Roblox Characters

What it does

When your agent uses it

• Character scripts break after respawn
• Cache stale Humanoids
• Control movement
• Load AnimationTracks

Example prompts

• “/roblox-characters”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Inspect the character contract. Check avatar settings, StarterCharacter,
2. 2Separate scopes. Player-scope state survives respawn; character-scope state does not. Put
3. 3Bind existing and future characters. Connect CharacterAdded, then bind player.Character
4. 4Resolve required components defensively. Wait with a timeout where replication warrants it;
5. 5Choose movement ownership. Use Humanoid movement for standard avatars; use
6. 6Own animation lifecycle. Load via the rig's Animator; store tracks/connections; use named
7. 7Verify lifecycle stress. Spawn, die, reset, rapid-respawn, swap rig if supported, equip/drop

What it can do on your machine

Read from SKILL.md and the folder at commit 0a70cfc. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are lua).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • create.roblox.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Roblox Characters loads about 2.2k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 732 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~114

When it runs · the whole SKILL.md, loaded when a task matches

~2.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Build respawn-safe Roblox character systems around Players, CharacterAdded/CharacterRemoving, Humanoid, HumanoidRootPart, Animator, R6/R15 rigs, movement, animations and markers, death, tools, accessories, ownership, and custom characters. Use when character scripts break after respawn, cache stale Humanoids, control movement or velocity, load AnimationTracks, handle death, equip Tools, modify avatars, or support custom player rigs.
