AB email_sender
Send email through SMTP providers such as 126, QQ, Sina, or Aliyun Mail using an SMTP authorization code or mailbox password. Use when the user wants Codex to scaffold SMTP mail sending, configure a `.env` file, or send a simple test email.

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.

Against the Agent Skills spec
- warning
name-formatname should be kebab-case (lowercase letters, digits, hyphens)
Process rating: all ten parameters 65/100
- 0Result and completion. Does not say what the result is
- 0Progress reporting. Says nothing while it works
- 40Consistency. Frontmatter name (email_sender) differs from the folder (email-agent)
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 48 steps
- 100Failures and branches. 2 branches, has a failure section
- 100Execution cost. Instruction body is 1145 tokens
- 100Running it twice. Mutating operations check current state
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 13 top-level sections: this looks like several domains in one skill
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
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- +1No license
- +2Single-language instructions
- +3Description length 240: enough signal without eating the budget
- +4Structure: 14 headings
- +3Step-by-step instructions: 48 items

ClawHub: suspicious
This SMTP email skill mostly does what it says, but its fallback configuration can mishandle email credentials and connect to an unintended mail provider unless settings are fully specified.
