3
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
4
+
5
+THE MOST IMPORTANT RULES ARE:
6
+
7
+1. You MUST ALWAYS find the root cause of a problem, before giving a solution.
8
+2. Patching without understanding the problem IS NOT ALLOWED.
9
+3. Before patching code, we MUST understand the code base and the potential implications of our changes.
10
+4. We do not duplicate code. We first check if similar code already exists and to reuse it.
11
+
12
+## C code
13
+- gcc, clang, glibc and muslc
14
+- libnetdata.h includes everything in libnetdata (just a couple of exceptions) so there is no need to include individual libnetdata headers
15
+- Functions with 'z' suffix (mallocz, reallocz, callocz, strdupz, etc.) handle allocation failures automatically by calling fatal() to exit Netdata
16
+- The freez() function accepts NULL pointers without crashing
17
+- Resuable, generic, module agnostic code, goes to libnetdata
18
+- Double linked lists are managed with DOUBLE_LINKED_LIST_* macros
19
+- json-c for json parsing
20
+- buffer_json_* for manual json generation
21
+
22
+## Naming Conventions
23
+- "Netdata Agent" (capitalized) when referring to the product
24
+- "`netdata`" (lowercase, code-formatted) when referring to the process
25
+- See DICTIONARY.md for precise terminology

36

- **Simple Formats**: A duration can be specified using a number followed by a unit, such as `5m` (5 minutes), `2h` (2 hours), or `1d` (1 day). Fractional numbers are also supported, such as `1.5d`, `3.5mo` or `1.2y`.
38
39
+- **Full Unit Names**: In addition to abbreviated units, Netdata also supports full unit names for better readability. For example:
40
+ - `7 days` or `7days` (equivalent to `7d`)
41
+ - `2 hours` or `2hours` (equivalent to `2h`)
42
+ - `30 seconds` or `30seconds` (equivalent to `30s`)
43
+ - All unit names are case-insensitive: `7 DAYS`, `7 Days`, `7 days` are all valid
44
+
45
- **Complex Formats**: A duration can also be composed of multiple units added together. For example:
46
- `1y2mo3w4d` represents 1 year, 2 months, 3 weeks, and 4 days.
47
- `15d-12h` represents 15 days minus 12 hours (which equals 14 days and 12 hours).
48
+ - `2 hours 30 minutes` or `2hours30minutes` (equivalent to `2h30m`)

92
+### "Ago" Suffix
93
+
94
+Netdata supports the "ago" suffix to express durations in the past. When a duration expression ends with "ago" (case-insensitive), the resulting value is negated. This provides a more natural way to express past time intervals:
95
+
96
+- **`7 days ago`** is equivalent to **`-7d`**
97
+- **`2 hours ago`** is equivalent to **`-2h`**
98
+- **`30 minutes ago`** is equivalent to **`-30m`**
99
+
100
+The "ago" suffix works with all duration formats:
101
+- Abbreviated: `7d ago`, `2h ago`, `30m ago`
102
+- Full names: `7 days ago`, `2 hours ago`, `30 minutes ago`
103
+- Complex expressions: `2 hours 30 minutes ago`, `1d12h ago`
104
+- Case variations: `7 days AGO`, `7 days Ago`, `7daysago`
105
+
106
+Note: If you use a negative duration with "ago", it results in a positive value: `-7 days ago` = 7 days (double negative).

+# ASSISTANTS **MUST** FOLLOW THESE RULES
2
+
3
+1. This is a new application. No need for backward compatibility.
4
+2. When a task is concluded, existing `eslint` configuration MUST show zero errors and zero warnings.
5
+3. Do not use any deprecated or legacy code. This is a new application, so everything should be up-to-date.
6
+4. Avoid default values to parameters. Always call functions with explicit parameters and if adding new parameters, ensure all uses are updated accordingly.
7
+5. Work in small increments so that the user can follow up with your changes and provide feedback.
8
+6. When dealing with issues, ALWAYS FIND THE ROOT CAUSE and fix it, rather than applying a workaround.
9
+
10
+## REFACTORING
11
+1. When migrating/refactoring code, NEVER use fallbacks. Let the code fail so that we can identify and fix issues immediately.
12
+2. Do not keep code for future use. If you need to implement a feature later, do it then.
13
+3. FAIL FAST strategy, not fallback silently.
14
+4. Remove any unused code, including imports, variables, functions, etc. If you need to use it later, re-implement it.
15
+
16
+## WHEN COMMITING
17
+1. BEFORE committing make sure `eslint` shows zero errors and zero warnings.
18
+1. Commit with git add filename1 filename2 etc, to avoid committing unnecessary files.
19
+2. Always do a git diff before committing to ensure only intended changes are included.

+# MCP Web Client - Chat History Implementation
27
+
28
+This document describes the chat history implementation and message handling logic in the MCP web client.
29
+
30
+IMPORTANT:
31
+Each chat in this application is INDEPENDENT OF THE OTHERS. There shouldn't be ANY global configuration of ANY kind.
32
+Each chat has its own UNIQUE configuration, its own messages and data, and chats run IN PARALLEL. So, the user is able
33
+to SWITCH BETWEEN THEM AT ANY TIME without any issues, and let them run while he chats on another one of them.
34
+
35
+CRITICAL:
36
+No sharing between chats. No global settings. No shared structures.
37
+
38
+CRITICAL:
39
+NO HARDCODING OF PROVIDERS AND MODELS ALLOWED! The providers and models are coming from llm-proxy.js and are USER CONFIGURABLE.
40
+Even llm-proxy.js itself has an internal list only to help the user configure the providers and models.
41
+So, the application MUST NOT hardcode any providers or models. It should use the ones configured by the user.
42
+
43
+## Message Roles and Types
44
+
45
+The chat history uses a role-based system to distinguish different types of messages:
46
+
47
+### Regular Conversation Roles
48
+- `user` - Regular user messages
49
+- `assistant` - LLM assistant responses
50
+- `system` - System prompt (only sent at the beginning of conversations)
51
+
52
+### Special System Roles (Never sent to LLM API)
53
+- `system-title` - Request to generate a chat title
54
+- `title` - Response containing the generated title
55
+- `system-summary` - Request to summarize the conversation
56
+- `summary` - Response containing the conversation summary (acts as checkpoint)
57
+- `accounting` - Token accounting checkpoint (preserves cumulative token counts)
58
+
59
+### Legacy Types (for backward compatibility)
60
+- `tool-results` - Results from tool executions
61
+- `tool-call` - Tool invocation records
62
+
63
+## Visual Styling
64
+
65
+Each role has distinct visual styling:
66
+- **system-title/system-summary**: Border with icon (📝 for title, 📋 for summary)
67
+- **title**: Italicized with blue border
68
+- **summary**: Yellow border with "📌 Conversation Summary (Checkpoint)" header
69
+- **accounting**: Horizontal line with token counts (💰 icon)
70
+- **Regular messages**: Standard chat bubbles
71
+
72
+## API Message Building (`buildMessagesForAPI`)
73
+
74
+When building messages for the LLM API:
75
+
76
+1. **System roles are filtered out**: Messages with roles `system-title`, `system-summary`, `title`, `summary`, and `accounting` are never sent to the API
77
+
78
+2. **Summary checkpoint behavior**:
79
+ - Finds the latest `summary` message
80
+ - Only includes messages AFTER the summary
81
+ - The summary content is prepended to the system prompt as "Previous Conversation Summary:"
82
+ - This prevents sending the entire conversation history after summarization
83
+
84
+3. **System prompt inclusion**: Added when it's the first user message in the conversation or after a checkpoint
85
+
86
+## Cache Control Management
87
+
88
+### Cache Position Tracking
89
+- Each assistant message stores `cacheControlIndex` indicating where cache control was applied
90
+- This allows freezing the cache position for cost-effective operations
91
+
92
+### Frozen Cache for Summaries
93
+- When requesting a summary, `buildMessagesForAPI(chat, provider, true)` freezes the cache
94
+- The cache control mark stays at its previous position instead of advancing
95
+- This prevents the 25% cache creation surcharge on the entire conversation
96
+
97
+## Context Window Calculation
98
+
99
+### Token Components
100
+The context window includes:
101
+- `promptTokens` - Regular input tokens
102
+- `cacheReadInputTokens` - Cached tokens being reused (90% discount)
103
+- `cacheCreationInputTokens` - New tokens being cached (25% surcharge)
104
+- `completionTokens` - Output tokens (will be part of next request's input)
105
+
106
+### Special Handling by Role
107
+- **Regular messages**: Full token calculation including all components
108
+- **system-title, title, system-summary**: Maintains current context window (no change)
109
+- **summary**: Returns only the summary's completion tokens (context is reset)
110
+
111
+### Why Include Completion Tokens
112
+The assistant's response (completion tokens) becomes part of the conversation history sent in the next request, so they must be counted as part of the context.
113
+
114
+## Tool Inclusion Modes
115
+
116
+The `toolInclusionMode` property controls how tools are included:
117
+- `auto` - Automatic inclusion based on context
118
+- `cached` - Always include tools with cache control (default)
119
+- `all-on` - Include all tools
120
+- `all-off` - Exclude all tools
121
+- `manual` - User controls individual tool inclusion
122
+
123
+## Summary Workflow
124
+
125
+1. User clicks "Summarize Conversation"
126
+2. System sends `system-summary` request with frozen cache
127
+3. LLM responds with summary
128
+4. Summary is stored with role `summary` and acts as checkpoint
129
+5. Context window resets to show only summary tokens
130
+6. Future API calls include summary in system prompt but exclude all prior messages
131
+
132
+## Title Generation Workflow
133
+
134
+1. System sends `system-title` request
135
+2. LLM responds with title
136
+3. Both messages are stored but never sent in future API calls
137
+4. Context window remains unchanged throughout the process
138
+
139
+## Important Implementation Notes
140
+
141
+1. **Message Filtering**: The `buildMessagesForAPI` function is the single source of truth for what gets sent to the LLM
142
+2. **Context Calculation**: The `calculateContextWindowTokens` function handles special cases based on message roles
143
+3. **Cache Efficiency**: Summary requests don't advance the cache, saving costs on large conversations
144
+4. **Checkpoint Behavior**: Summaries create a hard boundary - messages before them are never sent again
145
+
146
+## Live vs Loaded Chats - Unified Architecture
147
+
148
+**Critical Design Principle**: Both live and loaded chats use identical mechanics. The chat history stores only raw data - no pre-calculated statistics.
149
+
150
+### Why No Stored Statistics
151
+- All statistics (token counts, context window size, etc.) are calculated on-the-fly
152
+- This ensures consistency between live and loaded chats
153
+- Prevents stale or incorrect statistics from persisting
154
+- Simplifies the data model - chat history contains only raw messages and responses
155
+
156
+### Unified Processing
157
+- `convertMessageToEvents()` transforms stored messages into rendering events
158
+- The same rendering pipeline handles both live and historical messages
159
+- Token counting, context calculation, and display updates work identically
160
+
161
+## Context Window Calculation Details
162
+
163
+The context window is calculated dynamically by `calculateContextWindowTokens()`:
164
+
165
+### For Regular Messages (user/assistant)
166
+```
167
+Context = promptTokens + cacheReadInputTokens + cacheCreationInputTokens + completionTokens
168
+```
169
+- Includes all token types from the latest request
170
+- Completion tokens are counted because they'll be sent in the next request
171
+
172
+### For System Title Messages (system-title/title)
173
+- **No change to context window**
174
+- Returns the current context size unchanged
175
+- These messages are UI-only and don't affect the conversation flow
176
+
177
+### For System Summary Messages
178
+- **system-summary request**: No change (maintains current context)
179
+- **summary response**: Context resets to only the summary's completion tokens
180
+- This reflects that future requests will only include the summary
181
+
182
+### Context Window After Operations
183
+1. **Normal conversation**: Accumulates tokens with each exchange
184
+2. **After title generation**: Unchanged from before
185
+3. **After summarization**: Shows only summary tokens (typically much smaller)
186
+4. **Loading a chat**: Recalculates from the latest token history entry
187
+
188
+### Token History Storage
189
+- Raw token usage is stored per request in `tokenUsageHistory`
190
+- Each entry contains: `promptTokens`, `completionTokens`, `cacheReadInputTokens`, `cacheCreationInputTokens`
191
+- No derived values or totals are stored - everything is calculated when needed
192
+
193
+## Accounting Nodes - Preserving Token History
194
+
195
+### Purpose
196
+When users edit messages or retry after errors, messages are removed from the chat history. This would normally cause the cumulative token counters to lose track of the actual costs incurred. Accounting nodes solve this by creating checkpoints that preserve the token counts before messages are discarded.
197
+
198
+### Structure
199
+```javascript
200
+{
201
+ role: 'accounting',
202
+ timestamp: '...',
203
+ cumulativeTokens: {
204
+ inputTokens: 12500,
205
+ outputTokens: 8300,
206
+ cacheReadTokens: 5000,
207
+ cacheCreationTokens: 1200
208
+ },
209
+ reason: 'Message edited', // or 'Retry after error'
210
+ discardedMessages: 5 // Number of messages removed
211
+}
212
+```
213
+
214
+### When Created
215
+1. **Before message editing** - When a user edits a message, all subsequent messages are removed
216
+2. **Before retry operations** - When retrying after an error, error and subsequent messages are removed
217
+
218
+### Visual Representation
219
+- Displayed as a horizontal line with token counts
220
+- Shows 💰 icon followed by cumulative tokens at that point
221
+- Includes the reason for the checkpoint
222
+
223
+### Impact on Cumulative Tokens
224
+The `getCumulativeTokenUsage()` function:
225
+1. Finds the last accounting node in the chat history
226
+2. Starts with its cumulative totals
227
+3. Adds only the token usage from messages after that accounting node
228
+4. This ensures the true total cost is always preserved
229
+
230
+### Important Notes
231
+- Accounting nodes are never sent to the LLM API
232
+- They only affect cumulative token display, not context window calculation
233
+- Multiple accounting nodes can exist in a chat history
234
+- They provide an audit trail of conversation edits and retries
235
+
236
+## Tool Memory - Rolling Window
237
+
238
+### Overview
239
+Tool Memory implements a rolling window for tool visibility. Tools and their responses are filtered based on how many "turns" have passed since they were used.
240
+
241
+### What is a Turn?
242
+A **turn** is a period of assistant activity that ends with a conclusion - an assistant message without tool calls. When the assistant sends a message without using tools, it marks the end of the current turn.
243
+
244
+### Configuration
245
+- `toolMemory.enabled`: Enable/disable the feature (default: false)
246
+- `toolMemory.forgetAfterConclusions`: Number of turns to keep tools visible (0-5, default: 1)
247
+
248
+### How It Works
249
+
250
+1. **Turn Tracking**: Each message is assigned to a turn number based on when it occurs
251
+2. **Turn Progression**: A new turn starts after the assistant concludes (sends a message without tools)
252
+3. **Filtering**: Tools are filtered if `(currentTurn - toolTurn) > forgetAfterConclusions`
253
+
254
+### Examples
255
+
256
+#### With `forgetAfterConclusions = 0` (immediate filtering):
257
+```
258
+Turn 0: Assistant uses tools A,B → concludes
259
+Turn 1: Assistant uses tools C,D → concludes
260
+Result: When in Turn 1, tools A,B are filtered (no longer visible)
261
+```
262
+
263
+#### With `forgetAfterConclusions = 1` (keep 1 turn):
264
+```
265
+Turn 0: Assistant uses tools A,B → concludes
266
+Turn 1: Assistant uses tools C,D → concludes
267
+Turn 2: Assistant uses tools E,F → concludes
268
+Result: When in Turn 2, tools A,B are filtered, but C,D are still visible
269
+```
270
+
271
+### Implementation Details
272
+
273
+1. **Two-Pass Processing**:
274
+ - First pass: Build the turn map by analyzing all messages
275
+ - Second pass: Filter messages based on turn age
276
+
277
+2. **Complete Filtering**:
278
+ - Tool response messages (`tool-results`) are removed entirely
279
+ - Tool calls in assistant messages (`tool_use` blocks) are also removed
280
+ - This prevents the assistant from seeing orphaned tool calls without responses
281
+
282
+3. **User Messages**:
283
+ - User messages don't create new turns
284
+ - They reset the "hasToolsInCurrentTurn" flag but preserve turn counting
285
+
286
+### UI Integration
287
+- Checkbox to enable/disable tool memory
288
+- Dropdown to select threshold (0-5 turns)
289
+- Tooltip shows human-readable text:
290
+ - 0 = "forget immediately"
291
+ - 1 = "forget after 1 turn"
292
+ - 2+ = "forget after N turns"
293
+ - Disabled = "Always remember"
294
+
295
+### Purpose
296
+This feature helps manage context window size and reduces costs by automatically removing old tool interactions that are no longer relevant to the current conversation flow.
297
+
298
+### Important: Mutual Exclusivity with Cache Control
299
+For Anthropic models, Tool Memory and Cache Control are mutually exclusive features:
300
+- When Tool Memory is enabled, Cache Control is automatically disabled
301
+- This prevents wasting money on caching content that will be filtered out
302
+- The cached content would include tools that Tool Memory removes in later turns
303
+- The UI enforces this by disabling the cache control option when tool memory is active

+### Managing Models
210
+
211
+#### Understanding Model Configuration
212
+
213
+**CRITICAL**: The proxy server enforces strict validation of all model configurations to prevent silent failures and ensure accurate cost tracking.
214
+
215
+The proxy server uses model information from two sources:
216
+
217
+1. **Configuration file** (`llm-proxy-config.json`):
218
+ - **This is the ONLY source of truth during runtime**
219
+ - Contains your API keys and active models
220
+ - You MUST add models here for them to be available
221
+ - You control all pricing and context window settings
222
+ - If a model is not in the config, it cannot be used
223
+ - **All models MUST pass strict validation or they will be rejected**
224
+
225
+2. **Built-in MODEL_DEFINITIONS** (in `llm-proxy.js`):
226
+ - Reference database of known models
227
+ - Used ONLY for configuration management (--show-models, --sync)
228
+ - Provides defaults when setting up new configurations
229
+ - NEVER used during normal proxy operation
230
+
231
+#### Strict Model Validation
232
+
233
+**NEW**: The proxy server now enforces strict validation of all model configurations. Models that don't meet the requirements are automatically rejected and will not be available for use.
234
+
235
+##### Validation Requirements by Provider
236
+
237
+Each provider has specific pricing field requirements:
238
+
239
+- **Google models**: Must have `input` and `output` pricing. Must NOT have `cacheRead` or `cacheWrite`.
240
+- **OpenAI models**: Must have `input`, `output`, and `cacheRead` pricing. Must NOT have `cacheWrite`.
241
+- **Anthropic models**: Must have all four pricing fields: `input`, `output`, `cacheRead`, and `cacheWrite`.
242
+
243
+All models must also have:
244
+- Valid `id` (string)
245
+- Valid `contextWindow` (positive number)
246
+- Valid `pricing` object with the required fields
247
+
248
+##### Validation Behavior
249
+
250
+- **At startup**: Invalid models are logged with specific error messages. Server continues with only valid models.
251
+- **During requests**: Requests to invalid models are rejected with HTTP 400 error.
252
+- **In API responses**: Only valid models are exposed via the `/models` endpoint.
253
+
254
+##### Example Validation Errors
255
+
256
+```
257
+❌ Configuration validation errors:
258
+ - openai model "gpt-4": Invalid pricing.cacheRead: must be a number >= 0
259
+ - google model "gemini-pro": Invalid pricing: Google models should not have cacheRead
260
+ - anthropic model "claude-3": Missing required fields (cacheWrite)
261
+```
262
+
263
+#### Using --show-models to Discover Changes
264
+
265
+The `--show-models` command helps you understand the state of your configuration:
266
+
267
+```bash
268
+node llm-proxy.js --show-models
269
+```
270
108
-## Proxy Endpoints
271
+Output shows a status column for each model:
272
+- **same**: Configuration matches built-in definitions
273
+- **different**: Configuration has different pricing or context window
274
+- **not in code**: Model exists in your config but not in built-in definitions (custom or deprecated)
275
+- **not in config**: Model exists in built-in definitions but not in your config (new model available)
276
+
277
+Example output:
278
+```
279
+🏢 OPENAI
280
+---------------------------------------------------
281
+Model ID Status Context Input $/MTok Output $/MTok

285
+gpt-4o-mini not in config 128000 $0.40 $1.60
286
+```
287
+
288
+#### Managing Models in Configuration
289
+
290
+##### Adding or Removing Models
291
+
292
+**IMPORTANT**: All models must follow the strict validation requirements listed above.
293
+
294
+Edit your configuration file to manage your models:
295
+
296
+```json
297
+{
298
+ "providers": {
299
+ "openai": {
300
+ "apiKey": "sk-...",
301
+ "models": [
302
+ {
303
+ "id": "gpt-4o",
304
+ "contextWindow": 128000,
305
+ "pricing": {
306
+ "input": 2.50, // Update when prices change
307
+ "output": 10.00,
308
+ "cacheRead": 0.625 // Required for OpenAI models
309
+ }
310
+ },
311
+ // Add new models here - must follow validation rules
312
+ {
313
+ "id": "my-custom-openai-model",
314
+ "contextWindow": 100000,
315
+ "pricing": {
316
+ "input": 5.00,
317
+ "output": 20.00,
318
+ "cacheRead": 5.00 // Required for OpenAI models
319
+ }
320
+ }
321
+ ]
322
+ }
323
+ }
324
+}
325
+```
326
+
327
+##### Updating Pricing
328
+
329
+When providers change their pricing:
330
+
331
+1. Edit the configuration file directly
332
+2. Update the `pricing` object for affected models
333
+3. Restart the proxy server
334
+4. All future accounting will use the new prices
335
+
336
+##### Using --sync (Optional)
337
+
338
+The `--sync` command overwrites your model list with built-in definitions:
339
+
340
+```bash
341
+node llm-proxy.js --update-config --sync
342
+```
343
+
344
+**Warning**: This will:
345
+- Replace ALL models with those from MODEL_DEFINITIONS
346
+- Reset any custom pricing you've configured
347
+- Remove any custom models you've added
348
+- Preserve only your API keys
349
+
350
+Use `--sync` only when you want to reset to defaults or after major updates.
351
+
352
+#### Model Discovery from Provider APIs
353
+
354
+For some providers, the proxy can fetch available models directly:
355
+
356
+- **OpenAI**: Fetches from `/v1/models` endpoint
357
+- **Google**: Fetches from `/v1/models` endpoint
358
+- **Anthropic**: No models endpoint available
359
+
360
+To check which models are actually available with your API key:
361
+```bash
362
+node llm-proxy.js --update-config --sync --check-availability
363
+```
364
+
365
+### Pricing Information
366
+
367
+#### How Pricing Works
368
+
369
+Model pricing is stored in the built-in MODEL_DEFINITIONS and includes:
370
+
371
+- **input**: Cost per million input tokens
372
+- **output**: Cost per million output tokens
373
+- **cacheRead**: Discounted rate for cached content (OpenAI/Anthropic)
374
+- **cacheWrite**: Additional cost for creating cache (Anthropic only, 25% surcharge)
375
+
376
+#### Pricing Sources
377
+
378
+All pricing in MODEL_DEFINITIONS is manually maintained based on official provider pricing:
379
+
380
+- **OpenAI**: https://openai.com/pricing
381
+- **Anthropic**: https://www.anthropic.com/pricing
382
+- **Google**: https://ai.google.dev/pricing
383
+
384
+**Note**: The proxy does NOT fetch pricing from provider APIs as this information is not available programmatically. Prices must be updated manually in the code when providers change their rates.
385
+
386
+#### Keeping Pricing Updated
387
+
388
+To ensure accurate cost tracking:
389
+
390
+1. Periodically check provider pricing pages for updates
391
+2. Edit your configuration file to update prices for affected models
392
+3. Restart the proxy server to load the new configuration
393
+
394
+The accounting logs ONLY use pricing from your configuration file. **With strict validation enabled, models without proper pricing information are automatically rejected and cannot be used.** This ensures you have full control and awareness of all pricing used in your system, and prevents requests to improperly configured models.
395
+
396
+### MCP Server Configuration
397
+
398
+You can configure default MCP servers that will be automatically available in the web client:
399
+
400
+```json
401
+{
402
+ "mcpServers": [
403
+ {
404
+ "id": "local_netdata",
405
+ "name": "Local Netdata",
406
+ "url": "ws://localhost:19999/mcp?api_key=YOUR_API_KEY"
407
+ },
408
+ {
409
+ "id": "remote_server",
410
+ "name": "Remote Server",
411
+ "url": "ws://remote.example.com:19999/mcp?api_key=YOUR_API_KEY"
412
+ }
413
+ ]
414
+}
415
+```
416
+
417
+- **id**: Unique identifier for the server (required)
418
+- **name**: Display name shown in the UI (required)
419
+- **url**: WebSocket URL for the MCP server (required)
420
+
421
+These servers will be automatically loaded when users access the web client. Users can still add additional servers through the UI, which are stored in their browser's localStorage.
422
+
423
+**Note**: If no MCP servers are configured, the proxy will automatically provide a default server pointing to `ws://localhost:19999/mcp` to ensure the web client can start properly. You'll need to configure the API key through the UI or add your own servers to the configuration.
424
+
425
+### API Endpoints
426

The proxy server provides:

15
+You are a helpful SRE/DevOps expert, and you are asked questions about some
16
+specific infrastructure, to which you have access via your tools.
17
+
18
+Always come up with a plan to provide holistic, accurate, and trustworthy
19
+answers, examining all the possible aspects of the question asked. Your answers
20
+MUST be concise, clear, and complete, as expected by a highly skilled and
21
+professional DevOps engineer.
22
+
23
+Your goal is to explain, educate and provide actionable insights, not just to
24
+answer questions. We help users understand their infrastructure, how it works,
25
+how to troubleshoot issues, how to identify root causes.
26
+
27
+**CRITICAL**:
28
+DO NOT EVER provide answers that are not based on data.
29
+
30
+**CRITICAL**:
31
+PROVIDE ACCURATE, COMPLETE, PROFESSIONAL AND TRUSTWORTHY ANSWERS!
32
+ALWAYS USE ALL THE TOOLS RELEVANT TO HELP YOU PROVIDE A COMPLETE ANSWER.
33
+
34
+## THINKING TAGS
35
+For ANY request involving data analysis, troubleshooting, or complex queries,
36
+you MUST use <thinking> tags to show your complete reasoning process.
37
+
38
+In your <thinking> section, always include:
39
+
40
+ - Your interpretation of the user's request and what they're trying to accomplish
41
+ - Your strategy for approaching the problem (which tools to use and why)
42
+ - Analysis of each piece of data you retrieve
43
+ - Connections you're making between different metrics/nodes/alerts
44
+ - Any assumptions or limitations in your analysis
45
+ - Your reasoning for conclusions or recommendations
46
+
47
+**CRITICAL**:
48
+Never skip the <thinking> section. Even for simple queries, show your reasoning
49
+process. This transparency helps users understand your analysis and methodology
50
+and builds confidence in your conclusions.
51
+
52
+## INVESTIGATION APPROACH
53
+
54
+**CRITICAL**: Tools are designed to be interactive. When they return errors
55
+requesting specific parameters, provide them and retry.
56
+
57
+Follow the data trail to build a complete picture:
58
+- Start with discovery tools to identify relevant components
59
+- Use outputs from one tool as inputs to others
60
+- When data reveals related areas worth investigating, explore them
61
+- Continue until you have sufficient information to answer comprehensively
62
+
63
+**CRITICAL**: Focus on providing data-driven insights. The tools are for your
64
+analysis - share conclusions with users, not tool execution details.
65
+
66
+## RECOMMENDATIONS
67
+ When you have a list of recommendation, make sure the use is not already
68
+ following them. For example, if you plan to recommend monitoring X, you
69
+ should first use your tools to verify they do not already monitor it.
70
+
71
+## FORMATTING GUIDELINES
72
+**CRITICAL**: Always use proper markdown formatting in your responses:
73
+
74
+- Use **bold** and *italic* for emphasis
75
+- Use proper markdown lists with dashes or numbers for structured information
76
+- For tree structures, node hierarchies, or ASCII diagrams, ALWAYS wrap them in
77
+ code blocks with triple backticks
78
+- Use inline code formatting for technical terms, commands, and values
79
+- Use > blockquotes for important notes or warnings
80
+- Use tables when presenting structured data
81
+- Use headings (##, ###) to organize your response
82
+- Use emojis sparingly to enhance readability, but do not overuse them
83
+
84
+## RESPONSE STYLE
85
+Be enthusiastic, helpful, educational, professional and friendly. Explain in
86
+detail what you see in the data, the patterns you observe, and the possible
87
+correlations. State only facts.
88
+
89
+## IRRELEVANT QUESTIONS
90
+If the user asks any question that is not relevant to DevOps/SRE/Sysadmin
91
+work, you MUST kindly reject it and focus on your PRIMARY GOAL: help them
92
+with their infrastructure problems.
93
+
94
+Common off-topic requests to reject:
95
+- Recipes, cooking, or food (e.g., "banana cake recipe")
96
+- General knowledge or trivia
97
+- Personal advice or life coaching
98
+- Creative writing or storytelling
99
+- Political or philosophical discussions
100
+- Comparisons with competitors (Datadog, New Relic, Grafana, etc.)

171
+
172
+IMPORTANT DATE/TIME INTERPRETATION RULES FOR MONITORING DATA:
173
+
174
+1. When the user mentions dates without a year (e.g., "January 15", "last month"), use ${currentDate.getFullYear()} as the current year
175
+2. When the user mentions times without a timezone (e.g., "10pm", "14:30"), assume ${timezoneInfo.name} timezone
176
+3. ALL relative references refer to the PAST (this is a monitoring system analyzing historical data):
177
+ - "this morning" = earlier today, before noon
178
+ - "this afternoon" = earlier today, after noon
179
+ - "tonight" = earlier today, evening hours
180
+ - "this Thursday" or "on Thursday" = the most recent Thursday (if today is Thursday and it's past the mentioned time, use today; otherwise use last Thursday)
181
+ - "during the weekend" = the most recent Saturday and Sunday
182
+ - "Monday" or "on Monday" = the most recent Monday
183
+4. IMPORTANT: Distinguish between complete time periods and relative offsets:
184
+ - "yesterday" = the complete 24-hour period before today at 00:00 (e.g., if today is Jan 15, yesterday is Jan 14 00:00 to Jan 14 23:59:59)
185
+ - "last week" = the complete previous calendar week (Monday 00:00 to Sunday 23:59:59)
186
+ - "last hour" = the complete previous clock hour (e.g., if it's 14:35, last hour is 13:00 to 13:59:59)
187
+ - "last month" = the complete previous calendar month (e.g., if it's January, last month is December 1-31)
188
+ - BUT: "7 days ago", "3 hours ago", "2 weeks ago" = exactly that amount of time before now
189
+5. Never interpret relative references as future times - users are always asking about historical monitoring data
190
+6. **CRITICAL**: Be careful with timezone conversions. If the user does not specify a timezone, assume they are expressing time at their local timezone.
191
+
192
+All date/time interpretations must be based on the current date/time context provided above, NOT on your training data.`;
