/ccc-changelog — What's New
Reads CHANGELOG.md at the repo root and surfaces the most-recent version section in a scan-friendly summary. Works whether invoked directly or triggered by the SessionStart version-transition nudge.
Steps (always in this order)
1. Locate CHANGELOG.md
Read ${CODEX_PLUGIN_ROOT}/../../CHANGELOG.md via the Read tool.
If that fails, try Bash: find ~ -name CHANGELOG.md -path "*/cc-commander/*" 2>/dev/null | head -1 and read the result.
If no CHANGELOG.md is found: output a friendly message — "CHANGELOG.md not found. Visit https://commanderplugin.com for release notes." and exit.
2. Extract the most-recent version section
Parse the file to find the first ## [ header (e.g. ## [4.0.0-beta.11] — 2026-04-23 — ...). Extract everything from that line up to (but not including) the next ## [ header. That is the "current release block".
If an argument (version string) was passed, instead find the section whose header contains that version string.
3. Render a digestible summary
Output in this exact structure:
## CC Commander [VERSION] — [DATE]
**[HEADLINE from changelog section if present, else first sentence of first paragraph]**
[CHANGES — grouped by emoji category, max 5 bullets per category, ≤15 words each]
---
Full notes: CHANGELOG.md
Grouping rules:
- Scan the block for sub-headers (e.g.
### Security, ### Tests, ### UX, ### New skills) — preserve those as bold labels.
- Under each label, output at most 5 bullet points, each compressed to the single most important fact.
- If a section has more than 5 items, append:
…and N more — see CHANGELOG.md.
- Skip sections with zero bullets after filtering.
- Maximum total output: 30 lines (not counting the header).
4. Footer
Always end with:
Run `/ccc` to get started or `/ccc-browse` to explore all 48 skills.
Anti-patterns
- Never dump the raw CHANGELOG.md — always summarize.
- Never truncate mid-sentence — compress, don't cut.
- No numbered lists — bullets only.
- No "Let me know if..." sign-offs.
