Qredence Documentation

Prerequisites

Python 3.11+
uv
GitHub CLI (gh) for remote install
Claude Code or OpenAI Codex

Set up the repository

git clone https://github.com/Qredence/qredence-plugins.git
cd qredence-plugins
uv sync --frozen --dev

If a plugin depends on external services, copy .env.example to .env and add the required keys.

Install from GitHub

Install a skill across all supported agents:

gh skill install Qredence/qredence-plugins harness-engineering

Install for a specific agent:

gh skill install Qredence/qredence-plugins harness-engineering --agent claude-code
gh skill install Qredence/qredence-plugins harness-engineering --agent codex

Browse available skills:

gh skill search Qredence/qredence-plugins

Installable skill names: harness-engineering, meta-harness, rlm-wiki, symphony, development, legal, autoresearch-dspy.

Local testing

For local development or session-only testing, point Claude Code at a checkout directly:

claude --plugin-dir ./plugins/<plugin-name>

Then invoke the skill, for example:

/meta-harness:meta-harness

Run a plugin from Codex

When Codex creates a new worktree, .codex/environments/environment.toml bootstraps dependencies with:

uv sync --frozen --dev

Put environment variables (TAVILY_API_KEY, LINEAR_API_KEY, etc.) in Codex settings — setup runs in a separate shell session, so exports won’t persist.
