Review
Review the requested Python scope with these priorities.
Input
Scope: $ARGUMENTS
Review Dimensions
- Correctness and boundary safety — external data validated at boundaries; no raw payloads in typed core
- Design clarity and maintainability — clear module responsibilities; SOLID applied
- Test quality and debugging ergonomics — behavioral names; AAA pattern; edge cases covered
- Type health and escape hatches — no unjustified
Any; boundary modules only for raw data - Operational clarity — clear failures; explicit configuration; debuggable behavior
Checklist
TYPE SAFETY
- [ ] All functions have complete type hints
- [ ] No Any outside boundary modules
- [ ] No legacy typing imports (List, Dict, Optional, Union)
ERROR HANDLING
- [ ] No bare except clauses
- [ ] No swallowed exceptions
- [ ] Exceptions have context (add_note or from)
SECURITY
- [ ] No SQL injection vulnerabilities
- [ ] No command injection (shell=True with user input)
- [ ] No hardcoded secrets
- [ ] Input validation present at boundaries
DESIGN
- [ ] Functions under 50 lines
- [ ] No deep nesting (>3 levels)
- [ ] No circular imports
- [ ] __all__ defined in public modules
- [ ] SOLID principles followed
TESTING
- [ ] Tests exist for changed code
- [ ] Edge cases covered
- [ ] pytest-mock (not unittest.mock)
BOUNDARY
- [ ] Raw data validated before crossing into typed core
- [ ] Boundary modules use approved naming (parse_*, validate_*, etc.)
- [ ] Typed return values from boundary code

Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
ccc
This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the index', 'ccc', 'cocoindex-code'.
agent-browser
Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.
delegate
Quick delegation template for sub-agent prompts. Use when assigning work to a sub-agent, before invoking the Agent tool, or when preparing prompts for specialized agents. Provides the WHERE-WHAT-WHY framework. For comprehensive delegation guidance, activate the agent-orchestration how-to-delegate skill.
swarm-spawning
Spawn agents and teammates in Claude Code swarms. Use when choosing between subagents vs teammates, selecting agent types (Explore, Plan, general-purpose, plugin agents), configuring spawn backends (in-process, tmux, iterm2), or setting environment variables for spawned agents.
knowledge-explorer
Manage the research/ knowledge base (KB) of tool and library research entries. Use when browsing KB topics, adding new research entries, updating existing entries with dated revisions, fetching GitHub repo metadata into a draft KB entry, or migrating old-format entries to skill-spec frontmatter. Triggers on tasks like "what do we have on X", "add this to the KB", "update the KB entry for Y", "fetch github info for owner/repo", or "migrate old entries".
design-anti-patterns
Enforce anti-AI UI design rules based on the Uncodixfy methodology. Use when generating HTML, CSS, React, Vue, Svelte, or any frontend UI code. Prevents "Codex UI" — the generic AI aesthetic of soft gradients, floating panels, oversized rounded corners, glassmorphism, hero sections in dashboards, and decorative copy. Applies constraints from Linear/Raycast/Stripe/GitHub design philosophy: functional, honest, human-designed interfaces. Triggers on: UI generation, dashboard building, frontend component creation, CSS styling, landing page design, or any task producing visual interface code.
