What it does
Cgo Bindings is an agent skill from Goldziher/ai-rulez. cgo conventions for linking Go to a C or Rust static library: import "C" directives, type/string conversion, CString memory management, thread safety, and Go pointer pinning. Load when generating or reviewing cgo bindings that call a C or Rust core from Go.
Its SKILL.md is about 370 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 Agent Workflows. It works with Rust. The repository describes itself as: One source of truth for AI assistant configs: 14 built-in presets (Claude, Cursor, Copilot, Codex, Gemini, Xum, …), full-parity custom presets, and distributable plugin bundles… The licence is MIT.
When your agent uses it
- Agent Workflows work in your project
Example prompts
- “/cgo-bindings”
What it can do on your machine
Read from SKILL.md and the folder at commit 1192ada. 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:
go
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
Cgo Bindings loads about 371 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 156 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.

- description
- cgo conventions for linking Go to a C or Rust static library: import "C" directives, type/string conversion, CString memory management, thread safety, and Go pointer pinning. Load when generating or reviewing cgo bindings that call a C or Rust core from Go.
- Use
import "C"with// #cgo LDFLAGS:and// #cgo CFLAGS:directives for linking. - Declare C header functions in comment block immediately above
import "C"— no blank line between. - Type mapping:
C.int,C.long,C.char. UseC.CString()andC.GoString()for string conversion. - Memory:
C.CString()allocates — alwaysdefer C.free(unsafe.Pointer(cStr))immediately after creation. - Error handling: return error codes from C functions, convert to Go
errorvalues. Check all return values. - Link Rust static libraries:
// #cgo LDFLAGS: -L./target/release -lmylib. Build Rust withcrate-type = ["staticlib"]. - Thread safety: C functions called from Go may run on any OS thread. Use
runtime.LockOSThread()when needed. - Go pointer passing: use
runtime.Pinner(Go 1.21+) to pin Go memory passed to C. Never pass Go pointers without pinning. - Test with
go test(requiresCGO_ENABLED=1). Mock C layer for unit tests, use integration tests for real FFI. - Build:
CGO_ENABLED=1 go build. Cross-compilation requires appropriate C toolchain. - Anti-patterns: leaking
C.CStringmemory, passing unpinned Go pointers to C, ignoring C return codes.
