forget

A controlled routine for deleting selected notes from an agent's memory after showing them and getting explicit confirmation.

In plain words
What is it for?
It helps find matching memories, confirm exactly what will be removed, and delete selected observations or lessons.
Why use it?
It reduces the risk of accidentally erasing information and supports privacy requests by deleting specific memory records rather than an entire session.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

forget scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The user wants to remove data from agentmemory: $ARGUMENTS

Quick start

memory_smart_search { "query": "old api key in config", "limit": 20 }

Show the matches, get a yes, then:

memory_governance_delete { "memoryIds": ["abc12345", "def67890"], "reason": "user privacy request" }

Expected output:

Found 2 matching memories. Confirmed. Deleted 2 memories.

Why

This is destructive and irreversible. Show exactly what will be deleted and get an explicit yes before calling delete. Delete by memory ID, never a bare session.

Workflow

  1. Search with memory_smart_search, the user's text as query, limit: 20.
  2. Show what matched: session ids, memory ids, titles. Ask for explicit confirmation. Do not proceed on silence or a vague "sure, whatever".
  3. On confirmation, call memory_governance_delete with memoryIds (array or comma-separated string) and optional reason (default plugin skill request).
  4. To drop a whole session, collect every memory id in that session from the search results and pass them all. The MCP does not accept a bare sessionId.
  5. Lessons are separate: delete one with memory_lesson_delete and its lessonId; memory_governance_delete does not touch lessons.
  6. Report the deletion count back. A count of 0 means the ids did not exist; say so instead of claiming a delete.

Anti-patterns

WRONG: search returns matches, you immediately call memory_governance_delete without showing them or waiting for a yes.

RIGHT: list the matches, ask "Delete these 2? (yes/no)", and only delete after an explicit yes.

Checklist

  • Matches were shown to the user before any delete.
  • An explicit yes was received, not assumed.
  • memoryIds holds real ids from the search, never a bare sessionId.
  • Final message states the actual count deleted.

See also

  • remember: the write side; forget is its undo.
  • recall: find the exact memory id before deleting.

Troubleshooting

See ../_shared/TROUBLESHOOTING.md if memory_smart_search or memory_governance_delete is not available.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

forget is a skill published in the GitHub repository rohitg00/agentmemory (27,906 stars, last pushed 2d ago), licensed Apache-2.0. It adds 43 tokens to every session and 595 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
