What it does

Build Dmg is an agent skill from Cyronlee/TransFlow. Build and package TransFlow.app into a DMG installer using create-dmg. Use when the user asks to build DMG, package the app, create an installer, or distribute the application.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile. It works with Xcode. The repository describes itself as: Real-time speech transcription & translation for macOS — fully offline, privacy-first.

When your agent uses it

  • The user asks to build DMG
  • Package the app
  • Create an installer
  • Distribute the application

Example prompts

  • “/build-dmg”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. xcodebuild runs with signing disabled — no developer-specific identity baked in during build
  2. codesign_app re-signs the .app with proper identity and entitlements
  3. create-dmg optionally signs the DMG itself with the same identity

What it can do on your machine

Read from SKILL.md and the folder at commit 56a0a78. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • brew

    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

Build Dmg loads about 958 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 316 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~958

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 316 words (~958 tokens).

“Package TransFlow.app into a DMG installer image.”
