AB new-manager-first-90-days

Plan your first 90 days as a new manager — build trust, learn before changing, and avoid the classic first-time-manager mistakes. Use when asked to help me as a new manager, I just became a manager, first-time manager advice, or my first 90 days managing a team. Produces a phased 90-day plan (listen and learn, then set direction, then adjust), how to run your first 1:1s, the mindset shift from doer to enabler, common traps to avoid (doing it all yourself, changing too fast, avoiding hard conversations), and early wins that build credibility.

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 67/100

    • 0Failures and branches. Linear process with no failure handling
    • 0Progress reporting. Says nothing while it works
    • 20When it triggers. No condition that starts the skill
    • 30Running it twice. 1 mutating operations with no state check
    • 60Result and completion. Output format stated, no completion criterion
    • 70Inputs and preconditions. Inputs and preconditions are listed
    • 100Tools and files. No external tools needed
    • 100Steps. 33 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 1090 tokens

    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.
