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.
/plugin marketplace add Jimmynycu/token-efficiencynpx agentmods add plugins/jimmynycu/token-efficiency/token-efficiency-coachgit clone --depth 1 https://github.com/Jimmynycu/token-efficiencyGrade A, and why
token-efficiency-coach 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 2d 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.

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.

Personal skill collection. Skills are invoked as superb: . craft turns a vague product idea into a decision-rich CRAFT.md brief — it questions, challenges and records, and deliberately stops short of planning. pipeline takes a settled idea to a finished branch, composing the superpowers skills with a zero-assumpt.
