"""Cursor IDE integration.

Cursor Agent uses the ``.cursor/skills/speckit-<name>/SKILL.md`` layout.
Commands are deprecated; ``--skills`` defaults to ``True``.

The IDE/skills flow is the primary path and works without the
``cursor-agent`` CLI being installed (``requires_cli=False``).  Workflow
dispatch via ``cursor-agent -p --trust --approve-mcps --force <prompt>``
is offered as an opt-in capability — the presence of ``build_exec_args()``
is what indicates dispatch support, mirroring ``CopilotIntegration``.

        Always returns argv (no ``requires_cli`` guard) so workflow
        dispatch is supported even though the integration's ``config``
        sets ``requires_cli=False`` to keep the IDE-only flow unblocked.
        This mirrors ``CopilotIntegration``: dispatch support is signalled
        by overriding ``build_exec_args()``, not by the ``requires_cli``
        flag (which is reserved for the ``specify init`` precheck).

        Mandatory headless flags:

        * ``-p`` — print/headless mode (access to all tools)
        * ``--trust`` — bypass Workspace Trust prompt (CLI exits non-zero
          otherwise)
        * ``--approve-mcps`` — auto-approve MCP server loading (otherwise
          MCP servers stay ``not loaded (needs approval)`` and tool calls
          to them are silently dropped)
        * ``--force`` — auto-approve tool invocations (shell/write/MCP),
          matching the implicit "trusted environment" semantics that other
          integrations (``claude -p``, ``codex --exec``) get by default

        Together these are the minimum set required to make
        ``specify workflow run speckit --input integration=cursor-agent``
        behave the same way as it does for ``claude`` / ``codex``.
        Verified locally: with ``--approve-mcps --force`` the agent can
        call any configured MCP server (e.g. ``dingtalk-doc``) and write
        files during ``/speckit-*`` skill execution; without them the run
        either drops tool calls or exits non-zero on the first approval
        prompt.
