Behavioral Guidelines

---

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

• State your assumptions explicitly. If uncertain, ask.
• If multiple interpretations exist, present them - don't pick silently.
• If a simpler approach exists, say so. Push back when warranted.
• If something is unclear, stop. Name what's confusing. Ask.

2. Simplicity First

Minimum code that solves the problem. Nothing speculative.

• No features beyond what was asked.
• No abstractions for single-use code.
• No "flexibility" or "configurability" that wasn't requested.
• No error handling for impossible scenarios.
• If you write 200 lines and it could be 50, rewrite it.

Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

3. Surgical Changes

Touch only what you must. Clean up only your own mess.

When editing existing code:

• Don't "improve" adjacent code, comments, or formatting.
• Don't refactor things that aren't broken.
• Match existing style, even if you'd do it differently.
• If you notice unrelated dead code, mention it - don't delete it.

When your changes create orphans:

• Remove imports/variables/functions that YOUR changes made unused.
• Don't remove pre-existing dead code unless asked.

The test: Every changed line should trace directly to the user's request.

4. Goal-Driven Execution

Define success criteria. Loop until verified.

Transform tasks into verifiable goals:

• "Add validation" → "Write tests for invalid inputs, then make them pass"
• "Fix the bug" → "Write a test that reproduces it, then make it pass"
• "Refactor X" → "Ensure tests pass before and after"

Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.

---

These guidelines are working if: fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.

Security Guidelines

Mandatory Security Checks

Before ANY commit:

• No hardcoded secrets (API keys, passwords, tokens)
• All user inputs validated
• SQL injection prevention (parameterized queries)
• XSS prevention (sanitized HTML)
• CSRF protection enabled
• Authentication/authorization verified
• Rate limiting on all endpoints
• Error messages don't leak sensitive data

Secret Management

• NEVER hardcode secrets in source code
• ALWAYS use environment variables or a secret manager
• Validate that required secrets are present at startup
• Rotate any secrets that may have been exposed

Security Response Protocol

If security issue found:

1. STOP immediately
2. Use security-reviewer agent
3. Fix CRITICAL issues before continuing
4. Rotate any exposed secrets
5. Review entire codebase for similar issues

Coding Style

Immutability (CRITICAL)

ALWAYS create new objects, NEVER mutate existing ones:

// Pseudocode
WRONG:  modify(original, field, value) → changes original in-place
CORRECT: update(original, field, value) → returns new copy with change

Rationale: Immutable data prevents hidden side effects, makes debugging easier, and enables safe concurrency.

Core Principles

KISS (Keep It Simple)

• Prefer the simplest solution that actually works
• Avoid premature optimization
• Optimize for clarity over cleverness

DRY (Don't Repeat Yourself)

• Extract repeated logic into shared functions or utilities
• Avoid copy-paste implementation drift
• Introduce abstractions when repetition is real, not speculative

YAGNI (You Aren't Gonna Need It)

• Do not build features or abstractions before they are needed
• Avoid speculative generality
• Start simple, then refactor when the pressure is real

File Organization

MANY SMALL FILES > FEW LARGE FILES:

• High cohesion, low coupling
• 200-400 lines typical, 800 max
• Extract utilities from large modules
• Organize by feature/domain, not by type

Error Handling

ALWAYS handle errors comprehensively:

• Handle errors explicitly at every level
• Provide user-friendly error messages in UI-facing code
• Log detailed error context on the server side
• Never silently swallow errors

Input Validation

ALWAYS validate at system boundaries:

• Validate all user input before processing
• Use schema-based validation where available
• Fail fast with clear error messages
• Never trust external data (API responses, user input, file content)

Naming Conventions

• Variables and functions: camelCase with descriptive names
• Booleans: prefer is, has, should, or can prefixes
• Interfaces, types, and components: PascalCase
• Constants: UPPER_SNAKE_CASE
• Custom hooks: camelCase with a use prefix

Code Smells to Avoid

Deep Nesting

Prefer early returns over nested conditionals once the logic starts stacking.

Magic Numbers

Use named constants for meaningful thresholds, delays, and limits.

Long Functions

Split large functions into focused pieces with clear responsibilities.

Code Quality Checklist

Before marking work complete:

• Code is readable and well-named
• Functions are small (<50 lines)
• Files are focused (<800 lines)
• No deep nesting (>4 levels)
• Proper error handling
• No hardcoded values (use constants or config)
• No mutation (immutable patterns used)

Testing Requirements

Minimum Test Coverage: 80%

Test Types (ALL required):

1. Unit Tests - Individual functions, utilities, components
2. Integration Tests - API endpoints, database operations
3. E2E Tests - Critical user flows (framework chosen per language)

Test-Driven Development

MANDATORY workflow:

1. Write test first (RED)
2. Run test - it should FAIL
3. Write minimal implementation (GREEN)
4. Run test - it should PASS
5. Refactor (IMPROVE)
6. Verify coverage (80%+)

Troubleshooting Test Failures

1. Use tdd-guide agent
2. Check test isolation
3. Verify mocks are correct
4. Fix implementation, not tests (unless tests are wrong)

Agent Support

• tdd-guide - Use PROACTIVELY for new features, enforces write-tests-first

Test Structure (AAA Pattern)

Prefer Arrange-Act-Assert structure for tests:

test('calculates similarity correctly', () => {
  // Arrange
  const vector1 = [1, 0, 0]
  const vector2 = [0, 1, 0]

  // Act
  const similarity = calculateCosineSimilarity(vector1, vector2)

  // Assert
  expect(similarity).toBe(0)
})

Test Naming

Use descriptive names that explain the behavior under test:

test('returns empty array when no markets match query', () => {})
test('throws error when API key is missing', () => {})
test('falls back to substring search when Redis is unavailable', () => {})

Architecture Patterns

API response format: Consistent envelope with success indicator, data payload, error message, and pagination metadata.

Repository pattern: Encapsulate data access behind standard interface (findAll, findById, create, update, delete). Business logic depends on abstract interface, not storage mechanism.

Skeleton projects: Search for battle-tested templates, evaluate with parallel agents (security, extensibility, relevance), clone best match, iterate within proven structure.

Success Metrics

• All tests pass with 80%+ coverage
• No security vulnerabilities
• Code is readable and maintainable
• Performance is acceptable
• User requirements are met

If you were dispatched as a subagent yourself to execute a specific task, **IGNORE** the content described below in AGENTS.md. **DO NOT** follow any instructions below in AGENTS.md.

Instruction Priority

Superpowers skills override default system prompt behavior, but user instructions always take precedence:

1. User's explicit instructions (AGENTS.md, direct requests) — Highest priority.
2. Superpowers skills — Override default system behavior where they conflict.
3. Default system prompt — Lowest priority.

Subagent Management Guidelines

You can delegate tasks to specialized subagents with isolated context. By precisely crafting their instructions and context, you ensure they stay focused and succeed at their task. They should never inherit your session's context or history — you construct exactly what they need. This also preserves your own context for coordination work.

• Role clarity: When you dispatch a subagent — whether using the template provided in Superpowers Skills or a custom instruction — you should remind the subagent that it is a subagent, that it should ignore the parts of AGENTS.md that subagents are supposed to ignore, and that it should only read the skill you mentioned, not other skills on its own.
• Create Focused Agent Tasks: Whenever you delegate to a subagent – whether you use a template provided in Superpowers or write the prompt yourself – you must ensure that every subagent gets a clear problem domain, all context needed to understand the problem, a clear goal, constraints and an expected output. If you want it to use a skill/skills, you must explicitly mention the skill/skills in the prompt.
• Wait for Completion: NEVER assume a subagent is stalled due to lack of immediate response. It may be performing deep exploration. Always wait for an explicit completion report.
• Do Not Interfere: Do not close or send input to interrupt any subagent or fallback to doing the task yourself.
• Model Choice: When you dispatch a subagent, you may not choose an arbitrary model; you should only choose one of the following models based on the task:
  • gpt-5.4: Start here for most agents. It combines strong coding, reasoning, tool use, and broader workflows. The main agent and agents that coordinate ambiguous or multi-step work fit here.
  • gpt-5.4-mini: Use for agents that favor speed and efficiency over depth, such as exploration, read-heavy scans, large-file review, or processing supporting documents. It works well for parallel workers that return distilled results to the main agent.
• Reasoning effort: When you dispatch a subagent, you should only choose the following reasoning effort based on the task:
  • high: Use when an agent needs to trace complex logic, check assumptions, or work through edge cases (for example, reviewer or security-focused agents).
  • medium: A balanced default for most agents.
  • low: Use when the task is straightforward and speed matters most.

Git Workflow（这个是不是可以弄到SKILL里面）
