A command for working with memo, a persistent memory service for saving and retrieving notes across conversations. It can search, save, inspect, list, update, and maintain those memories when the required tools are available.

Use it to save an insight, list or inspect saved memories, view statistics, or update an existing memory. If memo is not registered, it explains how to register it.

It keeps useful decisions and insights from being lost between sessions and provides a consistent way to manage them.

memo — Command for Claude Code by jagoff

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/jagoff/memo

Made for: Claude Code.

Or install memo, the plugin that ships this one along with the rest of its 4 skills, 1 command, 4 hooks, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00012	$0.00514
Opus 5.5	$0.00005	$0.00206
Sonnet 5.5	$0.00002	$0.00103
Haiku 4.5	$0.00001	$0.00051

Measured 1mo ago against content hash 83799a76514a, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

memo 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.

What it actually says

/memo

Route $ARGUMENTS to the local memo MCP server. Use MCP tools whenever the active profile exposes them; use the isolated memo CLI for maintenance commands that are intentionally absent from the default 13-tool agent profile.

Preflight

If MCP tools named mcp__memo__memo_* are not available, tell the user to register memo first:

memo install-slash --client claude-code
# or only print the MCP command:
memo mcp-command --client claude-code
# other client installers:
memo install-slash --client codex
memo install-slash --client devin-desktop

Then open a new Claude Code session so the / menu and MCP tools reload.

Routing

Empty arguments: smart-capture the actionable insight from the current turn and call mcp__memo__memo_save.
stats: call mcp__memo__memo_stats when available; otherwise run memo stats.
list [n]: call mcp__memo__memo_list when available; otherwise run memo list --limit n.
save <text>: derive a short title, type, and tags, then call mcp__memo__memo_save.
get <id|prefix>: call mcp__memo__memo_get.
update <id|prefix> ...: call mcp__memo__memo_update when available; otherwise run memo edit.
delete <id|prefix>: ask for explicit confirmation, then call mcp__memo__memo_delete when available; otherwise run memo delete --yes.
reindex: call mcp__memo__memo_reindex when available; otherwise run memo reindex.
doctor [--gc] [--fix]: run MEMO_NONINTERACTIVE=1 memo doctor ....
Anything else: semantic search via mcp__memo__memo_search with limit=5 and body_chars=280.

Keep output compact. For search results, show score, type, title, updated date, and id prefix. For saves/updates/deletes, show the resulting id and title.

Changes

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.
