Pull request overview

Hardens gh run view --log output against terminal escape-sequence injection by sanitizing log content before printing.

Changes:

  • Sanitize workflow log output via asciisanitizer in copyLogWithLinePrefix.
  • Add a unit test covering common OSC/CSI escape sequences.
  • Add an end-to-end acceptance script that asserts ESC bytes are not present in rendered logs.

acceptance/testdata/workflow/run-view-log-escape-sequences.txtar Adds acceptance coverage verifying gh run view --log output contains no raw ESC bytes.

  • copyLogWithLinePrefix currently ignores scanner.Err(). With the added transform.NewReader layer, any transform/scan error (including bufio.ErrTooLong) would cause truncated output while still returning nil, hiding failures from callers. Return scanner.Err() after the scan loop (and optionally include context in the error) so errors are surfaced.
	scanner := bufio.NewScanner(sanitized)
	for scanner.Scan() {
		fmt.Fprintf(w, "%s%s\n", prefix, scanner.Text())
	}
	return nil

### Release Notes

<details>
<summary>cli/cli (cli/cli)</summary>

### [`v2.92.0`](https://github.com/cli/cli/releases/tag/v2.92.0): GitHub CLI 2.92.0

[Compare Source](cli/cli@v2.91.0...v2.92.0)

#### Support GitHub Enterprise Cloud (GHEC) in `skill` commandset

Now `gh skill` subcommands (`install`, `preview`, `publish`, `search`, `update`) are able to work with [GHEC](https://docs.github.com/en/enterprise-cloud@latest/admin/overview/about-github-enterprise-cloud) hosts with data residency.

#### Add `--allow-hidden-dirs` flag to `skill preview`

Following the addition of `--allow-hidden-dirs` to `skill install` in the previous release, now the flag is also supported in `skill preview`, allowing users to preview skills located in hidden (dot-prefixed) directories such as `.claude/skills/`, `.agents/skills/`, and `.github/skills/`.

### [`v2.91.0`](https://github.com/cli/cli/releases/tag/v2.91.0): GitHub CLI 2.91.0

[Compare Source](cli/cli@v2.90.0...v2.91.0)

#### GitHub CLI now collects pseudonymous telemetry

To better understand how features are used in practice, especially as agentic adoption grows, GitHub CLI now sends pseudonymous telemetry.

See [Telemetry](https://cli.github.com/telemetry) for more details on what's collected, why, and how to opt out.

#### Support more agents in `gh skill`

Thanks to community feedback, `gh` now supports a large number of agent hosts. Run `gh skill install --help` for the list of available agents.

#### Improve skill discovery

`gh skill install` now adds the `--allow-hidden-dirs` flag to support discovering skills in hidden (dot-prefixed) directories such as `.claude/skills/`, `.agents/skills/`, and `.github/skills/`.

#### Detect skills re-published from other sources

GitHut CLI now detects if the skill to be installed is re-published from an upstream source and offers the option to install it from there. The `--upstream` flag is also added for non-interactive use cases.

#### What's Changed

##### ✨ Features

- Add support for installation in multiple agent hosts in `gh skills install` by [@&#8203;tommaso-moro](https://github.com/tommaso-moro) in [#&#8203;13209](cli/cli#13209)

- feat(skills): detect re-published skills and offer upstream install by [@&#8203;SamMorrowDrums](https://github.com/SamMorrowDrums) in [#&#8203;13236](cli/cli#13236)

##### 🐛 Fixes

- fix(skills): match skills by install name in preview command by [@&#8203;SamMorrowDrums](https://github.com/SamMorrowDrums) in [#&#8203;13249](cli/cli#13249)
