What it does

Lsp is an agent skill from LuisaGroup/LuisaCompute. clangd LSP over HTTP for C++ syntax checks and symbol navigation in LuisaCompute sources.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with C++. The repository describes itself as: High-Performance Rendering Framework on Stream Architectures. The licence is Apache-2.0.

Example prompts

  • “/lsp”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Start the server in the background before any C++ editing session
  2. Use the client to query information. Common commands

What it can do on your machine

Read from SKILL.md and the folder at commit 0c84a1a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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.

Context cost

Lsp loads about 758 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 226 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~758

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.

clangd LSP over HTTP for C++ syntax checks and symbol navigation in LuisaCompute sources.

C++ LSP

Provides clangd-powered syntax checks and symbol queries over an HTTP bridge.

Architecture

  • Server (scripts/cpp_lsp_server.py): FastAPI wrapper around clangd. Requires compile_commands.json.
  • Client (scripts/cpp_lsp_client.py): httpx CLI that talks to the server.

Workflow

  1. Start the server in the background before any C++ editing session:

    bash
    python scripts/cpp_lsp_server.py --project-root . --port 8000

    The server auto-discovers compile_commands.json in .vscode/, build/, or project root. If none is found, it falls back to the project root.

  2. Use the client to query information. Common commands:

Check Syntax
bash
python scripts/cpp_lsp_client.py check src/foo.cpp -v
# Override content ad-hoc:
python scripts/cpp_lsp_client.py check src/foo.cpp --content "int main() { return 0; }"
Symbol Navigation
bash
# Go to definition at line 10, character 5 (0-based)
python scripts/cpp_lsp_client.py symbol src/foo.cpp 10 5 --action definition

# Hover info
python scripts/cpp_lsp_client.py symbol src/foo.cpp 10 5 --action hover

# Document-level symbols
python scripts/cpp_lsp_client.py symbol src/foo.cpp --action documentSymbol

Available actions: definition, declaration, typeDefinition, implementation, references, hover, documentSymbol.

You can also override file content for symbol queries:

bash
python scripts/cpp_lsp_client.py symbol src/foo.cpp 10 5 --action hover --content "int x = 0;"
Server Health
bash
curl http://127.0.0.1:8000/health

Parameters

Client flagDefaultDescription
--serverhttp://127.0.0.1:8000Server base URL
--timeout3.0HTTP request timeout (s)
--lsp-timeout10.0Internal clangd timeout (s) passed to the server
Server flagDefaultDescription
--host / --port127.0.0.1:8000Bind address
--project-root.Where to search for compile_commands.json
--clangdclangdPath to clangd executable
--compile-commands-dirautoOverride compile_commands.json location
--verboseoffPrint LSP traffic

Exit Codes

  • check subcommand: 0 (no issues), 1 (errors found), 2 (connection/server error).
  • symbol subcommand: 0 (result returned), 1 (no result), 2 (connection/server error).

Requirements

  • clangd in PATH
  • compile_commands.json generated, e.g.:
    • XMake: xmake project -k compile_commands --lsp=clangd .vscode
    • CMake: -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
  • Python packages: fastapi, uvicorn, httpx, pydantic

Notes

  • The server holds a single clangd process. Restart it if compile_commands.json changes.
  • line and character are 0-based, matching the LSP protocol and clangd's expectations.
