Before you install
Read from the skill's files at the directory's October 19, 2026 snapshot: what ships with it, what its code reads, and the terms it is published under.
- Bundled scripts: 3 script files (3 Python). Your agent may run them, so read them first.
- Tool permissions requested:
Read, Bash, Write, Grep, Glob(theallowed-toolsfield of SKILL.md). - License: Apache-2.0, an open-source or open-content license.
Install differentiation-schemes
The skills CLI works with Claude Code, Codex, Cursor and other agents; the other routes copy the folder by hand.

How the author describes it
Select and apply numerical differentiation schemes for PDE and ODE discretization — generate finite-difference stencils at arbitrary order and accuracy, choose between central, upwind, compact (Pade), and spectral methods, handle boundary stencils, and estimate truncation error scaling. Use when discretizing spatial derivatives, picking a scheme for advection- or diffusion-dominated problems, building custom stencils for nonstandard operators, or comparing dispersion and dissipation properties of candidate schemes, even if the user just says "how do I approximate this derivative" or "my solution is too diffusive."
From the description field of SKILL.md. Agents read this line to decide when to load the skill.

differentiation-schemes passes the required frontmatter check and all seven graded checks, which cover the SKILL.md format, a declared license and a commit in the last year. Those checks earn 56 of the score’s points; the rest come from description quality, instruction depth, bundled files, maintenance and curated-list citations. How the score works.
