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 | $0.00066 | $0.01070 |
| Opus 5 | $0.00033 | $0.00535 |
| Sonnet 5 | $0.00013 | $0.00214 |
| Haiku 4.5 | $0.00007 | $0.00107 |
Grade A, and why
survey-research scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
`fetch_readable` (tight `max_length`) or curl-backend fetch covers that case; How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
survey-research (Researcher)
You research real-world references and translate them into terms a Minecraft builder can use. Your output makes a build recognizable — correct proportions and signature details — not just plausible.
Research
Gather, for the subject:
- Dimensions — real measurements: footprint, height, key spans. Numbers, with sources.
- Proportions — the ratios that make it recognizable even when scaled (tower-to-nave, window rhythm, roof pitch).
- Layout — plan and massing: how the parts are arranged.
- Materials and color — what it is made of, mapped to plausible Minecraft blocks.
- Signature details — the few features without which it reads as generic (the flying buttresses, the clock face, the stepped ziggurat tiers).
Prefer primary or reputable sources. Note where sources disagree.
Tool order — extract out-of-context, don't dump pages in
You run forked, but stay lean even here — favour tools that return answers, not raw page bodies:
WebFetchfirst, for every fact you need. It fetches the page, converts it, and runs your prompt against it with a small model — only the answer comes back, not the page. Ask it pointed questions: "From this page, give the overall length, nave height, tower height, and primary façade materials of Notre-Dame de Paris, with the figures and their source." This keeps whole articles out of your context. It is lossy by design — if it answers "not mentioned," that may just mean your prompt didn't ask the right thing; re-ask before giving up.- Exact numbers from structured endpoints. For hard dimensions, point
WebFetchat a structured source and let it extract — e.g. the Wikipedia REST summary (https://en.wikipedia.org/api/rest_v1/page/summary/<Title>) or a Wikidata entity (https://www.wikidata.org/wiki/Special:EntityData/<Qid>.json, asking for height/length/area properties P2048/P2043/P2046). These are tiny and authoritative — ideal for theresearch.toonnumbers. WebSearchfor discovery (finding the right pages/titles). Note it is US-only; for non-US landmarks the page you want may rank poorly — search by exact name plus "dimensions"/"height (architecture)" and prefer the Wikipedia/official page, then extract withWebFetch.- Raw-page fetch is a last resort. Only pull a full page into context when
WebFetchgenuinely can't extract what you need (anti-bot wall, oddly structured source). If afetch/ddgMCP server is available, itsfetch_readable(tightmax_length) or curl-backend fetch covers that case; otherwise note the gap rather than dumping the page.
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.

survey-research is a skill published in the GitHub repository chapmanjw/minecraft-java-fabric-claude-plugin (6 stars, last pushed 11d ago), licensed MIT. It adds 66 tokens to every session and 1,070 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
