Convert Bullshit Filter - The Adversarial Coaching Pass

"Would I actually say this to someone I'm trying to help?" - The Donahoe Method, Voice Rules

The Bullshit Filter is one question. It's also the single most important question in the Method.

This skill runs the Filter as an adversarial coaching pass - not a verdict. It refuses to grade copy as "passed" or "failed." Instead, it forces three concrete actions on every draft:

1. Quote the 3 weakest lines in the draft, even if the draft seems strong. There is always a worst sentence; this skill identifies it.
2. Produce 3 alternative rewrites of each weakest line, so the writer sees the actual menu of voicing choices instead of accepting an AI's first take.
3. Diagnose the dominant voice failure pattern in one paragraph (e.g., softeners, marketing-speak, abstract language, hedged claims, performative urgency).

The output is a coaching artifact. The user decides whether to ship after seeing the 3 weakest lines + 9 rewrites + the diagnosis. There is no PASSED, no FAILED, no boolean stamp. AI cannot grade its own work; this skill stops trying.

When to Use

Trigger phrases: "bullshit filter", "run the filter", "donahoe filter", "would I say this to a friend", "read aloud test", "kill anything that sounds fake", "final voice gate", "last pass before shipping", "find the weakest lines", "rewrite the worst sentences", /convert bullshit-filter <draft>.

Use this skill as the last coaching pass before shipping. Run it AFTER:

• convert-open has produced the open
• convert-three-locks has architected the persuasion
• convert-bullets, convert-proof, convert-close have produced the body and close
• convert-chute has engineered momentum
• convert-voice has applied the Voice Rules
