fb-post-writer: Security & Code Review for AI Agents | OpenAgentSkill

Overview

Draft a short punchy Facebook Page post, or a longer story post, using a 2026 Facebook hook formula (one-line opinion, tiny number, ask-the-page question, this-or-that, useful tip, story post) picked by goal (shares, comments, reactions). Favors the under-80-character engagement sweet spot, runs the humanizer pass, and publishes via Publora on approval. Use to write a Page post from notes. Not for replying to comments (use fb-engagement-drafter) or auditing a draft (use fb-humanizer).

Facebook Page Post Writer

Ship a short punchy Page post, or a longer story post when the material earns it, using hook shapes that actually travel on a Facebook Page in 2026. The single highest-engagement move on a Page is the short post: posts under 80 characters get a reported ~66% engagement lift, so this skill leads short and only goes long on purpose.

When to use

User says "write me a Facebook Page post about X"
User has a topic or a rough line and wants a sharper, shorter hook
User wants to pick a proven Page-post shape and fill in their voice
User wants a quick draft that auto-publishes on approval

Formulas this skill uses

Code	Formula	Primary goal	Best for
FB1	One-Line Opinion	shares	a sharp, defensible take in one short line
FB2	The Tiny Number	shares	one concrete number that reframes a thing
FB3	Ask-the-Page Question	comments	an easy, fun question the audience answers
FB4	This-or-That	comments	a friendly binary choice readers pick a side on
FB5	Relatable One-Liner	reactions	a specific shared moment, no setup
FB6	Behind-the-Scenes	reactions	a real human moment inside the business
FB7	Useful Tip	shares	one usable tip the reader passes on
FB8	Story Post with a Turn	shares	a longer true story with a quotable turn
FB9	Announcement with Stakes	shares	a launch or news, led human not corporate
FB10	Community Spotlight	shares	featuring a real customer or team member

Full skeletons in ../../references/hook-formulas.md. FB1-FB7 are short-post shapes (lead here). FB8-FB10 are longer story shapes (use on purpose).

Pick by goal first

Goal	Reach for
Shares	FB1, FB2, FB7, FB8, FB9, FB10

Steps

Voice profile first (all drafts). If ../../references/voice-profile.md has filled: yes, load it and match the user's voice fingerprint, hard rules, and CTA/link style throughout. If it is not filled, mention once that fb-humanizer --mode profile can learn their voice from a few posts, then proceed with the generic voice rules.

Gather inputs. Topic, angle, any rough draft, target audience (B2C / B2B / local / community), and the goal (shares / comments / reactions).
Pick the container. Default to a short post (aim under 80 chars). If it is one opinion, number, question, or moment, it stays short. Only escalate to a story post (FB8-FB10) if the idea is a true narrative, a real launch, or a spotlight that needs room.
Pick the formula. Use the goal table to shortlist, then suggest 2-3 that also fit the topic and let the user choose.
Draft the post. Fill the skeleton in the user's voice. Respect the 2026 Facebook rules:
- Lead short. Try to land the whole point under 80 chars.
- First line carries the post (Facebook folds longer posts behind "See more").
- One idea per post. Line breaks as beats.
- 0-2 hashtags, 0-2 emoji, none on a serious take.
- If the post includes a link, write framing text above it (Facebook builds a preview card) and warn that link posts reach fewer people organically.
Humanizer pass. Scrub 2026 AI vocab by paragraph density, cap em dashes (about one per 100 words, never swap one for a period), strip "We are thrilled to announce" and every corporate opener, break stacked triads and reveal bridges. Fix only a story paragraph that reads machine-flat; never manufacture variance, and never fragment a short post for punch. Add an odd-precision number with a named referent or a named entity where the claim allows it. Canonical rules: fb-humanizer V3.
Optional audit. Invoke fb-humanizer --mode audit for a pass-fail check.
Approval card. Show: formula used, full draft, char count (flag if it crosses the 80-char sweet spot), suggested posting window, primary goal.
On approval. Call lib.publish(kind="post", draft_text=<approved>, target_url="https://www.facebook.com/YourPage", platforms=[<FACEBOOK_PLATFORM_ID>], scheduled_time=<iso_or_None>). For a deliberate long story post, pass kind="story". The wrapper handles Publora / manual / diy routing.

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

Lead short. Default to under 80 chars; that is the engagement sweet spot. A long post is a deliberate choice for a story, not the fallback.
The first line must carry the post on its own (everything above the "See more" fold).
One specific number where the claim allows it. "4 minutes" beats "fast".
Never open with "We are thrilled / excited / delighted to announce".
Do not beg for engagement. Earn the share or comment with the post itself.

Anti-patterns (skill will refuse)

"We are thrilled to announce.." and every variant.
Engagement bait ("LIKE and SHARE if you agree", "comment YES", "tag 3 friends").
Em dashes above the cap (more than about one per 100 words), or an em dash swapped for a period.
"Here's what" or "Stop X, start Y" as the opener; "The result?" as a reveal.
Announced candor ("We'll be honest with you", "real talk") with no dated fact behind it.
Staccato stacks ("No X. No Y. Just Z.") and one-word lines added for drama.
Padding a one-line idea into five paragraphs.
Rule-of-three lists without specifics.
"leverage", "fundamentally", "game-changer", "deep dive".
A bare external link with no framing text.
5+ hashtags stuffed at the bottom.
