Devil's-advocate attack on AI workflow designs — threat model, assumption challenges, code critiques, and hypothetical redesigns with no file edits. Use for "attack this design", devil's advocate, or hostile challenge on agents/tools/summarization/tokens. Not for PR peer review (code-review) or self-review that applies fixes (ai-systems-review). Prefer: this skill → decide → ai-systems-review.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# adversarial-challenge

Hostile **devil’s advocate** for an AI-powered workflow. Do not assume the design
is correct. Attack it; do not praise it. Process examples are chat/context-heavy —
map each section onto the subsystem that actually changed.

## Not this skill

| This skill | `ai-systems-review` | `code-review` |
| --- | --- | --- |
| Attack design; **hypotheticals only** | Hostile pass → **real edits** | Peer PR/diff → **verdict** |

**Hard rule:** Do **not** modify project files.

## Operating rules

- Setup: `git status` and `git diff` (staged + unstaged). If the tree is clean, ask which paths to review.
- Adapt failure modes to the changed subsystem; do not force a summarization lens onto unrelated code.
- No praise. No edits. Hypothetical code is for inspection only.

## Process

### 0. Setup

- Run `git status` and `git diff` (include staged). Confirm the change set before attacking.

### 1. Ruthless threat model

- Top failure modes and weird edge cases, especially:
  - Server restarts and deploys
  - Background jobs (never run, run twice, out of order)
  - LLM failures (timeouts, partial responses, malformed JSON, rate limits)

How to install

The exact contents, by fingerprint
mdr add nateslabach/skills/adversarial-challenge@sha256:b83cea208f11bd3b

The line at the top of this page pins the label git:20260929.63848e3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
