  • Create mastra-reference.md to document the Mastra backend structure, including agents, tools, networks, workflows, configuration, A2A coordination, MCP server, evaluations, services, data processing, and policy definitions.
  • Create reference.md to provide an extended reference for AI elements, agent configuration schema, and API routes for the dashboard, linking to the newly created mastra-reference.md.
  • Implement MainSidebar component in main-sidebar.tsx to enhance the user interface with navigation for agents, tools, workflows, and observability features.
    • Fetch and display agents, tools, workflows, traces, threads, and vector indices from the backend.
    • Include collapsible sections for better organization of sidebar items.
    • Add functionality to select agents and create new threads directly from the sidebar.

Summary by Sourcery

Add a primary AI dashboard sidebar and extend API/chat integrations with Mastra-aware streaming and multi-tenant support while documenting AI elements and Mastra backend structure.

New Features:

  • Introduce a MainSidebar layout for the chat page displaying agents, tools, workflows, traces, and vector indices with quick agent selection and thread creation.
  • Implement helper actions for creating, deleting, and updating memory threads and working memory, plus saving messages via MastraClient.
  • Extend the completion and chat-extra API routes to support dynamic agent selection, multi-tenant context (thread/resource IDs), and richer AI SDK streaming responses.

Enhancements:

  • Make sidebar data fetchers more robust to varying MastraClient response shapes for traces, threads, vectors, and logs.
  • Refactor the chat page layout to use a shared SidebarProvider and inset layout, integrating the new main sidebar alongside the existing chat sidebar.

Documentation:

  • Rewrite the AGENTS API documentation into a concise API routes reference covering core chat, contact, Mastra proxy, and observability endpoints.
  • Add detailed internal references for AI elements, AI SDK UI integration, and Mastra backend structure and routes under .agents/skills/ai-sdk-ui-master.

- Create `mastra-reference.md` to document the Mastra backend structure, including agents, tools, networks, workflows, configuration, A2A coordination, MCP server, evaluations, services, data processing, and policy definitions.
- Create `reference.md` to provide an extended reference for AI elements, agent configuration schema, and API routes for the dashboard, linking to the newly created `mastra-reference.md`.
- Implement `MainSidebar` component in `main-sidebar.tsx` to enhance the user interface with navigation for agents, tools, workflows, and observability features.
  - Fetch and display agents, tools, workflows, traces, threads, and vector indices from the backend.
  - Include collapsible sections for better organization of sidebar items.
  - Add functionality to select agents and create new threads directly from the sidebar.

File-Level Changes

Change Details Files
Document Mastra backend layout, AI elements, agent configuration, and API integration as internal skill/reference docs.
  • Add mastra-reference.md summarizing src/mastra agents, tools, networks, workflows, config, A2A, MCP, evals, services, data, and policy directories.
  • Add ai-elements-reference.md detailing base ai-elements, custom tool UIs, and their relationship to ui/ primitives and Mastra tools.
  • Add SKILL.md and reference.md describing the AI SDK UI Master skill, stack overview, transport patterns, and key integration points.
  • Wire these docs under .agents/skills/ai-sdk-ui-master/ for internal use.
.agents/skills/ai-sdk-ui-master/mastra-reference.md
.agents/skills/ai-sdk-ui-master/ai-elements-reference.md
.agents/skills/ai-sdk-ui-master/SKILL.md
.agents/skills/ai-sdk-ui-master/reference.md
Simplify and refocus AGENTS.md for app/api/ to describe concrete Mastra API endpoints and proxy routes.
  • Retitle document from Next.js API Routes to API Routes and update metadata.
  • Replace prior long-form patterns/best-practices section with a concise route catalog grouped by chat/AI, contact, Mastra proxy, threads, memory, tools, vectors, and observability.
  • Document MastraClient configuration, dependencies, env vars, file structure, and basic testing command.
  • Remove detailed Zod/type-safety, streaming patterns, and security examples in favor of route tables and key implementations.
app/api/AGENTS.md
Extend sidebar server actions to better support observability, memory/thread operations, and loosely-typed responses from MastraClient.
  • Harden fetchTraces and fetchThreads against different response shapes (traces vs spans; threads vs bare array) and avoid listing threads when resourceId is missing.
  • Tweak fetchVectors and fetchLogs mapping logic for clearer fallbacks and formatting.
  • Add new fetchProcessors, fetchScorers, createThread, deleteThread, updateWorkingMemory, and saveMessage helpers that wrap MastraClient and normalize success/error responses.
  • Remove the unused fetchMemoryStatus helper and SidebarMemoryStatus wiring.
app/chat/actions/sidebar-actions.ts
Replace simple completion and chat-extra API handlers with fully-featured streaming endpoints that support dynamic agent selection and multi-tenancy via RequestContext.
  • Update /api/completion to accept prompt, optional agentId/data/threadId/resourceId/memory, build a RequestContext with MASTRA_RESOURCE_ID_KEY and MASTRA_THREAD_ID_KEY, and stream via toAISdkStream into createUIMessageStreamResponse.
  • Update /api/chat-extra to mirror the main chat route semantics: dynamic agent selection based on data.agentId or id, RequestContext population, and robust handling of both ReadableStream and AsyncIterable from toAISdkStream.
  • Normalize UIMessage shapes (for completion) and ensure reasoning and sources are forwarded in the AI SDK stream options.
app/api/completion/route.ts
app/api/chat-extra/route.ts
Introduce a MainSidebar component and wrap the chat layout in the shared SidebarProvider to surface agents, resources, observability data, and thread creation from the main chat view.
  • Create MainSidebar client component that loads agents, tools, workflows, traces, threads, and vectors via sidebar server actions and renders them in collapsible Sidebar groups.
  • Wire MainSidebar into app/chat/page.tsx by wrapping the main content in SidebarProvider/SidebarInset, placing MainSidebar on the left and the existing ChatSidebar on the right.
  • Implement agent selection and new-thread behavior in MainSidebar using useChatContext, generateId, URL query updates, and a footer button to start a new thread with the currently selected agent.
  • Use @/ui/sidebar and @/ui/collapsible primitives plus lucide-react icons to match existing UI patterns; currently includes some duplicated groups (Resources/Observability) that may need consolidation on review.

Hey - I've found 1 issue, and left some high level feedback:

  • The new MainSidebar component duplicates entire sidebar groups (e.g. Resources and Observability sections appear twice with identical content); consider consolidating these to a single instance per section to simplify the UI and maintenance.
  • MainSidebar maintains networks and vectors state but never loads networks (no fetchNetworks call) and never renders vectors, so either wire these up to real data/sections or remove the unused state to avoid confusion.
  • In fetchThreads, the second parameter agentId is unused, and several new sidebar actions (createThread, deleteThread, updateWorkingMemory, saveMessage) hard-code defaults like 'default-resource'; either use the passed parameters consistently or remove them/defaults to avoid incorrect multi-tenancy behavior.
Prompt for AI Agents
Please address the comments from this code review:

## Overall Comments
- The new `MainSidebar` component duplicates entire sidebar groups (e.g. `Resources` and `Observability` sections appear twice with identical content); consider consolidating these to a single instance per section to simplify the UI and maintenance.
- `MainSidebar` maintains `networks` and `vectors` state but never loads networks (no `fetchNetworks` call) and never renders vectors, so either wire these up to real data/sections or remove the unused state to avoid confusion.
- In `fetchThreads`, the second parameter `agentId` is unused, and several new sidebar actions (`createThread`, `deleteThread`, `updateWorkingMemory`, `saveMessage`) hard-code defaults like `'default-resource'`; either use the passed parameters consistently or remove them/defaults to avoid incorrect multi-tenancy behavior.

## Individual Comments

### Comment 1
<location> `app/chat/components/main-sidebar.tsx:172-181` </location>
<code_context>
+                <SidebarGroup>
</code_context>

<issue_to_address>
**suggestion:** The `Resources` and `Observability` sections are duplicated, which complicates the UI and state.

There are two `Resources` groups (Workflows/Networks/Tools) and two `Observability` groups (Recent Traces). This duplication increases maintenance cost and risks the two copies diverging in behavior. Consider keeping a single instance of each or extracting them into reusable components instead of copy-pasting.

Suggested implementation:

```typescript
    const ResourcesSidebarGroup = () => (
        <SidebarGroup>
            <SidebarGroupLabel>Resources</SidebarGroupLabel>
            <SidebarGroupContent>
                <SidebarMenu>
                    <SidebarMenuItem>
                        <SidebarMenuButton asChild>
                            <Link href="/workflows">
                                <span>Workflows</span>
                            </Link>
                        </SidebarMenuButton>
                    </SidebarMenuItem>

Because I only see a small portion of the file, please:

1. Adjust the four SEARCH blocks that replace inline `Resources` / `Observability` groups so they match the exact JSX currently in your file. The important part is that you:
   - Move the **first** `Resources` group JSX into `ResourcesSidebarGroup`.
   - Move the **first** `Observability` group JSX into `ObservabilitySidebarGroup`.
2. Remove the duplicated second `Resources` and `Observability` groups and replace them with `<ResourcesSidebarGroup />` and `<ObservabilitySidebarGroup />` respectively, as shown.
3. Ensure `Link` is already imported (likely from `next/link`) at the top of the file; if your existing implementation uses a different navigation component or different hrefs, reuse those instead of the example hrefs I provided.

suggestion: The Resources and Observability sections are duplicated, which complicates the UI and state.

There are two Resources groups (Workflows/Networks/Tools) and two Observability groups (Recent Traces). This duplication increases maintenance cost and risks the two copies diverging in behavior. Consider keeping a single instance of each or extracting them into reusable components instead of copy-pasting.

Suggested implementation:

The networks state variable is defined but always remains empty because there's no corresponding fetch function call in the loadData useEffect. Either implement a fetchNetworks function and include it in the Promise.all, or remove the networks state and related UI sections if this functionality is not yet ready.

Suggested change
const [networks, setNetworks] = useState<any[]>([])

These storage JSON files are runtime artifacts from Mastra Crawlee that should not be committed to version control. According to .gitignore lines 143-148, files matching this pattern should already be ignored. These changes should be removed from the PR as they represent temporary runtime state, not source code changes.

The fetchThreads() call is made without the required resourceId parameter, which causes the function to always return an empty array (see sidebar-actions.ts line 152). This means threads will never be displayed in the sidebar even if they exist. Either pass a valid resourceId to fetchThreads() or remove the threads state and related UI if this functionality is not yet ready.

The "Resources" section (lines 234-318) and "Observability" section (lines 320-352) are duplicated identically at lines 354-438 and 440-472 respectively. This code duplication makes the component harder to maintain and increases the file size unnecessarily. Consider extracting these sections into reusable components or removing the duplicate sections entirely.

The "New Thread" button attempts to create a new thread for the currently selected agent, but if no agent is selected (selectedAgent is undefined or empty), this will fail or behave unexpectedly. Add a guard condition to disable the button or show an error when no agent is selected.

The agentId parameter is added to the function signature but never used in the implementation. Either utilize this parameter in the listMemoryThreads call (if supported by the API) or remove it from the function signature to avoid confusion.

Multiple uses of 'as any' type assertions throughout the file bypass TypeScript's type safety. This can hide potential runtime errors. Consider defining proper types for API responses or using more specific type guards to handle different response shapes safely.

Using Date.now() for message IDs can lead to collisions if multiple messages are created in rapid succession (within the same millisecond). Consider using a more robust ID generation method like crypto.randomUUID() or the generateId function from the 'ai' package that's already imported elsewhere in the codebase.

Remove this committed runtime state file from the repository.

This file is a Crawlee/Apify SessionPool state artifact that should never be committed. The path is already listed in .gitignore, but the file was committed anyway. Two issues apply:

  1. Session token leakage: The id fields (session_m2f8Zbu3Hq, etc.) are session identifiers. Once committed, they are permanently in git history even after expiry. Coding guidelines forbid tokens in code/files.
  2. Runtime state in version control: This state will diverge between environments and cause confusing merge conflicts.

Action: Use git rm --cached src/mastra/public/storage/key_value_stores/default/SDK_SESSION_POOL_STATE.json to remove the file from tracking. The .gitignore entry already prevents future commits of this path.

Duplicate MastraClient instantiation missing retry/backoff configuration.

A shared client already exists in lib/mastra-client.ts with retries: 3, backoffMs: 300, maxBackoffMs: 5000, an abort signal, and credentials: 'same-origin'. This local instance has none of those, degrading resilience for all sidebar actions. Import the shared client instead.

Proposed fix

67-92: 🧹 Nitpick | 🔵 Trivial

Pervasive as any / as unknown as Record<string, unknown> casts throughout the file.

Nearly every fetch function casts the API response through as any or as unknown as Record<string, unknown>, defeating TypeScript's safety. This is a systemic pattern across fetchAgents, fetchTools, fetchTraces, fetchThreads, fetchVectors, fetchLogs, fetchProcessors, and fetchScorers.

Consider creating a small set of type-narrowing helpers (e.g., isRecord(v): v is Record<string, unknown>) or defining expected response shapes from @mastra/client-js to reduce the any surface. As per coding guidelines, "Do not use implicit any types — use unknown or proper types instead".

  2. Line 156: (result as any).threads || (result as any) || [] — if result is a truthy non-array object (e.g. {}), the fallback resolves to that object and .map() on Line 157 will throw TypeError: threadsList.map is not a function.

markdownlint.

In `@app/api/chat-extra/route.ts`:
- Around line 1-93: This file duplicates agent selection
(agentId/mastra.getAgent), RequestContext setup (new RequestContext,
MASTRA_RESOURCE_ID_KEY/MASTRA_THREAD_ID_KEY and merging data), streamOptions
construction, and the ReadableStream/AsyncIterable bridge used inside
createUIMessageStream.execute; replace that duplicated logic by using the
reusable helper in lib/client-stream-to-ai-sdk.ts. Concretely: remove the inline
agent selection/RequestContext/streamOptions and the toAISdkStream
reader/for-await bridge inside POST, import and call the helper from
lib/client-stream-to-ai-sdk.ts (alongside
createUIMessageStream/createUIMessageStreamResponse) to obtain the ai-to-ui
streaming behavior, and keep POST focused on extracting body/messages and
passing agent, messages, and the constructed streamOptions to the helper; mirror
the same change in the other routes (app/api/chat/route.ts and
app/api/completion/route.ts) so all three reuse the helper.
- Around line 11-13: The POST handler currently calls await req.json() without
try/catch and destructures messages directly (used later as UIMessage[] for
agent.stream()), so add input validation: wrap req.json() in try/catch to handle
malformed JSON and validate the parsed body using a Zod schema (e.g., schema
with messages: array().min(1) and required fields id/data) and use
schema.safeParse to return a clear 400 error when validation fails; ensure you
only call agent.stream() with the validated messages array (not the raw cast
UIMessage[]) and return meaningful error responses on parse/validation failure.

In `@app/api/completion/route.ts`:
- Around line 86-98: The code uses "as any" to access getReader on aiStream and
to iterate, which bypasses typing; add a proper type-narrowing guard (e.g., an
isReadableStream(value: unknown): value is ReadableStream<Uint8Array> or
similar) that checks typeof value === 'object' && value !== null && typeof
(value as any).getReader === 'function', then treat aiStream under that guard as
a ReadableStream and call getReader without "as any"; likewise use a separate
guard like isAsyncIterable(value: unknown): value is AsyncIterable<Uint8Array>
(checking Symbol.asyncIterator in the value) before using for-await to avoid
implicit any and keep the reader/releaseLock and writer.write types correct
(reference symbols/idents: aiStream, getReader, reader, releaseLock, writer,
Symbol.asyncIterator).
- Around line 11-13: Wrap parsing of req.json() in a try/catch in the POST
handler and validate the extracted fields: ensure prompt is a string, trim it,
check it's non-empty and <= 10000 characters, and validate agentId/data shapes
as needed before proceeding; if validation fails return a 400 response with a
clear error message. After validation, use the sanitized prompt when
constructing the UIMessage (the value passed to agent.stream) to avoid undefined
messages. Ensure any parsing or runtime errors are caught and return a 500
response (or appropriate error) rather than allowing exceptions to bubble up.
- Around line 74-103: Wrap the agent.stream(...) call in a try/catch that logs
structured error details (include agentId from the current context,
error.message and error.stack) and returns/propagates a proper error UI response
instead of allowing an unhandled 500; then remove the inline
ReadableStream/AsyncIterable bridge in execute of createUIMessageStream and use
the shared helper from lib/client-stream-to-ai-sdk.ts (the function that
converts the model stream to the AI SDK stream) to consume the stream, passing
the original stream returned by agent.stream, so replace the custom loop around
toAISdkStream with the reusable bridge and ensure errors from the bridge are

fetchAgents, fetchTools, fetchWorkflows, fetchTraces, fetchThreads,
fetchVectors) to enable caching, automatic revalidation, retry on failure, and
centralized loading/error state, and expose a manual refresh/trigger
(mutate/refetch) that the sidebar UI can call; ensure you update state setters

consume the SWR/React Query results and remove the mount-only useEffect and
loadData.
- Around line 54-80: The PR contains dead code: remove or wire up the unused

integrate them into the component render by using NAV_ITEMS to generate the
sidebar links and replacing existing hardcoded nav markup with a map that calls
handleNavClick (or uses hrefs) and ensure the component imports/uses
WorkflowIcon, CpuIcon, ActivityIcon where needed so no referenced symbols remain
unused.
- Around line 82-133: MainSidebar is too large and mixes fetching/state with
rendering; extract the data-loading logic (current useEffect + loadData and
state variables agents, tools, workflows, traces, threads, vectors, loading,
error) into a custom hook (e.g., useSidebarData) that exposes {agents, tools,
workflows, traces, threads, vectors, loading, error, refetch} and move the
Promise.all calls/fetchAgents(), fetchTools(), fetchWorkflows(), fetchTraces(),
fetchThreads(), fetchVectors() into that hook (or replace with SWR/React Query
for caching/revalidation). Also extract repeated collapsible UI patterns from
MainSidebar into a presentational CollapsibleMenuSection component (used for
Agents, Tools, Workflows, Traces, Threads, Vectors) so MainSidebar only
orchestrates hook data, selection handlers (selectAgent, setThreadId) and
renders those components. Ensure unique symbols referenced are MainSidebar,
loadData/useEffect, useSidebarData, CollapsibleMenuSection, and the fetch*
functions when relocating behavior.
- Around line 475-490: The "New Thread" Footer button currently calls
handleAgentClick(selectedAgent) even when selectedAgent is empty; update the

SidebarMenuButton when selectedAgent is falsy so the click cannot fire;
reference SidebarMenuButton onClick, handleAgentClick, selectAgent, setThreadId,
and selectedAgent when making the change.

use the incoming transportId when provided (e.g. pass transportId ??
'MastraLogger') so callers' values are respected, and keep the existing fallback

modification.
- Around line 67-92: fetchAgents (and sibling functions like fetchTools,
fetchTraces, fetchThreads, fetchVectors, fetchLogs, fetchProcessors,
fetchScorers) currently force-unwrap API results using "as unknown as
Record<string, unknown>" which defeats TS safety; replace these casts by
declaring minimal response interfaces for the expected shapes (e.g., AgentRecord
with modelId|model|name|description) and/or add small type-narrowing helpers
(e.g., isRecord(v): v is Record<string, unknown>) and use them to safely extract
fields from the mastraClient.listAgents() return value inside fetchAgents (and
analogous code in the other fetch* functions) so you validate types at runtime
and remove all "as any"/"as unknown as Record..." casts.
- Around line 88-91: Replace all console.error usages in this file's catch
blocks with the structured log utility: import log from
"src/mastra/config/logger" at the top, then in each catch (for example in the
fetchAgents function and the other 13 catch blocks referenced) call log.error
with a clear message and the caught error object (e.g., log.error('fetchAgents
error', { error }) ), preserving the original return behavior; do this for every
catch block listed (lines around 88-91, 102-105, 116-119, 141-144, 163-166,

359-362).
- Around line 147-167: fetchThreads currently accepts an unused agentId and
unsafely falls back to a non-array result, causing .map to throw; update the
function to include agentId in the mastraClient.listMemoryThreads call when
provided (e.g., pass { resourceId, agentId } or only include agentId if defined)
and replace the unsafe fallback with a robust array check such as: const
threadsList = Array.isArray((result as any).threads) ? (result as any).threads :
Array.isArray(result) ? (result as any) : []; then continue mapping as before so
.map is only called on an actual array.

⚠️ Potential issue | 🟡 Minor

Broken markdown table: header row has 4 columns but separator row has only 3.

Line 209 defines a 4-column header (File | Exports | Purpose | Section), but the separator on Line 211 only has 3 columns. This causes the table to render incorrectly in most markdown parsers — the Section column data on lines 214, 221–223 will be silently dropped or misaligned.

Proposed fix

Also, Line 133 has 4 pipe-separated cells but the table header at Line 128 only has 3 columns. Either add a 4th header column or move the trailing comment out of the table cell:

Remove informal developer note from reference documentation.

Line 115 contains a casual comment ("This will only display weatherAgent so this is kinda useless since my mastra/index uses :agentid…") that doesn't belong in reference documentation. It's also inaccurate — the actual app/api/chat/route.ts implementation (shown in the relevant snippets) does implement dynamic agent selection via data?.agentId ?? id ?? 'weatherAgent'.

Replace it with a concise, accurate comment or remove it entirely.

🧹 Nitpick | 🔵 Trivial

Data fetched on mount only — sidebar never refreshes.

All six fetch calls run once on mount (empty dependency array). If agents, workflows, or traces change during the session (or if a network error occurs on initial load), the sidebar shows stale or empty data indefinitely. Consider using SWR/React Query for automatic revalidation, or at minimum expose a manual refresh mechanism.

As per coding guidelines, "Use SWR or React Query for client-side data fetching and caching".

Resources and Observability sections are fully duplicated — likely a copy-paste bug.

Lines 234–352 (Resources group with Workflows/Networks/Tools + Observability group with Recent Traces) are repeated verbatim at lines 354–472. This renders two identical sidebar sections to the user.

Remove the duplicate block (either lines 234–352 or lines 354–472).

⚠️ Potential issue | 🟡 Minor

Footer "New Thread" button may fire with an empty selectedAgent.

If no agent has been selected yet, selectedAgent could be an empty string or a default value. handleAgentClick('') would call selectAgent('') and setThreadId(...) with no valid agent, leading to an invalid URL /chat?agent=.

Code Review

This pull request introduces extensive documentation for the AI SDK UI and Mastra backend, which is a great addition for developers. It also adds a new main sidebar component to improve navigation and user experience. My review focuses on several areas for improvement. I've identified some issues in the new main-sidebar.tsx component, including duplicated UI elements and missing data fetching for networks, which should be addressed. There's also some code duplication in the API routes (chat-extra and completion) that could be refactored for better maintainability. Additionally, I've found some minor issues in the new documentation files and action handlers, such as developer comments, magic numbers, and unused parameters. Addressing these points will enhance the quality and robustness of the new features.

The networks state is initialized but is never populated with data, as there is no corresponding fetch call in the loadData function. This causes the 'Networks' section in the sidebar to always be empty. The data fetching for networks should be implemented.

There is a duplicated block of UI code. The SidebarGroup for 'Resources' and 'Observability' is rendered twice. This appears to be a copy-paste error and the second block should be removed to fix the UI.

The markdown table header is broken here, with the header row split across two lines. Additionally, the last column contains informal notes like **This is for Web** and **This is for Coding** which should be integrated into the 'Purpose' column for better clarity and a more consistent documentation style.

This API route handler duplicates a significant amount of logic for creating a streaming response, which is also present in other routes like app/api/chat/route.ts. To improve maintainability and reduce redundancy, this logic should be extracted into a shared helper function. The project's documentation already suggests using a helper like createAgentStreamResponse for this purpose.

This route handler reimplements complex streaming logic, which is also found in other API routes. This code duplication increases the maintenance burden. It is recommended to refactor this to use a centralized helper function for creating streaming responses, as suggested in the project's documentation, to ensure consistency and simplify future updates.

The fetchThreads function accepts an agentId parameter that is not used within the function's body. This can be misleading for developers. If the parameter is intended for future use, a // TODO comment would be helpful. Otherwise, it should be removed to clean up the function signature.

The string 'default-resource' is hardcoded as a fallback resourceId in createThread, updateWorkingMemory (line 330), and saveMessage (line 350). Using hardcoded magic strings makes the code harder to maintain and update. This value should be extracted into a named constant and reused across these functions.

The format property of a message is assigned a fallback value of 2. This magic number lacks context and makes the code harder to understand. To improve readability and maintainability, it should be replaced with a named constant or an enum that describes its meaning (e.g., MESSAGE_FORMAT_V2).

The NAV_ITEMS constant and the associated handleNavClick function (lines 155-159) are defined but are not used anywhere in the component. This unused code should be removed to improve code clarity and maintainability.
