cloudformation-to-pulumi

Convert, migrate, or import AWS CloudFormation stacks or templates into Pulumi programs. Load this skill whenever a user wants to move from CloudFormation to Pulumi, convert a CFN template, import existing CloudFormation-managed resources into Pulumi, or asks about CloudFormation-to-Pulumi migration in any form. Also load when the user mentions cdk-importer in a migration context.

Content

77%

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

The body is highly actionable with a well-sequenced, validated workflow, but loses points for restated critical rules and, more importantly, for referencing two bundle files that are not actually present, which undermines progressive disclosure.

Suggestions

Add the missing referenced files (cfn-importer.md and cloudformation-id-lookup.md) to a references/ directory, or inline the needed detail and remove the broken links.

Consolidate the repeated 'use CloudFormation Logical ID as resource name' and 'use aws-native by default' rules into a single authoritative section instead of restating them across CRITICAL SUCCESS REQUIREMENTS, the conversion subsections, and Pre-Import Validation.

Move the large intrinsic-function mapping table and per-function code examples into a reference file to shorten SKILL.md and improve progressive disclosure.

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's competence, but two critical rules (use Logical ID as resource name; use aws-native by default) are each restated across three sections with decorative emphasis (e.g. '⚠️ CRITICAL ⚠️'), so it could be tightened rather than earning the fully lean top anchor.

2 / 3

Actionability

Provides copy-paste-ready bash commands, complete TypeScript examples for intrinsics/parameters/mappings/conditions, and a resource-mapping table, matching the 'fully executable, copy-paste ready' anchor rather than the incomplete/pseudocode 2.

3 / 3

Workflow Clarity

A clearly numbered workflow with explicit validation checkpoints (Pre-Import Validation, post-import preview) and a feedback loop ('investigate and update the program until preview is clean') matches the top anchor for sequenced steps with validation.

3 / 3

Progressive Disclosure

Two references are clearly signaled one level deep (cfn-importer.md, cloudformation-id-lookup.md), but neither file exists in any bundle directory, so navigation breaks; combined with a large inline intrinsic table and many inline examples that could be split out, this fits the 'structure present but references broken / content that should be separate is inline' level rather than a clean 3.

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 strong across all dimensions: it states concrete actions, provides explicit natural-language trigger guidance, answers both what and when, and occupies a distinct niche unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Enumerates multiple concrete actions (convert, migrate, import) on a specific target (CloudFormation stacks/templates into Pulumi programs), matching the 'lists multiple specific concrete actions' anchor rather than the partial coverage of a 2.

3 / 3

Completeness

Explicitly answers both what (convert/migrate/import CFN into Pulumi) and when ('Load this skill whenever a user wants to move from CloudFormation to Pulumi...'), with a clear 'Use when'-equivalent trigger, so it meets the top anchor rather than capping at 2.

3 / 3

Trigger Term Quality

Covers natural user phrasings like 'move from CloudFormation to Pulumi', 'CFN template', 'CloudFormation-to-Pulumi migration', plus the tool name 'cdk-importer', giving good coverage of terms a user would actually say.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (CFN-to-Pulumi migration) with distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor rather than the overlapping 2.
