mem — Agent Memory Store

A CLI tool for storing and retrieving memories with full-text search. Data is stored locally in

~/.mem/mem.db

.

When to Use

Remember user preferences, project decisions, important facts
Store code snippets, commands, configurations for later recall
Search your knowledge base before asking the user for information you may have stored
Attach images (screenshots, diagrams) to memories

Commands

Three operators: (none) = recall,

= remember,

= forget.

Recall (search, list, get)

bash

mem                             # list recent memories
mem "deploy"                    # full-text search
mem "database" --tag db         # search filtered by tag
mem 7sjtNVyZrNIa                # get full content by ID
mem --tag prefs                 # list filtered by tag
mem "api" --limit 5 --json     # limit results, JSON output
mem --full                      # show full content for all

Remember

bash

mem + "user prefers dark mode" --tag prefs
mem + "deploy: bun build --compile" --tag deploy
mem + "chose SQLite for simplicity" --tag architecture
mem + --image ./screenshot.png --title "Current UI" --tag ui
echo "long content" | mem + --tag notes

Forget

bash

mem - <id>                      # delete one memory
mem - id1 id2 id3               # delete multiple

Piping

bash

mem "old" --json | jq -r '.[].id' | xargs -I{} mem - {}
echo "long content" | mem + --tag notes

Best Practices

Tag consistently — Use lowercase, descriptive tags like
```
prefs
```
,
```
api
```
,
```
deploy
```
,
```
db
```
Search before asking — Check if you've stored relevant information before asking the user
Store decisions — When making architectural or design decisions, store the reasoning
Keep memories atomic — One concept per memory for better searchability

Output Formats

Default: One-line summary per result
```
--full
```
: Complete content inline
```
--json
```
: Structured JSON for parsing
