alfworld-object-picker

Picks up a specified object from a given receptacle. Use this skill when the agent has located a required object and needs to acquire it for later use, such as taking an item from a surface or container. The skill requires the object and source receptacle as inputs, executing a 'take' action to transfer the object into the agent's inventory, enabling further manipulation like placement or usage.

Content

100%

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

The body is a model for a simple, single-action skill: concise, fully actionable, with a clear sequenced workflow and an error-recovery loop, plus appropriately separated troubleshooting detail. No significant weaknesses were found.

Dimension	Reasoning	Score
Conciseness	The body is lean (~20 lines) with no concept-explaining padding; every section (Inputs, Process, Output) earns its place and assumes Claude's competence.	3 / 3
Actionability	Provides the concrete executable command `take {object} from {source_receptacle}` plus specific input examples ("toiletpaper 1", "toilet 1"), making it copy-paste ready given the inputs.	3 / 3
Workflow Clarity	Three clearly sequenced steps (Verify Context, Execute Action, Handle Feedback) with an explicit error-recovery feedback loop that routes "Nothing happened" to troubleshooting.	3 / 3
Progressive Disclosure	Well-organized sections form a clear overview, and the one-level-deep `references/troubleshooting.md` reference is real and clearly signaled, keeping detail appropriately separated.	3 / 3
	Total	12 / 12 Passed

Description

75%

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

The description is well-structured with an explicit trigger and a clear, narrow niche, scoring high on completeness and distinctiveness. It is slightly held back by technical jargon in its trigger terms and by describing a single action rather than multiple.

Suggestions

Add user-natural phrasings alongside the technical terms, e.g. "grab" or "pick up an item from a surface or container" to broaden trigger coverage.

Consider framing the downstream capability ("enabling further manipulation like placement or usage") as a concrete second action to lift specificity toward the top anchor.

Dimension	Reasoning	Score
Specificity	Names the concrete action ("executing a 'take' action to transfer the object into the agent's inventory") but describes a single core action rather than the multiple specific actions the top anchor calls for.	2 / 3
Completeness	Clearly states what it does ("Picks up a specified object from a given receptacle") and gives an explicit "Use this skill when..." trigger clause, answering both what and when.	3 / 3
Trigger Term Quality	Includes natural terms like "pick up" and "take", but leans on technical jargon ("receptacle", "source receptacle") and is missing common variations a user might say.	2 / 3
Distinctiveness Conflict Risk	Targets a narrow ALFWorld niche (acquiring a located object from a receptacle) with a distinct trigger, making it unlikely to fire for navigation or placement skills.	3 / 3
