// Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Configures Letta agent compaction settings and custom summarization prompts. Use when a user asks to change an agent's compaction prompt, improve summaries after context eviction, tune sliding-window or all-message compaction, or design companion/coding-agent continuity summaries.
Navigates archived ChatGPT or Claude-style conversation exports and a MemFS reference archive on demand. Use when recalling what a past assistant knew, searching old conversations, rendering specific chats, seeding reference memory from export sidecars, or mining historical context without doing a full import.
Migrates deprecated Letta Filesystem folders/files to MemFS using markdown document corpora, chunking, local lexical search, and QMD semantic search via the memfs-search skill. Use when replacing folders.files.upload, working with PDFs or document QA, or emulating open_file, grep_file, and search_file behavior.
Semantic search over agent memory files. Use when you need to find conceptually related memory blocks, discover forgotten reference files, check what you already know before creating new memory, or search beyond exact keyword matching. Currently supports QMD (local, no API keys).
Builds and debugs Letta Code channels, including first-party channel adapters and dynamic user channel plugins under ~/.letta/channels. Use when adding Telegram, WhatsApp, Bluesky, Slack, Discord, or custom channel support; testing channel routing, pairing, MessageChannel, runtime dependencies, or channel plugin manifests.
Comprehensive guide for developing Letta agents, including architecture selection, memory design, model selection, and tool configuration. Use when building or troubleshooting Letta agents.

Follow the official CLI get-started steps. Don't guess install commands.
op commands (the shell tool uses fresh TTYs per command, causing re-auth issues without tmux)
brew install tmuxsudo apt install tmuxsudo dnf install tmuxreferences/get-started.md (install + app integration + sign-in flow)references/cli-examples.md (real op examples)op --version.op commands (no direct op calls outside tmux).op signin (expect app prompt).op whoami (must succeed before any secret read).--account or OP_ACCOUNT.The shell tool uses a fresh TTY per command. To avoid re-prompts and failures, always run op inside a dedicated tmux session with a fresh socket and session name.
Socket conventions:
${LETTA_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/letta-tmux-sockets} so they're isolated and easy to clean up.op-auth-$(date +%Y%m%d-%H%M%S)) so you never reuse an old session — previous auth state may be stale or broken.tmux -S "$SOCKET" kill-session -t "$SESSION") to avoid leaking long-running tmux processes.Full example:
SOCKET_DIR="${LETTA_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/letta-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/letta-op.sock"
SESSION="op-auth-$(date +%Y%m%d-%H%M%S)"
tmux -S "$SOCKET" new -d -s "$SESSION" -n shell
