What it does
General Chemical Pricing is an agent skill from learningmatter-mit/AtomisticSkills. Retrieves averaged elemental prices and provides direct vendor purchase links for elements and precursor compounds.
Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `examples/lithium-carbonate/README.md` and `scripts/get_pricing.py`).
It works with Wikipedia. The repository describes itself as: Integrating AtomisticSkills into Agentic IDEs (Cursor, Claude Code, Codex, Google Antigravity, Hermes Agent, etc). The licence is MIT.
Example prompts
- “Use the general-chemical-pricing skill to retrieve averaged elemental prices and provides direct vendor purchase links for elements and precursor…”
- “/general-chemical-pricing”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 6257444. 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), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
en.wikipedia.orgpubchem.ncbi.nlm.nih.govgithub.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
General Chemical Pricing loads about 566 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 220 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.

General Chemical Pricing
Goal
To programmatically query averaged bulk commodity prices for pure chemical elements (in USD/kg) and to retrieve direct chemical vendor links for ordering specific precursor compounds or elemental forms.
Instructions
1. Get Pricing and Vendor Links
Use this script to search for the pricing details of a given element or chemical compound. The script aggregates Wikipedia's USGS elemental data with PubChem's registered supplier vendor lists.
${CLAUDE_SKILL_DIR}/../../venv/run cpu python ${CLAUDE_SKILL_DIR}/scripts/get_pricing.py <Query Name or Symbol>Parameters:
<Query Name or Symbol>: The name, symbol, or full compound name (e.g., "Lithium", "Li", "Lithium carbonate", "Li2CO3"). Ensure multi-word compounds are wrapped in quotes (e.g.,"Lithium carbonate").
Examples
See examples/lithium-carbonate/README.md for a complete run of querying elemental lithium alongside a molecular precursor.
Constraints
- Environments: The script requires the
cpuenvironment because it uses standard requests, beautifulsoup4, and pubchempy libraries. Each code block MUST specify the environment. - Price Precision: Elemental bulk prices presented are averaged and highly dependent on market fluctuations and the reference year (scraped dynamically from Wikipedia's USGS Mineral Commodity list).
- Vendor Links: For compounds, live price points are not freely accessible via unauthenticated APIs. The skill provides a robust PubChem URL that aggregates active supplier links where live pricing can be interactively observed.
