When 429/500 errors occur during tool execution, empty assistant messages
with stopReason='error' and content=[] get persisted to the session file.
These break the tool_use -> tool_result chain that Claude/Gemini require:
- Claude expects every tool_use block to have a matching tool_result
- Empty error messages inserted mid-sequence violate this invariant
- Results in: 'tool_use ids were found without tool_result blocks'
This patch filters out empty error messages when building session context,
allowing sessions to recover gracefully from transient API errors.
Evidence from production:
- 113 of 170 sessions had empty error messages
- Session 30764430 demonstrated recovery: 429 at 14:30:11 IST,
resumed successfully at 14:30:22, completed at 14:30:34
Sorry Peter, one more patch! 🙈
- Add Microsoft 365 Agents SDK packages (@microsoft/agents-hosting,
@microsoft/agents-hosting-express, @microsoft/agents-hosting-extensions-teams)
- Add MSTeamsConfig type and zod schema
- Create src/msteams/ provider with monitor, token, send, probe
- Wire provider into gateway (server-providers.ts, server.ts)
- Add msteams to all provider type unions (hooks, queue, cron, etc.)
- Update implementation guide with new SDK and progress
Add automatic thinking mode support for Z.AI GLM-4.x models:
- GLM-4.7: Preserved thinking (clear_thinking: false)
- GLM-4.5/4.6: Interleaved thinking (clear_thinking: true)
Uses Z.AI Cloud API format: thinking: { type: "enabled", clear_thinking: boolean }
Includes patches for pi-ai, pi-agent-core, and pi-coding-agent to pass
extraParams through the stream pipeline. User can override via config
or disable via --thinking off.

Previously, grammY's default bot.start() processed updates sequentially,
blocking all Telegram messages while one was being handled. This made
maxConcurrent settings ineffective for Telegram.
Now uses @grammyjs/runner which processes updates concurrently, matching
the behavior of Discord (Promise.all) and WhatsApp (fire-and-forget).
Benefits:
- Ack reactions (👀) appear immediately, not after queue clears
- Multiple chats can be processed in parallel
- maxConcurrent setting now works correctly for Telegram
- Long-running tool calls no longer block other conversations
Bun's WebSocket implementation doesn't fully support Playwright's CDP
connection because Playwright bundles its own 'ws' module. This causes
connectOverCDP to timeout.
The patch makes Playwright use the native 'ws' module when running
under Bun, which works with Bun's WebSocket shim.
Fixes browser snapshot/act timeouts after PR #278 (tsx → bun migration).

* cron: skip delivery for HEARTBEAT_OK responses
When an isolated cron job has deliver:true, skip message delivery if the
response is just HEARTBEAT_OK (or contains HEARTBEAT_OK at edges with
short remaining content <= 30 chars). This allows cron jobs to silently
ack when nothing to report but still deliver actual content when there
is something meaningful to say.
Media is still delivered even if text is HEARTBEAT_OK, since the
presence of media indicates there's something to share.
* fix(heartbeat): make ack padding configurable
* chore(deps): update to latest

* fix: ensure type:object in sanitized tool schemas for Antigravity API
The sanitizeSchemaForGoogle function strips unsupported JSON Schema
keywords like anyOf, but this can leave schemas with 'properties' and
'required' fields without a 'type' field. Both Google's Gemini API and
Anthropic via Antigravity require 'type: object' when these fields exist.
This fix adds a post-sanitization check that ensures type is set to
'object' when properties or required fields are present.
Fixes errors like:
- Gemini: 'parameters.properties: only allowed for OBJECT type'
- Anthropic: 'tools.6.custom.input_schema.type: Field required'
* fix: regenerate pi-ai patch with proper pnpm format
The patch now correctly applies via pnpm patch-commit, fixing:
- Thinking blocks: skip for Gemini, send with signature for Claude
- Schema sanitization: ensure type:object after removing anyOf
- Remove strict:null for LM Studio/Antigravity compatibility
Tested with all Antigravity models (Gemini and Claude).
* fix: strip thinking tags from block streaming output to prevent Gemini tag leakage
