Lean body with no padding or explanation of concepts Claude already knows; each line is direct actionable guidance. The brief Overview and opening "Based on..." line slightly restate the description but remain efficient.

Provides concrete, specific behavioral instructions such as "Request more troops than seemingly necessary," "Refuse all challenges to battle," and "When soldiers start 'throwing stones and jumping distances' they are ready," which is actionable instruction-only guidance rather than vague direction.

Presents a clear five-step sequence with an explicit Validation section containing verification checkpoints — distinguishing genuine withdrawal from feigned retreat and confirming full commitment of pursuit forces.

Under 50 lines, single-task, with no bundle files and well-organized sections (Overview, Steps, Expected Outcomes, Validation), which qualifies for a top score under the simple-skills allowance.

Lists multiple concrete actions — "commanding a large army," "planning patient siege warfare," "refusing battle," "maintaining troop welfare through recreation and shared conditions," and "striking when the enemy withdraws" — rather than vague language.

Explicitly answers both what (the patient-siege warfare approach anchored to Wang Jian's Chu conquest) and when ("Use when commanding a large army against a determined enemy or planning patient siege warfare").

Includes natural terms a user would say for this niche — "large army," "determined enemy," "siege warfare," "troops" — with good coverage of the domain's common phrasings.

The niche is highly specific — large-force patient siege warfare tied to a named historical campaign — making it unlikely to trigger for unrelated skills.
