  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Ceres Core is an agent skill from AkiKurisu/Ceres. Build or extend Ceres runtime services, including pooling, events, configs, resources, data-driven utilities, schedulers, serialization, collections, R3, tasks, and modules.

Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/data-and-reactive.md` and `references/runtime-services.md`).

The repository describes itself as: A Unity framework designed with visual scripting and flexible workflows. The licence is MIT.

Example prompts

  • “/ceres-core”

What it can do on your machine

Read from SKILL.md and the folder at commit 0f37dc4. 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.

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

  • Network

    No URLs in SKILL.md.

    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

Ceres Core loads about 230 tokens when it runs, and up to ~997 if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 74 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~230
With references · SKILL.md plus every file in references/, read only if the agent opens them
~997

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

Build or extend Ceres runtime services, including pooling, events, configs, resources, data-driven utilities, schedulers, serialization, collections, R3, tasks, and modules.

Ceres Core

Inspect Packages/com.kurisu.ceres/Runtime/Core and the nearest existing consumer before choosing an abstraction. Keep reusable runtime APIs in Ceres; do not introduce dependencies on Graph, Flow, Gameplay, or UnityEditor.

References

  • Read runtime-services.md for pooling, events, configs, resources, tasks, and modules.
  • Read data-and-reactive.md for data-driven types, schedulers, serialization, collections, and R3 integration.

Use public developer documentation for conceptual usage, then confirm signatures and lifecycle behavior in current source. Avoid copying API inventories into new documentation.
