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.
npx agentmods add commands/luckynee/unity-prefab-parser-mcp/unity-diffgit clone --depth 1 https://github.com/luckynee/unity-prefab-parser-mcpWhat it costs to keep this loaded
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 | $0.00018 | $0.00084 |
| Opus 5 | $0.00009 | $0.00042 |
| Sonnet 5 | $0.00004 | $0.00017 |
| Haiku 4.5 | $0.00002 | $0.00008 |
Grade A, and why
unity-diff 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 yesterday.
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
Load the unity-diff-workflow skill, then parse both Unity files with preset: "compact" and compare them.
Arguments: $ARGUMENTS
Highlight:
- Hierarchy changes (added/removed GameObjects)
- Added or removed components
- Changed field values
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-diff is a command published in the GitHub repository luckynee/unity-prefab-parser-mcp (2 stars, last pushed 3mo ago), licensed MIT. It adds 18 tokens to every session and 84 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.
