AC shellmail

Full email client for AI agents via the ShellMail API. Read inbox, extract OTP codes, and search messages; also send and reply to email, mark/archive/permanently delete messages, and create, recover, or delete the ShellMail address itself. Uses curl/python3 to reach the ShellMail API only. Trigger ONLY when the user explicitly asks to use ShellMail or their shellmail.ai address (e.g. "check my shellmail", "get the OTP from shellmail", "send from my shellmail address"). Do NOT trigger for generic email requests or other email providers.

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 62/100

    • 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. 42 mutating operations with no state check
    • 60Tools and files. Uses tools (bash, web) that frontmatter does not declare
    • 65Failures and branches. 3 branches
    • 100Steps. 28 steps
    • 100When it triggers. States when to use and when not to
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 2305 tokens
    • 100Progress reporting. Reports progress
    • 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.

    This is a disclosed ShellMail email-client skill with sensitive mailbox powers, but its access is purpose-aligned, scoped, and includes user-confirmation safeguards for destructive actions.
