# Cognee

Use this skill for **Cognee-specific Python API help** and for mapping user goals to the right Cognee workflow.

## When to apply this skill

Apply this skill whenever the user wants to do any of the following with Cognee:

- ingest text, files, URLs, repos, or datasets
- build or rebuild a knowledge graph
- search documents, chunks, summaries, triplets, or graph context
- choose a `SearchType`
- enrich an existing graph with `memify`
- define custom graph extraction models or `DataPoint` types
- run custom task pipelines
- configure LLM, graph DB, vector DB, or storage settings
- tag and scope memory with `node_set` / NodeSets
- build persistent memory for agents across sessions
- create feedback loops or self-improving agent workflows
- work with temporal extraction, ontologies, Cypher, or natural-language graph queries
- manage datasets, sessions, feedback, pruning, updates, or visualization

If the user’s intent is “store information in memory and query it later,” prefer Cognee’s core flow:
**add -> cognify -> search**

## Core workflow

```python
import cognee
from cognee import SearchType

await cognee.add(
    "Your text, file path, URL, or list of inputs",
    dataset_name="main",
    node_set=["default_memory"],
)
await cognee.cognify(datasets="main")
results = await cognee.search(
    "What are the key insights?",
    query_type=SearchType.GRAPH_COMPLETION,
    datasets="main",
)
```

## Default guidance

When helping with Cognee:

1. Start with the **simplest working path** unless the user explicitly asks for advanced configuration.
2. Prefer the standard workflow:
   - `add(...)` to ingest
   - `cognify(...)` to build the graph
   - `search(...)` to query it
3. Treat Cognee APIs as **async**.
4. Use `dataset_name` / `datasets` to keep work organized when the user has multiple sources.
5. Use `node_set` when the user wants lightweight tagging, project scoping, per-user memory buckets, or subgraph filtering.
6. Recommend advanced features only when they match the task:
   - `memify(...)` for enriching an existing graph
   - `temporal_cognify=True` for time-aware extraction
   - custom graph models or `DataPoint` types for domain-specific extraction
   - custom pipelines for non-default task orchestration
   - feedback loops for retrieval improvement
   - visualization tools for graph inspection

## Common tasks

### Add data

Use `cognee.add(...)` for text, files, URLs, or mixed inputs.

```python
await cognee.add("notes.md", dataset_name="research")
await cognee.add("https://example.com", dataset_name="research")
await cognee.add(["paper.pdf", "summary.txt"], dataset_name="research")
```

Use `node_set` when the user wants data grouped into logical memory buckets.

```python
await cognee.add(
    "Customer prefers concise weekly summaries and Slack delivery.",
    dataset_name="customer_success",
    node_set=["preferences", "customer_123", "weekly_reports"],
)
```

### Build the graph

Use `cognee.cognify(...)` after ingestion.

```python
await cognee.cognify(datasets="research")
```

Use these options when relevant:

```python
await cognee.cognify(
    datasets="research",
    temporal_cognify=True,
    chunk_size=1024,
    custom_prompt="Extract companies, products, and partnerships.",
)
```

### Search the graph

Use `cognee.search(...)` and pick the search mode that matches the request.

```python
results = await cognee.search(
    "What changed in Q1 2024?",
    query_type=SearchType.TEMPORAL,
    datasets="research",
    top_k=10,
)
```

### Scope search with NodeSets

Use NodeSets when the user wants to search only a subset of memory such as one project, one customer, one user, or one workflow.

```python
results = await cognee.search(
    query_text="What are this customer's reporting preferences?",
    query_type=SearchType.GRAPH_COMPLETION,
    datasets="customer_success",
    node_name=["preferences", "customer_123"],
)
```

### Enrich an existing graph

Use `memify(...)` when the user wants to improve or extend an already-built graph without restarting the full workflow.

```python
await cognee.memify(dataset="research")
```

### Create domain-specific structures

Use custom models when the user wants extraction shaped around a schema.

```python
from typing import Any
from pydantic import SkipValidation
from cognee.infrastructure.engine import DataPoint
from cognee.tasks.storage import add_data_points

class ScientificPaper(DataPoint):
    title: str
    authors: list[str]
    methodology: str
    findings: list[str]
    cites: SkipValidation[Any] = None
    metadata: dict = {"index_fields": ["title", "findings"]}

paper = ScientificPaper(
    title="Graph Memory for Agents",
    authors=["A. Researcher"],
    methodology="Knowledge graph + vector retrieval",
    findings=["Improved cross-session recall", "Better multi-hop retrieval"],
)

await add_data_points([paper])
```

### Run custom pipelines

Use `run_custom_pipeline(...)` when the user needs explicit sequential task control.

```python
from cognee.modules.pipelines.tasks.task import Task

async def my_task(data):
    return data

await cognee.run_custom_pipeline(
    tasks=[Task(my_task)],
    data="input",
    dataset="research",
)
```

## DataPoints

A `DataPoint` is the **atomic unit of knowledge** in Cognee.

Use this concept whenever the user asks how Cognee represents structured data internally or how to insert graph objects directly.

Key ideas:

- A `DataPoint` is a Pydantic model that represents one meaningful unit of information.
- It can carry both **content** and **context**, including indexing hints and relationship fields.
- When inserted directly, DataPoints can become graph nodes and edges while also contributing searchable vector fields.
- `metadata = {"index_fields": [...]}` controls which fields should be embedded for semantic search.
- Relationship fields can point to other DataPoints, letting you define graph structure programmatically.
- DataPoints are ideal when the user already has structured objects and does **not** want to rely only on text extraction.

Use `DataPoint` when the user wants:

- schema-shaped memory
- exact control over graph structure
- programmatic relationship creation
- custom domain entities such as papers, customers, incidents, policies, products, or workflows

Prefer plain `add(...) -> cognify(...)` for unstructured documents.
Prefer `DataPoint` models plus `add_data_points(...)` when the user already has structured Python objects and wants direct graph insertion.

## NodeSets

Use NodeSets when the user wants a lightweight way to **tag, group, and scope memory**.

A NodeSet starts as a simple list of tags passed through `node_set=[...]` during `add(...)`, but after `cognify()` those tags become first-class graph nodes that help organize retrieval.

### Why NodeSets matter

- They let the user organize memory by project, team, customer, workflow, topic, or environment.
- They make it easy to search only a relevant subgraph instead of the full dataset.
- They are especially useful in agent systems where one memory store contains many users, jobs, or tasks.

### Good NodeSet patterns

- per customer: `["customer_123"]`
- per workflow: `["support_bot", "refund_flow"]`
- per topic: `["contracts", "vendor_risk"]`
- per environment: `["prod", "staging"]`
- per user memory: `["user_42", "preferences"]`

### Example

```python
await cognee.add(
    [
        "Alice prefers terse answers and email follow-ups.",
        "Alice escalates billing issues to finance first.",
        "Bob prefers detailed technical explanations."
    ],
    dataset_name="agent_memory",
    node_set=["crm", "user_profiles"],
)

await cognee.cognify(datasets="agent_memory")

results = await cognee.search(
    query_text="How should I respond to Alice?",
    datasets="agent_memory",
    node_name=["crm", "user_profiles"],
)
```

Use NodeSets by default whenever the user says things like:

- “scope memory by customer”
- “separate projects without making separate databases”
- “let the agent search only its own memories”
- “group facts by workflow or team”

## SearchType selection guide

Use these defaults:

- `GRAPH_COMPLETION`: best default for graph-aware Q&A
- `RAG_COMPLETION`: traditional RAG over document chunks
- `CHUNKS`: fast semantic retrieval without completion
- `CHUNKS_LEXICAL`: exact-term / keyword matching
- `SUMMARIES`: overview of documents
- `TRIPLET_COMPLETION`: subject-predicate-object style graph Q&A
- `GRAPH_SUMMARY_COMPLETION`: graph + summary-based answers
- `GRAPH_COMPLETION_COT`: deeper reasoning over graph context
- `GRAPH_COMPLETION_CONTEXT_EXTENSION`: broader graph context retrieval
- `CYPHER`: raw Cypher queries when enabled
- `NATURAL_LANGUAGE`: natural language to graph query
- `TEMPORAL`: time-aware graph search
- `CODING_RULES`: code rules and patterns
- `CODE`: deterministic code fact lookup, graph traversal, paths, and impact analysis
- `FEELING_LUCKY`: let Cognee choose automatically
- `FEEDBACK`: apply feedback to improve later retrieval behavior

## Agentic workflows and feedback-driven improvement

Use Cognee as the **memory layer for agent systems** that need to improve over time through better recall, better reuse of prior work, and better retrieval of successful past behavior.

The key idea is simple:

- keep the **agent workflow itself constant**
- keep the **prompt and tools constant**
- change only what the agent can remember and retrieve

This means “improvement” comes from **memory reuse and retrieval quality**, not from changing the model or retraining it.

### What Cognee gives agentic workflows

Cognee helps agent systems:

- store observations, decisions, outcomes, and learned patterns as memory
- retrieve graph-aware context instead of relying only on flat chunk search
- reuse prior investigations, plans, and successful resolutions
- preserve short-term context through sessions
- consolidate useful session history into long-term knowledge
- scope memory by user, customer, workflow, team, or environment with datasets and NodeSets
- improve future behavior through feedback loops and memory enrichment

### The general feedback pattern

A strong way to explain Cognee in agent systems is:

1. **Baseline condition**
   The agent searches the existing knowledge graph and acts using only current stored knowledge.

2. **Feedback-enabled condition**
   The agent uses the same prompt and the same tools, but now benefits from:
   - **short-term memory** from cached or sessionized interactions
   - **long-term memory** created by periodically persisting useful sessions back into the graph

3. **Improvement mechanism**
   Future runs become faster or better because the agent can retrieve:
   - similar prior cases
   - successful resolutions
