Add comprehensive unit tests for the ToolRegistry covering registration,
lookup, execution, context injection, async callbacks, schema generation,
provider definition conversion, and concurrent access.
Fix a defensive edge case in Truncate where a negative maxLen would cause
a slice bounds panic, and add table-driven tests covering boundary
conditions, zero/negative lengths, and Unicode handling.

Mistral's API strictly validates tool_calls in assistant messages and
rejects non-standard fields. The ToolCall struct had Name and Arguments
as top-level JSON fields, duplicating data already in Function.Name
and Function.Arguments. OpenAI silently ignored these extras but
Mistral returns 422.
Change json tags to "-" so these internal fields are no longer
serialized to API payloads while remaining available in Go code.
Add Mistral as a first-class provider alongside the 17 existing ones.
Mistral uses the OpenAI-compatible API at https://api.mistral.ai/v1
with provider-specific model prefix stripping (mistral/model → model).
Changes:
- Add Mistral to ProvidersConfig, IsEmpty(), HasProvidersConfig()
- Add mistral entry in default model_list (defaults.go)
- Add mistral protocol in factory_provider.go and getDefaultAPIBase()
- Add mistral prefix stripping in openai_compat normalizeModel()
- Add mistral case in legacy factory.go resolveProviderSelection()
- Add mistral migration entry in ConvertProvidersToModelList()
- Add mistral to supported providers in migrate/config.go
- Add mistral section in config.example.json
- Update AllProviders test (17 → 18 providers)
Tested end-to-end with mistral-small-latest model.
When users migrate from the legacy `providers` config to the new
`model_list` format, voice transcription silently breaks on Telegram,
Discord and Slack channels.
The gateway was reading the Groq API key exclusively from
`cfg.Providers.Groq.APIKey`, which is empty once the key is defined
only inside a `model_list` entry. The transcriber was never initialized,
so voice messages fell back to a plain `[voice]` placeholder.
This fix also scans `model_list` for any entry whose `model` field
starts with `groq/` and uses its `api_key` as a fallback, preserving
full backward compatibility with the legacy `providers.groq` field.
Models like Moonshot kimi-k2.5 and DeepSeek-R1 return a
reasoning_content field in assistant messages. When thinking is enabled,
the API requires this field to be echoed back in subsequent requests.
PicoClaw was silently dropping it, causing 400 errors on tool-call
round-trips.
- Add ReasoningContent to Message and LLMResponse types
- Parse reasoning_content in openai_compat parseResponse()
- Carry reasoning_content through assistant tool-call messages
- Add unit test for reasoning_content parsing
Fixes#588
A race could occur when Close() called conn.Session.Close() concurrently
with an in-flight conn.Session.CallTool(), leading to undefined behavior.
Fix by adding a sync.WaitGroup to Manager:
- CallTool increments the WaitGroup while holding the read lock (after
checking m.closed), ensuring no new calls are counted after Close sets
the flag
- Close sets m.closed=true, releases the write lock, then waits for all
in-flight calls to finish via wg.Wait() before closing sessions
ListAgentIDs() was called on every iteration of the inner tool loop,
causing repeated allocations. Capture the slice once and reuse it for
both agentCount and the registration loop.
Previously Close() discarded all underlying errors and returned only
'failed to close N server(s)', making debugging impossible.
Now each error wraps the server name and original cause, and all errors
are joined so callers can inspect the full failure list.
A line like '=value' would result in envVars[""] = "value", producing
an invalid environment entry for the child process. Return an error
instead when the key is empty.
Add back filesystem, github, brave-search, and postgres as example MCP
server configurations. These were removed from DefaultConfig() to reduce
memory footprint, but should remain in the example config as documentation
for users setting up MCP servers.
CallTool can return (nil, nil) if the underlying MCP library misbehaves.
Without a nil check, result.IsError would panic. Return an explicit error
ToolResult instead.
Avoid building zero services when all services are gated behind profiles.
Without an explicit service target, 'docker compose build' silently skips
all profile-gated services, causing subsequent 'docker compose run' to
use stale or missing images.
