The validator is failing at:
> **Task Validation**
> **Not enough tasks with graders**
This means the system could not detect **at least 3 registered tasks that each have a grader**.
The hackathon explicitly requires:
> **minimum 3 tasks with agent graders**
> easy → medium → hard
> score in `[0,1]`
So your environment is likely exposing either:
* only **1 task**
* 3 tasks but **not registered**
* tasks exist but **grader missing / disabled**
* `openenv.yaml` only lists one task
This is now not an app error — it’s a **spec / task registration issue**.
---
# Most likely reason #1 (90% probability)
Your `openenv.yaml` probably has only one task.
Example of the problem:
```yaml
tasks:
- easy
```
This fails.
You need **3 tasks minimum**.
---
# Exact fix
Your `openenv.yaml` should look like this:
```yaml
name: trace
version: 1.0.0
description: AI-native incident response runtime
entrypoint: trace.env:TraceEnv
tasks:
- name: easy_incident
difficulty: easy
grader: trace.graders:grade_easy
- name: medium_cascade
difficulty: medium
grader: trace.graders:grade_medium
- name: hard_adversarial
difficulty: hard
grader: trace.graders:grade_hard
```
This is the most important fix.
---
# Most likely reason #2
You may have 3 scenarios in code, but only one is exposed to OpenEnv.
Example:
```python
TASKS = {
"easy": ...,
"medium": ...,
"hard": ...
}
```
This alone is not enough.
They must be **enumerable by the validator**.
Usually via `openenv.yaml` or task registry.
---
# Most likely reason #3
Graders missing.
The validator explicitly says:
> **tasks with graders**
That means each task needs a scoring function.
Example:
```python
def grade_easy(history):
return min(max(score, 0.0), 1.0)
def grade_medium(history):
return min(max(score, 0.0), 1.0)
def grade_hard(history):
return min(max(score, 0.0), 1.0)
```
Three separate graders is safest.
---
# What I strongly recommend
Make this exact structure.
---
## `tasks/`
```text
tasks/
├── easy_incident.yaml
├── medium_cascade.yaml
└── hard_adversarial.yaml
```
---
## `graders.py`
```python
def grade_easy(state):
...
def grade_medium(state):
...
def grade_hard(state):
...
```
---
## `openenv.yaml`
Explicitly map them.
This is what the validator likely parses.
---
# Quick emergency fix (best for resubmission)
Even if all 3 tasks use same environment class, expose them as separate tasks.
Example:
```yaml
tasks:
- name: easy
grader: trace.graders:grade_easy
- name: medium
grader: trace.graders:grade_medium
- name: hard
grader: trace.graders:grade_hard
```
This should pass validation.
---
# My blunt diagnosis
This is now **very close to passing**.
Your system is working.
The validator simply cannot “see” 3 tasks.
This is a **metadata + grader registration issue**, not a code failure.
Honestly, this is a good place to be.
If you want, paste your current `openenv.yaml`, and I’ll tell you exactly what needs to be changed to pass this check.
