forget

forget is a skill for Claude Code from ThinkfleetAI/memmesh. It costs 73 tokens per session (416 once invoked), scanned A, original, Apache-2.0.

A tool for removing, undoing, or correcting information stored in MemMesh, a memory system for coding agents. It asks for confirmation and normally hides deleted items without erasing their history.

In plain words
What is it for?
Removing a saved memory, undoing a recent save, or replacing an old fact with a corrected one.
Why use it?
It prevents outdated, incorrect, or sensitive information from continuing to affect future answers. Corrections can keep a record of what changed.

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 1mo 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.

What it actually says

forget

Remove or correct what's in memory. Always confirm before deleting.

1. Find it

{ "name": "memory_search", "arguments": { "query": "<what to forget>", "projectId": "<repo>", "limit": 10 } }

Show the matches (id + content) and ask which to remove.

2. Delete

{ "name": "memory_delete", "arguments": { "id": "<id>" } }          // soft: status→rejected, sync-safe
{ "name": "memory_delete", "arguments": { "id": "<id>", "hard": true } }  // physical: GDPR / cleanup only

Default to soft delete — it stops surfacing in search and propagates the rejection to peer stores over sync. Use hard: true only for right-to-forget or operator cleanup.

Correction vs deletion

If the fact changed (not "was wrong to store"), don't delete — record a correction so provenance survives: memory_observe the new statement, then memory_supersede the stale id byId the new one. The engine also supersedes automatically when you observe a contradiction, so plain memory_observe is often enough.

Undo a just-added memory

If the user says "undo that" right after a save, search for the most recent item in scope (memory_list), confirm it's the one, and memory_delete it.

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.
