Code Review — PR #1240: feat(lsp): implement get_hover and get_definitions for LSP runtime
Overall Assessment: ✅ Code Approved — ⚠️ Merge Blocked by Conflict
The implementation is well-structured, spec-aligned, and thoroughly tested. However, the PR cannot be merged due to a merge conflict in
CHANGELOG.md. The branch needs to be rebased onto currentmaster.Specification Alignment ✅
The implementation correctly adds
get_hoverandget_definitionsto bothLspClientandLspRuntime, matching the spec's LSP integration design (LSP Capability Exposure, lines 20695–20741). The tool adapter correctly wires HOVER and DEFINITIONS capabilities to the runtime, bringing the working capability count from 2 to 4 as described in the issue.Code Quality ✅
LspClient methods:
get_hover()correctly sendstextDocument/hoverand handles dict, None, and unexpected return typesget_definitions()correctly sendstextDocument/definitionand handles single Location (dict), Location[], LocationLink[], and null responsesLspRuntime methods:
try/finallyfordid_close()safety — this is an improvement over the existingget_completionsandget_diagnosticspatterns which lack this safety netTool adapter:
Test Quality ✅
21 Behave scenarios covering:
lsp_tool_adapter_coverage.featurecorrectly updated (HOVER → REFERENCES for unimplemented capability test)Minor note: The CHANGELOG entry says "10 Behave BDD scenarios" but the feature file contains 21 scenarios. The PR description correctly states 21.
Consistency Observation (non-blocking)
The new runtime methods use
try/finallyfordid_close()safety, which is an improvement. The existingget_completions()andget_diagnostics()methods don't have this safety pattern. Consider a follow-up issue to retrofittry/finallyto those methods for consistency.Security ✅
No secrets, proper input validation, no injection vectors.
⚠️ Merge Conflict
The branch is based on
2fdac4b4but master has advanced to0db70b95. Both the PR and master added new entries at the top ofCHANGELOG.md's## Unreleasedsection, creating a textual conflict. All source code files (client.py, runtime.py, tool_adapter.py) have no conflicts.Action required: Rebase the branch onto current
masterto resolve the CHANGELOG.md conflict, then this PR is ready to merge.46a5f71b9e05000bddca✅ Code Review — PR #1240: Approved & Merge-Ready
Rebase & Conflict Resolution
The branch was rebased onto current master (
0db70b95) resolving the CHANGELOG.md conflict by keeping both sets of entries:All source code files were conflict-free. The rebased commit is
05000bdd.Code Review Summary (confirming prior review)
Specification Alignment ✅ —
get_hoverandget_definitionscorrectly implement the LSP integration design per spec lines 20695–20741.Code Quality ✅
LspClient: Proper LSP protocol methods with correct response type handling (dict/None for hover, Location/Location[]/LocationLink[]/null for definitions)LspRuntime: Fail-fast input validation, 1→0 coordinate conversion,try/finallyfordid_close()safety (improvement over existing methods)tool_adapter: Clean HOVER and DEFINITIONS dispatch following established COMPLETIONS patternTest Quality ✅ — 21 Behave BDD scenarios covering method existence, all response paths, input validation, and tool adapter wiring.
Security ✅ — No secrets, proper input validation, no injection vectors.

Closes #1243✓Type/Featurelabel ✓needs feedbacklabel ✓mergeable: true✓Non-blocking Observations
Consistency opportunity: The new runtime methods use
try/finallyfordid_close()safety, which is an improvement. The existingget_completions()andget_diagnostics()methods lack this safety pattern. Consider a follow-up issue to retrofittry/finallyto those methods.Minor docstring gap: The new
get_hover()andget_definitions()runtime methods don't includeRaisessections in their docstrings, whileget_completions()does. Non-blocking but worth noting for consistency.CHANGELOG count: The CHANGELOG entry mentions "10 Behave BDD scenarios" but the feature file contains 21 scenarios. The PR description correctly states 21. Minor documentation inaccuracy.
