Claim Types

Claim	Description	Example
role	Agent role in swarm	coordinator, worker, reviewer
scope	Permitted operations	read, write, execute, admin
context	Execution context	swarm:123, task:456
capability	Specific capability	file_write, bash_execute, memory_store
resource	Resource access	memory:patterns, mcp:tools

Authorization Commands

# Check if agent has permission
npx claude-flow@v3alpha claims check \
  --agent "agent-123" \
  --resource "memory:patterns" \
  --action "write"

# Grant claim to agent
npx claude-flow@v3alpha claims grant \
  --agent "agent-123" \
  --claim "scope:write" \
  --resource "memory:*"

# Revoke claim
npx claude-flow@v3alpha claims revoke \
  --agent "agent-123" \
  --claim "scope:admin"

# List agent claims
npx claude-flow@v3alpha claims list --agent "agent-123"

Policy Definitions

Role-Based Policies

# coordinator-policy.yaml
role: coordinator
claims:
  - scope:read
  - scope:write
  - scope:execute
  - capability:agent_spawn
  - capability:task_orchestrate
  - capability:memory_admin
  - resource:swarm:*
  - resource:agents:*
  - resource:tasks:*

# worker-policy.yaml
role: worker
claims:
  - scope:read
  - scope:write
  - capability:file_write
  - capability:bash_execute
  - resource:memory:own
  - resource:tasks:assigned

Attribute-Based Policies

# security-agent-policy.yaml
conditions:
  - agent.type == "security-architect"
  - agent.verified == true
claims:
  - scope:admin
  - capability:security_scan
  - capability:cve_check
  - resource:security:*

MCP Tool Authorization

Protected MCP tools require claims:

Tool	Required Claims
swarm_init	scope:admin, capability:swarm_create
agent_spawn	scope:execute, capability:agent_spawn
memory_usage	scope:read|write, resource:memory:*
security_scan	scope:admin, capability:security_scan
neural_train	scope:write, capability:neural_train

Hook Integration

Claims are checked automatically via hooks:

{
  "PreToolUse": [{
    "matcher": "^mcp__claude-flow__.*$",
    "hooks": [{
      "type": "command",
      "command": "npx claude-flow@v3alpha claims check --agent $AGENT_ID --tool $TOOL_NAME --auto-deny"
    }]
  }],
  "PermissionRequest": [{
    "matcher": ".*",
    "hooks": [{
      "type": "command",
      "command": "npx claude-flow@v3alpha claims evaluate --request '$PERMISSION_REQUEST'"
    }]
  }]
}

Audit Logging

All authorization decisions are logged:

# Store authorization decision
mcp__claude-flow__memory_usage --action="store" \
  --namespace="audit" \
  --key="auth:$(date +%s)" \
  --value='{"agent":"agent-123","resource":"memory:patterns","action":"write","decision":"allow","reason":"has scope:write claim"}'

# Query audit log
mcp__claude-flow__memory_search --pattern="auth:*" --namespace="audit" --limit=100

Default Policies

Agent Type	Default Claims
coordinator	Full swarm access
coder	File write, bash execute
tester	File read, test execute
reviewer	File read, comment write
security-*	Security scan, CVE check
memory-*	Memory admin

Error Handling

// Authorization denied response
{
  "authorized": false,
  "reason": "Missing required claim: scope:admin",
  "required_claims": ["scope:admin", "capability:swarm_create"],
  "agent_claims": ["scope:read", "scope:write"],
  "suggestion": "Request elevation or use coordinator agent"
}
