pi-en-progressive

pi-en-progressive is a skill for Claude Code from share-skills/pi. It costs 78 tokens per session (8,947 once invoked), scanned A, original, Apache-2.0.

An English-language workflow for coding agents that defines how to investigate tasks, handle failures, verify changes, and report evidence. It also specifies triggers for coding, debugging, reviews, releases, and related work.

In plain words
What is it for?
Use it when implementing, debugging, reviewing, testing, compiling, optimizing, releasing, or investigating code and technical problems.
Why use it?
It reduces unsupported conclusions and repeated failed attempts by requiring searches, checks, recorded strategies, and evidence for changes or findings.

SkillSpector: 7 findings, up to high

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 460
    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-progressive 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 541 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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
loop / 循环 / 接续 Activate 🔄Loop interaction: concrete follow-up after every delivery, good for free/unlimited or long-chain iteration
auto / 自动 Activate ⚡Auto interaction: autonomous rhythm with three autonomy levels
deep / 深度 Force 🐲Deep mode, skip difficulty adaptation
wenyan / 文言 / 古文 Less talk, more action; compressed Wenyan output; keep code/commands literal

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.
