Vector Spaces
When to Use
Use this skill when working on vector-spaces problems in linear algebra.
Decision Tree
1. **Check Subspace**
- Contains zero vector?
- Closed under addition?
- Closed under scalar multiplication?
- Verify with `z3_solve.py prove`
2. **Linear Independence**
- Set up Ax = 0 where columns are vectors
- `sympy_compute.py nullspace "A"`
- Trivial nullspace = independent
3. **Basis and Dimension**
- Find spanning set, remove dependent vectors
- `sympy_compute.py rref "A"` to find pivot columns
- Dimension = number of pivots
4. **Change of Basis**
- Find transition matrix P
- New coords = P^(-1) * old coords
- `sympy_compute.py inverse "P"`
Tool Commands
Sympy_Nullspace
uv run python -m runtime.harness scripts/sympy_compute.py nullspace "[[1,2,3],[4,5,6]]"
Sympy_Rref
uv run python -m runtime.harness scripts/sympy_compute.py rref "[[1,2,3],[4,5,6]]"
Z3_Prove
uv run python -m runtime.harness scripts/z3_solve.py prove "subspace_closed"

Questions about vector-spaces.
- Which coding agents can use vector-spaces?
- vector-spaces installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
