WalkthroughChangesThe change adds per-ToolSet tool naming modes. LLMAgent validates and applies these modes to static, refreshed, invocation, and activated ToolSets. Original names are supported without changing the Tool name mode support
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR adds configurable ToolSet naming, but it also removes or renames exported APIs that can cause existing downstream users to fail at compile time without a migration path. Merge should wait for backward-compatible aliases or an explicit compatibility decision; targeted validation and documentation follow-up are also needed. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@examples/mcptool/README.md`:
- Line 211: Add the MCP package import alongside the existing tool import in the
example’s import block so the mcp.NewMCPToolSet reference resolves when the
snippet is copied.
In `@tool/name_mode_test.go`:
- Around line 33-38: Extend TestToolNameModeOf_UsesOptionalProvider to use a
provider returning ToolNameMode(99) and assert that ToolNameModeOf maps the
unsupported value to ToolNameModeQualified, while preserving the existing
original-mode coverage.
In `@tool/okf/toolset_test.go`:
- Around line 117-118: Strengthen the model tool-name assertion in the test
around toolByName so the complete exposed set is exactly list and read: verify
both names are present and ensure qualified names such as okf_list are absent.
Preserve the existing failure diagnostics while making the assertion fail for
missing or extra model-facing names.

In `@agent/llmagent/option.go`:
- Around line 942-947: Update the Godoc for WithToolSetToolNameMode to document
that agent construction rejects blank ToolSet names, unsupported
ToolSetToolNameMode values, and ToolSet names that are not registered, so
callers understand these configuration validation errors.
In `@agent/llmagent/tool_activation_test.go`:
- Line 260: Update the first-request assertions in the test using
WithToolSetToolNameMode to verify that both search and the qualified name
github_search are absent before skill_load activation; preserve the existing
post-activation assertions.
In `@internal/tool/toolset.go`:
- Line 38: Update NewNamedToolSetWithMode so it normalizes the requested
nameMode and compares it with an existing NamedToolSet wrapper’s mode. Return
the existing wrapper only when the modes match; otherwise create a new wrapper
around its underlying ToolSet using the requested mode, preserving current
behavior for unwrapped ToolSets.
In `@tool/name_mode.go`:
- Line 15: In the declarations around ToolSetToolNameMode, retain deprecated
public aliases for the renamed ToolNameMode type and the ToolNameModeQualified
and ToolNameModeOriginal constants, mapping them directly to the new symbols so
existing callers continue to compile while migrating.

qualification applies only when ToolSet.Name() is non-empty, while empty names

Fixes #2568
What changed
Add
llmagent.WithToolSetToolNameMode(toolSetName, mode)to configure how a registered ToolSet's tools are exposed to the model.tool.ToolSetToolNameModeQualifiedpreserves the existing{toolSetName}_{toolName}names, whiletool.ToolSetToolNameModeOriginalkeeps each tool declaration's original name. The option applies to static ToolSets, activatable ToolSets, and refreshed ToolSets.The English and Chinese Tool documentation now describe the naming modes, registration-layer usage, identity preservation, uniqueness requirement, and validation behavior.
Why
Tool naming is a model-facing integration concern rather than intrinsic ToolSet state. Keeping the configuration at the LLMAgent registration layer avoids requiring every built-in or user-defined ToolSet to implement an extra interface, and allows the same ToolSet implementation to be exposed differently by different agents.
ToolSet.Name()remains the stable identity used for activation, policy, and tracing.Testing
go test ./agent/llmagent ./internal/tool ./tool ./tool/mcp ./tool/file ./tool/hostexec ./tool/okfgo test ./skilltoolactivation(fromexamples)go vet ./tool ./internal/tool ./tool/file ./tool/hostexec ./tool/mcp ./tool/okf ./agent/llmagentgo test ./...(the pre-existingtool/duckduckgoUnix-socket test is environment-dependent on this host)Notes for reviewers
tool.ToolSetinterface is unchanged; no ToolSet implementation changes are required.tool.ToolSetToolNameModeOriginalonly changes the model-visible declaration name. ToolSet identity and underlying tool calls are unchanged.ToolSet.Name(); invalid modes and unregistered names are rejected during agent construction.
