Discovery
75%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 well-structured with a clear 'Use when' clause and targets a specific niche (Pulumi ComponentResource). Its main weakness is that the capability descriptions are somewhat high-level rather than listing concrete actions, and it could include more natural trigger term variations that users might use when seeking help with Pulumi components.
Suggestions
Add more specific concrete actions like 'define component inputs/outputs, register child resources, generate multi-language SDKs, publish to package registries'.
Include additional trigger term variations such as 'custom resource', 'resource provider', 'component schema', 'Pulumi SDK generation', or 'multilang component' to improve matching.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Pulumi ComponentResource classes) and some actions (authoring, creating reusable infrastructure components, designing interfaces, setting up multi-language support, distributing packages), but these are somewhat high-level and not deeply concrete actions like 'define inputs/outputs schemas' or 'implement resource registration'. | 2 / 3 |
Completeness | Clearly answers both 'what' (guide for authoring Pulumi ComponentResource classes) and 'when' (explicit 'Use when' clause covering creating reusable components, designing interfaces, multi-language support, and distributing packages). | 3 / 3 |
Trigger Term Quality | Includes relevant terms like 'Pulumi', 'ComponentResource', 'infrastructure components', 'multi-language support', and 'component packages', but misses common user variations like 'custom resource', 'resource provider', 'IaC component', 'Pulumi SDK', or 'component schema'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche targeting Pulumi ComponentResource classes specifically, which is unlikely to conflict with general IaC skills, Terraform skills, or other Pulumi-related but non-component skills. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a thorough, highly actionable skill with excellent executable code examples across multiple languages and clear anti-pattern guidance. Its main weaknesses are verbosity (repeated patterns, explanations of concepts Claude knows, inline content that could be in referenced files) and missing validation/testing checkpoints in the multi-language packaging and distribution workflows. Trimming explanatory prose and splitting detailed reference material into linked files would significantly improve it.
Suggestions
Remove explanatory 'Why' paragraphs and the 'When to Use This Skill' section — Claude can infer when to apply the skill from its content and description.
Split multi-language entry points and distribution details into separate referenced files (e.g., MULTI_LANG.md, DISTRIBUTION.md) to reduce the monolithic size.
Add explicit validation/testing steps to the multi-language and distribution workflows (e.g., 'Run pulumi preview to verify component works before publishing', 'Test SDK generation locally with pulumi package gen-sdk').
Deduplicate the SecureBucket example which appears in both 'Use Defaults for Optional Properties' and 'Sensible Defaults with Override' sections.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is comprehensive but verbose for its target audience (Claude). Sections like 'When to Use This Skill' and explanations of why patterns are wrong (e.g., 'Without registerOutputs(), the component appears stuck') explain things Claude likely already knows. The repeated SecureBucket pattern appears twice. However, the code examples are well-targeted and the anti-patterns table is efficient. | 2 / 3 |
Actionability | Excellent actionability throughout — full executable TypeScript and Python examples, concrete bash commands for distribution, complete GitHub Actions workflow, and specific code showing both wrong and right patterns. Every section provides copy-paste ready code. | 3 / 3 |
Workflow Clarity | The component anatomy section clearly sequences the four required steps, and the distribution section provides clear paths. However, the multi-language packaging workflow lacks explicit validation checkpoints — there's no 'verify your component works before publishing' step, no testing guidance, and no feedback loop for catching serialization constraint violations before consumers hit them. | 2 / 3 |
Progressive Disclosure | The skill references related skills (pulumi-best-practices, pulumi-automation-api) and external URLs, which is good. However, the content is monolithic at ~450+ lines with detailed code examples for multiple languages, design patterns, distribution methods, and multi-language setup all inline. The multi-language entry points section and distribution details could be split into separate reference files. | 2 / 3 |
