## What it does

This skill operates the `btca` CLI. It adds git repositories, local directories, and npm packages as searchable context, then asks questions against one resource or several resources at once.

Resources live in the project `btca.config.jsonc` or the global `~/.config/btca/btca.config.jsonc`. Project configuration takes precedence and controls the provider, model, and resources. `btca ask` can also take a one-off resource directly, without saving it to configuration.

Connect a provider with `btca connect` before asking questions. A disconnected provider stops requests, so checking that first avoids a failed research step.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add davis7dotsh/better-context --skill btca-cli -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/btca-cli/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/btca-cli/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add davis7dotsh/better-context --skill btca-cli -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/btca-cli/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add davis7dotsh/better-context --skill btca-cli -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/btca-cli/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install davis7dotsh/better-context btca-cli
```

2. **Manually: put the files in place**
- File: `.github/skills/btca-cli/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add davis7dotsh/better-context --skill btca-cli -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/davis7dotsh/better-context --path skills/btca-cli
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/btca-cli/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add davis7dotsh/better-context --skill btca-cli -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davis7dotsh/better-context/tree/HEAD/skills/btca-cli/SKILL.md

## When to use it
- add a git repository as searchable context
- connect a local documentation directory
- ask a question across several resources
- check configured resource names
- inspect an npm package without saving it

## Example prompts
- Use btca to add `npm:@types/node@22.10.1` as the `node-types` resource.
- Use btca to ask a question across the `react` and `typescript` resources.
- Use btca to check configured resources with `btca resources`.

description: Operate the btca CLI for local resources and source-first answers. Use when setting up btca in a project, connecting a provider, adding or managing resources, and asking questions via btca commands. Invoke this skill when the user says "use btca" or needs to do more detailed research on a specific library or framework.

# 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:

```bash
# 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:

```bash
btca resources
```

Ask a question:

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

## Common Tasks

- Ask with multiple resources:

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

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

```bash
# 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`.
