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 | $0.00072 | $0.01207 |
| Opus 5 | $0.00036 | $0.00603 |
| Sonnet 5 | $0.00014 | $0.00241 |
| Haiku 4.5 | $0.00007 | $0.00121 |
Grade A, and why
fair-housing-overlay 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fair Housing Overlay
The compliance foundation for every other skill in this repo. Load this and Claude will refuse to write copy that violates Fair Housing, TCPA, or MLS data-quality rules — even if the surrounding prompt forgets to mention them.
When to use this skill
Always. Real estate is one of the most-regulated content categories in marketing. The Fair Housing Act, the Telephone Consumer Protection Act, state real-estate-license rules, and MLS data-quality penalties all overlap. A single offhand line in a listing description, social post, or email can trigger a complaint.
This skill is the always-on safety net. Load it once, and every skill that runs on top of it produces compliant output by default.
What it does
Adds four rule sets to whatever prompt you run alongside it:
Rule Set 1 — Fair Housing Act (federal, plus state extensions)
The skill refuses to generate any copy that:
- References schools by name, ranking, district, or perceived quality
- Describes a neighborhood by demographic (race, religion, family status, national origin, disability, gender identity, sexual orientation, source of income — covered classes vary by state, this skill uses the union of all federal + state-protected classes)
- Implies steering ("perfect for young professionals", "great for retirees", "ideal for families with kids", "safe neighborhood for kids", "walkable to your church")
- Uses coded language ("up-and-coming", "exclusive", "private", "tight-knit community", "family-friendly")
- Mentions any community amenity in a way that implies a protected-class preference
The skill rewrites these patterns into compliant alternatives:
- Schools → location/commute or specific drive times to employers
- "Family-friendly" → specific objective amenities (parks, sidewalks, lot size)
- "Quiet neighborhood" → "low-traffic street" (objective, measurable)
- "Safe area" → no replacement; this phrase is forbidden because safety perception varies by demographic
Rule Set 2 — TCPA (Telephone Consumer Protection Act)
What ships with it
2 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.

fair-housing-overlay is a skill published in the GitHub repository TheProsperityAgent/prosperity-real-estate-skills (8 stars, last pushed 1mo ago), licensed MIT. It adds 72 tokens to every session and 1,207 once invoked, about $0.0004 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.
