raysurfer 0.6.7

Semantic code caching for LLM agents

RaySurfer Python SDK

Drop-in replacement for Claude Agent SDK with automatic code caching.

Installation

pip install raysurfer

Setup

Set your API key:

export RAYSURFER_API_KEY=your_api_key_here

Get your key from the dashboard.

Usage

Swap your client class and method names. Options come directly from claude_agent_sdk:

# Before
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

# After
from raysurfer import RaysurferClient
from claude_agent_sdk import ClaudeAgentOptions

options = ClaudeAgentOptions(
    allowed_tools=["Read", "Write", "Bash"],
    system_prompt="You are a helpful assistant.",
)

async with RaysurferClient(options) as client:
    await client.query("Generate quarterly report")
    async for msg in client.response():
        print(msg)

Method Mapping

Claude SDK	Raysurfer
ClaudeSDKClient(options)	RaysurferClient(options)
await client.query(prompt)	await client.query(prompt)
client.receive_response()	client.response()

How It Works

1. On query(): Retrieves cached code blocks matching your task
2. Downloads to sandbox: Files ready for the agent to execute
3. Injects into prompt: Agent sees proven code snippets
4. After success: New code is cached for next time

Caching is enabled automatically when RAYSURFER_API_KEY is set.

Snippet Retrieval Scope

Control which cached snippets are retrieved using snips_desired:

from raysurfer import RaysurferClient
from claude_agent_sdk import ClaudeAgentOptions

options = ClaudeAgentOptions(
    allowed_tools=["Read", "Write", "Bash"],
)

# Include company-level snippets
client = RaysurferClient(
    options,
    snips_desired="company",  # Company-level snippets (Team/Enterprise)
)

# Enterprise: Retrieve client-specific snippets only
client = RaysurferClient(
    options,
    snips_desired="client",   # Client workspace snippets (Enterprise only)
)

Configuration	Required Tier
snips_desired="company"	TEAM or ENTERPRISE
snips_desired="client"	ENTERPRISE only

Full Example

import asyncio
import os
from raysurfer import RaysurferClient
from claude_agent_sdk import ClaudeAgentOptions

os.environ["RAYSURFER_API_KEY"] = "your_api_key"

async def main():
    options = ClaudeAgentOptions(
        allowed_tools=["Read", "Write", "Bash"],
        system_prompt="You are a helpful assistant.",
    )

    async with RaysurferClient(options) as client:
        # First run: generates and caches code
        await client.query("Fetch GitHub trending repos")
        async for msg in client.response():
            print(msg)

        # Second run: retrieves from cache (instant)
        await client.query("Fetch GitHub trending repos")
        async for msg in client.response():
            print(msg)

asyncio.run(main())

Without Caching

If RAYSURFER_API_KEY is not set, RaysurferClient behaves exactly like ClaudeSDKClient — no caching, just a pass-through wrapper.

Low-Level API

For custom integrations, use the RaySurfer client directly with three core methods:

from raysurfer import RaySurfer
from raysurfer.types import FileWritten, LogFile

client = RaySurfer(api_key="your_api_key")

# 1. Get cached code snippets for a task
snips = client.get_code_snips(task="Fetch GitHub trending repos")
for match in snips.code_blocks:
    print(f"{match.code_block.name}: {match.score}")

# Or use the unified search endpoint
search_result = client.search(task="Fetch GitHub trending repos")
for match in search_result.matches:
    print(f"{match.code_block.name}: {match.combined_score}")

# 2. Upload a new code file after execution
file = FileWritten(path="fetch_repos.py", content="def fetch(): ...")
client.upload_new_code_snip(
    task="Fetch GitHub trending repos",
    file_written=file,
    succeeded=True,
)

# 2b. Bulk upload prompts/logs/code for sandboxed grading
logs = [LogFile(path="logs/run.log", content="Task completed", encoding="utf-8")]
client.upload_bulk_code_snips(
    prompts=["Build a CLI tool", "Add CSV support"],
    files_written=[FileWritten(path="cli.py", content="def main(): ...")],
    log_files=logs,
    auto_vote=True,
)

# 3. Vote on whether a cached snippet was useful
client.vote_code_snip(
    task="Fetch GitHub trending repos",
    code_block_id="abc123",
    code_block_name="github_fetcher",
    code_block_description="Fetches trending repos from GitHub",
    succeeded=True,
)

Async Version

from raysurfer import AsyncRaySurfer
from raysurfer.types import FileWritten

async with AsyncRaySurfer(api_key="your_api_key") as client:
    snips = await client.get_code_snips(task="Fetch GitHub trending repos")

    file = FileWritten(path="fetch_repos.py", content="def fetch(): ...")
    await client.upload_new_code_snip(
        task="Fetch GitHub trending repos",
        file_written=file,
        succeeded=True,
    )

    await client.vote_code_snip(
        task="Fetch GitHub trending repos",
        code_block_id=snips.code_blocks[0].code_block.id,
        code_block_name=snips.code_blocks[0].code_block.name,
        code_block_description=snips.code_blocks[0].code_block.description,
        succeeded=True,
    )

Method Reference

Method	Description
search(task, top_k, min_verdict_score, prefer_complete)	Unified search for cached code (recommended)
get_code_snips(task, top_k, min_verdict_score)	Retrieve cached code snippets by semantic search
upload_new_code_snip(task, file_written, succeeded)	Store a single code file for future reuse
upload_bulk_code_snips(prompts, files_written, log_files, auto_vote)	Bulk upload prompts/logs/code for sandboxed grading
vote_code_snip(task, code_block_id, name, description, succeeded)	Vote on snippet usefulness
