## What it does

This skill instructs the agent to query reference codebases via `btca ask` before building new SDK features. It comes preconfigured for three resources: `vercel-ai` for streaming and structured output, `anthropic-sdk` for provider-specific API calls, and `zod` for validation patterns.

The skill runs autonomously with `user-invocable: false` during debugging or feature design. It strictly relies on the external `btca` CLI: without this tool and its configured resources, the agent cannot query the upstream repositories. Teams can append more source codebases with `btca config resources add -n <name> -t git -u <url> -b <branch>`. The instructions explicitly advise against using this skill for docs lookups or project-local searches.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 reference-sdk
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/reference-sdk
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -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/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/reference-sdk/SKILL.md

## When to use it
- inspect streaming and structured output patterns in Vercel AI SDK
- check tool definition and calling structures in Anthropic SDK
- examine error handling and validation logic inside Zod safeParse
- compare edge-case handling across different provider implementations

## Example prompts
- How does streamObject work in the Vercel AI SDK? Check the reference code.
- Inspect how the Anthropic SDK handles tool calling and definitions.
- Check how Zod safeParse handles errors in its reference implementation.

# Reference SDK Check

When implementing SDK features or debugging provider-specific issues, check reference implementations.

## When to Use

- Implementing SDK features
- Debugging provider-specific issues
- Understanding how other libraries solve similar problems
- "How does Vercel AI SDK do X?"
- "Check Anthropic SDK for Y"

## Commands

Use `btca ask` to check how reference SDKs implement similar features:

```bash
# Check Vercel AI SDK for streaming patterns
btca ask -r vercel-ai -q "How does streamObject work?"

# Check Anthropic SDK for tool calling
btca ask -r anthropic-sdk -q "How are tools defined and called?"

# Check Zod for validation patterns
btca ask -r zod -q "How does safeParse handle errors?"
```

## Configured Resources

- `vercel-ai` - Streaming, tool calling, structured output
- `anthropic-sdk` - Anthropic API patterns
- `zod` - Schema validation

Add more: `btca config resources add -n <name> -t git -u <url> -b <branch>`

## When to Check

1. **Before implementing** - See how others solved similar problems
2. **When debugging** - Find how reference code handles edge cases
3. **Multi-provider support** - Compare implementations across SDKs
4. **Validation patterns** - Check idiomatic approaches

## Don't Use For

- Documentation lookups (use /nia-docs instead)
- Simple API questions (use WebSearch)
- Project-specific patterns (use Grep/Glob)
