stitched-full-page-capture

Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

Quality

Content

92%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.

An exemplary SKILL.md body: concrete commands and parameters throughout, a well-sequenced workflow with rejection criteria and a real validation loop, and a clean split between overview and the bundled script. The only improvement space is trimming the slight overlap between Overview and Notes and the duplicated CLI defaults.

DimensionReasoningScore

Conciseness

Lean and efficient with no explanation of concepts Claude already knows, but minor instances could be trimmed: the Notes section partially restates the Overview's scroll-video caveat, and the options block duplicates the script's own CLI defaults ('--viewport 1440x1100 # default', '--step 950', '--wait 2000'). Fits 'efficient; minor instances of over-explanation' rather than 'every token earns its place'.

4 / 5

Actionability

Fully executable guidance: a copy-paste-ready node invocation with the manifest argument, concrete option flags with defaults, parameterized workflow steps (viewport-sized overlapping steps, ~2s settle wait), and runnable validation commands (sips, git diff --check, node checks, ffprobe).

5 / 5

Workflow Clarity

A clear 9-step sequence (warm-up scroll, return to top, stepped scrolling, settle, capture, stitch, crop, validate) plus explicit rejection criteria for bad candidates and a dedicated Validation section with executable checks — an explicit feedback loop for what is a batch repair operation.

5 / 5

Progressive Disclosure

The body is a well-organized ~75-line overview with clear section headers; the single bundle script (scripts/stitch_full_page_capture.mjs, verified to exist) is referenced with an exact path and summarized rather than inlined, and there are no nested or buried references.

Description

95%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: third-person, concise, concrete about both capability and trigger conditions, with rich natural failure-mode vocabulary. The only minor gap is that the stitching technique and validation workflow are not named, leaving coverage slightly short of comprehensive.

DimensionReasoningScore

Specificity

Lists several concrete actions — 'Capture or repair reliable full-page screenshots' plus deriving 'article evidence/section crops' from the result — for a well-specified domain ('lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages'). Not a 5 because the stitching method itself and validation are not named; not a 3 because it covers more than 1-2 generic actions with concrete failure modes.

4 / 5

Completeness

Explicitly answers both 'what' ('Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages') and 'when' via a concrete 'Use when...' clause enumerating specific trigger conditions. Matches the anchor for a clear what-and-when with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural phrasing a user would actually say: 'full-page screenshots', 'blank, gray, white, sparse', 'tiny content strip', 'Framer', 'lazy-loaded', 'scroll-animated', 'WebGL/canvas', 'section crops', 'scroll video' — covering synonyms and multiple failure-mode descriptions.

5 / 5

Distinctiveness Conflict Risk

Clear niche (full-page screenshot capture/repair for lazy/animated pages) with distinct symptom-based triggers ('blank, gray, white', 'disagree with a working scroll video'); minimal risk of triggering the wrong skill.
