Use when working on 3D-specific rendering — deferred chain, G-buffer, clustered shading, Stratum GI, ReGIR, SVGF/A-SVGF, TAA, shadow techniques, depth/HZB, anything 3D-specific. ALWAYS load titan-rendering-core first; this skill assumes core conventions. Loads Titan-specific overrides for realtime-rendering. NOT for 2D rendering or editor panels.
Use when diagnosing a Titan renderer artifact — flicker, ghosting, fireflies, banding, light leaks, seams, boil, NaN/Inf, aliasing, smear/trails, dark voids, shadow artifacts, GI instability, denoiser/TAA issues. The frame-isolation-first debugging method: capture 60Hz, diff frames / A-B vs classical, consult literature, isolate via systematic-debugging, propose (and prove) a fix, record empirically. NOT for landing the production fix (hand to titan-rendering-3d-agent), 2D rendering, or editor panels.
Use when working in titan-rendering-frame-graph, titan-rendering-core, or titan-rendering-post-process-core — frame graph DAG, RenderTarget, DevicePool, PostProcessHook, CameraFrameData, HDR intermediate, tonemap, color management. Foundational layer shared between current 3D and future 2D rendering. Loads Titan-specific overrides for realtime-rendering. NOT for 3D-specific concerns (deferred chain, GI, shadows) — load titan-rendering-3d after this.
When a Titan bench tool using Renderer3d lacks on_resize → renderer.resize(), depth_prepass_view and HZB occlusion resources are never created — DepthPrepass, HzbBuild, and SceneCull passes silently skip, and taps produce no output
When adding a camera UBO shared between Rust and WGSL, verify field-by-field that the CPU layout matches the WGSL struct — especially packed vec4 fields where reordering silently breaks the shader
When building a depth prepass for reverse-Z HZB occlusion culling, use Greater compare (not Always) — the closest fragment must win so the HZB stores the nearest occluding surface, not the farthest

QWEN.md requires that the LAST step of every plan, phase, and handoff updates the appropriate docs and skills with empirically verified findings. A plan is NOT complete until docs reflect what was learned.
When this rule is repeatedly violated, the fix is a PreToolUse hook on
git commit — same pattern as todo_gate_guard.py and
rendering_naming_guard.py.
Write a Python script in .qwen/local-scripts/:
Bash tool call containing git commitgit diff --staged --numstat and --name-only| Domain | Code patterns (prefix match) | Doc patterns (prefix match) |
|---|---|---|
| rendering | crates/titan-rendering, crates/titan-stratum-lighting | docs/rendering/, docs/design/, docs/agent-kb/, .qwen/skills/titan-rendering |
| editor | crates/titan-editor/ | docs/editor/, .qwen/skills/titan-editor/ |
| streaming | crates/titan-world | docs/editor/, .qwen/skills/titan-world-streaming/ |
Global doc files (count for all domains): docs/PLAN.md, docs/TODO.md,
docs/OPEN_BUGS.md, docs/POST_WORK_FINDINGS.md.
Use module-level _staged_files_fn and _staged_diff_stat_fn variables
that default to None — the real functions are called only when these are
None. Tests set them to lambda overrides. This avoids fragile monkey-patching
of module namespace entries.
When QWEN.md documentation-co-update rules have no mechanical enforcement and the user reports repeated violations. Write the hook, add tests, commit.
C:\Dev\Titan\.qwen\local-scripts\doc_gate_guard.py — 8 tests,
test_doc_gate_guard.py.
All four mechanical gates follow the same .qwen/local-scripts/*.py pattern,
auto-discovered by Qwen Code:
| Hook | Trigger | Rule |
|---|---|---|
rendering_naming_guard.py | Write/Edit | No proprietary names in code |
todo_gate_guard.py | Write/Edit | // TODO: must be in docs/TODO.md |
scope_guard.py | Write/Edit | No writes outside .qwen/task_scope.json |
doc_gate_guard.py | git commit | >50 lines code must co-update docs |
evaluate() / main() never raise; any error → allow.rs/.wgsl for code-level hooks;
