AC Bitwarden / Vaultwarden
Bitwarden & Vaultwarden password manager integration. Use when storing, retrieving, generating, or managing passwords and credentials. Wraps the Bitwarden CLI (bw) with automatic session management. Works with both official Bitwarden and self-hosted Vaultwarden servers.
As a process C 54/100 · Has gaps — weak spots: result and completion, when it triggers, consistency
How to improve
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.

Process rating: all ten parameters 54/100
- 0Result and completion. Does not say what the result is
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 10 mutating operations with no state check
- 40Consistency. Frontmatter name (Bitwarden / Vaultwarden) differs from the folder (twhidden-bitwarden)
- 55Failures and branches. 1 branches
- 60Tools and files. Uses tools (bash, web, node) that frontmatter does not declare
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 29 steps
- 100Execution cost. Instruction body is 1326 tokens
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 12 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (3 tags): a typed call is more reliable
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.

External checks
ClawHub: suspicious
This appears to be a real Bitwarden/Vaultwarden integration, but it gives an agent broad ability to read, create, edit, and delete vault credentials without built-in confirmations.
