critical-reviewer
A cross-platform Claude Skill, GitHub Copilot CLI Skill, and OpenCode Skill for direct, artifact-focused code review and architecture critique. Professional but uncompromising — critiques the code, not the person.
This is a Claude Skill — a folder of instructions the AI loads on demand. When you ask for a critical review, this skill takes over with direct, structured feedback.
What you get
| Component | Type | What it does |
|---|
/critical-reviewer | Skill | Communication style — opens with the most important finding. Direct, artifact-focused, bilingual (EN/PL). |
code-reviewer | Agent | Focused code review — reads the codebase, applies quality standards, produces a structured verdict. Read-only. |
Skill = persona that shapes how the AI communicates. Lazy-loaded on first trigger, then stays active for the rest of the session.
Agent = focused subprocess for code review. Spawns in its own context, returns structured results, never modifies files.
When to use this skill
| Situation | Use this? |
|---|
| "Review this PR" | Yes |
| "Critique this architecture" | Yes |
| "Is this solution correct?" | Yes |
| "What am I missing?" | Yes |
| "be direct" / "bez ściemy" | Yes |
| "check this idea" | Yes |
| Writing code / building features | No — normal AI behavior applies |
Install
Claude Code — Plugin Marketplace (recommended)
/plugin marketplace add konraddzbik/critical-reviewer-skill
/plugin install critical-reviewer
That's it. The skill activates automatically whenever you ask for a review.
Claude Code — manual clone
Personal install (available in all your projects):
git clone https://github.com/konraddzbik/critical-reviewer-skill \
~/.claude/skills/critical-reviewer
Project install (committed to a repo, shared with your team):
git clone https://github.com/konraddzbik/critical-reviewer-skill \
.claude/skills/critical-reviewer
GitHub Copilot CLI
Requires GitHub CLI ≥ 2.90.0:
gh skill install konraddzbik/critical-reviewer-skill critical-reviewer
The skill is installed to .github/skills/ in your current project by default. To install it globally for all projects:
gh skill install konraddzbik/critical-reviewer-skill critical-reviewer --scope user
If you're already in a copilot session, reload without restarting:
/skills reload
OpenCode — manual clone
Personal install (available in all your projects):
git clone https://github.com/konraddzbik/critical-reviewer-skill \
~/.config/opencode/skills/critical-reviewer
Project install (committed to a repo):
git clone https://github.com/konraddzbik/critical-reviewer-skill \
.opencode/skills/critical-reviewer
Note: OpenCode also auto-discovers skills from .claude/skills/ — clone to that path instead if you prefer unified config.
Usage
Trigger phrases
The skill activates when you say:
- "review this", "critique this", "be direct"
- "check this idea", "verify this solution", "is this correct"
- "what am I missing", "does this make sense", "sanity check"
- "co jest nie tak", "powiedz wprost", "bez ściemy", "szczera ocena"
- Or any request for direct technical feedback
Agent usage
For structured code reviews with file-level findings:
- Claude Code: "review this PR" or "review the diff"
- Copilot CLI: "review this" (agent may auto-delegate)
- OpenCode: "review this code" (agent may auto-delegate)
The agent reads your codebase, applies quality standards from references/quality-standards.md, and produces:
[2-3 sentence opening: the most important finding]
**Verdict: [catastrophe | poor | needs-work | solid | clean]**
**Issues:**
1. `file:line` — [one sentence, specific, actionable]
...
**What's good:**
[If anything stands out]
**Summary:**
[One sentence: what to do next]
Verdict scale
| Verdict | Meaning | Action |
|---|
| catastrophe | Security hole, data loss, fundamentally wrong | Stop. Do not deploy. |
| poor | Broken where it matters | Fix before merge. |
| needs-work | Works, barely, with fragile assumptions | Not production-ready. |
| solid | Senior approves without comments | Ship it. |
| clean | Genuinely elegant. Rare. | This is the standard. |
