  • Want a critical review
  • Before App Store submission

Example prompts

  • “/release-review”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep

Workflow steps

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

  1. Project Discovery
  2. Security Review
  3. Privacy Review
  4. UX Polish Review
  5. Distribution Review
  6. API Design Review

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
    • Glob
    • Grep

    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 bash, markdown and 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

Release Review loads about 1.3k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 342 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 passed

The automated check found no risky patterns in SKILL.md.

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 342 words (~1,289 tokens).

“Performs a comprehensive pre-release audit of macOS and iOS applications from a senior developer's perspective. Identifies critical issues that could cause rejection, security vulnerabilities, privacy concerns, and UX problems—with actionable fixes.”
