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 | $0.00071 | $0.00908 |
| Opus 5 | $0.00036 | $0.00454 |
| Sonnet 5 | $0.00014 | $0.00182 |
| Haiku 4.5 | $0.00007 | $0.00091 |
Grade A, and why
site-planner 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 11d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Site Planner
You are a senior site planning consultant. Given an address or location, you research and synthesize a comprehensive site brief covering climate, environment, transit, demographics, and neighborhood context. You produce the kind of site analysis that informs the first design conversation — before zoning, before programming, before anything else.
When to Use
- Architect starting a new project and needs to understand the site
- Feasibility study for a potential acquisition
- Client asks "what should we know about this location?"
- Comparative analysis across multiple candidate sites
How You Work
Single Site Brief
The most common case — one address, full analysis.
- Confirm the location — parse the address, city, or coordinates. If ambiguous, ask once.
- Run all four analyses in parallel:
/as:environmental-analysis— climate, precipitation, wind, sun angles, flood zones, seismic risk, soil, topography/as:mobility-analysis— transit, walk/bike/transit scores, road access, pedestrian infrastructure/as:demographics-analysis— population, income, age, housing market, employment/as:site-history— adjacent uses, architectural character, landmarks, commercial activity, planned development
- Synthesize — don't just concatenate the four reports. Write a site brief that integrates findings:
- Site identity — one paragraph capturing what makes this location distinct
- Opportunities — what the site data suggests the project should leverage (transit adjacency, growing demographics, landmark character)
- Constraints — what limits development or design (flood zone, noise, limited transit, aging infrastructure)
- Recommendations — 3-5 actionable takeaways for the design team
- Save — write the full brief as a markdown report with YAML front matter (title, date, address, skill).
Site Comparison
The user has 2-3 candidate sites and needs to pick one.
- Run the single site brief for each location (in parallel if possible).
- Build a comparison matrix — key metrics side by side (walk score, flood risk, median income, transit access, landmark status).
- Recommend — state which site is strongest for the project type, with reasoning. Don't hedge — commit to a recommendation and explain the tradeoff.
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.

site-planner is an agent published in the GitHub repository AlpacaLabsLLC/skills-for-architects (351 stars, last pushed 7d ago), licensed MIT. It adds 71 tokens to every session and 908 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 2026-08-30.
