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 | $0.00095 | $0.01737 |
| Opus 5 | $0.00048 | $0.00869 |
| Sonnet 5 | $0.00019 | $0.00347 |
| Haiku 4.5 | $0.00010 | $0.00174 |
Grade A, and why
placentia-adu 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Placentia ADU — City Regulatory Skill
This skill contains Placentia's city-level ADU rules — the local ordinance, development standards, permit process, fees, and fire/zoning requirements that supplement or override California state ADU law.
How this skill relates to state law: The california-adu skill covers the state floor (Gov. Code §§ 66310-66342). This skill covers what Placentia adds, matches, or potentially conflicts with. Always load state law context first, then layer this skill on top for city-specific questions.
What this covers: Placentia Municipal Code Chapter 23.73, Title 20 building codes, Title 23 zoning, Title 18 fire code, permit process, fees, and local development standards.
What this does NOT cover: State-level ADU law (use california-adu skill), federal requirements, or project-specific engineering.

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.
