changelog

changelog is a skill for Claude Code from gowtham012/Claude-plugins. It costs 35 tokens per session (304 once invoked), scanned A, original, MIT.

A tool that compares a before and after screen recording and writes a user-facing changelog, which is a summary of what changed in a release.

In plain words
What is it for?
Use it to describe added, changed, and removed interface elements, text, colours, and animations between versions.
Why use it?
It removes the need to manually inspect both recordings and turn every difference into release-note wording.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

changelog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Generate changelog comparing videos: $ARGUMENTS

Arguments:

  • $0 = video_before (required)
  • $1 = video_after (required)
  • $2 = version label for before (default: v1)
  • $3 = version label for after (default: v2)

Steps

  1. Call MCP tool mcp__video-insight__generate_changelog with both video paths and version labels.
  2. For each scene_diff, examine keyframe_before and keyframe_after side by side.
  3. Write the changelog:
## $3 — What's New

### Added
- New [component] with [copy from text_added]

### Changed
- [Screen name]: [what changed visually]

### Removed
- [copy from text_removed]

### Design Updates
- New color palette: [translate hex to description]
- New animations: [from motion_types_added]

Be specific — reference exact UI text from OCR. Keep tone user-facing, no technical jargon.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
