What it does
Reference SDK is an agent skill from parcadei/Continuous-Claude-v3. Check reference SDK implementations using btca ask
Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering. It works with Anthropic API. The repository describes itself as: Context management for Claude Code. Hooks maintain state via ledgers and handoffs. MCP execution without context pollution. Agent orchestration with isolated context windows. The licence is MIT.
When your agent uses it
- AI & LLM Engineering work in your project
Example prompts
- “/reference-sdk”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Before implementing - See how others solved similar problems
- When debugging - Find how reference code handles edge cases
- Multi-provider support - Compare implementations across SDKs
- Validation patterns - Check idiomatic approaches
What it can do on your machine
Read from SKILL.md and the folder at commit d07ff4b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Reference SDK loads about 376 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 135 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:
# 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 outputanthropic-sdk- Anthropic API patternszod- Schema validation
Add more: btca config resources add -n <name> -t git -u <url> -b <branch>
When to Check
- Before implementing - See how others solved similar problems
- When debugging - Find how reference code handles edge cases
- Multi-provider support - Compare implementations across SDKs
- 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)

Check reference SDK implementations using btca ask. An agent skill from parcadei/Continuous-Claude-v3. Reference SDK is an agent skill from parcadei/Continuous-Claude-v3.
When should I use Reference SDK?
Reference SDK fits situations like: AI & LLM Engineering work in your project.
How do I install Reference SDK in Claude Code?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a claude-code`. Or copy the skill folder (.claude/skills/reference-sdk in parcadei/Continuous-Claude-v3) into .claude/skills/reference-sdk in your project. Claude Code loads it when a task matches its description.
How do I install Reference SDK in Codex?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a codex`. Or copy the skill folder (.claude/skills/reference-sdk in parcadei/Continuous-Claude-v3) into .agents/skills/reference-sdk in your project. Codex loads it when a task matches its description.
Can I use Reference SDK in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add parcadei/Continuous-Claude-v3 --skill reference-sdk -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/reference-sdk, .gemini/skills/reference-sdk, .github/skills/reference-sdk and .opencode/skills/reference-sdk in your project.
What does Reference SDK need to run?
SKILL.md names no scripts, command-line tools or credentials: Reference SDK is instructions for the agent only.
Does Reference SDK access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
