Paste and run these commands in a terminal with Claude Code. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Included Skills3

content-fidelityskills/content-fidelity/SKILL.md

Author a frozen text content-fidelity eval component for a project — the non-visual sibling of servo's design-eval. Use when generated text (a reply, a doc, a templated message) must match an intended rubric or spec ("does this text match the intended tone/content/style?") and that fidelity should drive or gate the loop. Gathers the generated text under test (file read or generator command), judges fidelity with a pinned text-capable model (n-sampled, lower-bound), freezes the definition, and installs a `score_content_fidelity` component into the project's `oracle.sh`. Do not use for deterministic checks (use scaffold-init / spec-oracle), for visual/UI fidelity (use design-eval), or for the per-iteration judge agent.

design-evalskills/design-eval/SKILL.md

Author a frozen UI design-fidelity eval component for a project — the non-deterministic sibling of servo's deterministic component templates. Use when a project must be built to match a design mockup ("does the UI match the design?") and that fidelity should drive or gate the loop. Captures app vs reference screenshots, judges fidelity with a pinned vision model (n-sampled, lower-bound), freezes the definition, and installs a `score_design_fidelity` component into the project's `oracle.sh`. Do not use for deterministic checks (use scaffold-init / spec-oracle) or for the per-iteration judge agent.

eval-authoringskills/eval-authoring/SKILL.md

Author a frozen text-judged eval from a spec-006 `residual_judgment` AC or a free-form goal. Guides triage, rubric shaping, reference-set collection, frozen n/δ/threshold/judge parameters, ADR-0024 freeze/install, and advisory judge audit. Use to author an eval, turn a goal into acceptance criteria, shape a rubric or reference set, freeze/install an eval, or audit judge trust. Do NOT use to run evals (`quality-gate`/`agent-loop`), classify deterministic checks (`spec-oracle`), decide EDD suitability (`edd-suitability`), or build design/content fidelity evals (use the `design-eval` / `content-fidelity` presets). This is the generic surface for other text-judged criteria.
