What it does
Od Plugin Authoring is an agent skill from nexu-io/open-design. Guided scenario for creating an OpenDesign plugin folder that can be installed into My plugins.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `open-design.json`).
The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.
Example prompts
- “/od-plugin-authoring”
What it can do on your machine
Read from SKILL.md and the folder at commit d9dd6fe. 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
Od Plugin Authoring loads about 444 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 197 words of instructions outside code blocks.
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.

od-plugin-authoring (scenario)
Use this scenario when the user wants to create their own OpenDesign plugin.
Required outcome
Produce a folder named generated-plugin/ in the active project workspace.
At minimum, the folder must contain:
SKILL.mdwith frontmatter and clear agent instructions.open-design.jsonwith valid plugin metadata,od.kind, mode, task kind, capabilities, and inputs when needed.
Add examples/, assets/, or other supporting files only when they help the plugin be used or reviewed.
Authoring rules
- Follow
docs/plugins-spec.mdand the schema atdocs/schemas/open-design.plugin.v1.json. - Treat
SKILL.mdas the canonical behavior description.open-design.jsonshould describe how OpenDesign installs, applies, and presents that behavior. - Keep the generated plugin local-user friendly: it should not require marketplace publishing, enterprise trust setup, or private team catalog configuration.
- Choose a stable plugin id from the user's requested workflow. Use lowercase letters, numbers, dashes, underscores, or dots.
- Include a short readiness summary when finished:
- Files created.
- Whether the folder is ready to add to My plugins.
- Any validation or follow-up needed before install.
- A direct next-action prompt that offers: Add to My plugins, Publish repo, or OpenDesign PR.
