AB mermail-cli

Install and use the official Mermail CLI for deterministic shell automation across workspaces, mailboxes, email, folders, labels, agents, task triage, and Agent Wallet via MCP OAuth. Use when a user asks for terminal commands, scripts, CI automation, or stable JSON output. Prefer direct Mermail MCP skills when no shell composition is needed.

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

    • note edit-residue the text marks something as outdated (lines 26, 35, 36, 61): check that old rules are not kept next to new ones — the full check reads the text for contradictions

    Process rating: all ten parameters 66/100

    • 30Inputs and preconditions. Does not say what the process needs to start
    • 30Running it twice. 8 mutating operations with no state check
    • 50When it triggers. No condition that starts the skill
    • 50Failures and branches. 0 branches, has a failure section
    • 60Tools and files. Uses tools (bash) that frontmatter does not declare
    • 60Result and completion. Output format stated, no completion criterion
    • 100Steps. 38 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 1650 tokens
    • 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.

    External checks

    ClawHub: clean
    This skill is a disclosed Mermail CLI helper with high-impact email and wallet capabilities, but its instructions consistently require bounded reads, explicit approval for writes, and careful secret handling.
