A guide for writing Zig code and working with Zig project files. Zig is a systems programming language, and build.zig and build.zig.zon configure its builds and packages.

Use it for .zig files, build configuration, package manifests, cross-compilation, and C interoperability.

It provides task-specific guidance when the agent needs to understand Zig syntax, builds, or related system-level features.

zig — Skill for Claude Code by dmaynor

Install

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.

Any agent

npx skills add dmaynor/dmaynor-skills-marketplace --skill zig

Clone the repo

git clone --depth 1 https://github.com/dmaynor/dmaynor-skills-marketplace

Made for: Claude Code.

Or install zig, the plugin that ships this one along with the rest of its 1 skill.

Per session 99 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin unknown No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00099	$0.02153
Opus 5	$0.00049	$0.01077
Sonnet 5	$0.00020	$0.00431
Haiku 4.5	$0.00010	$0.00215

Security

Grade A, and why

zig 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 yesterday.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/analyze_code.py, scripts/scaffold_project.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

zig is a skill published in the GitHub repository dmaynor/dmaynor-skills-marketplace (5 stars, last pushed yesterday), with no licence file. It adds 99 tokens to every session and 2,153 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
