Lsp Generate

What it does

When your agent uses it

• Language server code generation — implement interface stubs
• Generate test skeletons
• Add missing methods
• Generate mock types

Example prompts

• “/lsp-generate”

Requirements

• Python 3
• Compatibility (from SKILL.md): Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)
• Pre-approved tools (allowed-tools): mcp__lsp__suggest_fixes, mcp__lsp__execute_command, mcp__lsp__apply_edit, mcp__lsp__format_document, mcp__lsp__get_diagnostics, mcp__lsp__open_document, mcp__lsp__get_server_capabilities, mcp__lsp__go_to_symbol

Workflow steps

5 steps, taken from the step headings in SKILL.md.

1. 1Open document and locate position
2. 2Get code actions at target position
3. 3Select and confirm action
4. 4Execute generator
5. 5Format and verify

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__suggest_fixes
  • mcp__lsp__execute_command
  • mcp__lsp__apply_edit
  • mcp__lsp__format_document
  • mcp__lsp__get_diagnostics
  • mcp__lsp__open_document
  • mcp__lsp__get_server_capabilities
  • mcp__lsp__go_to_symbol

  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 Generate loads about 1.4k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 582 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~57

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~1.9k

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

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.
