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 | $0.00016 | $0.00464 |
| Opus 5 | $0.00008 | $0.00232 |
| Sonnet 5 | $0.00003 | $0.00093 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
unity-package 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 7d 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
Package Management
Do not use Unity_RunCommand for package operations. Unity's MCP server exposes first-class package tools that cover every operation in this domain directly.
Routing
| Operation | Tool | Typical payload |
|---|---|---|
| List installed packages | Unity_PackageManager_GetData |
{ "installedOnly": true } (no packageID) |
| Check a specific package | Unity_PackageManager_GetData |
{ "packageID": "com.unity.cinemachine", "installedOnly": true } |
| List a package's versions | Unity_PackageManager_GetData |
{ "packageID": "com.unity.cinemachine", "installedOnly": false } |
| List a package's dependencies | Unity_PackageManager_GetData |
{ "packageID": "com.unity.timeline", "installedOnly": false } |
| Install a package | Unity_PackageManager_ExecuteAction |
{ "action": "Add", "packageID": "com.unity.cinemachine" } (optional version) |
| Remove a package | Unity_PackageManager_ExecuteAction |
{ "action": "Remove", "packageID": "com.unity.splines" } |
| Refresh / resolve | Unity_PackageManager_ExecuteAction |
{ "action": "Resolve" } |
| Embed a local copy | Unity_PackageManager_ExecuteAction |
{ "action": "Embed", "packageID": "com.unity.cinemachine" } |
| Import a package sample | Unity_PackageManager_ExecuteAction |
{ "action": "Sample", "packageID": "...", "sampleName": "..." } |
Notes
- Install / remove operations are asynchronous on Unity's side. If the tool returns a "pending" status, poll
Unity_PackageManager_GetDatawithinstalledOnly: truea few seconds later to observe the final state. - Package operations can trigger a Domain Reload. Expect transient server unavailability afterward; retry once.
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-package is a skill published in the GitHub repository batihandev/unity-mcp-skills (5 stars, last pushed 1mo ago), licensed MIT. It adds 16 tokens to every session and 464 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.
