ALWAYS use when compiling DXIL/HLSL to metallib with Metal shader converter (commonly referred to as MSC) via the metal-shaderconverter CLI or libmetalirconverter (IRCompiler, IRObject, IRShaderReflection) at runtime. Covers offline/runtime DXIL compilation, root signatures, reflection output, ray tracing shaders, geometry/tessellation emulation compilation, framebuffer fetch in HLSL, programmable blending in HLSL, Metal_HLSL.inc, and compatibility flags. Do NOT trigger for binding compiled shaders to encoders — use integrating-metal-shaderconverter-shaders for that.
ALWAYS use when creating Metal pipeline state objects with Metal 4 descriptors (MTL4RenderPipelineDescriptor, MTL4ComputePipelineDescriptor, MTL4MeshRenderPipelineDescriptor) via MTL4Compiler. Covers function descriptors, function constant specialization, flexible/unspecialized PSOs, color-attachment mapping, async compilation (MTL4CompilerTask), pipeline caching (MTL4Archive, MTL4PipelineDataSetSerializer), static/binary shader linking, and pipeline reflection. Do NOT trigger for HLSL/DXIL → metallib — use compiling-with-metal-shaderconverter.
ALWAYS use when a user porting a game to Metal reports a rendering issue — blank screen, wrong output, or anything that looks incorrect on Metal vs. the source platform. Covers black screen, missing geometry, wrong colors, gamma/sRGB problems, texture artifacts, z-fighting, alpha blending, flickering, visual corruption, and upside-down/mirrored geometry. Works with or without a GPU trace. Do NOT trigger when the user just wants to inspect an existing .gputrace.
ALWAYS use when integrating Metal shader converter (commonly referred to as MSC) shaders at runtime — binding model, top-level argument buffer (TLAB), root signature resource locations, descriptor/sampler heaps, static samplers, bindless resources, vertex fetch, separate stage-in, geometry/tessellation emulation, compute dispatch, unbounded arrays, and append/consume buffers. Do NOT trigger for compiling DXIL/HLSL to metallib — use compiling-with-metal-shaderconverter for that.
ALWAYS use when writing or porting Metal object lifetime management code in metal-cpp — including crashes on release, use-after-free, memory leaks, autorelease pool placement, NS::TransferPtr vs NS::RetainPtr ownership, bridge casts at ARC/metal-cpp boundaries, or any question about when and how Metal objects are retained, released, or destroyed.
ALWAYS use when working with Metal 4 resources — buffer / texture / heap creation, storage modes, `MTLResidencySet` management, heap aliasing, purgeable state, texture view pools, GPU lossless compression, and deferred destruction. Trigger for MTLBuffer, MTLTexture, MTLHeap, MTLResidencySet, addAllocation, requestResidency, useResidencySet, addResidencySet, MTLStorageMode*, MTLPurgeableState, MTLTextureViewPool, MTLResourceViewPool, newTextureViewWithPixelFormat:, copyFromBuffer:toTexture:, "GPU fault on resource", "non-resident resource", heap aliasing. Do NOT trigger for TBDR architecture or Metal 3 → Metal 4 namespace tables — use `translating-to-metal4-api`. Barrier visibility / `MTL4VisibilityOption*` / render-pass transition barriers — use `managing-metal4-synchronization`. `CAMetalLayer.residencySet` — use `presenting-metal-drawables`. `NS::SharedPtr` / autorelease pool / ARC bridging — use `managing-metal-cpp-lifetimes`.

You are entering Phase 4: Handoff for the current milestone.
Locate the agent's artifact directory at <project-root>/.porting/ (defined in porting-methodology). All artifacts live there. Load the porting-methodology skill if not already in context.
Ask the user to commit any uncommitted work before proceeding:
"Before writing the handoff, please commit any uncommitted changes."
Wait for the user to confirm the commit is done.
Read porting-memory.md from the artifact directory and update it:
Determine the current goal name from the goal document (goal-<name>.md). Write a handoff note to the artifact directory as porting-handoff-<goal-name>-M<x>.md (e.g., handoff-basic-rendering-M2.md):
# Handoff: [Milestone Name]
## What Was Done
[One-paragraph summary of the milestone — what was implemented, what's now working]
## Ground Truth Comparison
[Full report of ground truth reference checks performed during validation. For each artifact compared:]
- [Which reference artifact was used (translation-layer capture, RenderDoc XML, etc.)]
- [What was compared (pass structure, draw counts, output textures, resource bindings)]
- [What matched and what diverged]
- [Whether divergences are expected (features not yet implemented) or need investigation]
- [If no ground truths were compared, state why (non-rendering milestone, artifacts unavailable)]
## What's Deferred
[Specific TODOs and STUBs created, with grep patterns]
- `grep "STUB(M<next>)"` — [description of what these stubs are]
## Known Issues
[Bugs, artifacts, validation warnings not yet fixed]
## Watch For
[Things that will trip you up next milestone — specific, actionable warnings]
## Key Decisions Made
[Why something was done a certain way, so the next session doesn't undo it]
## Skills Needed Next
[Which skills the agent should load for the next milestone]
Read the goal document (goal-*.md in the artifact directory) and update the current milestone's status to "Complete".
Present a summary of all artifacts created or updated:
## Handoff Summary
### Artifacts Updated
- porting-memory.md — [what changed: watch list items added/removed, feature status updates, knowledge added]
- Handoff note — written to <project-root>/.porting/porting-handoff-<goal-name>-M<x>.md
- Goal document — milestone [name] marked Complete
### Next Milestone
[Name and success criterion of the next milestone, or "All milestones complete — run /porting-plan-goal"]
### Watch List (current state)
[Show the current watch list from porting-memory.md so the user can review]
After the user has reviewed the handoff summary:
"Milestone complete. Please start a new session for the next milestone."
Do NOT continue working on the next milestone in this session. The one-session-per-milestone model keeps each milestone's changes bounded and reviewable.
