Route Z80

Select the domain by requested outcome. $workflow separately owns execution effort; do not load its routes during domain selection.

Selection

1. Honor an explicitly named skill unless it conflicts with the requested outcome; explain a material conflict instead of silently substituting.
2. Identify the requested deliverable, not repository keywords or incidental implementation steps.
3. Select one primary route from the table and load only that sibling skill.
4. Use a second specialist only for a separate explicit objective or when the primary specialist uncovers a material blocker owned by that domain.

Select an unambiguous match immediately. If size, structure, and performance appear together as alternatives without a primary outcome, remain in route-z80 and ask one focused question. Alternatives are not competing acceptance criteria.

Requested outcome / boundary	Route
Send named files/directories through BridgeZX, including build artifacts. Building or changing them is a separate objective.	send-bridgezx
Start, resume, implement, diagnose, validate, or hand off an existing program's Spectranext cartridge consumer port through its external pipeline.	port-spectranext
Explicit product initiative needing specification and milestones, or an active develop dossier. A routine feature, plan, or implementation alone does not qualify.	develop-z80
Create, restructure, review, or synchronize public repository documentation, including one README.	document-z80
Diagnose, or diagnose and repair, one observed failure with unresolved causality, conflicting evidence, or a failed evidence-supported fix. Includes regression against a known baseline.	debug-z80
Preventive or broad read-only correctness audit, or the correctness risk of a change set (diff, branch, PR): ABI, ISR, memory, firmware, toolchain, or hardware risks, without one failure driving the investigation.	audit-z80
Map or reorganize ownership, dependencies, modules, source layout, banks, overlays, or runtime placement.	organize-z80
Size or memory footprint is the sole acceptance metric; prove net byte savings.	shrink-z80
Improve acceptable behavior: identify bottlenecks and rank speed, size, RAM, rendering, latency, or competing metrics.	optimize-z80
An ordinary bounded fix whose cause is already established, implementation, review, refactor, test, build, source comment, agent instructions, or non-repository prose without a specialist evidence question.	workflow

Spectranext is not shorthand for the ZX Spectrum Next platform. Generic Next products follow the product/workflow rows; changes to the cartridge pipeline itself follow their engineering outcome, not the consumer-port route. Unresolved Z80 failures use debug-z80 rather than a generic debugging workflow.

Handoff

State the selected route in one sentence and continue with it. Do not request confirmation for an unambiguous selection, summarize unused skills, or load every sibling SKILL.md.
