Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.02302 |
| Opus 5 | $0.00026 | $0.01151 |
| Sonnet 5 | $0.00010 | $0.00460 |
| Haiku 4.5 | $0.00005 | $0.00230 |
Grade A, and why
social-post 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 8d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Social Post
Core Principles
For a local shop or restaurant, social media is the most cost-effective marketing channel you have — but only if the content is consistent, authentic, and platform-appropriate. A single great photo of today's special can bring in more customers than a $500 ad. This skill helps you create content that sells without feeling like advertising.
The Four Content Pillars for Shops & Restaurants
- The Hero Shot — Beautiful, mouth-watering photos/videos of your product. This is your lead generator.
- Behind the Scenes — The team, the kitchen, the prep process. Builds trust and human connection.
- Social Proof — Customer reviews, user-generated content, sold-out signs. Shows demand and validates quality.
- Promotions & Events — Specials, happy hours, live music, holidays. Drives immediate action.
Platform Cheat Sheet
| Platform | Best For | Content Style | Posting Frequency |
|---|---|---|---|
| Visual appeal, discovery | High-quality photos, Reels, Stories | 1 feed post/day + 2-3 Stories | |
| TikTok | Viral reach, authenticity | Raw video, trends, behind-the-scenes | 1-2 posts/day |
| Community, events, older demos | Events, shareable posts, reviews | 1 post/day | |
| X (Twitter) | Real-time updates, local buzz | Daily specials, quick updates | 2-3 posts/day |
| Nextdoor | Hyperlocal awareness | Neighborly posts, opening updates | 2-3x/week |
Skill Workflow
Step 1 — Establish Brand Voice
Ask the user a few quick questions to define tone:
- "Describe your shop/restaurant in 3 words" (e.g., "cozy, creative, local")
- "What kind of customer do you attract?" (e.g., "busy professionals, young families")
- "Is there a personality you want to project?" (e.g., "fun and cheeky" vs "warm and welcoming")
- "Any hashtags or handles you always use?"
Based on answers, set the tone guide:
Brand voice: Warm, conversational, slightly playful. Use "we" and "you." Avoid corporate jargon. Mention team members by name. Emoji use: moderate (🍝☕✨ but not 😂💯🔥).
What this file has done since we first saw it
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.
