Add changelog-from-changesets agentic workflow

[Copilot]

Automates conversion of .changeset/*.md files to CHANGELOG.md entries via PR.

Implementation

New workflow: .github/workflows/changelog-from-changesets.md

• Engine: Claude 3.7 Sonnet
• Triggers: Weekly schedule + manual dispatch
• Execution:
  1. Detects pending changesets in .changeset/
  2. Runs node scripts/changeset.js release --yes to update CHANGELOG.md
  3. Extracts version and bump type from updated changelog
  4. Creates PR via safe-outputs with version details and changelog excerpt

Safe-outputs config:

safe-outputs:
  create-pull-request:
    title-prefix: "chore: "
    labels: [automation, changelog]
    draft: false

Tools enabled: bash, edit, github MCP (repos, pull_requests)

Reuses existing changeset.js script logic—no duplicate version bump calculations or changelog formatting. The script handles git operations internally; workflow ignores push failures and delegates PR creation to safe-outputs.

Original prompt

Create an agentic workflow that:

Convert .changeset/*.md files into the CHANGELOG.md notes (see changesets.js script)

Using the latest release information and produces a PR. Use Claude.

• The create_pull_request example includes fields that are not part of the safe-outputs tool schema here (base, draft). With additionalProperties: false in the tool schema, including these will cause the tool call to be rejected. Remove unsupported fields and rely on the safe-outputs handler config for base branch/draft behavior.

Run: ${{ github.server_url }}/${{ github.repository }}/actions/runs/${{ github.run_id }}`,
  base: "main",
  draft: false

The create_pull_request example omits the branch parameter. In the compiled workflow, safe-outputs validation requires branch for create_pull_request payloads, so the tool call will fail without it. Update the instructions/example to always provide a deterministic branch name (e.g., derived from ${next_version} + date).

Suggested change

	```javascript
	create_pull_request({
	```javascript
	const branch = `chore/changelog-${next_version}-${new Date().toISOString().slice(0, 10)}`;
	create_pull_request({
	branch,

current_tag=$(git tag -l | tail -1) does not reliably pick the latest version tag (tag listing is not guaranteed to be sorted by version or creation date). This can cause incorrect GH_AW_CURRENT_VERSION and downstream version/bump calculations. Use the same approach as scripts/changeset.js (git describe --tags --abbrev=0) or explicitly sort tags by semver / creatordate before selecting.

The workflow hard-codes main by creating/checking out a local main branch for script compatibility. If the repo default branch differs or the workflow is dispatched from a non-default ref, this can generate changelog entries from the wrong commit and/or fail git operations in unexpected ways. Prefer checking out the actual default branch (e.g., ${{ github.event.repository.default_branch }}) and fail/noop when not on it, rather than creating a new local main branch.

processed_count is computed via git diff --stat .changeset/ | grep -c "delete", but git diff --stat output typically does not contain the string "delete" even when files are removed, so this will usually report 0. Use git diff --name-status -- .changeset | grep '^D' | wc -l (or similar) to count deletions reliably.

Suggested change

	# Count how many changesets were processed
	processed_count=$(git diff --stat .changeset/ | grep -c "delete" || echo "0")
	# Count how many changesets were processed (deleted from .changeset/)
	processed_count=$(git diff --name-status -- .changeset | grep '^D' | wc -l || echo "0")
