Market Social — Multi-Platform Content

Generate social content that respects each platform's native format. A LinkedIn post is not a long tweet. An Instagram caption is not a blog intro. A TikTok script is not a headline.

Platform Specs (character limits and native formats)

| Platform | Limit | Native format | |---|---|---| | X (Twitter) | 280 chars (free) / 25,000 (Premium) | Punchy single posts or threads. First tweet hooks. Threads use "🧵" or numbered. | | LinkedIn | 3,000 chars post body | Story-led, line-break-heavy, no links above the cut (algorithmic penalty). | | Instagram | 2,200 caption / 30 hashtags max | Hook in first line (before "more"), 5–15 hashtags in first comment, emoji for scanability. | | TikTok | 2,200 caption / video is the content | Caption is a hook. Script should be 15–60s with hook in first 3s. | | YouTube Shorts | Video + 100-char title | Hook first 2 seconds, pattern interrupt at 5s. | | Threads | 500 chars | Conversational, less polished than LinkedIn. | | Facebook | 63,206 chars (use ~80 for best reach) | Short + link, or native video. | | Pinterest | 500 char description / vertical image | Keywords + title are the ranking signal. |

Content Pillars (pick 3–5 per brand)

| Pillar | Purpose | Example formats | |---|---|---| | Educational | Teach, build trust | How-tos, frameworks, breakdowns | | Behind the scenes | Humanize | Day-in-life, process, team | | Social proof | Credibility | Case studies, testimonials, stats | | Contrarian / POV | Attention + distinction | Hot takes, pattern breaks | | Tactical | Immediate value | Tips, hacks, templates | | Story | Emotional connection | Origin, founder, customer stories | | Entertainment | Reach | Memes, humor (if on-brand) | | Product | Direct promo | Launches, updates, demos |

The 80/20 rule: 80% value-driven (education, story, proof), 20% direct promo.

Platform-specific post structures

X — Single

Hook (line 1)
Evidence / story / punch
CTA (optional)

X — Thread

1/ Hook — specific, contrarian, or curiosity
2/–N/ Beats: context → story → lesson → example → takeaway
Last/ Wrap + soft CTA ("If this helped, RT the top.")

LinkedIn

Line 1: Hook (must survive the "see more" cut)
Line 2: Blank
Line 3–4: Setup
[line breaks]
Story / insight / framework in short lines
[line breaks]
Takeaway
[line breaks]
CTA — question or invitation
(No external links in body. Drop links in first comment.)

Instagram caption

Hook (before "more")
Blank line
Story or breakdown with emoji bullets
Takeaway
CTA (save, share, comment)
.
.
.
#5–15 hashtags

TikTok / Shorts script

[0–3s] HOOK — visual + spoken pattern interrupt
[3–8s] SETUP — what this is about
[8–25s] PAYOFF — the actual thing
[25–55s] PROOF or REPEAT
[last 2s] CTA — "follow for more", "link in bio"

Pre-flight

1. Load BRAND-VOICE.md if present.
2. Ask: topic, target platforms, frequency, goal (awareness / engagement / leads / sales).
3. Confirm content pillars if not already documented.

Output Format

When the user asks for a post pack:

## Social Post Pack — [Topic]

**Brand voice:** [summary from BRAND-VOICE.md or inferred]
**Pillar:** [which one]
**Goal:** [awareness / engagement / etc]

---

### X (Single)
[Draft — must fit 280 chars; include char count]

### X (Thread)
1/ [hook]
2/ [beat]
...

### LinkedIn
[Full post with line breaks preserved]

### Instagram
**Caption:**
[Hook + body]

**Hashtags (first comment):**
#tag1 #tag2 ...

### TikTok / Shorts script
**Hook (0–3s):** [visual + line]
**Setup (3–8s):** ...
**Payoff (8–25s):** ...
**CTA (last 2s):** ...

### Threads
[Draft — under 500 chars]

When generating a content calendar

Use python3 scripts/social_calendar.py --pillars "" --days 30 to generate a pillar-aware skeleton, then fill in specific topics. Output as a table:

| Day | Pillar | Platform(s) | Topic | Status | |---|---|---|---|---|

Quality Bar

• Respect the character limits. A 320-char "tweet" wastes the client's time.
• Lead with the hook on every platform. If the first line is boring, the rest is invisible.
• Don't copy-paste the same post across platforms. Rewrite for each.
• Never invent hashtags that don't exist or that have been hijacked.
• If the client has no strong POV, say so — social without a POV dies slowly.
