Conciseness

The ~17-line body is lean and assumes competence: no concept explanations, just the command, a three-step procedure, and operational caveats. Every token is operational; the only near-redundancy (room examples in step 2 repeated in the notes) is trivial. Clearly matches the 'lean and efficient' anchor rather than the 'minor instances of over-explanation' anchor below it.

Actionability

The guidance is copy-paste ready: the exact command format `teleport to <room_name>` with concrete examples (workshop, kitchen, foundry), the expected output observation, and an exact-match requirement for room names. This fully matches the 'fully executable, specific examples cover the common cases' anchor.

Workflow Clarity

This is a simple single-task skill where the action is unambiguous, and it still includes a verification step ("Verify Success: The expected output is an observation confirming the teleport, e.g., 'You teleport to the workshop.'") plus error-avoidance guidance (exact room-name matching). The destructive/batch cap does not apply; this matches the simple-skill exception for a 5.

Progressive Disclosure

The skill is under 50 lines, needs no external references (none exist in the bundle), and is organized into clear sections (Instructions, Procedure, Important Notes) with the room list placed appropriately. This matches the rubric's explicit exception allowing a 5 for short, well-organized, self-contained skills.

Specificity

"Teleports the agent to a specified room" and "takes a target room name as input and outputs a successful teleportation observation" name the domain plus one concrete action with its I/O, but no multiple distinct actions are listed. It is not a 4 because 'several specific actions' are absent, and not a 2 because the action and input/output are concrete rather than generic.

Completeness

Both parts are answered: the what ("Teleports the agent to a specified room within the ScienceWorld environment") and an explicit when ("Use this skill when the target object or location for a task is known to be in a different room"). It is not a 5 because the when-clause is a single abstracted condition rather than a set of concrete trigger phrases, and "enabling efficient navigation" adds mild fluff; clearly above a 3 since the when is explicit, not weakly implied.

Trigger Term Quality

Natural trigger terms are present — "teleport", "room", "target object or location", "in a different room" — matching what a user would say when needing this skill. It is not a 5 because common variations like "go to", "move to", or "navigate to" the room are missing; not a 3 because coverage of the domain's natural phrasing is good rather than partial.

Distinctiveness Conflict Risk

"ScienceWorld environment" plus the teleport action carves out a clear niche with distinct triggers; no plausible overlap with other skills. This matches the anchor for minimal conflict risk exactly.
