* feat: spill large tool results to artifacts, show tail
- Add centralized spillLargeResultToArtifact() in wrappedExecute pipeline
- Tool results exceeding 50KB saved as session artifacts via saveArtifact()
- Content truncated to tail (20KB / 500 lines) instead of head
- Truncation notice includes artifact:// reference for full output retrieval
- Skip spill when tool already saved its own artifact (bash/python/ssh)
- Update formatFullOutputReference to use action-oriented wording
* feat: per-turn token usage display on assistant messages
* fix: TS errors in output-meta truncation fields
* fix(browser): route localhost through proxy when PUPPETEER_PROXY is set
Chrome bypasses proxies for localhost/loopback by default (since v72).
Add --proxy-bypass-list=<-loopback> so localhost traffic reaches mitmdump,
enabling proxy_traffic.log to capture auth flows for local targets.

* Add PUPPETEER_PROXY and PUPPETEER_PROXY_IGNORE_CERT_ERRORS env vars
- PUPPETEER_PROXY: routes browser traffic through specified proxy
- PUPPETEER_PROXY_IGNORE_CERT_ERRORS: ignore HTTPS cert errors when set

* fix(browser): gate PUPPETEER_PROXY_IGNORE_CERT_ERRORS on explicit truthy parse
Previously any non-empty value (including 'false', '0') enabled
--ignore-certificate-errors, silently disabling TLS verification when
operators intended to keep it on. Now only 'true', '1', 'yes', 'on'
(case-insensitive) enable the flag.

- Added language module with 39 supported languages and tree-sitter parser bindings for ast-grep integration.
- Exported dedupeParseErrors utility function to remove duplicate parse error messages in tool output.
- Fixed duplicate parse error messages when multiple patterns fail on the same file.
- Replaced language alias lookup with O(1) phf::Map and added 30+ new language aliases (golang, julia, toml, zig, etc.).
- Migrated from ast-grep-language to direct tree-sitter language dependencies for improved language support.
- Added `fetch.useKagiSummarizer` configuration setting to toggle Kagi Universal Summarizer usage in fetch tool.
- Updated fetch tool to conditionally apply Kagi summarization based on configuration setting.
- Added comprehensive test coverage for Kagi summarizer toggle behavior with mocked dependencies.
- Added Kagi Universal Summarizer integration for URL and YouTube video summarization with fallback support.
- Exported `searchWithKagi` and `summarizeUrlWithKagi` functions from new shared `web/kagi` module for reuse across components.
- Changed HTML-to-text rendering priority to attempt Kagi summarization first before Jina, Trafilatura, and Lynx.
- Refactored Kagi search provider to use shared utilities from `web/kagi` module, reducing code duplication.
- Added `KagiApiError` exception class for Kagi API-specific error handling with optional status code tracking.
- Fixed fetch result rendering to properly wrap long lines instead of truncating them.
- Replaced Bun.wrapAnsi with unified wrapTextWithAnsi utility across debug and output modules.
- Corrected content preview calculation to use actual wrapped line count instead of truncated count.
- Add dereferenceJsonSchema() that inlines local $ref pointers and strips
$defs/definitions from MCP tool schemas before they reach LLM providers.
Previously, Anthropic's convertTools() extracted only properties/required,
dropping $defs and leaving dangling $ref — the LLM never saw the actual
type definitions (e.g. SourceAnchorInput enum values from nucleus).
- Silence Ajv logger (logger: false) on all three instances that use
strict: false. MCP servers may declare non-standard format keywords
(e.g. "uint") that caused console.warn() to corrupt TUI output.
- Cache compiled Ajv validators per schema object identity in validation.ts,
eliminating redundant recompilation on every tool call.

- Added mcp:// internal URL protocol for reading MCP server resources via the read tool.
- Removed read_resource tool; MCP resource reading now integrated into read tool with mcp:// URLs.
- Implemented McpProtocolHandler with URI template matching for resolving MCP server resources.
- Updated MCP resource notifications to recommend read(path="mcp://<uri>") syntax.
- Fixed URI template matching to handle empty string expansions in MCP resource queries.
- Fixed LM Studio URL validation to preserve invalid baseUrl instead of applying localhost fallback.
- Fixed MCP notification epoch handling to prevent unsubscribe calls when old subscriptions resolve after re-enabling.
- Extracted hardcoded LM Studio base URL to named constant for improved maintainability.
- Refactored notification epoch check logic for improved code clarity and readability.
- Normalize LM Studio discovery URLs to avoid duplicated /v1 segments
- Harden status-line PR cache with branch+repo context validation and guarded async writes
- Apply Foundry auth precedence correctly and preserve system trust roots when custom CA is provided
- Split Copilot premium multiplier handling by plan tier while preserving agent-initiated zero billing
- Catch MCP notification refresh failures and route read_resource via deterministic full template matching
- Add regression tests for each fix cluster and keep targeted suites green
* feat(mcp): resource notifications, subscriptions, and read_resource builtin tool
- Add MCP resource subscription lifecycle (subscribe/unsubscribe on connect/disconnect)
- Wire mcp.notifications setting with live toggle support
- Add debounced followUp injection for resource change notifications
- Add global read_resource builtin tool with server resolution by URI/template scheme
- Add MCP prompt commands (buildMCPPromptCommands) with array content support
- Add server instructions injection into system prompt with attribution
- Add mcp.notificationDebounceMs configurable setting
Client (client.ts):
listResources, listResourceTemplates, readResource with pagination
subscribeToResources, unsubscribeFromResources
listPrompts, getPrompt, serverSupportsPrompts
serverSupportsResources, serverSupportsResourceSubscriptions
Manager (manager.ts):
Notification dispatch with subscribed-URI guard
Concurrent refresh deduplication via pending promise map
setNotificationsEnabled with subscribe/unsubscribe toggle
Tests:
client-resources.test.ts (31 tests)
client-prompts.test.ts (20 tests)
mcp-read-resource.test.ts (13 tests)
* fix(mcp): address PR review - eager prompt init and stale subscription cleanup
P1: Make setOnPromptsChanged eagerly fire for servers that already
have prompts loaded. The callback is registered after MCP discovery
has already loaded prompts and fired the hook, so without this the
handler is never called on the common startup path. The fix is in
the manager itself (not the caller), eliminating the race condition
regardless of when the callback is wired.
P2: Unsubscribe removed resource URIs on resource refresh.
refreshServerResources was subscribing to the new URI set and
overwriting #subscribedResources without unsubscribing URIs that
were previously subscribed but no longer present, leaving stale
subscriptions active on the server.
* fix(mcp): add resources and prompts to /mcp help text and subcommand completions
* feat(mcp): add /mcp notifications command
Shows per-server notification capabilities with subscription state:
- Lists supported notification types (tools/list_changed, resources/list_changed,
prompts/list_changed) with check marks
- Shows resources/subscribe status with active subscription count
- Lists subscribed URIs with green ticks when notifications are enabled
- Displays overall enabled/disabled state (mcp.notifications setting)
* fix(mcp): address PR review comments on race conditions and stale state
- Await subscribe/unsubscribe in refreshServerResources so the refresh
promise doesn't resolve before subscriptions are settled, preventing
a second refresh from racing and overwriting tracking state (P2 #3)
- Guard setNotificationsEnabled subscribe .then() against a disable
that happens while the subscribe request is in-flight (P2 #5)
- Re-check mcp.notifications setting inside debounce setTimeout
callback so toggling off mid-window actually suppresses the
follow-up message (P2 #4)
- Fire onToolsChanged and onPromptsChanged callbacks in
disconnectServer so stale slash commands and tool registrations
are cleaned up when a server is removed (P2 #2)
