perf(compose): optimize UI recompositions and state caching#21
Conversation
- Mark ChatWorkspaceState, AgentGatewayConfig, ChatMessage, and OnboardingStep as @immutable to enable skippable recompositions. - Cache endpoint URL calculations in ConfigPanel using remember. - Add performance journal in .agents/journal/bolt-journal.md. - Add comments explaining performance optimizations.

🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secret safely. Learn here the best practices.
- Revoke and rotate this secret.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
🦉 GitGuardian detects secrets in your source code to help developers and security teams secure the modern development process. You are seeing this because you or someone else with access to this repository has authorized GitGuardian to scan your pull request.

62-71:⚠️ Potential issue | 🟡 MinorFix Detekt
LongParameterListpipeline failure — consider wrapping parameters in a state holder.The pipeline reports
LongParameterList(7 params, threshold 6). A common Compose idiom is to group related parameters into a state class, which also aligns with the@Immutableapproach used elsewhere in this PR:♻️ Suggested approach
`@Immutable` data class OnboardingScreenState( val step: OnboardingStep, val currentStepIndex: Int, val totalSteps: Int, val isLastStep: Boolean, ) `@Composable` fun OnboardingScreen( state: OnboardingScreenState, onSkip: () -> Unit, onNext: () -> Unit, modifier: Modifier = Modifier, )This drops the parameter count to 4, satisfies Detekt, and gives you another
@Immutableclass for skippable recomposition.🤖 Prompt for AI Agents

AgentGatewayConfigconstruction — it's built identically in two places.
AgentGatewayConfigis instantiated with the same four values both insidesendMessage()(line 103) and in theChatWorkspaceScreencall (line 135). For a PR focused on recomposition optimization, this allocation on every recomposition is unnecessary.Hoist a single remembered instance and reuse it:
♻️ Proposed fix
Add this after the
webhookSecretstate declaration (around line 89):val gatewayConfig = remember(baseUrl, pairingCode, bearerToken, webhookSecret) { AgentGatewayConfig( baseUrl = baseUrl, pairingCode = pairingCode, bearerToken = bearerToken, webhookSecret = webhookSecret, ) }Then remove both inline constructions and use
gatewayConfigdirectly insendMessage()and in theChatWorkspaceScreen(...)call.Also applies to: 135-141

284-299:⚠️ Potential issue | 🟠 MajorAddress Detekt pipeline failures — the build is currently failing.
The Detekt scan reports five errors that block the pipeline:
FunctionNaming(line 78): PascalCase is the standard Compose convention for@Composablefunctions. Suppress at the Detekt config level for composables, or add a file/function-level@Suppress("FunctionNaming").LongParameterList(lines 154, 235, 284): Common in Compose state-hoisting. Either raise the threshold for@Composablefunctions indetekt.yml, or group related parameters into state-holder classes (e.g., aConfigPanelCallbacksinterface).LongMethodonConfigPanel(line 284): At 100 lines vs. a 60-line threshold. Extract the repeateditem { OutlinedTextField(...) }blocks anditem { EndpointCard(...) }blocks into smaller composable helpers to reduce the method length.These are pre-existing patterns exacerbated by the new
bearerToken/webhookSecretparameters. Since the pipeline is red, they should be resolved in this PR.🤖 Prompt for AI Agents

This allows the Compose compiler to skip recompositions when the data hasn't changed, improving UI responsiveness.ConfigPanelwithremember(gatewayConfig.baseUrl). This avoids redundant string manipulations on every recomposition..agents/journal/bolt-journal.mdand inline comments to track and explain these optimizations.All checks passed via
