The body is lean with short bullets and no padding or explanation of concepts Claude already knows; illustrative details like 'three zhang tall' and the gold figures concretize rather than pad, matching 'lean and efficient; every token earns its place'.

For an instruction-only skill it gives concrete, specific guidance with worked example values (specific pole placement, verbatim announcement text, 10→50 gold figures), and per the rubric's scoring notes actionable instruction-only guidance is not penalized for lacking code.

A clear numbered five-step sequence is paired with a dedicated Validation section containing three explicit verification checkpoints (public witness, immediate visible payment, compliance-rate assessment), matching 'clear sequence with explicit validation steps'.

The skill is under 50 lines, needs no external references, and is organized into clear sections (Overview, Steps, Key Principle, Expected Outcome, Validation), which per the rubric's simple-skills note lets progressive disclosure score 3 on well-organized sections alone.

It names the domain and concrete actions ('creating a simple public task with escalating rewards to demonstrate that government promises are kept') but describes one technique conceptually rather than enumerating multiple distinct concrete actions, matching the anchor for 'names domain and some actions, but not comprehensive'.

It explicitly answers both when ('Use when launching major policy reforms or establishing trust before implementing new laws') and what (the escalating-reward public-task method), satisfying the anchor for clearly answering both what AND when with explicit triggers.

Natural phrases like 'launching major policy reforms', 'establishing trust', and 'implementing new laws' are present, but coverage is narrow and the jargon term 'Shang Yang's 徙木立信 method' is not something most users would naturally say, fitting 'some relevant keywords but missing common variations'.

The skill occupies a clear niche — credibility/trust-building before policy reform tied to a named historical method — with distinctive triggers unlikely to fire for unrelated skills, matching 'clear niche with distinct triggers; unlikely to conflict'.
