PLANNER ONLY: Reset the coordination session for a fresh start. Clears all tasks, locks, notes, and archives discussions. Use this when starting a new project or when data from previous sessions is cluttering the dashboard.
AI agents call session_reset to permanently remove resources in Lockstep — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly deletes or overwrites data: it clears all tasks, locks, notes, and archives discussions in a coordination session. These are not reversible operations within the tool's scope—once cleared, recovery would require external backups. This is an irreversible destructive action affecting shared state across multiple coordinated agents, making it more severe than Write (which modifies reversibly).

Attacks that exploit this kind of access
PLANNER ONLY: Reset the coordination session for a fresh start. Clears all tasks, locks, notes, and archives discussions. Use this when starting a new project or when data from previous sessions is cluttering the dashboard. It is categorised as a Destructive tool in the Lockstep MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Lockstep MCP server in PolicyLayer and add a rule for session_reset: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Lockstep. Nothing to install.
session_reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the session_reset rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for session_reset. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
session_reset is provided by the Lockstep MCP server (tmmoore286/lockstep-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
