Conciseness

The body is lean and assumes competence — no concept explanations, just commands and decision rules ('Use `look around` upon arrival', '`activate` the source if necessary'). Not 5 because the 'Quick Reference' section restates the trigger/loop/success already covered, and the room-priority tiers duplicate references/room_priority.md. Clearly above anchor 3, which requires unnecessary explanation.

Actionability

Mostly executable guidance with concrete backticked commands (`look around`, `examine`, `pick up`, `move`, `activate`, `deactivate`) and concrete sub-steps (a-e for fixed sources). Not 5 because the core navigation command is only described as 'Teleport to and survey rooms' — the actual `teleport to LOC` syntax lives solely in the unreferenced action_glossary.md.

Workflow Clarity

A clear 5-step sequence with conditional branches ('If a source is found... proceed', 'If not, find one') and an explicit termination check ('Once the required liquid is successfully obtained and in your inventory, conclude'). Not 5 because feedback loops are missing — e.g., no guidance for re-checking when a found source yields nothing — though this is a simple search skill, not a destructive/batch operation, so no cap applies.

Progressive Disclosure

Sections are well-organized, but the bundle contains references/action_glossary.md and references/room_priority.md and the body never references either — the room-priority tiers and action semantics are inlined instead of delegated, leaving the reference files undiscoverable. This is worse than anchor 4's 'references mostly clear' but better than anchor 2, since the body itself is well-structured rather than a monolith.

Specificity

Lists several concrete actions — 'teleporting to candidate rooms, looking around, and identifying potential sources' — alongside concrete object examples ('sink, toilet, jug'). Not 5 because the liquid-collection half of the skill is absent; not 3 since coverage goes beyond 1-2 actions.

Completeness

Explicitly answers both: what ('searches rooms for a liquid source... by sequentially surveying different locations', 'teleporting... looking around... identifying') and when ('It should be triggered when the task requires obtaining a liquid (like water) and the agent does not have immediate access to it'). The when-clause is explicit with a concrete trigger condition, matching the anchor-5 example structure.

Trigger Term Quality

Includes natural terms a user would say — 'obtaining a liquid (like water)', 'sink', 'toilet', 'jug'. Not 5 because common variations such as 'juice', 'fill', or 'get water' are missing; clearly above anchor 3's partial coverage.

Distinctiveness Conflict Risk

A clear niche — room-by-room survey for liquid sources via teleporting — with distinct triggers ('requires obtaining a liquid', 'does not have immediate access'). Minimal overlap risk with other skills; the described procedure is unlike generic capability descriptions.
