 The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the [hosted virtual environments](https://github.com/actions/virtual-environments), or you can [self-host the runner](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners) in your own environment.

+# ADR 1438: Support Conditionals In Composite Actions
+
+**Date**: 2021-10-13
+
+**Status**: Accepted
+
+## Context
+
+We recently shipped composite actions, which allows you to reuse individual steps inside an action. 
+However, one of the [most requested features](https://github.com/actions/runner/issues/834) has been a way to support the `if` keyword.
+
+### Goals
+- We want to keep consistent with current behavior
+- We want to support conditionals via the `if` keyword
+- Our built in functions like `success` should be implementable without calling them, for example you can do `job.status == success` rather then `success()` currently.
+
+### How does composite currently work?
+
+Currently, we have limited conditional support in composite actions for `pre` and `post` steps. 
+These are based on the `job status`, and support keywords like `always()`, `failed()`, `success()` and `cancelled()`. 
+However, generic or main steps do **not** support conditionals.
+
+By default, in a regular workflow, a step runs on the `success()` condition. Which looks at the **job** **status**, sees if it is successful and runs.
+
+By default, in a composite action, main steps run until a single step fails in that composite action, then the composite action is halted early. It does **not** care about the job status.
+Pre, and post steps in composite actions use the job status to determine if they should run.
+
+### How do we go forward?
+
+Well, if we think about what composite actions are currently doing when invoking main steps, they are checking if the current composite action is successful. 
+Lets formalize that concept into a "real" idea.
+
+- We will add an `action_status` field to the github context to mimic the [job's context status](https://docs.github.com/en/actions/learn-github-actions/contexts#job-context).
+  - We have an existing concept that does this `action_path` which is only set for composite actions on the github context.
+- In a composite action during a main step, the `success()` function will check if `action_status == success`, rather then `job_status == success`. Failure will work the same way. 
+  - Pre and post steps in composite actions will not change, they will continue to check the job status.
+
+
+### Nested Scenario
+For nested composite actions, we will follow the existing behavior, you only care about your current composite action, not any parents. 
+For example, lets imagine a scenario with a simple nested composite action
+
+```
+- Job
+  - Regular Step
+  - Composite Action
+    - runs: exit 1
+    - if: always()
+      uses: A child composite action
+        - if: success()
+          runs: echo "this should print"
+        - runs: echo "this should also print"
+    - if: success()
+      runs: echo "this will not print as the current composite action has failed already"
+      
+```
+The child composite actions steps should run in this example, the child composite action has not yet failed, so it should run all steps until a step fails. This is consistent with how a composite action currently works in production if the main job fails but a composite action is invoked with `if:always()` or `if: failure()`
+
+### Other options explored
+We could add the `current_step_status` to the job context rather then `__status` to the steps context, however this comes with two major downsides:
+- We need to support the field for every type of step, because its non trivial to remove a field from the job context once it has been added (its readonly)
+  - For all actions besides composite it would only every be `success`
+  - Its weird to have a `current_step` value on the job context
+- We also explored a `__status` on the steps context.
+  - The `__` is required to prevent us from colliding with a step with id: status
+  - This felt wrong because the naming was not smooth, and did not fit into current conventions.
+
+### Consequences
+- github context has a new field for the status of the current composite action.
+- We support conditional's in composite actions
+- We keep the existing behavior for all users, but allow them to expand that functionality.

 ## Features
 
-- Collect more telemetry
+- Expose GITHUB_REF_* as environment variable (#1314)
-- Make `runner.name` available as a runner context variable
+- Add arch to runner context (#1372)
-- Add attempt number (`run_attempt`) to GitHub context 
+- Support Conditional Steps in Composite Actions (#1438)
-- When using the `--ephemeral` flag, ensure that the runner cleans up local `.runner` and `.credentials` files after completion (#1337)
+- Log current runner version in terminal (#1441)
+
+## Bugs
+
+- Makes the user keychains available to the service (#847)
+- Use Actions Service health and api.github.com endpoints after connection failure on Actions Server and Hosted (#1385)
+- Fix an issue where nested local composite actions did not correctly register post steps (#1433)
 
 ## Misc
 
-- Improved network troubleshooting docs
+- Cleanup Older versions on MacOS now that we recreate node versions as needed (#1410)
 
 ## Windows x64
 We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
