[Bug]: opencode integration unusable on opencode v2 — run --command removed (upstream: anomalyco/opencode#49903)

[markuswondrak]

Bug Description

The opencode integration dispatches commands as opencode run --command <name>, but opencode v2 removed --command. Every workflow command step fails immediately with Unrecognized flag: --command (exit 1).

Tracking report — no spec-kit-side workaround is proposed. The integration can only be fixed once upstream decides the v2 headless command path. Upstream: anomalyco/opencode#49903.

Steps to Reproduce

1. Install opencode v2 (opencode --version → 2.0.8).
2. Run a workflow command step with command: speckit.specify, integration: opencode.
3. Spec Kit emits opencode run --command speckit.specify ….

Expected Behavior

The command is dispatched and runs.

Actual Behavior

opencode run --command speckit.specify … → ERROR: Unrecognized flag: --command in command opencode run, exit 1 (failed in ~54 ms in run cockpit-d012782e9339).

Additional Context

• src/specify_cli/integrations/opencode/__init__.py:62-67 appends --command.
• The slash prompt is synthesized internally, so users cannot avoid it.
• Upstream report: run: --command removed in v2 and slash commands are not expanded — no CLI path for headless command invocation anomalyco/opencode#49903. Related: [Bug]: Systematic build_exec_args() audit — CLI dispatch flags unverified for 11+ integrations #2416, [Bug]: opencode integration dispatch fails — uses unsupported -p flag instead of run subcommand #2409, [Bug]: Amp dispatch sends -p/--model/--output-format — none of these exist in the Amp CLI #4580.
• Requested handling: tracking issue (e.g. triage-can-wait) until upstream decides, to prevent duplicate reports.
