Bug Report

Feature Area: LSP Registry / LSP Server Configuration Files
Severity: Medium
Discovered by: UAT Testing (uat-pool-1, worker: Provider Registry and LSP Integration)

What Was Tested

Compared the spec's formal JSON schema for LSP server configuration files against the LspServerConfig Pydantic model.

Expected Behavior (from spec §LSP Server Configuration Files, line 36138)

The spec's formal JSON schema defines these fields:

Field	Type	Required
`name`	string	Yes
`description`	string	No
`languages`	array	Yes
`command`	string	Yes
`args`	array	No
`env`	object	No
`root_path`	string	No (default: `{{ project.root }}`)
`init_options`	object	No
`capabilities`	array	No
`health_check`	object	No

The schema also specifies "additionalProperties": false, meaning only these fields are valid.

Actual Behavior

The LspServerConfig model in src/cleveragents/lsp/models.py uses different field names:

Spec JSON Schema Field	Model Field	Status
`init_options`	`initialization`	MISMATCH — different name
`root_path`	(absent)	MISSING — not in model
`health_check`	(absent)	MISSING — not in model
`workspace_settings`	`workspace_settings`	EXTRA — not in spec JSON schema

Specific Issues

init_options vs initialization: The spec JSON schema uses init_options as the field name, but the model uses initialization. A YAML config file using init_options: will be silently ignored (Pydantic will reject it as an unknown field since model_config has validate_assignment=True).

Note: The spec's informal YAML example (line 20696) uses initialization:, creating an inconsistency within the spec itself. The formal JSON schema should be authoritative.
Missing root_path: The spec schema defines root_path as the workspace root path with Jinja2 template support ({{ project.root }}). The model has no root_path field, so this configuration option is not available.
Missing health_check: The spec schema defines a health_check object with enabled, interval_seconds, restart_on_failure, and max_restarts fields. The model has no health_check field, so health check configuration is not supported.
Extra workspace_settings: The model has a workspace_settings field not present in the spec's formal JSON schema.

Steps to Reproduce

from cleveragents.lsp.models import LspServerConfig
import yaml

# Config using spec's formal JSON schema field names
config_yaml = """
name: local/pyright
command: pyright-langserver
languages: [python]
init_options:
  python.analysis.typeCheckingMode: standard
root_path: "{{ project.root }}"
health_check:
  enabled: true
  interval_seconds: 60
"""
raw = yaml.safe_load(config_yaml)
# This will fail or silently ignore init_options, root_path, health_check:
config = LspServerConfig(**raw)
print(config.initialization)  # {} — init_options was ignored

Impact

Users following the spec's formal JSON schema will find their init_options, root_path, and health_check fields silently ignored
The root_path Jinja2 template feature (workspace root mapping) is not implemented
Health check configuration (periodic probes, auto-restart limits) is not supported
The additionalProperties: false constraint in the spec schema means the model should reject unknown fields, but instead it silently ignores them

Suggested Fix

Rename initialization to init_options in LspServerConfig (or add an alias)
Add root_path: str field with default "{{ project.root }}"
Add health_check: HealthCheckConfig | None field with the spec-defined sub-fields
Decide whether workspace_settings should remain (it's not in the formal JSON schema)

Architecture Supervisor Assessment

Verdict: The spec has an internal inconsistency. The formal JSON schema is authoritative. The implementation needs to align with it.

Analysis

The spec has two conflicting descriptions of LspServerConfig:

Formal JSON schema (line ~36138): Uses init_options, includes root_path and health_check
Informal YAML example (line ~20696): Uses initialization

The formal JSON schema is authoritative per the spec's own rules.

Architectural Ruling

The implementation must align with the formal JSON schema:

initialization → init_options: Rename the field. Use a Pydantic alias if backward compatibility is needed: Field(alias="init_options").
Add root_path: str with default "{{ project.root }}". This enables Jinja2 template resolution to the project's root directory when the LSP server starts.
Add health_check: HealthCheckConfig | None with fields: enabled: bool, interval_seconds: int, restart_on_failure: bool, max_restarts: int.
workspace_settings: This field is not in the formal JSON schema. It should be removed from the model, or the spec should be updated to include it. I will include a spec correction to add workspace_settings to the formal JSON schema in the next corrections PR (it's a reasonable field that the implementation added correctly).

This is a v3.6.0 (Advanced Concepts) deliverable — specifically Deliverable #2: "LSP Registry: agents lsp add/list/show/remove functional."

I will include a spec correction to align the informal YAML example with the formal JSON schema in the next corrections PR.
