lsp-rename — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited lsp-rename (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Requires the agent-lsp MCP server.
Renames a symbol across the workspace in two phases: preview first, then execute only after explicit confirmation. Never renames without showing impact.
Invocation: User provides old_name (the symbol to rename) and new_name (the replacement). Optionally provide workspace_root to scope the search.
If LSP is not yet initialized, call mcp__lsp__start_lsp with the workspace root first. Auto-inference applies when file paths are provided, but an explicit start is required when switching workspaces.
Find the symbol, enumerate all references, and produce a dry-run preview. Do not apply any edits in this phase.
Call mcp__lsp__go_to_symbol with symbol_path set to old_name:
mcp__lsp__go_to_symbol
symbol_path: "old_name" # or "Package.OldName" for qualified paths
workspace_root: "<root>" # optional; omit to search entire workspaceThis returns the definition location (file, line, column). If not found, report the error and stop.
Call mcp__lsp__prepare_rename at the definition location from Step 1:
mcp__lsp__prepare_rename
file_path: "<file from Step 1>"
line: <line from Step 1>
column: <column from Step 1>prepare_rename asks the language server whether a rename is valid at this position. If it returns an error (e.g. the symbol is a keyword, a built-in, or in a location the server cannot rename), stop immediately and report:
Cannot rename OldName: <server error message> Common causes: built-in or keyword, imported external package, or position is not on the symbol name. Try locating the declaration site directly.Only proceed to Step 3 if prepare_rename succeeds.
Call mcp__lsp__find_references at the definition location from Step 1:
mcp__lsp__find_references
file_path: "<file from Step 1>"
position_pattern: "<symbol>@@" # @@ immediately after the symbol name
# fallback: use line/column from Step 1 if position_pattern is unavailableCollect all returned locations. Note the total count and the distinct files.
Call mcp__lsp__rename_symbol with dry_run=true. Do not call `apply_edit`.
mcp__lsp__rename_symbol
file_path: "<file from Step 1>"
line: <line from Step 1>
column: <column from Step 1>
new_name: "<new_name>"
dry_run: trueThe response includes a workspace_edit with all proposed changes and a preview.note describing the scope.
Display the preview summary to the user:
Rename preview: OldName -> NewName
Locations to update: N (from find_references count)
Files affected: M (distinct files in workspace_edit)
Language server: <gopls | typescript-language-server | rust-analyzer | ...>
Changes:
path/to/file1.go lines 12, 45, 78
path/to/file2.go line 3
...REQUIRED hard stop — do not proceed without explicit user confirmation:
Proceed with rename? [y/n]
Wait for user input. Do not apply any edit until the user answers "y" or "yes".
If find_references returns an empty list (the symbol exists but has no external usages), warn the user before stopping:
Warning: no references found for OldName. The symbol may be unexported, dead code, or the LSP index may be stale. Renaming will update only the declaration site. Proceed anyway? [y/n]If user answers "n", stop. If "y", continue to Phase 2.
Only enter this phase after the user answers "y" or "yes" to the confirmation prompt in Phase 1.
Before applying changes, capture the current diagnostic state:
mcp__lsp__get_diagnostics
file_path: "<one or more files in the workspace_edit>"Store the result as before_diagnostics.
Call mcp__lsp__rename_symbol without dry_run (or with dry_run=false):
mcp__lsp__rename_symbol
file_path: "<file from Phase 1 Step 1>"
line: <line from Phase 1 Step 1>
column: <column from Phase 1 Step 1>
new_name: "<new_name>"This returns a workspace_edit with the full set of changes.
Call mcp__lsp__apply_edit with the workspace_edit from Step 2:
mcp__lsp__apply_edit
workspace_edit: <workspace_edit from rename_symbol>Call mcp__lsp__get_diagnostics on the affected files and compare against before_diagnostics:
mcp__lsp__get_diagnostics
file_path: "<affected files>"Compute introduced vs. resolved errors and display the Diagnostic Summary (see references/patterns.md).
After Phase 2 completes, display:
## Rename Summary
- Old name: OldName
- New name: NewName
- Files changed: M
- Locations updated: N
- Post-rename errors: 0Follow with the Diagnostic Summary if any errors changed (format in references/patterns.md).
Only show Diagnostic Summary sections where N > 0. A net change of 0 means the rename is safe.
Tested with gopls, typescript-language-server, and rust-analyzer. Most LSP-compliant servers support textDocument/rename — agent-lsp works with any of the 30+ supported language servers that advertise rename capability. Check your server's capability list via mcp__lsp__get_server_capabilities if you are unsure.
