Your task

**CRITICAL: This command leverages 8-10 parallel sub-agents for instant comprehensive PR analysis, achieving 8-10x faster reviews than sequential analysis.**

STEP 1: Initialize PR review session

CREATE session state: `/tmp/pr-review-state-$SESSION_ID.json`
INITIALIZE review session with timestamp and context
PARSE arguments from $ARGUMENTS for action and PR number
SET session data:

  {
    "sessionId": "$SESSION_ID",
    "timestamp": "ISO_8601_TIMESTAMP",
    "action": "auto-detect",
    "prNumber": null,
    "repository": "auto-detect",
    "reviewPhase": "initialization",
    "analysisResults": {},
    "parallelAgentResults": {},
    "reviewDecisions": [],
    "errorLog": []
  }

STEP 2: Parse arguments and determine review action

IF $ARGUMENTS is empty:

SET action = "discover_prs"
FOCUS on PRs assigned for review and current branch PR

EXTRACT action and optional PR number
SET review_action = detected action

ELSE IF $ARGUMENTS is numeric:

SET prNumber = $ARGUMENTS
SET action = "review_specific_pr"

ELSE:

LOG invalid arguments to session state
PROVIDE usage examples and available PRs

STEP 3: Execute PR discovery or direct review

CASE action: WHEN "discover_prs":

TRY:

FETCH PRs assigned for review: `gh pr list --search "review-requested:@me" --json number,title,author,createdAt`
FETCH current branch PR: `gh pr list --head $(git branch --show-current) --json number,title,state`
FETCH mentioned PRs: `gh pr list --search "mentions:@me" --json number,title,state`
DISPLAY interactive PR selection with priorities:

1. PRs explicitly assigned for review (highest priority) 2. Current branch PR (if exists) 3. PRs where mentioned (lowest priority)

SAVE PR list to session state

WHEN "review_specific_pr":

VALIDATE PR number exists and is accessible
PROCEED to comprehensive PR analysis

CATCH (github_api_error):

LOG API errors to session state
CHECK GitHub authentication status
PROVIDE troubleshooting guidance
FALLBACK to manual PR specification

STEP 4: Ultra-Fast Parallel PR Analysis

**CRITICAL: IMMEDIATELY DEPLOY 8-10 PARALLEL SUB-AGENTS for instant comprehensive PR review. NO SEQUENTIAL ANALYSIS.**

TRY:

FETCH PR metadata: `gh pr view $PR_NUMBER --json title,body,state,author,assignees,labels,milestone,files,changedFiles,additions,deletions`
SAVE PR metadata to: `/tmp/pr-review-$SESSION_ID/pr-metadata.json`

**LAUNCH ALL 8-10 AGENTS SIMULTANEOUSLY IN A SINGLE RESPONSE:**

1. **Code Quality & Architecture Agent**

ANALYZE: Design patterns, SOLID principles, code smells, cyclomatic complexity
SCAN: Architecture violations, coupling issues, abstraction levels
OUTPUT: `/tmp/pr-review-$SESSION_ID/code-quality.json`
FOCUS: "Review PR #$PR_NUMBER for code quality, design patterns, and architectural concerns"

2. **Security Vulnerability Agent**

SCAN: OWASP Top 10 patterns, credential exposure, injection vulnerabilities
CHECK: Authentication/authorization flaws, cryptographic issues
OUTPUT: `/tmp/pr-review-$SESSION_ID/security-analysis.json`
FOCUS: "Perform security audit of PR #$PR_NUMBER for vulnerabilities and exposed secrets"

3. **Performance & Scalability Agent**

IDENTIFY: N+1 queries, memory leaks, inefficient algorithms
ANALYZE: Bundle size impact, database query optimization
OUTPUT: `/tmp/pr-review-$SESSION_ID/performance-impact.json`
FOCUS: "Assess performance implications of PR #$PR_NUMBER including algorithmic complexity"

4. **Test Coverage & Quality Agent**
