From 9fb348b12354ba6723b23ff7d92efc2a38c038a2 Mon Sep 17 00:00:00 2001 From: deseltrus <101901449+deseltrus@users.noreply.github.com> Date: Thu, 12 Mar 2026 14:12:19 +0100 Subject: [PATCH] feat: add Tavily as alternative search provider (#102) Add Tavily Search API as an alternative backend for search-the-web and search_and_read tools. Tavily is selected automatically when TAVILY_API_KEY is set (preferred over Brave when both keys present). Existing Brave Search paths are completely unchanged. Motivation: Brave Search API signup requires Stripe payment which may not be available in all regions. Tavily offers a free tier and also provides a Deep Research API for future expansion. Changes: - Auth: Tavily API key in wizard, auth.json storage, env hydration - search-the-web: Tavily POST backend with response normalization - search_and_read: Tavily advanced search with client-side token budgeting - /search-provider: slash command for explicit provider switching - 61 new tests covering all Tavily integration paths - Zero changes to existing Brave code paths --- .../extensions/gsd/tests/resolve-ts-hooks.mjs | 29 +- .../search-the-web/command-search-provider.ts | 95 +++++ .../extensions/search-the-web/http.ts | 2 +- .../extensions/search-the-web/index.ts | 12 +- .../extensions/search-the-web/provider.ts | 118 ++++++ .../extensions/search-the-web/tavily.ts | 116 ++++++ .../search-the-web/tool-llm-context.ts | 387 ++++++++++++------ .../extensions/search-the-web/tool-search.ts | 249 +++++++---- src/tests/app-smoke.test.ts | 58 +-- src/tests/llm-context-tavily.test.ts | 372 +++++++++++++++++ src/tests/provider.test.ts | 275 +++++++++++++ src/tests/search-provider-command.test.ts | 372 +++++++++++++++++ src/tests/search-tavily.test.ts | 358 ++++++++++++++++ src/tests/tavily-helpers.test.ts | 180 ++++++++ src/wizard.ts | 8 + 15 files changed, 2366 insertions(+), 265 deletions(-) create mode 100644 src/resources/extensions/search-the-web/command-search-provider.ts create mode 100644 src/resources/extensions/search-the-web/provider.ts create mode 100644 src/resources/extensions/search-the-web/tavily.ts create mode 100644 src/tests/llm-context-tavily.test.ts create mode 100644 src/tests/provider.test.ts create mode 100644 src/tests/search-provider-command.test.ts create mode 100644 src/tests/search-tavily.test.ts create mode 100644 src/tests/tavily-helpers.test.ts diff --git a/src/resources/extensions/gsd/tests/resolve-ts-hooks.mjs b/src/resources/extensions/gsd/tests/resolve-ts-hooks.mjs index f3e1cd668..9740c9344 100644 --- a/src/resources/extensions/gsd/tests/resolve-ts-hooks.mjs +++ b/src/resources/extensions/gsd/tests/resolve-ts-hooks.mjs @@ -1,17 +1,34 @@ // ESM resolve hook: .js → .ts rewriting for test environments. // Only rewrites relative imports from our own source files — not from node_modules. +// +// Handles two patterns: +// 1. .js → .ts (pi bundler convention: source files use .js specifiers) +// 2. extensionless → .ts (some source files omit extensions in relative imports) export function resolve(specifier, context, nextResolve) { const parentURL = context.parentURL || ''; const isFromNodeModules = parentURL.includes('/node_modules/'); - if (specifier.endsWith('.js') && !specifier.startsWith('node:') && !isFromNodeModules) { - const tsSpecifier = specifier.replace(/\.js$/, '.ts'); - try { - return nextResolve(tsSpecifier, context); - } catch { - // fall through to default resolution + if (!isFromNodeModules && !specifier.startsWith('node:')) { + // Rewrite .js → .ts + if (specifier.endsWith('.js')) { + const tsSpecifier = specifier.replace(/\.js$/, '.ts'); + try { + return nextResolve(tsSpecifier, context); + } catch { + // fall through to default resolution + } + } + + // Try adding .ts to extensionless relative imports + if (specifier.startsWith('.') && !/\.[a-z]+$/i.test(specifier)) { + try { + return nextResolve(specifier + '.ts', context); + } catch { + // fall through to default resolution + } } } + return nextResolve(specifier, context); } diff --git a/src/resources/extensions/search-the-web/command-search-provider.ts b/src/resources/extensions/search-the-web/command-search-provider.ts new file mode 100644 index 000000000..880910733 --- /dev/null +++ b/src/resources/extensions/search-the-web/command-search-provider.ts @@ -0,0 +1,95 @@ +/** + * /search-provider slash command. + * + * Lets users switch between tavily, brave, and auto search backends. + * Supports direct arg (`/search-provider tavily`) or interactive select UI. + * Tab completion provides the three valid options with key status. + * + * All provider logic lives in provider.ts (S01) — this is pure UI wiring. + */ + +import type { ExtensionAPI } from '@mariozechner/pi-coding-agent' +import type { AutocompleteItem } from '@mariozechner/pi-tui' +import { + getTavilyApiKey, + getBraveApiKey, + getSearchProviderPreference, + setSearchProviderPreference, + resolveSearchProvider, + type SearchProviderPreference, +} from './provider.ts' + +const VALID_PREFERENCES: SearchProviderPreference[] = ['tavily', 'brave', 'auto'] + +function keyStatus(provider: 'tavily' | 'brave'): string { + if (provider === 'tavily') return getTavilyApiKey() ?
