Find the First TheRock Nightly Build to Include a Commit

Walks scheduled runs of the Multi-Arch Release workflow on ROCm/rockrel (workflow id 265449761 — the workflow that currently publishes nightly manifests to S3) in chronological order, starting at (or just before) the commit's date, and reports the first build whose rocm-systems pin_sha is a descendant of (or equal to) the user's commit — i.e. the commit is an ancestor of the build's pin_sha.

Legacy: Before mid-June 2026, nightlies used Release portable Linux packages on ROCm/TheRock (workflow id 161312296, now deleted). For commits first shipped in that era, pass --legacy (equivalent to --workflow-repo ROCm/TheRock --workflow 161312296). The default rockrel walk may report a later run as "first" if the commit actually shipped in an earlier TheRock nightly.

Backed by an executable helper script: find_first_build.py.

When to Use

Use this skill when:

• User asks "what is the first nightly build to include commit <sha>?"
• User asks "has my fix shipped yet, and if so where can I grab it?"
• Bisecting which nightly first contained a regression
• Verifying a PR landed in a downstream consumer (a TheRock-based image, package, or wheel)

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

Inputs

Prerequisites

• gh CLI installed and authenticated against github.com (see skills/git-gh-client/SKILL.md for setup).
• python3 >= 3.8 (standard library only; no pip install needed).
• Outbound HTTPS to github.com and therock-nightly-artifacts.s3.amazonaws.com.

Quick sanity check:

gh auth status
python3 --version

Process

The skill is a thin wrapper around the bundled script. The agent's job is to:

1. Confirm prerequisites.
2. Determine the SKILL directory (the folder containing this SKILL.md); call it SKILL_DIR. Typically ~/.claude/skills/therock-first-build-with-commit/.

3. Invoke the script with the user's commit:

   python3 "$SKILL_DIR/find_first_build.py" --commit <SHA>

4. Stream the per-iteration progress (stderr) to the user as it runs. When done, present the final result (stdout) verbatim — it is already a bullet list; do not reformat it into a table or prose.

5. If the user wants to pipe the result into other tooling, add --json:

   python3 "$SKILL_DIR/find_first_build.py" --commit <SHA> --json

Resolving non-SHA inputs

If the user provides a PR URL/number instead of a SHA, resolve it first:

gh api repos/ROCm/rocm-systems/pulls/<PR_NUMBER> \
  --jq '{merged, merge_commit_sha, head_sha, base_ref: .base.ref}'

Use merge_commit_sha (the commit that landed on the base branch) - not head_sha (the tip of the PR branch before merge). Then pass merge_commit_sha to --commit.

Examples

Example 1: Recent commit — first rockrel nightly

SKILL_DIR=~/.claude/skills/therock-first-build-with-commit
python3 "$SKILL_DIR/find_first_build.py" \
  --commit d22352b782e728115786965046088fc4a71341fb

Sample stderr (progress):

Example 1b: Pre-migration commit — use --legacy

For commits first shipped before the rockrel migration (~2026-06-12), walk the deleted TheRock workflow:

python3 "$SKILL_DIR/find_first_build.py" \
  --commit 570dcd3205005305b32b50996be1d7154d399c4a \
  --legacy

Legacy run URLs use https://github.com/ROCm/TheRock/actions/runs/<RUN_ID> and per-GPU-family manifest paths.

Example 2: Commit hasn't shipped yet

python3 "$SKILL_DIR/find_first_build.py" --commit <fresh_sha>

Final stdout:

No nightly build in the inspected window contains <fresh_sha>.
  Inspected runs: 1 (since 2026-06-03)
  The commit may still ship in a later nightly; rerun later or widen --max-runs / --since.

Exit code is 5 (no match). Suggest the user rerun in a day, or widen the window if their commit is older.

Example 3: Old commit - widen the search window

python3 "$SKILL_DIR/find_first_build.py" \
  --commit <old_sha> \
  --since 2026-03-01 \
  --max-runs 90

Example 4: JSON output for piping

python3 "$SKILL_DIR/find_first_build.py" --commit <sha> --json \
  | jq '.first_build.run_id // empty'

Example 5: PR -> first build (compose with gh)

PR=6445
COMMIT=$(gh api repos/ROCm/rocm-systems/pulls/$PR --jq .merge_commit_sha)
python3 "$SKILL_DIR/find_first_build.py" --commit "$COMMIT"

Output

This skill produces:

• Per-iteration progress on stderr (one line per nightly run, with status and ahead/behind counts).
• Final result on stdout - either a human-readable bullet list (default) or a JSON object (--json).
• Exit codes: 0 found, 3 invalid input, 4 upstream/network failure, 5 exhausted window without finding. (5 rather than 2 so callers can distinguish "no match" from Python's argparse default of 2.)

No files are written.

Common Mistakes

Troubleshooting

Many manifest=missing (skipped) lines

Cause: not every workflow run publishes artifacts. Failed, cancelled, or in-progress runs typically have no manifest. The script skips them and continues.

If all runs are skipped, verify manifest availability against one known-good build using therock-build-to-commit:

curl -fsSL https://therock-nightly-artifacts.s3.amazonaws.com/<RUN_ID>-linux/manifests/therock_manifest.json | head -c 200

For legacy builds, fall back to .../manifests/gfx94X-dcgpu/therock_manifest.json.

gh rate-limit errors

Cause: anonymous rate limit hit, or token scope too narrow.

Steps:

1. Confirm a personal token is configured: gh auth status.
2. For ephemeral environments, export GH_TOKEN=<your_pat> before invoking the script.
3. Reduce --max-runs to limit API calls.

error: could not resolve commit <sha> on ROCm/rocm-systems

Cause: the SHA is on a private fork or not pushed to upstream.

Steps:

1. Verify visibility: gh api repos/ROCm/rocm-systems/commits/<sha> --jq .sha.
2. If the SHA is fork-only, ask the user to push to upstream or rebase the work onto an upstream-visible base.

Script reports status=null

Cause: GitHub returns extra states for very large diffs.

The script logs ahead_by/behind_by either way. Use that as the source of truth: behind_by == 0 -> commit is an ancestor (included).

Notes

• This is the first skill in this repository to ship an executable helper script. The rationale: this lookup has multiple knobs (--commit, --repo, --submodule, --legacy, --workflow, --workflow-repo, --since, --max-runs, --json), needs structured per-iteration progress, and is most useful when reusable from a shell prompt or CI - not just from inside an agent session.
• Standard library only; no pip install required.
• Bounded by GitHub Actions' default 90-day retention - older commits may not be locatable via this method even if they did ship.
• Source recipe: Wiki - Helpful Links and Information, TheRock Nightly Builds section.
