Github

The Github toolkit contains tools that enable an LLM agent to interact with a github repository. The tool is a wrapper for the PyGitHub library.

Quickstart​

  1. Install the pygithub library
  2. Create a Github app
  3. Set your environmental variables
  4. Pass the tools to your agent with toolkit.get_tools()

Each of these steps will be explained in great detail below.

  1. Get Issues- fetches issues from the repository.

  2. Get Issue- fetches details about a specific issue.

  3. Comment on Issue- posts a comment on a specific issue.

  4. Create Pull Request- creates a pull request from the bot's working branch to the base branch.

  5. Create File- creates a new file in the repository.

  6. Read File- reads a file from the repository.

  7. Update File- updates a file in the repository.

  8. Delete File- deletes a file from the repository.

Setup​

1. Install the pygithub library​

%pip install --upgrade --quiet  pygithub

2. Create a Github App​

Follow the instructions here to create and register a Github app. Make sure your app has the following repository permissions:

  • Commit statuses (read only)
  • Contents (read and write)
  • Issues (read and write)
  • Metadata (read only)
  • Pull requests (read and write)

Once the app has been registered, you must give your app permission to access each of the repositories you whish it to act upon. Use the App settings on github.com here.

3. Set Environmental Variables​

Before initializing your agent, the following environmental variables need to be set:

  • GITHUB_APP_ID- A six digit number found in your app's general settings
  • GITHUB_APP_PRIVATE_KEY- The location of your app's private key .pem file, or the full text of that file as a string.
  • GITHUB_REPOSITORY- The name of the Github repository you want your bot to act upon. Must follow the format {username}/{repo-name}. Make sure the app has been added to this repository first!
  • Optional: GITHUB_BRANCH- The branch where the bot will make its commits. Defaults to repo.default_branch.
  • Optional: GITHUB_BASE_BRANCH- The base branch of your repo upon which PRs will based from. Defaults to repo.default_branch.

Example: Simple Agent​

os.environ["GITHUB_REPOSITORY"] = "username/repo-name"
os.environ["GITHUB_BRANCH"] = "bot-branch-name"
os.environ["GITHUB_BASE_BRANCH"] = "main"

# This example also requires an OpenAI API key
os.environ["OPENAI_API_KEY"] = ""
llm = ChatOpenAI(temperature=0, model="gpt-4-1106-preview")
github = GitHubAPIWrapper()
toolkit = GitHubToolkit.from_github_api_wrapper(github)
tools = toolkit.get_tools()

# STRUCTURED_CHAT includes args_schema for each tool, helps tool args parsing errors.
agent = initialize_agent(
    tools,
    llm,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,

Example: Read an issue, open a pull request​

Workflow:

  1. Read issues, either a specific one or just ask it to look at recent ones.
  2. Write code, commit it to a new branch.
  3. Open a PR
  4. "Request review" on the PR from the original author of the issue.

Please implement these changes by creating or editing the necessary files. 

1. First use read_file to read any files in the repo that seem relevant. 
2. Then, when you're ready, start implementing changes by creating and updating files. Implement any and all remaining code to make the project work as the commenter intended. 
2. The last step is to create a PR with a clear and concise title and description, list any concerns or final changes necessary in the PR body.
3. After opening the PR, comment on the original issue and mention the new PR your just opened, you must comment "I opened a PR for you to review here #<PR_NUMBER>" (it'll be something like #30). That hashtag syntax will automatically link to the PR, as necessary. Thanks.
4. If you feel the PR is satisfactory for completing your assignment, create a review request for the original user that opened the issue. Use their username to tag them.

Feel free to ask for help or leave a comment on the Issue or PR if you're stuck.

Thought:The files in the `Report_WholeBrain` directory seem to be mostly reports, images, and some R scripts. However, none of these files appear to be raw RNA-Seq data files or scripts directly related to the RNA-Seq workflow requested by the user. To proceed with creating the workflow, I will need to create new bash and R scripts that will handle the RNA-Seq analysis using the software stack mentioned (FastQC, MultiQC, STAR, RSEM, samtools, DESeq2).

Before creating the scripts, I should create a new branch to work on this feature.

Action:
```json
{
  "action": "Create a new branch",
  "action_input": "rna-seq-workflow"
}
```
Observation: Branch 'rna-seq-workflow_v1' created successfully, and set as current active branch.
Thought:Now that the new branch `rna-seq-workflow_v1` is created and active, I can start creating the necessary bash and R scripts for the RNA-Seq workflow. I will begin by creating a bash script for quality control using FastQC and MultiQC.

Action:
```json
{
  "action": "Create File",
  "action_input": "rna-seq-workflow/01_quality_control.sh\n#!/bin/bash\n#PBS -N quality_control\n#PBS -l walltime=04:00:00\n#PBS -l nodes=1:ppn=8\n#PBS -q batch\n\n# Load modules for FastQC and MultiQC\nmodule load FastQC/0.11.8\nmodule load MultiQC/1.9\n\n# Define input and output directories\nINPUT_DIR='/path/to/raw_data'\nOUTPUT_DIR='/path/to/output/quality_control'\n\n# Create output directory if it doesn't exist\nmkdir -p $OUTPUT_DIR\n\n# Run FastQC on all files in the input directory\nfastqc -o $OUTPUT_DIR -t 8 $INPUT_DIR/*.fastq.gz\n\n# Run MultiQC to aggregate results\nmultiqc -o $OUTPUT_DIR $OUTPUT_DIR\n"
}
```
Observation: Created file rna-seq-workflow/01_quality_control.sh
Thought:The quality control bash script has been created successfully. Next, I will create a bash script for the alignment step using STAR.

Action:
```json
{
  "action": "Create File",
  "action_input": "rna-seq-workflow/02_alignment.sh\n#!/bin/bash\n#PBS -N alignment\n#PBS -l walltime=08:00:00\n#PBS -l nodes=1:ppn=16\n#PBS -q batch\n\n# Load module for STAR\nmodule load STAR/2.7.3a\n\n# Define input and output directories\nINPUT_DIR='/path/to/quality_control'\nOUTPUT_DIR='/path/to/output/alignment'\nGENOME_DIR='/path/to/genome_indices'\n\n# Create output directory if it doesn't exist\nmkdir -p $OUTPUT_DIR\n\n# Run STAR for each sample\nfor sample in $INPUT_DIR/*.fastq.gz\ndo\n  # Define output file names\n  prefix=$(basename $sample .fastq.gz)\n  output_prefix=$OUTPUT_DIR/$prefix\n\n  # Run STAR\n  STAR --runThreadN 16 --genomeDir $GENOME_DIR --readFilesIn $sample --readFilesCommand zcat --outFileNamePrefix $output_prefix --outSAMtype BAM SortedByCoordinate\n\ndone\n"
}
```
Observation: Created file rna-seq-workflow/02_alignment.sh
Thought:The alignment bash script has been created successfully. Next, I will create a bash script for transcript quantification using RSEM.

Action:
```json
{
  "action": "Create File",
  "action_input": "rna-seq-workflow/03_transcript_quantification.sh\n#!/bin/bash\n#PBS -N transcript_quantification\n#PBS -l walltime=12:00:00\n#PBS -l nodes=1:ppn=8\n#PBS -q batch\n\n# Load module for RSEM\nmodule load RSEM/1.3.3\n\n# Define input and output directories\nINPUT_DIR='/path/to/alignment'\nOUTPUT_DIR='/path/to/output/transcript_quantification'\nREFERENCE_DIR='/path/to/reference'\n\n# Create output directory if it doesn't exist\nmkdir -p $OUTPUT_DIR\n\n# Run RSEM for each sample\nfor bam in $INPUT_DIR/*.bam\ndo\n  # Define output file names\n  prefix=$(basename $bam .bam)\n  output_prefix=$OUTPUT_DIR/$prefix\n\n  # Run RSEM\n  rsem-calculate-expression --bam --no-bam-output --estimate-rspd --append-names --output-genome-bam -p 8 $bam $REFERENCE_DIR $output_prefix\n\ndone\n"
}

 Observation: Created file rna-seq-workflow/03_transcript_quantification.sh Thought:The transcript quantification bash script has been created successfully. Now, I will create a bash script for sorting and indexing BAM files using samtools, which is a common step before differential expression analysis.

Action:

{
  "action": "Create File",
  "action_input": "rna-seq-workflow/04_sort_index_bam.sh\n#!/bin/bash\n#PBS -N sort_index_bam\n#PBS -l walltime=02:00:00\n#PBS -l nodes=1:ppn=4\n#PBS -q batch\n\n# Load module for samtools\nmodule load samtools/1.10\n\n# Define input and output directories\nINPUT_DIR='/path/to/alignment'\nOUTPUT_DIR='/path/to/output/sorted_bams'\n\n# Create output directory if it doesn't exist\nmkdir -p $OUTPUT_DIR\n\n# Sort and index BAM files\nfor bam in $INPUT_DIR/*.bam\ndo\n  # Define output file names\n  sorted_bam=$OUTPUT_DIR/$(basename $bam .bam).sorted.bam\n\n  # Sort BAM file\n  samtools sort -@ 4 -o $sorted_bam $bam\n\n  # Index sorted BAM file\n  samtools index $sorted_bam\ndone\n"
}
```
Observation: Created file rna-seq-workflow/04_sort_index_bam.sh
Thought:The sorting and indexing of BAM files script has been created successfully. The next step is to create an R script for differential expression analysis using DESeq2. This script will be executed after the previous steps in the workflow have been completed.

Action:
```json
{
  "action": "Create File",
  "action_input": "rna-seq-workflow/05_differential_expression.R\n# Load DESeq2 library\nlibrary(DESeq2)\n\n# Set input directory\ninput_dir <- '/path/to/transcript_quantification'\n\n# Read in the count matrix and the sample information\n# Assuming countData is a matrix with count data and colData is a DataFrame with sample information\ncountData <- as.matrix(read.csv(file.path(input_dir, 'count_matrix.csv'), row.names=1))\ncolData <- read.csv(file.path(input_dir, 'colData.csv'))\n\n# Create a DESeqDataSet object\ndds <- DESeqDataSetFromMatrix(countData = countData,\n                              colData = colData,\n                              design = ~ condition)\n\n# Run the differential expression analysis\ndds <- DESeq(dds)\n\n# Get the results\nres <- results(dds)\n\n# Order the results by the adjusted p-value\nresOrdered <- res[order(res$padj),]\n\n# Write the results to a CSV file\nwrite.csv(as.data.frame(resOrdered), file.path(input_dir, 'differential_expression_results.csv'))\n"
}

 Observation: Created file rna-seq-workflow/05_differential_expression.R Thought:The R script for differential expression analysis using DESeq2 has been created successfully. Now that all the necessary scripts for the RNA-Seq workflow have been created, I should create a master bash script that will call each of these scripts in sequence to run the entire workflow.

Action:

{
  "action": "Create File",
  "action_input": "rna-seq-workflow/run_workflow.sh\n#!/bin/bash\n# Master script to run the RNA-Seq workflow\n\n# Run quality control\nbash 01_quality_control.sh\n\n# Run alignment\nbash 02_alignment.sh\n\n# Run transcript quantification\nbash 03_transcript_quantification.sh\n\n# Sort and index BAM files\nbash 04_sort_index_bam.sh\n\n# Run differential expression analysis\nRscript 05_differential_expression.R\n\n# Workflow completed\necho \"RNA-Seq workflow completed successfully.\"\n"
}
```
Observation: Created file rna-seq-workflow/run_workflow.sh
Thought:The master bash script to run the entire RNA-Seq workflow has been created successfully. The next step is to create a pull request with all the scripts that have been created in the `rna-seq-workflow_v1` branch.

Action:
```json
{
  "action": "Create Pull Request",
  "action_input": "Create a full command line executable workflow for RNA-Seq on PBMC Samples\n\nThis pull request includes a series of bash and R scripts to perform RNA-Seq analysis on PBMC samples.

If your agent does not need to use all 8 tools, you can build tools individually to use. For this example, we'll make an agent that does not use the create_file, delete_file or create_pull_request tools, but can also use duckduckgo-search.

%pip install --upgrade --quiet  duckduckgo-search
from langchain_community.tools import DuckDuckGoSearchRun
from langchain_core.tools import Tool
from langchain_openai import ChatOpenAI

tools = []
unwanted_tools = ["Get Issue", "Delete File", "Create File", "Create Pull Request"]

for tool in toolkit.get_tools():
    if tool.name not in unwanted_tools:
        tools.append(tool)
tools += [
    Tool(
        name="Search",
        func=DuckDuckGoSearchRun().run,
        description="useful for when you need to search the web",
    )
]

agent = initialize_agent(
    tools=tools,
    llm=ChatOpenAI(temperature=0.1),
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)

Finally let's build a prompt and test it out!

# The GitHubAPIWrapper can be used outside of an agent, too
# This gets the info about issue number 9, since we want to
# force the agent to address this specific issue.

issue = github.get_issue(9)
