Conciseness

The body is lean — a pipeline diagram, a copy-paste output template, a 7-step workflow, and short routing sections — with every section carrying operational weight. Not a 5 because the one-line tagline ("Where most decisions die: between 'we decided' and 'what's next Monday?'") and the "Why 90 Days" rationale section are mild padding Claude does not need to execute the task.

Actionability

Fully executable guidance for an instruction-only skill: a complete output template with placeholders and a concrete save path (~/.claude/execution/YYYY-MM-DD-<slug>.md), a specific 7-step workflow with numeric constraints (3-6 workstreams, 12 weekly milestones, 30/60/90 checkpoints), and explicit routing commands. Nothing remains pseudocode or hand-wavy.

Workflow Clarity

The workflow steps 1-7 are clearly sequenced and the output template's Definition of Done and kill-criteria checkpoints provide most checkpoints. Not a 5 because there is no explicit validation step before saving (e.g., verify every week 1-12 has a milestone and every workstream has a named DRI), and "Save and notify DRIs" gives no mechanism for notification — minor validation gaps per the anchor.

Progressive Disclosure

Good single-file structure with well-labeled sections (Input, Output, Workflow, Routing, Related) and one-level-deep cross-links to related skills and the cs-coo-advisor agent. Not a 5 because the "Related" links (../../../c-level-advisor/skills/... and ../../agents/cs-coo-advisor.md) resolve outside this standalone bundle where those files are not present, leaving navigation partially unverifiable.

Specificity

"Generate a 90-day execution plan with weekly milestones, DRIs, and check-in cadence from an approved decision" names the domain plus several concrete deliverables (weekly milestones, DRIs, check-in cadence), matching the 'several specific actions; minor gaps' anchor. Not a 5 because it names one generating action whose components are enumerated rather than multiple distinct operations, and some capabilities present in the body (risk register, dependencies) are not mentioned.

Completeness

The description explicitly answers both questions: what ("Generate a 90-day execution plan with weekly milestones, DRIs, and check-in cadence") and when ("Use when a logged decision needs to become an operating plan — e.g. turning an approved market-entry call into weekly milestones"), with a concrete trigger phrase and example. This matches the top anchor exactly; it is not a 4 because the 'when' clause is explicit and specific rather than merely adequate.

Trigger Term Quality

Natural phrases users would say include "execution plan", "90-day", "weekly milestones", "turning an approved market-entry call into weekly milestones", and "operating plan" — good keyword coverage per the anchor. Not a 5 because common synonyms like "action plan", "implementation plan", "roadmap", or "project plan" are absent.

Distinctiveness Conflict Risk

The command namespace (/cs:execute) and the niche trigger — converting an already-approved decision into an operating plan — make it mostly distinct with minor overlap risk against generic planning skills. Not a 5 because bare terms like "execution plan" or "DRIs" could plausibly fire for general planning requests outside the cs pipeline.
