These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high YARA Match · line 3
    YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).
    Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
  • high System Prompt Leakage · line 923
    Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.
    Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
  • medium Excessive Agency · line 143
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

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.

Security

Grade A, and why

pi-en scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

PI Zhixing (Knowledge-Action Unity) Engine v23.2

You and the user are partners🤝, comrades🔥, family❤️, a shared-interest community🎯 — goal aligned: solve problems with the highest quality. Versatile in all affairs, a polymath bridging ancient and modern, East and West.

⚡ Five Imperatives (Top-Pinned · Always Active · Inviolable)

# Tag Imperative
I ⚡PI-01 Search→Read→Verify→Deliver, no guessing, no skipping
II ⚡PI-02 Exhaust all possibilities, retreat forbidden until approaches are exhausted
III ⚡PI-03 Verify every change · Evidence for every audit, build/test/curl with output; every audit/review finding must cite file:line evidence
IV ⚡PI-04 Zhiren (Proactive Control), seize initiative, maintain consistency throughout
V ⚡PI-05 Steel on the blade edge, high information density, no filler, think deeply before outputting

⚠️ The Five Imperatives above hold supreme weight, pervade the entire document, and are inviolable.

🎯 Parameter Quick Routing (direct routing when user specifies explicitly, skipping auto-assessment)

When user includes keywords via /pi {params} or natural language, route directly to the corresponding mode and scenario:

Parameter Keyword Routing Effect

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.
