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.

llm-eval-harness scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

"description": "Test/evaluate any LLM behind an OpenAI- or Anthropic-compatible endpoint: availability (max_tokens-aware), request fidelity (does system prompt/tools/history REACH the model, or does the gateway silently drop it), speed (TTFT+tok/s), concurrency (before a workshop), Anthropic protocol compliance, quality regression, vendor bug reports, deployment gates, resident canaries. Reach for this BEFORE hand-rolling a curl loop against any LLM endpoint — that instinct is the trap: it skips the N=10 sampling, Connection:close, and env-var key handling this bakes in. Use when someone tests/benchmarks/测评/压测 a model/endpoint, onboards a provider, decides whether to switch or temporarily fail over to an alternate channel (e.g. outage or quota exhaustion), writes a supported-models list, debugs \"model ignores system prompt\", or verifies a tok/s claim. Triggers on \"benchmark this model\", \"测一下这个模型/渠道/API\", \"接入新模型先测一下\", \"system prompt 不生效\", \"这个渠道能不能用/稳不稳\", \"临时切换过去顶一阵子\" — even without \"eval\", even wrapped in business narrative.",

}What ships with it
1 file beside marketplace.json#llm-eval-harness 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.

llm-eval-harness 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 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other plugins, from other repositories
evals
LLM evaluation methodology and eval-suite design, distilled from Anthropic's official evaluation guidance — a knowledge router over success criteria, eval design, and grading methods (/evals:methodology), plus an action skill that interviews for measurable success criteria and scaffolds a graded eval suite for an LLM…
rust-intel
Defense against LLM Rust failure modes: 59 categories of bugs that survive rustc, clippy, and cargo test — async cancellation, unsafe/FFI, concurrency, crypto, supply-chain, tests-that-pass-by-luck, semantic conformance, and systemic performance cost. Ships the rust-intel skill plus /rust-intel:audit, /rust-intel:fix.
evals-skills
Skills for building LLM evaluations: pipeline audit, error analysis, synthetic data generation, LLM-as-Judge design, evaluator validation, RAG evaluation, and annotation interfaces.
nextjs
Official Next.js skills: adopt and optimize Cache Components, adopt Partial Prefetching, and verify runtime behavior against a running dev server.
