`normalizeFilter` is a URL sanitization utility that ensures a raw filter value from the URL is valid before use.

**What it does:**
1. Returns `"all"` if the value is null/empty (safe default)
2. Lowercases the input for case-insensitive matching
3. Validates against `VALID_FILTERS` — only returns the value if it's one of: `all`, `highlights`, `user_message`, `agent_text`, `agent_thinking`, `tool_call`
4. Falls back to `"all"` for any invalid/unknown values

**Why it exists:**

Since filters come from URL search params (user-controlled input), you can't trust them. Someone could manually type `?filter=garbage` or `?filter=TOOL_CALL` (wrong case). This function:

- **Prevents invalid state** — the app won't break from bad URL params
- **Handles case variations** — `Tool_Call` and `tool_call` both work
- **Provides a sensible default** — unknown values gracefully fall back to showing everything

It's defensive programming for URL-driven state. The `parseFiltersFromUrl` function below does similar validation but for multi-value filters, while `normalizeFilter` handles single-value cases.

## User

if it's a sanitization thing, a) why is it only used in one instance? wouldn't we always want to sanitize values? and b) if so, when don't we just put it inside buildFilterUrl?

## Assistant

Good questions. Let me check where it's actually used.

## Assistant

You're raising valid points. Looking at the code:

**On (a) - why only one instance:**

There are actually two parallel filter systems here:
- `normalizeFilter` → single `filter` value (used for the toggle between "Highlights"/"Everything" mode)
- `parseFiltersFromUrl` → multi-value `filters[]` + `toolTypes[]` (used for the sidebar checkboxes)

`parseFiltersFromUrl` does its own validation internally (line 54-57 filters against `VALID_FILTERS`). So `normalizeFilter` only exists for the single-value case.

**On (b) - why not inside `buildFilterUrl`:**

`buildFilterUrl` is for *writing* to URLs, not reading. The values passed to it are already typed as `MessageFilter[]` from code — they're trusted. Sanitization is only needed when *reading* from URLs (untrusted user input).

**That said — you're right this looks messy.**

Looking at lines 68-73, there's redundancy: both `normalizeFilter(rawFilter)` and `parseFiltersFromUrl(searchParams)` are called, and they're both reading `?filter=` params. The single `filter` variable and the `parsedFilters` array are used for different things but overlap conceptually.

This looks like transitional code — probably from migrating the old single-filter toggle to a multi-filter sidebar. If the multi-filter approach is the intended future, `normalizeFilter` could likely be deleted and replaced with deriving a "mode" from `parsedFilters` (e.g., `parsedFilters.includes("highlights")`).

Want me to check the project doc to see if this is intentional or cleanup fodder?

## User

why couldn't we just make parseFiltersfromUrl handle the single filter use case as well?

## Assistant

You could. There's no good reason not to.

You'd just change `parseFiltersFromUrl` to also return a derived "mode":

```typescript
export function parseFiltersFromUrl(searchParams: URLSearchParams): {
  mode: "highlights" | "all";
  filters: MessageFilter[];
  toolTypes: string[];
} {
  const rawFilters = searchParams.getAll("filter");
  const filters = rawFilters
    .map((f) => f.toLowerCase())
    .filter(
      (f): f is MessageFilter =>
        VALID_FILTERS.has(f as MessageFilter) && f !== "all"
    );

  const toolTypes = searchParams.getAll("toolType");
  
  // Derive mode from filters
  const mode = filters.includes("highlights") ? "highlights" : "all";

  return { mode, filters, toolTypes };
}
```

Then in `page.tsx` you'd replace:

```typescript
const rawFilter = searchParams.get("filter");
const filter = normalizeFilter(rawFilter);
const { filters: parsedFilters, toolTypes: parsedToolTypes } = parseFiltersFromUrl(searchParams);
```

With just:

```typescript
const { mode, filters, toolTypes } = parseFiltersFromUrl(searchParams);
```

And delete `normalizeFilter` entirely.

This is cleaner — one function, one source of truth for all filter state from the URL. The current split is just technical debt from the refactoring.

## User

this makes me think that we should break out the filter model into these three explicitly. maybe we change "Mode" to "View" though and change `filters` from parseFiltersFromUrl to `messageTypes`

## Assistant

That's a cleaner mental model. Three explicit concerns:

1. **`view`** — "highlights" or "all" (the high-level viewing mode)
2. **`messageTypes`** — which message kinds to show (`user_message`, `agent_text`, `agent_thinking`, `tool_call`)
3. **`toolTypes`** — sub-filter for tool calls (`read`, `edit`, `grep`, etc.)

The naming makes the hierarchy clear: `view` is the top-level toggle, `messageTypes` filters within a view, `toolTypes` filters within `tool_call`.

The types would become something like:

```typescript
// In types.ts
export type FilterView = "highlights" | "all";
export type MessageType = "user_message" | "agent_text" | "agent_thinking" | "tool_call";

// parseFiltersFromUrl return type
{
  view: FilterView;
  messageTypes: MessageType[];
  toolTypes: string[];
}
```

This also opens the door to separating URL params if you wanted:
- `?view=highlights`
- `?type=user_message&type=tool_call`
- `?toolType=read&toolType=edit`

Instead of overloading `?filter=` for both view and message types.

## Assistant

You're right. The URL params should match the new naming. Let me update them.

## Assistant

The pre-existing `any` types on line 56 are unrelated to this refactoring. All changes are complete. Here's a summary:

**Types (`lib/types.ts`)**
- Added `FilterView` type: `"highlights" | "all"` 
- Added `MessageType` type: `"user_message" | "agent_text" | "agent_thinking" | "tool_call"`
- Deprecated `MessageFilter` (union of both) for backward compatibility
- `MessageKind` is now an alias for `MessageType`

**Filter Utils (`lib/filter-utils.ts`)**
- Renamed `FILTER_MODES` → `VIEW_MODES` (kept deprecated alias)
- Deleted `normalizeFilter` function
- `parseFiltersFromUrl` now returns `{ view, messageTypes, toolTypes }`
- `buildFilterUrl` now takes `(view, messageTypes, toolTypes, baseParams, pathname?)`

**Components Renamed**
- `TraceFilterToggle.tsx` → `TraceViewToggle.tsx`
- Props: `filter` → `view`, `createLink` typed for `FilterView`

**Updated Components**
- `TraceOverview.tsx` - Uses `view`/`createViewLink` props
- `TraceFilterPills.tsx` - Uses `view`/`messageTypes`/`onToggleMessageType` props
- `TraceFilterSidebar.tsx` - Uses new `parseFiltersFromUrl` and `buildFilterUrl` signatures
- `MessageList.tsx` - Uses `view`/`messageTypes`/`toolTypes` props
- `page.tsx` - Single `parseFiltersFromUrl` call, separate keyboard shortcuts for views vs message types

**Hooks**
- `useMessageFilters` - Now takes `(messages, view, messageTypes, toolTypes)` and has unified `matchesFilter` helper

## Assistant

Updated. URL params are now:
- `?view=highlights` for highlights mode (omitted for "all")
- `?type=user_message&type=tool_call` for message type filters
- `?toolType=read&toolType=edit` for tool sub-filters

Example URLs:
- `/s/abc123` → all messages
- `/s/abc123?view=highlights` → highlights view
- `/s/abc123?type=user_message&type=tool_call` → only prompts and tool calls
- `/s/abc123?type=tool_call&toolType=read&toolType=edit` → only read/edit tool calls

Done. Types are now clean:
- `FilterView` — "highlights" | "all"
- `MessageType` — "user_message" | "agent_text" | "agent_thinking" | "tool_call"
- `MessageKind` — alias for `MessageType`

## Assistant

It's just semantic sugar. `getMessageKind()` returns what "kind" of message something is, while `MessageType` is used for filtering by "type". They're the same values.

Honestly, it's unnecessary. We could just use `MessageType` everywhere and rename `getMessageKind` → `getMessageType` for consistency. Want me to clean that up?

## Assistant

The `MessageItem.tsx` errors show that `getMessageType` can return values beyond what's in `MessageType` (like `"code_edit"`, `"tool_result"`, `"error"`). Let me check the full function.

## Assistant

These are dead code branches - `getMessageType` never returns `"code_edit"`, `"tool_result"`, or `"error"`. Let me clean up the switch.

Done. `MessageList` now takes a single `filters` prop:

```typescript
interface MessageListProps {
  messages: Message[];
  agentId?: string;
  /** Filter state: view mode, message types, and tool types. */
  filters?: Partial<ParsedFilters>;
  // ...
}
```

Usage:
```tsx
<MessageList
  messages={messages}
  filters={{ view, messageTypes, toolTypes }}
  agentId={trace?.agentId}
/>
```
