Lsp Edit Export

What it does

When your agent uses it

• Changing a function signature
• Modifying a public type
• Altering any symbol used outside its own package — finds all callers first so nothing breaks silently

Example prompts

• “/lsp-edit-export”

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__go_to_symbol, mcp__lsp__open_document, mcp__lsp__find_references, mcp__lsp__get_diagnostics, mcp__lsp__run_build, mcp__lsp__replace_symbol_body, Edit, Write

Workflow steps

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

1. 1Locate the symbol
2. 2Discover all callers
3. 3Confirmation gate (REQUIRED — never skip)
4. 4Make the edit
5. 5Check diagnostics
6. 6Run the build
7. 7Report

What it can do on your machine

Read from SKILL.md and the folder at commit 6fa5faf. 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__go_to_symbol
  • mcp__lsp__open_document
  • mcp__lsp__find_references
  • mcp__lsp__get_diagnostics
  • mcp__lsp__run_build
  • mcp__lsp__replace_symbol_body
  • Edit
  • Write

  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 Edit Export loads about 1.9k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 713 words of instructions outside code blocks.

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

~61

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

~1.9k

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

~2.4k

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.

## Impact Check: <SymbolName>

- Definition: <file>:<line>
- Callers found: N reference(s) in M file(s)

Files with callers:
  - <file1>
  - <file2>
  ...

Proceed with the edit? [y/n]

mcp__lsp__replace_symbol_body({
  "file_path": "<definition file>",
  "symbol_path": "ExportedFunction",
  "new_body": "<new full definition>"
})

mcp__lsp__get_diagnostics({
  "file_path": "<definition file>"
})

mcp__lsp__run_build({

})

## Edit Summary
- Symbol: <name> (<kind>)
- Callers found: N in M files
- Diagnostics: net +N/-N
- Build: PASSED / FAILED

Goal: rename exported function `ParseConfig` → `LoadConfig` in pkg/config

Step 1 — go_to_symbol: symbol_path="config.ParseConfig"
  → pkg/config/parser.go:42:6

Step 2 — find_references: position_pattern="func @@ParseConfig("
  → 7 references in 4 files

Step 3 — gate:
  ## Impact Check: ParseConfig
  - Definition: pkg/config/parser.go:42
  - Callers found: 7 in 4 files
  Files: cmd/main.go, internal/app.go, internal/loader.go, pkg/config/parser_test.go
  Proceed? [y/n] → y

Step 4 — edit: rename declaration + all 7 call sites

Step 5 — diagnostics: net 0 (no new errors)

Step 6 — build: PASSED

Step 7 — report:
  ## Edit Summary
  - Symbol: LoadConfig (function)
  - Callers found: 7 in 4 files
  - Diagnostics: net 0
  - Build: PASSED
