Purpose & Capability
Name, description, and included Python code match: this is a local buffer recipe calculator and it does not request extra credentials, binaries, or system access beyond simple computation.
!
Instruction Scope
SKILL.md and the example code stay within buffer calculation scope, but the unit math in both the documentation and scripts is inconsistent with the code's use of mM and mL. The implementation computes 'moles' as (conc_mM * volume_mL / 1000) and then multiplies by molecular weight — this yields values 1000× too large (i.e., reports grams in the thousands instead of grams). This is a dangerous correctness bug for lab preparations and the SKILL.md formula/comments also show unit confusion.
✓
Install Mechanism
Instruction-only skill with a small local Python script; no install spec, no external downloads, and no packages pulled from untrusted URLs.
✓
Credentials
No environment variables, credentials, or config paths are requested — access scope is minimal and appropriate for the stated purpose.
✓
Persistence & Privilege
No elevated privileges requested; always=false and no persistent/system modifications are indicated.
What to consider before installing
Do NOT use this skill to prepare real laboratory buffers until the calculation bug is fixed. The script currently mixes mM and mL incorrectly and will produce component masses ~1000× too large (e.g., reporting kilograms instead of grams), which could cause dangerous experimental conditions. If you want to proceed only for testing/learning, run it in a non-lab context and double-check every calculation manually. Recommended fixes: convert volume to liters then convert mM to mol/L before computing grams. For example: - Correct approach (conceptual): volume_L = final_volume_ml / 1000.0; moles = (conc_mM / 1000.0) * volume_L; grams = moles * MW - Or an algebraic shortcut: grams = conc_mM * final_volume_ml * MW / 1_000_000 Ask the skill author to update the code and add unit tests (typical examples with known expected masses) and explicit unit annotations in outputs before using this in a real lab. If you rely on this for safety-critical preparations, prefer validated software or manual independent verification first.

Like a lobster shell, security has layers — review code before you run it.
