objection

objection

convince me, or your idea doesn't ship

---

A Claude Code plugin and agent‑agnostic skill that pressure‑tests your ideas and your code. Built for programmers first — it cross‑examines designs, refactors, migrations, diffs, and pull requests — but works on any proposal (business, product, architecture). It treats every claim, including the implicit "this code is ready to merge", as something that must be defended on the merits. One substantive objection per turn. No approval until every objection is answered. Ends with a shareable VERDICT.

Multi‑agent debate beats single‑agent across six benchmarks (Du et al., 2023).

Before / After

Default Claude ❯ you: claude code is better than codex ⏺ claude: Noted.

⚖️ Claude with objection ❯ you: claude code is better than codex ⏺ claude: That's a claim, not an argument. Want me to cross-examine it via /objection, or are you just venting? ❯ you: /objection ⏺ claude: Objection, missing evidence. "Better" on what axis, measured how? Code quality on a benchmark, latency, cost per task, tool-use reliability? Without a metric and a number, this is preference dressed as fact.

Why this exists

Claude, by default, is collaborative. That's great for most work and terrible for pressure-testing an idea. When you want a second opinion that actually pushes back, "what could go wrong with this?" produces a polite list, not a real challenge.

objection flips the posture. Claude becomes an adversarial reviewer. Your job is to defend the claim. Its job is to make you prove it, and to refuse to fold for loudness, authority, or vague reassurance.

Usage

Trigger by phrase

Say any of the following and Claude enters objection mode:

• objection
• cross-examine this
• challenge me
• poke holes
• steelman the opposition
• devil's advocate this
• grill me

Trigger by command

On a design proposal:

/objection We should migrate the jobs queue from Redis to SQS.

On a diff or PR (code‑review mode — the skill switches automatically when it sees a diff, file path, or PR reference):

/objection review the staged changes
/objection PR #482
/objection auth/login.py — does this rate limiter actually hold under multiple workers?

End the session

Any of these render the verdict:

• I rest my case
• verdict
• end session
• that's all
• we're done

Trigger end by command

/verdict
