squish

squish is a skill for Claude Code, Codex from michielhdoteth/squish-memory. It costs 157 tokens per session (1,799 once invoked), scanned A, original, MIT.

A memory system that stores useful information from AI-agent sessions and retrieves it in later sessions.

In plain words
What is it for?
It is for sharing project memory across agents, searching stored context, keeping important information over time, and connecting through an MCP server.
Why use it?
It reduces the need to repeat project details, decisions, and context whenever a new agent session or tool starts.

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

squish 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.

Squish: Memory Runtime for AI Agents

Connect once. Remember everywhere. Squish gives ChatGPT, Claude Code, and every AI agent one shared memory through OAuth. Stop re-explaining your project, context, and decisions to every tool.

How Squish Works

Squish is a memory runtime that:

  1. Captures durable signal from agent sessions automatically
  2. Stores memories with embeddings, beliefs, and relationships
  3. Retrieves relevant context across sessions using hybrid search
  4. Decays unimportant memories over time using Ebbinghaus curves
  5. Syncs via OAuth cloud when teams need shared memory

Installation

Option A: Cloud (Recommended - connect to ChatGPT/Claude in 2 minutes)

npx squish-memory
squish cloud login

Then configure your agent to use the Squish MCP server.

Option B: Local (fastest, no cloud dependency)

npm install -g squish-memory && squish install --all

MCP Configuration

For OpenCode

Add to your opencode.json:

"squish": {
  "type": "local",
  "command": ["squish-mcp"],
  "enabled": true
}

For Claude Desktop

{
  "mcpServers": {
    "squish": {
      "command": "npx",
      "args": ["-y", "squish-memory"]
    }
  }
}

For ChatGPT (Cloud)

  1. Go to ChatGPT Settings > Custom MCP Servers
  2. Server URL: https://api.squishplugin.dev/mcp
  3. Auth: Bearer Token (get your key from squishplugin.dev)

Tool Reference

When Squish is connected, these 15 tools are available:

Tool Params What it does
squish_remember content, type?, tags? Save content, decisions, preferences, or facts. Auto-detects routing (memory vs learning vs belief).
squish_recall query, limit?, project? Search memories, learnings, beliefs, and graph entities. Hybrid search. Returns a recall assessment (verdict: confident / qualified / no_reliable_memory).
squish_forget memoryId?, search? Delete a single memory by ID (auto-confirm) or bulk by search query (dry-run with preview).
squish_link action, memoryId?, fromId?, toId? Manage memory associations. action=find traverses the graph. action=add links two memories.
squish_context project?, actorUser? Auto-load relevant context for current project including beliefs, contradictions, and staleness warnings.
squish_stats project? Show memory statistics, signal counts, graph status, places, and system health checks.
squish_inspect memoryId Show why a memory was stored, its classification, beliefs, place, and graph status.
squish_skill action, ... Manage reusable skill documents extracted from memory patterns.
squish_loadout action, ... Bind memory assets to agents; manage visibility rules (ACL).
squish_extract action, hoursBack? Auto-extract reusable skills from accumulated memories via LLM analysis.
squish_feedback targetType, id, signal Reinforce or weaken a recalled item: confirm (correct), used (acted on), or contradict (wrong). Targets: memory, belief, or strategy.
squish_places action, ... Query and manage cognitive places (inbox, wip, ref, board, sparks).
squish_sessions action, ... Search past agent sessions. Sources: opencode, claude-code, codex, gemini, all.
squish_tier action, ... Inspect and manage memory tiers (working / long-term / cold).
squish_dedup action, ... Duplicate detection and merge proposals with review + reverse support.

squish is a skill published in the GitHub repository michielhdoteth/squish-memory (11 stars, last pushed 6d ago), licensed MIT. It adds 157 tokens to every session and 1,799 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
