whattotest

whattotest is a command for coding agents from scarrillo/release. It costs 10 tokens per session (779 once invoked), scanned A, original, MIT.

A command that creates a WhatToTest document for an Apple TestFlight beta release. The document tells beta testers which changes or areas to check.

In plain words
What is it for?
Use it after creating a public changelog or when preparing a TestFlight beta. It can use changelogs, recent release files, commit history, or release documentation as its source.
Why use it?
Release notes may describe changes without clearly telling testers what to verify. This derives a focused testing document from changelog or release information.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/scarrillo/release/whattotest
Clone the repo
git clone --depth 1 https://github.com/scarrillo/release

Or install release, the plugin that ships this one along with the rest of its 5 commands.

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

whattotest 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 3d 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.

TestFlight WhatToTest Generator

Generate a WhatToTest document for TestFlight beta releases.

Model: Uses the model configured in release-plugin.model (see /release:changelog for model selection).

Instructions

  1. Locate source content (in priority order):

    • If called from /release:changelog: Use the changelog-public.md that was just generated in this session. Do not re-analyze - derive directly from that file.
    • If called directly: Look for source content in this order:
      1. changelog-public.md in the project
      2. Recent changelog files in the project
      3. Git commit history for recent changes
      4. Release notes or version documentation
  2. Check for existing WhatToTest files:

    Search for existing WhatToTest files in ./TestFlight/, checking in this order:

    1. WhatToTest.en-US.txt (default)
    2. Other locale variants (e.g., .de.txt, .fr.txt)

    If existing file(s) found, use the same location and filename.

    Check config for release-plugin.whattotest.onExisting:

    • If "prepend": Prepend new entry without asking
    • If "replace": Replace content without asking
    • If "ask" (default): Prompt the user: "WhatToTest file already exists. How should I handle it?"
      1. Prepend new entry (keep history, newest at top) - Recommended
      2. Replace all (start fresh with only this release)

    If no existing file found, create ./TestFlight/WhatToTest.en-US.txt. Create the TestFlight/ folder if it doesn't exist.

  3. Generate WhatToTest content that is:

    • Under 4000 characters total (hard limit — TestFlight rejects content exceeding this). Count characters before writing the file. If over, condense until it fits.
    • No special characters — use only plain ASCII. Avoid smart quotes, em dashes, bullets (•), or other unicode characters. Use hyphens (-) for lists and straight quotes.
    • Concise and actionable for testers
    • Focused on what testers should specifically test
    • Written in plain language (non-technical)
    • Organized by feature area or priority

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.
