skills: Instructions file for Codex

AGENTS.md

skills AGENTS.md is an instructions file for Codex, OpenCode from ShiroKSH/skills. It costs 145 tokens per session, scanned A, original, MIT.

Project instructions for a Roblox Studio skill and local connection used by coding agents. They describe how agents should inspect, plan, test, and safely modify Roblox game content.

In plain words
What is it for?
Use them when building Roblox maps or changing the skill, plugin, or local MCP connection. They guide dry runs, validation, file locations, naming, credentials, and Studio Undo safety.
Why use it?
They reduce the risk of breaking communication protocols, changing the wrong Roblox files, or creating unsafe game assets. They also require checks before changes are considered complete.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

skills 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 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.

What it actually says

AGENTS.md

  • Inspect repo first.
  • Plan before broad MCP/plugin/protocol changes.
  • Do not break protocol compatibility without migration notes.
  • Plugin and MCP server changes need a test or manual verification step.
  • Roblox/Luau changes must preserve local-first safety and Studio Undo.
  • Map build flow: prompt -> SceneSpec -> dry-run -> apply -> validate.
  • New maps go under Workspace/MapDrafts.
  • Workspace/AI_Generated accepted for migration only.
  • Do not edit user Workspace outside build roots without explicit permission.
  • Prefer multilevel named structures and unique instance names.
  • No Roblox credentials, .ROBLOSECURITY, or non-allowlisted external asset IDs.

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.
