zero-noise

Structural silence. Clean code that means what it says.

A universal plugin for Claude Code, Antigravity (agy), OpenCode, and OpenAI Codex (with support for Kimi, Grok, and any MCP-compliant agent) that enforces zero-noise refactoring: DRY, early return, semantic predicates, and algebraic simplification — across Go, Rust, TypeScript, Python, C#, and Zig.

---

What it does

• Audits structural noise: deep nesting (>2 levels), anonymous closures in argument position, raw conditionals, duplicated literals, and commented-out dead code.
• Auto-fixes algebraic simplifications with --fix (De Morgan’s laws, endsWith shortcuts, and boolean return cleanups).
• Proposes machine-applicable fixes via plan / propose_fixes — guard, predicate, constant, and closure rewrites, each locked to the source SHA-256 (expected_hash) and composable into a single patch.
• Validates that the noise score is strictly lower after the refactor with compiled native Zig engine with zero external runtime dependencies.

OpenCode

Auto-discovered via .opencode/agent/ and .opencode/command/. See .opencode/INSTALL.md for detailed setup.

Install via opencode.json: Add zero-noise to the plugins array (globally in ~/.config/opencode/opencode.json or project-level opencode.json):

{
  "plugins": [
    "zero-noise@git+https://github.com/xdvi/zero-noise.git"
  ]
}

Or from a local clone:

{
  "plugins": [
    ""
  ]
}

Global MCP Configuration in opencode.json: Configure the zero-noise MCP server in ~/.config/opencode/opencode.json (or project-level opencode.json):

{
  "mcp": {
    "zero-noise": {
      "type": "local",
      "command": [
