About the project

Brave Search API Skills is a collection of agent skills that gives AI coding agents access to the Brave Search API. It is intended for agents such as Claude Code, Cursor, GitHub Copilot, Codex, Gemini CLI, and other tools supporting the Agent Skills standard. The catalogue add-ons are the project's own skills and configuration guidance for using Brave Search.

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.

Security

Grade C, and why

bx scanned grade C with 2 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 13d 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.

# or: export BRAVE_SEARCH_API_KEY=YOUR_KEY

# Search (default = bx context "query")
bx "your search query"

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.
