426 | 3. **Publish to NPM**: Automatically publish if version has changed
427 | 4. **Create Release**: Generate GitHub release with version tag
428 |
429 | ### Manual Version Management
430 |
431 | ```bash
432 | # Bump patch version (1.0.0 -> 1.0.1)
433 | pnpm run release:patch
434 |
435 | # Bump minor version (1.0.0 -> 1.1.0)
436 | pnpm run release:minor
437 |
438 | # Bump major version (1.0.0 -> 2.0.0)
439 | pnpm run release:major
440 | ```
441 |
442 | ### Setting up NPM Token
443 |
444 | To enable automatic deployment, add your NPM token to GitHub Secrets:
445 |
446 | 1. Go to [npmjs.com](https://www.npmjs.com) and create an automation token
447 | 2. In your GitHub repository, go to Settings > Secrets and variables > Actions
448 | 3. Add a new secret named `NPM_TOKEN` with your NPM token value

/src/resources/policies/access-control.md:
--------------------------------------------------------------------------------
```markdown
1 | # Access Control Policy
2 |
3 | ## Principles
4 |
5 | ### Least Privilege
6 | - Users granted minimum permissions necessary
7 | - Permissions reviewed regularly
8 | - Temporary elevated access logged and time-limited
9 |
10 | ### Separation of Duties
11 | - Critical operations require multiple approvals
12 | - No single user has complete control over sensitive processes
13 | - Regular rotation of critical roles
14 |
15 | ### Need-to-Know
16 | - Access granted only when job function requires it
17 | - Regular recertification of access rights
18 | - Immediate revocation when no longer needed
19 |
20 | ## Access Levels
21 |
22 | ### Level 1: Read-Only
23 | - View non-sensitive data
24 | - No modification capabilities
25 | - Basic reporting access
26 |
27 | ### Level 2: Standard User
28 | - Read and write within assigned scope
29 | - Cannot delete or modify security settings
30 | - Limited administrative functions
31 |
32 | ### Level 3: Power User
33 | - Extended permissions within domain
34 | - Can manage team resources
35 | - Subject to enhanced monitoring
36 |
37 | ### Level 4: Administrator
38 | - Full system access
39 | - Can modify security configurations
40 | - Requires MFA and enhanced logging
41 | - Regular security training mandatory
42 |
43 | ## Authentication Requirements
44 |
45 | | Access Level | Password | MFA | Session Timeout | IP Restriction |
46 | |--------------|----------|-----|-----------------|----------------|
47 | | Read-Only | Standard | Optional | 8 hours | No |
48 | | Standard User | Strong | Recommended | 4 hours | Optional |
49 | | Power User | Strong | Required | 2 hours | Recommended |
50 | | Administrator | Very Strong | Required | 1 hour | Required |
51 |
52 | ## Access Review Process
53 | - Quarterly review of all access permissions
54 | - Automated alerts for dormant accounts (90+ days)
55 | - Immediate revocation upon role change or termination
56 | - Annual access recertification for all users
57 |

126 |
127 | 🛡️ **Prevention Best Practices**:
128 | - Use environment variables for secrets
129 | - Implement secret management solutions (AWS Secrets Manager, HashiCorp Vault)
130 | - Enable secret scanning in git repositories
131 | - Use .gitignore to exclude sensitive files
132 | - Implement pre-commit hooks for credential detection

81 | - **Context**: ${context}
82 |
83 | ## Review Workflow
84 |
85 | Please perform a comprehensive security review following these steps:
86 |
87 | ### Step 1: Credential Scanning
88 | Use the \`credential-scanner\` tool to scan the ${targetType} for any exposed credentials, API keys, tokens, or secrets.
89 |
90 | ### Step 2: Prompt Injection Detection (if applicable)
91 | If reviewing user-facing inputs or prompts, use the \`prompt-injection-detector\` tool to check for injection attempts.
92 |
93 | ### Step 3: Consult Security Checklist
94 | Read the appropriate security checklist resource based on the operation type:
95 | - For database operations: \`security-checklist://database\`
96 | - For file operations: \`security-checklist://file\`
97 | - For web requests: \`security-checklist://web\`
98 | - For general operations: \`security-checklist://general\`
99 |
100 | ### Step 4: Review Against Security Policies
101 | Check the ${targetType} against relevant security policies:
102 | - Data handling: \`security-policy://data-classification\`
103 | - Access controls: \`security-policy://access-control\`
104 |
105 | ### Step 5: Threat Analysis
106 | Identify potential security threats specific to this ${targetType}:
107 | - What could go wrong?
108 | - What are the attack vectors?
109 | - What is the blast radius if compromised?
110 |
111 | ### Step 6: Provide Recommendations
112 | Based on the findings, provide:
113 | 1. **Critical Issues**: Must be fixed immediately
114 | 2. **High Priority**: Should be fixed before deployment
115 | 3. **Medium Priority**: Should be addressed in next iteration
116 | 4. **Best Practices**: Suggestions for improvement
117 |
118 | ### Step 7: Risk Assessment
119 | Provide an overall risk score (0-100) and recommendation:
120 | - 0-25: Low risk - Proceed with caution
121 | - 26-50: Medium risk - Address issues before proceeding
122 | - 51-75: High risk - Significant remediation required
123 | - 76-100: Critical risk - Do not proceed until fixed
124 |
125 | ### Step 8: Summary Table
126 | After completing all analysis steps, provide a summary table of all findings organized by severity:
127 |
128 | \`\`\`
129 | 📊 요약
130 |
131 | | 심각도 | 개수 | 파일/위치 |

176 | ${scenario}
177 |
178 | ## Data Sensitivity Level
179 | ${sensitivityLevel.toUpperCase()}
180 |
181 | ## Analysis Framework
182 |
183 | Please analyze this scenario for security threats using the following framework:
184 |
185 | ### 1. Asset Identification
186 | - What assets are involved? (data, systems, credentials)
187 | - What is their value and criticality?
188 | - Who has access to these assets?
189 |
190 | ### 2. Threat Modeling
191 | Identify potential threats using STRIDE methodology:
192 | - **S**poofing: Can identities be faked?
193 | - **T**ampering: Can data be modified?
194 | - **R**epudiation: Can actions be denied?
195 | - **I**nformation Disclosure: Can data be exposed?
196 | - **D**enial of Service: Can services be disrupted?
197 | - **E**levation of Privilege: Can permissions be escalated?
198 |
199 | ### 3. Risk Assessment
200 | For each identified threat, evaluate:
201 | - **Likelihood**: How likely is this threat? (Low/Medium/High)
202 | - **Impact**: What's the damage if it occurs? (Low/Medium/High/Critical)
203 | - **Risk Level**: Likelihood × Impact
204 |
205 | ### 4. Attack Vectors
206 | Identify possible attack vectors:
207 | - External attackers
208 | - Insider threats
209 | - Supply chain attacks
210 | - Social engineering
211 | - Technical vulnerabilities
212 |
213 | ### 5. Existing Controls
214 | Review current security controls:
215 | - Read \`security-policy://access-control\` for access control policies
216 | - Read \`security-policy://data-classification\` for data handling requirements
217 | - Check relevant security checklists
218 |
219 | ### 6. Control Gaps
220 | Identify missing or inadequate security controls:
221 | - What protections are missing?
222 | - Where are the weakest points?
223 | - What should be prioritized?
224 |
225 | ### 7. Mitigation Strategies
226 | Provide specific recommendations:
227 | - **Preventive Controls**: Stop threats before they occur
228 | - **Detective Controls**: Identify threats in progress
229 | - **Corrective Controls**: Respond to and recover from threats
230 | - **Compensating Controls**: Alternative protections
231 |
232 | ### 8. Compliance Considerations
233 | Based on sensitivity level "${sensitivityLevel}", ensure compliance with:
234 | ${sensitivityLevel === 'restricted' || sensitivityLevel === 'confidential' ?
235 | '- Encryption requirements\n- Access logging and monitoring\n- Multi-factor authentication\n- Regular access reviews' :
236 | '- Standard security practices\n- Basic access controls'}
237 |
238 | ### 9. Incident Response
239 | If this threat materializes:
240 | - What is the severity level? (Reference: \`security-policy://incident-response\`)
241 | - What is the response timeline?
242 | - Who should be notified?
243 | - What are the containment steps?
244 |
245 | ### 10. Risk Score and Recommendation
246 | Provide:
247 | - Overall risk score (0-100)
248 | - Risk level (Low/Medium/High/Critical)
249 | - Go/No-Go recommendation
250 | - Required security improvements
251 |
252 | ### 11. Summary Table
253 | After completing all analysis steps, provide a summary table of all identified threats organized by severity:
254 |
255 | \`\`\`
256 | 📊 요약
257 |
258 | | 심각도 | 개수 | 위협 유형 |

19 | ## Overview
20 |
21 | The Model Context Protocol (MCP) has three main component types that serve different purposes:
22 |
23 | | Component | Purpose | Direction | Side Effects |
24 | |-----------|---------|-----------|--------------|
25 | | **Tool** | Execute actions | AI → External System | Yes (write, execute, modify) |
26 | | **Resource** | Provide information | External System → AI | No (read-only) |
27 | | **Prompt** | Workflow templates | AI Internal | No (orchestration) |
28 |
29 | ---
30 |
31 | ## Tools
32 |
33 | ### What are Tools?
34 |
35 | **Tools** are functions that AI agents can call to **perform actions** or **execute operations**. They can have side effects and modify external state.
36 |
37 | ### When to Use Tools
38 |
39 | - ✅ When you need to **execute** an action
40 | - ✅ When operations have **side effects** (write, delete, send)
41 | - ✅ When you need to call **external APIs**
42 | - ✅ When you need **real-time processing**
43 |
44 | ### TypeScript SDK Implementation
45 |
46 | ```typescript
47 | import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js';
48 | import { z } from 'zod';
49 |

52 | version: '1.0.0',
53 | });
54 |
55 | // Basic Tool Example
56 | server.tool(
57 | 'example-tool', // Tool name
58 | 'Description of the tool', // Tool description
59 | {
60 | // Input schema using Zod
61 | parameter1: z.string().describe('Description of parameter1'),
62 | parameter2: z.number().optional().default(10),
63 | },
64 | async ({ parameter1, parameter2 }) => {
65 | // Tool implementation
66 | const result = await someOperation(parameter1, parameter2);
67 |
68 | return {
69 | content: [{
70 | type: 'text',
71 | text: `Result: ${result}`

97 | type: 'Instruction Override' },
98 | // ... more patterns
99 | ];
100 |

106 | const matches = text.match(pattern);
107 | if (matches) {
108 | detectedThreats.push({ type, severity, pattern: matches[0] });

123 | ### Tool Response Format
124 |
125 | ```typescript
126 | return {
127 | content: [
128 | {
129 | type: 'text', // or 'image', 'resource'
130 | text: 'Response text'
131 | }
132 | ],
133 | isError?: boolean // Optional error flag
134 | };
135 | ```
136 |

138 |
139 | ## Resources
140 |
141 | ### What are Resources?
142 |
143 | **Resources** are read-only data sources that AI agents can access to retrieve information. They provide context without modifying state.
144 |
145 | ### When to Use Resources
146 |
147 | - ✅ When you need to **provide documentation**
148 | - ✅ When you need to **expose read-only data**
149 | - ✅ When you need to **share reference materials**
150 | - ✅ When you need **static or semi-static content**
151 |
152 | ### TypeScript SDK Implementation
153 |
154 | ```typescript
155 | // Set up resource handler
156 | server.setResourceHandler({
157 | // List all available resources
158 | async listResources() {
159 | return {
160 | resources: [
161 | {
162 | uri: 'custom-scheme://resource-id',
163 | name: 'Human-readable name',
164 | description: 'Description of the resource',
165 | mimeType: 'text/plain', // or 'text/markdown', 'application/json'
166 | },
167 | // ... more resources
168 | ],
169 | };
170 | },
171 |
172 | // Read a specific resource
173 | async readResource({ uri }) {
174 | // Parse the URI
175 | const url = new URL(uri);
176 | const resourceId = url.hostname;
177 |
178 | // Fetch or generate content
179 | const content = getContentForResource(resourceId);
180 |
181 | return {
182 | contents: [{
183 | uri,
184 | mimeType: 'text/markdown',
185 | text: content,
186 | }],
187 | };
188 | },
189 | });
190 | ```
191 |
192 | ### Real Implementation Example: Security Checklists
193 |
194 | ```typescript
195 | // Define resource data
196 | const securityChecklists = {
197 | database: `# Database Security Checklist
198 |
199 | ## Pre-Operation Checks
200 | ✅ Verify database connection credentials are stored securely
201 | ✅ Confirm user has minimum necessary permissions
202 | ✅ Validate query input to prevent SQL injection
203 | ...`,
204 |
205 | email: `# Email Security Checklist
206 |
207 | ## Pre-Operation Checks
208 | ✅ Verify sender's email domain matches organization
209 | ✅ Confirm recipient authorization
210 | ...`,
211 | };
212 |
213 | // Implement resource handler
214 | server.setResourceHandler({
215 | async listResources() {
216 | return {
217 | resources: [
218 | {
219 | uri: 'security-checklist://database',
220 | name: 'Database Security Checklist',
221 | description: 'Security checklist for database operations',
222 | mimeType: 'text/markdown',
223 | },
224 | {
225 | uri: 'security-checklist://email',
226 | name: 'Email Security Checklist',
227 | description: 'Security checklist for email operations',
228 | mimeType: 'text/markdown',
229 | },
230 | ],
231 | };
232 | },
233 |
234 | async readResource({ uri }) {
235 | const url = new URL(uri);
236 | const type = url.hostname;
237 |
238 | const checklist = securityChecklists[type];
239 | if (!checklist) {
240 | throw new Error(`Unknown checklist type: ${type}`);
241 | }
242 |
243 | return {
244 | contents: [{
245 | uri,
246 | mimeType: 'text/markdown',
247 | text: checklist,
248 | }],
249 | };
250 | },
251 | });
252 | ```
253 |
254 | ### Resource URI Schemes
255 |
256 | ```typescript
257 | // Custom URI schemes
258 | 'security-checklist://database'
259 | 'security-policy://access-control'
260 | 'documentation://api-reference'
261 | 'config://server-settings'
262 |
263 | // Standard file URIs
264 | 'file:///path/to/file.md'
265 | 'https://example.com/resource'
266 | ```
267 |
268 | ---
269 |
270 | ## Prompts
271 |
272 | ### What are Prompts?
273 |
274 | **Prompts** are reusable templates that define workflows for AI agents. They orchestrate multiple tools and resources into a cohesive process.
275 |
276 | ### When to Use Prompts
277 |
278 | - ✅ When you need **multi-step workflows**
279 | - ✅ When you need **standardized processes**
280 | - ✅ When you need to **chain multiple operations**
281 | - ✅ When you need **templated instructions**
282 |
283 | ### TypeScript SDK Implementation
284 |
285 | ```typescript
286 | server.setPromptHandler({
287 | // List all available prompts
288 | async listPrompts() {
289 | return {
290 | prompts: [
291 | {
292 | name: 'prompt-name',
293 | description: 'Description of what this prompt does',
294 | arguments: [
295 | {
296 | name: 'argument1',
297 | description: 'Description of argument1',
298 | required: true,
299 | },
300 | {
301 | name: 'argument2',
302 | description: 'Description of argument2',
303 | required: false,
304 | },
305 | ],
306 | },
307 | // ... more prompts
308 | ],
309 | };
310 | },
311 |
312 | // Get a specific prompt with arguments
313 | async getPrompt({ name, arguments: args }) {
314 | if (name === 'prompt-name') {
315 | const arg1 = args?.argument1 || 'default';
316 | const arg2 = args?.argument2 || 'default';
317 |
318 | return {
319 | messages: [{
320 | role: 'user',
321 | content: {
322 | type: 'text',
323 | text: `Your prompt template here with ${arg1} and ${arg2}`,
324 | },
325 | }],
326 | };
327 | }
328 |
329 | throw new Error(`Unknown prompt: ${name}`);
330 | },
331 | });
332 | ```
333 |
334 | ### Real Implementation Example: Security Review Workflow
335 |
336 | ```typescript
337 | server.setPromptHandler({
338 | async listPrompts() {
339 | return {
340 | prompts: [
341 | {
342 | name: 'security-review',
343 | description: 'Comprehensive security review workflow',
344 | arguments: [
345 | {
346 | name: 'target_type',
347 | description: 'Type of target: code, data, or configuration',
348 | required: true,
349 | },
350 | {
351 | name: 'context',
352 | description: 'Additional context',
353 | required: false,
354 | },
355 | ],
356 | },
357 | ],
358 | };
359 | },
360 |
361 | async getPrompt({ name, arguments: args }) {
362 | if (name === 'security-review') {
363 | const targetType = args?.target_type || 'code';
364 | const context = args?.context || 'No context provided';
365 |
366 | return {
367 | messages: [{
368 | role: 'user',
369 | content: {
370 | type: 'text',
371 | text: `# Security Review Request
372 |
373 | ## Target Information
374 | - **Type**: ${targetType}
375 | - **Context**: ${context}
376 |
377 | ## Review Workflow

409 | **Generated**: ${new Date().toISOString()}`,
410 | },
411 | }],
412 | };
413 | }
414 |
415 | throw new Error(`Unknown prompt: ${name}`);
416 | },
417 | });
418 | ```
419 |
420 | ### Prompt Message Format
421 |
422 | ```typescript
423 | return {
424 | messages: [
425 | {
426 | role: 'user', // or 'assistant'

471 |
472 | ## Real-World Examples
473 |
474 | ### Example 1: Complete Security System
475 |
476 | ```typescript
477 | // TOOL: Active scanning
478 | server.tool(
479 | 'scan-for-vulnerabilities',
480 | 'Actively scan code for vulnerabilities',
481 | { code: z.string() },
482 | async ({ code }) => {
483 | // Performs analysis
484 | const vulnerabilities = await analyzeCode(code);
485 | return { content: [{ type: 'text', text: JSON.stringify(vulnerabilities) }] };
486 | }
487 | );
488 |
489 | // RESOURCE: Security guidelines

492 | return {
493 | resources: [{
494 | uri: 'guidelines://secure-coding',
495 | name: 'Secure Coding Guidelines',
496 | mimeType: 'text/markdown',
497 | }]
498 | };
499 | },
500 | async readResource({ uri }) {
501 | return {
502 | contents: [{
503 | uri,
504 | mimeType: 'text/markdown',
505 | text: '# Secure Coding Guidelines\n\n...',
506 | }]

533 | `
534 | }
535 | }]
536 | };
537 | },
538 | });
539 | ```
540 |
541 | ### Example 2: Email Security System
542 |
543 | ```typescript
544 | // TOOL: Send email (has side effect)
545 | server.tool(
546 | 'send-email',
547 | 'Send an email',
548 | {
549 | to: z.string().email(),
550 | subject: z.string(),
551 | body: z.string(),
552 | },
553 | async ({ to, subject, body }) => {
554 | await emailService.send(to, subject, body);
555 | return { content: [{ type: 'text', text: 'Email sent successfully' }] };
556 | }
557 | );
558 |
559 | // RESOURCE: Email policy (read-only)
560 | server.setResourceHandler({
561 | async listResources() {
562 | return {
563 | resources: [{
564 | uri: 'policy://email',
565 | name: 'Email Security Policy',
566 | mimeType: 'text/markdown',
567 | }]
568 | };
569 | },
570 | async readResource({ uri }) {
571 | return {
572 | contents: [{
573 | uri,
574 | mimeType: 'text/markdown',
575 | text: '# Email Policy\n\n- Always verify recipient\n- Never send PII externally',
576 | }]
577 | };
578 | },
579 | });
580 |
581 | // PROMPT: Safe email workflow
582 | server.setPromptHandler({
583 | async listPrompts() {
584 | return {
585 | prompts: [{
586 | name: 'safe-send-email',
587 | description: 'Send email with security checks',
588 | arguments: [
589 | { name: 'to', required: true },
590 | { name: 'subject', required: true },
591 | { name: 'body', required: true },
592 | ],
593 | }]
594 | };
595 | },
596 | async getPrompt({ arguments: args }) {
597 | return {
598 | messages: [{
599 | role: 'user',
600 | content: {
601 | type: 'text',
602 | text: `
603 | Before sending email:
604 | 1. Read email policy: \`policy://email\`
605 | 2. Verify recipient "${args?.to}" is authorized
606 | 3. Scan body for PII: use \`credential-scanner\` with text="${args?.body}"
607 | 4. If all checks pass, use \`send-email\` tool
608 | 5. Log the action
609 | `
610 | }
611 | }]
612 | };
613 | },
614 | });
615 | ```
616 |
617 | ---
618 |
619 | ## Best Practices
620 |
621 | ### Tools
622 |
623 | 1. **Clear Naming**: Use verb-based names (`scan-text`, `send-email`, `analyze-code`)
624 | 2. **Input Validation**: Always validate inputs with Zod schemas
625 | 3. **Error Handling**: Return structured errors in the response
626 | 4. **Idempotency**: When possible, make tools idempotent
627 | 5. **Documentation**: Provide clear descriptions for the tool and all parameters
628 |
629 | ```typescript
630 | // ✅ Good
631 | server.tool(
632 | 'validate-url-security',
633 | 'Validate URL for security issues including phishing, malware, and HTTPS enforcement',
634 | {
635 | url: z.string().url().describe('URL to validate for security'),
636 | strict_mode: z.boolean().optional().default(false).describe('Enable strict checks'),
637 | },
638 | async ({ url, strict_mode }) => {
639 | try {
640 | const result = await validateUrl(url, strict_mode);
641 | return { content: [{ type: 'text', text: JSON.stringify(result) }] };
642 | } catch (error) {
643 | return {
644 | content: [{ type: 'text', text: `Error: ${error.message}` }],
645 | isError: true
646 | };
647 | }
648 | }
649 | );
650 |
651 | // ❌ Bad
652 | server.tool('tool1', 'does stuff', { x: z.any() }, async ({ x }) => {
653 | return { content: [{ type: 'text', text: doStuff(x) }] };
654 | });
655 | ```
656 |
657 | ### Resources
658 |
659 | 1. **Consistent URI Schemes**: Use logical, hierarchical URI schemes
660 | 2. **Meaningful Names**: Use descriptive resource names
661 | 3. **Proper MIME Types**: Set correct MIME types (`text/markdown`, `application/json`)
662 | 4. **Error Handling**: Throw clear errors for invalid URIs
663 | 5. **Caching**: Consider caching for expensive resource generation
664 |
665 | ```typescript
666 | // ✅ Good
667 | const URI_SCHEMES = {
668 | checklist: 'security-checklist://',
669 | policy: 'security-policy://',
670 | guide: 'security-guide://',
671 | };
672 |
673 | server.setResourceHandler({
674 | async listResources() {
675 | return {
676 | resources: [
677 | {
678 | uri: `${URI_SCHEMES.checklist}database`,
679 | name: 'Database Security Checklist',
680 | description: 'Comprehensive checklist for database operations',
681 | mimeType: 'text/markdown',
682 | },
683 | ],
684 | };
685 | },
686 | async readResource({ uri }) {
687 | const url = new URL(uri);
688 | const scheme = url.protocol;
689 | const type = url.hostname;
690 |
691 | if (!Object.values(URI_SCHEMES).includes(scheme)) {
692 | throw new Error(`Invalid URI scheme: ${scheme}`);
693 | }
694 |
695 | const content = getContent(scheme, type);
696 | if (!content) {
697 | throw new Error(`Resource not found: ${uri}`);
698 | }
699 |
700 | return { contents: [{ uri, mimeType: 'text/markdown', text: content }] };
701 | },
702 | });
703 | ```
704 |
705 | ### Prompts
706 |
707 | 1. **Structured Workflows**: Break down complex tasks into clear steps
708 | 2. **Reference Tools/Resources**: Explicitly mention which tools and resources to use
709 | 3. **Argument Validation**: Provide clear descriptions for all arguments
710 | 4. **Error Scenarios**: Include error handling instructions
711 | 5. **Output Format**: Specify expected output format
712 |
713 | ```typescript
714 | // ✅ Good
715 | async getPrompt({ name, arguments: args }) {
716 | if (name === 'security-audit') {
717 | return {
718 | messages: [{
719 | role: 'user',
720 | content: {
721 | type: 'text',
722 | text: `
723 | # Security Audit for ${args?.target}
724 |
725 | ## Workflow Steps
726 |
727 | 1. **Read Guidelines**
728 | - Access: \`security-policy://audit-guidelines\`
729 | - Review all mandatory checks
730 |
731 | 2. **Run Scans**
732 | - Tool: \`credential-scanner\` with text="${args?.target}"
733 | - Tool: \`prompt-injection-detector\` with text="${args?.target}"
734 |
735 | 3. **Analyze Results**
736 | - Compare findings against guidelines
737 | - Calculate risk score
738 |
739 | 4. **Generate Report**
740 | - Format: Executive summary + detailed findings
741 | - Include actionable recommendations
742 |
743 | 5. **Error Handling**
744 | - If any tool fails, document the failure and continue
745 | - Final report should note any incomplete checks
746 |
747 | 6. **Summary Reporting**
748 | - Include a visual summary table at the end
749 | - Organize findings by severity (CRITICAL, HIGH, MEDIUM, LOW)
750 | - Use emoji indicators for quick scanning (🔴 🟠 🟡 🟢)
751 | - List locations/files/types affected
752 | - Example format:
753 | \`\`\`
754 | 📊 요약
755 | | 심각도 | 개수 | 위치 |
756 | |-------|------|------|
757 | | 🔴 CRITICAL | X | ... |
758 | \`\`\`
759 | `
760 | }
761 | }]
762 | };
763 | }
764 | }
765 | ```
766 |
767 | ### General Architecture
768 |
769 | 1. **Separation of Concerns**:
770 | - Tools for actions
771 | - Resources for data
772 | - Prompts for orchestration
773 |
774 | 2. **Composability**:
775 | - Design tools to be reusable
776 | - Make resources atomic and focused
777 | - Create prompts that combine multiple tools/resources
778 |
779 | 3. **Versioning**:
780 | - Version your tools, resources, and prompts
781 | - Maintain backward compatibility
782 | - Document breaking changes
783 |
784 | 4. **Security**:
785 | - Validate all inputs
786 | - Sanitize all outputs
787 | - Log security-relevant operations
788 | - Implement rate limiting
789 |
790 | 5. **Testing**:
791 | - Unit test each tool
792 | - Verify resource content
