| description | Discovers and invokes Nexa skills. Use when starting a session or to identify which skill is appropriate for the task at hand. This is the orchestrator skill which governs how all Nexa skills are discovered and invoked. |
Nexa Skills is a set of engineering workflow skills which are intended to be used in the various phases of software development. This skill in particular helps you discover and apply the appropriate skill for the task at hand.
When a task arrives, identify the development phase and apply the corresponding skill:

These behaviors apply at all times, across all skills. They are non-negotiable.
Before implementing anything non-trivial, explicitly state your assumptions:
ASSUMPTIONS I'M MAKING:
1. [assumption about requirements]
2. [assumption about architecture]
3. [assumption about scope]
→ Correct me now or I'll proceed with these.
Don't silently fill in ambiguous requirements. The most common failure mode is making wrong assumptions and running with them unchecked. Surface uncertainty early — it's cheaper than rework.
When you encounter inconsistencies, conflicting requirements, or unclear specifications:
Bad: Silently picking one interpretation and hoping it's right. Good: "I see X in the spec but Y in the existing code. Which takes precedence?"
You are not a yes-machine. When an approach has clear problems:
Sycophancy is a failure mode. "Of course!" followed by implementing a bad idea helps no one. Honest technical disagreement is more valuable than false agreement.
Your natural tendency is to overcomplicate. Actively resist it.
Before finishing any implementation, ask:
If you build 1000 lines and 100 would suffice, you have failed. Prefer the boring, obvious solution. Cleverness is expensive.
Touch only what you're asked to touch.
Do NOT:
Your job is surgical precision, not unsolicited renovation.
Every skill includes a verification step. A task is not complete until verification passes. "Seems right" is never enough — there must be evidence (passing tests, build output, runtime data).
These are the subtle errors that look like productivity but create problems:
Check for an applicable skill before starting work. Skills encode processes that prevent common mistakes.
Skills are workflows, not suggestions. Follow the steps in order. Don't skip verification steps.
Multiple skills can apply. A feature implementation might involve design-screens → deliver-use-case in sequence.

| Construction | /sprint-deliver | Deliver use cases in priority order from readiness report |
| Completion | /sprint-complete | Close sprint: validate, close GH issues, dashboard, archive, publish |
Orchestrates the full bugfix pipeline for a BUG-XXX or GitHub issue: an isolated tester reproduces the bug and updates the issue, a senior-dev agent writes a root-cause fix plan while a business-analyst agent links the affected requirement(s) in parallel, then the fix is implemented and gated on Definition of Done. Use when the user asks to "fix this bug", "resolve BUG-XXX", "run the bugfix pipeline", pastes a GitHub issue link and asks to fix it, or mentions an end-to-end bug resolution workflow.
Creates structured change request documents for intentional modifications to already-implemented use cases. Use when the user asks to "create a change request", "log a CR", "document a change", or describes a stakeholder-requested modification to existing behavior (e.g., renaming a field, changing validation rules, restructuring data). A change request always references exactly one use case and describes only the delta — the original use case remains immutable.
Creates structured bug report documents with reproduction steps, expected vs actual behavior, and severity classification. Use when the user asks to "report a bug", "file a bug", "document a defect", "log an issue", or mentions a bug, defect, regression, or unexpected behavior that needs to be tracked.
Runs a comprehensive implementation audit for a delivered use case. Checks Definition of Done, i18n completeness and correctness, error message i18n, accessibility, visual fidelity against the design, and loading/error states. Run after /deliver-use-case or before /sprint-complete for a quality deep-dive. Results are advisory — Critical and Major findings should be fixed; Minor findings are observations.
Lead Requirements Engineer that systematically elaborates all use cases through structured analysis, probing questions, and iterative refinement. Processes use cases in thematic clusters, applies CRUD matrix analysis, actor-goal completeness, exception path probing, MoSCoW prioritization, and traceability checks. Spawns a Product Owner sub-agent to answer clarification questions — only genuinely ambiguous decisions reach the human. Updates requirements, entity model, and use case diagram as living documents. Use when the user asks to "engineer requirements", "elaborate use cases", "analyze use cases", "validate use case completeness", "deep-dive on requirements", "prioritize requirements", or mentions requirements engineering, use case elaboration, MoSCoW, or completeness analysis.
Selects a subset of use cases for a sprint, refines requirements, evolves the entity model and use case diagram, generates specs and designs, and produces a sprint readiness report. Treats requirements, entity model, and use case diagram as living documents that evolve per sprint while protecting delivered use cases as immutable. Use when the user asks to "prepare a sprint", "scope a sprint", "refine for sprint", "get use cases ready for delivery", "sprint planning", or mentions sprint preparation, sprint scoping, or delivery readiness.
