Sealevel CLI

Command-line interface for Sealevel — the Solana-specialized coding AI.

Interactive terminal session with agent mode, slash commands, and Solana/Anchor developer tools.

Install

pip install sealevel

Requires Python 3.10+.

Quick Start

slm login              # Authenticate via browser (OAuth device flow)
slm                    # Start interactive session

Or set your key manually:

slm config --api-key slm_xxxxxxxxxxxx

Interactive Session

❯ How do I derive a PDA in Anchor?
◆ SEALEVEL
[streaming response with markdown rendering]

❯ /review @src/lib.rs
◆ REVIEWING  src/lib.rs
[security + deprecated pattern analysis]

❯ /explain-error 0x1771
[error decode + fix suggestion]

❯ /gen escrow with atomic token swap -o src/lib.rs
✓ WROTE  src/lib.rs

Agent Mode

Toggle with /agent — the LLM can read, edit, and create files, and run commands:

❯ /agent
✓ Agent mode ON

❯ read src/lib.rs and add an authority check to increment
╭─ read_file ──────────────╮
│  path: src/lib.rs        │
│  ✓ 38 lines              │
╰──────────────────────────╯
╭─ edit_file ──────────────╮
│  path: src/lib.rs        │
│  -2 / +5 lines           │
╰──────────────────────────╯
▸ Allow edit? [y/N/a] y
✓ EDITED  src/lib.rs

Done. Added authority check.

Tools: read_file, write_file, edit_file, run_command, glob_files, grep_files. Read-only tools auto-approve. Write/execute asks permission. Type a to approve all.

• AI-powered /compact — summarizes old conversation to free context
• Auto-upgrade — notifies when newer version is available
• File checkpoints — /undo restores files modified by agent
• Persistent history — input history persists across sessions (Ctrl+R to search)
• Progressive streaming — live markdown rendering with Rich
