Replace the legacy long-goal skill contract with command-scoped goal tools and runtime guidance. Keep goal state durable across continuations while restricting create and replace mutations to explicit user /goal turns.
Skip process.kill() when returncode is already set so generic exception
handlers after a successful communicate() cannot raise ProcessLookupError.
Suppress race kill failures and still run the safety-net reap.
Add unit and integration coverage for owned-PID reaping on normal exit,
timeout, exception, and exec-session kill/poll paths.
maintainer edit: keep MCP HTTP SSRF checks strict, pin validated DNS for direct web_fetch and HTTP/SSE MCP requests, preserve explicit and environment proxy compatibility, and cover the proxy/redirect/rebinding cases with tests.
Add 'serper' as a web search backend, following the existing provider
pattern (keenable/exa): POST to https://google.serper.dev/search with the
X-API-KEY header, map the 'organic' results into the shared result format,
and fall back to DuckDuckGo when no key is configured.
- key resolved from config.api_key or SERPER_API_KEY env var
- 429 handled with a rate-limit message; other HTTP errors surfaced
- tests cover success, env-key, no-key fallback, HTTP error and rate limit
- docs: add Serper config example and list it in tools.web.search providers
Maintainer edit: preserve raw cmd.exe quoting for shell='cmd', propagate native exit codes through the default PowerShell path, and keep quoted Windows executable paths invokable under PowerShell.
Maintainer edit: prefer pwsh when available so single-line commands support modern PowerShell operators, add -NonInteractive, and parse explicit cmd.exe paths with Windows path semantics for cross-platform tests.
fix(exec): default Windows commands to PowerShell and allow shell parameter
Single-line commands on Windows were routed through cmd.exe
(asyncio.create_subprocess_shell) while multi-line commands used
PowerShell. This caused cross-drive cd failures, missing $VAR expansion,
and inconsistent behavior depending on whether a command contained a
newline. The shell parameter was also rejected on Windows.
- Route all Windows commands through PowerShell by default so single-line
and multi-line commands share the same shell semantics.
- Allow the shell parameter on Windows: accepts powershell, pwsh, or cmd.
- cmd.exe remains reachable via shell="cmd" as an explicit escape hatch.
- Update tests to cover the new default and shell-parameter paths.

maintainer edit: update the existing transient retry tests for reconnect-first behavior and keep structured retry-failure coverage in the focused MCP transient suite.
maintainer edit: treat transient MCP stream failures as dead sessions so the existing reconnect handler can refresh the session before retrying. Also cover retry failure as a structured tool error.
MCP server URLs can carry secrets in userinfo
(`https://user:token@host/sse`) or a query string (`?token=...`). A few
connect/validate paths logged the raw `cfg.url` / `request.url`, so those
secrets could land in log files that are often shared or aggregated.
Add a small `_redact_url()` helper that keeps only scheme/host/port/path
and use it at the four sites that log a server or request URL. Logging
only; no other behavior changes.
MCPToolWrapper.execute only handled TextContent; every other block was
rendered with str(block). An MCP ImageContent block therefore became a
large base64 string embedded in the tool result, which (a) was truncated
by max_tool_result_chars, corrupting the data, and (b) could never reach a
channel because it was plain text, not an image artifact.
Decode ImageContent (and EmbeddedResource blobs with an image/* MIME type)
and persist them via store_generated_image_artifact, returning the same
compact {artifacts, next_step} JSON the built-in image_generation tool
produces. The base64 stays out of the model context; the model delivers the
saved file via the message tool's media parameter.
- Removes match_text regex that stripped # comments before pattern matching
(broke on quoted # inside strings)
- allow_patterns now run re.fullmatch against the full lowercased command
- deny_patterns search the original lowercased command
- Replaces comment-stripping test with comment-tail bypass regression
(touch canary # echo allowlisted must be blocked)
- Adds Re-bin regression for quoted hash + blocked command
(echo "#" followed by blocked command must be caught)
- All 10 tests pass

maintainer edit: add a regression test for the public ExecTool.execute path so omitted login stays non-login by default, and update the Unix environment docstring to match the new explicit login behavior.
The enabledTools allowlist was only enforced for MCP tools returned by
session.list_tools(). Resources and prompts from session.list_resources()
and session.list_prompts() were registered unconditionally, allowing a
deny-all or restrictive enabledTools config to leak resource and prompt
capabilities to the model.
Now resources and prompts are only registered when allow_all_tools is
true (default ["*"] wildcard). Any explicit tool restriction — including
enabledTools: [] (deny-all) or a list of specific tool names — also
blocks resource and prompt registration from that server.
Fixes#4435
- Use a local variable for the proxy URL instead of hardcoding it twice
- Pass proxy through the WebSearchTool constructor instead of mutating
after instantiation (matches real usage path)
- Add assertion that timeout is still forwarded correctly
- Use generic mock data instead of test-specific strings
The DuckDuckGo search provider instantiated DDGS(timeout=10) without
passing the configured proxy, making web_search unusable in environments
that require a proxy (e.g. behind GFW). DDGS supports a proxy parameter
and the proxy value is already available as self.proxy — it was simply
not forwarded.
Add a test verifying the proxy kwarg is forwarded to DDGS.
Keenable's public endpoint serves the free tier (1000 req/hour) without
auth. Route to /v1/search/public with the X-Keenable-Title header when no
key is configured, instead of falling back to DuckDuckGo; keep the
authenticated /v1/search path when an apiKey or KEENABLE_API_KEY is set.

Manual testing against the live API showed the Keenable REST endpoint
(/v1/search) returns 401 without a key — the keyless "free tier" applies
only to the CLI, not the HTTP API. Treat Keenable like every other
key-based provider: fall back to DuckDuckGo when no key is configured,
and drop the now-inaccurate free-tier wording from the docs.
