aws-transform

Performs code upgrades, migrations, and transformations using the AWS Transform (ATX) CLI. Use when upgrading language versions, migrating AWS SDKs, migrating frameworks (Angular, Vue.js, Spring Boot, React), upgrading libraries, optimizing performance, migrating x86 to Graviton, analyzing codebases / generating documentation, or defining custom transformations with natural language. Runs locally on a few repositories or at scale across hundreds via AWS Batch/Fargate.

Quality

Content

88%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-structured, highly actionable skill body with clear sequenced workflow and explicit validation for destructive/batch AWS operations; its main weakness is token overhead from a verbatim marketing greeting and sizable inlined content that could live in reference files.

Suggestions

Move the verbatim marketing greeting into a short reference or trim it to a one-line user prompt to reduce context-token overhead.

Relocate the Dockerfile customization and Secrets Manager private-repo credential flows into references/remote-execution.md, keeping only the decision logic and a link in SKILL.md.

Consolidate repeated 'Do NOT' guardrail phrasing into the existing Critical Rules / Guardrails sections to cut redundancy.

Dimension	Reasoning	Score
Conciseness	Mostly efficient operational guidance that earns its place, but the verbatim marketing greeting block ('The agents modernizing the world's infrastructure...') and some repeated 'Do NOT' emphasis add tokens that could be trimmed without losing clarity.	4 / 5
Actionability	Fully executable, copy-paste-ready bash throughout — prerequisite checks, IAM policy attach script, S3 sync, Dockerfile customization, version-switcher edits, telemetry flag — covering the common cases concretely.	5 / 5
Workflow Clarity	Clear 8-step sequence with explicit validation checkpoints and feedback loops ('Do NOT proceed until ... succeeds', 'Re-run aws sts get-caller-identity after setup', confirm-before-execute), satisfying the destructive/batch validation requirement.	5 / 5
Progressive Disclosure	Good structure with a References table and inline links to 7 real one-level-deep reference files, but substantial detail (Dockerfile customization, full Secrets Manager credential flows, S3 zip handling) is inlined in SKILL.md rather than split into references.	4 / 5

Description

100%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, third-person description that concretely lists capabilities, provides an explicit 'Use when' trigger clause with natural phrases and synonyms, and carves out a distinct AWS Transform niche with minimal conflict risk.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'code upgrades, migrations, and transformations', 'upgrading language versions', 'migrating AWS SDKs', 'migrating frameworks (Angular, Vue.js, Spring Boot, React)', 'migrating x86 to Graviton', 'analyzing codebases / generating documentation', 'defining custom transformations' — giving comprehensive coverage.	5 / 5
Completeness	Explicitly states what it does ('Performs code upgrades, migrations, and transformations using the AWS Transform (ATX) CLI') and when to use it via a concrete 'Use when ...' clause enumerating trigger scenarios.	5 / 5
Trigger Term Quality	Natural user phrases are covered comprehensively with synonyms and specific names: 'upgrading language versions', 'migrating AWS SDKs', 'migrating frameworks (Angular, Vue.js, Spring Boot, React)', 'optimizing performance', 'migrating x86 to Graviton', 'defining custom transformations with natural language'.	5 / 5
Distinctiveness Conflict Risk	Clear AWS-specific niche ('AWS Transform (ATX) CLI', 'AWS Batch/Fargate', 'Graviton', named frameworks and SDK migrations) with distinct triggers and minimal overlap with other skills.	5 / 5
	Total	20 / 20 Passed
