alfworld-object-state-inspector

Inspects a receptacle's contents by navigating to it and reading the observation. Use when you need to check what is on or inside a receptacle (e.g., "what's on the shelf", "is the holder empty", "check the table for items"). Executes `go to {receptacle}`, parses the observation listing items present, and decides whether to take an item, search elsewhere, or proceed.

Quality

Content

88%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A concise, actionable, single-purpose skill body with a clear workflow and concrete examples. The main gap is the orphaned, unreferenced (and truncated) reference file that should either be linked or removed.

Suggestions

Either link references/alfworld_actions_ref.md from the body (e.g., 'See references/alfworld_actions_ref.md for full observation patterns') or remove it if unused.

Complete the truncated 'Skill Integration in Task Flow' section in the reference file, which currently ends mid-sentence.

Tighten the 'Read observation' step wording to remove the restated clarification about no additional action being needed.

Dimension	Reasoning	Score
Conciseness	The body is lean and avoids explaining concepts Claude already knows, but a few workflow lines (e.g., restating that no extra inspection action is needed) could be tightened further.	4 / 5
Actionability	Provides fully executable commands (`go to {target_receptacle}`, `take {item} from {receptacle}`) plus two complete action/observation/decision examples that are copy-paste ready.	5 / 5
Workflow Clarity	Clear Navigate → Read → Parse → Decide sequence with an Error Recovery section; as a read-only single-purpose skill it needs no destructive-operation validation, satisfying the simple-skill exception.	5 / 5
Progressive Disclosure	Well-organized into Workflow, Error Recovery, and Example sections under 50 lines, but a bundle file (references/alfworld_actions_ref.md) exists without being linked or signaled from the body.	4 / 5

Description

88%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that clearly communicates capability and trigger conditions in third-person voice with concrete natural-language examples. Minor improvements possible around additional trigger synonyms and explicit environment scoping.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'navigating to it and reading the observation', 'Executes `go to {receptacle}`', 'parses the observation', 'decides whether to take an item, search elsewhere, or proceed' — giving comprehensive coverage of what the skill does.	5 / 5
Completeness	Explicitly states both the 'what' (inspects contents via navigation and observation parsing) and the 'when' ('Use when you need to check what is on or inside a receptacle') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural user phrases like 'what's on the shelf', 'is the holder empty', and 'check the table for items', but is missing a few common variations such as 'look in' or 'examine'.	4 / 5
Distinctiveness Conflict Risk	The receptacle-inspection niche with specific triggers is mostly distinct, but the absence of an explicit AlfWorld framing leaves minor overlap risk with generic container-search skills.	4 / 5
	Total	18 / 20 Passed
