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 | $0.00026 | $0.01481 |
| Opus 5 | $0.00013 | $0.00740 |
| Sonnet 5 | $0.00005 | $0.00296 |
| Haiku 4.5 | $0.00003 | $0.00148 |
Grade A, and why
unity-perception 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 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.
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.

Unity Perception Skills
Overview
Use this module for read-only scene and project analysis. It is available in Semi-Auto by default.
Common Mistakes
DO NOT (common hallucinations):
perception_analyze,perception_scan, andperception_describedo not existscene_contextis noteditor_get_context: it exports hierarchy/components/references, while editor context focuses on current editor statescene_analyze,scene_health_check,scene_contract_validate,scene_component_stats,scene_find_hotspots, andproject_stack_detectbelong to this module even if the prefix looks likescene_*orproject_*
Routing:
- Current selection/play-mode/editor state ->
editor_get_context - Object search by name/path ->
scene_find_objectsorgameobject_find - Script dependency closure ->
script_dependency_graph

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.

unity-perception is a skill published in the GitHub repository batihandev/unity-mcp-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 1,481 once invoked, about $0.0001 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 2026-08-31.
