Comment on a Facebook post, after you approve

Searches Facebook as the signed-in account, picks the first post genuinely about the topic, opens that post's comments sheet and, if asked, turns on "comment as an anonymous member" where the group offers it. Then it stops holding the phone. The user sees which post it chose, and as whom it will comment, before anything is written. On approval it types the comment and posts it, then confirms the comment is in the list rather than trusting the tap.

Inputs

If the user has not written the comment, draft it from the post the first call found and show it to them before the second call, never before the first.

Run it

1. Find the post, open its comments, set the identity. Nothing is written.

run_task({
  "phases": [{
    "launch": "com.facebook.katana",
    "goal": "In the Facebook app, tap the Search button at the top right, type '<topic>', and press enter. Stay on the All tab of the results. Find the first post that is <about> and tap the Comment button in the same card as that post's text, not the post text itself and not a Reply button on someone's comment. A comments sheet opens with a field that reads 'Write a public comment…'. <ANON> Do not type, post, like, share, join or follow.",
    "typeTexts": ["<topic>"],
    "pauseWhen": "the comments sheet of the chosen post is open, with the 'Write a public comment…' field at the bottom",
    "maxSteps": 18
  }]
})

For anonymous replace <ANON> with: Then tap the small profile chip at the left of that field; a sheet opens with your name, 'Create a nickname' and a switch labelled 'Comment on this post as an anonymous member'. Turn that switch on and tap Close to return to the comments sheet. Otherwise remove <ANON>.

Poll get_task_status(task_id, wait_seconds: 30) until the status is paused. The pause carries context.labels, which include the post's text and the comments already there, so you can show the user what it chose.

2. Show the user the post, the identity, and the comment. Wait for a yes.

3. Post it.

resume_task({
  "task_id": "<id>",
  "text": "<comment>",
  "allowWrites": true,
  "repeat": 1,
  "countLabel": "^(Post|Send)$",
  "goal": "Tap the 'Write a public comment…' field, type the comment into it, then tap the blue send arrow at the right of the field to post it. Do not like, share, join or follow.",
  "maxSteps": 8
})

Poll until done. To walk away instead, call resume_task({ task_id, abandon: true }): the sheet is closed, the phone released, and nothing is posted.

What comes back

result.phases[0].sent lists the comment only when its effect was verified on screen: the field emptied and the comment appeared in the list, under your name or as "Anonymous participant". Report that, not the tap. An unanswered pause expires after ten minutes and the phone is released.

Notes

• Anonymous is a group setting. The switch exists only where admins have turned on anonymous participation; elsewhere the identity sheet shows only your name and "Create a nickname". The run then comments as you; the pause is where you notice.
• A duplicate cannot be seen when anonymous. Your earlier anonymous comments look like everyone else's, so the "already commented" check by name does not work. Keep your own record of posts commented on.
• A comment's own Reply button opens a reply to that comment, not to the post; the goal names the post's Comment button for that reason.
• The comments sheet sorts by Most relevant by default; that does not affect posting.
• Facebook removes promotional comments and bans repeat offenders, and group rules often forbid links. Comments that answer the question carry; keep links out unless the group allows them.
