What this skill does
# Speak Hello World
## Overview
Create your first AI tutoring session with Speak. Demonstrates conversation practice, pronunciation assessment, and real-time feedback using GPT-4o-powered tutoring.
## Prerequisites
- Completed `speak-install-auth` setup
- Valid API credentials configured
- Microphone access (optional for testing)
## Instructions
### Step 1: Start a Conversation Session
```typescript
import { SpeakClient } from '@speak/language-sdk';
const client = new SpeakClient({
apiKey: process.env.SPEAK_API_KEY!,
appId: process.env.SPEAK_APP_ID!,
language: 'es',
});
// Start a beginner Spanish lesson
const session = await client.startConversation({
scenario: 'greetings',
language: 'es',
level: 'beginner',
nativeLanguage: 'en',
});
console.log('Session ID:', session.id);
console.log('AI Tutor:', session.firstPrompt.text);
// Output: "Hola! Bienvenido a tu leccion de espanol. Como te llamas?"
console.log('Audio URL:', session.firstPrompt.audioUrl);
```
### Step 2: Send a Student Response
```typescript
// Submit text response (or audio file for pronunciation scoring)
const turn = await client.sendTurn(session.id, {
text: 'Hola, me llamo Juan. Mucho gusto.',
// Or: audioPath: './recordings/response.wav'
});
console.log('Tutor response:', turn.tutorText);
console.log('Pronunciation score:', turn.pronunciationScore); // 0-100
console.log('Grammar corrections:', turn.corrections);
// Output: [{original: "me llamo", suggestion: null, correct: true}]
console.log('Vocabulary notes:', turn.vocabularyNotes);
```
### Step 3: Pronunciation Assessment
```typescript
// Assess pronunciation of a specific phrase
const assessment = await client.assessPronunciation({
audioPath: './recordings/hola-como-estas.wav',
targetText: 'Hola, como estas?',
language: 'es',
detailLevel: 'phoneme', // 'word' or 'phoneme'
});
console.log(`Overall score: ${assessment.score}/100`);
for (const word of assessment.words) {
console.log(` "${word.text}": ${word.score}/100`);
if (word.phonemes) {
for (const p of word.phonemes.filter(p => p.score < 70)) {
console.log(` Weak phoneme: ${p.symbol} (${p.score}) - ${p.suggestion}`);
}
}
}
```
### Step 4: End Session and Review
```typescript
const summary = await client.endSession(session.id);
console.log('Session Summary:');
console.log(` Duration: ${summary.durationMinutes} min`);
console.log(` Turns: ${summary.totalTurns}`);
console.log(` Pronunciation: ${summary.avgPronunciationScore}/100`);
console.log(` Grammar: ${summary.grammarAccuracy}%`);
console.log(` New vocabulary: ${summary.newWords.join(', ')}`);
```
## Output
- Working conversation session with AI tutor
- Pronunciation assessment with phoneme-level feedback
- Session summary with learning metrics
- Console output showing scores and corrections
## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| Session timeout | Exceeded max duration | Start a new session |
| Audio format invalid | Wrong codec or sample rate | Convert to WAV 16kHz mono |
| Language not supported | Invalid language code | Use supported codes (es, ko, ja, fr, de) |
| Low pronunciation score | Background noise | Record in a quiet environment |
| Rate limit exceeded | Too many requests | Wait and retry with backoff |

## Next Steps
Proceed to `speak-local-dev-loop` for development workflow setup.
## Examples
**Text-only test**: Skip audio and use text responses to test the conversation flow before integrating microphone input.
**Multi-language**: Start sessions in different languages by changing the `language` parameter to `ko` (Korean), `ja` (Japanese), or `fr` (French).

jfrog
IncludedInteract with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.
cupynumeric-migration-readiness
IncludedPre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.
alibabacloud-data-agent-skill
IncludedInvoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".
token-optimizer
IncludedReduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
resend-cli
IncludedUse this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
alibabacloud-odps-maxframe-coding
IncludedUse this skill for MaxFrame SDK development and documentation navigation on Alibaba Cloud MaxCompute (ODPS). Helps answer MaxFrame API, concept, official example, and supported pandas API questions; create data processing programs; read/write MaxCompute tables; debug jobs (remote or local); and build custom DPE runtime images. Trigger when users mention MaxFrame, MaxCompute with MaxFrame, ODPS table processing, DPE runtime, MaxFrame docs/examples, DataFrame/Tensor operations, or GPU runtime setup. Works for both English and Chinese queries about Alibaba Cloud data processing with MaxFrame.
