What it does
Lsp Test Correlation is an agent skill from blackwell-systems/agent-lsp. Find and run the tests that cover a source file. Use after editing a file to discover exactly which test files and test functions need to run — without running the entire test suite.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)
It sits in Testing & QA, covering Test generation. The repository describes itself as: MCP server that orchestrates language servers into agent-native workflows. 65 tools, 30 CI-verified languages. The licence is MIT.
When your agent uses it
- Tasks that involve Test generation
Example prompts
- “/lsp-test-correlation”
Requirements
- Compatibility (from SKILL.md): Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)
- Pre-approved tools (allowed-tools): mcp__lsp__get_tests_for_file, mcp__lsp__find_symbol, mcp__lsp__open_document, mcp__lsp__run_tests
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 38ca488. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
mcp__lsp__get_tests_for_filemcp__lsp__find_symbolmcp__lsp__open_documentmcp__lsp__run_tests
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)
From compatibility in the SKILL.md frontmatter.
Context cost
Lsp Test Correlation loads about 1.4k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 474 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

lsp-test-correlation
Discover which tests cover a source file, then run only those tests. Faster than running the full suite when you've changed one or two files and want targeted feedback.
When to use
- After editing a source file: "Which tests do I need to run for this change?"
- Before committing: run only the tests that cover what you touched
- Debugging a failure: find which test file corresponds to a broken source file
- Code review: understand what test coverage exists for a file before merging
Use /lsp-verify instead when you want to run the full suite and check all
three layers (diagnostics + build + tests). Use this skill when you want fast,
scoped test execution.
Workflow
Step 1 — Find correlated test files
Call get_tests_for_file for each edited source file:
mcp__lsp__get_tests_for_file({ "file_path": "/abs/path/to/source.go" })Returns the test files that correspond to the source file. For multiple edited files, call once per file.
If no test files are returned: the source file may have no dedicated test file, or the mapping is not resolvable (e.g. integration tests in a separate directory). See Step 2 for fallback.
Step 2 — Enumerate test functions (fallback or enrichment)
If get_tests_for_file returns test files, use find_symbol to list
the test functions defined in those files:
mcp__lsp__find_symbol({ "query": "Test" })Filter results to the correlated test files from Step 1. This gives you the specific test function names to run rather than the whole test file.
Fallback (no test files found): query find_symbol for test
functions that contain the changed symbol's name:
mcp__lsp__find_symbol({ "query": "Test<ChangedFunctionName>" })This catches cases where get_tests_for_file misses indirect coverage.
Step 3 — Report the correlation map
Before running, report what was found:
## Test correlation for <file>
Source file: internal/tools/analysis.go
Test files:
→ internal/tools/analysis_test.go
Tests: TestHandleGetCodeActions, TestHandleGetCompletions, TestHandleGetDocumentSymbols
No correlated test files found for: internal/lsp/normalize.go
→ Fallback: TestNormalizeCompletion, TestNormalizeDocumentSymbols (from workspace symbol search)If the user provided run=true or asks to run, proceed to Step 4. Otherwise
stop here and let the user decide.
Show full SKILL.md (184 more words)Show less
Step 4 — Run correlated tests
Run only the correlated test files or functions. Scope as tightly as possible:
Go — run specific package:
mcp__lsp__run_tests({ "workspace_dir": "<root>", "test_filter": "TestHandleGetCodeActions|TestHandleGetCompletions" })If run_tests does not support test_filter, pass the package path instead of
the workspace root to narrow scope. The test output will be smaller and faster
than running ./....
Output handling: If test output is large, do not read it in full. Search for failures:
grep -E "^(FAIL|--- FAIL)" <output_file>Step 5 — Report results
## Test Results
Ran 3 tests in internal/tools/analysis_test.go
PASSED (2):
TestHandleGetCodeActions
TestHandleGetCompletions
FAILED (1):
TestHandleGetDocumentSymbols — expected 3 symbols, got 2 (analysis_test.go:87)
Recommendation: Fix TestHandleGetDocumentSymbols before committing.Multi-file workflow
For changes spanning multiple source files:
- Call
get_tests_for_filefor each changed file in parallel. - Deduplicate the resulting test files (the same test file may cover multiple source files).
- Report the full correlation map before running.
- Run the deduplicated test set once.
## Test correlation for 3 changed files
internal/tools/analysis.go → internal/tools/analysis_test.go
internal/lsp/client.go → internal/lsp/client_test.go, internal/lsp/client_completion_test.go
internal/resources/resources.go → (no dedicated test file)
Deduplicated test files to run: 3Decision guide
| Situation | Action |
|---|---|
get_tests_for_file returns test files | Use those; enumerate functions via find_symbol |
| No test files returned | Fallback to find_symbol with changed symbol names |
| Test files found but no matching test functions | Report gap — this source file may lack unit test coverage |
| More than 10 test files returned | Don't run all; use /lsp-verify for full suite instead |
| Test fails | Run /lsp-verify for full diagnostic picture |
Example
# "I edited internal/tools/symbol_source.go — which tests should I run?"
get_tests_for_file(file_path="/repo/internal/tools/symbol_source.go")
→ internal/tools/symbol_source_test.go
find_symbol(query="TestGetSymbolSource")
→ TestGetSymbolSource_ContainsPosition (line 12)
→ TestGetSymbolSource_FindInnermost (line 34)
→ TestGetSymbolSource_PositionPattern (line 67)
# Report correlation, then run:
run_tests(workspace_dir="/repo", test_filter="TestGetSymbolSource")
