What it does
C Bounds Safety is an agent skill from superagents-lab/xcode27-skills. Guide for the C -fbounds-safety language extension. Covers the language model, pointer annotations, adopting bounds-safety in existing C code, compiler build settings and modes, and runtime debugging of bounds violations.
Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/adoption-strategies.md`, `references/build-settings.md` and `references/common-patterns-and-pitfalls.md`).
It sits in Mobile, covering iOS development and Debugging. It works with Xcode, SwiftUI and iOS. The repository describes itself as: Apple's official Agent Skills exported from Xcode 27 — SwiftUI, UIKit modernization, Swift Testing, C bounds-safety, and security hardening for AI coding agents.
When your agent uses it
- Tasks that involve iOS development
- Tasks that involve Debugging
Example prompts
- “/c-bounds-safety”
What it can do on your machine
Read from SKILL.md and the folder at commit 6f9ff8d. 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
No scripts in the folder and no shell commands in SKILL.md.
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
C Bounds Safety loads about 732 tokens when it runs, and up to ~35k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 234 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 234 words (~732 tokens).
“When helping with -fbounds-safety adoption or code changes, ask clarifying questions about the user's codebase and goals before suggesting changes. For complex tasks involving multiple files or non-trivial annotation decisions, use plan mode to propose an approach before implementing.”
