Configuration Reference

This is the complete configuration reference. All fields are optional — unset fields use their compiled defaults. The file lives at ~/.edgecrab/config.yaml.

Tip

Run edgecrab config show to print your active resolved configuration (after env override merging).

Pro Tips

• Use edgecrab config show to see the fully-merged config (YAML + env overrides) without editing files.
• Use edgecrab config set model.max_iterations 150 for large refactors instead of editing the YAML manually.
• EDGECRAB_* env vars always override config.yaml: perfect for CI — set env vars in your pipeline and never touch the baked-in config file.
• compression.threshold: 0.35 triggers summarisation earlier so context windows stay comfortable for models with smaller windows (32K-class local models).
• security.managed_mode: true locks config writes at runtime — the agent cannot change its own settings (useful in production gateways).

FAQ

Where does the config file go? ~/.edgecrab/config.yaml. Override with --config <path> or EDGECRAB_HOME=<dir>.

What happens if I have a typo in config.yaml? EdgeCrab reports a YAML parse error and exits. Run edgecrab doctor to diagnose. Use edgecrab config show to preview the merged config before a long session.

Can I have multiple config files (e.g. work vs. personal)? Yes — use Profiles (edgecrab profile create work) or pass --config ~/work-config.yaml per invocation.

How do I set a custom base_url for a non-OpenAI provider? In config.yaml:

model:
  default: "my-provider/my-model"
  base_url: "https://api.myprovider.com/v1"
  api_key_env: "MY_PROVIDER_API_KEY"

Does changing model.max_iterations affect memory or cost? Higher max_iterations allows longer tool-call chains, which can increase cost and latency on large tasks. It does not affect memory. The agent still stops early if the task completes before the limit.
