sniper-check

Sniper Check runs the full sniper agent 6-phase code-quality workflow (parallel explore-codebase + research-expert, Grep-based impact analysis, linter error detection, minimal correction, re-verification to zero errors) in an isolated forked context, so only the final validation report returns to the parent conversation -- nothing of the investigation itself pollutes it. Use it after any code modification, on a specific file, a directory, or the whole project.

Sniper Check

Overview

Quick code quality validation using the sniper agent in an isolated forked context. Executes the full 6-phase workflow without polluting the main conversation context.

Feature	Detail
Context	Forked (isolated sub-agent)
Agent	sniper (Sonnet)
Phases	6-phase code-quality workflow
Result	Only final report returns to parent

When to Use

Scenario	Use
After code modifications	/sniper-check src/
Validate specific file	/sniper-check path/to/file.ts
Full project check	/sniper-check .
After refactoring	/sniper-check src/components/

Workflow

Execute the mandatory 6-phase code-quality workflow:

1. PHASE 1+2 (PARALLEL): Launch both in parallel:
   • explore-codebase (Haiku) → Architecture discovery
   • research-expert (Sonnet) → Documentation verification
2. PHASE 3: Grep all usages → Impact analysis
3. PHASE 4: Run linters → Detect errors
4. PHASE 5: Apply corrections → Minimal changes
5. PHASE 6: Re-run linters → Zero errors

CRITICAL: Phases 1+2 must run in PARALLEL (two Task calls in one message).

Critical Rules

Rule	Reason
Never skip phases 1+2	Documentation-backed fixes only
Always run phases in order	Dependencies between phases
Zero linter errors	Non-negotiable exit criteria
Minimal changes only	Smallest fix necessary

---

Report Format

Return a validation report with:

• Architecture summary (from explore-codebase)
• Documentation references (from research-expert)
• Impact analysis table (usages, risk level)
• Errors fixed (critical, high, medium, low)
• SOLID compliance status
• Final linter status (must be ZERO errors)
