The instructions your model reads when the skill loads.
Generate data-driven X/Twitter posts for plugin releases with ASCII cards ready for CodeSnap screenshots.
Run /promote vX.Y.Z after tagging a release. Optionally add a title: /promote v2.8.0 "LiveView Streams Overhaul".
All files go to scratchpad/x-posts/{version}-release.md (create directory if needed).
The output file contains three sections:
Collect these metrics (all are verifiable commands — run them, don't estimate):
| Metric | How to get it |
|---|---|
| File count + insertions/deletions | git diff --stat {prev-tag}..{tag} |
| Skill count | ls plugins/elixir-phoenix/skills/ | wc -l |
| Agent count | ls plugins/elixir-phoenix/agents/*.md | wc -l |
| Iron Law count | Grep for numbered Iron Laws in CLAUDE.md |
| Eval scores | make eval-all (run it, report actual numbers) |
| Changelog entries | Read CHANGELOG.md for this version's section |
| Before/after metrics | Depends on release — look for quantifiable changes |
The strongest posts have before/after comparisons. Look for changes in CHANGELOG.md that have measurable deltas (line counts, counts of affected files, error rates, coverage numbers).
The card is the visual centerpiece — it gets screenshotted via CodeSnap and attached to tweet 1.
