An interactive PDF viewer for reviewing documents visually and adding annotations, filling forms, or placing signatures and initials. It is intended for collaborative document work, not plain text extraction.

Use it to display PDFs, mark important sections, fill fields, add review notes, stamp pages, and place visual signatures.

It lets you see the document and review each change directly instead of relying only on extracted text or a success message.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add skills/warroom-ceo/core/view-pdf

Any agent

npx skills add WARROOM-CEO/CORE --skill view-pdf

Clone the repo

git clone --depth 1 https://github.com/WARROOM-CEO/CORE

Made for: Claude Code, Codex.

Or install pdf-viewer, the plugin that ships this one along with the rest of its 1 skill, 8 commands.

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	$0.00101	$0.01719
Opus 5	$0.00051	$0.00860
Sonnet 5	$0.00020	$0.00344
Haiku 4.5	$0.00010	$0.00172

Security

Grade A, and why

view-pdf-th 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Language: All user-facing output — responses, summaries, and any text the user will read — must be written in Thai (ภาษาไทย). Internal logic, file paths, code snippets, and technical values remain in English.

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-th 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-th page"
"Stamp this CONFIDENTIAL" / "Mark this as-th 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.

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.

view-pdf-th is a skill published in the GitHub repository WARROOM-CEO/CORE (30 stars, last pushed 5mo ago), licensed MIT. It adds 101 tokens to every session and 1,719 once invoked, about $0.0005 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 2026-09-03.
