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 | $0.00094 | $0.01678 |
| Opus 5 | $0.00047 | $0.00839 |
| Sonnet 5 | $0.00019 | $0.00336 |
| Haiku 4.5 | $0.00009 | $0.00168 |
Grade A, and why
roblox-characters 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 2d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Roblox characters
Treat a Player as the durable identity and each Character as a replaceable session with its own
references, connections, animation tracks, and cleanup. Targets Roblox's rolling platform APIs.
When to use
- Use for player-character lifecycle, Humanoid state/movement, rigs, animations, tools, accessories, custom characters, death, or respawn defects.
- Use whenever code stores a Character/Humanoid/root reference longer than one spawn.
When not to use: general physics queries and constraints belong to roblox-physics; remote
trust belongs to roblox-networking; camera logic belongs to camera-systems.
Workflow
- Inspect the character contract. Check avatar settings,
StarterCharacter,StarterCharacterScripts,CharacterAutoLoads, R6/R15 support, existing Animate/controller scripts, tools, tags, collision groups, and server/client ownership. - Separate scopes. Player-scope state survives respawn; character-scope state does not. Put character connections/tracks/resources in one cleanup scope and destroy it on removal.
- Bind existing and future characters. Connect
CharacterAdded, then bindplayer.Characterif present. Do not assume event subscription alone sees a character that already spawned. - Resolve required components defensively. Wait with a timeout where replication warrants it;
validate
Humanoid, root,Animator, and rig assumptions. Abort if that character is no longer current before applying delayed work. - Choose movement ownership. Use Humanoid movement for standard avatars; use
AssemblyLinearVelocity,BasePart:ApplyImpulse(), or aLinearVelocity/AlignPositionconstraint only for mechanics that need physical control. Keep gameplay authority and network ownership implications explicit. - Own animation lifecycle. Load via the rig's
Animator; store tracks/connections; use named markers for gameplay timing only with server validation; stop/disconnect on character cleanup. - Verify lifecycle stress. Spawn, die, reset, rapid-respawn, swap rig if supported, equip/drop tools, leave during setup, and run with at least two players when character interactions matter.
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.

roblox-characters is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (952 stars, last pushed 2d ago), licensed Apache-2.0. It adds 94 tokens to every session and 1,678 once invoked, about $0.0005 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 2026-09-09.
Other skills, from other repositories
assets-get-data
Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via paths or viewQuery. Use 'assets-find' to find the asset first.
gameobject-set-parent
Reparent a batch of GameObjects under a new parent in the currently opened Prefab or active Scene. Per-item failures are reported in the returned status string instead of aborting the batch. Use 'gameobject-find' to locate the GameObjects first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
profiler-save-data
Save a snapshot of profiler-derived stats (status + memory + rendering + script + frame capture) to a JSON file. Built-in Unity APIs only.
assets-shader-list-all
List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid shaderName for 'assets-material-create'.
profiler-stop
Disable Unity's runtime profiler. Idempotent — calling when already disabled returns the current disabled state.
