Proposed fix: [Factory Droid CLI] --fork rejected: 'cannot be used with --mission' / '--worktree' / '--use-spec or --spec-model' / 'is not supported with --input-format stream-jsonrpc, --output-format
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Drop --fork (start fresh) for mission/spec/worktree runs; for ACP/JSON-RPC integrations fork via the protocol client rather than the flag; pass a session id or --last with resume --fork.
Option: Drop --fork (start fresh) for mission/spec/worktree runs; for ACP/JSON-RPC integrations fork via the protocol client rather than the flag; pass a session id or --last with resume --fork. [evidence: official_recommended_action]
Applies when: Forking a session with `droid exec --fork` (or resume --fork) combined with mission, worktree, spec or protocol modes
Steps:
1. Decide whether you need a fork or a fresh mission/spec session and remove the conflicting flag.
2. For `resume --fork`, add <session-id> or --last.
Expected: The error no longer appears.
