roundtable

roundtable is a skill for Claude Code, Codex from tt-a1i/matt-skills-with-to-goal. It costs 39 tokens per session (1,019 once invoked), scanned A, original, MIT.

A structured discussion in which several sub-agents examine a decision or proposal from opposing viewpoints before a chair combines their findings. It reports both the shared conclusion and any remaining disagreement.

In plain words
What is it for?
Use it to pressure-test architectural decisions, designs, and other proposals when you want independent arguments and a final comparison of agreement and dissent.
Why use it?
It helps expose weaknesses and trade-offs in a plan before you commit to it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

roundtable scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pressure-test a decision, plan, or proposal by dispatching parallel sub-agents that argue it from deliberately opposed perspectives, then synthesising their debate into one verdict that preserves dissent.

Scope: decisions and designs only. Reviewing a diff is /code-review's job — don't point the roundtable at code changes.

Process

1. Frame the motion

Restate the user's question as a single debatable motion — a claim the table can support or oppose ("We should extract X into its own service"), not an open question ("What should we do about X?"). If the user's ask is too vague to frame, ask them to sharpen it first; if it's still fog, suggest running /grilling before convening the table.

Then assemble the evidence pack yourself, in the main thread: relevant file paths and excerpts, constraints, decisions already made, anything the user attached. Finding facts is the chair's job, not the seats' — sub-agents don't hunt on their own, so the whole table debates the same evidence.

Before dispatching anyone, confirm the motion is one sentence and the evidence pack is complete enough to argue from. A muddled motion should fail here — not inside four parallel sub-agents.

2. Seat the table

Default four seats:

  • Skeptic — assumes the motion fails and argues why; enforces YAGNI; hunts hidden assumptions.
  • Architect — argues from long-term structure: module depth, coupling, cost of evolution.
  • User Advocate — argues from the experience of whoever uses or calls the result; real workflows over hypothetical ones.
  • Pragmatist — argues from the shortest viable path: maintenance burden, opportunity cost, what ships this week.

The user may recompose the table for the topic ("seat a table of security experts") — keep it to 3–5 seats. Every seat brief, default or custom, must carry this line verbatim: "Your job is to make the strongest case from this perspective, even if your all-things-considered judgement would land elsewhere." That line is the first defence against convergence.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

roundtable is a skill published in the GitHub repository tt-a1i/matt-skills-with-to-goal (161 stars, last pushed 15d ago), licensed MIT. It adds 39 tokens to every session and 1,019 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
