What this skill does
This skill runs an autonomous Ralph Wiggum coding loop using the ralph CLI with OpenCode as the agent provider.
It repeatedly executes the same coding prompt until:
- The success criteria are met, OR
- The completion promise is printed, OR
- Max iterations are reached
The loop is optimized for free OpenCode Zen models and includes a fallback chain in case models are rate-limited, disabled, or removed.
When to use
Use this skill when you want autonomous coding execution such as:
- Fixing failing tests
- Implementing scoped features
- Refactoring codebases
- Resolving lint/type errors
- Running build-fix loops
- Multi-iteration debugging
You MUST be inside a git repository before running Ralph.
Free model fallback order
Always attempt models in this order:
opencode/kimi-k2.5-free← Best coding performance (limited time free)opencode/minimax-m2.1-freeopencode/glm-4.7-freeopencode/big-pickle← Free stealth model fallback
If a model fails due to availability or quota, immediately retry using the next model without changing the prompt or loop parameters.
Failure triggers for fallback
Fallback if you encounter errors like:
- model disabled
- model not found
- insufficient quota
- quota exceeded
- payment required
- rate limit
- provider unavailable
How to run the loop
Attempt #1 (primary model)
Run:
ralph "
Success criteria:
- Build passes
- Tests pass
Completion promise:
--agent opencode
--model opencode/kimi-k2.5-free
--completion-promise "COMPLETE"
--max-iterations 20
Attempt #2 (fallback)
If attempt #1 fails due to model issues, rerun with:
--model opencode/minimax-m2.1-free
Attempt #3 (fallback)
If attempt #2 fails:
--model opencode/glm-4.7-free
Attempt #4 (final fallback)
If attempt #3 fails:
--model opencode/big-pickle
Tasks mode (for large projects)
For multi-step execution:
ralph ""
--agent opencode
--model opencode/kimi-k2.5-free
--tasks
--max-iterations 50
Fallback model order still applies.
Plugin troubleshooting
If OpenCode plugins interfere with loop execution, rerun with:
--no-plugins
Sanity check available Zen models
If free model availability changes, check:
https://opencode.ai/zen/v1/models
Update fallback order if needed.
Safety notes
- Always run inside a git repo
- Set iteration limits to avoid runaway loops
- Ensure prompts contain verifiable success criteria
- Review diffs before merging autonomous changes
Example usage
Fix failing TypeScript errors:
ralph "Fix all TypeScript errors in the repo.
Success criteria:
- tsc passes
- Build succeeds
Completion promise:
--agent opencode
--model opencode/kimi-k2.5-free
--completion-promise "COMPLETE"
--max-iterations 20
