# Programming Fullstack Product Engineering Skill 2026 Skill

## Mission
Aplica ingenieria de software moderna para fullstack product engineering con foco en robustez, mantenibilidad y excelencia operacional.

## When to use
- When the user asks for a repeatable workflow in this domain.
- When a specialized checklist improves speed or quality.

## Inputs expected
- Task objective and expected output.
- Relevant files, paths, or system constraints.
- Any non-negotiable requirements (security, style, deadlines).

## Workflow
1. Understand scope, assumptions, and risks.
2. Execute the workflow in a deterministic order.
3. Verify outcomes and report any limitations clearly.

## Output contract
Provide results in this order: key outcome, concrete changes, validation status, next steps.

## Guardrails
- Never fabricate facts, outputs, or tool results.
- Ask for confirmation before destructive operations.
- Prefer minimal, reversible changes when uncertain.

## Foundations
- `algorithm-correctness-invariants`
- `complexity-analysis-foundations`
- `type-systems-foundations`
- `debugging-causal-reasoning-foundations`
- `testing-verification-foundations`
- `security-threat-modeling-foundations`


## Logical reliability checklist
- Assumptions are explicit and separated from verified facts.
- The solution path is justified with clear reasoning steps.
- Edge cases and contradiction checks are included.
- Output is testable, auditable, and reversible when possible.

## Example prompts
- "Apply the programming-fullstack-product-engineering-skill-2026 skill to handle this task end-to-end."
- "Run programming-fullstack-product-engineering-skill-2026 and produce a production-ready output with validation notes."
