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:

• Search closed issues first (likely fixed)

• Check PR descriptions for implementation details

• Look for "fixed in version X" comments

• Check release notes for related fixes

For features:

• Search discussions for design rationale

• Check PRs for code examples

• 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"
