User description

Replaces EOL'd trunk-io/trunk-action (exit-127) with deterministic prettier check scoped to changed files + read-only permissions. Validated on phenotype-omlx#172, nanovms#159, PhenoObservability#216.


CodeAnt-AI Description

Replace the broken Trunk workflow with reliable Prettier checks

What Changed

  • Replaces the failing Trunk action with a pinned Prettier installation
  • Pull requests and merge queues check only changed supported files, while scheduled runs check the full repository
  • Skips checks when no supported files changed and reports clear formatting failures with read-only repository access

Impact

✅ Fewer CI failures from unavailable Trunk tooling
✅ Faster pull request formatting checks
✅ Reliable scheduled repository-wide formatting checks

Review Change Stack

📝 Walkthrough

Summary

The workflow replaces the end-of-life trunk-io/trunk-action with a pinned Prettier 3.6.2 check. It checks the full repository on scheduled runs and only changed supported files on pull requests, merge groups, and pushes. It also sets read-only repository permissions.

Must Fix

None identified.

Should Fix

None identified.

Consider

The workflow change was validated against phenotype-omlx#172, nanovms#159, and PhenoObservability#216.

Approve / Request Changes

Approve.

Walkthrough

The workflow replaces Trunk checks with pinned Prettier 3.6.2 validation. Scheduled runs check the repository. Pull requests, merge groups, and pushes check changed supported files with ignore-file handling.

Changes

Prettier workflow migration

Layer / File(s) Summary
Workflow triggers and Prettier setup
.github/workflows/trunk-check.yml
The workflow adds merge group support, read-only contents permission, pinned checkout, and Prettier 3.6.2 installation.
Event-specific formatting validation
.github/workflows/trunk-check.yml
Scheduled runs check the repository. Other events check changed Markdown, YAML, JSON, and MDX files. The workflow handles ignore files, empty file sets, and formatting failures.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 19c53

The workflow replaces the retired CI action with a changed-file Prettier check and read-only permissions, but scheduled checks may miss formatting failures and the CI dependency is installed without integrity verification. The PR is mergeable with explicit owner awareness and follow-up for these bounded CI correctness and supply-chain risks.

Verify the package installation against the deterministic-CI policy.

npm install --global prettier@3.6.2 pins the direct version, but it installs from the live registry without a repository lockfile or checksum. Confirm that this satisfies the repository’s supply-chain policy. Otherwise, use a locked install or verify the package integrity before execution. Zizmor reports this as adhoc-packages.

🌐 Web query:

Prettier CLI documentation no path supplied stdin behavior prettier --check repository path

💡 Result:

The Prettier CLI handles input and path arguments in the following ways based on your query: Input from Stdin: By default, the Prettier CLI does not automatically wait for stdin if no file arguments are provided [1]. To process code via stdin, you should pipe the content to the command [2][3]. Because Prettier infers the parser from the file extension, you must provide the --stdin-filepath flag when using stdin to ensure the correct parser is selected [4][5]. For example: cat file.js | prettier --stdin-filepath file.js Behavior of --check: The --check flag is used to verify if files are formatted, outputting a list of unformatted files and a human-friendly summary [6]. When running prettier --check with no path provided: 1. It does not automatically default to checking stdin; it treats the current directory or provided arguments as the target [6]. 2. If you run prettier --check without any arguments, it may not behave as expected because it expects a file or directory path (e.g., prettier --check. to check the current directory) [7][6]. 3. If an unsupported file is encountered or if no parser can be inferred for a target, the CLI may print an error regarding the parser, though behavior regarding exit codes (0 vs 1) has been subject to updates in recent versions [7]. In summary, --check is designed for checking file structures on disk [6]. If you intend to check formatting for content passed via stdin, you would typically need to pipe the content to Prettier, although the --check flag is primarily intended for file/directory paths rather than direct stdin validation [6].

Pass an explicit repository path to the scheduled Prettier check.

When .prettierignore exists, use prettier --check . --ignore-path .prettierignore. Capture its exit status instead of using || true, because the output filter can miss untagged nonzero results.
