Purpose

Application code for the CLI, including argument parsing, command dispatch, typed errors, browser control, and output rendering.

Mental model & key files

• src/bin/lsearch.rs parses Clap arguments and turns typed errors into stable stderr JSON.
• lib.rs exposes the async run entry point.
• cli.rs is declarative command/argument structure.
• commands/mod.rs is orchestration: attach browser, execute command, print result.
• error.rs keeps operator-facing messages and machine-readable error codes in one place.

Patterns to follow / invariants

• Keep command handlers thin enough to read from top to bottom.
• Prefer typed Error variants over ad hoc strings.
• Any command that may expose browser credentials should redact by default or require an explicit opt-in flag.
• Do not put CDP JSON protocol plumbing in command handlers when it belongs in src/browser/.

Common tasks → first action

• New command: add Clap args, add command branch, update README, add CLI test.
• Managed browser cleanup: keep cleanup dry-run by default, kill exact managed listener PIDs only, and never delete profile cookies/data.
• New output mode: update output.rs only if the envelope contract changes.
• New error: add variant in error.rs and stable code() mapping.

Gotchas

• run owns the parsed Cli; avoid async closures borrowing &mut CdpClient across helper boundaries unless lifetimes are explicit.
• read --format text|markdown and html without a path intentionally write raw body content instead of JSON.
