The instructions your model reads when the skill loads.
Tell this skill what your product shipped. It writes a polished changelog entry to docs/changelog.md (a living log, newest entry first) and simultaneously produces a content package: tweet thread, LinkedIn post, email snippet, and one-liner.
Input sources: free text from your message, git commits auto-read from the local repo, or GitHub PRs if you provide a repo. Any combination works.
Read these files before each run:
cat references/changelog-format.md
cat references/content-rules.md
cat references/noise-filter.md
echo "GITHUB_TOKEN: ${GITHUB_TOKEN:-not set -- GitHub PR fetching disabled}"
echo "Git: $(git rev-parse --is-inside-work-tree 2>/dev/null && echo 'repo detected' || echo 'not a git repo')"
echo "Changelog: $(ls docs/changelog.md 2>/dev/null && echo 'exists' || echo 'will be created')"
Note whether git is available and whether a changelog already exists. This determines the version label format.
Collect from the conversation:
items -- free text description of what shipped (pipe-separated if multiple). Optional if git is available.since -- how many days back to look. Default: 7. User may say "last 2 weeks" (14) or "since last release."repo -- GitHub "owner/repo" for PR fetching. Optional.version_label -- custom label like "v2.1.0" or "The Speed Update." Optional; default is date-based.If the user said nothing about items AND there is no git repo: Ask "What did you ship? List the features, fixes, or improvements -- one per line."
