Discovery
7%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is extremely weak—it is essentially just the skill name repeated with no explanation of capabilities, no natural trigger terms, and no guidance on when to use it. It would be nearly impossible for Claude to reliably select this skill from a pool of alternatives based on this description alone.
Suggestions
Add concrete actions the skill performs, e.g., 'Creates IAM policy bindings in Google Cloud Platform, assigns roles to members (users, service accounts, groups) on GCP resources such as projects, folders, and organizations.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user needs to grant IAM roles, create role bindings, manage GCP permissions, or assign access to service accounts, users, or groups.'
Remove the duplicate trigger term ('iam binding creator' is listed twice) and expand with varied natural phrases users might say, such as 'grant access', 'add IAM role', 'GCP permissions', 'bind role to service account'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description does not describe any concrete actions. It only names itself ('Iam Binding Creator') and mentions 'GCP Skills' but provides no detail about what it actually does—no mention of creating IAM bindings, managing permissions, assigning roles, or any specific operations. | 1 / 3 |
Completeness | The description fails to answer both 'what does this do' and 'when should Claude use it'. There is no explanation of capabilities and no meaningful 'Use when...' guidance—only a self-referential trigger clause. | 1 / 3 |
Trigger Term Quality | The trigger terms are just the skill name repeated ('iam binding creator, iam binding creator'). It lacks natural keywords users would say such as 'IAM policy', 'role binding', 'grant access', 'service account permissions', 'gcloud iam', or 'GCP permissions'. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'GCP' and 'IAM Binding' provides some domain specificity that distinguishes it from generic skills, but the lack of concrete detail about what it does versus other GCP-related skills means overlap risk remains. | 2 / 3 |

Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty shell with no substantive content. It consists entirely of generic boilerplate that describes what the skill would do without actually providing any actionable guidance on creating IAM bindings in GCP. There are no gcloud commands, no Terraform examples, no API references, and no concrete instructions of any kind.
Suggestions
Add concrete, executable examples using `gcloud projects add-iam-policy-binding` or Terraform `google_project_iam_binding` resources with specific role and member syntax.
Include a clear workflow: 1) identify the resource, 2) determine the role, 3) create the binding, 4) verify with `gcloud projects get-iam-policy` — with explicit validation steps.
Remove all boilerplate sections (Purpose, When to Use, Example Triggers, Capabilities) and replace with actual technical content showing IAM binding patterns, common roles, and safety considerations (e.g., avoiding overly permissive bindings).
Add references to related documentation or companion files for advanced topics like conditional IAM bindings, organization-level policies, or custom roles.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and boilerplate. It explains nothing Claude doesn't already know, repeats 'iam binding creator' excessively, and provides zero substantive information about how to actually create IAM bindings in GCP. | 1 / 3 |
Actionability | There are no concrete commands, code examples, API calls, or specific instructions. The content is entirely abstract and descriptive—phrases like 'provides step-by-step guidance' without actually providing any guidance. | 1 / 3 |
Workflow Clarity | No workflow, steps, or sequence is defined. There are no validation checkpoints, no actual process to follow, and no mention of specific GCP CLI commands or API calls for creating IAM bindings. | 1 / 3 |
Progressive Disclosure | The content is a flat, uninformative page with no references to detailed materials, no links to examples or API documentation, and no structured navigation to deeper content. | 1 / 3 |
