Activate when: user says 'our growth is stalling and we don't know why,' 'product and marketing are arguing about whose fault it is,' 'where is our funnel breaking,' 'pirate metrics,' or 'acquisition vs activation vs retention.' Also activate for: designing end-to-end metrics for a new product, building a shared instrumentation framework across teams. Do NOT activate when: the product has no users yet (use lean-startup instead), or the bottleneck is already obvious and obvious to fix. More: deciqai.com/c/aarrr-pirate-metrics

As a process C 57/100 · Has gaps — weak spots: when it triggers, inputs and preconditions, failures and branches
How to improve
- 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.

Process rating: all ten parameters 57/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 5 mutating operations with no state check
- 60Result and completion. Output format stated, no completion criterion
- 85Steps. 38 steps, 1 vague phrases
- 100Tools and files. No external tools needed
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 2127 tokens
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.
