OpenCode repeatedly retries after a mid-tool provider disconnect #32286

Description

If the provider connection closes after a streamed tool call has been delivered but before a clean message completion, OpenCode repeatedly retries the provider interaction instead of failing boundedly.

In the latest local verification run, OpenCode made 588 provider requests and saw 588 mid-stream connection closures before the reproducer timeout killed the process.

Plugins

None. The standalone reproducer sets OPENCODE_DISABLE_DEFAULT_PLUGINS=1.

OpenCode version

1.17.4

Steps to reproduce

Prerequisites: Docker, Python 3, and the GitHub CLI (gh) for the clone command below. The linked reproducer is self-contained and uses only Python standard-library modules plus Docker. It builds [email protected] from the public npm package, starts a local mock provider, and runs the CLI in an isolated workspace. The Docker run is limited to 2 CPUs and 4 GiB RAM by default.

gh gist clone 5861579c2e83fed87126293bf76bbbcf opencode-post-tool-transient-disconnect-reproducer
cd opencode-post-tool-transient-disconnect-reproducer
python3 opencode-post-tool-transient-disconnect.reproduce.py

To reuse an already-built local image:

python3 opencode-post-tool-transient-disconnect.reproduce.py --skip-build

Expected successful reproduction output includes:

provider_requests=588
