feat: provider selection flows + command UI

[Aditya190803]

This pull request introduces major enhancements to the CLI, agent prompt construction, and provider management for finance and web search. The update adds interactive slash commands, improves context selection for agent prompts, and introduces a flexible provider abstraction layer with automatic failover support.

It also updates documentation and environment configuration to support Alpha Vantage as an alternative finance data provider.

Key Changes

CLI Enhancements

• Added slash commands for session and provider management:
  • /help
  • /new
  • /model
  • /finance
  • /search
  • /web-search
• Added text commands:
  • exit
  • quit
• Implemented command registry with structured help output.
• Added slash command suggestions and autocomplete in the input field.
• Improved input handling:
  • Shift + Enter for new lines
  • Ctrl + Backspace for word deletion
• Displayed currently selected finance and web search providers in the main CLI UI.

Provider Selection & Abstraction

• Introduced provider abstraction layer for:
  • Finance data providers
  • Web search providers
• Added automatic provider failover support.
• Implemented interactive CLI flows for:
  • /finance provider selection
  • /search and /web-search provider selection
• Added API key confirmation and input handling within CLI flows.
• Created provider selector components and supporting hooks.
• Exported provider utilities for reuse.

Agent Improvements

• Refactored agent prompt construction:
  • Asynchronous selection of relevant prior context.
  • Uses completed messages and relevance filtering.
• Improved browser context handling (Playwright).
• Resolved agent and browser context issues.

Finance API & Tooling Updates

• Expanded finance API support.
• Updated tool registry to integrate new providers.
• Improved long-term chat history handling.

Documentation & Environment Updates

• Updated README.md with:
  • Alpha Vantage support as an alternative to Financial Datasets.
  • Clearer provider configuration instructions.
• Updated environment configuration files to support new provider setup.

UI Improvements

• Removed spinner from agent event views to streamline UI feedback during:
  • Tool execution
  • Browser sessions

Pull request overview

This PR adds provider abstraction and selection flows for finance and web search tools, along with a command registry system for the CLI. However, the implementation is incomplete with critical non-functional stub components and hooks that will cause runtime errors.

Changes:

• Adds provider abstraction for finance (Financial Datasets, Alpha Vantage) and web search (Exa, LangSearch, Tavily) with automatic failover based on available API keys
• Implements Alpha Vantage as an alternative finance data provider with comprehensive endpoint mapping
• Adds LangSearch as a new web search provider option
• Introduces command registry with /help, /new, /finance, /search commands and autocomplete support
• Improves agent context initialization to use relevant message selection from chat history
• Fixes browser context handling to properly manage Playwright browser and context lifecycle
• Adds clear functionality to input history and agent runner
• Removes visual effects (shine animation, spinners) from UI components

The financeProvider value comes from useFinanceSelection hook which returns null as any (line 80). When this null value is passed to getFinanceProviderDisplayName at line 383, it will cause an error because getFinanceProviderDisplayName expects a valid FinanceProviderId but doesn't handle null. The function will try to call getFinanceProviderDef with null, which will throw "Unknown finance provider: null". The display name functions need null-safe handling, or the stub hooks need to return a default value like 'auto' instead of null.

Suggested change

	Finance: <Text color={colors.primary}>{getFinanceProviderDisplayName(financeProvider)}</Text>
	Finance:{' '}
	<Text color={colors.primary}>
	{financeProvider ? getFinanceProviderDisplayName(financeProvider) : 'Auto'}

The function will try to call getWebSearchProviderDef with null, which will throw "Unknown web search provider: null".

This hook is a non-functional stub implementation. All methods return empty functions or null values, which means the web search provider selection flow in the CLI will not work. The hook is being called in src/cli.tsx (line 64-75) and its methods are used throughout the CLI, but they don't perform any actual logic. This needs to be implemented following the pattern used in useModelSelection to properly handle provider selection, API key validation, and configuration persistence.

This component is a non-functional stub that only renders a title. It's being used in src/cli.tsx (lines 311-314) when the user selects the /search command, but it doesn't provide any interactive UI for selecting a web search provider. This needs to be implemented following the pattern of ProviderSelector in ModelSelector.tsx, showing a list of available providers (from WEB_SEARCH_PROVIDER_DEFS), allowing keyboard navigation, and calling onSelect when the user makes a choice.

This help text on line 45 is excessively long and difficult to read as a single line. Consider splitting it into multiple lines or simplifying the message to just mention "/help for commands" since that will show all available commands including /model, /finance, and /search.

The reassignment of context at line 201 is unnecessary and potentially confusing. The ensureBrowser() function at line 199 already ensures that the module-level context variable is initialized (see lines 37-39 in ensureBrowser). The fallback context ?? currentPage.context() at line 200 will always use the already-initialized context. This line should be simplified to just use context directly, or the entire lines 200-201 can be removed and context used directly at line 202.

Suggested change

	const newContext = context ?? currentPage.context();
	context = newContext;
	const newPage = await newContext.newPage();

The wrapIndex function is duplicated across multiple components (Input.tsx, FinanceProviderSelector.tsx, WebSearchProviderSelector.tsx, and ModelSelector.tsx). Consider extracting this utility function to a shared location to reduce code duplication and improve maintainability.

Missing test case for when no API keys are configured. The resolveWebSearchProvider function returns null when no provider keys exist, but this scenario is not tested. Consider adding a test case like:

it('returns null when no provider key exists', () => {
  const resolved = resolveWebSearchProvider('auto', {
    EXASEARCH_API_KEY: '',
    LANGSEARCH_API_KEY: '',
    TAVILY_API_KEY: '',
  });
  expect(resolved).toBeNull();
});

The 'close' event listener is attached every time a new page is created in ensureBrowser, but there's no cleanup of the previous listener when a page is replaced. This could lead to multiple listeners being attached to different page instances. Consider using page.once('close', ...) instead of page.on('close', ...) to ensure the listener is only triggered once, or track if the listener has already been attached.

Suggested change

	page.on('close', () => {
	page.once('close', () => {

callApi reads/writes the local cache before resolving which finance provider is active, and the cache key only includes endpoint + params. If the user switches providers (Financial Datasets ↔ Alpha Vantage), the same endpoint/params can return cached data from the other provider, producing incorrect results. Include the resolved provider in the cache key (e.g., prefix the endpoint with the provider ID or add a provider field to the params used for caching) and only read from cache after provider resolution.

These new imports omit the .js extension (./hooks/useWebSearchSelection / ./hooks/useFinanceSelection) while the rest of the ESM imports in this file use explicit .js. This can break runtime resolution after TypeScript emits JS (Node ESM typically won’t resolve extensionless paths). Update the import specifiers to include .js for consistency and runtime safety.

Suggested change

	import { useWebSearchSelection } from './hooks/useWebSearchSelection';
	import { useFinanceSelection } from './hooks/useFinanceSelection';
	import { useWebSearchSelection } from './hooks/useWebSearchSelection.js';
	import { useFinanceSelection } from './hooks/useFinanceSelection.js';

In the open action, a new page is created via context!.newPage() and assigned to the module-level page, but it does not register the same page.once('close', ...) handler used in ensureBrowser(). If this new page is closed later, page and currentRefs may become stale until the next ensureBrowser() call. Attach the close handler (and consider avoiding the non-null assertion by ensuring context is available locally) when creating newPage.

resolvedProvider can be null when no finance provider key is configured, but this branch throws a provider-specific message (“only supported with Financial Datasets”) that’s misleading in that case. Handle null separately (e.g., prompt to configure a provider/API key) and keep the current error for the Alpha Vantage case.

Suggested change

	if (!resolvedProvider) {
	throw new Error(
	'No finance provider is configured. Please configure a finance provider/API key to use filing item types.',
	);
	}

wrapIndex doesn't correctly wrap indices less than -length. In JS, % keeps the sign, so e.g. wrapIndex(-6, 5) returns -1. Consider using a true modulo normalization (e.g. ((index % length) + length) % length) so the result is always in [0, length) for any integer index.

Suggested change

	return (index + length) % length;
	return ((index % length) + length) % length;

Using providerScopedEndpoint = ${resolvedProvider}:${endpoint}`` will feed a string containing : into `buildCacheKey()`. That `:` becomes part of the cache path (see `cleanEndpoint` logic), which can break on Windows filesystems where `:` is not allowed in filenames. Prefer encoding the provider without `:` (e.g. `${resolvedProvider}${endpoint}` or `${resolvedProvider}/${endpoint}`) or otherwise sanitizing the provider prefix before passing it to the cache layer.

Suggested change

	const providerScopedEndpoint = `${resolvedProvider}:${endpoint}`;
	const providerScopedEndpoint = `${resolvedProvider}_${endpoint}`;

This change adds substantial new behavior (provider selection + Alpha Vantage endpoint mapping + new filtering/normalization logic) but there are no unit tests covering callApi() routing/caching behavior or the Alpha Vantage response normalization. Given the existing Bun test setup (e.g. cache/providers tests), please add tests that mock fetch to validate key endpoints (prices snapshot, prices range/year grouping, financial metrics, error handling) and ensure caching keys remain stable across providers.
