• Image 20260720.247.2 ships GitHub CLI 2.96.0 according to its official manifest. Changing this to 2.93.0 is an incorrect downgrade and contradicts the previous value.

- **Version**: 2.93.0

Skills-Based Review 🧠

Applied /grill-with-docs — this is a documentation-only update; no code changes to review.

📋 Observations

Positive Highlights

• ✅ Metadata fields (Last Updated, Source, Image Version, Kernel Version) are all consistently updated
• ✅ Dockerfile examples updated to reflect the new Go 1.25.12 cached version
• ✅ References section kept in sync with the new image branch

Minor Note

The Recent Changes summary notes GitHub CLI updated to 2.93.0, while the previous version was 2.96.0 (a lower version number). If intentional (e.g., the image pinned an older release), a brief note in the document would prevent future confusion when readers compare versions.

Review: Ubuntu runner image update to 20260720.247.2

Two issues need fixing before merge:

1. GitHub CLI version regression (line ~180): gh version changes from 2.96.0 to 2.93.0. Runner images never ship lower tool versions in newer releases — this is almost certainly an analysis error. Needs re-verification against the source README.

2. Broken Python section (line ~53): The - **Package Managers**: header was removed, leaving pip, pip3, and pipx as structurally orphaned list items.

All other version bumps (kernel, Go, Node, Ruby, Python, Selenium, Git, .NET footnote) look reasonable.

GitHub CLI version appears to be a downgrade — this change updates gh from 2.96.0 → 2.93.0. Runner images ship progressively newer versions; a lower version in a newer image is unexpected and likely an analysis error. Please re-verify against the source documentation at the linked runner-images README.

@copilot please address this.

Broken list structure — the - **Package Managers**: header line was deleted, leaving its child items (pip, pip3, pipx) as orphaned list entries with no parent context. Either restore the header or rewrite as a flat list.

@copilot please address this.

[github-actions]

Request changes — one high-confidence factual error, one structural defect, one ambiguous description.

The three issues found must be fixed before merging:

1. GitHub CLI version regression (line 181): 2.96.0 → 2.93.0 is described as an "update" but is a downgrade. Either the source data is wrong or this should be explicitly labeled a downgrade.
2. Broken Python section structure (line 53): removing - **Package Managers**: leaves pip, pip3, pipx as orphaned bullet points.
3. Contradictory Node.js default description (line 44): "system default in cached PATH" conflates OS-level default with n-managed cached version.

Dropped findings

• Go 1.24.13 listed in Recent Changes as updated: technically it was already at 1.24.13 and unchanged, but this is a minor omission in a summary section, not a blocking issue.
• .NET SDK version annotated with "(confirmed via filesystem)": inconsistent style with other sections, but non-blocking.

GitHub CLI version regresses from 2.96.0 to 2.93.0: a newer image shipping an older version of a tool is almost certainly a data-entry error.

💡 Details

The previous image 20260705.232.1 listed GitHub CLI at 2.96.0. This update to 20260720.247.2 lists it at 2.93.0. Runner images do not regress tool versions. The "Recent Changes" blurb also describes this as an "update", which is internally consistent but factually misleading.

Verify against the upstream source: https://github.com/actions/runner-images/blob/ubuntu24/20260720.247/images/ubuntu/Ubuntu2404-Readme.md

If the upstream README genuinely shows 2.93.0, explicitly call it out as a downgrade — not an update.

Broken list structure in Python section: removing the - **Package Managers**: label leaves pip, pip3, and pipx as orphaned bullet points with no heading.

💡 Suggested fix

The diff removes the parent label but keeps the child items:

-  - **Package Managers**:
     - pip: 24.0
     - pip3: 24.0
     - pipx: 1.11.1

Either restore the - **Package Managers**: label, or promote the items to top-level bullets so they read as named properties of the Python section instead of dangling sub-list items.

[github-actions]

Node.js default version description is contradictory: 24.x (system default in cached PATH) conflates two separate concepts and will mislead users.

💡 Details

The "system default" is the OS-installed Node.js version, while a "cached PATH" version is managed by the n version manager. These are mutually exclusive in the runner model.

The old text 20.x (system default) was accurate and clear. If 24.x is now the first cached version on PATH (effectively overriding system default), the correct wording is something like:

- **Default Version**: 24.x (first cached version on PATH via n)

Or if 24.x is genuinely now the system-installed default, drop the "cached PATH" qualifier.
