Therock Build To Commit

Resolve TheRock Nightly Build to rocm-systems Commit

Resolves a TheRock nightly build to the exact rocm-systems commit (pin_sha) that was used to produce it, by reading the build's therock_manifest.json from S3.

When to Use

Use this skill when:

• User asks "what rocm-systems commit is in TheRock build X?"
• User provides a TheRock nightly URL (e.g. https://rocm.nightlies.amd.com/packages-multi-arch/deb/YYYYMMDD-<RUN_ID>/index.html) or a bare run-id and wants to know what shipped
• User wants the GitHub tree link for the snapshot used by a nightly build
• Another skill needs the pin_sha for a build before continuing (e.g. therock-commit-in-build)

Unless the user says otherwise, this skill targets the rocm-systems submodule.

Nightly URL Layout (current)

<ROCM_PACKAGE_VERSION> comes from the manifest field rocm_package_version (e.g. 7.14.0a20260624). The date prefix <YYYYMMDD> in the packages URL is the suffix after a in that version string (e.g. 20260624).

Legacy builds (before the multi-arch layout) used:

• Packages: https://rocm.nightlies.amd.com/deb/<YYYYMMDD>-<RUN_ID>/index.html
• Manifest: .../manifests/<GPU_FAMILY>/therock_manifest.json (e.g. gfx94X-dcgpu) instead of .../manifests/therock_manifest.json

When fetching manifests, try the current path first; fall back to the per-GPU_FAMILY path for older runs.

Inputs

The user provides one of:

Optional overrides:

Process

Phase 1: Parse the Run ID

Accept whatever the user pasted and extract the numeric GitHub Actions run id.

INPUT="$1"
# Run ids are >= 10 digits; anchor on that to avoid catching the 8-digit date.
RUN_ID=$(echo "$INPUT" | grep -oE '[0-9]{10,}' | tail -n1)

if [ -z "$RUN_ID" ]; then
  echo "Could not extract a run id from: $INPUT" >&2
  exit 1
fi

Echo the extracted run id back to the user before fetching, so they can confirm.

Phase 2: Build the Manifest URL

Current layout (try this first):

PLATFORM="${PLATFORM:-linux}"

MANIFEST_URL="https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-${PLATFORM}/manifests/therock_manifest.json"

If that 404s, fall back to the legacy per-GPU-family path:

GPU_FAMILY="${GPU_FAMILY:-gfx94X-dcgpu}"
LEGACY_MANIFEST_URL="https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-${PLATFORM}/manifests/${GPU_FAMILY}/therock_manifest.json"

Phase 3: Fetch the Manifest

MANIFEST=$(curl -fsSL "$MANIFEST_URL" || curl -fsSL "$LEGACY_MANIFEST_URL")

If both fail, report the URLs tried. Wrong platform is the most common cause on current builds.

Phase 4: Extract pin_sha for rocm-systems

The manifest is a JSON object with this shape:

{
  "the_rock_commit": "f1e3fc2311fde45bf3e17b0e3349200be9caa4b4",
  "github_run_id": "28066115163",
  "rocm_package_version": "7.14.0a20260624",
  "rocm_version": "7.14.0",
  "submodules": [
    {
      "submodule_name": "rocm-systems",
      "submodule_path": "rocm-systems",
      "submodule_url": "https://github.com/ROCm/rocm-systems.git",
      "pin_sha": "8b2f7145a33519b7f397b1c3636abddb7823538f"
    }
  ]
}

Note: submodule entries live under the top-level submodules array, not at the root. Always walk .submodules[].

Prefer jq:

SUBMODULE_NAME="${SUBMODULE_NAME:-rocm-systems}"

PIN_SHA=$(echo "$MANIFEST" | jq -r --arg name "$SUBMODULE_NAME" '
  .submodules[] | select(.submodule_name == $name) | .pin_sha
')

THE_ROCK_COMMIT=$(echo "$MANIFEST" | jq -r '.the_rock_commit')
ROCM_PACKAGE_VERSION=$(echo "$MANIFEST" | jq -r '.rocm_package_version')

Fallback when jq is unavailable:

read -r PIN_SHA THE_ROCK_COMMIT ROCM_PACKAGE_VERSION < <(echo "$MANIFEST" | python3 -c '
import json, sys
name = "rocm-systems"
data = json.load(sys.stdin)
pin = ""
for entry in data.get("submodules", []):
    if entry.get("submodule_name") == name:
        pin = entry.get("pin_sha", "")
        break
print(pin, data.get("the_rock_commit", ""), data.get("rocm_package_version", ""))
')

If PIN_SHA is empty, list every submodule_name from the manifest so the user can pick a different one:

echo "$MANIFEST" | jq -r '.submodules[].submodule_name'

Phase 5: Derive artifact URLs

# Date prefix from rocm_package_version (7.14.0a20260624 -> 20260624)
DATE_PREFIX="${ROCM_PACKAGE_VERSION##*a}"

if [ -n "$LEGACY" ]; then
  # Pre-migration builds: /deb/ packages layout, no multi-arch tarball.
  PACKAGES_URL="https://rocm.nightlies.amd.com/deb/${DATE_PREFIX}-${RUN_ID}/index.html"
  TARBALL_URL=""
else
  PACKAGES_URL="https://rocm.nightlies.amd.com/packages-multi-arch/deb/${DATE_PREFIX}-${RUN_ID}/index.html"
  TARBALL_URL="https://rocm.nightlies.amd.com/tarball-multi-arch/therock-dist-linux-multiarch-${ROCM_PACKAGE_VERSION}.tar.gz"
fi

Set LEGACY=1 when resolving a pre-migration build (manifest served from the per-GPU-family path, or run found under ROCm/TheRock).

Phase 6: Report

Report back, in this exact shape, so other skills can parse it. <WORKFLOW_REPO> is ROCm/rockrel for current builds and ROCm/TheRock for legacy ones; omit the Tarball: line when it is empty (legacy builds).

Build:            <RUN_ID>          (platform=<PLATFORM>)
TheRock commit:   <THE_ROCK_COMMIT>
ROCm package:     <ROCM_PACKAGE_VERSION>
Submodule:        <SUBMODULE_NAME>
pin_sha:          <PIN_SHA>
Repo snapshot:    https://github.com/ROCm/rocm-systems/tree/<PIN_SHA>
GitHub Actions:   https://github.com/<WORKFLOW_REPO>/actions/runs/<RUN_ID>
Manifest:         <MANIFEST_URL>
Packages:         <PACKAGES_URL>
Tarball:          <TARBALL_URL>

Examples

Example 1: User pastes the current packages URL

INPUT="https://rocm.nightlies.amd.com/packages-multi-arch/deb/20260624-28066115163/index.html"
# RUN_ID -> 28066115163
curl -fsSL "https://therock-nightly-artifacts.s3.amazonaws.com/28066115163-linux/manifests/therock_manifest.json" \
  | jq -r '.submodules[] | select(.submodule_name=="rocm-systems") | .pin_sha'
# -> 8b2f7145a33519b7f397b1c3636abddb7823538f

Example 2: User gives only the run id

RUN_ID=28066115163
curl -fsSL "https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-linux/manifests/therock_manifest.json" \
  | jq -r '.submodules[] | select(.submodule_name=="rocm-systems") | .pin_sha'

Example 3: Legacy build (per-GPU-family manifest)

RUN_ID=22561649510
curl -fsSL "https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-linux/manifests/therock_manifest.json" \
  || curl -fsSL "https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-linux/manifests/gfx94X-dcgpu/therock_manifest.json" \
  | jq -r '.submodules[] | select(.submodule_name=="rocm-systems") | .pin_sha'

Example 4: Also surface package version and tarball link

RUN_ID=28066115163
curl -fsSL "https://therock-nightly-artifacts.s3.amazonaws.com/${RUN_ID}-linux/manifests/therock_manifest.json" \
  | jq '{the_rock_commit, rocm_package_version, rocm_systems_pin: (.submodules[] | select(.submodule_name=="rocm-systems") | .pin_sha)}'
# -> {
#      "the_rock_commit": "f1e3fc2311fde45bf3e17b0e3349200be9caa4b4",
#      "rocm_package_version": "7.14.0a20260624",
#      "rocm_systems_pin": "8b2f7145a33519b7f397b1c3636abddb7823538f"
#    }

Output

This skill produces:

• The pin_sha for the requested submodule (default rocm-systems) in the requested TheRock nightly build
• The the_rock_commit and rocm_package_version for the build
• The GitHub tree URL for the submodule snapshot
• The GitHub Actions run URL for the build
• The manifest, packages index, and tarball URLs

No files are written.

Common Mistakes

Troubleshooting

curl: (22) The requested URL returned error: 403/404

Cause: the constructed MANIFEST_URL does not exist in the bucket for that run id.

Steps:

1. Verify the run id: https://github.com/ROCm/rockrel/actions/runs/<RUN_ID> (legacy pre-June-2026 runs: ROCm/TheRock)
2. Try the current path: .../manifests/therock_manifest.json
3. If that 404s, try the legacy path: .../manifests/gfx94X-dcgpu/therock_manifest.json
4. Confirm platform (linux vs windows)

PIN_SHA is empty

Cause: the submodule name does not match (typo, renamed, or not present in this build).

Steps:

1. List every submodule_name in the manifest:

   curl -fsSL "$MANIFEST_URL" | jq -r '.submodules[].submodule_name'
   

2. Ask the user which one they want; rerun with SUBMODULE_NAME=<chosen>.

jq: command not found

Use the python3 fallback shown in Phase 4. Do not skip JSON parsing in favor of grep - the manifest can change shape.

Integration with Other Skills

Notes

• The manifest is hosted in a public S3 bucket; no auth is required for curl.
• Current multi-arch nightlies publish a single manifest at manifests/therock_manifest.json (no per-GPU-family subdirectory). The pin_sha is the same across architectures.
