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 | $0.00130 | $0.00912 |
| Opus 5 | $0.00065 | $0.00456 |
| Sonnet 5 | $0.00026 | $0.00182 |
| Haiku 4.5 | $0.00013 | $0.00091 |
Grade A, and why
housing-copywriter 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copywriting Guardrails
This skill prevents AI-sounding copy and produces authentic, human writing.
Core Principles
1. Specificity Over Generality
- Replace abstract claims with concrete details
- Use real numbers, names, and examples
- "Increases productivity" → "Saves 3 hours per week on invoicing"
2. Cut Ruthlessly
- Delete filler words and throat-clearing
- One strong sentence beats three weak ones
- If a word adds nothing, remove it
3. Write Like You Talk
- Read it aloud—if it sounds stiff, rewrite it
- Contractions are fine. Sentence fragments too.
- Vary sentence length. Short punches. Then a longer one to change the rhythm.
4. Show, Don't Announce
- Don't say "We're excited to announce"—just announce it
- Don't say "It's important to note"—just note it
- Don't describe what you're doing; do it
5. Earn Every Adjective
- Strip all adjectives, then add back only the essential ones
- "Our innovative, cutting-edge, revolutionary platform" → "Our platform"
- Let nouns and verbs do the work
Before Delivering Copy
Self-check:
- Did I use any words from the avoid list? → Check
references/avoid-list.md - Could a reader guess this was AI-written? What gives it away?
- Is there a single weak sentence I'm protecting? Cut it.
- Read the first sentence—would I keep reading?
Tone Calibration
Match the context:
- Casual/social: Write like texting a smart friend
- Professional/B2B: Clear and direct, not corporate-speak
- Luxury/premium: Confident and understated, not breathless
- Startup/tech: Energetic but not try-hard
When unsure, err toward conversational and direct.
Reference
See references/avoid-list.md for banned words, phrases, and patterns with alternatives.
Pro-Housing Messaging
When writing housing advocacy, zoning reform, or parking flexibility content, follow these additional guidelines. See references/pro-housing-messaging.md for complete frameworks, terminology tables, and top-performing message examples.
What ships with it
4 files 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.
- 8d ago First seen · 91 lines · 130 tokens per session scan A 8dd3d8229fc5
housing-copywriter is a skill published in the GitHub repository MisterClean/claude-plugins (3 stars, last pushed 7mo ago), licensed MIT. It adds 130 tokens to every session and 912 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
