fix: remove auto v1 migration prompt #265
Conversation
WalkthroughRemoved interactive v1 migration from the CLI, hardened cross-platform single-key input in the v1 migrator, expanded run command help and execution-mode options, deleted the AI-agent CLI design doc, and updated a test to call CLI help directly. Changes

participant User
participant CLI as mcpm CLI
participant Help as Help Renderer
participant Migrator as v1_migrator
User->>CLI: run `mcpm` or `mcpm --help`
activate CLI
Note over CLI: v1 migration detection/prompt removed
CLI->>Help: print header
CLI->>Help: print help text (global footer suppressed)
Help-->>CLI: composed help output
CLI-->>User: display help
deactivate CLI
Note right of Migrator: `_wait_for_keypress` now:\n- tries Unix `termios`/`tty` raw read\n- tries Windows `msvcrt.getch()`\n- falls back to `input()` for non-tty/errors

43-50: Stabilize help assertions (case-insensitive) to reduce brittleness.Lowercase once and assert against that to avoid future styling/casing flakes.
- assert result.exit_code == 0 - assert "global configuration" in result.output.lower() - assert "profile" in result.output.lower() - assert "install" in result.output - assert "run" in result.output + assert result.exit_code == 0 + out = result.output.lower() + assert "global configuration" in out + assert "profile" in out + assert "install" in out + assert "run" in outAdditionally, consider adding a separate test invoking
mainwith no args ([]) to assert header shows once and the global footer isn’t duplicated. I can draft it if helpful.src/mcpm/migration/v1_migrator.py (2)
46-67: Don’t block in non‑interactive contexts; flush prompt first.Without a TTY (CI, piped input), this can hang waiting for input. Flush the prompt and short‑circuit when stdin isn’t a TTY.
- console.print(message, end="") + console.print(message, end="") + # Ensure prompt is visible before blocking + try: + console.file.flush() + except Exception: + pass + # In non-interactive contexts (e.g., CI/pipes), don't wait + try: + is_tty = sys.stdin.isatty() + except Exception: + is_tty = False + if not is_tty: + console.print() + return
48-66: Leverage Click’s cross‑platform pause to simplify.You can replace the platform branches with
click.pause()which already handles Windows/Unix, echo, and TTY checks.Example replacement inside this method:
import click # at top of file def _wait_for_keypress(self, message: str): console.print(message, end="") try: console.file.flush() except Exception: pass try: click.pause("") # empty string to avoid duplicate message except (EOFError, KeyboardInterrupt): pass console.print()

66-71: Port auto-discovery ignores --host; can mis-detect availabilityBinding check is hardcoded to 127.0.0.1. If users pass --host 0.0.0.0 (or another IP/IPv6), a port may be reported “free” yet fail on uvicorn bind (or vice versa). Bind against the requested host (and support IPv6) to avoid false positives/negatives.

167-169: Run option group updated with --sse/--host — alignment looks goodThe option group now mirrors the run command’s flags.
Optional: rename the group to “Execution & Network” (or “Serving Options”) since it now includes network params, not just “mode”.

73-82: Friendlier URL when binding to all interfacesWhen host is 0.0.0.0 or ::, the printed URL isn’t directly reachable. Show localhost in the hint to reduce confusion.

145-177: Reworked usage doc is clear and actionableExamples and tips read well; defaults and exclusivity are obvious.
134-143: New flags (--sse, --host) and clearer help — LGTMOptions --http, --sse, --port, --host and -h are present in src/mcpm/commands/run.py and the mutual-exclusivity/help text is explicit.
