name: policy description: Views or sets the project's memory-extraction policy (what Mem0 remembers vs ignores) stored in mem0.md. Use when the user says set a memory policy, custom instructions, what should mem0 remember, tell mem0 to ignore X, or asks to see/change the current instructions.

Mem0 Policy

The project's memory policy lives in a ## Instructions section of mem0.md at the repo root. It is version-controlled and shared by the whole team, and it maps to Mem0's custom_instructions (what to extract / ignore). An optional ## Agent Instructions section maps to agent_custom_instructions (guidance for agent-scoped memories only).

The policy takes effect on the next session (mem0.md is re-parsed on SessionStart) and is applied automatically on the plugin's memory writes.

Execution

Step 1: Determine intent from the argument

/mem0:policy is invoked as /mem0:policy [<subcommand>] <text>:

| Argument | Action | |---|---| | (none) or show | Show the current policy | | set <text> or free text | Set/replace the ## Instructions (custom) policy | | agent <text> | Set/replace the ## Agent Instructions policy | | clear | Remove both policy sections |

Step 2: Locate mem0.md

mem0.md sits at the repo root (the current working directory). If it does not exist yet and the user is setting a policy, you will create it.

Step 3a: Show

Run python3 "$CLAUDE_PLUGIN_ROOT/scripts/parse_mem0_config.py" --key instructions . and --key agent_instructions . (or read mem0.md directly). Print:

Memory policy for this project (mem0.md):
  Instructions:       <text, or "(none)">
  Agent Instructions: <text, or "(none)">

If mem0.md is absent, say there is no policy yet and offer to set one.

Step 3b: Set / clear

Edit mem0.md, adding or replacing the target section. Keep the instruction a short prose paragraph (what to remember, what to ignore). Example:

## Instructions
Remember architecture decisions, API contracts, and team conventions.
Ignore transient debugging output, stack traces, and anything resembling a secret.

• Preserve any other existing sections (## Retention, ## Categories, etc.).
• If the section already exists, replace its body; otherwise append the section.
• For clear, delete the ## Instructions and ## Agent Instructions sections.

Step 4: Confirm

Updated memory policy in mem0.md.
Takes effect next session. Commit mem0.md to share it with your team.

Remind the user that ## Agent Instructions only affects agent-scoped memories, so it is a no-op unless memories are written with an agent_id.
