update-linter-version

name	update-linter-version
description	Update a linter's pinned version in its descriptor YAML. Use when upgrading a linter tool to a new release.

Update the version of linter $linter to $version.

Delegation hint — this is a mechanical edit. If you need a sub-agent for the pin change, use version-bumper (haiku). The build step at the end can be delegated to build-runner (haiku).

Steps:

1. Search megalinter/descriptors/*.megalinter-descriptor.yml for the linter by name
2. Find the version ARG in the install.dockerfile section (e.g., ARG PIP_TOOL_VERSION=X.Y.Z) or version pin in pip/npm arrays
3. Update the version, preserving the renovate comment format:

   # renovate: datasource=pypi depName=tool-name
   ARG PIP_TOOL_VERSION=<new_version>
   

4. If no version was specified, check the tool's package registry for the latest
5. Run make megalinter-build to regenerate Dockerfiles with the new version
6. Do not update CHANGELOG.md — linter version upgrades are logged automatically by the auto-upgrade workflow under Linter versions upgrades
7. To test the updated version in CI, write TEST_KEYWORDS=<linter>_test in the commit message body
