These are the same changes from the 6.1.5 release notes PR. I needed them available in order to run the prompt. Whichever PR merges first will win.

Step 1 states the fetch-milestone-prs output will be saved under .milestone-prs/${input:milestone}/${input:branch}, but the fetch-milestone-prs skill’s default output is .milestone-prs/<milestone>/ unless --output-dir is explicitly provided. Either update this step to match the skill’s default output location, or add an explicit instruction to run the fetch script with --output-dir .milestone-prs/${input:milestone}/${input:branch} so the documented directory structure is actually produced.

Suggested change

	- Follow the instructions in the [fetch-milestone-prs](.github/skills/fetch-milestone-prs/SKILL.md) skill to fetch all merged PRs for the milestone "${input:milestone}".
	- Follow the instructions in the [fetch-milestone-prs](.github/skills/fetch-milestone-prs/SKILL.md) skill to fetch all merged PRs for the milestone "${input:milestone}", and explicitly provide `--output-dir .milestone-prs/${input:milestone}/${input:branch}` when running the fetch command.
