name: mlb-beginner-translator
description: Converts baseball and fantasy-baseball jargon into plain English for a user with zero baseball knowledge. Wraps every user-facing sentence produced by the MLB agent team (morning briefs, trade recommendations, waiver calls, chat summaries). Detects jargon terms, attaches an inline parenthetical plain-English gloss on first mention in a document, enforces the action-verb ladder (START / SIT / ADD / DROP / BID $X / ACCEPT / COUNTER / REJECT), and rejects assumed-knowledge phrases like "hot streak" or "positive matchup." Use when asked to translate for beginner, explain in plain English, translate this, write without jargon, make it beginner-friendly, or produce any user-facing MLB output for K L D'Souza's Fantasy Baseball 2K25 team.

## Example

**Scenario**: The lineup-optimizer has produced a raw recommendation that needs to be rewritten for the user (K L D'Souza, zero baseball knowledge) before it ships in the morning brief.

**Before (raw, jargon-heavy)**:

> Caminero (TB 3B) has positive platoon splits vs RHP and a plus matchup vs Bello at Fenway (park factor 103 R / 105 HR). His 15-day xwOBA is .410 vs a .355 baseline, suggesting a hot streak. OBP contribution is elite given his #3 slot. daily_quality = 66. SB opportunity is middling -- Bello holds runners average but catcher CS% 28%. Regression index +15 on season wOBA gap. START over Hayes (UTIL), who faces a LHP in a bullpen game at Oracle -- negative park, low opportunity, QS unlikely (trivially, he is a hitter; what I mean is his slate has low floor). Verdict: START Caminero, SIT Hayes.

**After (beginner-translated)**:

> **Junior Caminero (Tampa Bay, third base)** -- **START** him today.
>
> Why: he hits right-handed pitchers well (most batters hit better against pitchers who throw from the opposite hand), and today's opposing pitcher (Brayan Bello) throws right-handed. The stadium (Fenway Park in Boston) also favors hitters -- it gives about 3% more runs and 5% more home runs than an average park. On top of that, Caminero has been hitting well lately (his expected-hitting quality over the last 15 days is about 15% above his season average), and he is batting third in the lineup (more times at the plate = more chances to score). Stealing a base today is a coin flip -- the Boston catcher throws out runners at a decent rate, so we are not counting on it.
>
> **Ke'Bryan Hayes (Pittsburgh, third base, in your utility slot)** -- **SIT** him today.
>
> Why: he faces a left-handed pitcher, which is the harder matchup for him, and the game is at Oracle Park in San Francisco (a cold, big-outfield park that suppresses hitting). The opposing team is also using a **bullpen game** (no single starter -- they cycle relief pitchers all game), which tends to produce fewer big hitting opportunities.
>
> **Actions:**
> - **START** Caminero at 3B.
> - **SIT** Hayes (move him to bench, BN).

**What the translator did**:

1. Detected 11 jargon terms (RHP, platoon splits, park factor, xwOBA, OBP contribution, daily_quality, SB, CS%, regression index, bullpen game, QS) and either glossed each on first use or rewrote around them.
2. Rewrote "hot streak" as "has been hitting well lately" (see [Guardrails #2](#guardrails)).
3. Dropped internal agent signals (`daily_quality = 66`, `regression_index = +15`) -- these are inputs, not output.
4. Collapsed the decision to action verbs (**START** / **SIT**) at the end.
5. Kept position abbreviations (3B, BN) only after the position was spelled out in parentheses on first use.
6. Removed the self-correction ("trivially, he is a hitter...") -- the user does not need to see the agent debating itself.
