Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Operator Patching (base)
> 🧭 Diagnosis framework: `${APP_ROOT}/factory/chat_features/model-builder/troubleshooting/_diagnosis-framework.md`; this SKILL covers unsupported operator replacement.
## Responsibility
Replace unsupported operators (`Einsum`, `GridSample`, `ScatterND`, `Mod`, `Floor`, `Ceil`, `Round`)
with QNN-compatible equivalents from supported base ops (`MatMul`, `Reshape`, `Transpose`,
`Concat`, `Div`, `Mul`, `Sub`, `Where`, `Add`), **in-memory only**. Patch at whichever stage fails.
## Trigger signals
- Converter/context-binary error: operator name + `unsupported` / `not implemented`
- `0xc26 Op validation failed` on a specific node
- `--dry_run` flags op as unsupported
- `Failed to compile layer 'Einsum_123'`
## Core knowledge
### RULE 1 — check input TYPES first
Same op needs different patch for INT vs FLOAT. Determine types from **producer node**:
| Producer | Output type |
|----------|-------------|
| TopK (indices) | INT64 |
| Constant data_type=7/=1 | INT64 / FLOAT32 |
| Conv / MatMul / Gemm | FLOAT32 |
| Softmax / Sigmoid / Relu | FLOAT32 |
| Reshape / Transpose | inherits |

How to install
mdr add qualcomm/qai-appbuilder/operator-patching@sha256:a84196ac6c3cd0f5The line at the top of this page pins the label git:20260822.fbacac1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
