[!important] The main project has been sunset, as most of the tools can be implemented as skill files that you can add to your agent. I'll be focusing on that instead. The new code will be located at @zaherg/skills.

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 https://github.com/zaherg/bab-plugins

# Or

bab add zaherg/bab-plugins

Install non-interactively:

bab add https://github.com/zaherg/bab-plugins --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.
