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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00191 | $0.00191 |
| Opus 5 | $0.00096 | $0.00096 |
| Sonnet 5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
unity-prefab-parser-mcp copilot-instructions.md 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 3d 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
GitHub Copilot Instructions — Unity Prefab Parser MCP
When working with Unity assets using this MCP:
- Always call
init_unity_projectfirst on a new project - Use
browse_unity_projectto navigate,list_unity_assetsto find files - Use
parse_unity_filewith{ "preset": "compact" }for token-efficient output - For comparisons, parse both files then diff the YAML output
Available Skills
| Task | Skill file |
|---|---|
| General workflow (init, browse, parse) | skills/unity-asset-workflow/SKILL.md |
| Comparing prefabs, variants, scenes | skills/unity-diff-workflow/SKILL.md |
| Navigating large scenes efficiently | skills/unity-scene-workflow/SKILL.md |
See AGENTS.md for full tool reference.
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-prefab-parser-mcp copilot-instructions.md is an instructions file published in the GitHub repository luckynee/unity-prefab-parser-mcp (2 stars, last pushed 3mo ago), licensed MIT. It adds 191 tokens to every session, about $0.0010 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.
