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:

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