AF vikunja

Interact with a self-hosted Vikunja task management instance via its REST API. Use when the user asks to create, update, delete, or list tasks/projects/labels, schedule reminders, check due dates, bulk-complete tasks. Also use for "add to my todo list", "remind me to", "schedule X", "what's on my task list", "mark done", "recurring task", or any Vikunja-specific request. Triggers on: task, todo, to-do, reminder, schedule, project, inbox, label, gantt, vikunja, recurring task.

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Exfiltration medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".

For the author

If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.

How to improve

  1. The text references files that are not there: add them or drop the references.
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 missing-ref reference to a missing file: references/vikunja.yaml

Process rating: all ten parameters 41/100

Will not run. References files that are not bundled: references/vikunja.yaml
  • 0Tools and files. 1 referenced file(s) missing: references/vikunja.yaml
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 30Running it twice. 6 mutating operations with no state check
  • 40Consistency. Frontmatter name (vikunja) differs from the folder (self-hosted-vikunja)
  • 50Failures and branches. 0 branches, has a failure section
  • 70When it triggers. States when to use, but not when not to
  • 100Steps. 18 steps
  • 100Execution cost. Instruction body is 1066 tokens
  • 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.

Quality signals

External checks

ClawHub: suspicious
This Vikunja skill is purpose-aligned overall, but it exposes reusable authentication tokens and can delete task/project data without enough safeguards.
