Description
plan-canvas is an agent skill from the ECC collection by affaan-m, listed on skills.sh. It opens a plan or an HTML artifact in a local browser canvas, where the person reviews the exact element they mean, annotates it, chats about it, and then gives an Approve plan or Request changes verdict. The agent writes the artifact and blocks on a single command-line call that returns the person's feedback as JSON. This replaces a typed yes or proceed at the plan confirmation step in ECC's /plan workflow. It works with a plan file written by /plan and with any local markdown or HTML artifact, such as designs, comparisons and reports. The skill is adapted from the lavish-axi project and rebuilt for ECC with no extra dependencies. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows a Snyk warning, with Gen Agent Trust Hub and Socket passing.…
