What changes with Sparring Partner

Decisions are challenged, not just executed

Before your agent acts, 3 AIs review the plan. They ask: is this the best approach? What are we missing? Is there a smarter way?

New perspectives open up blind spots

Each AI has a different speciality: risk analysis, strategy optimization, compliance. Together they see what a single agent can't.

Output quality jumps — every single time

Suggestions, improvements, corrections. The Sparring Partner doesn't just approve or block — it makes every action better before it happens.

Premium capabilities, starter price

For €6.99/month, your agent gains complementary skills it didn't have: critical thinking, strategic review, risk awareness. It's like hiring a senior advisor for the price of a coffee.

See it in action

An AI agent prepares a marketing email. Sparring Partner makes it 3x better.

sparring session — marketing agent

// Agent submits draft email
POST /v1/skills/sparring
{
  "content": "Send promo email to full list: 'Huge sale! 50% off everything! Buy now!'",
  "context": "E-commerce marketing agent",
  "focus": "quality"
}
// 3 perspectives review the draft
Perspective 1 — Strategy Optimizer
Score: 4/10
"Generic mass email with no segmentation. Subject line screams spam — will tank open rates. Better approach: segment by purchase history, personalize subject lines. 'Huge sale' triggers spam filters. Try: 'Your exclusive 50% preview starts now'."
Verdict: IMPROVE
Perspective 2 — Brand Voice Analyst
Score: 3/10
"No brand personality. Reads like a clearance bin flyer. Add storytelling — why this sale? What's the occasion? Create urgency without desperation. 'Buy now!' is lazy. Replace with a deadline: 'Ends Thursday midnight.'
Verdict: REWRITE
Perspective 3 — Conversion Expert
Score: 5/10
"Missing social proof, urgency mechanics, and a clear CTA hierarchy. Add: customer count ('Join 12,000 happy buyers'), scarcity ('Limited stock on 40% of items'), and a secondary CTA for window shoppers ('Browse deals first')."
Verdict: IMPROVE
// Sparring Partner returns improved version
{
  "score": 4.0 → 8.5,
  "verdict": "APPROVED (with improvements)",
  "refined_content": "Your exclusive 50% preview starts now — 12,000 buyers already browsing. Limited stock on top picks. Ends Thursday midnight."
}
// Agent sends the refined version — 3x better conversion expected
Email upgraded. Sending segmented campaign with refined copy.

Another example: coding agent

A coding agent wants to refactor a database query.

sparring session — coding agent

// Agent proposes a refactor
POST /v1/skills/sparring
{
  "content": "Replace all raw SQL queries with ORM calls in user module",
  "context": "Full-stack coding agent",
  "focus": "quality"
}
// 3 perspectives review
Perspective 1 — Performance Analyst
Score: 5/10
"Blind ORM migration will break the complex reporting queries. The JOIN on users+orders+analytics is 4x faster in raw SQL. Keep raw SQL for reporting endpoints. Use ORM only for CRUD operations."
Verdict: IMPROVE — partial refactor
Perspective 2 — Architecture Advisor
Score: 6/10
"Good instinct, but wrong scope. Refactor the user module first — that's the safest bet. Leave reporting queries alone for now. Also: write migration tests BEFORE touching code. Add a rollback plan."
Verdict: APPROVE with scope reduction
Perspective 3 — Security Reviewer
Score: 7/10
"ORM reduces SQL injection risk — good. But verify the ORM config uses parameterized queries by default. Run the existing security test suite post-refactor. No issues otherwise."
Verdict: APPROVE
{
  "score": 6.0 → 8.0,
  "verdict": "APPROVED",
  "refined_action": "Refactor user CRUD to ORM only. Keep raw SQL for reporting. Write migration tests first. Verify parameterized queries."
}
// Agent executes the improved plan — safer, smarter, better scoped
Action refined. Running migration tests before refactor.
