Post one or more existing image files to Slack as a review. Posts a root anchor message (a Block Kit task card when title/status/checks/links are given) and threads the image(s) beneath it. Returns a JSON status including review_id (poll it with wait_for_review) and the Slack permalink(s). This is the primary tool: pair it with a repro/test that renders the result to a PNG.

Screenshot the running app window (X11/KDE) and post it to Slack as a review. Use only when no offscreen render exists; otherwise prefer send_to_slack with a repro-rendered PNG.

Capture a screenshot WITHOUT posting, and return it for inspection. Compose with send_to_slack: look at the image, then post the returned path if it's the right frame. No Slack call, so no token/scopes are needed.

Block until the human reacts (👍/👎/👀/✏️) or replies in the review thread, or until timeout. Returns a JSON verdict: status is approved / rejected / changes / seen, or 'still_awaiting' on timeout (with a hint to call again). Pair with send_to_slack's review_id.

Non-blocking: read the current review verdict once and return immediately (status approved / rejected / changes / seen / still_awaiting). Use in your own polling loop; use wait_for_review to block until the human responds.

Ask the reviewer a follow-up question IN SLACK and wait for their typed answer. Posts the question into the review thread and pings the channel so an away reviewer (watching Slack, not your terminal) actually sees it — ALWAYS use this instead of asking in the console. Returns the answer (status 'answered'), or 'still_awaiting' + ask_id on timeout; then keep waiting with wait_for_reply(review_id, since_ts=ask_id).

Block until the reviewer posts a thread reply AFTER since_ts, or until timeout. Returns the reply text (status 'answered') or 'still_awaiting'. Use to keep waiting after ask_review timed out.
