AI agents call abandon to permanently remove resources in Jj — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Abandoning revisions in a version control system irreversibly discards commits and their changes, rebasing descendants. While jj is designed with some recovery mechanisms, the intent and primary effect is to permanently remove revisions from the working history, making this a Destructive operation with high severity due to potential loss of work.

Parameters: revisions (Revisions to abandon, e.g.,. It is categorised as a Destructive tool in the Jj MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Jj MCP server in PolicyLayer and add a rule for abandon: 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 Jj. Nothing to install.
abandon 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 abandon 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 abandon. 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.
abandon is provided by the Jj MCP server (jj-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
