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 3d 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.

Origin

This is a copy

89% identical to forget — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

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. Report the deletion count back.

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.

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.
