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.

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 | $0.00097 | $0.08913 |
| Opus 5.5 | $0.00039 | $0.03565 |
| Sonnet 5.5 | $0.00019 | $0.01783 |
| Haiku 4.5 | $0.00010 | $0.00891 |
Grade C, and why
agent-web-search-setup scanned grade C with 3 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 16d 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.

Agent Web Search Setup
A model backend that cannot search is not the same as a model that searched and found nothing, but from inside the conversation the two look identical. This skill turns the first into the second, on whichever agent is in front of you. It configures the agent's tools; it is not itself a search engine, so nothing here answers a query directly — the proof of done is the agent's own session calling a real tool.
What actually breaks
Anthropic's web_search and web_fetch are server tools: the API runs them
during the request and splices results into the same response. OpenAI's Responses
API web_search works the same way. The client only ever declares the tool.
A reseller that proxies to another cloud cannot execute those. Anthropic's own documentation states that web fetch is unavailable on Amazon Bedrock and Google Cloud; search was measured failing the same way on both. What comes back is not an error. It is an empty shell, so the model concludes the topic does not exist and says so with total confidence. That is the whole bug, and it is why users report their agent has "gotten stupid" rather than reporting a broken tool.
Three things follow, each of which cost real time to establish:
- Switching models does not help. One reseller was measured routing four model names to three different backends; none produced a working search.
web_fetchbreaks with it. Fixing only search moves the failure from "I found nothing" to "I found links but cannot open them."- Installing an alternative is not enough on its own. With the dead tool still on the menu, a model made 21 web-search calls and 0 calls to an installed alternative whose description said the built-in was broken. Built-in tools win head-to-head. The dead tool has to be removed, or nothing else you do matters.
1. Prove it, on this machine
Do not take the user's word for which tool is broken, and do not take yours.
<skill> below is the directory holding this SKILL.md — substitute the real
path. If it is somehow not known, find ~ -type d -name agent-web-search-setup
locates it.
What ships with it
3 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.
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.

agent-web-search-setup is a skill published in the GitHub repository daymade/claude-code-skills (1,516 stars, last pushed yesterday), licensed MIT. It adds 97 tokens to every session and 8,913 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it C with 3 findings (reads agent configuration directories, unrestricted tool access, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-15.
