lsp-cross-repo SKILL.md skillA

lsp-cross-repo 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-cross-repo@git:20261104.5790d48

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

Cross-repository analysis — find all callers of a library symbol in one or more consumer repos. Use when refactoring a shared library and need to understand how consumers use it.

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.

# lsp-cross-repo

Multi-root cross-repo caller analysis for library + consumer workflows. Finds all
usages of a library symbol across one or more consumer codebases in a single call.

Read-only — does not modify any files.

## When to use

- Before changing a library API: find all callers in every consumer
- Before deleting a symbol: verify it has no cross-repo dependents
- When a change in repo A might break repo B or C
- Auditing how internal packages are used across services

Use `/lsp-impact` instead for single-repo blast-radius analysis.

## Workflow

### Step 1 — Initialize the primary workspace

Start the language server on the library root if not already running:

```
mcp__agent-lsp__start_lsp({ "root_dir": "/path/to/library" })
```

### Step 2 — Locate the library symbol

Find the symbol's definition to get `file_path`, `line`, and `column`:

```
mcp__agent-lsp__find_symbol({ "query": "<symbol-name>" })
```

Pick the result in the library repo (not a test file).

### Step 3 — Find all cross-repo references (primary step)

Call `get_cross_repo_references` with the symbol location and all consumer repo
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add blackwell-systems/agent-lsp/lsp-cross-repo@sha256:bcd14fc1d0440991

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.
