Conciseness

Lean and efficient with no padding or explanation of finance concepts Claude already knows; the single driver example earns its place by illustrating the why-vs-what distinction.

Actionability

Concrete guidance throughout — explicit threshold with default, fully specified output table, named data source (internal-gl MCP), and a defined fallback — but no executable call syntax for the MCP, leaving minor gaps.

Workflow Clarity

Clear sequence from inputs through thresholding, per-line table rows, driver sourcing, and output, with an explicit validation guardrail ('driver unclear — flag for controller'); lacks a full feedback loop or completion checklist.

Progressive Disclosure

Under 50 lines with no need for external references and well-organized sections (Threshold, per-line table, Sourcing, Output), meeting the simple-skill exception for a top score.

Specificity

Names the domain and several concrete actions ('write flux commentary', 'current vs prior period and vs budget', 'driver explained from underlying activity'), but it is one composite task rather than multiple distinct operations, with minor gaps (no output format stated).

Completeness

Explicitly answers both what (write variance commentary for flagged lines with driver) and when ('Use for the month-end close package and management reporting') with concrete trigger phrases.

Trigger Term Quality

Good coverage of natural finance terms ('flux commentary', 'P&L', 'balance-sheet', 'month-end close package', 'management reporting'); a few common variants are missing, e.g. the synonym 'variance' and 'budget vs actuals'.

Distinctiveness Conflict Risk

A clear, narrow finance niche (variance/flux commentary on P&L and balance-sheet lines at month-end close) with distinct triggers and minimal risk of matching unrelated skills.
