agent-first-screenshots

Agent-first screenshots — an agent drives the real app via CDP and produces clean, defect-free product screenshots (newsletters, landing pages, social, decks, PR). Dual-channel verification (DOM + pixels + vision) in a capture loop. Use for any "take/redo screenshots of the app" task.

Quality

Content

100%

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

The body is a tight, actionable playbook: concrete commands and thresholds, a clearly sequenced verification loop with feedback recovery, and well-signaled references to real bundled scripts. It assumes Claude's competence and adds only non-obvious domain judgment.

DimensionReasoningScore

Conciseness

The body is information-dense with no concept explanations Claude already knows; every section (Zero-Defect Bar, Golden Rules, three-channel verification, Beautify, failure-mode table, anti-patterns) earns its tokens with actionable specifics rather than padding.

3 / 3

Actionability

Provides fully executable guidance: `location.reload()`, a CDP metrics override (1440x900, deviceScaleFactor: 2), concrete variance thresholds (>200 / <50 / bgRatio > 0.97), a vision JSON rubric, and a copy-paste `node scripts/beautify.mjs` invocation with flags — all referencing real bundled scripts.

3 / 3

Workflow Clarity

The capture loop is clearly sequenced (clean reload → navigate UI → leaf cleanup → verify → capture) with explicit validation checkpoints across all three channels and a feedback loop ('If any_obvious_defect is true ... Diagnose, fix the root cause ... recapture').

3 / 3

Progressive Disclosure

SKILL.md is a well-sectioned overview that signals one-level-deep references to real bundle files (`screenshot-verify.mjs`, `capture-verify.mjs`, `scripts/beautify.mjs`, all present in scripts/) at the relevant points, keeping full script contents out of the main file.

Description

100%

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

The description is third-person, concise, and hits all four dimensions squarely: concrete actions, natural trigger terms, explicit what-and-when guidance, and a distinct niche. It is an exemplar of the form with no padding or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'drives the real app via CDP', 'produces clean, defect-free product screenshots (newsletters, landing pages, social, decks, PR)', and 'Dual-channel verification (DOM + pixels + vision) in a capture loop' — matching the anchor for listing several specific concrete actions.

3 / 3

Completeness

Clearly answers both what (drives app via CDP, produces defect-free screenshots, dual-channel verification) and when ('Use for any "take/redo screenshots of the app" task'), with an explicit trigger clause.

3 / 3

Trigger Term Quality

The explicit trigger 'Use for any "take/redo screenshots of the app" task' uses exactly the natural phrasing a user would say when they need this skill, with good coverage of the common variations (take/redo screenshots of the app).

3 / 3

Distinctiveness Conflict Risk

The coined 'agent-first screenshots' niche with CDP plus DOM/pixel/vision verification is a clear, distinct framing unlikely to trigger for the wrong skill.
