What it does

Whats New is an agent skill from gustavscirulis/snapgrid. Generates a "What's New" / changelog screen shown after app updates with version tracking, feature highlights, and one-time display per version. Use when user wants release notes UI, update notifications, or feature announcements.

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `templates.md`).

It sits in Development, covering Changelog and release notes. The repository describes itself as: SnapGrid is an open-source Mac app for collecting, organizing, and analyzing UI screenshots. It uses AI to automatically detect UI components and patterns, making it a powerful…

When your agent uses it

  • User wants release notes UI
  • Update notifications
  • Feature announcements

Example prompts

  • “Use the whats-new skill to generate a "What's New" / changelog screen shown after app updates with version tracking, feature highlights, and…”
  • “/whats-new”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Project Context Detection
  2. Conflict Detection
  3. Version Access Pattern
  4. Read Templates
  5. Create Core Files
  6. Create UI Files
  7. Create Optional Files
  8. Determine File Location

What it can do on your machine

Read from SKILL.md and the folder at commit eb7eaf4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Glob
    • Grep
    • Bash
    • AskUserQuestion

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are swift).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Whats New loads about 2.7k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 645 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 645 words (~2,687 tokens).

“Generate a complete "What's New" screen that displays after app updates — highlights new features, changes, and improvements with version tracking to ensure it only shows once per update.”
