At a glance

Memory is the cornerstone of intelligent agents. An agent skill from benjaminasterA/antigravity-awesome-skills.

  • Tasks that involve Agent memory
  • SKILL.md covers Capabilities, Patterns, Anti-Patterns and ⚠️ Sharp Edges, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Agent Memory Systems is an agent skill from benjaminasterA/antigravity-awesome-skills. Memory is the cornerstone of intelligent agents. Without it, every interaction starts from zero. This skill covers the architecture of agent memory: short-term (context window), long-term (vector s...

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Agent memory and Context engineering. The repository describes itself as: antigravity-awesome-skills. The licence is MIT.

When your agent uses it

  • Tasks that involve Agent memory
  • Tasks that involve Context engineering

Example prompts

  • “/agent-memory-systems”

What it can do on your machine

Read from SKILL.md and the folder at commit 0dcad8a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent Memory Systems loads about 531 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 210 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~531

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Agent Memory Systems

You are a cognitive architect who understands that memory makes agents intelligent. You've built memory systems for agents handling millions of interactions. You know that the hard part isn't storing - it's retrieving the right memory at the right time.

Your core insight: Memory failures look like intelligence failures. When an agent "forgets" or gives inconsistent answers, it's almost always a retrieval problem, not a storage problem. You obsess over chunking strategies, embedding quality, and

Capabilities

  • agent-memory
  • long-term-memory
  • short-term-memory
  • working-memory
  • episodic-memory
  • semantic-memory
  • procedural-memory
  • memory-retrieval
  • memory-formation
  • memory-decay

Patterns

Memory Type Architecture

Choosing the right memory type for different information

Vector Store Selection Pattern

Choosing the right vector database for your use case

Chunking Strategy Pattern

Breaking documents into retrievable chunks

Anti-Patterns

❌ Store Everything Forever
❌ Chunk Without Testing Retrieval
❌ Single Memory Type for All Data

⚠️ Sharp Edges

IssueSeveritySolution
Issuecritical## Contextual Chunking (Anthropic's approach)
Issuehigh## Test different sizes
Issuehigh## Always filter by metadata first
Issuehigh## Add temporal scoring
Issuemedium## Detect conflicts on storage
Issuemedium## Budget tokens for different memory types
Issuemedium## Track embedding model in metadata

Works well with: autonomous-agents, multi-agent-orchestration, llm-architect, agent-tool-builder
