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

proof-publisher scanned grade A with 1 finding 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 6d 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.

The opening of the file, as written. The whole thing — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Proof Publisher

Publish CKW markdown drafts to Proof — a collaborative document editor with character-level AI provenance tracking. Proof shows exactly what was written by AI vs. what was edited by humans, and gives teammates a Google-Docs-like interface for reviewing and commenting on drafts.

When to Use

  • User asks to "publish to Proof", "share on Proof", "send to Proof for review"
  • After /ckw:execute-phase completes and drafts are ready for human review
  • After /ckw:review-phase passes and you want reviewer comments visible inline
  • The /ckw:publish-proof command invokes this skill

Prerequisites

Check that curl is available (it should be on any macOS/Linux system):

which curl

If curl is not found:

curl is required for Proof publishing but isn't installed.
This is unusual — curl is pre-installed on macOS and most Linux distributions.

Stop here — do not attempt to publish without curl.

Proof API Reference

Proof works with both the hosted version (proofeditor.ai) and self-hosted instances. The API is identical — only the base URL changes.

Operation Method Endpoint Auth Required
Create document POST {base_url}/share/markdown None
Read state GET {base_url}/api/agent/{slug}/state x-share-token
Add comment POST {base_url}/api/agent/{slug}/ops x-share-token
Add suggestion POST {base_url}/api/agent/{slug}/ops x-share-token
Health check GET {base_url}/health None

Usage

This skill is invoked by the /ckw:publish-proof command or conversationally. Parse the user's intent:

Single file:

Publish drafts/executive-summary.md to Proof

With review comments:

Publish drafts/executive-summary.md to Proof with review comments

Check status of existing doc:

What's the current state of the Proof doc for executive-summary?
