Meeseeks CLI - UI/Terminal Guidance

Meeseeks CLI - UI/Terminal Guidance

Scope: this file applies to the apps/meeseeks_cli/ package only. It covers the terminal UI (renderer + dialog toolkit) and how CLI output is produced.

Goals (UI)

• Keep the terminal UI simple, fast, and readable.
• Prefer built-in components from the rendering/dialog toolkits over custom rendering.
• Stay DRY/KISS: build reusable UI helpers instead of ad‑hoc formatting.
• Preserve terminal scrollback (no full-screen takeovers).

Rendering Pipeline (How we produce output)

• Entry point: apps/meeseeks_cli/src/meeseeks_cli/cli_master.py (run_cli).
• Rendering is done via a single console renderer instance.
• High-level sections:
  • Startup header panel plus a ready line with session info.
• Action plan checklist (panel + text + group).
• Tool results as cards (panel + columns).
• Response panel (Markdown in a bold border).
• Logging is gated by -v/--verbose and themed darker for CLI runs.
• Tool execution shows a lightweight spinner while a tool is running.

Section styles (keep consistent)

• Action Plan: checklist in a panel titled :clipboard: Action Plan, border cyan.
• Tool Results: per-tool panels, title prefix :wrench:, border magenta.
• Response: :speech_balloon: Response, border bold green.
• Tool result cards dim unless they are the current focus; outputs are collapsed unless verbose and JSON renders formatted.

If you change any of these, update this file.

Dialogs / Prompts (Interactive Toolkit)

We use Rich for the normal CLI rendering (header, plans, tool cards, responses). We use Textual only for full-screen style prompts (dialogs), not for the main output. Do not run Rich rendering and Textual dialogs concurrently: Textual runs a blocking app loop and mixing it with live Rich rendering/spinners can deadlock or break terminal state.

DialogFactory (reusable)

• select_one: single-select list (OptionList)
• select_many: multi-select list (SelectionList)
• prompt_text: text input (Input)
• confirm: yes/no

Key behaviors:

• Runs inline to avoid clearing scrollback.
• Auto-fallback to plain prompt when no TTY or MEESEEKS_DISABLE_TEXTUAL=1.
• Escape/Q cancels; Enter accepts.
• Interactive app runs are blocking; do not use them for long-lived UI in the REPL loop.

Commands currently using dialogs

• /models: single-select model picker (TTY only).
• /tag (no args): Text input for tag name.
• /fork (no args): Text input for optional tag.
• /mcp select: Multi-select to filter MCP tools displayed.

If you add a new interactive flow, use DialogFactory instead of writing custom prompts.

Commands overview (keep in sync)

• /help: show commands.
• /exit or /quit: exit the CLI.
• /new: start a fresh session.
• /session: show current session id.
• /summary: show current session summary.
• /summarize or /compact: summarize + compact transcript.
• /tag NAME: tag the current session (dialog when NAME omitted).
• /fork [TAG]: fork current session (dialog when TAG omitted).
• /plan on|off: toggle action plan display.
• /mcp [select|init]: list MCP tools, filter, or scaffold config.
• /models: model wizard (interactive only).
• /automatic: auto-approve all tool actions in this session.

Core Files (UI-related)

• apps/meeseeks_cli/src/meeseeks_cli/cli_master.py: main loop, output sections, startup panel.
• apps/meeseeks_cli/src/meeseeks_cli/cli_commands.py: commands, model wizard, MCP listing.
• apps/meeseeks_cli/src/meeseeks_cli/cli_dialogs.py: dialog factory.
• apps/meeseeks_cli/src/meeseeks_cli/cli_context.py: state shared across commands.

Environment knobs (UI-relevant)

• OPENAI_API_BASE / OPENAI_BASE_URL: printed in the ready panel.
• DEFAULT_MODEL / ACTION_PLAN_MODEL: used when --model is not set.
• MEESEEKS_DISABLE_TEXTUAL=1: disable dialogs (force fallback).
• MEESEEKS_CLI=1: set at startup to tag CLI runtime context.
• MEESEEKS_LOG_STYLE=dark: default log styling for the CLI.
• MESEEKS_MCP_CONFIG: MCP server config used for discovery.
• MESEEKS_TOOL_MANIFEST: optional override for tool registry.

KISS / DRY rules for UI work

• Reuse existing render helpers and dialogs; add small helpers if needed.
• Avoid bespoke widgets or heavy layouting unless strictly required.
• Prefer toolkit defaults; override only when UX needs it.
• Keep new UI logic near existing UI code (cli_master.py, cli_dialogs.py).

Orchestration + testing guardrails (CLI-facing)

• Show tool activity clearly (plan, spinner, tool panels) before final response.
• Do not print raw tool output as the final answer; let the core synthesize.
• Tests should drive a real CLI flow with fake tools/LLM outputs; avoid over-mocking.
• Keep permission prompts deterministic in tests (auto-approve or stub).
• Treat language models as black-box APIs with non-deterministic output; avoid anthropomorphic language in docs/changes.

Keep this file updated

Whenever you change:

• Section layouts, styles, or titles
• Dialog behaviors or new dialog types
• UI-related env vars or dependencies …update this document to reflect the new behavior.

Doc hygiene:

• Keep this file concise and actionable; link to code instead of duplicating it.
• This is a nested file for the CLI package; it should override root guidance only when CLI-specific.
