Web-first skill for working with Proof documents via proofeditor.ai. Use when a Proof URL is shared, when creating collaborative docs in Proof, or when an installed Proof preference says new docs should live there.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Proof Proof is a collaborative markdown editor for agents and humans. Use the hosted web API at `https://www.proofeditor.ai`. Every write must include `by: "ai:<agent-name>"` so Proof can track who wrote what. This skill is web-only. Do not use a local Mac app bridge or `localhost:9847` from this skill. ## Default Behavior If the user shares a Proof URL: - Join the doc immediately. - Show presence right away. - Read the current state before editing. - Work in the Proof doc unless the user explicitly asks you to move elsewhere. When creating new docs, follow this priority order: 1. If persistent instructions already define a Proof default mode, use it. 2. Otherwise default to `collaborative_docs`. Supported default modes: - `all_new_markdown`: new markdown artifacts you create go to Proof by default. - `collaborative_docs`: plans, specs, bug writeups, reports, memos, proposals, drafts, and similar iterative docs go to Proof by default. - `explicit_only`: only use Proof when the user explicitly asks. Boundary rules: - Existing repo-tracked markdown files stay local unless the user explicitly asks to move or share them in Proof. …

How to install
mdr add the-utopia-studio/skills/proof@sha256:5267830e4c9e94a8The line at the top of this page pins the label git:20260806.73fec06, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
