recording

Captures screenshots on registered computers and manages saved captures. Supports screen recording on macOS and timed screenshot sequences on HarmonyOS, checking available capabilities first and returning the finalized file path when recording stops.

OriginalShow the original description

Capture screenshots on registered computers, record on macOS or HarmonyOS, and manage saved captures. Probe capabilities before recording.

Review the instructions the agent will receive before you install.

Recording and screenshots

  1. Pick the computer (computer_list, or pass computer — it switches).
  2. Check request_access when readiness is unknown. On a supported target, use recording_start with optional display, region, fps and durationSec (macOS auto-stop), or intervalMs (HarmonyOS snapshot cadence).
  3. Do the work (or let the user do it).
  4. recording_stop with the returned id → finalized file path + bytes.
  5. recording_list shows everything saved; recording_status checks one.

Platform truths:

  • macOS: ScreenCaptureKit inside the signed helper captures a display or region straight to .mov — no system recorder selection UI and no desktop dimming overlay. If capture is denied, Screen Recording permission is missing for whoever ran it: the Codewhale Computer Use app when request_access says via: "app", else the terminal that hosts the server — tell the user which, do not retry.
  • Windows and Linux: recording is unavailable pending session-owned recorder cleanup. Use screenshots; installing ffmpeg does not enable it.
  • HarmonyOS: no native CLI recorder; the backend captures snapshot_display frames at intervalMs and muxes with ffmpeg on stop. The receipt labels the mode snapshot-series — never call it real-time.

Screenshots: screenshot returns a saved path, geometry and raster_id. Carry that ID in pixel targets and as the parent of zoom when a target is too small to read. Each zoom returns a new child ID; use it for child-image coordinates. OCR coordinate targets already include their pin. Pins remain reusable while current; older unpinned calls retain latest-raster behavior. A replaced capture, app launch or route change retires the context. On raster_stale or no_raster, observe again; never drop the ID to retry. Pins detect capture replacement, not a changed UI: re-observe after UI changes and verify input separately. An omitted image cannot supply coordinates.

Check Codewhale release readiness through ordered tests, builds, version checks, and manual terminal checks. Record command results and observed behavior, including responsiveness, route isolation, and follow-up input handling, while explicitly identifying any skipped checks.

  • Run automated checks on the actual release branch
  • Check whether a PR merges into the release branch
  • Manually test terminal responsiveness and input behavior
