Conciseness

Lean body where every line earns its place; rules are stated without explaining what grep, sub-agents, or path:line references are, fully assuming Claude's competence.

Actionability

Concrete Good/Bad examples and named commands (grep_files, read_file, deepseek-v4-flash sub-agent) give executable guidance, but the sub-agent snippet is illustrative rather than copy-paste runnable and path:line sourcing is described abstractly.

Workflow Clarity

Three clearly sequenced rules each pair an action with a 'Failure avoided' checkpoint, and rule 2 adds a pre-execution verification gate; minor gap is the absence of an explicit validate-fix-retry feedback loop for the multi-file execution path.

Progressive Disclosure

Under 50 lines with no external references needed; content is organized into three well-signaled sections, matching the simple-skill exception for a top score with just well-organized sections.

Specificity

Names the domain (V4 thinking-mode workflows) and several concrete actions—preventing stale references, unverified plan assumptions, and vague plan output—though these are constraints rather than a fully comprehensive action list.

Completeness

Explicitly answers both 'what' ('Provides rules to prevent stale references, unverified plan assumptions, and vague plan output') and 'when' ('Use when working with deepseek-v4-pro or deepseek-v4-flash in thinking mode on multi-step or plan-driven tasks') with concrete triggers.

Trigger Term Quality

'working with deepseek-v4-pro or deepseek-v4-flash in thinking mode on multi-step or plan-driven tasks' are natural triggers a user would say, though common synonyms like 'planning tasks' beyond 'plan-driven' are thin.

Distinctiveness Conflict Risk

Scoped narrowly to specific named models in thinking mode on plan-driven tasks, giving it a clear niche with minimal overlap risk against general coding skills.
