Summary

Implements comprehensive Zustand-based state management as specified in Issue #10.

Stores Added:

  • useAgentStore: Multi-agent orchestration (Architect, Implementer, Reviewer, Tester)
  • useProjectStore: Repository and workspace state with Git integration hooks
  • useChatStore: Human-agent collaboration with threads, messages, and approval workflows
  • useCredentialStore: API credential metadata management (actual secrets stored in expo-secure-store)
  • useUserStore: User preferences, settings, and GitHub profile

Features:

  • AsyncStorage persistence layer for app restart survival
  • Immer middleware for immutable state updates
  • DevTools integration for debugging
  • Typed selectors for optimal re-renders
  • Comprehensive test suite (46 tests passing)

Architecture Highlights:

  • All stores use immer + persist + devtools middleware stack
  • Credential store only tracks metadata; actual secrets use expo-secure-store
  • Selectors exported alongside stores for component optimization
  • Full TypeScript types for all state and actions

Test plan

  • TypeScript compilation passes
  • Biome linting passes
  • All 46 unit tests pass
  • CI pipeline passes

📝 Walkthrough

Walkthrough

Adds five new Zustand stores (Agent, Chat, Credential, Project, User) with types, selectors, actions, immer immutability, AsyncStorage persistence, devtools integration, and tests; updates Jest setup/config and adds an immer dependency.

Changes

Cohort / File(s) Summary
Configuration & Dependencies
jest.config.js, jest.setup.js, package.json, biome.json, tsconfig.json
Whitelist immer and zustand in Jest transforms, add AsyncStorage mock in test setup, add immer dependency, and adjust tooling/config formatting/ignore patterns.
Agent Store & Tests
src/stores/agentStore.ts, src/stores/__tests__/agentStore.test.ts
New Agent store: types (Agent, AgentTask, AgentRole/Status), actions for agents/tasks/status, persistence key thumbcode-agent-storage, selectors, and comprehensive tests.
Chat Store
src/stores/chatStore.ts
New Chat store: multi-thread messages, code/approval message types, typing/approval flows, capped persistence (last 100 messages/thread), selectors, and devtools/immer integration.
Credential Store & Tests
src/stores/credentialStore.ts, src/stores/__tests__/credentialStore.test.ts
New Credential store: metadata/validation lifecycle, status tracking, selectors (valid/invalid), persistence, and detailed tests.
Project Store
src/stores/projectStore.ts
New Project store: FileNode/Commit/Branch/Project/Workspace types, file & workspace actions, git-like state handling, selective persistence (thumbcode-project-storage), and selectors.
User Store & Tests
src/stores/userStore.ts, src/stores/__tests__/userStore.test.ts
New User store: auth/onboarding, settings (theme/editor/notifications/agents), selectors, defaults, persistence via AsyncStorage, and tests.
Public API Barrel
src/stores/index.ts
Expanded re-exports: types, selectors, and hooks from new store modules; updated header docs reflecting persistence/devtools/architecture.

Poem

🐰 I hopped through files with joyful cheer,

Zustand bunnies building state so clear,
AsyncStorage nibbles bits to keep,
Immer fluffs the branches, tidy and neat,
DevTools winks — let's test and cheer!

Check name Status Explanation
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title check ✅ Passed The pull request title clearly and specifically describes the main change: implementing Zustand state management. It is concise, directly related to the primary objectives, and would be immediately understood by teammates reviewing git history.
Linked Issues check ✅ Passed The PR successfully fulfills all coding requirements from Issue #10: five Zustand stores implemented (useAgentStore, useProjectStore, useChatStore, useCredentialStore, useUserStore), persistence via AsyncStorage, immer integration, DevTools support, typed selectors, comprehensive test suite (46 tests passing), and proper TypeScript configuration updates.
Out of Scope Changes check ✅ Passed All changes are directly scoped to Issue #10 requirements. Updates to jest config and jest setup are necessary infrastructure changes for test support. Package.json additions (immer dependency) directly support the store implementations. No unrelated or extraneous changes detected.
Docstring Coverage ✅ Passed No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

In `@src/stores/__tests__/agentStore.test.ts`:
- Around line 193-204: The test uses a non-null assertion on taskId; initialize
taskId when declaring it to avoid the assertion and satisfy the linter. Change
the declaration of taskId (used with result.current.addTask and
result.current.completeTask) to a defined default (e.g., let taskId = ''; or
assign immediately from addTask) and then call completeTask(taskId, '...')
without the trailing ! so the calls to addTask and completeTask
(result.current.addTask / result.current.completeTask) no longer require a
non-null assertion.
- Around line 164-176: The test uses a non-null assertion on taskId; to satisfy
the noNonNullAssertion lint rule, initialize taskId instead of using "taskId!"
or change its type—e.g., replace "let taskId: string;" with "let taskId = '';"
(or "let taskId: string | undefined = undefined;" and adjust the expect to check
definedness) so you can remove the non-null assertion when comparing
result.current.agents[0].currentTaskId to taskId; update references to taskId
and keep the act(() => { taskId = result.current.addTask(...) }) and subsequent
expects unchanged except removing the "!".

In `@src/stores/chatStore.ts`:
- Around line 243-246: clearThread currently empties state.messages[threadId]
but doesn't touch the unread count, leaving badges for an empty thread; update
the clearThread handler (the clearThread function that calls set and mutates
state.messages[threadId]) to also reset the unread count for that thread by
setting state.unreadCount[threadId] = 0 (or state.unreadCounts[threadId] = 0 if
your store uses plural naming), and guard with a null/undefined check (e.g.,
ensure state.unreadCount exists) so clearing a thread always clears its unread
counter.

In `@src/stores/credentialStore.ts`:
- Around line 177-182: The invalidateAll setter currently only flips
credential.status to 'unknown' but leaves validation metadata, so update the
invalidateAll implementation (the set(...) callback that iterates
state.credentials) to also clear the validation fields by setting each
credential.lastValidatedAt and credential.expiresAt to null (or undefined per
your codebase convention) when you set status = 'unknown'; reference the
invalidateAll method, state.credentials array, and the lastValidatedAt/expiresAt
properties to locate and update the logic.

In `@src/stores/projectStore.ts`:
- Around line 127-135: When removing the active project in removeProject,
branches and recentCommits are left populated causing stale Git info; update the
removeProject handler to also clear state.branches and state.recentCommits when
state.activeProjectId === projectId (similar to how state.workspace and
state.fileTree are set to null) so that state.branches = [] and
state.recentCommits = [] (or null if your store uses null) and thereby fully
reset branch/commit state for the removed active project.
