Conciseness

Lean and efficient throughout: no explanation of what VASP or DPDispatcher are, no padding, and every line states a rule, a file to read, or an output field. Matches the 'every token earns its place' anchor.

Actionability

Concrete, specific guidance: exact tool name ('vasp_execute_batch', with 'do not use deprecated vasp_execute'), exact state file ('_BATCH_STATE.json'), precise layout rules, and a named output contract. For an instruction-only skill the guidance is actionable; not score 5 because there is no example invocation showing argument shapes (e.g., relative input_dir/output_dir values), leaving a minor gap for a first-time execution.

Workflow Clarity

Clear four-step sequence with explicit validation checkpoints ('Validate the execution layout' as step 1, 'Read _BATCH_STATE.json first') and an error-recovery feedback loop (inspect focused failure evidence, rerun only the failed subset into a fresh output root). This satisfies the batch-operation validation requirement, so the score-3 cap does not apply; not score 4 because checkpoints are explicit at both pre-submission and post-failure stages.

Progressive Disclosure

The body is under 50 lines, well-organized into Overview/Quick Start/Tools/Workflow/Output Contract sections, no bundle files exist, and no references are made to missing files — the 'no need for external references, well-organized sections' condition for a 5 is met. Note the '## References' section contains behavioral guidance about bash usage rather than file references, which is a trivial naming quirk, not a broken navigation link.

Specificity

The description names several concrete actions — 'dispatching prepared VASP jobs with vasp_execute_batch', 'choosing valid input/output layouts', 'avoiding nested or overlapping calc trees', 'collecting clean failure evidence' — anchored to a specific tool. Not score 5 because coverage has gaps: no mention of single-folder vs batch modes, triaging, or rerunning failed subsets, and the layout/tree actions partially overlap.

Completeness

Both 'what' (dispatching prepared VASP jobs, layout choices, failure evidence collection) and 'when' ('Use this skill for dispatching prepared VASP jobs...') are present. Not score 5 because the 'when' is a single implicit domain trigger rather than explicit trigger phrases like 'use when the user asks to run or submit VASP calculations'; not score 3 because the trigger clause is explicitly stated, not merely implied.

Trigger Term Quality

Good keyword coverage with natural terms users would say: 'VASP jobs', 'dispatching', 'batch', 'input/output layouts'. Not score 5 because common synonyms and file-level triggers are missing — a user saying 'run my VASP calculations', 'submit', or mentioning INCAR/POSCAR files would not literally match.

Distinctiveness Conflict Risk

Clear niche: 'VASP jobs', 'vasp_execute_batch', 'calc trees', and 'failure evidence' are highly domain-specific and would not plausibly trigger any other skill. Minimal conflict risk.
