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.

Content

82%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 tight, well-structured instruction body that pairs an explicit step sequence with a properly scoped reference file. The main gaps are minor: the in/on selection rule is delegated rather than stated inline, and the error-recovery loop points outward instead of giving a concrete fix-retry cycle.

Suggestions

Inline a one-line preposition selection rule (or a compact receptacle-type table) so the core workflow is fully executable without consulting the reference.

Expand the error-handling step into an explicit validate-fix-retry loop (e.g., on "Nothing happened" -> open receptacle / swap preposition / verify holding -> retry) before deferring to the reference.

Add a short dedicated 'References' section signaling action_guide.md so navigation is visible at a glance rather than buried in step 4.

Dimension	Reasoning	Score
Conciseness	The body is lean and entirely action-oriented with no padding or explanation of concepts Claude already knows; every line (prerequisite checks, `go to {recep}`, `put {obj} in/on {recep}`, error pointer) earns its place.	5 / 5
Actionability	Provides concrete, executable AlfWorld commands (`go to {recep}`, `put {obj} in/on {recep}`) and a real reference file, but defers the in/on preposition selection to "the trajectory as a reference" rather than specifying it inline, leaving a minor gap versus fully copy-paste-ready guidance.	4 / 5
Workflow Clarity	A clear four-step sequence (verify prerequisites, navigate, execute, handle errors) with an explicit prerequisite check and an error-recovery pointer, but the error step says "consult the reference" rather than spelling out a concrete validate-fix-retry loop, keeping it just below anchor 5.	4 / 5
Progressive Disclosure	The body is well-organized into numbered sections and pushes troubleshooting detail to a single, real, one-level-deep reference (`references/action_guide.md`, verified to exist) that is clearly signaled in the error-handling step; it falls short of anchor 5 only because navigation to the reference is embedded in an error line rather than a dedicated overview section.	4 / 5

Description

82%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, concise description that clearly communicates both capability and trigger conditions for a narrow task niche. Its only weakness is specificity: it elaborates one action with synonyms rather than enumerating multiple distinct capabilities.

Suggestions

Replace synonymic verbs (deposit/installing/storing) with genuinely distinct concrete actions or supported input variations to lift specificity toward anchor 4-5.

Consider naming the AlfWorld environment or receptacle vocabulary explicitly to further sharpen distinctiveness and trigger terms.

Dimension	Reasoning	Score
Specificity	Names the domain and the concrete core action ("performing a 'put' action", "Places a held object onto or into a target receptacle"), but the additional verbs (deposit, installing, storing) are paraphrases of the same single action rather than several distinct capabilities, so it does not reach the multi-action coverage of anchor 4.	3 / 5
Completeness	Explicitly states both what it does (places a held object onto/into a receptacle via a 'put' action) and when to use it ("Trigger this skill when the agent is carrying an object and needs to deposit it at a specific location to complete a task"), matching the anchor-5 example of clear what-and-when with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural trigger phrasing ("Trigger this skill when the agent is carrying an object and needs to deposit it", "installing an item on a holder", "storing it in a container") with good keyword coverage, falling just short of the comprehensive synonym/extension coverage of anchor 5.	4 / 5
Distinctiveness Conflict Risk	Targets a narrow AlfWorld niche (placing a currently-held object into a receptacle via 'put') with distinct triggers, leaving minimal overlap risk with other skills.	5 / 5
