CC moving-laterally-with-netexec

Use NetExec (nxc) to validate credentials, enumerate SMB shares/users/policy, password-spray safely across lockout thresholds, execute commands, and dump SAM/LSA/NTDS credentials across SMB, WinRM, LDAP, MSSQL, SSH, and other protocol modules. Use during authorized internal penetration tests to find lateral-movement paths after obtaining credentials or hashes, or to conduct controlled password spraying and post-exploitation on in-scope hosts.

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 61/100

    • 0Result and completion. Does not say what the result is
    • 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
    • 70Inputs and preconditions. Inputs and preconditions are listed
    • 100Tools and files. No external tools needed
    • 100Steps. 26 steps
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 2450 tokens
    • 100Running it twice. No mutating operations

    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.
