alfworld-receptacle-preparer

This skill verifies and prepares a target receptacle for receiving an object. It is triggered before placing an item into a receptacle (e.g., a garbage can) to ensure the receptacle is accessible and suitable. The skill involves navigating to the receptacle, observing its state (e.g., open/closed, occupied), and performing any necessary preparatory actions like opening it, resulting in a ready-to-use target location.

Content

92%

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

The content is concise, highly actionable, and has a well-sequenced workflow with validation and recovery steps. The only gap is that the existing action_primer.md reference is never linked from the body, weakening progressive disclosure.

Suggestions

Add an explicit pointer to the bundle, e.g. under Core Procedure or a References section: 'See references/action_primer.md for the full action list and placeholder conventions,' so the one-level-deep reference is clearly signaled.

Optionally move the per-action placeholder details (e.g. {obj}/{recep} replacement rules) to the reference rather than duplicating them inline.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes Claude's competence — it skips explaining what ALFWorld or receptacles are, and every section (Core Procedure, Key Principles, Example) earns its place without padding.	3 / 3
Actionability	It provides concrete, executable commands with exact placeholders (`go to {target_receptacle}`, `open {recep}`, `toggle {obj} {recep}`) plus a fully worked trajectory example, matching the 'fully executable; copy-paste ready' anchor.	3 / 3
Workflow Clarity	The Core Procedure is a clearly numbered sequence with an explicit 'Confirm' validation checkpoint and an error-recovery branch ('Nothing happened' → abort and re-plan), satisfying the anchor for a clear sequence with explicit validation and feedback loops.	3 / 3
Progressive Disclosure	A bundle reference file (references/action_primer.md) exists, but the body never signals or links to it — there is no 'See action_primer.md' pointer — so the reference is present yet not clearly signaled from the overview.	2 / 3

Description

85%

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 specific, complete, and well-differentiated, clearly stating both the capability and its trigger. Its main weakness is trigger term breadth, relying on somewhat formal phrasing rather than the fuller range of natural terms a user might use.

Suggestions

Broaden trigger terms to cover natural variations users might say, e.g. adding 'open, close, check, or prepare a container/receptacle before putting something in it' alongside the existing "put X in/on Y" phrasing.

Consider adding an explicit 'Use when...' clause to make the trigger guidance more conventional and machine-recognizable.

Dimension	Reasoning	Score
Specificity	The description lists multiple concrete actions: "navigating to the receptacle, observing its state (e.g., open/closed, occupied), and performing any necessary preparatory actions like opening it," matching the anchor for listing several specific actions.	3 / 3
Completeness	It explicitly answers both what ("verifies and prepares a target receptacle") and when ("It is triggered before placing an item into a receptacle"), and the explicit trigger guidance present here lifts it above the cap that applies only when such guidance is missing.	3 / 3
Trigger Term Quality	It includes relevant trigger phrasing like "put X in/on Y" and "placing an item into a receptacle," but the surrounding vocabulary ("receptacle," "receiving an object") is somewhat formal and misses several natural variations a user might say, fitting the 'some relevant keywords but missing common variations' anchor.	2 / 3
Distinctiveness Conflict Risk	It carves a clear niche (preparing a receptacle before placing into it) with distinct triggers, and even distinguishes it from a separate search task, making overlap with other skills unlikely.	3 / 3
