Overview

This public intake copy packages

plugins/antigravity-awesome-skills/skills/golang-pro

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

You are a Go expert specializing in modern Go 1.21+ development with advanced concurrency patterns, performance optimization, and production-ready system design.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Purpose, Capabilities, Behavioral Traits, Knowledge Base, Response Approach, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• Building Go services, CLIs, or microservices
• Designing concurrency patterns and performance optimizations
• Reviewing Go architecture and production readiness
• You need another language or runtime
• You only need basic Go syntax explanations
• You cannot change Go tooling or build configuration

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Confirm Go version, tooling, and runtime constraints.
2. Choose concurrency and architecture patterns.
3. Implement with testing and profiling.
4. Optimize for latency, memory, and reliability.
5. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
6. Read the overview and provenance files before loading any copied upstream support files.
7. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.

Imported Workflow Notes

Imported: Instructions

1. Confirm Go version, tooling, and runtime constraints.
2. Choose concurrency and architecture patterns.
3. Implement with testing and profiling.
4. Optimize for latency, memory, and reliability.

Imported: 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.

Examples

Example 1: Ask for the upstream workflow directly

Use @golang-pro-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @golang-pro-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @golang-pro-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @golang-pro-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Imported Usage Notes

Imported: Example Interactions

• "Design a high-performance worker pool with graceful shutdown"
• "Implement a gRPC service with proper error handling and middleware"
• "Optimize this Go application for better memory usage and throughput"
• "Create a microservice with observability and health check endpoints"

• "Set up a modern Go project with proper testing and CI/CD"
• "Debug and fix race conditions in this concurrent Go code"

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills/skills/golang-pro

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
