lsp-concurrency-audit SKILL.md skillA

lsp-concurrency-audit 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-concurrency-audit@git:20261104.5790d48

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

Concurrency safety audit for a type or file. Maps all fields, traces which are accessed from concurrent contexts (goroutines, threads, async tasks), and flags fields that lack synchronization. Produces a field-level safety report. Language-agnostic across 4 concurrency families.

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-concurrency-audit

Given a type or file, map all fields, identify which are accessed from multiple
concurrent contexts, and flag fields that lack synchronization. Produces a
field-level concurrency safety report.

## When to Use

- Before refactoring a type that is accessed from goroutines/threads
- Auditing a codebase for data race candidates
- Reviewing a PR that adds concurrent access to an existing type
- Understanding which fields in a type need mutex protection

## Input

```
/lsp-concurrency-audit <file-path> [--type <TypeName>]
```

If `--type` is provided, audit only that type. Otherwise, audit all types in
the file that have concurrent callers.

## Step 1: Discover types and fields

Call `list_symbols` on the target file to enumerate all types (structs, classes):

```
mcp__agent-lsp__list_symbols({ "file_path": "<target>" })
```

For each type (kind=23 struct, kind=5 class), collect:
- Type name
- All fields (children with kind=8 field or kind=7 variable)
- Whether any field's name or detail contains sync primitives
  ("Mutex", "RWMutex", "Lock", "Semaphore", "atomic", "Atomic", "sync.",
  "pthread_mutex", "std::mutex")
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add blackwell-systems/agent-lsp/lsp-concurrency-audit@sha256:4d5baf08809aa1ff

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.
