lsp-format-code SKILL.md skillA

lsp-format-code from blackwell-systems/agent-lsp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add blackwell-systems/agent-lsp/lsp-format-code@git:20261104.5790d48

Pins git:20261104.5790d48 in mdr.lock. Pin the fingerprint instead.

Format a file or selection using the language server's formatter. Use before committing to apply consistent style, or after generating code to clean up indentation and spacing. Supports full-file and range-based formatting.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

> Requires the agent-lsp MCP server.

# lsp-format-code

Format a file or selection using the language server's formatter — the same
formatting engine your IDE uses. Applies language-specific rules (gofmt, prettier,
rustfmt, black) without requiring those tools to be on PATH separately.

## When to use

- Before committing: ensure consistent style across edited files
- After generating code: clean up AI-generated indentation and spacing
- After a refactor that shifted indentation levels
- When a linter flags style violations fixable by the formatter

Use `/lsp-safe-edit` instead when you are making a logic change and want
before/after diagnostic comparison alongside the edit.

## Workflow

### Step 1 — Check formatting is supported (optional)

If unsure whether the language server supports formatting for this file, check
capabilities first:

```
mcp__agent-lsp__get_server_capabilities({ "file_path": "<file>" })
```

Look for `documentFormattingProvider` (full-file) and
`documentRangeFormattingProvider` (range). If neither is present, the server
does not support formatting — stop and report.

Skip this step if you know the language supports formatting (Go, TypeScript,
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add blackwell-systems/agent-lsp/lsp-format-code@sha256:63e23196425c98d0

The line at the top of this page pins the label git:20261104.5790d48, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
