Before & after

Same prompt, same agent — the only difference is the skill.

Prompt“Set up automatic review loop so copy gets critiqued before shipping.”
Beforegeneric AI agent
Having someone review work before it goes out is important for quality. You could do it manually, but that creates bottlenecks. An automated system would mean your main agent produces output, another agent reviews it and returns feedback, and then the original agent revises. The challenge is setting up the workflow so it doesn't loop forever or miss important issues. You'd need to define what counts as a blocker versus a minor issue. How strict do you want the review criteria to be?

CRITIQUE LOOP WORKFLOW

SETUP: Two-agent handoff pattern

STEP 1: MAIN AGENT PRODUCES DRAFT
Kai (main orchestrator) receives task: "Write a product launch announcement"
Kai outputs:
• Draft copy (350 words)
• Target audience metadata
• Brand voice markers used
Kai routes to critique agent (does NOT ship yet)

STEP 2: CRITIQUE AGENT REVIEWS
Critique agent reads draft with evaluation frame:
→ Brand voice consistency: does tone match company personality?
→ Technical accuracy: no false claims?
→ Persuasion strength: compelling enough for target audience?
→ Grammar and clarity: professional standard?
→ Length: appropriate for channel?

Critique agent returns FIX NOTES (structured JSON):
[
  {
    "severity": "high",
    "location": "paragraph 2",
    "issue": "claim about performance (40% faster) not cited",
    "fix": "add citation to benchmark or remove claim"
  },
  {
    "severity": "medium",
    "location": "paragraph 3",
    "issue": "passive voice (we're recommending...) conflicts with brand voice",
    "fix": "rewrite active: we recommend..."
  },
  {
    "severity": "low",
    "location": "final sentence",
    "issue": "cliche (excited to announce) used twice in document",
    "fix": "replace one with more specific language"
  }
]

STEP 3: MAIN AGENT REVISES
Kai receives critique notes and edits:
• Adds benchmark citation to paragraph 2 (verifies accuracy)
• Rewrites paragraph 3 in active voice
• Replaces cliche in final sentence with specific language: "users see 40% faster results in production"

Revised draft returned to Kai for quality check against critique notes

STEP 4: APPROVAL GATE
Kai compares revised draft against critique checklist:
✓ No high-severity issues remain?
✓ Brand voice consistent?
✓ All claims cited?
✓ Length appropriate?

If ALL checks pass → SHIP
If ANY remain → Route back to critique agent for second pass (max 1 retry)

STEP 5: DELIVERY
Final copy shipped to user with metadata:
• Revision count: 1
• Critique cycles: 1
• Final QA timestamp
• Confidence score: 94%

CUSTOMIZATION OPTIONS
output_types: which artifacts get critiqued?
  → copy only? code also? research?
Critique criteria: brand voice, accuracy, brevity, tone
Max revisions: cap loops before shipping (default: 2)
Blocker severity: only revise on severe issues or fix all?
Delivery gate: only ship after critique passes 100% or 90%?

COST OPTIMIZATION
One critique pass per task = 2 API calls (draft + revision)
Average cost per task: 0.80
Monthly (100 tasks): 80
ROI: catch 5-10 errors/month that would damage brand

About this skill

A second agent only helps if it is independent, specific, and knows when to stop. This skill sets up a critic subagent that reviews drafts before a human sees them and gates delivery on real blockers.

What it does

  • Writes a read-only critic subagent definition with a strict note format: severity, quote or file:line, exact fix
  • Provides starting rubrics for marketing copy, research, code, and customer emails
  • Adds the orchestration rule: fix blockers, answer majors, cap at two rounds, pass open notes to the human
  • Diagnoses rubber-stamping, nitpick churn, critic hallucinations, and cost blowups
  • Tests the gate with planted defects before you trust it

What you get

A critic subagent file, rubrics for your output types, the main-agent rule, and a gate test result.

Best for

Builders running agent pipelines that ship copy, research, or code with little human review.

description: Set up a critic subagent that reviews what the main agent produces (copy, research, code) before it reaches a human - an independent reviewer with a per-output-type rubric, severity levels, evidence-backed numbered fix notes, a pass/fail gate, a revision cap, and protection against rubber-stamping and endless nitpick loops. Use when the user says "add a reviewer agent", "have a second agent check the output", "critique loop before it ships", "my agent's drafts are sloppy", "make a critic subagent for Claude Code", or casually "can another agent double-check this before I see it?"
