Conciseness

The body is dense and prescriptive throughout (section rules, tables, good/bad examples) and never explains concepts Claude already knows, but the "## Keywords" section lists 12 trigger phrases that duplicate the frontmatter description's job and add no executable guidance. That is minor trimmable padding, placing it between the 3 and 5 anchors, closer to lean-and-efficient.

Actionability

For an instruction-only skill the guidance is fully executable: "3 sentences. No more.", "6-8 metrics max. Use a table." with a filled example table, a good/bad executive-summary pair, a 5-step bad-news script with example phrasings, and "High confidence $2.6M, upside to $2.9M..." forecast formatting. Specific examples cover the common cases (quarterly, monthly early-stage, fundraising) via the Cadence Notes.

Workflow Clarity

A clear sequence exists (Quick Start invocation → 11 sections in standard order → 4-act narrative → cadence variant), and per-section constraints ("The forecast must have a confidence level", "One sentence on each variance") plus the mistakes table act as implicit checkpoints. It falls short of 5 because there is no explicit final validation/review step; deck building is not a destructive or batch operation, so the cap of 3 does not apply.

Progressive Disclosure

The body is well-organized with clear section headers and a clearly signaled References section, but it cites "references/deck-frameworks.md" and "templates/board-deck-template.md", neither of which exists in the bundle (no references/ or templates/ directories are present). Additionally, the full 11-section deck specification is inlined in SKILL.md even though the (missing) template file is described as the fill-in home for that detail — matching the 3 anchor's "references present but content that should be separate is inline".

Specificity

"Assembles comprehensive board and investor update decks by pulling perspectives from all C-suite roles" names concrete actions, and "Covers structure, narrative framework, bad news delivery, and common mistakes" enumerates scope, but the coverage is topic-level rather than action-level (no mention of metrics dashboards or cadence variants). This sits between the 3 anchor (1-2 concrete actions, not comprehensive) and the 5 anchor (multiple specific actions, comprehensive), noticeably above the midpoint.

Completeness

It clearly answers "what" ("Assembles comprehensive board and investor update decks by pulling perspectives from all C-suite roles") and explicitly answers "when" with concrete trigger scenarios ("Use when preparing board meetings, investor updates, quarterly business reviews, or fundraising narratives"). This matches the 5 anchor's pattern of explicit what-and-when with concrete trigger phrases.

Trigger Term Quality

"Use when preparing board meetings, investor updates, quarterly business reviews, or fundraising narratives" includes natural phrases a user would say. Common synonyms like "board deck", "board pack", "QBR", and "investor pitch" are missing from the description itself (they appear only in the body's Keywords section), so it falls just short of the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Board and investor update decks tied to C-suite roles is a clear niche with distinct triggers ("board meetings", "quarterly business reviews", "fundraising narratives"), matching the 5 anchor: minimal conflict risk with other skills. It is written in third person ("Assembles"), so no voice penalty applies.
