The body is lean and assumes competence—each section is a short bulleted directive with copy-ready quoted templates and no padding explaining what an analogy or petition is—so every token earns its place.

It gives concrete, executable guidance: named template patterns ("Ruler X obtained Person Y from Place Z"), a reductio structure ("If X were true, then Y would follow"), and copy-paste-ready quoted phrasings, which for an instruction-only skill qualifies as fully actionable.

The six petition sections are clearly sequenced, and the closing "## Verification" section provides explicit confirmation checkpoints, giving the multi-step process a clear sequence with validation steps.

The skill is a single self-contained document with no bundle files; it is well-organized into clearly labeled sections with no nested references, which for a single-purpose skill is appropriately structured.

The description lists multiple concrete techniques the skill combines—"historical precedent, analogical reasoning (reductio ad absurdum), cost-benefit analysis, and principle appeals"—matching the anchor for several specific concrete actions rather than a single domain/action.

It explicitly answers what the skill does (combines the four named argumentative techniques) and when to use it via the explicit "Use when writing persuasive petitions to reverse policy decisions" trigger clause.

It includes relevant natural terms like "writing persuasive petitions" and "reverse policy decisions," but lacks common variations (e.g., "appeal a decision," "letter to officials") and leans on jargon ("reductio ad absurdum"), so coverage is partial rather than comprehensive.

The niche—persuasive petitions to reverse policy decisions, anchored to Li Si's work—is narrow and distinct, with triggers unlikely to collide with other skills.
