At a glance

Deletes Mem0 memories found by search query or memory ID, listing the matches and requiring explicit confirmation before anything is removed.

  • Works in 5 steps: Parse input → Find memories → Confirm → …
  • Removing outdated or incorrect memories
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Deleting sensitive information that was stored in memory

What it does

The skill takes either a search query or a memory ID through /mem0-forget and asks what to forget if you give neither. For an ID, it looks the memory up and shows the start of its content with the created date. For a query, it searches and shows a numbered list of matches with their category and short ID.

Before deleting anything, it asks which memories to remove, accepting numbers, all or cancel, or a yes or no for a single ID, and it states that nothing is deleted without confirmation because deletion is destructive. Each confirmed memory is removed through the mem0_memory tool, and the agent reports how many were deleted along with any failures and their reasons.

When your agent uses it

  • Removing outdated or incorrect memories
  • Deleting sensitive information that was stored in memory
  • Cleaning up memories left behind by an experiment

Example prompts

  • “Forget everything we stored about the old staging database.”
  • “Find the memories about my travel plans and let me pick which ones to delete.”
  • “Clean up the memories from yesterday's experiment, and ask me before deleting anything.”

Requirements

  • The mem0_memory tool, used here for search and delete

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Parse input
  2. Find memories
  3. Confirm
  4. Delete
  5. Report

What it can do on your machine

Read from SKILL.md and the folder at commit b7ad69a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mem0 Forget loads about 360 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 153 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~360

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Deletes memories by search query or memory ID with confirmation before removal. Use when removing outdated information, incorrect memories, sensitive data, or cleaning up after experiments.

Forget

Delete specific memories from Mem0.

Execution

Step 1: Parse input

The user provides either:

  • A search query: /mem0-forget travel plans
  • A memory ID: /mem0-forget <memory_id>

If no argument, ask: "What should I forget? Provide a search query or memory ID."

Step 2: Find memories

If memory ID provided (looks like a UUID or hex string):

  • Use mem0_memory tool with action="search" and the ID as query, or look it up directly.
  • Show: Found: "<memory content first 120 chars>" (created <date>)

If search query provided:

  • Use mem0_memory tool with action="search", query=<user's query>.
  • Show numbered list:
    Found <N> memories matching "<query>":
    1. <content, 120 chars> [<category>] [ID: <short_id>]
    2. ...
Step 3: Confirm

Ask: "Delete which memories? Enter numbers (e.g., 1,3,5), 'all', or 'cancel'."

For a single memory ID, ask: "Delete this memory? [y/N]"

Never delete without confirmation. This is destructive.

Step 4: Delete

For each confirmed memory, use mem0_memory tool with action="delete" and the memory ID.

Step 5: Report
Deleted <N> memories.

If any deletions failed, report which ones and why.
