open

open is a command for Claude Code from eigenweltlabs/legalwork. It costs 9 tokens per session (259 once invoked), scanned A, original, MIT.

A command that opens a PDF in the app's viewer panel. It finds the intended file in the workspace and checks that it is a PDF.

In plain words
What is it for?
Use it to view a workspace PDF. To change, complete, or sign the document, use the separate annotate, fill-form, or sign commands.
Why use it?
It avoids searching for the file manually or opening it in another program. If the request is unclear, it lists available PDFs so you can choose one.

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.

Security

Grade A, and why

open 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 7d 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.

What it actually says

Open a PDF so it appears in the app's viewer panel.

Resolve which PDF is meant from: $ARGUMENTS

  1. Resolve the path: if the arguments name a file, find the real file in the workspace (glob for it if the path is partial; match case-insensitively). If no PDF is named, use the one most recently discussed or attached; if it's still ambiguous, list the workspace's PDFs and ask which one.
  2. Verify the file exists and is a .pdf.
  3. Surface it: write the file's workspace-relative path on its own line in your reply — that is what makes it appear as a clickable PDF artifact that opens in the viewer panel. The filename must be plain (no spaces or parentheses) to surface; if the name has spaces, make a plain-named copy (e.g. Lease (final).pdfLease-final.pdf), open the copy, and say why.

To act on the PDF instead of just viewing it, point the user at /annotate, /fill-form, or /sign.

Changes

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.
