Agent adoption scorecard

Trust, audit, and install readiness at a glance

These scores combine public repository metadata, OpenAgentSkill review signals, maintenance freshness, and install readiness. They are a shortlist signal, not a replacement for human review.

Quality

Agent safety v2

54/100 · Avoid automatic install

Experimentalreview

Sparse or mixed signals. Useful for discovery, but not for autonomous installation.

Test manually in an isolated workspace and compare against safer alternatives.

Resolve via API

high

Shell or command execution

Skill metadata references terminal, CLI, shell, subprocess, or command execution workflows.

medium

Network access

Skill likely fetches remote pages, APIs, repositories, or external services.

medium

Filesystem access

Skill may read or write project files, documents, generated artifacts, or local workspace state.

  • High-risk permission hints: Shell or command execution
  • Low GitHub adoption signal

Install targets

Install this skill in your agent workflow

Use the public install endpoint to fetch the command, safety checklist, target prompts, and canonical links for this skill.

skill install

OpenAgentSkill CLI

Resolve policy, run the source installer safely, and report a verified install receipt.

Agent resolve plan

Let an agent verify fit before installing.

The Resolve API returns the selected skill, alternatives, safety policy, audit notes, install target, and copy-paste prompt an agent can follow without scraping this page.

Agent should check

  • Task fit and alternatives from Resolve API.
  • Audit score, trust score, and safety policy warnings.
  • Install target compatibility for Codex, Claude Code, Cursor, or CLI.

Copy prompt

Task: Use Groundwork in this workspace.

Before running it, summarize audit warnings, required permissions, and the fallback skill if install is risky.

Agent handoff

Give an agent the install path, not another directory page.

Overview

# Groundwork

A comprehensive skills library for Claude Code, consolidating proven techniques for planning, design, TDD, debugging, collaboration, and problem-solving.

## Installation

### Via Marketplace

First, add the Groundwork marketplace:

```bash claude plugin marketplace add https://github.com/etr/groundwork-marketplace ```

Then install the plugin:

```bash claude plugin install groundwork ```

#### Update via Marketplace

```bash claude plugin marketplace update groundwork-marketplace

claude plugin update groundwork ```

### Manual Installation

```bash cd ~/.claude/plugins git clone https://github.com/etr/groundwork.git ```

Or use the installer provided with the codebase.

### Other Platforms (Experimental)

> **Warning:** Installation on platforms other than Claude Code is experimental. Skills and agents are automatically transformed to work without Claude Code's plugin system, but some features (hooks, slash commands, skill chaining) may not work identically. Use at your own risk.

Groundwork skills and agents can be installed into other AI coding tools using the included installer script. The installer transforms skill content to remove Claude Code-specific constructs and adapts the format for each target.

#### Supported Targets

| Target | Flag | Description | |--------|------|-------------| | [Codex CLI](https://github.com/openai/codex) | `--codex` | Agents are installed as native custom-agent TOML files with Codex model and reasoning settings | | [OpenCode](https://github.com/opencode-ai/opencode) | `--opencode` | Agents are installed as standalone agent files | | [Kiro](https://kiro.dev) | `--kiro` | Agents use JSON config + prompt file pairs | | Pi | `--pi` | Agents install as `review-`prefixed skills, plus a pre-built TypeScript extension (`pi-extension/`) | | Claude Code | `--claude-code` | Recommends the marketplace install (no transformation needed) |

##### Codex Agent Conversion

Codex agents are written to `.codex/agents/*.toml` for pro
