We need proper command detection to make this work flawlessly, but this
does the initial hookup replacing the copilot SDK's terminal tools with
our tools which are backed by real PTY's.

* Agents - re-create state listener when repository is closed/opened

* Add missing line
Also updated some telemetry fields so we can do correlations more easily
* Update hidden Model B agent prompt for evals

* Refine hidden Model B prompt tag structure

* updating prompt to remove codex string
* Redesign chat customizations welcome page

- Extract welcome page into dedicated AICustomizationWelcomePage class
  and aiCustomizationWelcome.css for better code organization
- Replace old banner + card grid with:
  - 'Analyze Your Project and Configure AI' input box that opens
    /agent-customization in chat with user's description
  - 2x3 category card grid (Agents, Skills, Instructions, Hooks,
    MCP Servers, Plugins) with actionable chip buttons
  - Chips prepopulate chat with specific prompts (e.g. 'Create a
    code review agent', 'Enforce coding style')
- Remove redundant 'Chat Customizations' heading (already in tab)
- Remove redundant 'browse by type' pills (cards serve same purpose)
- Improve chip contrast with visible borders and link-colored text
- Tighten card padding and description sizing for cleaner layout

* Polish welcome page: bigger input, separator, more copy

- Make input box taller with rounded corners and inner submit button
  styled like a chat input (pill-shaped submit that fills on hover)
- Add section divider line between input area and card grid
- Add 'Or configure individual customizations:' label above grid
- Expand description copy to mention codebase analysis
- Bump card label font-weight to 600 and restore 12px desc size
- Restore card padding to 14px for better breathing room

* Rework welcome page: stacked list, better input, centered divider

- Replace 2x3 card grid with full-width stacked category list
  where each row shows icon, label, description, and chip buttons
  inline on a single line
- Input box uses cornerRadius-large, proper padding matching chat
  input style, submit button inside with pill shape
- Separator now shows centered text: 'or configure individually'
  with lines extending on both sides
- Reduce max-width to 680px and remove all excess whitespace
- Remove card/grid CSS entirely

* Improve welcome page hierarchy and command styling

- Restore strong page intro with 'Chat Customizations' heading and
  descriptive copy from the original welcome page
- Increase overall scale: wider content, larger workflow heading,
  larger description text, and roomier input box
- Break each section into title row, description row, and command row
  instead of compressing everything into a single line
- Restyle example actions as monospace command-like entries such as
  '/create-skill ...' to better communicate they prepopulate chat
- Make category rows roomier with card-like boundaries and better
  visual hierarchy

* Simplify welcome page into launcher-style sections

- Replace boxed customization cards with lightweight stacked sections
  separated by subtle rules
- Keep the centered 'or configure individually' separator
- Increase overall scale for the intro, workflow heading, copy, and input
- Make command examples look like real slash commands with plain
  command-link styling instead of pill buttons
- Separate each section into title, description, and command rows for
  clearer hierarchy

* Revert welcome page to original design (keep file separation)

Restore the original welcome page layout from main exactly as it was:
- 'Chat Customizations' heading + subtitle
- 'Configure Your AI' getting-started banner
- Responsive card grid with Browse and Generate with AI buttons

The only structural change kept is the file separation:
welcome page logic lives in aiCustomizationWelcomePage.ts and
welcome CSS lives in media/aiCustomizationWelcome.css.

* Replace Configure Your AI banner with chat-style input box

Swap the old getting-started banner for a clean input box styled
like the chat input part: cornerRadius-large, input-background,
submit arrow inside. No highlight borders or extra UI chrome.

* Fix input box focus outlines to match chat input part

Remove the double-outline: the inner monaco-inputbox and the native
input element both had their own focus borders showing through. Force
border/outline to none on both inner elements and let only the outer
container show the single focus border. Use transparent as default
border (matching chat input) and add overflow: hidden to clip inner
outlines at the rounded corners.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Fix inner input box border by passing transparent inputBoxStyles

The InputBox sets an inline style border via applyStyles() which
cannot be overridden by CSS. Pass inputBorder: transparent and
inputBackground: transparent so the inner box is invisible and
only the outer container provides the border.

* Refactor agent customizations welcome page

Split the Agent Customizations welcome page into classic and prompt-launcher variants, add a configuration switch for selecting the implementation, and add component fixtures for the welcome page variants.

* Polish customization welcome page variants

Refine the classic and prompt-launcher welcome pages so the workflow entry point is more prominent and the category actions are simpler and better aligned.

* Swap welcome variants and fix sessions chat prefill

Move the polished workflow-box layout into promptLaunchers (now the default) and restore classic to the origin/main baseline. Add prefillChat callback so the Generate Workflow input works in both the sessions app (via NewChatViewPane.sendQuery) and core VS Code (via workbench.action.chat.open). Enable the getting-started banner in sessions. Fix double-box input styling and card footer alignment.

* Fix input focus outline and polish welcome page layout

Replace InputBox widget with plain <input> element to eliminate the focus border that the global .monaco-workbench input[type=text]:focus rule was applying. Move helper text above the input, match input-row rounding to the outer card, and add strong specificity overrides for all focus states.

* Add performance workflow and heap-snapshot-analysis skills

Add two agent skills for memory/performance investigations:

- vscode-performance-workflow: Drives repeatable VS Code scenarios,
  captures heap snapshots, and includes bundled chat smoke runners
  (chat-memory-smoke, chat-session-switch-smoke).
- heap-snapshot-analysis: Parses V8 heap snapshots, compares before/after,
  and traces retainer paths.

Both skills include scratchpad folders (gitignored) for one-off
investigation scripts organized in dated subfolders with findings.md.

…ation bug (microsoft#308876)

Rename the `inSessions` task property to `inAgents` across all source,
tests, JSON configs, and documentation.

Also fix a bug in `updateTask` where `setProperty` with a numeric
array index was inserting a duplicate entry instead of replacing the
existing one. The fix replaces the entire tasks array with the updated
entry mapped in at the correct index, consistent with how `removeTask`
already works.

* Agents - Changes view pickers should work with multiple chats in a session

* Pull request feedback
* Add auto-approve session config for agent host

Add an autoApprove session config property to the Copilot agent host with
three options: Default Approvals, Bypass Approvals, and Autopilot (Preview).

- Add autoApprove property to resolveSessionConfig() in copilotAgent.ts
  with sessionMutable: true so it can be changed during running sessions
- Auto-approve all tool calls in agentSideEffects when bypass/autopilot
  is active, overriding per-file and per-command approval rules
- Add client-side filtering (autopilot gated by chat.autopilot.enabled,
  enterprise policy disables bypass/autopilot options)
- Show confirmation dialogs matching the extension host permission picker
- Render the picker in MenuId.ChatInputSecondary for running sessions
  (same location as the normal agent permission picker)
- Wire SessionConfigChanged dispatch for mid-session config changes in
  both local and remote agent host session providers
- Add running session config cache with proper lifecycle cleanup
- Handle restored sessions by creating minimal config entries
- Add 4 unit tests for session-level auto-approve behavior

(Written by Copilot)

* Move auto-approve picker to NewSessionControl (left side)

Render the autoApprove picker in the same location as the normal EH
permission picker (Menus.NewSessionControl, left side) instead of
alongside target/branch on the right side.

- Skip autoApprove property in main session config picker
- Add AgentHostNewSessionApprovePicker registered on NewSessionControl
- Existing running session picker on ChatInputSecondary unchanged

(Written by Copilot)

* Use named type for mutableProperties annotation

Address Copilot review: use IResolveSessionConfigResult indexed type
instead of typeof expression for clearer type annotation.

Change OTLP endpoint from gRPC to HTTP in montoring docs
* Fix crash from nulled _session in ChatModel.dispose()

Remove the _session = undefined line that breaks the back-reference
from requests to the ChatModel during dispose. This causes a crash
in chatListRenderer when the _onDidUpdateViewModel event fires and
accesses template.currentElement.sessionResource on a stale item
whose session has been nulled out.

The _requests array is already emptied right after, so the
back-references are broken when the requests are GC'd with the model.

Fixes microsoft#309568

(Written by Copilot)

* Keep safe GC cleanup, only remove _session null-out

Restore the _requests.length, dataSerializer, and _editingSession
cleanup — these null out fields on the ChatModel itself and are safe.
Only the (r as any)._session = undefined line needs to be removed
since it breaks getters accessed by stale event listeners.

fix microsoft#309547 - guard scopedTools derived against disposed widget

The derived observable created in getModeRequestOptions() outlives the
ChatWidget. When MCP tool changes trigger a recompute after the widget
is disposed, this.input is undefined (MutableDisposable cleared),
crashing on .currentModeObs. Add a disposal guard to return the last
snapshot instead. (Written by Copilot)

The reasoningEffort telemetry property on response.success and
response.error events was only reading from requestBody.reasoning?.effort
(Responses API / OpenAI), missing Claude models which set effort via
requestBody.output_config?.effort (Messages API). This adds a fallback
to output_config.effort so both events capture the reasoning effort
level regardless of which API path is used.

…ft#309638)

Cache breakpoints in the summarization prompt cause the prompt-tsx
budget trimmer to throw BudgetExceededError ('No lowest priority node
found') when all remaining children contain cache points. The trimmer
resets its eviction candidate each time it encounters a cache point,
and when every child has one, it never finds a node to evict.

These breakpoints were already stripped from the output messages by
stripCacheBreakpoints() before sending to the model, so they served
no purpose in the summarization render.

Fix: pass enableCacheBreakpoints: false when rendering
ConversationHistorySummarizationPrompt.

Decouple ISession.sessionType from resource URI scheme in RemoteAgentHostSessionsProvider

- Remote copilot agents now use COPILOT_CLI_SESSION_TYPE as their logical
  session type, aligning with local and cloud copilot sessions, while
  keeping the unique per-connection ID as the resource URI scheme and
  language model vendor.

- Extract model picker into remoteAgentHostModelPicker.ts and consolidate
  side-effect imports into remoteAgentHost.contribution.ts.

- Replace DEFAULT_AGENT_PROVIDER with explicit WELL_KNOWN_AGENT_SESSION_TYPES
  mapping from agent host provider names to local session types.

- Update tests and documentation.

(Written by Copilot)
Move agent-host-specific properties out of the common ISessionsProvider
interface into a new IAgentHostSessionsProvider interface in
sessions/common/agentHostSessionsProvider.ts. Add an ID-based
isAgentHostProvider() type guard and replace all unsafe casts with it.
Remove the unnecessary clearSessionConfig coupling from
sessionsManagementService.

(Written by Copilot)
- Clarify isAgentHostProvider doc: ID-based classification, not shape check
- Fix session config member docs: apply to both new and running sessions
