 # synu
 
-A universal wrapper for AI agents that tracks quota usage for [Synthetic](https://synthetic.new) API calls.
+Universal wrapper for LLM agents that tracks
+[Synthetic](https://synthetic.new) usage and interactively preconfigures
+supported agents for currently-available models (so you can try a new
+one as soon as they support it, without waiting for the agent itself to
+gain support!)
 
 ## Requirements
 
 - Fish
 - `curl` - for API requests
 - `jq` - for JSON parsing
-- `gum` - for interactive model selection ([install](https://github.com/charmbracelet/gum))
-- `SYNTHETIC_API_KEY` environment variable (for quota tracking with Synthetic)

-The quota tracking requires the `SYNTHETIC_API_KEY` environment variable. Without it, `synu` will show a warning and skip quota tracking, but still attempt to run the agent.

-### Adding Support for New Agents
-
-Agent definitions are stored in `functions/_synu_agents/`. Each agent file can define:
-
-- `_synu_agent_<name>_flags` - Returns argparse flag specification
-- `_synu_agent_<name>_configure` - Sets environment variables/state before execution
-- `_synu_agent_<name>_args` - Returns CLI arguments to inject
-- `_synu_agent_<name>_env_vars` - Lists environment variables to clean up
-- `_synu_agent_<name>_interactive` - Implements interactive model selection
-
-Agents without definitions work as passthrough with quota tracking.

-See `AGENTS.md` for detailed implementation guidance.
