scienceworld-living-entity-identifier

Analyzes room observations to identify potential living things (e.g., eggs, plants, animals) among listed objects. Use this skill when a task involves finding, focusing on, or interacting with a living thing, biological entity, or organism. Processes observation text, flags candidate living items based on domain knowledge, and outputs a focused target for subsequent actions like focus on or pick up.

Quality

Content

86%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 concise, actionable, and clearly sequenced, with a concrete worked example. Its main weakness is progressive disclosure: the body duplicates (in abbreviated form) content that exists in references/living_indicators.md and never points to either bundle reference file, one of which (action_sequences.md) is an empty stub.

Suggestions

Replace the inlined animal/egg/plant indicator lists in 'Identify Candidates' with a pointer to references/living_indicators.md (e.g., 'See [living_indicators.md](references/living_indicators.md) for the full taxonomy, parsing rules, and room-likelihood table'), keeping only a few illustrative examples inline.

Reference references/action_sequences.md from the workflow or remove it — it currently contains only a heading ('Basic Identification Flow') with no content, so it adds no value as shipped.

Add a lightweight validation step to the workflow, e.g., check the response after `focus on [IDENTIFIED_OBJECT]` and re-identify or teleport to another room if the target was not accepted.

DimensionReasoningScore

Conciseness

The body is lean and assumes competence — e.g., "**Focus on Target:** `focus on [IDENTIFIED_OBJECT]` to signal task progress" — with no explanations of concepts Claude already knows and no padding, matching the score-5 anchor; the only quibble is the near-duplicate of "signal task progress" in the notes, which does not reach the score-4 anchor's 'several unnecessary explanations'.

5 / 5

Actionability

Concrete, directly executable commands appear throughout ("`look around`", "`teleport to outside`", "`focus on dove egg`", "`pick up dove egg` then `move dove egg to blue box`") and the worked example covers the common case end-to-end, matching the score-5 'copy-paste ready, specific examples cover common cases' anchor.

5 / 5

Workflow Clarity

The four-step Core Workflow is clearly sequenced and includes a fallback ("If the current room lacks candidates, `teleport to` rooms with higher biological likelihood"), but there is no validation checkpoint confirming that `focus on` succeeded before proceeding, matching the score-4 'most checkpoints present; minor validation gaps' anchor rather than score 5's explicit validation steps.

4 / 5

Progressive Disclosure

The bundle contains references/living_indicators.md (an expanded indicator taxonomy with parsing rules and room likelihoods) and references/action_sequences.md, but the body never references either file and instead inlines its own shorter indicator lists, matching the score-3 anchor ('content that should be separate is inline' / references not clearly signaled). It is not score 4 because the existing references are entirely unsignaled rather than 'mostly clear', and not score 2 because the inlined content is brief and the sections themselves are well organized.

Description

92%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 strong: it uses third-person voice, states concrete capabilities with examples, and includes an explicit 'Use this skill when...' clause with natural trigger phrases. The only weakness is modest synonym coverage in its trigger terms.

DimensionReasoningScore

Specificity

Quotes like "Analyzes room observations to identify potential living things (e.g., eggs, plants, animals)", "Processes observation text, flags candidate living items", and "outputs a focused target" list multiple concrete actions with comprehensive coverage for this niche, matching the score-5 anchor rather than the score-4 anchor (which expects minor coverage gaps).

5 / 5

Completeness

It explicitly answers both "what" ("Analyzes room observations... flags candidate living items... outputs a focused target") and "when" ("Use this skill when a task involves finding, focusing on, or interacting with a living thing") with concrete trigger phrases, matching the score-5 anchor exactly.

5 / 5

Trigger Term Quality

"Use this skill when a task involves finding, focusing on, or interacting with a living thing, biological entity, or organism" provides good natural keyword coverage, but common variations like "creature", "animal", or "life" are missing, matching the score-4 rather than score-5 anchor.

4 / 5

Distinctiveness Conflict Risk

"room observations", "living thing, biological entity, or organism", and "eggs, plants, animals" carve out a clear niche with distinct triggers, so it is unlikely to fire for unrelated skills; this matches the score-5 anchor rather than score 4, which expects minor overlap risk with closely related skills.
