Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.01733 |
| Opus 5.5 | $0.00026 | $0.00693 |
| Sonnet 5.5 | $0.00013 | $0.00347 |
| Haiku 4.5 | $0.00006 | $0.00173 |
Grade A, and why
claude-agent-sdk-python scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Basic Patterns
One-Shot Query
import anyio
from claude_agent_sdk import query, AssistantMessage, TextBlock, ResultMessage
async def main():
async for msg in query(prompt="Explain Python decorators"):
if isinstance(msg, AssistantMessage):
for block in msg.content:
if isinstance(block, TextBlock):
print(block.text)
elif isinstance(msg, ResultMessage):
print(f"Cost: ${msg.total_cost_usd:.4f}")
anyio.run(main)
Interactive Client
import anyio
from claude_agent_sdk import (
ClaudeSDKClient,
ClaudeAgentOptions,
AssistantMessage,
TextBlock,
ResultMessage,
)
async def main():
options = ClaudeAgentOptions(
system_prompt="You are a helpful assistant",
allowed_tools=["Read", "Write", "Bash"],
permission_mode="acceptEdits",
max_turns=10,
)
async with ClaudeSDKClient(options=options) as client:
await client.query("Analyze main.py")
async for msg in client.receive_response():
if isinstance(msg, AssistantMessage):
for block in msg.content:
if isinstance(block, TextBlock):
print(block.text)
elif isinstance(msg, ResultMessage):
print(f"Done. Cost: ${msg.total_cost_usd:.4f}")
anyio.run(main)
Custom Tools
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claude-agent-sdk-python is a skill published in the GitHub repository kivo360/OmoiOS (81 stars, last pushed 14d ago), licensed Apache-2.0. It adds 65 tokens to every session and 1,733 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
