On January 12, 2026, Anthropic introduced Cowork—a general-purpose AI agent experience built on the same foundations as Claude Code but designed for everyday knowledge work. While Claude Code targets developers, Cowork empowers business professionals to delegate complex, multi-step tasks like document drafting, file organization, research synthesis, and workflow automation. Combined with Anthropic’s newly published Claude Constitution (January 21, 2026), which defines the model’s values and behavioral guidelines, Cowork represents a significant step toward trustworthy, autonomous AI assistants in enterprise environments.
What is Cowork?
Cowork is Anthropic’s answer to the question: “What if Claude could do your work, not just answer your questions?” It transforms Claude from a conversational AI into an autonomous agent that can:
- Read and organize files: Access local files, categorize documents, extract key information
- Draft and edit documents: Create reports, proposals, emails based on context and templates
- Perform multi-step tasks: Chain together actions to accomplish complex workflows
- Manage research: Synthesize information from multiple sources into coherent summaries
- Automate repetitive work: Handle routine tasks with user-defined parameters
Critically, Cowork operates with explicit user consent at each step—you approve actions before execution, maintaining human oversight while benefiting from AI capabilities.

Cowork vs Claude Code
| Feature | Claude Code | Cowork |
|---|---|---|
| Target User | Software developers | Knowledge workers, business professionals |
| Primary Actions | Write, test, debug code | Documents, files, research, workflows |
| Environment | IDE, terminal, git | Desktop, browser, productivity tools |
| Autonomy Level | High (within sandbox) | Medium (approval-gated) |
| File Access | Code repositories | Documents, spreadsheets, presentations |
| Output | Working code, PRs | Documents, summaries, organized files |
The Claude Constitution
On January 21, 2026, Anthropic published the Claude Constitution—a detailed document defining Claude’s values, behavioral guidelines, and decision-making principles. This matters for Cowork because agents need clear ethical frameworks when acting autonomously.
Key Constitutional Principles
- Safety First: Never take actions that could harm users, organizations, or third parties
- Transparency: Always explain reasoning and potential consequences of actions
- User Authority: The user has final say; Claude advises but doesn’t override
- Minimal Footprint: Access only the resources needed for the current task
- Reversibility: Prefer actions that can be undone; warn before irreversible changes
- Privacy Preservation: Don’t access, store, or transmit data beyond task requirements
The Claude Constitution builds on Anthropic’s research in Constitutional AI (CAI), where models are trained to follow explicit principles rather than relying solely on RLHF. This makes behavior more predictable and auditable—essential for enterprise adoption.
Getting Started with Cowork
from anthropic import Anthropic
from anthropic.cowork import CoworkSession, Approval
# Initialize Cowork session
client = Anthropic()
session = CoworkSession(
client=client,
workspace_path="~/Documents/Projects/Q1-Report",
approval_mode="interactive" # or "auto" for pre-approved actions
)
# Define a complex task
task = """
Review the sales data files in this folder, create a summary report
highlighting Q1 performance vs targets, and draft an executive summary
email for the leadership team.
"""
# Execute with step-by-step approval
async for action in session.run(task):
print(f"
📋 Proposed Action: {action.description}")
print(f" Tool: {action.tool}")
print(f" Target: {action.target}")
if action.requires_approval:
# User reviews and approves
approval = await get_user_approval(action)
if approval == Approval.APPROVED:
result = await action.execute()
print(f" ✅ Result: {result.summary}")
elif approval == Approval.MODIFIED:
# User can modify the action
modified_action = await modify_action(action)
result = await modified_action.execute()
else:
print(f" ❌ Skipped by user")
continue
# Get final outputs
outputs = session.get_outputs()
print(f"
Generated {len(outputs)} documents")
for output in outputs:
print(f" - {output.name}: {output.path}")

# Configure session with specific tools

Enterprise Integration
Cowork launched with enterprise-grade features, including the ServiceNow partnership that deploys Claude to over 29,000 employees:
from anthropic.cowork.enterprise import EnterpriseCowork
# Enterprise configuration with SSO and audit logging
enterprise_session = EnterpriseCowork(
organization_id="org_abc123",
# Identity and access
identity_provider="azure_ad",
user_token=get_sso_token(),
# Policy controls
policies={
"max_file_size_mb": 50,
"allowed_file_types": [".pdf", ".docx", ".xlsx", ".pptx"],
"restricted_folders": ["/HR/Confidential", "/Finance/Payroll"],
"require_approval": ["file_delete", "email_send", "external_share"],
"auto_approve": ["file_read", "summarize", "draft"]
},
# Audit and compliance
audit_config={
"enabled": True,
"log_destination": "azure_log_analytics",
"include_content": False, # Log actions, not content
"retention_days": 365
},
# Data residency
data_residency="eu-west-1" # Keep data in EU
)
# Actions are logged for compliance
async for action in enterprise_session.run(task):
# Audit log automatically captures:
# - User identity
# - Action type and target
# - Timestamp
# - Approval status
# - Constitutional principle checks
result = await action.execute()
Cowork processes files locally when possible, sending only necessary context to Claude. For sensitive industries (healthcare, finance), configure local_processing_only=True to ensure PHI/PII never leaves your infrastructure.
Real-World Use Cases
1. Research Synthesis
task = """
Research the latest FDA guidance on AI-assisted diagnostics.
Compile findings from the past 6 months, identify key compliance
requirements, and create a briefing document for the regulatory team.
Include citations and highlight any deadlines.
"""
# Cowork will:
# 1. Search relevant FDA sources
# 2. Read and analyze guidance documents
# 3. Extract key requirements and dates
# 4. Draft briefing with proper citations
# 5. Organize supporting documents in a folder
2. Quarterly Report Automation
task = """
Using the data in /Finance/Q4-2025/:
1. Analyze revenue by region and product line
2. Calculate YoY growth rates
3. Create charts for the board presentation
4. Draft the executive summary section
5. Identify any metrics that missed targets and suggest explanations
"""
# Cowork will request approval before:
# - Accessing financial data
# - Creating visualization files
# - Writing to the presentation template
3. Email and Document Management
task = """
Review my inbox for the past week. Categorize emails by priority
(urgent, normal, archive). For urgent items, draft response
suggestions. Summarize any action items and add them to my task list.
"""
# Approval flow:
# ✓ Read emails (auto-approved via policy)
# ✓ Categorize (auto-approved)
# ⚠️ Draft responses (requires approval)
# ✓ Create summary (auto-approved)
# ⚠️ Send responses (requires approval)
Best Practices
| Practice | Recommendation |
|---|---|
| Start Small | Begin with read-only tasks, gradually enable write actions |
| Define Policies | Configure auto-approve for safe actions, require approval for risky ones |
| Restrict Scope | Limit folder access to relevant workspaces only |
| Audit Everything | Enable comprehensive logging for compliance and debugging |
| Template Guidance | Provide templates and style guides for consistent outputs |
| Human Review | Always review generated documents before external sharing |
Key Takeaways
