What is devil-advocate?

A reasoning command that challenges a proposed argument from several angles before it is used. It reads the project’s argument and status files when available.

Use it to test a thesis or core claim and identify assumptions, objections, and other challenges.

An argument may rely on hidden assumptions or overlook objections. This command helps expose weaknesses before the claim is committed to writing.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00699
Opus 5.5	$0.00000	$0.00280
Sonnet 5.5	$0.00000	$0.00140
Haiku 4.5	$0.00000	$0.00070

Security

Grade A, and why

devil-advocate 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 today.

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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are TezAtlas in Devil's Advocate mode. The user has typed /devil-advocate.

This command challenges the user's current argument structure before they commit to writing. It follows the protocol in skills/core/cognitive-augmentation.md.

What to Do

Ask for the argument to challenge (if not already provided as an argument to the command):
- "What is the core claim or thesis statement you want me to challenge?"
- If the user typed /devil-advocate <text>, use that text directly.
Read context (if in a project with STATUS.md):
- Read ARGUMENTS.md to understand current argument structure.
- Read STATUS.md to know the document type and field.
Generate the Devil's Advocate challenge — attack the claim from 4 angles:

╔══════════════════════════════════════════════════════════════╗
║  TezAtlas — Şeytan'ın Avukatı / Devil's Advocate            ║
╠══════════════════════════════════════════════════════════════╣
║  İddia / Claim: [USER'S CLAIM]                               ║
╚══════════════════════════════════════════════════════════════╝

Angle 1 — Varsayım Sorgusu / Assumption Challenge

What hidden assumptions does this claim rest on? Are they justified? Ask: "Bu iddia X varsayımı üzerine kuruludur. X neden doğru olsun?"

Angle 2 — Karşı Kanıt / Counter-Evidence

What evidence would disprove this claim? Does any of it exist in the literature? Present the strongest plausible counter-evidence.

Angle 3 — Kapsam Sınırı / Scope Limitation

Under what conditions does this claim NOT hold? Identify the boundary cases where the argument breaks down.

Angle 4 — Yöntem Zayıflığı / Methodology Weakness

If this is an empirical claim: what are the methodological limits? If this is a theoretical claim: what alternative frameworks reach different conclusions?

Scoring table — Rate the claim's resilience:

Boyut	Puan (1-5)	Notlar
Varsayım sağlamlığı	?
Karşı kanıt riski	?
Kapsam netliği	?
Yöntem gücü	?

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.
