OpenDesign is an open-source, local-first desktop app that lets coding agents create prototypes, dashboards, slide decks, images, video, and design systems as exportable files. It is used by people working with agent runtimes such as Claude Code, Codex, Cursor, and DeepSeek Harness. The catalogue add-ons extend the OpenDesign workflow with skills, instructions, commands, and plugins.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 23 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00308 |
| Opus 5.5 | $0.00010 | $0.00123 |
| Sonnet 5.5 | $0.00005 | $0.00062 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade B, and why
od-plugin-publish-github scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
`curl -sS -X POST "$OD_DAEMON_URL/api/projects/$OD_PROJECT_ID/plugins/publish-github" -H 'content-type: application/json' -d '{"path":"<plugin_context_path>"}'` Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says
Publish Plugin to GitHub
Use this workflow when the active project contains a copied plugin folder and the user wants it published as a new public GitHub repository.
Workflow
- Read the active plugin inputs.
plugin_context_pathis the copied plugin folder relative to the project working directory. - Inspect
open-design.json,SKILL.md, and any compatibility metadata in the copied folder. - Call the local daemon endpoint instead of hand-rolling GitHub commands:
curl -sS -X POST "$OD_DAEMON_URL/api/projects/$OD_PROJECT_ID/plugins/publish-github" -H 'content-type: application/json' -d '{"path":"<plugin_context_path>"}' - Read the JSON response. If
okis true, report the final repository URL and any useful log/validation summary. - If the endpoint fails, report its
message,code, and useful log lines. When authentication is missing, tell the user to rungh auth login --hostname github.com.
Prefer the manifest name as the repository slug. If that repository already exists, choose the next clear slug and mention the rename.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
