Add `timeout_secs` and `agentic_timeout_secs` fields to
`DelegateAgentConfig` so users can tune per-agent timeouts instead
of relying on the hardcoded 120s / 300s defaults.
Validation rejects values of 0 or above 3600s, matching the pattern
used by MCP timeout validation.
Closes#3898
Add support for switching AI models at runtime during a conversation.
The model_switch tool allows users to:
- Get current model state
- List available providers
- List models for a provider
- Switch to a different model
The switch takes effect immediately for the current conversation by
recreating the provider with the new model after tool execution.
Risk: Medium - internal state changes and provider recreation
* fix(tools): wire ActivatedToolSet into tool dispatch and spec advertisement
When deferred MCP tools are activated via tool_search, they are stored
in ActivatedToolSet but never consulted by the tool call loop.
tool_specs is built once before the iteration loop and never refreshed,
so the provider API tools[] parameter never includes activated tools.
find_tool only searches the static registry, so execution dispatch also
fails silently.
Thread Arc<Mutex<ActivatedToolSet>> from creation sites through to
run_tool_call_loop. Rebuild tool_specs each iteration to merge base
registry specs with activated specs. Add fallback in execute_one_tool
to check the activated set when the static registry lookup misses.
Change ActivatedToolSet internal storage from Box<dyn Tool> to
Arc<dyn Tool> so we can clone the Arc out of the mutex guard before
awaiting tool.execute() (std::sync::MutexGuard is not Send).
* fix(tools): add activated_tools field to new ChannelRuntimeContext test site
MCP tools were not visible to delegate subagents because parent_tools
was a static snapshot taken before MCP tool wiring. Switch to interior
mutability (parking_lot::RwLock) so MCP wrappers pushed after
DelegateTool construction are visible at sub-agent execution time.
Closes#3069
Add `agent.tool_call_dedup_exempt` config key (list of tool names) to
allow specific tools to bypass the within-turn identical-signature
deduplication check in run_tool_call_loop. This fixes the browser
snapshot polling use case where repeated calls with identical arguments
are legitimate and should not be suppressed.

Thinking/reasoning models (Kimi K2.5, GLM-4.7, DeepSeek-R1) return a
reasoning_content field in assistant messages containing tool calls.
ZeroClaw was silently dropping this field when constructing conversation
history, causing provider APIs to reject follow-up requests with 400
errors: "thinking is enabled but reasoning_content is missing in
assistant tool call message".
Add reasoning_content: Option<String> as an opaque pass-through at every
layer of the pipeline: ChatResponse, ConversationMessage, NativeMessage
structs, parse/convert/build functions, and dispatcher. The field is
skip_serializing_if = None so it is invisible for non-thinking models.
Closes#1327
Upstream main now derives schemars::JsonSchema on all config structs.
Our HooksConfig and BuiltinHooksConfig were missing it, causing CI
Build (Smoke) failure when the merge commit was compiled.
On non-CLI channels (Telegram, Discord, etc.), tools like shell and
file_write cannot receive interactive approval and are auto-denied,
causing the LLM to see confusing error responses and fabricate answers.
Add a new config option `non_cli_excluded_tools` under `[autonomy]`
that removes specified tools from the tool specs sent to the LLM on
non-CLI channels. This prevents the model from attempting tool calls
that would fail, forcing it to use data already in the system prompt.
The change filters tool_specs in run_tool_call_loop when the
excluded_tools parameter is non-empty. CLI channels are unaffected.

* 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

* style: fix rustfmt formatting issues
Fixed all formatting issues reported by cargo fmt to pass CI lint checks.
- Line length adjustments
- Chain formatting consistency
- Trailing whitespace cleanup
