Zugzwang: Skill for Claude Code

.agents/skills/implement-knowledge-packet/SKILL.md

implement-knowledge-packet is a skill for Claude Code, Codex from maelrx/Zugzwang. It costs 36 tokens per session (265 once invoked), scanned A, original, GPL-3.0.

A workflow for creating static expert knowledge packets with source details, safety controls, text matching, information-leak checks, and K-class labels. These packets provide prepared knowledge before dynamic retrieval-augmented generation, or RAG, is available.

In plain words
What is it for?
Use it to author or implement KnowledgePacket support, including provenance, controls, token matching, leakage checks, and K-class assignment.
Why use it?
It helps make expert knowledge traceable and checks that it is classified and handled safely before the system can fetch knowledge dynamically.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is maelrx/Zugzwang's own configuration. It tells Claude Code and Codex how to work on Zugzwang itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Zugzwang configures →

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

implement-knowledge-packet 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 2mo 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.
