<objective> 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. </objective>

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)
