What it does
Geologist Aspect 300 is an agent skill from naikangyuan/Aspect_Yuan.skill. Use AspectYuan or geologist-aspect-300 to help geologists reproduce ASPECT geodynamics papers and build ASPECT models with explicit version control, including Kaili, ONeill, and Gernon paper-code workflows, paper reproduction profiles, DOI/code repository/version/commit detection, ASPECT installation planning, downloaded article code, .prm parameter file generation, cookbook and benchmark adaptation, beginner teaching models, plugin development, material model setup, deep-shallow coupling, subduction, mantle…
Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 163 other files, including scripts, reference files and assets (for example `README.md`, `agents/openai.yaml` and `aspect_yuan/__init__.py`).
It sits in Agent Workflows, covering Hooks and plugins and Git workflow.
When your agent uses it
- Tasks that involve Hooks and plugins
- Tasks that involve Git workflow
Example prompts
- “/geologist-aspect-300”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Paper reproduction system: identify the target paper, DOI, supplement, code repository, ASPECT version, git tag/commit/branch, external…
- Version and installation system: choose whether to use the user's existing ASPECT, install a tagged release, build a paper-specific…
- PRM modeling system: learn from local ASPECT cookbooks, benchmarks, tests, and documentation; draft .prm parameter files; explain existing…
- Plugin development system: identify the right ASPECT plugin type; generate small plugin skeletons or edits; explain how the plugin is…
- Aspect_Yuan CLI system: use scripts/aspect-yuan for beginner one-command lessons, GeoSpec geology.yaml model intent files, model…
What it can do on your machine
Read from SKILL.md and the folder at commit a10febd. 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
Ships 1 file in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
bash
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
Geologist Aspect 300 loads about 3.6k tokens when it runs, and up to ~82k if it reads all its reference files. Until then it costs about 177 tokens; SKILL.md has 1,503 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,503 words (~3,631 tokens).
“This skill is for ordinary geologists using ASPECT, not ASPECT core developers. Its purpose is to reproduce published ASPECT-based geodynamics studies first, then translate a geological science question into a runnable, explainable, and modifiable ASPECT model.”
