alfworld-object-placer

Places a held object onto or into a target receptacle. Trigger this skill when the agent is carrying an object and needs to deposit it at a specific location to complete a task, such as installing an item on a holder or storing it in a container. It takes the object and destination receptacle as inputs, performing a 'put' action to finalize the object's positioning according to the task goal.

Quality

Content

100%

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

An excellent, concise instruction body: concrete actions, an explicit prerequisite-validation step, an error-handling step, and proper one-level-deep delegation to a real reference file. No wasted tokens.

Dimension	Reasoning	Score
Conciseness	The body is lean (~20 lines), assumes Claude's competence, explains no background concepts, and every line contributes actionable guidance.	3 / 3
Actionability	Provides concrete executable AlfWorld action strings (`go to {recep}`, `put {obj} in/on {recep}`) plus an inline in/on rule keyed to receptacle type, with the detailed preposition table and failure modes delegated to the reference.	3 / 3
Workflow Clarity	A clear four-step sequence (verify prerequisites, navigate, execute, handle errors) with an explicit validation checkpoint in step 1 and a defined error signal ('Nothing happened') plus recovery path in step 4.	3 / 3
Progressive Disclosure	The body is a concise overview that delegates troubleshooting to references/action_guide.md, a one-level-deep, clearly signaled reference that exists in the bundle.	3 / 3
	Total	12 / 12 Passed

Description

90%

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 well-written description in third person with an explicit trigger clause, concrete action, and clear niche. The only weakness is that it describes one action with variants rather than multiple distinct capabilities, capping specificity at 2.

Dimension	Reasoning	Score
Specificity	Names the concrete 'put' action and placement variants (install on a holder, store in a container), but describes a single core action rather than multiple distinct capabilities, matching the 'names domain and some actions' anchor rather than 'lists multiple specific concrete actions'.	2 / 3
Completeness	Explicitly answers both 'what' (places a held object onto/into a receptacle via a 'put' action) and 'when' via a clear 'Trigger this skill when...' clause.	3 / 3
Trigger Term Quality	Phrases like 'carrying an object', 'deposit', 'installing an item on a holder', and 'storing it in a container' give good coverage of natural terms an agent would use when this skill is needed.	3 / 3
Distinctiveness Conflict Risk	The narrow niche of depositing a currently-held object into a specific receptacle, with distinct carrying/deposit triggers, makes it unlikely to fire for unrelated skills.	3 / 3
	Total	11 / 12 Passed
