canvas skillA

canvas is agent-read markdown (skill) from firzus/agent-skills: Renders a standalone analytical artifact — architecture review, audit, quantitative analysis, data-heavy report, comparison, timeline, progress dashboard — as a single self-contained HTML file opened beside the chat. Works in any environment (Codex, Claude Code, Cursor, generic agents). Use when the structured output IS the deliverable and benefits from visual layout, and whenever updating an existing canvas file..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add firzus/agent-skills/canvas@git:20260831.e35febb
Exact content
mdr add firzus/agent-skills/canvas@sha256:9595f4ec8a8fb575

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
