Trivia
Some sub-sessions are too short or too quiet to say anything about your work — a stray prompt, a quick look at a file, an aborted start. Scoring those would only add noise. The substance floor catches them and routes them here, to the Trivia bucket.
Headline — exclusion rate
Section titled “Headline — exclusion rate”Share of sub-sessions in the selected range that fell below the substance floor. Lower is calmer, but very low values can also mean you only run heavy sessions.
exclusion_rate = excluded_sub_sessions / total_sub_sessionsA high exclusion rate is not bad — it just means a lot of your sub-sessions are exploratory. If real work is landing in Trivia, that is a sign the floor is too strict and worth flagging.
Reasons
Section titled “Reasons”A sub-session lands in Trivia when any of these is true:
| Reason | What triggered it |
|---|---|
| No real work | No turns, no code change, and no mutating tool calls |
| Too few turns | Conversation ended before reaching the minimum turn count |
| Too few lines changed | Net lines of code changed stayed below the substance floor |
| No mutating tool calls | No write, edit, or run-style tool calls were observed |
| Other | Excluded by the substance floor for a reason not listed |
Why it matters
Section titled “Why it matters”Excluded sub-sessions do not pull your grade up or down — they are pulled out of both numerator and denominator. Trivia is kept visible so you can spot the rare case where real work was caught by mistake. If you see one, flag it.
