An interactive PDF viewer for opening documents and working on them visually. PDF is a document format that preserves a file's layout across devices.

Use it to display PDFs, highlight or annotate pages, fill forms, add signatures or initials, apply stamps, and review markup.

It helps when reading a document together with someone and marking the document itself, rather than only extracting or summarizing its text.

view-pdf — Skill for Claude Code by anthropics

About the project

Knowledge Work Plugins is an open-source collection of Claude extensions organized around roles such as productivity, sales, and customer support. Each plugin combines role-specific guidance, connectors, commands, and sub-agents so knowledge workers can use Claude with their team’s tools and processes. The catalogue entries are examples of, or workflows from, this plugin collection.

Token cost

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	$0.00062	$0.01625
Opus 5	$0.00031	$0.00813
Sonnet 5	$0.00012	$0.00325
Haiku 4.5	$0.00006	$0.00162

Security

Grade A, and why

view-pdf 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 2d 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.

PDF Viewer — Interactive Document Workflows

You have access to a local PDF server that renders documents in a live viewer and lets you annotate, fill forms, and place signatures with real-time visual feedback.

When to use this skill

Use the PDF viewer when the user wants interactivity:

"Show me this contract" / "Open this paper"
"Highlight the key terms and let me review"
"Help me fill out this form"
"Sign this on page 3" / "Add my initials to each page"
"Stamp this CONFIDENTIAL" / "Mark this as approved"
"Walk me through this document and annotate the important parts"

Do NOT use the viewer for pure ingestion:

"Summarize this PDF" → use the native Read tool directly
"What does page 5 say?" → use Read
"Extract the table from section 3" → use Read

The viewer's value is showing the user the document and collaborating on markup — not streaming text back to you.

Tools

`list_pdfs`

List available local PDFs and allowed local directories. No arguments.

`display_pdf`

Open a PDF in the interactive viewer. Call once per document.

url — local file path or HTTPS URL
page — initial page (optional, default 1)
elicit_form_inputs — if true, prompts the user to fill form fields before displaying (use for interactive form-filling)

Returns a viewUUID — pass this to every interact call. Calling display_pdf again creates a separate viewer; interact calls with the new UUID won't reach the one the user is looking at.

Also returns formFields (name, type, page, bounding box) if the PDF has fillable fields — use these coordinates for signature placement.

`interact`

All follow-up actions after display_pdf. Pass viewUUID plus one or more commands. Batch multiple commands in one call via the commands array — they run sequentially. End batches with get_screenshot to verify changes visually.

Annotation actions:

add_annotations — add markup (see types below)
update_annotations — modify existing (id + type required)
remove_annotations — delete by id array
highlight_text — auto-find text by query and highlight it (preferred over manual rects for text markup)

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.

view-pdf is a skill published in the GitHub repository anthropics/knowledge-work-plugins (23,911 stars, last pushed 2d ago), licensed Apache-2.0. It adds 62 tokens to every session and 1,625 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
