memory-search

memory-search is a command for coding agents from ScottRBK/forgetful. It costs 7 tokens per session (337 once invoked), scanned A, original, MIT.

A command for searching Forgetful, a knowledge store for coding agents, for memories related to a natural-language query. It returns relevant stored items and optionally their links.

In plain words
What is it for?
Use it to look up decisions, conventions, facts, or other remembered project information, optionally narrowed to a particular project.
Why use it?
It saves time when project knowledge is spread across many stored memories and makes it easier to find related information without knowing exact titles.

Getting it into your agent

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

memory-search 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.

What it actually says

Search the Forgetful knowledge base for relevant memories.

Your Task

Perform a semantic search using execute_forgetful_tool("query_memory", {...}) with the user's query.

Query: $ARGUMENTS

Search Parameters

Use these parameters for the search:

{
  "query": "<user's search query>",
  "query_context": "User initiated search via /memory-search command",
  "k": 5,
  "include_links": true,
  "max_links_per_primary": 3
}

If the query mentions a specific project, add project_ids filter.

Response Format

Present results clearly:

  1. Summary: Brief overview of what was found (or "No relevant memories found")
  2. Primary Memories: For each memory show:
    • Title (with importance score)
    • Key content snippet
    • Tags
    • Linked memories if relevant
  3. Suggestions: If results seem incomplete, suggest refining the query or creating a new memory

Example

User: /memory-search authentication patterns

You search and respond:

Found 3 memories about authentication patterns:

1. **FastAPI JWT Authentication** (Importance: 9)
   JWT middleware using httponly cookies for security...
   Tags: security, authentication, fastapi

2. **OAuth2 Decision** (Importance: 8)
   Chose OAuth2 over API keys for user-facing auth...
   Tags: decision, oauth, security

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.
