sac-agent 0.1.0

sac — Search as Code: agentic search orchestration using LLMs.

Install

pip install sac
uv pip install sac-agent

Usage

from sac import AgenticSearchSDK, SaCAgent

sdk = AgenticSearchSDK()
agent = SaCAgent(task="Research the latest AI papers on retrieval-augmented generation", sdk=sdk)
answer = agent.run()
print(answer)

CLI

sac "What are the latest developments in LLM agents?"
sac -v "Verbose research mode"
sac --endpoint https://opencode.ai/zen/v1 --model big-pickle "task"
sac --final-report ./report.md "task"
sac --final-report-format json --final-report ./output "task"
sac  # interactive mode

API

• AgenticSearchSDK — Composable SDK with search, llm, fs, utils attributes
• SaCAgent — Multi-turn research agent that generates and executes search code
• SearchSDK — Web search via Exa MCP (free) or Brave Search API
• LLMSDKClient — LLM integration via OpenAI-compatible API
• FilesystemSDK — Persistent key-value store
• UtilsSDK — Deduplication, filtering, flattening, coverage summarization
• Sandbox — Executes generated Python code in a restricted namespace

Code Library

Every code snippet the agent generates can be saved as a reusable, callable function with --with-code-library:

sac --with-code-library "Research the latest AI papers"

Functions are grouped by concern into ~/.cache/sac-agent/library/ (classification priority: extraction > synthesis > search > storage > analysis > pipeline):

Execution flow:

CLI (sac "task")
  → SaCAgent.run()
    → _call_model()                   # LLM generates JSON with "code"
    → sandbox.execute(code)           # exec() in restricted namespace
    → if successful: library.collect()  # save snippet in memory
    → repeat up to 6 turns
    → on synthesis: library.flush_all()
      → _classify_code() per snippet  # extraction > synthesis > search > ...
      → append to category file       # search.py / extraction.py / pipeline.py

Each function accepts sdk as its first parameter and has a Google-style docstring:

def search_fanout(sdk, queries, limit_per_query=5, concurrency=3):
    """Execute parallel searches across multiple queries and flatten results.

    Args:
        sdk: AgenticSearchSDK instance
        queries: List of search query strings
        limit_per_query: Results per query (default: 5)
        concurrency: Number of parallel workers (default: 3)

    Returns:
        Flattened list of SearchResult objects
    """
    results = sdk.search.web_many(queries, ...)
    return sdk.utils.flatten(results)

Load functions by name at runtime:

from sac.library import load_function

fn = load_function("search_fanout_1234")
results = fn(sdk)
