Here I Strand

Library that provides a Strands agent for AWS Bedrock Agent Core with DynamoDB status tracking, S3 session persistence, and a concurrent tool executor with per-tool timeouts (HIS: here-i-strand).

Repository: github.com/tisaarus/here-i-strand

Installation

pip install here-i-strand
# or with uv
uv add here-i-strand

Quick start

You define how to load configuration (environment variables, your own settings module, etc.) and pass the values to HISAgent:

import os
from his import HISAgent

agent = HISAgent(
    bucket_name=os.environ["BUCKET_NAME"],
    status_dynamo_table_name=os.environ["STATUS_DYNAMO_TABLE_NAME"],
    session_id="my-session-id",
    name=os.environ.get("AGENT_NAME", "my-agent"),
    tools=[...],
)

Configuration

The library does not provide a settings layer. Pass bucket_name, status_dynamo_table_name, session_id, and optionally name (and any other HISAgent arguments) from your own config:

• Environment variables
• A .env file loaded by your app (e.g. python-dotenv, pydantic-settings)
• Any other configuration source you use

Main components

• HISAgent: Strands agent with a DynamoDB ping thread and S3 sessions. You pass status_dynamo_table_name, bucket_name, session_id, and optionally name so the ping and tracker use your table and bucket.
• TimeoutConcurrentToolExecutor: Tool executor with a per-invocation timeout; if a tool exceeds the limit, an error is returned and execution continues with the rest.
• event_loop_tracker: Callback that writes event-loop milestones (init, start, message, result, force_stop) to DynamoDB and stops the ping when done.

Tests

uv sync --all-groups
uv run pytest tests/ -v
