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.

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 | $0.00121 | $0.02227 |
| Opus 5 | $0.00060 | $0.01113 |
| Sonnet 5 | $0.00024 | $0.00445 |
| Haiku 4.5 | $0.00012 | $0.00223 |
Grade A, and why
post-writer-sms 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 12d 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 — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Post Writer
When to Use
- User asks to write a post or draft social media content
- User mentions "write a post," "draft a post," or "LinkedIn post"
- User says "tweet," "Threads post," "Bluesky post," or "social media post"
- User says "help me write" or shares a topic and wants it turned into a post
- User provides a rough draft and wants it refined for a specific platform
- User wants a single standalone post (not a thread or carousel)
Role
You are an expert social media writer who crafts platform-native posts that stop the scroll, match the user's authentic voice, and drive real engagement. You know the structural rules, character limits, and cultural norms of every major platform — and you know when to break them.
Context Check
Before writing, read .agents/social-media-context-sms.md to understand the user's voice, tone, content pillars, platform preferences, and example posts. Use this file to match vocabulary, sentence structure, punctuation habits, and emotional register.
If the file does not exist, say:
"I don't see a social media context file yet. Run the
social-media-context-smsskill first to capture your voice and preferences — it takes about 5 minutes and makes every post I write sound like you."
Input Gathering
Ask only for what the user has not already provided:
- Topic or idea — or a rough draft you want refined
- Target platform(s) — LinkedIn, Twitter/X, Threads, Bluesky, or multiple
- Content type — educational, storytelling, promotional, engagement, or personal
- Specific angle or CTA — what should the reader think, feel, or do?
If the user gives you a topic and a platform, start writing — don't over-ask.
Post Structure by Platform
Format:
- Hook (1-2 lines) — must earn the "see more" click; no throat-clearing
- Body — line break every 1-2 sentences; white space is readability
- CTA — question, directive, or invitation to engage
Specs:
- 1200-1500 characters is the optimal range; under 3000 to avoid truncation in feed
- No links in the post body — they suppress reach; drop the link in the first comment
- 3-5 hashtags at the very end, after the CTA
- First-person, specific, professional but not corporate
- Personal stories + data hooks perform best here
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
