Conciseness

Lean ~15-line body with no padded explanations of concepts Claude already knows; every line is actionable guidance and each token earns its place.

Actionability

Provides concrete flags and scope guidance (PD_ADDR=127.0.0.1:2379, --pd.port, --port-offset, -run <TestName>), but full canonical commands are deferred to the external doc rather than given copy-paste ready inline.

Workflow Clarity

Clear sequenced 5-step checklist with explicit validation (readiness checks in overview, step 5 verifies teardown via unreachable PD endpoint); missing explicit error-recovery feedback loops keeps it just below 5.

Progressive Disclosure

Well-organized Overview + Workflow Checklist sections with a clearly signaled one-level-deep reference to docs/agents/testing-flow.md; no bundle files exist to verify further, and the external reference is repeated twice, a minor organization gap.

Specificity

Names the domain (tests under tests/realtikvtest) and lists several concrete lifecycle phases ('strict startup, readiness checks, and cleanup'), with only minor gaps in coverage relative to the comprehensive 5-anchor example.

Completeness

Explicitly answers both what ('local TiUP playground lifecycle with strict startup, readiness checks, and cleanup') and when ('Use when running tests under tests/realtikvtest') with concrete trigger phrasing.

Trigger Term Quality

Good keyword coverage with natural terms a TiDB developer would say ('running tests', 'tests/realtikvtest', 'TiUP playground'), though a few common synonyms or variations are absent.

Distinctiveness Conflict Risk

Targets a clear niche (realtikvtest suite requiring a TiUP playground lifecycle) with distinct triggers and minimal overlap risk against other skills.
