A command for placing a visible signature block on a PDF copy, using a typed name and date or a PNG signature image. It does not create a legally verifiable cryptographic signature.

In plain words
What is it for?

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

sign 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 10d 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

Sign a PDF — stamp a visible signature block (typed name + date, or a PNG signature image) that the user reviews in the in-app PDF viewer. The original file is never modified. This is a visible stamp, not a cryptographic signature.

Load and follow the pdf-tools skill, then carry out this request:

$ARGUMENTS

Reminders from the skill:

  • The signer's name is required — if the arguments don't say who signs, ask; never sign with a guessed name. --date defaults to today.
  • inspect the PDF first; the default placement is the bottom-right of the LAST page — pass --page/--x/--y (points, origin bottom-left) to hit an actual signature line instead.
  • If the user provided a signature image, pass it with --image (PNG only).
  • The sign subcommand writes <name>.signed.pdf next to the source.
  • End your reply with the output name the tool returns on its own line so the signed copy surfaces as a clickable PDF artifact in the panel.

If no PDF is named in the arguments, ask which document to sign first.

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.
