What Discernment nudge does

Discernment nudge gives the agent a short closing step for answers a user is likely to act on. After it gives advice, an estimate, an analysis of data, factual claims or a drafted plan, pitch, proposal or email, the agent decides whether a nudge fits. If it does, the reply ends with the lead-in line "A few things worth a second look:" and two or three plain bullets. Each bullet is a short first-person question tied to a specific number, step or assumption in the answer, written so the user could send it back as is.

The questions model three habits that the SKILL.md takes from the AI Fluency framework: checking facts, questioning reasoning and noticing missing context. The nudge appears at most once per conversation, and nothing follows it.

Much of the file covers when to stay quiet. Creative writing, casual chat, simple lookups, purely educational explanations and code the user will run get no nudge. The same goes for replies where the user asked for verification or sources, wanted the quick version, asked the agent to review their own work, supplied the material being summarized, or asked for an opinion. The result is a normal answer that sometimes ends with a few targeted questions.

Read the security check below before you run it. The repository's own instructions win if they differ.

Security check

What the skill's files do, from reading them. A flag that nobody has checked yet says "Not checked", never "No".

The scan found no scripts, no hooks, no network calls and no secret variables. The folder holds only SKILL.md and LICENSE.txt, and the skill is plain instructions: it changes how the agent ends some replies by adding two or three follow-up questions. It fetches nothing and has no steps that touch local files. Before installing, read SKILL.md to confirm its trigger rules match how you want replies to end, since it can fire after many kinds of substantive answers.

Scan details: No scripts, hook definitions, network calls or secret variables were found in the skill folder. Checked at commit dbd4588f9e10.
