Claude Code's CLI parser greedily consumes positional tokens following variadic flags (--tools, --add-dir) as flag arguments. Moving the initial_prompt positional arg before the variadic flag loops in both the Claude and Codex backends prevents the greeting from being consumed as a tool/directory name instead of the auto-submit prompt. Adds VARIADIC_CLAUDE_FLAGS registry, parametrized arch ordering test, and per-flag ordering contract tests to prevent silent regressions. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…er assertion Reviewer (finding tests/execution/backends/test_codex_backend.py:712): commit 28ef57b weakened 'assert spec.cmd[-1] == "hello"' to 'assert "hello" in spec.cmd' and renamed the test. With no variadic flags, CodexBackend places initial_prompt as the last element unconditionally; the weaker assertion no longer catches positional regressions.

Reviewer (findings test_commands.py:70 and :78): commit 28ef57b injected identical ordering assertions into test_includes_initial_prompt_as_positional_arg AND added a dedicated test_initial_prompt_precedes_tools_flag covering the same inputs and assertions. Fix: revert test_includes_initial_prompt_as_positional_arg to its original intent (presence + non-headless check only, no tools= arg) and remove the redundant dedicated test. Ordering coverage is retained by test_initial_prompt_precedes_all_variadic_flags_combined and the arch test. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
ClaudeCodeBackend.build_interactive_cmd()appends theinitial_promptpositional argument after variadic CLI flags (--tools,--add-dir). Claude Code's CLI parser treats these flags as variadic (<tools...>,<directories...>), so the parser greedily consumes the greeting string as a tool/directory name rather than as the auto-submit initial prompt. The session launches but sits idle at an empty>prompt. The fix movesinitial_promptbefore variadic flags, addsVARIADIC_CLAUDE_FLAGSmetadata to the flags registry, and adds ordering contract tests. The same fix is applied to the Codex backend.Requirements
