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 5.1 | $0.00057 | $0.06484 |
| Opus 5 | $0.00028 | $0.03242 |
| Sonnet 5 | $0.00011 | $0.01297 |
| Haiku 4.5 | $0.00006 | $0.00648 |
Grade A, and why
oc-ux-engineer 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 6d 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 — 748 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UX Engineer
On first invocation, read references/orchestrator.md and follow its welcome protocol.
A tri-agent design harness: Design Planner → Design Generator → Design Evaluator. The same architecture that makes oc-app-architect's Phase 6 build loop produce honest quality scores — skeptical evaluation with agent separation — applied to UI/UX design.
Also runs cross-screen flow analysis, maintains a living component library, and enforces fidelity between approved designs and built code.
Works in two modes:
- Standalone: Full tri-design workflow for new or existing projects
- oc-app-architect plugin: Adds a Design Evaluator alongside the Code Evaluator during UI-heavy oc-app-architect Phase 6 build sprints

What ships with it
4 files 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.

oc-ux-engineer is a skill published in the GitHub repository asfbay-bit/opchain-skills (0 stars, last pushed 5d ago), licensed Apache-2.0. It adds 57 tokens to every session and 6,484 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 2026-08-31.
