Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

generate-social-media-captions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Generate Social Media Captions (Platform-Native Copywriting) (AI Skill)

Overview

Default AI social media copy is instantly recognizable and easily ignored: it is loaded with excessive emoji spam (🚀 🔥 ✨), generic motivational filler ("Thrilled to announce..."), and 25 irrelevant hashtags.

The Platform-Native Copywriting Protocol instructs the model to adhere to the exact typography, character limits, whitespace rhythm, and conversational norms of each specific social network.

Master Platform-Specific Prompt Templates

Pattern 1: The Multi-Platform Announcement Matrix

Use when launching a product, sharing an article, or announcing a milestone:

I want to announce [NEWS / MILESTONE / LESSON LEARNED].
Core Message: [INSERT CORE DETAILS & KEY METRIC].

Generate 2 distinct platform-native versions:

### 1. LinkedIn Post (Story-Driven)
- Opening: Punchy, contrarian 1-line hook.
- Structure: Short 1-2 sentence paragraphs with whitespace.
- Content: The human story, the initial struggle/failure, and the key business takeaway.
- Tone: Candid, professional, humble, zero cheesy corporate buzzwords.
- Banned: No "Thrilled to announce", "humbled", "game-changer", or rocket emojis.

### 2. X / Twitter Post (High-Velocity)
- Length: Under 250 characters.
- Tone: Direct, punchy, like an engineer or founder sharing notes.
- Format: Hook + 2 bullet points + 1 link placeholder. Zero hashtags.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
