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 | $0.00079 | $0.02970 |
| Opus 5.5 | $0.00032 | $0.01188 |
| Sonnet 5.5 | $0.00016 | $0.00594 |
| Haiku 4.5 | $0.00008 | $0.00297 |
Grade A, and why
unity-cli-contract 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity CLI contract
Three artifacts claim to describe the one unity binary on this machine — the skill copy installed at
~/.claude/skills/unity-cli, that same skill at GitHub@main, and the binary itself. No two of them agree,
and the disagreement is not one simple lag: it runs in both directions at once, so neither "my reference
lists it" nor "my reference says nothing about it" settles anything at all.
| Axis | Direction of drift | What it costs you |
|---|---|---|
| Installed docs → GitHub@main | Installed sits one release behind, pinned to the CLI release it was captured at (SK:439). Whole pages are missing locally: no version-control reference file, no sandboxed-agent section, no ci init, no config get/set/list/unset, no auth consumers/revoke. |
A hole in the copy you loaded is not a hole in the product. |
| GitHub@main → binary | GitHub sits one release ahead. It documents surfaces the binary may not carry — at one capture point unity version, test --affected*, install --list-modules and plugin changelog all failed to answer — but which four drift with the build, so probe each on the binary you actually have rather than trusting this list. |
A user quoting Unity's public documentation at you is usually right about the product and wrong about your binary. Do not argue with the citation; probe the binary. |
| Installed docs ↔ binary | Both directions at once, because a skill refresh swaps one of these two artifacts for the other. Binary-ahead today: vcs and close answer on the binary and are named nowhere in the installed docs. Docs-ahead after any refresh: the four GitHub-only surfaces above land in your reference without landing on your binary. And --detach / job status|wait|cancel sit on the binary undocumented in either written copy. |
Silence in your copy is not absence on the binary. In the T3.2 baseline (three reps, 2026-09-14/15), two of the three read that silence as a denial and told the user that a capability this binary ships "does not exist at all". |
No document is authority over the binary, in either direction. Probe first.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-cli-contract is a skill published in the GitHub repository Nice-Wolf-Studio/unity-claude-skills (40 stars, last pushed 1mo ago), licensed MIT. It adds 79 tokens to every session and 2,970 once invoked, about $0.0003 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 2026-09-16.
