AC vestafolio-rentabilite-locative
Compute gross and net rental yield and monthly cash-flow for a French buy-to-let investment from acquisition cost, rent and annual charges using Vestafolio's simulator API, after asking the simulator's questions (price, notary fees, works, rent, taxe foncière, copropriété, other charges, management fees, vacancy). Use when a user asks about rental profitability, "quelle rentabilité locative", rendement brut vs net, cash-flow of an investissement locatif, or whether a rental property is a good deal.

As a process C 56/100 · Has gaps — weak spots: when it triggers, inputs and preconditions, running it twice
The same skill appears in 1 more place: ClawHub
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 56/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 13 mutating operations with no state check
- 60Tools and files. Uses tools (bash, web, python) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 60Failures and branches. 2 branches
- 85Steps. 32 steps, 1 vague phrases
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1638 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.
