C++ Engine Core

Use this skill to implement robust C++ engine core changes with strict correctness gates.

Workflow

1. •Define scope and constraints.

• •Define subsystem scope, invariants, and API boundaries.
• •Capture objective metrics, bounds, and release blockers.

1. •Design implementation plan.

• •Design module-level changes with safety/performance implications.
• •Keep ownership and dependency boundaries explicit.

1. •Execute and iterate.

• •Implement in small, traceable increments.
• •Record run/build context for reproducibility.

1. •Validate contract integrity.

• •Validate invariants, failure behavior, and benchmark regression gates.
• •Treat contract breaches as blockers.

1. •Prepare handoff.

• •Deliver patch map, risk notes, and verification commands.
• •Include exact commands and acceptance criteria.

Output Contract

Return:

1. •Context: goals, assumptions, constraints.
2. •Validation: pass/fail checks and key deltas.
3. •Changes: concrete file-level updates.
4. •Commands: commands and expected outputs.
5. •Risks: unresolved issues and limits.

Execution Rules

• •Keep decisions measurable and reversible.
• •Keep validation criteria explicit before iteration.
• •Escalate invariant breaks and regression-risky changes as blockers.
