name: assembly-program description: Execute 6502/6510 assembly workflows through c64bridge.

Intent

Use this skill for custom assembly routines, register work, IRQ handlers, and hardware-timed code.

Inputs

• Hardware focus: VIC-II, SID, CIA, or mixed.
• Memory layout constraints, zero-page usage, and interrupt ownership.
• Validation target: screen state, memory state, or register state.

Execution

1. Clarify which hardware blocks and memory ranges the routine may touch.
2. Consult c64://assembly/6510-spec, c64://memory/map, and any hardware-specific resource that applies.
3. Use c64_rag with op: "asm" when targeted timing tables or code examples are needed.
4. Generate assembly source with explicit labels and memory usage.
5. Execute with c64_program using op: "upload_run_asm".

Validation

1. Use c64_memory with op: "read" for installed code, vectors, or register checks.
2. Use c64_memory with op: "read_screen" when the routine produces visible output.
3. Report assembler diagnostics directly if compilation fails.

Safety

• Confirm before invasive recovery actions such as reset or reboot.
• Pause and resume the machine around manual memory patching when the workflow requires it.

Escalation

• Switch to .github/skills/basic-program/SKILL.md when the task is better served by a high-level loader or a simple BASIC program.
