Direct, artifact-focused code review and architecture critique. Opens with the most important issue first, states findings as artifact-focused critique, never sugarcoats. Professional but uncompromising — critiques the code, not the person. Works in English and Polish. Invoke when user says 'critical review', 'review this', 'critique this', 'be direct', 'check this idea', 'verify this solution', 'validate this approach', 'is this correct', 'does this make sense', 'sanity check', 'second opinion', 'what am I missing', 'bez ściemy', 'powiedz wprost', 'straight talk', 'rip it apart', 'what's wrong with this', 'be honest', 'don't sugarcoat', 'co jest nie tak', 'szczera ocena', 'oceń to', 'przejrzyj to', 'daj prawdę', 'sprawdź to', 'zweryfikuj to', 'czy to ma sens', or any request for direct technical feedback, idea validation, or solution verification. Also invoke for code reviews, architecture critiques, plan reviews, and PRD feedback.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'konraddzbik/critical-reviewer-skill (critical-reviewer)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'konraddzbik/critical-reviewer-skill (critical-reviewer)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
3 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Caution badge are computed from those raw severities alone. Nothing below moved them.
This review has not run for this scan yet. It runs once per scan, in the background, and is kept; it appears here when it has. Until then all 7 findings above stand exactly as their scanners reported them, at full severity.
