Math Review

name: math-review description: |

Triggers: verification, algorithms, scientific, stability, math Intensive mathematical analysis for numerical stability, algorithm correctness, and alignment with authoritative standards.

Triggers: math review, numerical stability, algorithm correctness, mathematical verification, scientific computing, numerical analysis, derivation check

Use when: reviewing math-heavy code, verifying algorithm correctness, checking numerical stability, aligning with mathematical standards

DO NOT use when: general algorithm review - use architecture-review. DO NOT use when: performance optimization - use parseltongue:python-performance.

Use this skill for mathematical code verification. category: specialized tags: [math, algorithms, numerical, stability, verification, scientific] tools: [derivation-checker, stability-analyzer, reference-finder] usage_patterns: - algorithm-review - numerical-analysis - derivation-verification - stability-assessment complexity: advanced estimated_tokens: 200 progressive_loading: true dependencies: - pensive:shared - imbue:evidence-logging version: 1.3.7

Mathematical Algorithm Review

Intensive analysis ensuring numerical stability and alignment with standards.

Quick Start

/math-review

Verification: Run the command with --help flag to verify availability.

When to Use

• Changes to mathematical models or algorithms
• Statistical routines or probabilistic logic
• Numerical integration or optimization
• Scientific computing code
• ML/AI model implementations
• Safety-critical calculations

Required TodoWrite Items

1. math-review:context-synced
2. math-review:requirements-mapped
3. math-review:derivations-verified
4. math-review:stability-assessed
5. math-review:evidence-logged

Core Workflow

1. Context Sync

pwd && git status -sb && git diff --stat origin/main..HEAD

Verification: Run git status to confirm working tree state. Enumerate math-heavy files (source, tests, docs, notebooks). Classify risk: safety-critical, financial, ML fairness.

2. Requirements Mapping

Translate requirements → mathematical invariants. Document pre/post conditions, conservation laws, bounds. Load: modules/requirements-mapping.md

3. Derivation Verification

Re-derive formulas using CAS. Challenge approximations. Cite authoritative standards (NASA-STD-7009, ASME VVUQ). Load: modules/derivation-verification.md

4. Stability Assessment

Evaluate conditioning, precision, scaling, randomness. Compare complexity. Quantify uncertainty. Load: modules/numerical-stability.md

5. Evidence Logging

pytest tests/math/ --benchmark
jupyter nbconvert --execute derivation.ipynb

Verification: Run pytest -v tests/math/ to verify. Log deviations, recommend: Approve / Approve with actions / Block. Load: modules/testing-strategies.md

Troubleshooting

Common Issues

Command not found Ensure all dependencies are installed and in PATH

Permission errors Check file permissions and run with appropriate privileges

Unexpected behavior Enable verbose logging with --verbose flag
