Z88dk Tooling

Q: What is a Claude Code skill and how does the Z88dk Tooling skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Z88dk Tooling is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

How to use z88dk host tools to measure, profile, and diagnose 8085 (and related) code in the z88dk tree: z88dk-ticks timing and debugger, hotspots, map/nm/disassembly, suite tests, A/B library swaps, z88dk-copt peephole rules (and what they mean for hand-written library asm vs compiler output), and common measurement pitfalls. Use when optimising library asm, writing or reviewing sccz80/copt-shaped codegen, explaining benchmark deltas, verifying regressions, running +test -clib=8085, or the user runs /z88dk-tooling.

From the source SKILL.md

This skill covers host tools used with z88dk when writing or optimising 8085 (and portable 8080/gbz80) library code. Opcode and coding rules stay in opcode-reference and extended-usage; here the focus is how to prove what is slow, what changed, and what is correct — plus how z88dk-copt shapes compiler output and what library authors must do by hand.

What this skill does

Z88dk Tooling is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/z88dk-tooling/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when optimising library asm, writing or reviewing sccz80/copt-shaped codegen, explaining benchmark deltas, verifying regressions, running +test -clib=8085, or the user runs /z88dk-tooling.

Who uses this skill

The Z88dk Tooling Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
