AB subscription-app-revenue

Revenue playbook for taking a mobile or web subscription app from zero to early MRR (around $1K). Use when users ask how to make money from an app, reach first subscribers or $1K MRR, validate an app idea against app-store demand, plan ASO, TikTok/Reels/Shorts or Reddit acquisition, choose freemium vs trial vs rewarded unlock, place and word a paywall, price monthly/annual plans, read churn, or diagnose a weak install-to-paid funnel. Do not use for implementing in-app purchase code (capacitor-plugins, @capgo/native-purchases), store submission mechanics (capacitor-app-store), App Review rejections (capacitor-apple-review-preflight), or shipping OTA experiments (capgo-live-updates).

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    • 0Failures and branches. Linear process with no failure handling
    • 30Inputs and preconditions. Does not say what the process needs to start
    • 30Running it twice. 3 mutating operations with no state check
    • 60Result and completion. Output format stated, no completion criterion
    • 100Tools and files. Tools declared in frontmatter

    • 100When it triggers. States when to use and when not to
    • 100Consistency. Name and required fields are in place

    • 100Progress reporting. Reports progress
    • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
