* agentHost: subagents
* agentHost: remove _meta.parentToolCallId dependency, subscribe to child sessions instead
Inner tool calls from subagent sessions are no longer stored in the parent
turn with _meta.parentToolCallId. Instead:
- Server: _buildTurnsFromMessages skips inner events (parentToolCallId),
_restoreSubagentSession builds child session turns from raw messages
- Client: _enrichHistoryWithSubagentCalls subscribes to child sessions
during history restore, injects serialized inner tool calls with
subAgentInvocationId set
Also fixes hygiene: replace 'in' operator with hasKey in
agentSideEffects.test.ts, exclude .jsonl from copyright filter.
* fix: set terminalCommandUri from terminal content blocks in stateToProgressAdapter
completedToolCallToSerialized and toolCallStateToInvocation were not
detecting terminal tools via ToolResultContentType.Terminal content
blocks or setting terminalCommandUri/terminalToolSessionId, causing
6 test failures in CI.

feat: show breakpoint widget on Alt+click in gutter
Add Alt+click handling in the editor gutter to quickly add or edit
conditional breakpoints. When Alt+clicking on a line without
breakpoints, the breakpoint widget opens in conditional breakpoint
mode. When Alt+clicking on a line with existing breakpoints, the
breakpoint widget opens for editing the first breakpoint.

An Overview button with a home icon sits in the header row alongside

full-width button with label.
* Add marketplace deeplink for Browse buttons in customizations editor
The Browse buttons on MCP Servers and Plugins welcome page cards now
open the section with the marketplace browse mode active instead of
just navigating to the installed list.
- Add public showBrowseMarketplace() to McpListWidget and PluginListWidget
- Extend selectSectionById/selectSection with showMarketplace option
- Add hidden aiCustomization.openMarketplace command for deeplink
- Add selectSectionWithMarketplace callback to welcome page interface
- Wire Browse buttons on MCP/Plugin cards to activate marketplace mode
* Use example placeholder text for workflow input
* Show New/Browse buttons in sessions, use natural language prompts
- Enable showGenerateActions in sessions welcome page
- In sessions, New button prefills chat with 'Create me a {type} that...'
instead of calling generateCustomization via slash commands
- Main Generate Workflow entrypoint uses 'Generate agent customizations.'
instead of /agent-customization in sessions
- Apply same changes to both prompt-launchers and classic welcome pages
* Use /init instead of /agent-customization in core welcome pages
* Remove showGenerateActions flag from IWelcomePageFeatures
Generate actions are now always shown. The conditional was replaced
with a simple promptType check.
* Fix chat prefill to use singular type names with 'custom' prefix
* Increase spacing between subtitle and Generate Workflow block
* Shorten welcome page subtitle
* Fix fixture: add missing selectSectionWithMarketplace callback
terminal: use display command in approval actions (#308895)
Use the display form of the command when computing terminal approval actions so wrapped unsandboxed commands do not leak into confirmation labels.
Also update the runInTerminalTool regression test to assert the display command label.
Mark chat codeblock and diff editor pools as simple widgets so their
text models are not synced to the extension host. This was the original
behavior before #204780 experimentally changed it.
The tool editor pool was already marked as simple.

- Syncs agent-host-protocol to pick up the new
`notify/sessionSummaryChanged` notification type, which lets clients
keep cached session lists in sync without subscribing to every
session URI individually.
- Emits the notification from AgentHostStateManager: after the session
reducer runs, an identity check on the summary object detects
changes, which are debounced (100ms) and flushed as partial diffs.
- Replaces the onDidAction-based subscription-peeking pattern in
AgentHostSessionListController with the cleaner notification-based
approach, removing the need for StateComponents/isSessionAction
imports and the getSubscriptionUnmanaged call.
- Adds unit tests for emission, coalescing, no-op suppression, and
cleanup on session deletion.

(Commit message generated by Copilot)
Restrict bare host detection to a conservative set of coding-related domain suffixes while continuing to treat explicit URLs and SSH remotes as domains.
Add regression coverage for valid and invalid bare suffixes, multi-label hosts, explicit URLs, and dotted non-domain identifiers.
* polish: improve policy-blocked overlay with agents icon, button fixes, and product names
* feat: add AgentsAppEnabled enterprise policy with parent policy identity propagation
- Register chat.agentsApp.enabled configuration with policy support
- Add agents_app_enabled to IPolicyData for account-level policy
- Save parent VS Code policy identity (win32RegValueName/darwinBundleIdentifier)
in bootstrap-meta before product.sub.json merge so the agents sub-app reads
policies from the parent VS Code's registry/plist domain
- Use parentPolicyConfig in main.ts when creating NativePolicyService
- Improve policy-blocked overlay: agents icon, button width fix, keyboard fix,
hardcoded 'Agents' name, Open VS Code scheme fix
* chore: regenerate policyData.jsonc with AgentsAppEnabled policy
* refactor: use existing ChatAgentMode policy instead of separate AgentsAppEnabled
Piggyback on chat.agent.enabled (ChatAgentMode) policy to show the
policy-blocked splash screen in the agents app, rather than introducing
a separate AgentsAppEnabled policy.
* polish: use sessions logo SVG, save parent urlProtocol, update overlay text
- Replace codicon with sessions logo SVG (theme-aware light/dark)
- Save parent urlProtocol in parentPolicyConfig for correct Open VS Code link
- Update overlay title to 'Agents Disabled by Policy'
- Update description to 'Your organization has disabled Agents via policy.'
* fix: update Learn more link to agents docs
* refactor: move sessions logo SVGs to shared location, update title
* fix: cache CCA disabled results with 5-min TTL to reduce /enabled traffic
The checkCCAEnabled() method previously only cached enabled=true results
(introduced in 19541d79ea). For the majority of users whose repos have CCA
disabled, every provideChatSessionProviderOptions() call bypassed the cache
and hit the jobs/:owner/:repo/enabled CAPI endpoint unconditionally. With
growing adoption, this became significant upstream traffic.
Fix: cache all /enabled results. enabled=true keeps the 30-min TTL.
enabled=false/undefined uses a new 5-min TTL (CCA_DISABLED_CACHE_TTL_MS),
short enough that users who just enabled CCA won't wait long, but long enough
to dramatically reduce repeated calls.
To support the shorter TTL for disabled entries without changing the enabled
TTL, TtlCache.set() now accepts an optional per-entry ttlMs override that
takes precedence over the cache-wide TTL.

* fix: surface unexpected /enabled status codes (e.g. 429) in telemetry
Previously, isCCAEnabled's default case returned { enabled: undefined }
with no statusCode, swallowing 429 rate-limit and 5xx responses.
Changes:
- Widen CCAEnabledResult.statusCode from 401|403|422 to number so
unexpected codes can be propagated
- Return statusCode: response.status in isCCAEnabled's default case
- Add sendTelemetryErrorEvent('copilot.codingAgent.CCAIsEnabledUnexpectedStatus')
in checkCCAEnabled for any status code outside {401, 403, 422}, with
isRateLimited flag for quick 429 filtering in dashboards

* Fix 'Generate New Task' no-op on existing sessions
sendAndCreateChat only works for new (untitled) sessions or when
multi-chat is enabled. For existing/completed sessions it threw an
error that was silently swallowed, making the action appear to do
nothing.
Add a _generateNewTask helper that checks the session status:
- Untitled sessions: use sendAndCreateChat (existing first-chat flow)
- Existing sessions: send /generate-run-commands directly to the
active chat widget via acceptInput
Fixes#308805
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address review: use passed-in session, add sendAndCreateChat fallback
- Use session.mainChat.resource instead of re-reading activeSession
from global state, avoiding stale-reference bugs.
- Fall back to sendAndCreateChat when no chat widget is found for
the session, so the action is never a silent no-op.

* Simplify _generateNewTask: consolidate sendAndCreateChat fallback
Both the untitled and widget-not-found paths called sendAndCreateChat,

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.

* 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.

* 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.

* 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.

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.
