Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
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.
git clone --depth 1 https://github.com/daymade/claude-code-skillsWrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

daymade-skill 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 today.
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 it actually says
{
"name": "daymade-skill",
"description": "Daymade skills core suite. Bundles skill creation, quality review, real Claude/Codex Skill-surface governance, suite-migration reconciliation, and marketplace development tooling under one shared namespace. Skill governance separates canonical source, installed inventory, discovery policy, the fresh model-visible catalog, and router-resolved cold resources instead of optimizing cache counts; it preserves Claude's official versioned-cache lifecycle and verifies selected entries in the real host prompt. Skill verification separates risk classification from evaluation spend: bounded fixes use targeted checks, narrow behavior changes use sampled replays, and paired baselines, graders, benchmarks, or a viewer run only after explicit user authorization or a decision-bearing evidence plan plus opt-in; that authorization does not change the risk tier. Existing-skill edits retain an old-vs-new capability audit and content-bound packaging attestation so prompt compression cannot silently delete runtime contracts. When the official skill-creator plugin is also installed, skill-creator detects the coexistence and offers a consent-based, reversible SessionStart routing hook so the daymade edition wins deterministically; on machines without the official plugin nothing is ever installed.",

}What it installs
The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 485 tokens a session between them. Each is measured on its own page, and each can be installed alone.
What ships with it
1 file beside marketplace.json#daymade-skill 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.
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.

daymade-skill is a plugin published in the GitHub repository daymade/claude-code-skills (1,381 stars, last pushed today), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.
