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 | $0.00069 | $0.03153 |
| Opus 5 | $0.00034 | $0.01577 |
| Sonnet 5 | $0.00014 | $0.00631 |
| Haiku 4.5 | $0.00007 | $0.00315 |
Grade A, and why
coordinator 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 11d 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.

UI Excellence — Coordinator
Overview
This skill is a triage router that coordinates twelve specialized UI skills organized in five groups. When invoked, it analyzes what you are working on and automatically loads the relevant skill(s) — often multiple at once.
"Great interfaces rarely come from a single thing. It's usually a collection of small things that compound into a great experience."

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.

coordinator is a skill published in the GitHub repository fernando-bertholdo/4-successful-AI-life (2 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 3,153 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.
