npx skills add parcadei/Continuous-Claude-v3 --skill eigenvalues --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Eigenvalues ## When to Use Use this skill when working on eigenvalues problems in linear algebra. ## Decision Tree 1. **Compute Characteristic Polynomial** - det(A - lambda*I) = 0 - `sympy_compute.py charpoly "[[a,b],[c,d]]" --var lam` 2. **Find Eigenvalues** - Solve characteristic polynomial - `sympy_compute.py eigenvalues "[[1,2],[3,4]]"` 3. **Find Eigenvectors** - For each eigenvalue lambda: solve (A - lambda*I)v = 0 - `sympy_compute.py eigenvectors "[[1,2],[3,4]]"` 4. **Verify** - Check Av = lambda*v with `z3_solve.py prove` - Verify algebraic/geometric multiplicity ## Tool Commands ### Sympy_Eigenvalues ```bash uv run python -m runtime.harness scripts/sympy_compute.py eigenvalues "[[1,2],[3,4]]" ``` ### Sympy_Charpoly ```bash uv run python -m runtime.harness scripts/sympy_compute.py charpoly "[[a,b],[c,d]]" --var lam ``` ### Z3_Verify ```bash uv run python -m runtime.harness scripts/z3_solve.py sat "det(A - lambda*I) == 0" ``` ## Cognitive Tools Reference See `.claude/skills/math-mode/SKILL.md` for full tool documentation.

What does the eigenvalues skill do?
Problem-solving strategies for eigenvalues in linear algebra
How do I install it?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill eigenvalues --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From parcadei/Continuous-Claude-v3, a repository with 3,885 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
