Greptile SummaryThis PR hardens local-agent configuration and daemon behavior, adds provider environment overlays for OpenCode and Pi, preserves empty daemon responses, and unifies executable validation.
Confidence Score: 4/5The PR is not yet safe to merge because independent DevSpace daemons can contend for the newly fixed OpenCode server port. OpenCode runtime creation now always requests port 4096 even though daemon instances are independently scoped by state directory, so a valid second daemon or an unrelated listener can make the provider unavailable. Files Needing Attention: src/local-agent-opencode.ts
|
| Filename | Overview |
|---|---|
| src/local-agent-opencode.ts | Replaces SDK-managed OpenCode startup with an environment-aware managed process, but hard-codes a host-global listener port. |
| src/local-agent-client.ts | Allows get, list, and wait requests to observe active turns on a configuration-stale daemon while retaining replacement rules for new work. |
| src/local-agent-pi.ts | Scopes configured Pi environment overrides to provider authentication resolution and session creation. |
| src/local-agent-pi-sandbox.ts | Applies Pi provider environment overrides to both unrestricted and sandboxed Bash executions. |
| src/local-agent-config.ts | Splits command-capable and embedded-provider validation while enabling environment configuration for every provider. |
| src/local-agent-daemon-protocol.ts | Preserves empty and whitespace-only latest responses during daemon record decoding. |
| src/local-agent-command.ts | Centralizes executable-file validation for provider discovery and runtime command resolution. |
| schema/v1/devspace.schema.json | Aligns generated provider schemas with runtime command and environment support. |

In `@src/local-agent-opencode.ts`:
- Line 183: Update the startup flow around allocateOpencodePort and the opencode
serve launch to retry a bounded number of times when startup fails specifically
because the allocated address is already in use. Reallocate a fresh port for
each attempt, preserve normal propagation for other startup failures, and only
continue once OpenCode binds successfully.
