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.

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 | $0.00096 | $0.00726 |
| Opus 5 | $0.00048 | $0.00363 |
| Sonnet 5 | $0.00019 | $0.00145 |
| Haiku 4.5 | $0.00010 | $0.00073 |
Grade A, and why
start scanned grade A with 0 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 4d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
start — diagnose project state and recommend the next skill
When to trigger
- Right after
omit-design init. - The user says something open-ended: "what now?", "I want to make something", "where do I begin?".
- The user explicitly invokes
/start.
Do NOT trigger when the user already named a concrete action ("add a list page" → use new-design directly).
Decision tree
Check 1 — is this an omit-design project?
- Does
package.jsondeclare@omit-design/preset-mobileas a dep? - Does
design/exist? - If either is no → tell the user this isn't an omit-design project, suggest
npx @omit-design/cli init <name>. Stop.
Check 2 — is design/ essentially empty?
- Count
.tsxfiles underdesign/**. - If only
welcome.tsx(or 0 files) → recommendnew-design. The user just scaffolded; first action is making a real page.
Check 3 — does the project pass npm run lint?
- Run
omit-design lint --json(silent) to inspect violations. - If violations > 0 → recommend
audit-designin repair mode. Quote the top 3 most-violated files. - If lint passes → continue to Check 4.
Check 4 — pattern diversity
- Inspect
// @pattern:headers acrossdesign/**/*.tsx. - If only 1–2 distinct patterns used and the project has > 3 pages → suggest
add-patternif the user describes a need that doesn't fit the 8 built-ins; otherwise suggestnew-designto broaden coverage. - If everything looks healthy → list the design pages with their patterns and ask the user what they want to do next.
Output format
Always end with a single concrete recommendation, formatted as:
→ Recommended next step: /<skill-name>
Why: <one-line reason from the check that fired>
To proceed: <one-line concrete invocation, e.g. "tell me the PRD for the next page">
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.
- 4d ago First seen · 58 lines · 96 tokens per session scan A 985318a67369
start is a skill published in the GitHub repository leefanv/omit-design (54 stars, last pushed 3mo ago), licensed MIT. It adds 96 tokens to every session and 726 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
