Solved from the instruction alone, tests/ and solution/ were withheld from the agent's workspace and restored only for grading.

Reward = tests/test.sh exit code (0 → resolved); the classification below is post-hoc and cannot change it.

Classification , post-hoc; cannot change the reward

HARNESS_ERRORInfrastructure failure, the agent never ran properly. Not a signal about agent or task.

SubtypeRate Limit / Session Timeout

Root causeThe Claude Code agent session hit a 429 rate limit immediately after receiving the task instruction, terminating before any work could be performed. This is an infrastructure/rate-limiting issue, not a task specification problem.

RecommendationN/A - task is fine. This is an agent rate-limiting infrastructure issue, not a task problem. The agent never executed, so task quality cannot be assessed from this trial.

# Track Particles Driven by Tile Type Gradient In `scenes/world.tscn`, add a TileSet custom data layer named `tile_type` with type int, and assign GradientTexture1D exports named `water_color`, `dirt_color`, and `grass_color` on the World node. In `scripts/world.gd`, add `enum TILE_TYPES { NONE, WATER, DIRT, GRASS }`, export the three GradientTexture1D variables (`water_color`, `dirt_color`, `grass_color`), create a dictionary mapping TILE_TYPES enum members to those gradients, and add a static `get_gradient_at(position)` that reads `get_custom_data_at(position, "tile_type")` and returns the matching gradient. In `scenes/tank.tscn`, add `LeftTrackParticles` and `RightTrackParticles` GPUParticles2D nodes configured to produce realistic track dust trails , use box emission, set directional flow in opposite vertical directions for left and right tracks, configure appropriate spread, disable gravity, set reasonable velocity and damping, use small particle scale, set amount and z_index appropriately, and start with emitting disabled. In `scripts/tank.gd`, track the current particle gradient using `World.get_gradient_at(position)`, assign it to each emitter's `process_material.color_ramp`, set both emitters to `emitting = true` while moving, and `emitting = false` when not moving, via a method named `_update_track_particles`.

Reproduce this trial: git checkout 327c807 && PYTHONPATH=src python3 scripts/build_site.py , then open trial/trial_3ef6a79cb44c477d. Re-running the agent live requires EVAL_PLATFORM_ENABLE_OAUTH_SMOKE=1 and is non-deterministic.
