inference-troubleshooting SKILL.md skillC
inference-troubleshooting from qualcomm/qai-appbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add qualcomm/qai-appbuilder/inference-troubleshooting@git:20260822.fbacac1Pins git:20260822.fbacac1 in mdr.lock. Pin the fingerprint instead.

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
# Inference Troubleshooting (base)
> 🧭 Diagnosis framework: `${APP_ROOT}/factory/chat_features/model-builder/troubleshooting/_diagnosis-framework.md`; this SKILL is the symptom library for the "runtime crash / wrong results" domain.
## Responsibility
Diagnose runtime failures and wrong results when running `.bin`/`.dlc`/`.dll` through
`qai_appbuilder` / `QNNContext`: silent load crashes, stale-artifact low cosine, NCHW/NHWC
input mismatch, multi-model buffer collisions, and Linux HTP transport/version mismatch.
Inference on NPU MUST go through `qai_appbuilder`/`QNNContext` — never `onnxruntime`
(CPUExecutionProvider allowed **only** for baseline comparison in a separate process).
## Trigger signals
- `QNNContext(...)` exits on load (exit 1 / `0xC0000005`, no traceback)
- Inference runs but cosine is abnormally low (e.g. 0.83)
- `Incorrect amount of Input Buffers for graphIdx: 0. Expected: N, received: M`
- `Stub lib id mismatch` / `Failed to create transport ... error: 1008` / `Failed to load skel`
- Wrong predictions (e.g. "window screen" instead of "Samoyed") → suspect NCHW/NHWC

How to install
mdr add qualcomm/qai-appbuilder/inference-troubleshooting@sha256:9d7c04cefb1154daThe 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.
