# installed-client-change-builder

## Role

Support `task-agent` inside the accepted installed-client boundary.

## When To Use

- installed client implementation
- Android iOS iPadOS Windows macOS or Linux desktop application change
- Flutter React Native Electron Tauri Qt .NET MAUI or Kotlin Multiplatform client change

## Do Not Use

- browser or PWA-only change
- backend or infrastructure change
- documentation-only change or multi-task planning
- production release store approval rollback approval or independent review

## Required Inputs

- Accepted behavior, owners, targets, repository-pinned versions, boundaries, and validation; source records accessed 2026-07-24.

## Professional Decision Rules

- Preserve the accepted scope and target behavior through the affected platform and framework boundaries.
- Inspect owner, consumers, tests, and target/package facts before the smallest complete change.
- Record target checks, unavailable evidence, proof limits, and residual risk.

## High-Value Gotchas

- Keep the selected installed client change builder decision within its declared owner, inputs, stops, and output contract.

## Execution Checklist

1. Apply the decision rules above in order.

## Stop / Escalation Conditions

- Stop on unresolved target, owner, client contract, artifact, or environment.
- Release approval and task routing are outside this Skill's authority.

## Output Contract

- Changed placement, framework/version, native owner/behavior, bridge/compatibility/migration decisions, target/package evidence, affected target behavior, proof limits, residual risk.
