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 | $0.00030 | $0.00393 |
| Opus 5.5 | $0.00012 | $0.00157 |
| Sonnet 5.5 | $0.00006 | $0.00079 |
| Haiku 4.5 | $0.00003 | $0.00039 |
Grade A, and why
hayba-terrain-import-pass 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.
What it actually says
Import one terrain tile or bounded landscape
When to use
Use when a prepared heightmap must become a playable Unreal landscape. Record source resolution, height encoding, horizontal and vertical scale, target world bounds, intended paint layers, and memory/streaming budget. Work in an authorized scratch map first when scale or source data is uncertain.
Tool routing
- Read landscape_list and landscape_inspect to avoid duplicate terrain and establish the existing material, layout, bounds, and scale. Verify the source format and exact signature before landscape_import. That importer is the callable C++ route; the Python landscape readers do not sculpt or paint height data.
- Import once, then re-query with landscape_list and landscape_inspect. Check component layout and bounds against the plan, run landscape_layer_list and landscape_get_material, and set a confirmed material with landscape_set_material if needed. Use landscape_set_lod_settings only against a stated view-distance or performance target.
- Run scene_validate_physics and validator_run, capture an overview with editor_capture_viewport, and save the exact active map with level_save. Inspect saved, dirty, and verified status, then re-read landscape_list and landscape_inspect for the imported terrain. If import or persistence is uncertain, inspect the world before another import, mark the terrain unsaved, and route it to hayba-world-save-integrity; repeated creation can duplicate large terrain.
Evidence
Report source dimensions and scale, resulting landscape identity and bounds, layer/material readback, collision findings, save state, warnings, and observed visual seams. Imported geometry alone does not prove walkability, visual quality, runtime streaming, or target-platform memory; test those separately.
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.

hayba-terrain-import-pass is a skill published in the GitHub repository zajalist/hayba (13 stars, last pushed 3d ago), licensed MIT. It adds 30 tokens to every session and 393 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-04.
