What it does
Macios Binding Creator is an agent skill from dotnet/macios, published by the product's own GitHub organization. Create C bindings for Apple frameworks in dotnet/macios. USE FOR: binding new APIs, implementing .todo file entries, creating Xcode SDK bindings, binding AVFoundation/UIKit/AppKit or any Apple framework, "bind this framework", "implement these APIs". DO NOT USE FOR: Xcode beta version bumps (use macios-xcode-beta-update skill), CI failure investigation (use macios-ci-failure-inspector skill).
Its SKILL.md is about 7.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/binding-patterns.md` and `references/test-workflow.md`).
It sits in Mobile, covering iOS development and Failing and flaky tests. It works with C#, .NET, Xcode and macOS. The repository describes itself as: .NET for iOS, Mac Catalyst, macOS, and tvOS provide open-source bindings of the Apple SDKs for use with .NET managed languages such as C.
When your agent uses it
- : binding new APIs
- Implementing .todo file entries
- Creating Xcode SDK bindings
- Binding AVFoundation/UIKit/AppKit
Example prompts
- “bind this framework”
- “implement these APIs”
- “/macios-binding-creator”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Understand What to Bind
- Generate Reference Bindings
- Research the Native API
- Implement Bindings
- Build
- Validate with Tests
- Handle Test Failures
What it can do on your machine
Read from SKILL.md and the folder at commit 354c2a6. 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:
makegitxcrundotnet
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Macios Binding Creator loads about 7.3k tokens when it runs, and up to ~29k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 3,124 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,124 words (~7,300 tokens).
“Create C# bindings for Apple platform APIs in the dotnet/macios repository. This skill encodes the end-to-end workflow: from reading .todo files through implementation, building, and validating with xtro, cecil, and introspection tests on all platforms.”
