memory

memory is a skill for Claude Code, Codex from aitytech/agentkits-memory. It costs 35 tokens per session (547 once invoked), scanned A, a copy of memory-workflow, MIT.

A memory-search skill for AI coding assistants. It uses a three-layer process: a quick index, the surrounding timeline, and the complete stored record.

In plain words
What is it for?
It is used to recall past work, architectural decisions, project conventions, earlier errors, and their solutions.
Why use it?
It helps find reliable project history when the current conversation does not contain the needed context.

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 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.

AgentKits Memory Skill

When to Activate

Use this skill when:

  • User asks about past work, previous sessions, or what was done before
  • User references a decision, pattern, or error you don't have context for
  • You need project history, conventions, or architectural decisions
  • User asks "what did we do about X?" or "how did we handle Y?"
  • You're missing context that should exist from earlier sessions
  • Starting work on a feature that may have prior decisions recorded

Prerequisites

Before searching, check if memories exist:

memory_status()

If the database is empty, skip recall and inform the user.

3-Layer Search Workflow

Layer 1: Search Index (lightweight, ~50 tokens/result)

memory_search(query="your search term")
  • Returns IDs, titles, categories, dates, and relevance scores
  • Filter by category: decision, pattern, error, context, observation
  • Filter by date: dateStart="2025-01-01", dateEnd="2025-12-31"
  • Sort: orderBy="relevance" (default), "date_asc", "date_desc"

Layer 2: Timeline Context (understand what happened around a result)

memory_timeline(anchor="MEMORY_ID")
  • Shows what happened before/after a specific memory
  • Helps understand the sequence of events
  • Use when you need temporal context

Layer 3: Full Details (only for filtered IDs)

memory_details(ids=["ID1", "ID2"])
  • Returns complete content for selected memories
  • Limit to 3-5 IDs at a time to conserve tokens
  • NEVER fetch details without filtering through Layer 1 first

Quick Topic Recall

For a fast overview of everything known about a topic:

memory_recall(topic="authentication")

This returns a grouped summary. Follow up with memory_details for specifics.

Token Efficiency Rules

  1. ALWAYS start with memory_search (Layer 1), never jump to memory_details
  2. Review search results and select only relevant IDs before fetching details
  3. Use filters (category, date range) to narrow results
  4. Limit memory_details to 3-5 IDs per call
  5. This workflow saves ~87% tokens vs fetching everything at once
