Use when the agent needs to check whether an ALFWorld task objective has been met after completing a sub-action (e.g., placing an object). This skill parses the task goal, evaluates the latest environment observation, and outputs a verification decision — task complete, task incomplete, or action ineffective — to guide the next step.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill: Task Verifier for ALFWorld
## When to Use
Trigger this skill when:
1. The agent has just completed a key sub-action (e.g., `put {obj} in/on {recep}`)
2. The agent needs to determine whether the overall task goal is satisfied
3. The agent must decide whether to continue searching or conclude the task
## Core Workflow
### 1. Parse the Task Goal
Extract from the original task description:
- **Target object(s)**: What needs to be found/placed (including quantity)
- **Target receptacle**: Where objects must end up
- **Required transformations**: Any cleaning, heating, or cooling steps
### 2. Analyze the Observation
Evaluate the most recent `Observation:` text from the environment:
- Look for evidence that required objects are present in the target receptacle
- Count how many target objects have been successfully placed
- Note: Other items in the receptacle do not invalidate success
### 3. Make a Verification Decision
| Condition | Decision | Output |
|-----------|----------|--------|
| All required objects confirmed in target receptacle | Complete | `Verification: Task complete. No further action needed.` |

How to install
mdr add zjunlp/skillnet/alfworld-task-verifier@sha256:c6627bfb85b70b8cThe line at the top of this page pins the label git:20260316.e08426e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
