* fix(ci): resolve all CI failures — unversioned integrations, test retries - Move integration docs to separate unversioned docs plugin (docs-integrations/) so new integrations don't need to be duplicated across versioned_docs - Remove integration pages from versioned_docs (v0.3, v0.4) — sidebar entries now use links instead of doc refs - Add missing title/description SEO frontmatter to autogen.md - Add retry logic (2 attempts) to test-doc-examples.sh for transient LLM timeouts - Add pytest-rerunfailures to test-api with --reruns 2 for flaky Gemini-dependent integration tests * ci: retrigger * fix: graph entity inheritance, SyncTaskBackend error propagation, fact_type test regressions - Fix observation entity inheritance in get_graph_data: the unit_entities query only fetched entities for visible observation IDs, not their source memory IDs, so the inheritance loop always found an empty entity_map - Remove error swallowing in SyncTaskBackend._execute_task so test failures surface instead of being silently logged - Wrap remaining consolidation submission call sites with try/except since consolidation is non-critical for those operations - Fix test_sync_backend test to expect errors to propagate - Remove fact_type=["world"] filter from test_document_upsert_behavior and test_mentioned_at_from_context_string (same PR #848 regression) - Remove flaky marker from consolidation test (now deterministic)

# Strands Agents
|
|
|
|
Persistent memory tools for [Strands Agents SDK](https://github.com/strands-agents/sdk-python) agents via Hindsight. Give your agents long-term memory with retain, recall, and reflect — using Strands' native `@tool` pattern.
|
|
|
|
## Features
|
|
|
|
- **Native `@tool` Functions** - Tools are plain Python functions, compatible with `Agent(tools=[...])`
|
|
- **Memory Instructions** - Pre-recall memories for injection into agent system prompt
|
|
- **Three Memory Tools** - Retain (store), Recall (search), Reflect (synthesize) — include any combination
|
|
- **Simple Configuration** - Configure once globally, or pass a client directly
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
pip install hindsight-strands
|
|
```
|
|
|
|
## Quick Start
|
|
|
|
```python
|
|
from strands import Agent
|
|
from hindsight_strands import create_hindsight_tools
|
|
|
|
tools = create_hindsight_tools(
|
|
bank_id="user-123",
|
|
hindsight_api_url="http://localhost:8888",
|
|
)
|
|
|
|
agent = Agent(tools=tools)
|
|
agent("Remember that I prefer dark mode")
|
|
agent("What are my preferences?")
|
|
```
|
|
|
|
The agent now has three tools it can call:
|
|
|
|
- **`hindsight_retain`** — Store information to long-term memory
|
|
- **`hindsight_recall`** — Search long-term memory for relevant facts
|
|
- **`hindsight_reflect`** — Synthesize a reasoned answer from memories
|
|
|
|
## With Memory Instructions
|
|
|
|
Pre-recall relevant memories and inject them into the system prompt:
|
|
|
|
```python
|
|
from hindsight_strands import create_hindsight_tools, memory_instructions
|
|
|
|
tools = create_hindsight_tools(
|
|
bank_id="user-123",
|
|
hindsight_api_url="http://localhost:8888",
|
|
)
|
|
|
|
memories = memory_instructions(
|
|
bank_id="user-123",
|
|
hindsight_api_url="http://localhost:8888",
|
|
)
|
|
|
|
agent = Agent(
|
|
tools=tools,
|
|
system_prompt=f"You are a helpful assistant.\n\n{memories}",
|
|
)
|
|
```
|
|
|
|
## Selecting Tools
|
|
|
|
Include only the tools you need:
|
|
|
|
```python
|
|
tools = create_hindsight_tools(
|
|
bank_id="user-123",
|
|
hindsight_api_url="http://localhost:8888",
|
|
enable_retain=True,
|
|
enable_recall=True,
|
|
enable_reflect=False, # Omit reflect
|
|
)
|
|
```
|
|
|
|
## Global Configuration
|
|
|
|
Instead of passing connection details to every call, configure once:
|
|
|
|
```python
|
|
from hindsight_strands import configure, create_hindsight_tools
|
|
|
|
configure(
|
|
hindsight_api_url="http://localhost:8888",
|
|
api_key="your-api-key", # Or set HINDSIGHT_API_KEY env var
|
|
budget="mid", # Recall budget: low/mid/high
|
|
max_tokens=4096, # Max tokens for recall results
|
|
tags=["env:prod"], # Tags for stored memories
|
|
recall_tags=["scope:global"], # Tags to filter recall
|
|
recall_tags_match="any", # Tag match mode: any/all/any_strict/all_strict
|
|
)
|
|
|
|
# Now create tools without passing connection details
|
|
tools = create_hindsight_tools(bank_id="user-123")
|
|
```
|
|
|
|
