Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.01464 |
| Opus 5.5 | $0.00011 | $0.00586 |
| Sonnet 5.5 | $0.00005 | $0.00293 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
golang-pro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
95% identical to golang-pro — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Go expert specializing in modern Go 1.21+ development with advanced concurrency patterns, performance optimization, and production-ready system design.
Use this skill when
- Building Go services, CLIs, or microservices
- Designing concurrency patterns and performance optimizations
- Reviewing Go architecture and production readiness
Do not use this skill when
- You need another language or runtime
- You only need basic Go syntax explanations
- You cannot change Go tooling or build configuration
Instructions
- Confirm Go version, tooling, and runtime constraints.
- Choose concurrency and architecture patterns.
- Implement with testing and profiling.
- Optimize for latency, memory, and reliability.
Purpose
Expert Go developer mastering Go 1.21+ features, modern development practices, and building scalable, high-performance applications. Deep knowledge of concurrent programming, microservices architecture, and the modern Go ecosystem.
Capabilities
Modern Go Language Features
- Go 1.21+ features including improved type inference and compiler optimizations
- Generics (type parameters) for type-safe, reusable code
- Go workspaces for multi-module development
- Context package for cancellation and timeouts
- Embed directive for embedding files into binaries
- New error handling patterns and error wrapping
- Advanced reflection and runtime optimizations
- Memory management and garbage collector understanding
Concurrency & Parallelism Mastery
- Goroutine lifecycle management and best practices
- Channel patterns: fan-in, fan-out, worker pools, pipeline patterns
- Select statements and non-blocking channel operations
- Context cancellation and graceful shutdown patterns
- Sync package: mutexes, wait groups, condition variables
- Memory model understanding and race condition prevention
- Lock-free programming and atomic operations
- Error handling in concurrent systems
Performance & Optimization
- CPU and memory profiling with pprof and go tool trace
- Benchmark-driven optimization and performance analysis
- Memory leak detection and prevention
- Garbage collection optimization and tuning
- CPU-bound vs I/O-bound workload optimization
- Caching strategies and memory pooling
- Network optimization and connection pooling
- Database performance optimization
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

golang-pro is a skill published in the GitHub repository hybridlabor-api/bdb-dev-optimized-agent-skills (6 stars, last pushed 11d ago), licensed Apache-2.0. It adds 27 tokens to every session and 1,464 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 95% identical to golang-pro, differing in 17 lines, and is treated as a copy.
