82%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-crafted skill body: concrete, executable guidance in every section, clear start/edit/reorder workflows, and sensible delegation of SVG and manifest detail to sibling skills. The only weaknesses are mild redundancy around bundle-suffix and presentation rules and the absence of an explicit manifest-validation feedback loop.

Dimension	Reasoning	Score
Conciseness	Imperative, dense sections with real artifacts (manifest JSON, SVG starter) and zero time spent explaining concepts Claude already knows. Minor trimmable redundancy — the `.canvas`-suffix rule is stated in both Structure and Working pattern, and "Show the result" restates presentation rules several ways — so it falls just short of the lean anchor 5.	4 / 5
Actionability	Fully executable throughout: a copy-paste-ready 1920×1080 SVG starter, a complete `.canvas.json` manifest example, exact file conventions (`001.svg`, `<name>.canvas/.canvas.json`), explicit edit/reorder/add/remove operations, and concrete tool calls (`write_file`, `read_file`, `surface_open`). This matches the top anchor — specific examples cover the common cases.	5 / 5
Workflow Clarity	Start, edit, and reorder workflows are clearly sequenced with explicit pre-open guards ("Never open an empty bundle, a broken manifest, or a manifest whose first slide is missing"). It lacks a validate-then-fix feedback loop for manifest errors, so it sits at anchor 4 rather than 5; checkpoints are explicit, so it is clearly above 3.	4 / 5
Progressive Disclosure	No bundle files exist (no references/, scripts/, or assets/), and the ~110-line body is well-sectioned with clear headings; it appropriately delegates SVG authoring and manifest mechanics to sibling skills via a "See also" section rather than inlining them. At this length it stays appropriately single-file, but the template and presentation sections could plausibly be split into reference files, so it does not reach anchor 5.	4 / 5

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: it precisely defines the artifact (Grida `.canvas` slides bundle, one SVG per slide, 16:9) and pairs it with an explicit, naturally worded trigger clause. The only notable gap is that it advertises only the build action, not edit/reorder/template workflows the skill also covers.

Suggestions

Mention that the skill also covers editing, reordering, and adding slides to an existing deck, so the 'what' covers the full capability set (e.g., "Build and edit a Grida slides deck…").

Consider adding one more natural trigger variant such as a plain "deck" or "make slides" phrasing to broaden trigger coverage.

Dimension	Reasoning	Score
Specificity	Names the domain and output format concretely ("a `.canvas` bundle in slides mode whose pages are SVG documents (16:9, one SVG per slide)") but lists only a single action ("Build") — editing, reordering, or template workflows are not mentioned, so coverage is not comprehensive.	3 / 5
Completeness	Explicitly answers both questions: what ("Build a Grida slides deck — a `.canvas` bundle in slides mode whose pages are SVG documents") and when ("Use when creating a presentation, pitch deck, slideshow, or talk") with concrete trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	"Use when creating a presentation, pitch deck, slideshow, or talk" covers good natural synonyms a user would say. A few common variations ("deck" alone, "keynote", slide-count phrasing) are missing, so it falls short of comprehensive anchor 5.	4 / 5
Distinctiveness Conflict Risk	The Grida `.canvas` + SVG format niche is distinct and clearly disambiguated from other presentation formats, but the generic triggers "presentation" and "talk" carry minor overlap risk with any general pptx/presentation skill.	4 / 5
