As part of an expression, you can access context information using one of two syntaxes.
github['sha']
github.sha
In order to use property dereference syntax, the property name must start with a letter or _
and contain only alphanumeric characters, -
, or _
.
If you attempt to dereference a nonexistent property, it will evaluate to an empty string.
Determining when to use contextsGitHub Actions includes a collection of variables called contexts and a similar collection of variables called default variables. These variables are intended for use at different points in the workflow:
if
keyword to determine whether a step should run. Once the job is running, you can also retrieve context variables from the runner that is executing the job, such as runner.os
. For details of where you can use various contexts within a workflow, see Context availability.The following example demonstrates how these different types of variables can be used together in a job:
YAMLname: CI on: push jobs: prod-check: if: ${{ github.ref == 'refs/heads/main' }} runs-on: ubuntu-latest steps: - run: echo "Deploying to production server on branch $GITHUB_REF"
name: CI
on: push
jobs:
prod-check:
if: ${{ github.ref == 'refs/heads/main' }}
runs-on: ubuntu-latest
steps:
- run: echo "Deploying to production server on branch $GITHUB_REF"
In this example, the if
statement checks the github.ref
context to determine the current branch name; if the name is refs/heads/main
, then the subsequent steps are executed. The if
check is processed by GitHub Actions, and the job is only sent to the runner if the result is true
. Once the job is sent to the runner, the step is executed and refers to the $GITHUB_REF
variable from the runner.
Different contexts are available throughout a workflow run. For example, the secrets
context may only be used at certain places within a job.
In addition, some functions may only be used in certain places. For example, the hashFiles
function is not available everywhere.
The following table lists the restrictions on where each context and special function can be used within a workflow. The listed contexts are only available for the given workflow key, and may not be used anywhere else. Unless listed below, a function can be used anywhere.

You can print the contents of contexts to the log for debugging. The toJSON
function is required to pretty-print JSON objects to the log.
Warning
When using the whole github
context, be mindful that it includes sensitive information such as github.token
. GitHub masks secrets when they are printed to the console, but you should be cautious when exporting or printing the context.

github
context
The github
context contains information about the workflow run and the event that triggered the run. You can read most of the github
context data in environment variables. For more information about environment variables, see Store information in variables.
Warning
When using the whole github
context, be mindful that it includes sensitive information such as github.token
. GitHub masks secrets when they are printed to the console, but you should be cautious when exporting or printing the context. When creating workflows and actions, you should always consider whether your code might execute untrusted input from possible attackers. Certain contexts should be treated as untrusted input, as an attacker could insert their own malicious content. For more information, see Secure use reference.
github
object
The top-level context available during any job or step in a workflow. This object contains all the properties listed below. github.action
string
The name of the action currently running, or the id
of a step. GitHub removes special characters, and uses the name __run
when the current step runs a script without an id
. If you use the same action more than once in the same job, the name will include a suffix with the sequence number with underscore before it. For example, the first script you run will have the name __run
, and the second script will be named __run_2
. Similarly, the second invocation of actions/checkout
will be actionscheckout2
. github.action_path
string
The path where an action is located. This property is only supported in composite actions. You can use this path to access files located in the same repository as the action, for example by changing directories to the path: cd ${{ github.action_path }}
. github.action_ref
string
For a step executing an action, this is the ref of the action being executed. For example, v2
.
Do not use in the run
keyword. To make this context work with composite actions, reference it within the env
context of the composite action.
github.action_repository
string
For a step executing an action, this is the owner and repository name of the action. For example, actions/checkout
.
Do not use in the run
keyword. To make this context work with composite actions, reference it within the env
context of the composite action.
github.action_status
string
For a composite action, the current result of the composite action. github.actor
string
The username of the user that triggered the initial workflow run. If the workflow run is a re-run, this value may differ from github.triggering_actor

, even if the actor initiating the re-run (github.triggering_actor
) has different privileges. github.actor_id
string
The account ID of the person or app that triggered the initial workflow run. For example, 1234567

The full event webhook payload. You can access individual properties of the event using this context. This object is identical to the webhook payload of the event that triggered the workflow run, and is different for each event. The webhooks for each GitHub Actions event is linked in Events that trigger workflows. For example, for a workflow run triggered by the push
event, this object contains the contents of the push webhook payload. github.event_name
string
The name of the event that triggered the workflow run. github.event_path
string
The path to the file on the runner that contains the full event webhook payload. github.graphql_url
string

of a job. Otherwise, the value of this property will be null
. github.path
string
Path on the runner to the file that sets system PATH
variables from workflow commands. This file is unique to the current step and is a different file for each step in a job. For more information, see Workflow commands for GitHub Actions. github.ref
string
The fully-formed ref of the branch or tag that triggered the workflow run. For workflows triggered by push
, this is the branch or tag ref that was pushed. For workflows triggered by pull_request
, this is the pull request merge branch. For workflows triggered by release
, this is the release tag created. For other triggers, this is the branch or tag ref that triggered the workflow run. This is only set if a branch or tag is available for the event type. The ref given is fully-formed, meaning that for branches the format is refs/heads/<branch_name>
. For pull requests events except pull_request_target
, it is refs/pull/<pr_number>/merge
. pull_request_target
events have the ref
from the base branch. For tags it is refs/tags/<tag_name>
. For example, refs/heads/feature-branch-1
. github.ref_name
string
The short ref name of the branch or tag that triggered the workflow run. This value matches the branch or tag name shown on GitHub. For example, feature-branch-1
.
For pull requests, the format is <pr_number>/merge
.

The default working directory on the runner for steps, and the default location of your repository when using the checkout
action. Example contents of the github
context
The following example context is from a workflow run triggered by the push
event. The event
object in this example has been truncated because it is identical to the contents of the push
webhook payload.
Note
This context is an example only. The contents of a context depends on the workflow that you are running. Contexts, objects, and properties will vary significantly under different workflow run conditions.

env
context
The env
context contains variables that have been set in a workflow, job, or step. It does not contain variables inherited by the runner process. For more information about setting variables in your workflow, see Workflow syntax for GitHub Actions.
You can retrieve the values of variables stored in env
context and use these values in your workflow file. You can use the env
context in any key in a workflow step except for the id
and uses
keys. For more information on the step syntax, see Workflow syntax for GitHub Actions.
If you want to use the value of a variable inside a runner, use the runner operating system's normal method for reading environment variables.
Property name Type Descriptionenv
object
This context changes for each step in a job. You can access this context from any step in a job. This object contains the properties listed below. env.<env_name>
string
The value of a specific environment variable. Example contents of the env
context
The contents of the env
context is a mapping of variable names to their values. The context's contents can change depending on where it is used in the workflow run. In this example, the env
context contains two variables.
{
"first_name": "Mona",
"super_duper_var": "totally_awesome"
}
Example usage of the env
context
This example workflow shows variables being set in the env
context at the workflow, job, and step levels. The ${{ env.VARIABLE-NAME }}
syntax is then used to retrieve variable values within individual steps in the workflow.
When more than one environment variable is defined with the same name, GitHub uses the most specific variable. For example, an environment variable defined in a step will override job and workflow environment variables with the same name, while the step executes. An environment variable defined for a job will override a workflow variable with the same name, while the job executes.

vars
context
The vars
context contains custom configuration variables set at the organization, repository, and environment levels. For more information about defining configuration variables for use in multiple workflows, see Store information in variables.
vars
context
The contents of the vars
context is a mapping of configuration variable names to their values.
{
"mascot": "Mona"
}
Example usage of the vars
context
This example workflow shows how configuration variables set at the repository, environment, or organization levels are automatically available using the vars
context.
Note
Configuration variables at the environment level are automatically available after their environment is declared by the runner.
If a configuration variable has not been set, the return value of a context referencing the variable will be an empty string.
The following example shows using configuration variables with the vars
context across a workflow. Each of the following configuration variables have been defined at the repository, organization, or environment levels.

, failure
, cancelled
, or skipped
. When a continue-on-error
step fails, the outcome
is failure
, but the final conclusion
is success
. steps.<step_id>.outcome
string
The result of a completed step before continue-on-error
is applied. Possible values are success
, failure
, cancelled
, or skipped
. When a continue-on-error
step fails, the outcome
is failure
, but the final conclusion
is success
. steps.<step_id>.outputs.<output_name>
string
The value of a specific output. Example contents of the steps
context
This example steps
context shows two previous steps that had an id
specified. The first step had the id
named checkout
, the second generate_number
. The generate_number
step had an output named random_number
.
{
"checkout": {
"outputs": {},
"outcome": "success",
"conclusion": "success"
},
"generate_number": {
"outputs": {
"random_number": "1"
},
"outcome": "success",
"conclusion": "success"
}
}
Example usage of the steps
context
This example workflow generates a random number as an output in one step, and a later step uses the steps
context to read the value of that output.
name: Generate random failure on: push jobs: randomly-failing-job: runs-on: ubuntu-latest steps: - name: Generate 0 or 1 id: generate_number run: echo "random_number=$(($RANDOM % 2))" >> $GITHUB_OUTPUT - name: Pass or fail run: | if [[ ${{ steps.generate_number.outputs.random_number }} == 0 ]]; then exit 0; else exit 1; fi

uses: actions/upload-artifact@v4
with:
name: Build failure logs
path: ${{ runner.temp }}/build_logs
secrets
context
The secrets
context contains the names and values of secrets that are available to a workflow run. The secrets
context is not available for composite actions due to security reasons. If you want to pass a secret to a composite action, you need to do it explicitly as an input. For more information about secrets, see Using secrets in GitHub Actions.
GITHUB_TOKEN
is a secret that is automatically created for every workflow run, and is always included in the secrets
context. For more information, see Use GITHUB_TOKEN for authentication in workflows.
Warning
If a secret is used in a workflow job, GitHub automatically redacts secrets printed to the log. You should avoid printing secrets to the log intentionally.
Property name Type Descriptionsecrets
object
This context is the same for each job in a workflow run. You can access this context from any step in a job. This object contains all the properties listed below. secrets.GITHUB_TOKEN
string
Automatically created token for each workflow run. For more information, see Use GITHUB_TOKEN for authentication in workflows. secrets.<secret_name>
string
The value of a specific secret. Example contents of the secrets
context
The following example contents of the secrets
context shows the automatic GITHUB_TOKEN
, as well as two other secrets available to the workflow run.
{
"github_token": "***",
"NPM_TOKEN": "***",
"SUPERSECRET": "***"
}
Example usage of the secrets
context
This example workflow uses the GitHub CLI, which requires the GITHUB_TOKEN
as the value for the GH_TOKEN
input parameter:

object
This context changes for each job in a workflow run. You can access this context from any job or step in a workflow. This object contains all the properties listed below. strategy.fail-fast
boolean
When this evaluates to true
, all in-progress jobs are canceled if any job in a matrix fails. For more information, see Workflow syntax for GitHub Actions. strategy.job-index
number
The index of the current job in the matrix. Note: This number is a zero-based number. The first job's index in the matrix is 0
. strategy.job-total

job strategy. For more information, see Workflow syntax for GitHub Actions. Example contents of the strategy
context
The following example contents of the strategy
context is from a matrix with four jobs, and is taken from the final job. Note the difference between the zero-based job-index
number, and job-total
which is not zero-based.
{
"fail-fast": true,
"job-index": 3,
"job-total": 4,
"max-parallel": 4
}
Example usage of the strategy
context
This example workflow uses the strategy.job-index
property to set a unique name for a log file for each job in a matrix.
name: Test strategy on: push jobs: test: runs-on: ubuntu-latest strategy: matrix: test-group: [1, 2] node: [14, 16] steps: - run: echo "Mock test logs" > test-job-${{ strategy.job-index }}.txt - name: Upload logs uses: actions/upload-artifact@v4 with: name: Build log for job ${{ strategy.job-index }} path: test-job-${{ strategy.job-index }}.txt

- name: Upload logs
uses: actions/upload-artifact@v4
with:
name: Build log for job ${{ strategy.job-index }}
path: test-job-${{ strategy.job-index }}.txt
matrix
context
For workflows with a matrix, the matrix
context contains the matrix properties defined in the workflow file that apply to the current job. For example, if you configure a matrix with the os
and node
keys, the matrix
context object includes the os
and node
properties with the values that are being used for the current job.
There are no standard properties in the matrix
context, only those which are defined in the workflow file.
matrix
object
This context is only available for jobs in a matrix, and changes for each job in a workflow run. You can access this context from any job or step in a workflow. This object contains the properties listed below. matrix.<property_name>
string
The value of a matrix property. Example contents of the matrix
context
The following example contents of the matrix
context is from a job in a matrix that has the os
and node
matrix properties defined in the workflow. The job is executing the matrix combination of an ubuntu-latest
OS and Node.js version 16
.
{
"os": "ubuntu-latest",
"node": 16
}
Example usage of the matrix
context
This example workflow creates a matrix with os
and node
keys. It uses the matrix.os
property to set the runner type for each job, and uses the matrix.node
property to set the Node.js version for each job.
name: Test matrix on: push jobs: build: runs-on: ${{ matrix.os }} strategy: matrix: os: [ubuntu-latest, windows-latest] node: [14, 16] steps: - uses: actions/setup-node@v4 with: node-version: ${{ matrix.node }} - name: Output node version run: node --version

}
Example usage of the needs
context
This example workflow has three jobs: a build
job that does a build, a deploy
job that requires the build
job, and a debug
job that requires both the build
and deploy
jobs and runs only if there is a failure in the workflow. The deploy
job also uses the needs
context to access an output from the build
job.
name: Build and deploy on: push jobs: build: runs-on: ubuntu-latest outputs: build_id: ${{ steps.build_step.outputs.build_id }} steps: - name: Build id: build_step run: echo "build_id=$RANDOM" >> $GITHUB_OUTPUT deploy: needs: build runs-on: ubuntu-latest steps: - run: echo "Deploying build ${{ needs.build.outputs.build_id }}" debug: needs: [build, deploy] runs-on: ubuntu-latest if: ${{ failure() }} steps: - run: echo "Failed to build and deploy"
