Conciseness

The body is lean and command-centric with no explanations of concepts Claude already knows, but time-sensitive version details sit inline rather than in a compatibility/deprecated section: "Applies to Domino 6.3 and Domino Cloud", "A CLI older than 6.2.3 uses a retired authentication client", "CRAN `domino` 0.3.1 (2017)". Not 5 because the rubric explicitly penalizes inline version/date information; not 3 because nothing else is padded or over-explained.

Actionability

Fully executable, copy-paste-ready commands cover the common cases: headless install (`apt install openjdk-8-jre-headless`, `wget ... -O /tmp/domino-install-unix.sh`), both login flows, an annotated everyday-workflow block, dataset commands with flags and tuning env vars, and a complete R snippet. Not 4: there are no pseudocode or missing-key-detail gaps; the only placeholders (owner/project, <domino-url>) are inherently user-specific.

Workflow Clarity

Install/sign-in is a clear numbered sequence with a fallback and an expiry-retry loop ("The code expires quickly; rerun the command for a new one"), but the skill's destructive and batch operations lack validation checkpoints: "rm -rf .domino then domino restore (force-restore)" has no verification step, and bulk uploads note the ~1,000-file timeout and Overwrite risk without any post-upload verification. Per the rubric's explicit cap, destructive/batch workflows without validation cannot score above 3; not 4 because that cap takes precedence over the otherwise clear sequencing.

Progressive Disclosure

Good overview structure with clearly signaled, one-level-deep references ("Full install notes, OS support and proxies: [CLI-INSTALL.md]", "Every command, flag and example: [CLI-REFERENCE.md]", "Exported functions, signatures and limits: [R-PACKAGE.md]") plus a Related skills section. Not 5: none of the three referenced bundle files actually exist in the skill directory, so the navigation dead-ends; not 3 because the references are well signaled and the content split is appropriate (no bulk reference material inlined).

Specificity

Lists multiple concrete actions with comprehensive coverage: "installing the CLI graphically or headless on Linux, signing in with a browser or the device-code flow over SSH, working on a Domino File System project from a laptop, large uploads to Datasets, downloading run results, moving a project between deployments, force-restoring a broken local project, and proxy settings in domino.vmoptions", plus enumerated subcommands for both the CLI and the R package. Not 4: coverage spans the tool's whole surface with no notable gaps, matching the 5 anchor rather than 'several actions with minor gaps'.

Completeness

Explicitly answers both questions: the first two sentences state what the skill does (specific commands and covered tasks), and "Use when the user mentions..." gives concrete when-triggers. This mirrors the rubric's 5 anchor structure exactly; not 4 because the 'when' clause is already explicit and specific rather than needing more precision.

Trigger Term Quality

The trigger clause "Use when the user mentions the Domino CLI, a `domino` shell command, syncing project files from a laptop, the Domino R package, or running Domino jobs from R or a terminal" covers the natural phrasings a user would say, including command-name and console variants. Not 4: no obvious natural term is missing for this niche; file extensions don't apply to a CLI tool, so the 5 anchor's extension criterion is satisfied vacuously.

Distinctiveness Conflict Risk

Clear niche with explicit exclusions ("Not the `dom` SSH tool kit and not python-domino") that disambiguate the closest confusable tools. Not 5: covered tasks like "large uploads to Datasets" and "downloading run results" overlap with closely related sibling skills (domino-datasets, domino-jobs) referenced in the same library, leaving minor overlap risk, which is the 4 anchor.
