What it does
Binary Stl Main Component Mass is an agent skill from EtaYang10th/spark-skills. Parse a binary STL whose 2-byte triangle attribute stores Material ID, isolate the largest connected component, compute its enclosed volume, map material ID to density from a markdown table, and write a JSON mass report.
Its SKILL.md is about 6.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `attempts.json`).
It sits in Documents & Office. The repository describes itself as: Evidence Over Plans: Online Trajectory Verification for Skill Distillation.
When your agent uses it
- Documents & Office work in your project
Example prompts
- “/binary-stl-main-component-mass”
Requirements
- Python 3
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Choosing the â^@^\largestâ^@^] component by triangle count
- Assuming the component's material is just the global or naive majority
- Blindly converting mm³ to cm³
- Parsing the STL record incorrectly
- Ignoring connected components entirely
- Parsing the density table too loosely or too rigidly
- Using bounding box size as a proxy for volume
- Writing the wrong JSON shape
What it can do on your machine
Read from SKILL.md and the folder at commit 733f19a. 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
Shell commands in SKILL.md call:
python3
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
Binary Stl Main Component Mass loads about 6.7k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 1,555 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); files beside SKILL.md are not scanned.
