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.

peer-message 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": "peer-message",
"description": "Discover, message, and coordinate local AI-agent sessions across Claude Code profiles and OpenAI Codex threads. Use whenever the user asks to contact another terminal/session/agent, says 给另一个 session 发消息 / 问一下另一个窗口 / 广播给所有 agent / agent communication protocol, needs Claude and Codex to coordinate work, or needs a hook/script to post into a running session. Routes Claude targets through official peer tools when available and through the same authenticated UDS inbox protocol as a fallback; routes Codex targets through the installed `codex queue` command. Supports explicit cross-provider broadcasts and receiver-side delivery verification. Also use when peer messages keep getting held for manual approval, or when an unattended endpoint needs `crossSessionInbound` accept setup. Also applies when an inbound peer message asserts something about your session or shared state, or asks you to pause/release something. Not for spawning agents, moving full conversation context, or treating a peer message as user approval.",

}What ships with it
1 file beside marketplace.json#peer-message 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.

peer-message 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.
