Give Ox Alpha documentation for a custom language that cannot be in its training data, then implement the game and language feature in separate stages to test document reading, sustained coding, and regression verification.
Suitable tasks: Custom DSLs, internal SDKs, lightly documented applications, and game prototypes.
Unsuitable tasks: Production repositories without a test entry point or rollback path, or tasks where generated code is treated as proof of correctness.
Applicable model version: Ox Alpha; no version snapshot is provided.
Applicable clients, agents, or APIs: OpenCode CLI; the post explicitly describes using OpenCode.
Recommended reasoning levels and parameters: Not disclosed; fix the context, tool permissions, and timeout for long tasks.
The original post does not publish complete turn-by-turn prompts. The following is a reusable workflow derived from the public sequence and should not be quoted as the original prompt:
Use the custom-language documentation in this repository to implement a simple platform game.
Stage 1: Read and summarize the documentation. List the syntax, runtime method, and uncertainties; do not guess semantics that are not documented.
Stage 2: Implement a playable platform game with 10 levels. Build the smallest runnable version first, then verify each level.
Stage 3: Run the existing checks or a minimal regression suite. Report whether each level starts, whether input works, and why any check fails.
Stage 4: Add a modulo operator. Update parsing, execution, error handling, and documentation, and add tests for positive, negative, zero, and invalid inputs.
Stage 5: Run the full regression suite again. Change only task-relevant files and finish with a file list and unresolved issues.Put the custom-language documentation in the repository and state that it is authoritative.
Split “implement the game” and “add the language feature” into separate rounds so regressions are visible.
Require runtime results and failure causes after every round instead of code alone.
Use a reversible branch; custom-language correctness must be checked by the runtime or tests.
The author says that, after receiving the documentation, the model completed a 10-level platform game and added a modulo operator. The author also says the level design was not great but the functionality worked. No repository, commit, or test log is published.
