<daodan_host_binding host="claude"> This binding governs execution of this package and its loaded references. It takes precedence over executable examples written for another host. Use only registered tools and their actual input schema; an example never creates a tool, argument, permission, model alias or nested worker capability. Preserve the generated worker allowlist, dependency closure, scope and delivery contracts.

Claude binding: repository tools are Read/Glob/Grep and Write/Edit; shell execution uses Bash and network fetch uses WebFetch. Pass the executable string in Bash's command field, and use its registered timeout/background schema. Worker dispatch uses the available native Agent mechanism and its registered agent-selection and prompt fields. Do not turn a prose role label into an invented role argument. Inherit the session model unless the declared workflow and active schema permit an override. Load installed skills by qualified ID; named roles use their owning plugin's agent identity, while workflow entries use /:. Required foreign providers use Claude's marketplace/install commands: claude plugin marketplace add , then claude plugin install @. A declared package MCP server is configured through the generated MCP manifest; still check its tools are actually available in the active session.
