bab-plugins

First-party Bab delegate plugins that are installed externally instead of being bundled with bab.

Install

Install all plugins from this repository:

bab add git@github.com:babmcp/plugins.git

Install non-interactively:

bab add git@github.com:babmcp/plugins.git --yes

Included Plugins

• claude — Claude Code
• codex — Codex CLI
• copilot — GitHub Copilot CLI

opencode stays bundled in the main bab repository as the reference plugin.

Repository Layout

claude/
codex/
copilot/

Each plugin directory contains:

• manifest.yaml
• adapter.ts
• prompts/
• optional supporting docs such as RESEARCH.md

Requirements

Each plugin requires its underlying CLI to be installed and authenticated separately.

• claude requires the claude CLI
• codex requires the codex CLI
• copilot requires the standalone copilot CLI

For Copilot CLI installation and auth, use the official docs:

• https://github.com/features/copilot/cli
• https://docs.github.com/copilot/how-tos/copilot-cli

Tool Prompts

Plugins can provide custom system prompts for bab's workflow tools. Add a tool_prompts section to your manifest.yaml:

tool_prompts:
  codereview: prompts/codereview.txt
  debug: prompts/debug.txt
  secaudit: prompts/secaudit.txt

Each key is a tool name, and the value is a path to a plain text file relative to the plugin directory. The prompt replaces the built-in system prompt when a tool routes through a plugin model (e.g. copilot/gpt-4). If a tool is not listed, bab uses its built-in prompt.

Available tool names:

Tool	Description
chat	General conversation
challenge	Challenge/critique ideas
thinkdeep	Deep thinking/reasoning
codereview	Code review
debug	Debugging assistance
analyze	Code analysis
refactor	Refactoring suggestions
testgen	Test generation
secaudit	Security audit
docgen	Documentation generation
tracer	Trace/flow analysis
precommit	Pre-commit checks
planner	Planning tasks
consensus	Multi-model consensus

See Plugin Authoring for full details on precedence and behavior.

Copilot Plugin — Permissions

By default the Copilot adapter does not pass --allow-all to the CLI. This means the Copilot CLI will run with its default (restricted) permissions.

To opt in to full filesystem and network access, add allow_all: true to the role's args in your manifest or role config:

roles:
  - name: default
    args:
      allow_all: true

Or pass it at call time via the delegate tool's role args. Only enable this if you understand the implications — it grants the Copilot CLI process unrestricted access to your machine.
