## Setup (3 tasks)

Initial configuration and environment preparation.

* [x] T001 \[S1702] Verify Phase 16 chat, sessions, session detail, and image upload hook contracts plus V23 source anchors before edits (`.spec_system/PRD/phase_17/session_02_chat_tab_write.md`)
* [x] T002 \[S1702] Inventory existing Hermes tab shell, admin panel chat form, and Hermes tests to identify ownership changes (`.spec_system/specs/phase17-session02-chat-tab-write/implementation-notes.md`)
* [x] T003 \[S1702] Create the Chat component directory and export boundary for modular Hermes chat deliverables (`src/components/hermes/chat/index.ts`)

***

## Foundation (5 tasks)

Core structures and base implementations.

* [x] T004 \[S1702] \[P] Define local chat UI message, attachment, action status, and supported image content-type helpers with exhaustive enum handling (`src/components/hermes/chat/chat-types.ts`)
* [x] T005 \[S1702] \[P] Create the Chat thread sidebar with bounded sessions, selected-session state, new-chat action, loading/empty/error/offline states, and accessible button labels (`src/components/hermes/chat/chat-thread-sidebar.tsx`)
* [x] T006 \[S1702] \[P] Create the Chat message list with empty state, selected thread messages, optimistic local messages, streamed output, typing indicator, and private-path-free attachment display (`src/components/hermes/chat/chat-message-list.tsx`)
* [x] T007 \[S1702] \[P] Create the Chat composer with textarea, upload picker, preview/remove controls, cancel/reset/send controls, focus recovery, and disabled states on admin/token/offline/demo gates (`src/components/hermes/chat/chat-composer.tsx`)
* [x] T008 \[S1702] Compose the Hermes Chat tab orchestrator that joins session summaries, selected detail, admin chat, and image upload views with state reset or revalidation on re-entry (`src/components/hermes/chat/hermes-chat-tab.tsx`)

***

## Implementation (8 tasks)

Main feature implementation.

* [x] T009 \[S1702] Add parent-owned selected chat session state to the Hermes page and pass it into `useHermes` for selected session detail fetching with explicit loading, empty, error, and offline states (`src/components/hermes/hermes-read-only-page.tsx`)
* [x] T010 \[S1702] Add the `Chat` tab trigger and content to the cinematic Hermes tab shell with stable responsive tab wrapping and no existing tab regressions (`src/components/hermes/hermes-read-only-page.tsx`)
* [x] T011 \[S1702] Wire thread selection, new-chat reset, and demo session detail fallback into the Chat tab with state reset or revalidation on selected-session changes (`src/components/hermes/chat/hermes-chat-tab.tsx`)
* [x] T012 \[S1702] Implement send flow through `admin.chat.sendPrompt` with duplicate-trigger prevention while in-flight, attachment prompt prefixing, scoped rollback on error, and composer cleanup after successful handoff (`src/components/hermes/chat/hermes-chat-tab.tsx`)
* [x] T013 \[S1702] Implement image attach flow through `admin.images.uploadImage` with supported content-type filtering, duplicate-trigger prevention while in-flight, upload error mapping, attachment removal, and no visible private path rendering (`src/components/hermes/chat/chat-composer.tsx`)
* [x] T014 \[S1702] Render admin-mode-required, token-required, demo-disabled, offline, endpoint-error, and upload-failure hints close to the write controls with platform-appropriate accessibility labels and input support (`src/components/hermes/chat/chat-composer.tsx`)
* [x] T015 \[S1702] Remove or de-emphasize the legacy admin-panel chat form after the Chat tab owns chat writes while preserving persona controls and gate status states (`src/components/hermes/hermes-admin-panel.tsx`)
* [x] T016 \[S1702] Record implementation decisions, private-path handling, and any hook gaps found during the Chat tab integration (`.spec_system/specs/phase17-session02-chat-tab-write/implementation-notes.md`)

***

## Testing (4 tasks)

Verification and quality assurance.

* [x] T017 \[S1702] \[P] Write focused Chat tab tests for demo/live/setup-required/offline/endpoint-error/token/admin-disabled modes, thread selection, new-chat reset, send flow, cancel/reset, and image attachment removal (`src/components/hermes/chat/__tests__/hermes-chat-tab.test.tsx`)
* [x] T018 \[S1702] \[P] Extend Hermes section tests for the new Chat tab trigger/content and update admin-panel assertions after chat ownership moves (`src/components/hermes/__tests__/hermes-sections.test.tsx`)
* [x] T019 \[S1702] \[P] Strengthen admin hook tests for image upload request headers/body and duplicate upload prevention if current coverage is incomplete (`src/hooks/__tests__/use-hermes-admin.test.tsx`)
* [x] T020 \[S1702] Run focused Vitest coverage, `bun run typecheck`, and ASCII/LF validation, recording command results (`.spec_system/specs/phase17-session02-chat-tab-write/implementation-notes.md`)

***

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase17-session02-chat-tab-write/tasks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
