healthcheck skillA
healthcheck is agent-read markdown (skill) from grainulation/grainulator: Check the unified Grainulator MCP server and local CLI without blocking useful work on optional connectors..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# /healthcheck — Verify the local connection Check the three capability groups exposed by the single `grainulator` server: - `grainulator.status` with the active sprint `dir`: evidence operations. No sprint found is a valid connected response. - `grainulator.memory_list`: local knowledge storage. - `grainulator.exports_formats`: document conversion. Batch independent checks where the host supports it. Distinguish an unavailable tool from a connected tool returning an application error. Report actual results; an advertised tool alone does not prove a successful call. If MCP is unavailable, run `node <checkout>/bin/grainulator.js doctor` and continue through the local CLI. Generate the intended connection with `grainulator connect --dir <sprint>`. In a plugin host, reload its registration before adding duplicates; in another host, use its supported local MCP configuration. Do not silently edit global settings. …

mdr add grainulation/grainulator/healthcheck@git:20260922.e702f49mdr add grainulation/grainulator/healthcheck@sha256:cfab3dd336aa84f7Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
