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 | $0.00062 | $0.00291 |
| Opus 5 | $0.00031 | $0.00146 |
| Sonnet 5 | $0.00012 | $0.00058 |
| Haiku 4.5 | $0.00006 | $0.00029 |
Grade A, and why
physics-review 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 4d 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
Physics Review
Post-implementation reviewer for Godot physics code. Checks against known gotchas that LLMs consistently get wrong.
When to trigger
After physics-related code is written or modified. Look for:
- Physics body nodes (StaticBody2D, RigidBody2D, CharacterBody2D, Area2D)
- Collision layer/mask assignments
- Physics callbacks (
body_entered,body_exited,area_entered,area_exited) _physics_process()with velocity/damping logic- Objects spawned near Area2D
Review process
- Read
gotchas.md - Scan the implemented code against each gotcha
- For each hit:
- Cite the gotcha ID (e.g. G1)
- Show the offending code
- Provide the fix
- If no hits, report clean
- Optionally run
checklist.mdstatic checks for automated verification
When you need specific API details, delegate to the godot-api skill.
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.

physics-review is a skill published in the GitHub repository valkor-ai/loom (949 stars, last pushed 18d ago), licensed Apache-2.0. It adds 62 tokens to every session and 291 once invoked, about $0.0003 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.

Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
assets-prefab-save
Save the currently opened prefab edit stage back to its prefab asset without exiting the stage. Pair with 'assets-prefab-open' to enter the edit mode first.
mobile-games
Mobile game development principles. Touch input, battery, performance, app stores.
influence-psychology
Apply the seven principles of ethical persuasion (reciprocity, commitment, social proof, authority, liking, scarcity, unity) to product design, copy, and sales. Use when the user mentions "social proof", "persuasive copy", "why users dont convert", "ethical persuasion", "reciprocity", "scarcity tactics", "commitment…

Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
