The body is lean and operational — it does not explain what OMERO, BlitzGateway, or libraries are, and every section (Operating Contract, Install, Credentials, Helpers, Capability Guide) carries actionable load. It is tighter than the level-2 anchor that pads with "good library" justifications, and assumes Claude's competence throughout.

It provides copy-paste-ready, executable guidance: the `uv venv`/`uv pip install` install block, a complete exception-safe BlitzGateway Python snippet with try/finally, and concrete `python -B scripts/*.py --help` commands. This matches the level-3 anchor of fully executable, specific examples rather than pseudocode.

Risky remote and write workflows are clearly sequenced with explicit checkpoints: the eight-step Operating Contract, dry-run-by-default/`--execute` gating, the numbered Final Review checklist, and "Do not connect until the user has selected..." validation before remote work. This exceeds the level-2 anchor where validation is implicit.

The SKILL.md is an overview with well-signaled one-level-deep references — the Capability Guide maps each topic to a real file in references/ (connection, data_access, metadata, image_processing, rois, tables, scripts, advanced, sources), and helpers live in scripts/, all verified to exist. This matches the level-3 anchor of an overview pointing cleanly to split reference files.

The description enumerates concrete actions and surfaces — "inspect and automate microscopy data workflows," "tables, annotations, ROIs, rendering," "scoped OMERO inventory, metadata export, import/export planning" — matching the anchor that lists multiple specific concrete actions.

It states both what the skill does ("Securely inspect and automate microscopy data workflows against OMERO.server...") and when to use it via an explicit "Use for scoped OMERO inventory, metadata export, import/export planning, or reviewed write workflows" clause, satisfying the level-3 anchor for an explicit trigger.

It surfaces natural terms an OMERO user would actually say — "OMERO inventory," "metadata export," "import/export planning," "annotations," "ROIs" — giving good coverage rather than only internal jargon. It is not the level-2 anchor of a single keyword phrase because multiple natural trigger variations are present.

OMERO.server microscopy integration is a clearly defined niche with distinct triggers, making it unlikely to fire for unrelated skills. It is well above the level-2 "could still overlap" anchor because no other common skill targets this domain.
