scienceworld-tool-fetcher

This skill locates and picks up a specified tool or instrument from the environment. It should be triggered when a task requires a specific tool (e.g., thermometer, stopwatch) for measurement or manipulation. The skill identifies the tool's location via observation and executes a pick-up action, moving the tool to inventory.

Quality

Content

92%

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

The body is lean, actionable, and clearly sequenced with verification and recovery steps. Its main weakness is progressive disclosure: provided reference files are never signaled from the overview, and action detail that has a dedicated reference is inlined instead.

Suggestions

Add explicit links to the bundle files — e.g., point to references/environment_actions.md for the full action table, common tool locations, and error-handling notes — so the overview signals the deeper material.

Reconcile the inlined action guidance with environment_actions.md to avoid duplication: keep the SKILL.md overview lean and defer the detailed action table and tool-location lists to the reference.

Reconsider whether trajectory_analysis.md belongs in references/ — it is a design/derivation rationale rather than usage material; either move it out of the skill bundle or clearly label it as background so it does not read as a navigable reference.

DimensionReasoningScore

Conciseness

The ~30-line body is lean and assumes Claude's competence — it gives the goal, four short sequenced sections, and constraints with no padding or explanation of concepts Claude already knows, matching the score-3 'every token earns its place' anchor rather than the slightly-padded score-2 case.

3 / 3

Actionability

It provides concrete, executable game commands with placeholders and examples — `teleport to [ROOM_NAME]`, `look around`, `look at [CONTAINER]`, `pick up [TOOL_NAME]` (e.g., `pick up thermometer`) — which are copy-paste ready per the score-3 anchor rather than the pseudocode/incomplete score-2 case.

3 / 3

Workflow Clarity

A clear four-step sequence includes an explicit verification checkpoint ("Verify the action was successful by checking the observation for confirmation") and a tool-not-found recovery loop (teleport to other rooms and repeat the search); as a non-destructive single pick-up it is not subject to the validation cap, meeting the score-3 anchor.

3 / 3

Progressive Disclosure

The body is well-sectioned, but two bundle files exist in references/ (environment_actions.md, trajectory_analysis.md) and neither is linked or signaled from the body, while action-reference detail is inlined — matching the score-2 anchor 'references present but not clearly signaled; content that should be separate is inline' rather than the well-signaled one-level-deep references of score 3.

Description

100%

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, specific, third-person description that clearly states both capability and trigger conditions with concrete tool examples. It avoids fluff and over-claims while remaining tightly scoped to its niche.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — "locates and picks up a specified tool", "identifies the tool's location via observation", and "executes a pick-up action, moving the tool to inventory" — matching the score-3 anchor of multiple specific concrete actions rather than the partial coverage of score 2.

3 / 3

Completeness

It explicitly answers both what ("locates and picks up a specified tool…moving the tool to inventory") and when ("It should be triggered when a task requires a specific tool…for measurement or manipulation"), meeting the score-3 anchor for explicit what-and-when triggers.

3 / 3

Trigger Term Quality

It surfaces natural terms a user would say in this domain — "tool or instrument", "thermometer, stopwatch", "measurement or manipulation", and "pick-up" — giving good coverage rather than the sparse single-keyword case of score 2.

3 / 3

Distinctiveness Conflict Risk

The niche of fetching measurement instruments from the environment via observation is clearly bounded and unlikely to fire for unrelated skills, fitting the score-3 'clear niche with distinct triggers' anchor rather than the overlapping score-2 case.
