ROCm Doctor

Given a "ROCm / PyTorch / llama.cpp isn't working on my AMD GPU" complaint, identify which known misconfiguration is the cause and either fix it (with consent) or hand back the exact next step.

This skill does not probe or reason on its own. The

rocm

CLI owns the probe, the closed failure-mode catalog, and the fixes; the skill just drives it and relays the results. The catalog is a closed list — if the symptom doesn't match a known mode, route the user upstream instead of guessing.

Scope gate — check before anything else

Read the user's symptom and answer one question first: is this an AMD GPU?

If it is not — an NVIDIA / Intel / Apple GPU — then stop and decline:

Say plainly that it is out of scope for this skill and why (not an AMD GPU).
Give no troubleshooting for it: no commands to run, no driver or CUDA advice, no diagnostic checklist, no "try this first" — not even generic GPU suggestions. Point at the vendor's own docs and stop there.
Do not run
```
rocm examine
```
/
```
rocm diagnose
```
/
```
rocm fix
```
.

Being helpful here means being honest about the boundary — confidently-wrong advice for a stack this skill does not cover is worse than no advice. Only continue past this gate when the GPU is AMD. See Out of scope.

WSL2 is in scope and does not stop this gate. It is a platform family of its own, with its own catalog entries covering

/dev/dxg

, the DXCore handoff, ROCDXG, the distro floor, the Windows host driver and WSL 1. Do not decline a WSL2 user or route them away untouched — run the workflow as for any other platform. The CLI scopes entries itself, so a bare-metal Linux fix is never offered there.

Prerequisites

The
rocm
CLI. This skill is only a driver over it; Phase 0 below installs it with the user's consent if
```
rocm --version
```
fails. Nothing else here is assumed — the CLI does the probing.
Platform: native Linux (in-tree
```
amdgpu
```
module +
```
/dev/kfd
```
), Windows (HIP SDK), or WSL2 (
```
/dev/dxg
```
+ the Windows host driver). NVIDIA/Intel/Apple GPUs and clean-machine installs are out of scope (see Out of scope).
No fixed ROCm version, GPU arch (
gfx…
), or container image is assumed —
```
rocm examine
```
/
```
diagnose
```
detect the installed ROCm, the GPU's
```
gfx
```
target, and container context, and match fixes to what they find. Never hand-set
```
HSA_OVERRIDE_GFX_VERSION
```
(or similar footgun env vars) yourself; let the CLI decide.

Workflow

Only start here once the Scope gate passes — the GPU is AMD. Linux, Windows and WSL2 all run the same workflow.

Ensure the
rocm
CLI is present. Everything below shells out to it, so check first and install it if missing:
```
rocm --version
```
If that succeeds, skip to step 1. If it's not found, install it with the user's consent (this fetches and runs an installer that drops the
```
rocm
```
and
```
rocmd
```
binaries into
```
~/.local/bin
```
). Both installers default to the
```
release
```
channel, so no channel argument is needed:
- Linux (x86_64 only):
```
curl -fsSL https://raw.githubusercontent.com/ROCm/rocm-cli/main/install.sh | sh
```
- Windows (PowerShell):
```
irm https://raw.githubusercontent.com/ROCm/rocm-cli/main/install.ps1 | iex
```
There is no macOS build.
```
install.sh
```
refuses anything but Linux x86_64, so on any other host hand the user the install page and stop rather than suggesting the command anyway. To pin an unreleased build instead, pass
```
nightly
```
(
```
sh -s -- nightly
```
, or
```
$env:ROCM_CLI_CHANNEL = "nightly"
```
).
After install, confirm
```
~/.local/bin
```
is on
```
PATH
```
and re-run
```
rocm --version
```
. If it still isn't available, hand the user the install page (https://github.com/ROCm/rocm-cli) and stop.
Diagnose. Pass the user's error text as the symptom:
```
rocm diagnose --symptom "<paste the exact error>" --json
```
Read the JSON:
- ```
has_match
```
  — the gate. True means a cause cleared the threshold and you may propose a fix; false means nothing was established, so route upstream. Do not substitute "is
```
matched
```
  empty?": several checkers open with a nonzero base score for a merely potentially relevant situation (a container, an APU beside a discrete GPU), so a healthy host still returns a non-empty
```
matched
```
  of sub-threshold entries. Gating on emptiness proposes a fix for a machine with nothing wrong.
- ```
matched[]
```
  — ranked causes, each with
```
id
```
  ,
```
title
```
  ,
```
score
```
  (0–100),
```
evidence[]
```
  , and a
```

```
  (with
```

  ,
```

```

```

  , and the
```

```
auto_applicable
```
  flags).
```
score >= 75
```
  = high confidence;
```
50–74
```
  = likely (confirm one more piece of evidence with the user first).
- ```
out_of_scope
```
  — set only when the host's platform family has no catalog entries at all. Linux, Windows and WSL2 are all covered, so this does not fire for WSL2. When it is set, nothing was checked — say so rather than implying the machine looks fine. First, if the user's symptom clearly names an app that ships its own runtime (Lemonade, Ollama, LM Studio), route them to that app's tracker (see Framework routing) — those trackers apply regardless of platform. Otherwise relay the
```
out_of_scope
```
  message and stop.
- ```
route_when_no_match
```
  — when
```
has_match
```
  is false, hand the user this upstream tracker; do not speculate. Note the CLI picks this target from the host-detected framework, not from the symptom text — so for an app named only in the symptom, route it yourself per Framework routing.
Propose the fix. Show the top match's
```
title
```
,
```
evidence
```
, plan, and
```
verify
```
command. Only propose applying it when the user is on board.
Apply with consent. For an auto-applicable fix:
```
rocm fix <fix-id>            # auto fixes: prompt before changing anything
rocm fix <fix-id> --dry-run  # show the exact change, touch nothing
rocm fix <fix-id> --yes      # required to apply in a non-interactive shell
```
Only the four auto-applicable fixes are ones the CLI runs itself. The other 22 are print-only (bootloader, kernel, reinstall, Windows driver, …):
```
rocm fix <id>
```
just prints the plan for the user to run themselves — no prompt, and the CLI never performs those.
Of the four, two do not always mutate:
- fix-2-unset-override
  mutates on Windows only. On Linux it reports where the override is set and which rc files carry it, then stops — it will not edit the user's dotfiles. So there is no prompt to answer and nothing for
```
--dry-run
```
  to preview. Tell the Linux user what to edit; do not describe it as a change the CLI made or previewed.
- fix-9-igpu-dgpu
  mutates only when
  --device-index N
  is passed. Without it — on either platform — the runner just prints the
```
rocminfo
```
  /
```
hipInfo
```
  query that identifies the discrete GPU's index and returns 0; there is no prompt, no
```
--dry-run
```
  preview, and nothing is pinned. Once the user knows N, re-run with
```
rocm fix fix-9-igpu-dgpu --device-index N
```
  .
Verify. Have the user run the
```
verify
```
command from the diagnosis.

Use

rocm examine

(or

rocm examine --json

) when you only need the host state (GPU, driver, ROCm install, groups, framework) without a diagnosis.

Framework routing

rocm diagnose

covers frameworks that build against the system ROCm/HIP:

PyTorch, llama.cpp — in scope; diagnose normally.

Apps that ship their own ROCm runtime aren't diagnosed here — route the user to the right tracker. This routing is yours, not the CLI's: the host probe reports only

pytorch

llama-cpp

unknown

, so

route_when_no_match

can never name one of these apps. Use the list below.

Lemonade → https://github.com/lemonade-sdk/lemonade/issues
Ollama → https://github.com/ollama/ollama/issues
LM Studio → in-app support (no public repo)
Anything else with no catalog match → ROCm core: https://github.com/ROCm/ROCm/issues (this is what
```
route_when_no_match
```
returns by default).

Out of scope

NVIDIA / Intel / Apple Silicon GPUs, and fresh installs on a clean machine (a setup task, not a diagnosis). Exit cleanly and say so.

WSL2 is not in this list. It is a supported platform family with its own catalog entries — see reference.md.

Rules

Never run the workflow — or offer any troubleshooting, generic GPU fixes included — for a non-AMD GPU. State it is out of scope and stop. This does not apply to WSL2, which is in scope and runs the normal workflow.
Never invent a fix. If
```
rocm diagnose
```
returns no match, route upstream.
Never run a mutating fix without the user's explicit OK; prefer
```
--dry-run
```
first. New failure modes are added to the CLI catalog, not improvised here.

See reference.md for the full closed catalog and the CLI command/exit-code reference.
