lsp-local-symbols

lsp-local-symbols is a skill for Claude Code from blackwell-systems/agent-lsp. It costs 54 tokens per session (1,354 once invoked), scanned A, original, MIT.

A read-only tool for examining symbols within one source file, such as functions, types, their uses, and their type information.

In plain words
What is it for?
Use it to list what a file defines, find where a symbol is used in that file, check a symbol’s type, or scope a small refactor.
Why use it?
It gives quick answers about a file without searching the whole codebase, while making clear that uses in other files will not be found.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lsp-local-symbols scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Requires the agent-lsp MCP server.

lsp-local-symbols

File-scoped symbol analysis using the language server index. Faster than workspace-wide search for questions about a single file: what symbols are defined here, where is this symbol used within the file, and what type does it have.

Read-only — does not modify any files.

When to use

  • "Where is x used in this file?" — use get_document_highlights
  • "What functions and types are defined in this file?" — use list_symbols
  • "What type does this symbol have?" — use inspect_symbol
  • Reviewing a file before editing — get the full symbol map first
  • Local refactor scoping — confirm a symbol is only used in one place before inlining it

Use /lsp-impact instead when you need workspace-wide callers and cross-file references. Use /lsp-dead-code when auditing exported symbols for zero callers.

When NOT to use

get_document_highlights is file-scoped by design — it only finds usages within the open file. If a symbol is used across multiple files, this skill will not find those. Use find_references (via /lsp-impact) for cross-file analysis.


Workflow

Step 1 — Open the file

Open the file so the language server tracks it:

mcp__lsp__open_document
  file_path: "/abs/path/to/file.go"
  language_id: "go"              # go, typescript, python, rust, etc.

Step 2 — List all symbols in the file

Get the full symbol tree for the file:

mcp__lsp__list_symbols
  file_path: "/abs/path/to/file.go"

This returns all functions, types, variables, constants, and methods defined in the file — including nested symbols (methods on types, fields in structs).

Use this to:

  • Understand the file's structure before editing
  • Find the exact position of a named symbol
  • See what a file exposes before reading it in full

Reading the output: Each symbol has a range (full body including braces) and a selectionRange (just the name). Coordinates are 1-based. Use selectionRange.start.line and selectionRange.start.character as inputs to get_document_highlights and inspect_symbol.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

lsp-local-symbols is a skill published in the GitHub repository blackwell-systems/agent-lsp (124 stars, last pushed yesterday), licensed MIT. It adds 54 tokens to every session and 1,354 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
