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

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.

The body is a lean, actionable, well-sequenced instruction skill with a clear validation/feedback loop. Its one real gap is progressive disclosure: a bundle reference file exists but is not linked or signaled from the body.

Suggestions

Link references/action_primer.md from the body (e.g., under a 'References' section: 'For the full action list, see [action_primer.md](references/action_primer.md)') so the bundle is discoverable.

Cross-reference the open/toggle actions in step 3 to the action_primer so the reader knows where the exact action syntax lives.

Dimension	Reasoning	Score
Conciseness	Lean and efficient throughout — it states only what Claude needs (the procedure, key principles, one example) without explaining concepts Claude already knows or padding.	5 / 5
Actionability	Provides concrete executable actions — 'go to {target_receptacle}', 'open {recep}', 'toggle {obj} {recep}' — plus a fully worked trajectory example covering the common case.	5 / 5
Workflow Clarity	A clear 4-step sequence (Navigate → Observe → Analyze & Prepare → Confirm) with an explicit Confirm validation checkpoint and an abort/re-plan feedback loop for the invalid-target case.	5 / 5
Progressive Disclosure	Sections are well organized, but the bundle file references/action_primer.md is never linked or signaled from the body, so the reference is effectively buried despite being relevant to the documented actions.	3 / 5

Description

75%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.

The description is specific, concrete, and occupies a distinct niche with both 'what' and 'when' addressed. Its main weakness is the trigger phrasing, which uses a declarative 'It is triggered before...' rather than a natural 'Use when...' clause and lacks synonym coverage.

Suggestions

Replace 'It is triggered before placing an item into a receptacle' with an explicit 'Use when the goal requires placing an object in/on a receptacle (e.g., "put X in/on Y")' clause for natural trigger matching.

Add synonym coverage in the trigger clause (e.g., 'put in', 'place in', 'place on') to broaden natural-term matching.

Dimension	Reasoning	Score
Specificity	Names the domain and 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' — giving comprehensive coverage.	5 / 5
Completeness	Clearly answers 'what' (verifies and prepares a target receptacle) and 'when' (triggered before placing an item into a receptacle), but the 'when' is an implicit trigger statement rather than an explicit 'Use when...' clause, keeping it just below a 5.	4 / 5
Trigger Term Quality	The trigger phrase 'It is triggered before placing an item into a receptacle (e.g., a garbage can)' is relevant but phrased in third-person declarative rather than natural 'Use when...' user phrasing, and lacks synonym coverage.	3 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (receptacle preparation before object placement) with a distinct trigger and minimal overlap risk with other skills.	5 / 5
