The instructions your model reads when the skill loads.
Generate publish-ready website changelog (docs.streamlit.io format) between two git tags. Uses PR labels (impact:users, impact:internal, change:*) for categorization and rewrites PR titles into user-friendly descriptions.
The GitHub release changelog is auto-generated from .github/release.yml — this skill only produces the website format.
Usage: /generating-changelog <previous-tag> <new-tag> (e.g., /generating-changelog 1.44.1 1.45.0)
If only one tag is given, treat it as the new release tag and fetch the previous tag automatically.
gh api repos/streamlit/streamlit/releases/latest --jq '.tag_name'
git rev-parse -q --verify "refs/tags/<tag>" > /dev/null
git log -1 --format=%ai <new-tag>
Run the fetch script to extract PR numbers from git log and batch-fetch metadata via GitHub GraphQL:
uv run python scripts/changelog_fetch_prs.py <prev-tag> <new-tag>
This produces work-tmp/pr-data.json — a JSON array of {number, title, body, labels, author, related_issues, related_issues_truncated} objects sorted by PR number. The body field contains the first 2500 characters of the PR description.
related_issues is sourced from the same batched GraphQL query (no per-PR N+1 requests) and includes linked issue numbers plus 👍 counts:
