AC db-travel
Plan journeys across Germany and Europe using the Deutsche Bahn API (v6.db.transport.rest). Covers ICE, IC, regional trains, S-Bahn, U-Bahn, trams, buses, ferries. Use when: (1) planning trips in Germany or cross-border European rail, (2) checking departure/arrival boards at German/European stations, (3) finding station IDs, (4) navigating cities like Berlin, Munich, Hamburg. Triggers on questions about German trains, DB, BVG, getting around Berlin, European rail connections.
As a process C 58/100 · Has gaps — weak spots: result and completion, inputs and preconditions, progress reporting
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 58/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 60Failures and branches. 2 branches
- 70When it triggers. States when to use, but not when not to
- 100Steps. 15 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 523 tokens
- 100Running it twice. No mutating operations
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.
