OpenCode Provider

When To Use This Provider

Use OpenCode when your CI environment already installs and authenticates an OpenCode CLI that can run as the selected DiffPal provider.

Prerequisites

• A DiffPal config committed at .config/diffpal/config.yaml.
• An OpenCode CLI available in the CI job.
• Provider credentials configured with OpenCode's own authentication flow.

Installation

Install OpenCode in CI using the installation method you use for OpenCode in that environment. Pin the OpenCode package or source revision in your CI setup the same way you pin other provider CLIs.

Authentication In CI

Authenticate OpenCode before running DiffPal. Store any OpenCode credentials in protected CI secrets and pass them to the OpenCode CLI using its supported authentication mechanism.

Do not expose OpenCode credentials to untrusted fork jobs. Keep the credentialed review job limited to trusted branches, same-repository pull requests, or maintainer-approved jobs that do not execute fork-controlled code.

Minimal Verified Configuration

Use examples/configs/opencode-acp/config.yaml.

The provider selection is:

runtime:
  providers:
    opencode-acp:
      type: opencode_acp
      opencode_acp:
        model: opencode/big-pickle

diffpal:
  provider: opencode-acp

How To Test Provider Connectivity

Validate the local runtime first:

diffpal doctor --profile ci --mode local

Then run a provider-backed smoke review on a trusted branch:

diffpal --profile ci review local \
  --base origin/main \
  --head HEAD \
  --feedback summary \
  --out .artifacts/diffpal/findings.json

Expected Result

The smoke review should complete, write .artifacts/diffpal/findings.json, and print a Markdown summary to stdout.

Security Considerations

DiffPal does not manage OpenCode accounts, credentials, models, or sandbox settings. Keep OpenCode credentials in protected CI secrets and run secret-backed review only in trusted branches, same-repository pull requests, or maintainer-approved jobs that do not execute untrusted code with secrets.

Common Failures

• The OpenCode CLI is not installed before DiffPal runs.
• OpenCode authentication is missing from the trusted CI job.
• The configured model is not available to the authenticated OpenCode account.
• The selected diffpal.provider does not match the opencode-acp provider entry.
