Tell the skill what your product shipped. It writes a polished dated entry to a living docs/changelog.md and produces a ready-to-use content package: tweet thread, LinkedIn post, email snippet, and one-liner.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# product-update-logger
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.
## Reference Files
Read these files before each run:
```bash
cat references/changelog-format.md
cat references/content-rules.md
cat references/noise-filter.md
```

## Step 1: Setup Check
```bash
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.

## Step 2: Parse Input

How to install
mdr add varnan-tech/opendirectory/product-update-logger@sha256:5f4390769146b63dThe line at the top of this page pins the label git:20260423.81bc5ea, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
