Conciseness

Lean prose that assumes competence and never explains what a deck/chart/EBITDA is; every line carries instruction (e.g., 'the deck is the source of truth for formatting; you're only changing values').

Actionability

Concrete, specific guidance with real worked examples (the change-list and report blocks) and exact rules, but it is instructional rather than copy-paste executable code—appropriate for this skill, with minor gaps in literal commands.

Workflow Clarity

A four-phase sequence with an explicit approval gate (Phase 3) before any destructive edit, plus post-edit visual-verification checks and flagged second-order items—validation and feedback loops are present and emphasized.

Progressive Disclosure

Well-organized sections with a clear overview and no nested references; the skill is self-contained with no bundle files, so structure is good though there is nothing to disclose progressively beyond the single file.

Specificity

Names the domain (deck updates) and several concrete actions—quarterly refreshes, comp rolls, rebased market data, swapping figures—without being fully comprehensive about every edit type.

Completeness

Explicitly states what it does ('Updates a presentation with new numbers...') and when to use it with concrete trigger phrases in a clear 'Use whenever...' clause.

Trigger Term Quality

Comprehensive natural trigger phrases ('update the deck with Q4 numbers', 'refresh the comps', 'roll this forward', 'swap in the new earnings', 'change all the $485M to $512M') that a user would genuinely say, with synonyms covered.

Distinctiveness Conflict Risk

Clear niche—value-swapping across an existing deck without rebuilding it—with distinct triggers that separate it from broader presentation-building or editing skills.
