diagnose-activation

Diagnose where new users fail to activate, identify the aha moment, measure time-to-value, and build a sized plan to move activation rate. Use when a PM needs to understand why signups don't convert to active users, find the aha moment, reduce time-to-value, or improve onboarding.

Content

85%

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

A tightly structured, highly actionable activation-diagnosis prompt with clear sequencing and validation checkpoints. Its only weakness is mild redundancy between the description, the bold summary, and the intro paragraph.

Suggestions

Collapse the bold opener and the intro paragraph into a single concise framing line to avoid restating the description.

Trim explanatory asides inside the prompt (e.g. the 90%-on-100-vs-70%-on-10000 illustration) where the instruction already conveys the principle.

Dimension	Reasoning	Score
Conciseness	Mostly efficient domain-specific guidance with little generic concept padding, but the bold opener ("Find where new users fall off...") and the following intro paragraph largely restate the description, and the prompt template runs long enough that it could be tightened without losing clarity.	2 / 3
Actionability	Gives concrete, executable instruction with real math ("Signups x Step 1 Rate x Step 2 Rate = Activated Users") and contrastive examples ("Add a guided template selector as step 2" vs. "improve the onboarding experience"), fully actionable for an instruction-only skill.	3 / 3
Workflow Clarity	A precise 5-step sequence (Define Activation → Measure Funnel → Identify Blockers → Model Impact → Recommend Play) with explicit validation checkpoints ("stress-test it... If the answer is unclear or no, the definition is wrong") and a closing open-questions deliverable.	3 / 3
Progressive Disclosure	No bundle files exist, and the content is cleanly sectioned (Prompt Template, Steps 1–5, Output Format, Tips) with no material that needs splitting out; the single inline prompt template is the core deliverable and is appropriately kept whole.	3 / 3

Description

100%

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 specific, third-person, and complete, with an explicit trigger clause full of natural terms. It cleanly separates activation diagnosis from adjacent growth skills.

Dimension	Reasoning	Score
Specificity	Names multiple concrete actions — "Diagnose where new users fail to activate, identify the aha moment, measure time-to-value, and build a sized plan to move activation rate" — matching the multi-action anchor rather than the single-domain level below.	3 / 3
Completeness	Explicitly answers both what (diagnose activation, find aha moment, measure time-to-value, build a sized plan) and when via an explicit "Use when a PM needs to..." trigger clause, satisfying the top anchor.	3 / 3
Trigger Term Quality	The "Use when..." clause surfaces natural phrasings a PM would actually say — "signups don't convert to active users", "aha moment", "time-to-value", "onboarding" — with good coverage of common variations.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear activation-diagnosis niche with distinctive triggers (aha moment, time-to-value, signup-to-active conversion) unlikely to fire for unrelated skills.	3 / 3
