oh-my-agent is a harness for checking whether coding agents actually completed their work by verifying tests, required artifacts, independent reviews, and recorded decisions. It is used across multiple agent runtimes to make workflow results auditable instead of relying on an agent's own report. The catalogue add-ons provide parts of its skills, agents, hooks, MCP integrations, instructions, 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.

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 | $0.00058 | $0.03192 |
| Opus 5 | $0.00029 | $0.01596 |
| Sonnet 5 | $0.00012 | $0.00638 |
| Haiku 4.5 | $0.00006 | $0.00319 |
Grade A, and why
oma-design 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 today.
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.

Scheduling
Goal
Design specialist that defines, creates, and validates project design systems. DESIGN.md is the central artifact; all design work revolves around it.
Intent signature
- User asks for design system,
DESIGN.md, visual direction, typography, color, motion, accessibility, anti-pattern review, or component guidance. - User needs design decisions before frontend implementation or wants UI quality audited from a design perspective.
When to use
- Defining or revising a project design system
- Creating or auditing
DESIGN.md - Selecting typography, color, layout, motion, or component direction
- Reviewing UI work for responsive behavior, accessibility, and visual quality
- Redesigning an existing site or app (preserve vs overhaul modes)
- Using optional vendor inspiration from Stitch MCP or getdesign
When NOT to use
- Implementing frontend components or application UI -> use
oma-frontend - Planning product scope or task breakdown -> use
oma-pm - Backend, database, infrastructure, or mobile implementation -> use the relevant specialist skill
- General quality/security review outside visual, interaction, and accessibility concerns -> use
oma-qa
Expected inputs
- Product, brand, audience, platform, and UI/design problem
- Existing
.design-context.md,DESIGN.md, screenshots, references, or component constraints - Accessibility, responsive, language, and implementation constraints
Expected outputs
- Design direction, revised
DESIGN.md, audit findings, component guidance, or handoff notes - Responsive-first, WCAG-aware design recommendations
- Optional vendor seed attribution when getdesign is used
outputs:
- name: design-doc
description: Updated DESIGN.md when the run materially advances the design system
artifact: "DESIGN.md"
required: false
- name: design-context
description: Refreshed .design-context.md snapshot when a discovery pass runs
artifact: ".design-context.md"
required: false

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.

oma-design is a skill published in the GitHub repository first-fluke/oh-my-agent (1,278 stars, last pushed today), licensed MIT. It adds 58 tokens to every session and 3,192 once invoked, about $0.0003 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.
