fix: convert OpenCode model format to CLI slash format by stefandevo · Pull Request #605 · AutoMaker-Org/automaker

stefandevo · 2026-01-19T20:07:06Z

Summary

Fixes OpenCode CLI model format conversion that was broken after commit 4b0d1399 changed model IDs from slash format (opencode/model) to prefix format (opencode-model).

Problem

After selecting an OpenCode model (e.g., "Big Pickle"), the CLI would fail with:

ProviderModelNotFoundError
  providerID: "big-pickle"
  modelID: ""

The CLI was receiving --model big-pickle instead of --model opencode/big-pickle.

Root Cause

Commit 4b0d1399 ("feat: implement cursor model migration and enhance auto mode functionality") changed OpenCode model IDs from opencode/big-pickle to opencode-big-pickle
The buildCliArgs() method in opencode-provider.ts was not updated to convert the new format back to CLI format
simple-query-service.ts calls stripProviderPrefix() which strips opencode- prefix
Result: bare model name big-pickle was passed to CLI, which interpreted it as a provider ID

Solution

Updated buildCliArgs() to properly convert model formats:

Input (after prefix strip)	CLI Argument	Reason
`big-pickle`	`opencode/big-pickle`	Bare name → prepend `opencode/`
`glm-4.7-free`	`opencode/glm-4.7-free`	Bare name → prepend `opencode/`
`github-copilot/gpt-4o`	`github-copilot/gpt-4o`	Has slash → pass through
`google/gemini-2.5-pro`	`google/gemini-2.5-pro`	Has slash → pass through

This handles all 100+ dynamic provider models correctly - the slash detection ensures dynamic models pass through unchanged.

Testing

Server unit tests pass (npm run test:server)
Manual test: Select OpenCode model, run feature, verify no error

Files Changed

apps/server/src/providers/opencode-provider.ts - Updated buildCliArgs() method

Summary by CodeRabbit

Bug Fixes
- Improved model name handling so different model naming formats and prefixes (including provider-qualified names) are consistently translated for CLI use, preventing mismatches when specifying models.

_{✏️ Tip: You can customize this high-level summary in your review settings.}

The OpenCode CLI expects models in provider/model format (e.g., opencode/big-pickle), but after commit 4b0d139 changed model IDs from slash format to prefix format, the buildCliArgs() method was not updated to convert back to CLI format. Root cause: - Commit 4b0d139 changed OpenCode model IDs from opencode/model to opencode-model - The old code used stripProviderPrefix() which just removed the prefix - This resulted in bare model names (e.g., "big-pickle") being passed to CLI - CLI interpreted "big-pickle" as a provider ID, causing ProviderModelNotFoundError Fix: - Updated buildCliArgs() to properly convert model formats for CLI - Bare model names (after prefix strip) now get opencode/ prepended - Models with slashes (dynamic providers) pass through unchanged Model conversion examples: - opencode-big-pickle → (stripped to) big-pickle → opencode/big-pickle - opencode-github-copilot/gpt-4o → (stripped to) github-copilot/gpt-4o → github-copilot/gpt-4o - google/gemini-2.5-pro → google/gemini-2.5-pro (unchanged)

Summary of Changes

Hello @stefandevo, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical bug in the OpenCode integration where model selection was failing due to an incompatibility in model ID formats between the application's internal representation and the OpenCode CLI's expectations. The changes introduce robust logic to correctly translate model identifiers, ensuring that all OpenCode models are passed to the CLI in the required slash-separated format, thereby restoring proper functionality.

Highlights

Fixes OpenCode CLI Model Format Conversion: This pull request resolves an issue where the OpenCode CLI failed to correctly process model IDs due to a format mismatch. Previously, a commit changed model IDs from a slash format (e.g., opencode/model) to a prefix format (e.g., opencode-model), but the CLI argument builder was not updated to reflect this change.
Incorrect Model ID Handling: The buildCliArgs() method in opencode-provider.ts was not updated to convert the new opencode- prefixed model IDs back to the opencode/ slash format expected by the CLI. This resulted in bare model names being passed, leading to ProviderModelNotFoundError.
Updated Model ID Conversion Logic: The buildCliArgs() method has been enhanced to correctly convert model IDs. It now strips the opencode- prefix and prepends opencode/ for bare OpenCode models, while preserving models already in provider/model slash format (e.g., github-copilot/gpt-4o).
Removal of stripProviderPrefix: The stripProviderPrefix utility function is no longer needed for OpenCode model ID processing within opencode-provider.ts and has been removed.

📝 Walkthrough

Walkthrough

OpencodeProvider's model formatting in buildCliArgs was changed: instead of stripping a provider prefix, the code now converts input model names into CLI-ready --model values by handling opencode-prefixed names, provider/model forms, bare names, and already provider-qualified names with specific rules.

Changes

Cohort / File(s)	Summary
OpencodeProvider Model Translation `apps/server/src/providers/opencode-provider.ts`	Removed `stripProviderPrefix` import and replaced prior stripping logic with conversion rules: if model starts with `opencode-`, drop prefix then if it contains `/` use as-is, otherwise prefix with `opencode/`; if model already contains `/` use directly; pass resulting `cliModel` to `--model`.

🐰 A model once peeled, now smartly dressed,
I hop and tweak each name with zest,
Slashes kept and prefixes sown,
Opencode paths find their own home.

Code Review

This pull request addresses a bug where OpenCode model IDs were not being correctly formatted for the CLI, causing errors when selecting models. The fix introduces logic to convert model IDs from the internal opencode-model format to the opencode/model format expected by the CLI. The changes correctly handle various cases, including models from other providers. My review includes a suggestion to refactor the new logic for improved conciseness and maintainability.

Address review feedback from Gemini Code Assist to reduce code repetition. The conditional logic for handling models with/without slashes is now unified into a simpler two-step approach: 1. Strip opencode- prefix if present 2. Prepend opencode/ if no slash exists
