What it does
Xcode Run Device is an agent skill from xenodium/emacs-skills. This skill should be used when the user invokes "/xcode-run-device" to build the current Xcode project, install the app on a connected iOS device, and launch it.
Its SKILL.md is about 540 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, covering iOS development. It works with Xcode and iOS. The repository describes itself as: Emacs skills for coding agents.
When your agent uses it
- Invokes /xcode-run-device to build the current Xcode project
- Install the app on a connected iOS device
Example prompts
- “/xcode-run-device”
- “/xcode-run-device”
What it can do on your machine
Read from SKILL.md and the folder at commit a158238. 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:
xcrunxcodebuild
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
Xcode Run Device loads about 544 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 245 words of instructions outside code blocks.
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 245 words (~544 tokens).
“Build the Xcode workspace or project under the current working directory and launch it on a wired-connected iOS device via Xcode 15+ devicectl. Requires a configured signing team in the project and a trusted, paired device.”
