Description

Add harness-support wait-for-events --run-ids <id>... so third-party harnesses can register targeted waits using workload credentials. The command returns the server's waiting_on_run_ids immediately; the agent must then end its turn, not complete its task.

A dedicated wait-for-events skill mirrors the native tool guidance and is linked from child orchestration. Children wait only for expected parent replies and must finish completed assignments. Updated minimum platform-plugin versions ensure cached Claude/Codex installs receive the skill. No desktop Waiting UI or idle-timeout changes are included.

Requires the server API stack ending at https://github.com/warpdotdev/warp-server/pull/21020 and the companion plugin releases before rollout. This supersedes closed #15589.

Companions: Claude skill, Codex skill, server child prompts. Merge the plugin releases before this minimum-version bump; deploy the API and CLI before enabling the new prompt guidance.

• Where appropriate, screenshots or a short video of the implementation are included below (especially for user-visible or UI changes). Non-rendered CLI/API path; no visual proof required.

Testing

• cargo nextest run -p warp_cli -p warp --lib -E 'test(wait_for_events) | test(plugin_manager::claude::tests) | test(plugin_manager::codex::tests)': 70 passed. Covers parser targets, authenticated request/response and rejected registration, plus plugin-manager compatibility.
• cargo clippy -p warp_cli -p warp --all-targets --tests -- -D warnings: passed.
• ./script/format: applied after validation.
• Cross-repository skill-body and marketplace-version consistency checks: passed.
• Live registration/resumption was not exercised against the unmerged server API.
• I have manually tested my changes locally with ./script/run. Not run; verified through parser and real HTTP-client mock tests.
