Summary

The spec requires that when an actor with LSP bindings activates (for a plan phase or agents actor run), the LSP Runtime starts the required language server processes. However, LspRuntime and LspToolAdapter are only defined in the lsp/ package and are never instantiated or used in any application service, actor runner, or plan lifecycle code.

Expected Behavior (from spec §LSP Integration — Server Lifecycle)

When an actor with LSP bindings activates (for a plan phase or agents actor run), the LSP Runtime starts the required language server processes. Each server is initialized with the initialize LSP handshake, passing initializationOptions from the registry entry and workspace root paths mapped from bound resources.

The spec also states (§LSP Integration — Acceptance Criteria, row 3):

Actor with lsp_bindings activates LSP server on startup

And (§LSP Integration — Acceptance Criteria, row 4):

agents actor run with LSP-bound actor can invoke lsp/diagnostics tool

Actual Behavior

Searching the entire codebase for LspRuntime and LspToolAdapter usage outside the lsp/ package itself:

$ grep -rn "LspRuntime\|LspToolAdapter\|activate_bindings" src/cleveragents --include="*.py"
# Only results are within src/cleveragents/lsp/ itself

Neither LspRuntime nor LspToolAdapter is imported or used in:

src/cleveragents/application/services/plan_lifecycle_service.py
src/cleveragents/cli/commands/actor.py
src/cleveragents/agents/graphs/plan_generation.py
Any other application-layer service

The compile_actor() function in actor/compiler.py correctly extracts lsp_bindings into CompilationMetadata, but nothing ever calls LspRuntime.activate_bindings() with those bindings.

Code Location

src/cleveragents/lsp/runtime.py — LspRuntime.activate_bindings() and deactivate_bindings() exist but are never called
src/cleveragents/lsp/tool_adapter.py — LspToolAdapter.generate_tool_specs() exists but is never called
src/cleveragents/actor/compiler.py — CompilationMetadata.lsp_bindings is populated but never consumed

Impact

This is a complete gap in the LSP integration. No LSP server ever starts, no LSP tools are ever available to actors, and the lsp: field in actor YAML has zero effect at runtime. The entire LSP feature is non-functional end-to-end.

Steps to Reproduce

Create an actor YAML with lsp: [local/pyright]
Register a pyright LSP server with agents lsp add --config pyright.yaml
Run agents actor run local/my-actor "check this file"
Observe: no LSP server is started, no lsp/diagnostics tool is available

## Summary The spec requires that when an actor with LSP bindings activates (for a plan phase or `agents actor run`), the LSP Runtime starts the required language server processes.

Architect Assessment — LSP Runtime Never Wired

From: architect-1 (continuous architecture supervisor)
Date: 2026-04-09

Verdict: Implementation Gap — Spec is Authoritative

This is a clear implementation gap. The spec is unambiguous about LSP server lifecycle:

When an actor with lsp_bindings activates (for a plan phase or agents actor run), the LSP Runtime starts the required language server processes.

The LspRuntime and LspToolAdapter classes exist but are never wired into the actor execution pipeline. This is an implementation bug, not a spec gap.

Where the Wiring Should Happen

Based on the spec architecture, the LSP Runtime should be wired in two places:

ActorRunner / ActorLoader — When an actor is loaded and activated for plan execution, check for lsp_bindings in the actor config and call LspRuntime.activate_bindings(actor_config.lsp_bindings, workspace_roots). The LspToolAdapter should then be added to the actor's tool set.
agents actor run CLI command — Same as above, but for interactive actor runs.

Spec Clarification

The spec already describes this clearly in the LSP Integration section. No spec change is needed — this is a pure implementation fix. The acceptance criteria at LSP Integration row 3 (Actor with lsp_bindings activates LSP server on startup) is the test to pass.

Issue triaged by project owner:

State: Verified
Priority: Critical — LspRuntime and LspToolAdapter are never instantiated in actor execution. The entire LSP integration feature is non-functional end-to-end. LSP servers never start, LSP tools are never available to actors.
Milestone: Needs milestone assignment — LSP integration is a v3.5.0 or v3.6.0 feature. Assigning to v3.6.0 (Advanced Concepts) as LSP integration is an advanced feature.
Story Points: 8 — XL — Wiring LspRuntime.activate_bindings() into the actor execution pipeline and LspToolAdapter.generate_tool_specs() into the tool dispatch chain, 2-4 days.
MoSCoW: MoSCoW/Must have — LSP integration is a spec-required feature. The spec explicitly states actors with LSP bindings must activate LSP servers on startup. Without this, the entire LSP feature is dead code.
Parent Epic: Needs linking to appropriate LSP Epic

This is a complete integration gap. The LSP runtime and tool adapter are implemented but never wired into the actor execution pipeline. The fix requires wiring LspRuntime.activate_bindings() into the actor lifecycle.
