recall

recall is a skill for Claude Code from mem9-ai/mem9. It costs 12 tokens per session (556 once invoked), scanned A, original, Apache-2.0.

A skill for searching Mem9, a memory service that stores information from earlier work, for context relevant to the current request.

In plain words
What is it for?
Use it when historical context from Mem9 could help answer or complete the current task; it requires Mem9 setup and access credentials.
Why use it?
It helps recover useful past decisions or information instead of treating every request as if it were new.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the claude-plugin plugin — 3 skills, 5 hooks shipped together

About the project

mem9 is a persistent memory service for AI agents that preserves information across sessions and machines and can share it among multiple agents. It is used with OpenClaw, coding agents, workflow platforms, and custom clients that need shared storage and recall. The catalogue add-ons connect agents and workflows to mem9 memory.

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

recall scanned grade A with 1 finding 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 7d 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.

What it actually says

Mem9 Recall

Use this skill when the current request could benefit from historical context stored in Mem9.

Steps

  1. Check ${CLAUDE_PLUGIN_DATA}/auth.json. If it is missing, tell the user to run /mem9:setup first.
  2. Use ${CLAUDE_PLUGIN_DATA}/auth.json only as request credentials. Do not print the file contents or the API key.
  3. Search Mem9 with the current question across all agents in the account (no agent_id filter).
set -euo pipefail

auth_file="${CLAUDE_PLUGIN_DATA}/auth.json"
test -f "$auth_file"
read_api_key_and_base_url="$(node -e 'const fs=require("node:fs"); const data=JSON.parse(fs.readFileSync(process.argv[1],"utf8")); const values=[data.api_key || "", data.base_url || "https://api.mem9.ai"]; process.stdout.write(values.join("\t"));' "$auth_file")"

Return only the memories that help with the current question. Never reveal secret values.

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.
