BC duplicati
Manage Duplicati backups on the server using secure Bearer tokens.
As a process C 50/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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.

Against the Agent Skills spec
- warning
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 50/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 20When it triggers. No condition that starts the skill
- 40Consistency. Frontmatter name (duplicati) differs from the folder (duplicati-skill)
- 60Tools and files. Uses tools (web) that frontmatter does not declare
- 65Failures and branches. 3 branches
- 100Steps. 6 steps
- 100Execution cost. Instruction body is 390 tokens
- 100Running it twice. No mutating operations
- 100Progress reporting. Reports progress
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.

- +4Description does not say when NOT to use the skill (false activations)
- +3Description length 66: 120–800 characters recommended
- +3Output format is not stated: the model decides each time
- +1No license

ClawHub: suspicious
The skill does what it claims, but its setup encourages a long-lived backup-administration token to be used over plain HTTP without adequate safety guidance.
