Context7 - GitHub Search

Search GitHub repositories for issues, PRs, discussions, and code examples to research solutions and best practices.

执行环境

| 路径类型 | 说明 | |---------|------| | 使用方式 | 此技能通过 API 调用使用，无需本地脚本执行 | | 调用场景 | 当用户需要搜索 GitHub 仓库时自动激活 | | 输入参数 | 仓库名称 (owner/repo)、搜索关键词、过滤条件 |

路径说明

• 无本地路径依赖：此技能不涉及本地文件系统操作
• 仓库引用：使用 GitHub 标准格式 owner/repo（如 ggerganov/whisper.cpp）
• 所有路径都是 GitHub 仓库内的路径，与本地文件系统无关

When This Skill Activates

• Keywords: "search GitHub", "find issues", "look up PR", "GitHub discussion"
• Research patterns: "Are there any repo] issues about topic]?"
• Dependency research: Mentions of whisper.cpp, NAudio, WPF, Inno Setup
• Bug investigation: "Has anyone else experienced problem]?"
• Implementation examples: "How do others implement feature]?"

Frequently Searched Repositories

VoiceLite dependencies and related projects:

| Repository | Purpose | When to Search | |------------|---------|----------------| | ggerganov/whisper.cpp | Core transcription engine | Performance optimization, model loading, quantization issues | | naudio/NAudio | Audio recording library | WaveInEvent issues, audio format problems, disposal patterns | | dotnet/wpf | WPF framework | UI threading, XAML binding, Dispatcher issues | | jrsoftware/issrc | Inno Setup installer | Installer configuration, file inclusion, signing | | dotnet/runtime | .NET runtime | Performance issues, GC problems, async/await patterns |

Search Syntax Examples

Search whisper.cpp Performance Issues

Repository: ggerganov/whisper.cpp
Query: "performance optimization" label:performance
Sort: Most commented
Filter: Created after 2024-01-01

# Look for:
- Quantization discussions (Q8_0, Q4_0)
- Flash attention implementations
- Beam size optimization
- Model loading speed improvements

Search NAudio Recording Problems

Repository: naudio/NAudio
Query: "WaveInEvent" label:bug is:closed
Sort: Recently updated

# Look for:
- Disposal patterns (memory leaks)
- Buffer size configurations
- Sample rate issues (16kHz mono)
- Event subscription patterns

Find WPF Dispatcher Examples

Repository: dotnet/wpf
Query: "Dispatcher.Invoke" in:code language:csharp
Filter: Stars >100

# Look for:
- Thread-safe UI updates
- Background worker patterns
- Async dispatcher usage

Search Strategies

1. Start Broad, Then Narrow

Step 1: Search issue titles
  → "transcription slow"

Step 2: Add labels
  → "transcription slow" label:performance

Step 3: Check discussions
  → Switch to Discussions tab for detailed solutions

Step 4: Look at closed issues
  → is:closed (solutions often in closed issues)

2. Finding Solutions

For bugs:

1. Search closed issues first (likely fixed)
2. Check PR descriptions for implementation details
3. Look for "fixed in version X" comments
4. Check release notes for related fixes

For features:

1. Search discussions for design rationale
2. Check PRs for code examples
3. Look for "how to" issues with detailed responses

3. Code Examples

# Search for actual code implementation
in:code language:csharp "WaveInEvent"

# Search for configuration examples
in:file filename:.csproj "NAudio"

# Search for specific patterns
in:code "async Task TranscribeAsync"

Common VoiceLite Research Queries

Whisper.cpp Performance

Query: "Q8_0 quantization" OR "performance improvement"
Repo: ggerganov/whisper.cpp
Labels: performance, optimization
Date: After 2024-01-01

Expected: Quantization benchmarks, speed comparisons, optimization tips

NAudio Memory Leaks

Query: "memory leak" OR "dispose" "WaveInEvent"
Repo: naudio/NAudio
State: Closed (to find fixes)
Sort: Most commented

Expected: Disposal patterns, IDisposable best practices

Inno Setup File Inclusion

Query: "files not included" OR "missing from installer"
Repo: jrsoftware/issrc
Labels: bug, question

Expected: Common .iss mistakes, file path issues, git ignore problems

.NET Process Management

Query: "Process.Kill" OR "zombie process"
Repo: dotnet/runtime
Language: C#

Expected: Proper disposal patterns, timeout handling

Advanced Search Operators

# Combine multiple terms
"whisper performance" AND "quantization"

# Exclude terms
"audio recording" NOT "streaming"

# Search specific user
author:ggerganov "optimization"

# Search by date range
created:>=2024-01-01

# Search by reactions
reactions:>10

# Search by comments
comments:>5

# Search in specific locations
in:title "memory leak"
in:body "WaveInEvent"
in:comments "fixed in"

Workflow Example

Scenario: VoiceLite transcription is slow with tiny model

Step 1: Search whisper.cpp issues
  → Query: "tiny model slow" label:performance
  → Find: Issue #1234 - "Tiny model slower than expected"

Step 2: Read discussion
  → Solution: Enable flash attention, adjust beam size
  → PR #5678 has implementation

Step 3: Check PR for code changes
  → Command line flag: --flash-attn
  → Configuration: beam_size=1

Step 4: Check if applied to VoiceLite
  → Review PersistentWhisperService.cs whisper command
  → Verify flags are present

Step 5: Test & validate
  → Apply if missing, test performance improvement

Troubleshooting Search Results

"Too many results"

• Add more specific labels
• Filter by date (recent issues more relevant)
• Use is:closed for solved problems
• Sort by "Most commented" for well-discussed issues

"No results found"

• Remove labels, search broadly first
• Try synonyms ("slow" vs "performance", "crash" vs "exception")
• Search discussions instead of issues
• Check if repository is active (last commit date)

"Results not relevant"

• Add language filter (language:csharp)
• Search in code instead of issues (in:code)
• Use exact phrases with quotes: "exact error message"
• Exclude common false positives: NOT "unrelated term"

Integration with VoiceLite Development

When researching VoiceLite issues, search these patterns:

Audio Issues: NAudio + "16kHz" OR "mono" OR "WAV format" Transcription Issues: whisper.cpp + "model loading" OR "timeout" OR "process" Performance Issues: whisper.cpp + "Q8_0" OR "optimization" OR "speed" Installer Issues: Inno Setup + "missing files" OR "not included" Memory Issues: .NET + "memory leak" OR "dispose" OR "GC"
