v0.4.54

fast-agent 0.4.54

Sonnet 4.6 and Web Search/Web Fetch features

Support for claude-sonnet-46, as well as Web Search and Fetch features (all supported models). Enable with ?web_search=on&web_fetch=on.

NB The older web tools appear to perform better, I will continue testing and revert/fix as needed.

Agent Card MCP enhancements / Smart Agent improvements.

Specify url, npx or uvx MCP connections directly from the Agent Card:

mcp_connect:
  - target: "https://hf.co/mcp"
    name: "hf_hub"
  - target: "npx @modelcontextprotocol/server-everything"
    name: "everything"

Smart Agent instructions can be added to prompts with:

{{internal:smart_prompt}} for the default smart agent prompt, {{internal:smart_agent_cards}} for the description section. Read more at https://fast-agent.ai/agents/instructions/#template-variables for other new template vars.

Web Socket Improvements

Improved Web Socket handling for codexplan models.
