Bug Report

Feature Area: LSP Tool Adapter / LSP Capability Exposure
Severity: High
Discovered by: UAT Testing (uat-pool-1, worker: Provider Registry and LSP Integration)


What Was Tested

Code-level analysis of LspToolAdapter.generate_tool_specs() in src/cleveragents/lsp/tool_adapter.py against the spec's LSP Capability Exposure section.

Expected Behavior (from spec §LSP Capability Exposure, line 20856)

The spec defines a fixed set of tool names for LSP capabilities:

Capability Tool Name
diagnostics lsp/diagnostics
hover lsp/hover
completions lsp/completions
definitions lsp/definition
references lsp/references
rename lsp/rename
code_actions lsp/code-actions
formatting lsp/format
signature_help lsp/signature
document_symbols lsp/symbols
workspace_symbols lsp/workspace-symbols

The spec explicitly states (line 20880):

"When multiple LSP servers are bound to an actor (e.g., local/pyright for Python and local/typescript-lsp for TypeScript), the tool adapter routes requests to the appropriate server based on the file's detected language. The tool names remain the same — routing is transparent to the actor."

This means actors always call lsp/diagnostics, never local/pyright/diagnostics or local/typescript-lsp/diagnostics. The routing to the correct server is done transparently by the adapter.

Actual Behavior

LspToolAdapter.generate_tool_specs() in src/cleveragents/lsp/tool_adapter.py (line 218):

tool_name = f"{config.name}/{suffix}"

This generates server-specific tool names like:

  • local/pyright/diagnostics (should be lsp/diagnostics)
  • local/pyright/hover (should be lsp/hover)
  • local/ts-server/completions (should be lsp/completions)

Verification:

from cleveragents.lsp.tool_adapter import LspToolAdapter
from cleveragents.lsp.models import LspServerConfig, LspCapability

adapter = LspToolAdapter()
config = LspServerConfig(
    name="local/pyright",
    command="pyright-langserver",
    languages=["python"],
    capabilities=[LspCapability.DIAGNOSTICS, LspCapability.HOVER]
)
specs = adapter.generate_tool_specs(config)
print([s["name"] for s in specs])
# Output: ['local/pyright/diagnostics', 'local/pyright/hover']
# Expected: ['lsp/diagnostics', 'lsp/hover']

Impact

  1. Actors cannot use the spec-defined tool names — any actor prompt or skill that references lsp/diagnostics will fail because the tool is registered as local/pyright/diagnostics
  2. Multi-server routing is broken — when both local/pyright and local/ts-server are bound, actors would need to call local/pyright/diagnostics for Python files and local/ts-server/diagnostics for TypeScript files, defeating the purpose of transparent routing
  3. Spec compliance — the spec explicitly defines lsp/diagnostics as the tool name; using server-specific names is a direct spec violation

Suggested Fix

Change generate_tool_specs() to use the spec-defined generic tool names:

# Instead of:
tool_name = f"{config.name}/{suffix}"

# Use:
tool_name = f"lsp/{suffix}"

The routing to the correct server should be handled by the adapter based on the file's detected language (using LanguageDiscovery). When multiple servers are bound, the handler should select the appropriate server based on the file extension.

Architecture Supervisor Assessment

Verdict: The specification is correct. The LspToolAdapter must use generic lsp/* tool names, not server-specific names.

The spec is explicit: "The tool names remain the same — routing is transparent to the actor." This is a fundamental design principle of the LSP integration — actors call lsp/diagnostics, not local/pyright/diagnostics.

Architectural Ruling

The fix is straightforward:

# Change from:
tool_name = f"{config.name}/{suffix}"
# To:
tool_name = f"lsp/{suffix}"

Multi-server routing must be handled transparently by the LspToolAdapter based on the file's detected language. When multiple LSP servers are bound to an actor, the adapter selects the appropriate server based on the file extension/language detected in the tool call arguments.

This is a v3.6.0 (Advanced Concepts) deliverable — specifically Deliverable #4: "LSP capabilities exposed as tools via LSPToolAdapter."

The spec is correct. The implementation needs to be fixed.
