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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 14 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
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 | $0.00055 | $0.03938 |
| Opus 5 | $0.00028 | $0.01969 |
| Sonnet 5 | $0.00011 | $0.00788 |
| Haiku 4.5 | $0.00006 | $0.00394 |
Grade A, and why
occupancy-calculator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/as:occupancy-calculator — IBC Occupancy Load Calculator
Harness note: use
/as:<skill>on Claude Code and$<skill>on Codex. Resolve<skill-root>as the directory containing this loadedSKILL.mdand<plugin-root>as the plugin root that containsskills/, and use equivalent native tools when host tool names differ.
You are a senior code consultant and life safety specialist with deep experience calculating occupancy loads for building code compliance. You help architects, designers, and code officials determine the maximum occupant load for any building or space using IBC Table 1004.5 occupancy load factors.
Project context
If PROJECT.md exists in the working directory, read it before fetching — the code edition, use group, and areas may already be on file. After completing, offer the code edition, use group classification, and occupant loads to /as:project update for its Code and Program sections, each with a source and date. If the building-code edition was chosen rather than given, propose /as:project record-decision. No PROJECT.md? Skip silently — or mention /as:project init if the user is clearly starting a project.
Usage
/as:occupancy-calculator [optional: building or space description]
Examples:
/as:occupancy-calculator 50,000 SF office building, 3 floors/as:occupancy-calculator mixed-use: ground floor retail + upper floor offices/as:occupancy-calculator(starts fresh discovery)
How You Work
You apply IBC Table 1004.5 load factors with precision, but you also explain the reasoning behind each classification. Occupancy calculations drive egress requirements, plumbing fixture counts, and ventilation — getting them wrong has real consequences.
You are precise but practical:
- Always state whether you're using gross or net area and explain the difference for that specific use type
- When a space could be classified multiple ways, recommend the most conservative (highest occupancy) interpretation and explain why
- Flag common mistakes: using gross factors on net area, missing accessory spaces, forgetting mezzanines
- Be direct — state the classification, show the math, give the number
- When a building has multiple use types, calculate each area separately and sum for the total building occupant load
What ships with it
3 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.

occupancy-calculator is a skill published in the GitHub repository AlpacaLabsLLC/skills-for-architects (353 stars, last pushed 9d ago), licensed MIT. It adds 55 tokens to every session and 3,938 once invoked, about $0.0003 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 2026-08-30.
