Facebook Research

Follow shared public skill rules in:

• postplus-shared public skill rules

Use this skill when the request is about Facebook account or content research.

This skill is for:

• sampling public follower or following surfaces from a Facebook page or profile
• collecting public page or profile follow-graph items when Facebook exposes them
• collecting one or more public Facebook page, group, or direct post URLs
• discovering a small Facebook post set from a broad query
• normalizing Facebook post metrics into local artifacts
• writing local raw payloads, normalized datasets, and short markdown summaries

This skill is not for:

• LinkedIn collection
• YouTube collection
• TikTok, Instagram, or X workflows
• publishing, deleting, or scheduling posts
• guaranteeing a complete private follower list when Facebook does not expose it publicly

Before Collection Boundary

Before running collection, tell the user that Facebook results are public samples from exposed surfaces, not a complete follower export. If the user's goal requires private or exhaustive audience data, stop and ask for a different source of truth before collecting.

PostPlus Cloud Boundary

This skill depends on host-managed collection capability for the corresponding collection paths.

In the PostPlus runtime:

• do not probe or print provider secrets
• do not ask the user to export them inside chat
• if a collection path returns a stable capability/network hard error, stop immediately instead of trying alternate shell commands

Default Collection Path

Use the hosted follower collection path by default:

• default collection mode: public follower or following items from a page or profile URL
  • use for public follower or following item collection from a page or profile URL
  • tested input shape:
    • startUrls = [{ "url": "https://www.facebook.com/<page-or-profile>" }]
    • resultsLimit
    • followType = "follower" or followType = "following"
  • current observed output fields include:
    • facebookUrl
    • followType
    • title
    • url
    • subtitle_text
    • image
  • this is the default hosted path for Facebook audience-surface research on the public skill surface

Supported Facebook Targets

• public page/profile URL -> follower or following items through hosted collection
• public page/profile URL -> recent posts through hosted content collection
• public group URL -> recent posts
• direct public post URL -> one post

Failure Posture

• fail if the request includes non-Facebook platforms
• fail if no Facebook public URLs can be discovered
• fail if hosted content collection returns malformed items without stable URL or id fields
• fail if hosted follower collection returns no publicly visible follower or following items
• keep raw responses for debugging

Recommended Workflow

1. If the user wants account audience research, start with follower collection using the PostPlus Cloud collection service.
2. If the user wants content research, use the hosted content collection scripts below.
3. If the user wants both, collect follower or following items first, then collect post evidence from the same page or profile.

Do not treat Facebook follower-surface results as a guaranteed full audience export.

Public Skill Execution Contract

• keep collection briefs, raw datasets, normalized outputs, and summary caches under <work-folder>/.postplus/facebook-research/
• keep only final user-facing summaries or shortlist exports outside .postplus/
• compile a small page, post, or discovery brief before the expensive collection step
• start with a bounded first pass:
  • one page or profile
  • one public post plan
  • one summary pass

Hosted Collection Note
