Conciseness

The body is lean and avoids explaining concepts Claude already knows, but the Decision Points and Expected Outcomes sections mildly restate content already in the Steps, leaving minor instances that could be trimmed.

Actionability

Each step gives concrete, specific guidance (e.g., "Present beautiful women and treasures to corrupt officials"), but as an instruction-only strategy skill it stops just short of fully copy-paste-ready specificity for the common cases.

Workflow Clarity

The 7-step sequence is explicit, with a Decision Points section providing pivot/feedback loops and a three-item Verification checklist serving as validation checkpoints.

Progressive Disclosure

At under 50 lines with no need for external references, the body is well-organized into clearly labeled sections (Overview, Steps, Decision Points, Expected Outcomes, Verification), satisfying the simple-skill exception.

Specificity

The description lists multiple concrete actions — "offering humble submission, deploying skilled negotiators like Zhong, bribing corruptible enemy officials (Tai Zai Pi), and leveraging credible threats of mutual destruction" — giving comprehensive coverage of the approach.

Completeness

It explicitly answers both what (the four negotiation tactics) and when ("Use when negotiating survival after military defeat") with a concrete trigger phrase.

Trigger Term Quality

"negotiating survival after military defeat" provides good natural trigger phrases, but common synonyms like "surrender" or "capitulation" are absent, leaving a few natural terms missing.

Distinctiveness Conflict Risk

The historical Goujian-of-Yue framing carves out a clear, highly specific niche with distinct triggers and minimal overlap risk against other skills.
