external-attach-diagnostic SKILL.md skillA
external-attach-diagnostic from lingtai-ai/lingtai-kernel is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lingtai-ai/lingtai-kernel/external-attach-diagnostic@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Guarded macOS-only external attach diagnostic: verifies a live LingTai PID and incarnation against an exact agent directory, captures bounded /usr/bin/sample stacks plus content-free runtime facts, and optionally performs one controlled external mcp.* burst without exercising NotificationStore locking.
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
# External Attach Diagnostic Use this **only for an authorized, live macOS incident investigation** when an external observer needs bounded process stacks. It is a reusable script, not an in-process debug mode and not a timing profiler: its samples are **stacks, not semantic stage timings**. The script is at `scripts/external_attach_diagnostic.py`. Run it from a Python environment that can import the target LingTai runtime. It requires exact `--agent-dir` and `--pid`, plus an **absent** absolute `--artifact-dir`: ```bash python3 scripts/external_attach_diagnostic.py \ --agent-dir /absolute/path/to/agent \ --pid 12345 \ --artifact-dir /absolute/empty-parent/attach-20260824 ``` ## Preconditions and refusal rules 1. It is macOS-only and requires executable `/usr/bin/sample`. Unsupported host/tool failure happens **before** it creates the artifact directory or mutates the agent directory. 2. `--agent-dir` and the artifact parent must be canonical absolute directories; the artifact target itself must not exist. The script creates only that new evidence directory (mode `0700`). 3. The supplied PID is verified through the existing process-table adapter and …

How to install
mdr add lingtai-ai/lingtai-kernel/external-attach-diagnostic@sha256:011376e915e49535The line at the top of this page pins the label v1.0.0, 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.
