* feat: add agent-to-agent delegation tool
Add `delegate` tool enabling multi-agent workflows where a primary agent
can hand off subtasks to specialized sub-agents with different
provider/model configurations.
- New `DelegateAgentConfig` in config schema with provider, model,
system_prompt, api_key, temperature, and max_depth fields
- `delegate` tool with recursion depth limits to prevent infinite loops
- Agents configured via `[agents.<name>]` TOML sections
- Sub-agents use `ReliableProvider` with fallback API key support
- Backward-compatible: empty agents map when section is absent
Closes#218

* fix: encrypt agent API keys and tighten delegation input validation
Address CodeRabbit review comments on PR #224:
1. Agent API key encryption (schema.rs):
- Config::load_or_init() now decrypts agents.*.api_key via SecretStore
- Config::save() encrypts plaintext agent API keys before writing
- Updated doc comment to document encryption behavior
- Added tests for encrypt-on-save and plaintext-when-disabled
2. Delegation input validation (delegate.rs):
- Added "additionalProperties": false to schema
- Added "minLength": 1 for agent and prompt fields
- Trim agent/prompt/context inputs, reject empty after trim
- Added tests for blank agent, blank prompt, whitespace trimming

* fix(delegate): replace mutable depth counter with immutable field
- Replace `current_depth: Arc<AtomicU32>` with `depth: u32` set at
construction time, eliminating TOCTOU race and cancel/panic safety
issues from fetch_add/fetch_sub pattern
- When sub-agents get their own tool registry, construct via
`with_depth(agents, key, parent.depth + 1)` for proper propagation
- Add tokio::time::timeout (120s) around provider calls to prevent
indefinite blocking from misbehaving sub-agent providers
- Rename misleading test whitespace_agent_name_not_found →
whitespace_agent_name_trimmed_and_found

Improve tool-call parsing to handle noisy local-model outputs (markdown fenced JSON, conversational wrappers, and raw JSON tool objects) and add regression coverage for these cases.
Also sync rustfmt-required formatting and align crate-level clippy allow-list with Rust 1.92 CI pedantic checks so required lint gates pass consistently.

Fixes#221 - SQLite Memory Override bug.
This PR resolves memory overwrite behavior in autosave paths by replacing fixed memory keys with unique keys, and improves short-horizon recall quality in channel runtime.
**Root Cause**
SQLite memory uses a unique constraint on `memories.key` and writes with `ON CONFLICT(key) DO UPDATE`.
Several autosave paths reused fixed keys (or sender-stable keys), so newer messages overwrote earlier conversation entries.
**Changes**
- Channel runtime: autosave key changed from `channel_sender` to `channel_sender_messageId`
- Added memory-context injection before provider calls (aligned with agent loop behavior)
- Agent loop: autosave keys changed from fixed `user_msg`/`assistant_resp` to UUID-suffixed keys
- Gateway: Webhook/WhatsApp autosave keys changed to UUID-suffixed keys
All CI checks passing.

* fix: add OpenAI-style tool_calls support for MiniMax and other providers
MiniMax and some other providers return tool calls in OpenAI's native
JSON format instead of ZeroClaw's XML-style <invoke> tag format.
This fix adds support for parsing OpenAI-style tool_calls:
- {"tool_calls": [{"type": "function", "function": {"name": "...", "arguments": "{...}"}}]}
The parser now:
1. First tries to parse as OpenAI-style JSON with tool_calls array
2. Falls back to ZeroClaw's original <invoke> tag format
3. Correctly handles the nested JSON string in the arguments field
Added 3 new tests covering:
- Single tool call in OpenAI format
- Multiple tool calls in OpenAI format
- Tool calls without content field
Fixes#226

* fix(providers): correct GLM API base URL to /api/paas/v4
The GLM (Zhipu) provider was using the incorrect base URL
`https://open.bigmodel.cn/api/paas` which resulted in 404 errors
when making API calls. The correct endpoint is
`https://open.bigmodel.cn/api/paas/v4`.
This fixes issue #238 where the agent would appear unresponsive
when using GLM-5 as the default model.
The fix aligns with the existing test `chat_completions_url_glm`
which already expected the correct v4 endpoint.

* feat: add screenshot and image_info vision tools
Add two new tools for visual capabilities:
- `screenshot`: captures screen using platform-native commands
(screencapture on macOS, gnome-screenshot/scrot/import on Linux),
returns file path + base64-encoded PNG data
- `image_info`: reads image metadata (format, dimensions, size) from
header bytes without external deps, optionally returns base64 data
for future multimodal provider support
Both tools are registered in the tool registry and agent system prompt.
Includes 24 inline tests covering format detection, dimension extraction,
schema validation, and execution edge cases.

* fix: resolve unused variable warning after rebase
Prefix unused `resolved_key` with underscore to suppress compiler
warning introduced by upstream changes. Update Cargo.lock.

* fix: address review comments on vision tools
Security fixes:
- Fix JPEG parser infinite loop on malformed zero-length segments
- Add workspace path restriction to ImageInfoTool (prevents arbitrary
file exfiltration via include_base64)
- Quote paths in Linux screenshot shell commands to prevent injection
- Add autonomy-level check in ScreenshotTool::execute
Robustness:
- Add file size guard in read_and_encode before loading into memory
- Wire resolve_api_key through all provider match arms (was dead code)
- Gate screenshot_command_exists test on macOS/Linux only
- Infer MIME type from file extension instead of hardcoding image/png
Tests:
- Add JPEG dimension extraction test
- Add JPEG malformed zero-length segment test

* feat: add multi-turn conversation history and tool execution
Major enhancement to the agent loop:
**Multi-turn conversation:**
- Add `ChatMessage` type with system/user/assistant constructors
- Add `chat_with_history` method to Provider trait (default impl
delegates to `chat_with_system` for backward compatibility)
- Implement native `chat_with_history` on OpenRouter, Compatible,
Reliable, and Router providers to send full message history
- Interactive mode now maintains persistent history across turns
**Tool execution:**
- Agent loop now parses `<tool_call>` XML tags from LLM responses
- Executes tools from the registry and feeds results back as
`<tool_result>` messages
- Agentic loop continues until LLM produces final text (no tool calls)
- MAX_TOOL_ITERATIONS (10) safety limit prevents runaway loops
- System prompt includes structured tool-use protocol with JSON schemas
**Types:**
- `ChatMessage`, `ChatResponse`, `ToolCall`, `ToolResultMessage`,
`ConversationMessage` — full conversation modeling types
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: address review comments on multi-turn + tool execution
- Add history sliding window (MAX_HISTORY_MESSAGES=50) to prevent
unbounded conversation history growth in interactive mode
- Add 404→Responses API fallback in compatible.rs chat_with_history,
matching chat_with_system behavior
- Use super::api_error() for error sanitization in compatible.rs
instead of raw error body (prevents secret leakage)
- Add missing operational logs in reliable.rs chat_with_history:
recovery, non-retryable, fallback switch warnings
- Add trim_history tests
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: address second round of review comments
- Sanitize raw error text in compatible.rs chat_with_system using
sanitize_api_error (prevents leaking secrets in error messages)
- Add chat_with_history to MockProvider in reliable.rs tests so
the retry/fallback path is exercised end-to-end
- Add chat_with_history_retries_then_recovers and
chat_with_history_falls_back tests
- Log warning on malformed <tool_call> JSON instead of silent drop
- Flush stdout after print! in agent_turn so output appears before
tool execution on line-buffered terminals
- Make interactive mode resilient to transient errors (continue
loop instead of terminating session)
