Go (Golang) & Fiber GitHub Copilot Instructions

Production-grade architectural rulebook for Go (Golang) & Fiber. Engineered to eliminate LLM hallucinations, enforce strict deterministic conventions, and prevent architectural drift across Cursor IDE, Claude Code CLI, and autonomous multi-agent pipelines.

02 / DRIFT ANALYSIS & VALUE PROPOSITION

Failure Patterns Prevented for Go (Golang) & Fiber

Without This Rule (Default LLM Behavior)Vulnerable

AI models often write non-idiomatic Go with swallowed errors or unnecessary panic/recover handlers. These rules enforce explicit error checks, structured logging, and clean layered packages.

Hallucination Symptoms

Invokes deprecated or removed APIs from older model training weights
Generates conflicting configuration files and invalid imports
Silently drops type-safety, boundaries, or transaction isolation

With This Rule (Guaranteed Invariants)Deterministic

Check every `if err != nil` explicitly; never swallow errors or ignore returned values.

Propagate `c.Context()` into all database and outgoing HTTP requests.

Keep handlers clean: parse inputs with `c.BodyParser`, delegate to domain service, return JSON.

Avoid package-level global variables; inject database connections via struct receivers.

04 / REPOSITORY PLACEMENT & 3-STEP TERMINAL INSTALLATION

How to Install Go (Golang) & Fiber GitHub Copilot Instructions via Terminal

Step 1: Open Project Directory & Verify Target Placement

Open your terminal and navigate to your project root folder where the .github/copilot-instructions.md file will reside. Ensure the file is placed at the exact path below relative to your project root so the AI engine automatically loads it:

.github/copilot-instructions.md

Step 2: Fetch Rule File via Terminal Command

Run curl, PowerShell, or wget to stream the rule directly from the DevScratchpad raw API endpoint and write it to .github/copilot-instructions.md:

Terminal One-Liner Install

Run directly in your project root to stream and write this rule file with one command.

Raw API Stream

mkdir -p ".github" && curl -fsSL "https://www.devscratchpad.tech/api/raw/copilot-instructions/go-fiber" -o ".github/copilot-instructions.md"

Step 3: Verify and Activate with AI Agent

Launch your AI coding assistant (Universal AI Assistants). The assistant will automatically discover .github/copilot-instructions.md in your repository and apply the architectural guardrails, type constraints, and verification protocols during code generation.
