11 ## 🚨 CRITICAL WARNING: VERIFICATION CHECKLIST MANDATORY FOR EVERY ENDPOINT
12
13 **YOU MUST CREATE A COMPLETE VERIFICATION CHECKLIST FOR EVERY ENDPOINT - NO EXCEPTIONS**
14
15 After dual-agent verification completes, you MUST:
16
17 1. **List EVERY parameter found** - If agents found 27 parameters, checklist MUST show all 27
18 2. **List EVERY response field found** - If agents found 15 fields, checklist MUST show all 15
19 3. **Verify each item in swagger.yaml** - Check type, required/optional, defaults match code
20 4. **Provide proof of completeness** - The checklist is auditable evidence you processed everything
21
22 **Without the complete enumerated checklist showing ALL parameters and ALL response fields individually, the endpoint is NOT considered verified.**
23
24 See Rule 5 section below for the exact checklist format that is MANDATORY for every single endpoint.

28 ## ⚠️ CRITICAL: CODE-FIRST DOCUMENTATION METHODOLOGY
29
30 **MANDATORY RULES - NO EXCEPTIONS - NO SHORTCUTS:**
31
32 ### Rule 1: NEVER Document Without Reading Source Code
33 - **NO guessing** based on API names (e.g., "versions" ≠ software versions)
34 - **NO copying** patterns from similar APIs without verification
35 - **NO assumptions** about what parameters do
36 - **NO confident documentation** without code evidence
37
38 ### Rule 2: CODE-FIRST Process for EVERY API
39 For each API, you MUST:
40
41 1. **Find Implementation in Source:**
42 ```
43 - Locate callback in web_api_v*.c registration
44 - Read the actual callback function code
45 - Understand what it ACTUALLY does (not what name suggests)
46 ```
47
48 2. **Trace Data Flow:**
49 ```
50 - What does callback call? (e.g., api_v2_contexts_internal)
51 - What flags/modes? (e.g., CONTEXTS_V2_VERSIONS)
52 - What does it return? (find output generation code)
53 - What parameters parsed? (check URL parsing code)
54 ```
55
56 3. **Verify Security:**
57 ```
58 - Read .acl value from web_api_v*.c
59 - Read .access value from web_api_v*.c
60 - Cross-reference with API_PERMISSIONS_ANALYSIS.md
61 - Document based on code, not assumptions
62 ```
63
64 4. **Document Based on Evidence:**
65 ```
66 - Write description matching actual behavior
67 - List parameters actually used by code
68 - Include response structure from output code
69 - For EVERY claim, you must point to specific code lines
70 ```
71
72 ### Rule 3: Verification Checklist (REQUIRED)
73 Before marking any API as documented, verify:
74 - [ ] Located callback function and read implementation
75 - [ ] Traced what the callback actually calls
76 - [ ] Found and read output generation code
77 - [ ] Listed parameters from URL parsing code
78 - [ ] Verified ACL/ACCESS from registration struct
79 - [ ] Can explain implementation when asked "what does it do?"
80 - [ ] Can point to specific code lines for each claim
81
82 ### Rule 4: Red Flags - STOP and Verify
83 If ANY of these occur, STOP and read code:
84 - ❌ API name suggests one thing but you haven't verified
85 - ❌ Copying documentation patterns without code check
86 - ❌ Can't explain implementation details when asked
87 - ❌ "Guessing" what parameters or responses are
88 - ❌ Writing "probably" or "likely" or "should"
89
90 ### Rule 5: Dual-Agent Parallel Verification (MANDATORY)
91 **YOU MUST USE THIS PATTERN FOR EVERY API - NO EXCEPTIONS**
92
93 For each API, you MUST spawn TWO agents in parallel (single message, multiple Task calls):
94
95 **Agent 1: Direct Code Analysis**
96 ```
97 Task(
98 subagent_type: "general-purpose",
99 prompt: "CRITICAL: Ignore ALL documentation files (*.md, *.yaml, swagger, comments).
100 Analyze ONLY the source code implementation of [API_PATH] endpoint in the
101 Netdata codebase at /home/costa/src/netdata-ktsaou.git
102
103 Your task:
104 1. Find the callback function registration in src/web/api/web_api_v*.c
105 2. Read the EXACT .acl and .access values from the registration struct
106 3. Trace through the actual C code implementation
107 4. Find ALL URL parameters parsed (parameter names, types, required/optional)
108 5. Follow the code execution flow to find the output generation function
109 6. Identify what JSON fields it returns based ONLY on the code logic
110 7. Provide specific file paths and line numbers for each step
111
112 Report:
113 - What the API actually does (based on code behavior, not name assumptions)
114 - Security: EXACT .acl value (e.g., HTTP_ACL_NOCHECK, HTTP_ACL_DASHBOARD)
115 - Security: EXACT .access value (e.g., HTTP_ACCESS_ANONYMOUS_DATA)
116 - Parameters: ALL parsed parameters with names, types, required/optional status
117 - The COMPLETE JSON response structure with ALL field names and types
118 - What each field represents (based on code, not guessing)
119 - File paths and line numbers as evidence for ALL claims
120
121 Do NOT read any documentation. Read ONLY C source code files."
122 )
123 ```
124
125 **Agent 2: Codex MCP Verification**
126 ```
127 Task(
128 subagent_type: "general-purpose",
129 prompt: "You have access to the Codex MCP tool (mcp__codex__codex). Use it to analyze
130 the [API_PATH] endpoint implementation.
131
132 Call the mcp__codex__codex tool with this prompt:
133 'CRITICAL: Ignore ALL documentation files (*.md, *.yaml, swagger, comments).
134 Analyze ONLY the source code implementation of [API_PATH] endpoint.
135 Find:
136 1) The callback function registration in src/web/api/web_api_v*.c
137 2) The EXACT .acl and .access values from the registration struct
138 3) ALL URL parameters parsed (names, types, required/optional)
139 4) Trace through the actual C code implementation
140 5) Find the output generation function
141 6) Describe the COMPLETE JSON response structure with ALL fields and types
142
143 Report what the API actually does, its security settings (.acl, .access),
144 all parameters, and complete response structure based on code execution flow
145 with specific file paths and line numbers.'
146
147 Set the working directory to: /home/costa/src/netdata-ktsaou.git
148
149 After Codex completes, report its findings back to me verbatim."
150 )
151 ```
152
153 **Your Reconciliation Role (MANDATORY):**
154 1. Wait for BOTH agents to complete
155 2. Compare their findings line-by-line
156 3. If they match exactly → document with high confidence
157 4. If they differ → YOU MUST:
158 - Read the actual source code yourself at the specific lines both reported
159 - Determine ground truth from the code
160 - Explain which agent was correct and why
161 - NEVER choose arbitrarily - verify against actual code
162 5. Document ONLY verified facts that both agents agree on OR that you verified yourself
163
164 **After Verification, IMMEDIATELY Update swagger.yaml:**
165
166 When both agents complete, you MUST immediately update swagger.yaml:
167
168 **Update swagger.yaml (OPENAPI SPECIFICATION):**
169
170 **CRITICAL: swagger.yaml is the OpenAPI specification - accurate technical documentation for API consumers**
171
172 **MANDATORY CHECKLIST - ALL items MUST be completed for EVERY endpoint:**
173
174 1. **Description Section:**
175 - ✅ Complete behavioral description (what the API does from user perspective)
176 - ✅ Use cases and when to use this endpoint
177 - ✅ How it works (user-understandable flow)
178 - ✅ Security & Access Control section (translate .acl/.access to user terms)
179 -**NO code references** (no file paths, no line numbers, no implementation details)
180 -**NO internal jargon** (no callback names, no function names, no struct names)
181
182 2. **Parameters Section:**
183 -**VERIFY EVERY parameter exists** in swagger.yaml parameters list
184 -**ADD any missing parameters** that agents found in code
185 -**VERIFY parameter descriptions** match actual code behavior
186 -**VERIFY required vs optional** matches code implementation
187 -**VERIFY default values** match code defaults
188 -**VERIFY parameter types** (string, integer, boolean, etc.)
189
190 3. **Response Schema Section:**
191 -**VERIFY response schema** matches what agents found in code
192 -**ADD missing response fields** that agents discovered
193 -**VERIFY field types** and nested object structures
194 -**VERIFY all response codes** (200, 400, 403, 404, 500, 504, etc.)
195 -**UPDATE schema references** if needed (create new schemas for complex responses)
196
197 4. **Security Section:**
198 -**VERIFY security section** matches ACL/ACCESS from code
199 -**UPDATE security requirements** if needed
200
201 **Update SWAGGER_DOCUMENTATION_PROGRESS.md (INTERNAL TRACKING):**
202
203 For EVERY endpoint, you MUST create a detailed verification checklist in this file to prove completeness:
204
205 ```markdown
206 ### /api/vX/endpoint Verification Checklist
207
208 #### Agent Reports Comparison
209 - [ ] Both agents agree on security (ACL, ACCESS)
210 - [ ] Both agents found same parameter count: Agent1=N, Agent2=N
211 - [ ] Both agents found same response structure
212 - [ ] Conflicts resolved: [list any differences found and how resolved]
213
214 #### swagger.yaml Updates Verification
215 1. **Description Section:**
216 - [ ] Behavioral description updated
217 - [ ] Use cases documented
218 - [ ] Security & Access Control translated from code
219
220 2. **Security Section:**
221 - [ ] Verified: ACL=X (file:line), ACCESS=Y (file:line)
222 - [ ] swagger.yaml security section matches code
223
224 3. **Parameters Section:**
225 - [ ] Parameter count: Agents found=N, swagger.yaml has=N ✓
226 - [ ] Each parameter verified (list ALL):
227 - [ ] param1: type=X, required=Y, default=Z ✓
228 - [ ] param2: type=X, required=Y, default=Z ✓
229 - ... [EVERY parameter must be listed]
230
231 4. **Response Schema Section:**
232 - [ ] Response 200 verified (list ALL fields):
233 - [ ] field1: type=X, description ✓
234 - [ ] field2: type=X, nested structure ✓
235 - ... [EVERY response field must be listed]
236 - [ ] Error responses verified:
237 - [ ] 400: description matches code behavior
238 - [ ] 403: description matches code behavior
239 - [ ] 404: description matches code behavior
240 - [ ] 504: description matches code behavior
241
242 #### Code References (for internal tracking)
243 - **Callback:** function_name
244 - **Registration:** file:line
245 - **Implementation:** file:line-range
246 - **Security:** ACL=X (file:line), ACCESS=Y (file:line)
247
248 **VERIFICATION COMPLETE** - All checklist items verified
249 ```
250
251 **CRITICAL:** The checklist ensures you process EVERY piece of information both agents provided.
252 If agents found 27 parameters, the checklist MUST show all 27 verified.
253 If agents found 15 response fields, the checklist MUST show all 15 verified.
254
255 **Separation of Concerns:**
256 - **swagger.yaml** = Complete OpenAPI specification (accurate technical API documentation)
257 - **SWAGGER_DOCUMENTATION_PROGRESS.md** = Verification tracking (how we verified completeness)
258
259 **This means ONE dual-agent verification → COMPLETE swagger.yaml updates + VERIFICATION CHECKLIST**
260
261 You complete multiple tasks simultaneously:
262 - Description verified ✅
263 - Parameters verified (ALL of them, with checklist proof) ✅
264 - Response schema verified (ALL fields, with checklist proof) ✅
265 - Security verified ✅
266 - swagger.yaml updated ✅
267 - Verification checklist created in SWAGGER_DOCUMENTATION_PROGRESS.md ✅
268
269 **Why This is Mandatory:**
270 - Single-agent analysis can miss implementation details
271 - Dual verification catches errors and omissions
272 - Cross-validation ensures 100% accuracy
273 - Tested on `/api/v3/versions` - Codex caught details the code-reading agent missed
274 - Provides redundancy for unattended work
275
276 **Example Success:** `/api/v3/versions` verification found both agents agreed on core structure,
277 but Codex discovered the response includes `"api": 2` and `"timings"` fields that the first
278 agent missed. Manual verification confirmed Codex was correct (src/database/contexts/api_v2_contexts.c:1302, 1468)
279
280 ### Consequences of Violations
281 Documentation based on assumptions instead of code:
282 - ❌ Creates false, misleading documentation
283 - ❌ Wastes developer time debugging wrong APIs
284 - ❌ Breaks systems built on false assumptions
285 - ❌ Destroys trust in ALL documentation
286 - ❌ Creates maintenance nightmares
287
288 **Example of Failure:**
289 `/api/v3/versions` was documented as "returns Netdata agent version string (e.g., 'v1.40.0')"
290 but actually returns metadata version hashes for cache invalidation. Complete failure from
291 not reading the code.

294
295 ## Overview
296
297 This file tracks the comprehensive OpenAPI specification project to ensure:
298 1. All Netdata APIs are **accurately** documented in `swagger.yaml` based on source code
299 2. All parameters are documented from **actual URL parsing code**
300 3. All outputs are documented from **actual response generation code**
301 4. All security is documented from **actual ACL/ACCESS values**
302 5. All documentation refers to v3 as latest
303 6. v1 and v2 APIs are marked as obsolete
304
305 **Process:**
306 - MUST read source code before documenting in swagger.yaml
307 - MUST verify every claim against code
308 - MUST NOT make assumptions based on API names
309 - MUST use dual-agent verification for code analysis
310 - User-facing documentation (learn/docs, etc.) will be updated AFTER swagger.yaml is complete
311

596
597 ## PHASE 1: API Documentation - ⚠️ NEEDS COMPLETE CODE VERIFICATION
598
599 **Critical Status Update:**
600 - **Total APIs:** 68
601 - **Code Verified with Complete Checklist:** 0/68 (0%) - ALL need verification with enumerated checklist
602 - **Need Verification:** 68/68 (100%) - ALL APIs need complete verification
603 - **V3 APIs:** 0/27 verified (100% unverified) ⚠️
604 - **V2 APIs:** 0/17 verified (100% unverified) ⚠️
605 - **V1 APIs:** 0/24 verified (100% unverified) ⚠️
606
607 **What Was Documented (UNVERIFIED):**
608 1. **API Descriptions:** Written based on API names and assumptions - **NOT VERIFIED against actual code**
609 2. **Parameter Documentation:** Guessed from similar APIs or documentation - **NOT VERIFIED from implementation**
610 3. **Response Documentation:** Assumed based on patterns - **NOT VERIFIED from output generation code**
611 4. **Security Documentation:** May be accurate (from registration structs) but **endpoint behavior NOT VERIFIED**
612
613 **Known Issues:**
614 - `/api/v3/versions` was completely wrong until code verification
615 - Documented as "returns agent version string" but actually returns cache invalidation hashes
616 - **All other 67 APIs may have similar errors**
617
618 **Required Action:**
619 Must apply CODE-FIRST METHODOLOGY to all 67 remaining APIs:
620 1. Read callback implementation
621 2. Trace data flow
622 3. Find output generation
623 4. Verify parameters from parsing code
624 5. Update documentation with verified facts
625
626 **Status Change Date:** 2025-10-04
627 **Original Documentation Date:** 2025-10-02 (SUSPECT - based on assumptions)

630
631 ## PERMISSIONS ANALYSIS - COMPLETE ✅
632
633 **Summary:**
634 Comprehensive analysis of ACL (Access Control Lists) and HTTP_ACCESS permissions completed for all 68 APIs.
635
636 **Analysis Document:** `API_PERMISSIONS_ANALYSIS.md`
637
638 **Key Findings:**
639
640 1. **ACLK-Only APIs (6 total - Cloud Access Required):**
641 - `/api/v*/rtc_offer` - WebRTC setup (requires: SIGNED_ID + SAME_SPACE)
642 - `/api/v*/bearer_protection` - Enable/disable bearer auth (requires: SIGNED_ID + SAME_SPACE + VIEW_AGENT_CONFIG + EDIT_AGENT_CONFIG)
643 - `/api/v*/bearer_get_token` - Generate bearer tokens (requires: SIGNED_ID + SAME_SPACE)
644 - ⚠️ These APIs are ONLY accessible via Netdata Cloud (ACLK), not via direct HTTP
645
646 2. **Public Data APIs (47 total - No Authentication Required):**
647 - Most metrics, alerts, and metadata APIs
648 - Require `HTTP_ACCESS_ANONYMOUS_DATA`
649 - Subject to IP-based ACL restrictions in netdata.conf
650
651 3. **Public Info APIs (12 total - Unrestricted):**
652 - Have `HTTP_ACL_NOCHECK` - bypass ACL checking
653 - Includes: info, versions, progress, settings, me, claim, stream_info
654
655 4. **Special Permission Handling:**
656 - `/api/v*/config` - Permissions checked per-action internally
657 - `/api/v*/function` - Permissions checked per-function by plugins
658 - `/api/v1/registry` - Manages ACL internally
659 - `/api/v1/manage` - Manages access internally
660
661 **ACL Categories:**
662 - `HTTP_ACL_METRICS` - Metrics data (configurable via "allow dashboard from")
663 - `HTTP_ACL_ALERTS` - Alerts access (configurable via "allow dashboard from")
664 - `HTTP_ACL_NODES` - Node information (configurable via "allow dashboard from")
665 - `HTTP_ACL_FUNCTIONS` - Functions execution (configurable via "allow dashboard from")
666 - `HTTP_ACL_DYNCFG` - Dynamic configuration (configurable via "allow dashboard from")
667 - `HTTP_ACL_BADGES` - Badge generation (configurable via "allow badges from")
668 - `HTTP_ACL_MANAGEMENT` - Management operations (configurable via "allow management from")
669 - `HTTP_ACL_ACLK` - Cloud-only access
670 - `HTTP_ACL_NOCHECK` - No restrictions
671
672 **Next Action:** ✅ COMPLETE - Security documentation added to all 68 APIs
673
674 **Completion Date:** 2025-10-02
675
676 ---
677
678 ## SECURITY DOCUMENTATION IN SWAGGER - ⚠️ PARTIALLY VERIFIED
679
680 **Summary:**
681 All 68 APIs have security documentation in swagger.yaml based on ACL/ACCESS flags from registration structs. **However, actual endpoint behavior and parameter handling NOT VERIFIED.**
682
683 **What Was Added:**
684
685 1. **Security Schemes (components/securitySchemes):**
686 - `bearerAuth` - Bearer token authentication (optional for public data APIs)
687 - `aclkAuth` - ACLK-only authentication (cloud access required)
688 - `ipAcl` - IP-based ACL documentation (informational)
689
690 2. **Per-Endpoint Security Documentation:**
691
692 **ACLK-Only APIs (6 total):**
693 - Security field: `security: [aclkAuth: []]`
694 - Description: Detailed ACLK access requirements, permissions, and restrictions
695 - APIs: rtc_offer, bearer_protection, bearer_get_token (v2 & v3)
696
697 **Public Data APIs (50 total):**
698 - Security field: `security: [{}, bearerAuth: []]` (no auth OR bearer auth)
699 - Description: Bearer protection optional, IP ACL restrictions, access methods
700 - APIs: data, weights, contexts, alerts, functions, badges, config, etc. (v1, v2, v3)
701
702 **Always Public APIs (12 total):**
703 - Security field: NONE (intentionally omitted - indicates always public)
704 - Description: Always accessible, no restrictions, cannot be secured
705 - APIs: info, versions, progress, settings, claim, me, registry, manage
706
707 3. **Security Section Format:**
708 Each API's description includes a **Security & Access Control** section with:
709 - Access type (ACLK-Only / Public Data / Always Public)
710 - Authentication requirements
711 - IP-based ACL restrictions (where applicable)
712 - Access methods (HTTP, Cloud, external tools)
713 - Configuration references (netdata.conf settings)
714
715 **Verification Status:**
716 - ✅ 68/68 APIs have "Security & Access Control" in descriptions (based on registration flags)
717 - ✅ 6 ACLK-only APIs have `aclkAuth` security scheme (verified from ACL flags)
718 - ✅ 50 Public Data APIs have optional bearer auth `[{}, bearerAuth: []]` (verified from ACCESS flags)
719 - ✅ 12 Always Public APIs have NO security field (verified from HTTP_ACL_NOCHECK)
720 - ✅ All security flags match API_PERMISSIONS_ANALYSIS.md
721 - ⚠️ **Actual endpoint behavior and parameter security NOT VERIFIED from implementation code**
722
723 **Security Documentation Date:** 2025-10-04 (flags verified, behavior unverified)
724
725 ---
726
727 ## PHASE 2: Document Response Schemas (BLOCKED)
728
729 **Status:** BLOCKED until Phase 1 code verification complete
730
731 **Goal:** Add comprehensive response schema documentation for all 68 APIs
732
733 **Blockers:**
734 - Cannot document response schemas without knowing actual implementation
735 - Current API descriptions may be wrong (like `/api/v3/versions` was)
736 - Must verify what endpoints ACTUALLY return before documenting schemas
737
738 **Approach (when unblocked):**
739 1. Read output generation code for each API
740 2. Extract actual JSON structure from code
741 3. Define reusable schema components
742 4. Document verified success responses with schemas
743 5. Document error responses from actual error handling code
744 6. Add response examples from verified output
745
746 ---
747
748 ## PHASE 3: Mark V1/V2 as Obsolete (Partially Complete)
749
750 **Status:**
751 - ✅ V2 APIs: All marked as deprecated with migration notes
752 - ⏳ V1 APIs: Some marked as deprecated, need comprehensive review
753 - ⏳ Add prominent deprecation warnings in descriptions
754 - ⏳ Update OpenAPI metadata to indicate V3 as current version
755
756 ---
757
758 ## PHASE 4: Final Validation (Pending)
759
760 **Tasks:**
761 - Validate swagger YAML syntax
762 - Check all references are valid
763 - Ensure consistency across all endpoints
764 - Verify all examples are correct
765 - Test with swagger validation tools
766
767 ---
768
769 ## SUMMARY: CRITICAL DOCUMENTATION STATUS
770
771 **Overall Progress:** 0% verified with complete checklist, 100% need verification
772
773 **Immediate Priority:** Apply CODE-FIRST METHODOLOGY with COMPLETE ENUMERATED CHECKLIST to verify all 68 APIs
774
775 **Methodology in Place:**
776 - ✅ Rules documented at top of file
777 - ✅ Verification checklist defined
778 - ✅ Red flags identified
779 - ✅ Sub-agent pattern recommended
780 - ✅ Example failure documented (`/api/v3/versions`)
781 - ✅ All status markers updated to reflect verification need
782
783 **Next Steps:**
784 1. Use sub-agents or direct code analysis to verify each API
785 2. For each API, must trace: callback → implementation → output → parameters
786 3. Update swagger.yaml with verified facts only
787 4. Mark APIs as ✅ verified only after code confirmation
788 5. Cannot proceed to Phase 2 until Phase 1 verification complete
789
790 **Last Updated:** 2025-10-04
791 **Next Action:** Begin CODE VERIFICATION of 67 unverified APIs using CODE-FIRST methodology
792

3241 - `user_role` - HTTP_USER_ROLE from authenticated web client
3242 - `access` - HTTP_ACCESS flags from authenticated web client
3243 - `cloud_account_id` - nd_uuid_t from authenticated web client
3244 - `client_name` - string from authenticated web client
3245
3246 **Expiration:**
3247 - Default: 24 hours from creation
3248 - Token is stored in `netdata_authorized_bearers` dictionary

3255
3256 ### REMOTE HOST HANDLING
3257
3258 - If `host != localhost`, delegates to `call_function_bearer_get_token()`
3259 - Converts to function call via `rrd_function_run()` with function name `RRDFUNCTIONS_BEARER_GET_TOKEN`
3260 - Passes all auth context via JSON payload including user_role, access array, cloud_account_id, client_name

3369 #### `/api/v2/claim` - 98% SHARED WITH V3
3370 **Shared Implementation:** Both V2 and V3 call the same `api_claim()` function with version parameter.
3371
3372 **Single Difference:**
3373 - **V2** (`version=2`): Returns **plain text** error messages on validation failures
3374 - **V3** (`version=3`): Returns **JSON** error responses on validation failures
3375
3376 All other aspects (parameters, success responses, claiming logic, security) are identical. See `/api/v3/claim` checklist for complete parameter and response documentation.
3377
3378 ### Build Status:
3379 - `ENABLE_API_v2`: **Hardcoded enabled** in `src/web/api/web_api.h`
3380 - Status: **ACTIVE in production** (NOT obsolete despite earlier notes)
3381 - Documentation: Referenced in current Netdata docs (API tokens, replication)
3382
3383 **ALL 17 V2 APIs VERIFIED**
