AB Vincent - Credentials for agents
Secure credential management for agents. Use this skill when users need to store API keys, passwords, OAuth tokens, or SSH keys and write them to .env files without exposing values. Triggers on "store credentials", "API key", "manage secrets", "write to env", ".env file", "credential", "password", "token storage".

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 73/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 40Consistency. Frontmatter name (Vincent - Credentials for agents) differs from the folder (vincent-credentials)
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 85Steps. 16 steps, 1 vague phrases
- 100Tools and files. Tools declared in frontmatter
- 100Failures and branches. 3 branches, has a failure section
- 100Execution cost. Instruction body is 2286 tokens
- 100Running it twice. Mutating operations check current state
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
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.
