# The Polyglot Protocol – senior-engineer guardrails for AI coding agents

## Summary
The Polyglot Protocol gives AI coding agents a shared engineering checklist for multi-language repositories. It targets safer code generation through repository discovery, language choice rules, dependency checks, testing, security review, and final validation.

## Problem
- AI coding agents often guess APIs, package names, flags, and project conventions, which can produce code that looks valid but fails review or runtime checks.
- Multi-language repositories raise the risk because the agent must choose the right language, preserve local patterns, and handle different runtimes and toolchains.
- Teams lose time repeating standards that the agent should apply before writing code.

## Approach
- The project packages a portable skill for Codex, Claude Code, OpenCode, and custom coding-agent workflows.
- The protocol requires repository discovery before implementation, then applies rules for language choice, dependency discipline, security, testing, validation, and final review.
- It provides dedicated guidance for 22 languages, including TypeScript, Python, Rust, SQL, Java, Go, Swift, Kotlin, C++, and Zig.
- It tells agents to verify tooling and API claims against local code or official docs, and to label unsupported checks with evidence.
- A local script, `scripts/validate-workspace.py`, checks the protocol workspace.

## Results
- The excerpt reports no benchmarked agent-performance gains, no task-success rate, and no comparison against baseline prompting.
- The project reports `workspace validation: PASS` and `language guidance validation: PASS` with a current score of `100/100`.
- The repository includes guidance for `22` languages and `22` language README files.
- It lists `11` operational files for workflow, validation, and rules.
- It includes adapters for `3` named coding environments: Codex, Claude Code, and OpenCode.
