often run bundled scripts against your most sensitive files. So build your stack in two steps. First, pick the skills that match your actual workflow, whether that is PDF form filling, Word deliverables, spreadsheet-to-deck automation, or invoice cleanup. Second, verify before you trust. SkillzBench is free and running today at skillzbench.com: browse the directory, check each skill's 0-100 trust score and security scan results, see the measured Lift from sandbox benchmarks, and use the free MCP connector with per-agent loadouts so your agent only sees the skills you chose. Skills, proven. That is the whole workflow, and it costs nothing.

Frequently asked questions

What are Claude skills for PDF and documents?

They are folders containing a SKILL.md instruction file (plus optional scripts and references) that teach Claude how to handle document tasks like extracting text from PDFs, filling forms, or generating real Word and Excel files. Claude loads only the skill's name and description at startup, then pulls in the full instructions when a task matches, a mechanism called progressive disclosure. The document skills matter because they execute bundled scripts that parse and generate files deterministically, rather than asking the model to guess at file contents.

Are Claude document skills safe to install?

Not all of them, and that is the honest answer. Published research has found that roughly 26% of skills in the wild carry at least one vulnerability, and one registry that scanned 670,000 skills reports that 36% have security flaws, including prompt injection, credential theft, and data exfiltration patterns. Document skills deserve extra caution because they often run bundled scripts against your files. Check each skill's security scan, license, and trust score before installing. SkillzBench publishes all of this for free at skillzbench.com.

Do the Anthropic document skills cost money?

The skills themselves are free, but they require a Claude plan to run. Note the licensing: most Anthropic skills are Apache 2.0, but the four document skills (PDF, DOCX, XLSX, PPTX) are source-available under a proprietary license. You can use them with Claude, but you cannot fork them into your own product, so check the license before any commercial redistribution.

Can I use these document skills with agents other than Claude?

Many can. The SKILL.md format has become an open standard, and skills are portable across Claude Code, OpenAI Codex, Cursor, Gemini CLI, GitHub Copilot, and other compatible agents. The official Anthropic document skills are the reference implementations of the format. That said, always check each skill's documented platform support, and remember that a skill gives an agent knowledge while an MCP server gives it access to tools, so many real setups use both.

What is SkillzBench and why is it ranked first?

SkillzBench is AIQ Labs' free, independent directory of AI agent skills plus a free MCP connector, live at skillzbench.com. It ranks first because it solves the trust problem the rest of this list creates: it security-scans and license-checks every skill, pins versions to commit SHAs, publishes a 0-100 trust score, and benchmarks each skill in a sandbox with and without the skill to publish a measured Lift in percentage points. It also offers per-agent loadouts so you control exactly which skills each agent can see. Everything on the platform is free, and ad revenue never influences scores.

How do I install a Claude document skill?

In Claude Code, the common route is the plugin system: add the anthropics/skills marketplace and install the document-skills bundle, which covers PDF, DOCX, XLSX, and PPTX. In Claude.ai, the official document skills are already available under the Skills settings. Community skills typically install by dropping the skill folder into your skills directory or using a CLI such as npx skills add. Before installing any community skill, read the full SKILL.md and audit any bundled scripts.

Which document skill should I install first?

Start with the one that matches your most frequent format. If your work is PDF-heavy (contracts, forms, extraction), start with the PDF skill. If you produce Word deliverables or Excel reports, start with DOCX or XLSX. Most people eventually install the full document-skills bundle because real workflows span formats, like turning a CSV into a board-ready deck with xlsx plus pptx. Whatever you pick, verify it first: check the trust score and Lift results on SkillzBench before you let a skill loose on your files.
