What it does

Cowart Image Gen is an agent skill from openvetta/open-vetta. Generate a bitmap for the Cowart canvas via Vetta generateimage, then insert or replace via Cowart MCP. Use when the user asks to create, fill, replace, or place an AI-generated image on a Cowart canvas.

Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Image generation. It works with Model Context Protocol. The repository describes itself as: Open-source, local-first AI agent for coding and real work. BYOK models, MCP, skills, plugins, workflows, and private knowledge bases. The licence is Apache-2.0.

When your agent uses it

  • The user asks to create
  • Place an AI-generated image on a Cowart canvas

Example prompts

  • “/cowart-image-gen”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read selection with MCP get_cowart_selection (projectDir = user workspace).
  2. If exactly one selected shape is an AI image holder (isAiImageHolder or meta.cowartAiImageHolder), use holder size (props.w / props.h) as…
  3. Call generate_image to produce the bitmap. Resolve the real local output path.
  4. Call MCP insert_cowart_image with projectDir and that image path

What it can do on your machine

Read from SKILL.md and the folder at commit b983179. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cowart Image Gen loads about 408 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 172 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~408

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Generate a bitmap for the Cowart canvas via Vetta generate_image, then insert or replace via Cowart MCP. Use when the user asks to create, fill, replace, or place an AI-generated image on a Cowart canvas.

Cowart Image Gen (Vetta)

Vetta image tools (required)

IntentTool
Brand-new image / fill AI image holder / invent a scenegenerate_image
Revise an existing image or annotation screenshotedit_image (use cowart-image-edit skill)

Do not use an imagegen skill or ad-hoc scripts. After the bitmap exists on disk, place it with Cowart MCP insert_cowart_image.

Preconditions

Cowart MCP tools should be available (plugin cowart-vetta enabled). Prefer opening the canvas first (open_cowart_canvas).

Workflow

  1. Read selection with MCP get_cowart_selection (projectDir = user workspace).

  2. If exactly one selected shape is an AI image holder (isAiImageHolder or meta.cowartAiImageHolder), use holder size (props.w / props.h) as the generation contract.

  3. Call generate_image to produce the bitmap. Resolve the real local output path.

  4. Call MCP insert_cowart_image with projectDir and that image path:

    • Holder selected → prefer replace the holder (replaceAiImageHolder: true).
    • Otherwise insert onto the current page (from view/canvas state).

Constraints

  • Pass user projectDir, not the plugin root.
  • Keep original holders only if the user asks to preserve slots.
  • Include target aspect ratio in the generate_image prompt when replacing a holder.
