unit-economics

Analyze unit economics for PE targets — ARR cohorts, LTV/CAC, net retention, payback periods, revenue quality, and margin waterfall. Essential for software/SaaS, recurring revenue, and subscription businesses. Use when evaluating revenue quality, building a cohort analysis, or assessing customer economics. Triggers on "unit economics", "cohort analysis", "ARR analysis", "LTV CAC", "net retention", "revenue quality", or "customer economics".

Quality

Content

68%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is a well-structured, mostly lean analytical methodology with concrete formulas, benchmarks, and a clear step sequence. Its main weakness is the absence of explicit validation checkpoints in the workflow, which leaves workflow clarity at the midpoint.

Suggestions

Add explicit validation/verification checkpoints to the workflow — e.g., after Step 2 (Core Metrics), a check that ARR bridge components reconcile (Beginning + New + Expansion − Contraction − Churn = Ending), and after Step 4, a cross-check that cohort-implied retention is consistent with reported NDR.

Provide the missing payback-period formula and a concrete example of the ARR bridge computation so the actionability guidance is complete for every metric named.

Tighten the introductory transition phrases (e.g., "Determine the revenue model to tailor the analysis:", "Synthesize into a revenue quality assessment:") to improve token efficiency.

DimensionReasoningScore

Conciseness

The body is dense, structured reference material (bullet lists, tables, benchmark thresholds) that mostly assumes financial competence and avoids explaining what ARR/LTV is; a few introductory phrases ("Determine the revenue model to tailor the analysis", "Synthesize into a revenue quality assessment") could be trimmed, keeping it just above a 3.

4 / 5

Actionability

Gives concrete, specific guidance appropriate to an instruction-only analysis skill — exact formulas (LTV = (ARPU × Gross Margin) / Churn Rate), explicit benchmark thresholds (Rule of 40 > 40%, NDR >120%/110%/<100%), and defined output tables — with minor gaps (e.g., no explicit payback-period formula).

4 / 5

Workflow Clarity

A clear five-step sequence (Identify Model → Core Metrics → Benchmarking → Quality Score → Output) is present, but there are no explicit validation/verification checkpoints or feedback loops; quality checks exist only as implicit notes in "Important Notes", matching the anchor for steps-with-validation-gaps.

3 / 5

Progressive Disclosure

No bundle files exist, and the self-contained methodology is well-organized into clear sections with tables and headers and no nested references; minor organization gaps (benchmark reference tables inline) keep it just under a 5.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is third-person, concise, and explicitly answers both what the skill does and when to use it, supported by a comprehensive list of natural trigger phrases. It is a strong example with no notable gaps.

DimensionReasoningScore

Specificity

Lists multiple concrete analysis actions — "ARR cohorts, LTV/CAC, net retention, payback periods, revenue quality, and margin waterfall" — giving comprehensive coverage of the unit-economics domain rather than vague language.

5 / 5

Completeness

Explicitly states both what it does ("Analyze unit economics for PE targets...") and when to use it ("Use when evaluating revenue quality, building a cohort analysis, or assessing customer economics. Triggers on...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Provides a rich set of natural trigger phrases a PE/SaaS user would actually say ("unit economics", "cohort analysis", "ARR analysis", "LTV CAC", "net retention", "revenue quality", "customer economics"), including synonyms and variations.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (unit economics for PE/SaaS targets) with specialized, domain-specific triggers unlikely to fire for unrelated skills; minimal conflict risk.
