alltest

Agent skill for achieving full test coverage across any project. Follows the open SKILL.md standard.

Works with Claude Code, OpenCode, OpenAI Codex, Cursor, Gemini CLI, Windsurf, and any tool that supports the SKILL.md format.

What it does

Activate the skill and the agent will:

1. Analyze your project's tech stack and existing test setup
2. Map every source file and identify coverage gaps
3. Write tests systematically — highest-impact files first
4. Iterate until coverage targets are met

Coverage targets:

• Goal: 100% line coverage
• Minimum: 80% line coverage
• Hard rule: Every source file with exportable logic gets at least one test

Works with any language: TypeScript, Python, Go, Rust, Java, PHP, Ruby, Elixir, and more.

Install

curl -fsSL https://raw.githubusercontent.com/Epsilondelta-ai/alltest/main/install.sh | bash

The script auto-detects installed tools and copies the skill to the right locations:

Tool	Skill path	Auto-detected
Claude Code	~/.claude/skills/alltest/SKILL.md	Always
OpenAI Codex	~/.codex/skills/alltest/SKILL.md	If ~/.codex/ exists
OpenCode	~/.config/opencode/skills/alltest/SKILL.md	If ~/.config/opencode/ exists

Restart your coding tool after installation.

Manual install

Copy skills/alltest/SKILL.md from this repo into your tool's skills directory:

# Claude Code
mkdir -p ~/.claude/skills/alltest
cp skills/alltest/SKILL.md ~/.claude/skills/alltest/

# OpenAI Codex
mkdir -p ~/.codex/skills/alltest
cp skills/alltest/SKILL.md ~/.codex/skills/alltest/

# OpenCode
mkdir -p ~/.config/opencode/skills/alltest
cp skills/alltest/SKILL.md ~/.config/opencode/skills/alltest/

# Project-level (any tool)
mkdir -p .claude/skills/alltest
cp skills/alltest/SKILL.md .claude/skills/alltest/

Usage

Most tools auto-activate skills based on context. Ask for test coverage and the agent will use the skill automatically.

OpenCode slash command

/alltest

OpenCode + oh-my-opencode skill delegation

task(category="deep", load_skills=["alltest"], prompt="Achieve full test coverage for this project")

Any tool

Write tests to achieve full coverage for this project.

The agent will discover the alltest skill from its description and activate it.

Note (OpenCode): Typing alltest without the / slash does NOT trigger the command. You must use /alltest. Keyword-based triggering (like ultrawork) is an oh-my-opencode built-in feature that does not support custom keywords.
