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 | $0.03014 | $0.03014 |
| Opus 5 | $0.01507 | $0.01507 |
| Sonnet 5 | $0.00603 | $0.00603 |
| Haiku 4.5 | $0.00301 | $0.00301 |
Grade A, and why
unity-cli-loop AGENTS.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 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.
How it starts
The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architecture Overview
This project provides a CLI tool (uloop) that communicates with Unity Editor over local IPC
(a Unix domain socket on macOS/Linux, a named pipe on Windows — not TCP).
AI agents interact with Unity through uloop CLI commands (e.g., uloop get-logs, uloop compile).
The Unity Editor side hosts a local project IPC server that accepts short-lived CLI command sessions.
Repository Map
Directory-level responsibilities. Kept deliberately coarse — check the directory itself for file-level detail.
Packages/src/— the Unity package (C#). Each first-party tool lives inEditor/FirstPartyTools/<Tool>/with its implementation and agent skill (Skill/SKILL.md, optionalSkill/references/).Packages/src/Editor/CliOnlyTools~/<Tool>/Skill/— skills for CLI-only commands (launch, pause-point, etc.) that have no Unity tool class. Tilde-suffixed folders are ignored by Unity, so files there need no.meta; files underFirstPartyToolsdo (runuloop compileto let Unity generate them).Assets/— the development/test Unity project, including custom-command samples underAssets/Editor/CustomCommandSamples/.Assets/RegressionHarness/<TrapName>/— permanent manual repro scenes for verification-round "traps" (pause-point, simulate-keyboard, physics callbacks, etc.), paired with a driver script underscripts/regression-harness-<trap-name>.sh. Seedocs/regression-harness.md.cli/dispatcher/— the globally installeduloopentry command (also ownsuloop skills installand skill syncing).cli/project-runner/— the per-project CLI runner that talks to the Unity-side IPC server.cli/common/— Go modules shared by dispatcher and project runner. Tool parameter schemas live incli/common/tools/default-tools.json; skill discovery incli/common/skillscan/.cli/release-automation/— Go logic backing GitHub Actions release/CI workflows.tools/UnityCliLoop.DeadCodeScanner/— the C# dead-code scanner described below.docs/— reference docs for the rules in this file.docs/adr/holds architecture decision records: read the relevant one before reopening a settled design question, and note its stated reversal condition rather than relitigating from scratch.dist/— locally built development binaries (dist/darwin-arm64/uloop, etc.); never committed..claude/,.agents/— generated skill copies; never edit directly (see Generated Skill Files)..uloop/— runtime state and command outputs (screenshots, test results, hierarchy dumps).
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-loop AGENTS.md is an instructions file published in the GitHub repository hatayama/unity-cli-loop (522 stars, last pushed yesterday), licensed MIT. It adds 3,014 tokens to every session, about $0.0151 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 2026-08-30.
