Deployment workflows, CI/CD pipeline patterns, Docker containerization, health checks, rollback strategies, and production readiness checklists for web applications. Use when deploying an application, setting up CI/CD, writing GitHub Actions workflows, configuring health checks, or asking about rollback strategies.
Create Mermaid diagrams (activity, deployment, sequence, architecture) from text descriptions or source code. Use when asked to "create a diagram", "generate mermaid", "document architecture", "code to diagram", "create design doc", or "convert code to diagram". Supports hierarchical on-demand guide loading, Unicode semantic symbols, and Python utilities for diagram extraction and image conversion.
Docker and Docker Compose patterns for local development, container security, networking, volume strategies, and multi-service orchestration. Use when writing a Dockerfile, setting up docker-compose, containerizing an app, or asking about container security and networking.
Deep search via Perplexity API. Three modes: search (quick facts), reason (complex analysis), research (in-depth reports). Returns AI-grounded answers with citations.
PostgreSQL database patterns for query optimization, schema design, indexing, and security. Use when designing a database schema, writing SQL queries, optimizing slow queries, adding indexes, or asking about database security and migrations.
Python development principles and decision-making. Framework selection, async patterns, type hints, project structure. Use when starting a Python project, choosing a framework, structuring code, adding type hints, or asking about Python best practices.

Fetch a PR diff via
gh, analyze it across 5 dimensions, and output a structured review report with inline findings.
/pr and wanting a self-review before requesting teammates# By PR number (current repo)

# By URL
gh pr diff <url>
# Get PR metadata

Categorize each file:

IF no PR number or URL is provided: → Ask: "Which PR should I review? Provide a number or GitHub URL."
IF gh is not authenticated:
→ Show: gh auth login instructions and stop.
IF PR has >50 changed files:
→ Focus on files in src/, app/, or core logic. Skip lock files, generated files, assets.
IF security issue found (severity: CRITICAL):
→ Flag at top of report with 🚨 CRITICAL before any other findings.
IF no tests changed but logic files changed: → Always flag as a finding under Test Coverage: "No tests added/modified for changed logic."
DEFAULT: → Run all 5 dimensions, produce full report.
## PR Review: <title> (#<number>)
**Branch**: `<head>` → `<base>`
**Changes**: +<additions> / -<deletions> across <N> files
---
### 🚨 Critical Issues
(Security or correctness blockers — must fix before merge)
- `path/to/file.py:42` — **Hardcoded API key** `SECRET_KEY = "abc123"`. Move to env var.
---
### ⚠️ Warnings
(Should fix — code quality, missing tests, non-critical bugs)
- `path/to/file.py:17` — **Mutable default argument** `def process(items=[])`. Use `None` and assign inside.
- `path/to/service.py` — **No tests added** for new `PaymentService.charge()` method.
---
### 💡 Suggestions
(Nice to have — style, naming, minor improvements)
- `path/to/utils.py:88` — Function `do_stuff()` is 73 lines. Consider splitting.
- `path/to/models.py:12` — Magic number `86400`. Extract as `SECONDS_IN_DAY = 86400`.
---
### ✅ Looks Good
- Test coverage added for happy path and edge cases
- Type hints present on all public functions
- No secrets detected
