The body is lean throughout: compact tables, tight bullet rules, and no explanation of concepts Claude already knows, so every token earns its place.

Concrete 7-step Core Pattern, a filled Lane Matrix, explicit Execution Rules, and a copy-paste Output Shape template give actionable guidance; per the rubric's instruction-only note, the absence of executable code is not penalized when guidance is this concrete.

The Core Pattern is a clearly sequenced 7-step process with explicit validation checkpoints (merge only after evidence, end with a verification table) and a feedback loop (pause dependent lanes on a blocker), satisfying the batch-operation validation requirement.

No bundle files are needed; the skill is self-contained and well-organized into clear sections (Core Pattern, Lane Matrix, Execution Rules, Output Shape, Failure Modes), which meets the bar for a simple skill with no external references.

Lists multiple concrete mechanisms ('parallel work, concurrent agents, batched tool calls, isolated worktrees... many independent verification lanes'), matching the anchor for multiple specific concrete actions rather than a partial domain mention.

An explicit 'Use when...' clause supplies the trigger, and the rest states what it does (faster parallel execution without losing correctness), clearly answering both what and when.

Natural terms like 'parallel work', 'concurrent', and 'task done much faster' appear, but 'batched tool calls', 'isolated worktrees', and 'verification lanes' are Claude-internal jargon a user would rarely say, so coverage of natural phrasing is incomplete.

The parallelization-orchestration niche with mechanism-specific triggers (worktrees, concurrent agents, verification lanes) is distinct from typical domain skills and unlikely to fire for the wrong skill.
