What it does

Remove Feature Flag is an agent skill from androidx/androidx. Use this skill to remove a feature flag when the flag is no longer needed and its current state must be made permanent. This skill provides a step-by-step workflow for safely removing obsolete feature flags and their associated dead code without introducing regressions or observable behavior changes.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Development environment for Android Jetpack extension libraries under the androidx namespace. Synchronized with Android Jetpack's primary development branch on AOSP. The licence is Apache-2.0.

When your agent uses it

  • Remove a feature flag when the flag is no longer needed and its current state must be made permanent

Example prompts

  • “/remove-feature-flag”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Identify the current value
  2. Replace usages of the feature flag with the current value
  3. Remove dead code
  4. Update tests
  5. Remove the feature flag
  6. Validate the removal

What it can do on your machine

Read from SKILL.md and the folder at commit 40ff481. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remove Feature Flag loads about 1.2k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 589 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use this skill to remove a feature flag when the flag is no longer needed and its current state must be made permanent. This skill provides a step-by-step workflow for safely removing obsolete feature flags and their associated dead code without introducing regressions or observable behavior changes.

Glossary

TermDefinition
Feature FlagA mechanism to toggle functionality without deploying new code. The value can be a boolean, enum, or similar type.
RefactoringThe process of restructuring existing computer code without changing its external, observable behavior. Removing a feature flag is a refactoring change.
Dead CodeCode that is part of the source but is unreachable and can never be executed.

Prerequisites

  • The feature flag to be removed has a determined static value that is permanently enabled or disabled.
  • The project has a standard validation process including tests and linting.

Limitations

  • This skill only covers the removal of the flag and its associated code. It does not cover the process of rolling out or rolling back the feature itself.

Workflow: How to Remove a Feature flag

The primary goal is to remove the feature flag and codepaths related to the feature flag without any observable impact on library behavior.

Step 1: Identify the current value

Determine the final, permanent, static value of the feature flag, which will be used to replace all usages of the feature flag. For a boolean flag, this will either be true or false.

Step 2: Replace usages of the feature flag with the current value

In the codebase, find all instances where the feature flag is used, and replace the usage of the feature flag with the static value from Step 1.

Example:

ComposeUiFlags.isMyFeatureEnabled is a boolean feature flag that being replaced with true.

Before:

kotlin
if (myState && ComposeUiFlags.isMyFeatureEnabled) {
    newBehavior()
} else {
    oldBehavior()
}

After:

kotlin
if (myState) {
    newBehavior()
} else {
    oldBehavior()
}
Step 3: Remove dead code

After replacing the feature flag with a static value, some code paths will become unreachable. This dead code must be removed.

For example:

  • If the static value is true, then a codepath that is only used when the feature flag was false is dead code and must be removed.
  • If the static value is false, then a codepath that is only used when the feature flag was true is dead code and must be removed.
Example:

ComposeUiFlags.isMyFeatureEnabled is a boolean feature flag that is being replaced with true.

Before:

kotlin
if (ComposeUiFlags.isMyFeatureEnabled) {
    newBehavior()
} else {
    oldBehavior()
}

After:

kotlin
newBehavior()

Step 4: Update tests

Find any tests that are related to the feature flag. If a test was validating a codepath that was removed in Step 3, then that test must be removed. If the only place where code is used is in a test, then that code can still be considered unreachable, and must be removed.

Step 5: Remove the feature flag

All places where the feature flag is being read to or written should now be removed. Remove the declaration of the feature flag.

Step 6: Validate the removal
  1. Run All Checks: The project must be validated in the normal manner. Execute all tests and lint checks. All checks must pass.
  2. Handle API Changes: The removal of a feature flag can often cause an API change. If it does, the API files must be updated according to project standards.

Antipatterns

DO
  • DO replace the feature flag check with its static, constant value.
  • DO remove all code paths that have become unreachable (dead code) as a result of the flag's removal.
  • DO remove any tests that were specifically written to cover the deleted, unreachable code.
  • DO run all standard project validations (tests, linting) to confirm that the change has no observable impact.
  • DO update API files if the removal resulted in an API surface change.
DON'T
  • DON'T introduce any change to the application's observable behavior. The removal must be a pure refactoring.
NEVER
  • NEVER leave dead code or obsolete tests in the codebase after removing a feature flag.
