Converts cuTile GPU kernels (@ct.kernel) to Triton (@triton.jit). Handles standard in-repo conversion, debugging (cudaErrorIllegalAddress, shape mismatch, numerical mismatch), and mapping cuTile idioms (ct.load/ct.store, ct.Constant, ct.launch) to Triton equivalents. Covers dual-kernel layout flags (e.g. transpose=True/False + autotune grid via META) per translations/advanced-patterns.md. Use when converting, porting, or translating cuTile kernels to Triton, or debugging existing Triton translations.

# cuTile → Triton Conversion

Convert `@ct.kernel` kernels to `@triton.jit`. API mapping: [references/api-mapping.md](./references/api-mapping.md) (cuTile → Triton).

*In this skill’s Markdown, Triton launch syntax `kernel［grid］(…)` uses Unicode brackets so link checkers do not parse `[grid](…)` as a hyperlink; use normal ASCII brackets in real Triton code.*

## Instructions

Follow the phase-gated workflow in [translations/workflow.md](./translations/workflow.md). Every conversion should go through **analyze → convert → validate → test → benchmark**, with explicit gates before moving on. Use the documents in [Workflow Selection](#workflow-selection) when the task matches a special case (errors, layout flags, perf).

0. **Optimization strategy (perf-sensitive / attention)** — If the op is **attention, FMHA, sliding window, soft cap, or GQA** (e.g. Gemma `gemma_attention`), read **[references/optimization-strategy.md](./references/optimization-strategy.md)** **before** converting the inner loop, then apply **[§4 Gemma FMHA checklist](./references/optimization-strategy.md#4-gemma-fmha--gemma_attention-conversion-checklist-mandatory)**. For other GEMM/BMM/attention-adjacent kernels, still skim **§2–§3** of that file after TMA is done.

1. **Select path** — Existing TileGym op: standard mode in `translations/workflow.md`. If the cuTile source uses `transpose` / `transpose_v`, dual layouts, or MLA-style paths, read [translations/advanced-patterns.md](./translations/advanced-patterns.md) **before** writing Triton (two kernels + `META` grid, not one kernel + `tl.trans`).
