AC pilot-service-agents-transit
Public-transit schedules and live data — Amtrak, BART, Deutsche Bahn, Swiss SBB, BC Ferries, BVG Berlin, and more. Use this skill when: 1. Live train / ferry / bus departures at a specific stop or station 2. Planning a multi-modal journey between two stops (e.g. Swiss SBB, DB) 3. Station directory lookups (Amtrak, Entur geocoder) Do NOT use this skill when: - City bike-share (use pilot-service-agents-traffic) - Aircraft / flight information (use pilot-service-agents-flights) - Road-routing for cars (use pilot-service-agents-geo)
As a process C 63/100 · Has gaps — weak spots: inputs and preconditions, failures and branches, running it twice
What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill asks for more than the task needs: broad tool access, credential environment variables, binaries. Every extra permission widens the damage from a mistake or a compromise.
Narrow allowed-tools and the variable list to the minimum; replace binaries with readable sources or scripts.
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 63/100
- 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
- 30Running it twice. 2 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 60Result and completion. Output format stated, no completion criterion
- 100Tools and files. Tools declared in frontmatter
- 100Steps. 4 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 882 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.
