Btca CLI

btca CLI

btca is a source-first research CLI. It hydrates resources (git, local, npm) into searchable context, then answers questions grounded in those sources. Use configured resources for ongoing work, or one-off anonymous resources directly in btca ask.

Full CLI reference: https://docs.btca.dev/guides/cli-reference

Add resources:

# Git resource
btca add -n svelte-dev https://github.com/sveltejs/svelte.dev

# Local directory
btca add -n my-docs -t local /absolute/path/to/docs

# npm package
btca add npm:@types/node@22.10.1 -n node-types -t npm

Verify resources:

btca resources

Ask a question:

btca ask -r svelte-dev -q "How do I define remote functions?"

Common Tasks

• Ask with multiple resources:

btca ask -r react -r typescript -q "How do I type useState?"

• Ask with anonymous one-off resources (not saved to config):

# One-off git repo
btca ask -r https://github.com/sveltejs/svelte -q "Where is the implementation of writable stores?"

# One-off npm package
btca ask -r npm:react@19.0.0 -q "How is useTransition exported?"

Config Overview

• Config lives in btca.config.jsonc (project) and ~/.config/btca/btca.config.jsonc (global).
• Project config overrides global and controls provider/model and resources.

Troubleshooting

• "No resources configured": add resources with btca add ... and re-run btca resources.
• "Provider not connected": run btca connect and follow the prompts.
• "Unknown resource": use btca resources for configured names, or pass a valid HTTPS git URL / npm:<package> as an anonymous one-off in btca ask.
