Use when implementing or reviewing a provider's Configure method or provider schema, adding authentication options (API keys, tokens, profiles, credentials files, assume-role), deciding how a provider should resolve credentials, debugging "no valid credential sources" or missing-credentials errors, or unit testing credential resolution.” [HashiCorp · upstream description ↗](https://github.com/hashicorp/agent-skills/blob/f706481af9b8fedb66de909f6243ad29601afa0c/plugins/terraform/skills/provider-configuration/SKILL.md) Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - The inspected headings include a credential provider chain and diagnostics that name every source tried. - A separate heading covers secret hygiene rather than leaving credentials in error strings. ### A good fit for - Implementing provider authentication - Reviewing a Configure method before submission - Resolve multi-field credentials without mixing keys from one source and secrets from another. - Reject unknown credential values before a fallback chain selects a different identity. ### Weigh up before choosing - MPL-2.0 is file-level copyleft for a modified redistribution of this file. - Examplecloud is a demonstrative API; the sample credential chain needs target-service adaptation and tests. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - plugins/terraform/skills/provider-configuration/SKILL.md - README.md - LICENSE - plugins/terraform/skills/provider-configuration/references/credential-chain.md ### Our findings - Headings include The Credential Provider Chain and Secret Hygiene. - Frontmatter name is provider-configuration. - Credential-chain reference distinguishes incomplete/missing input from malformed explicitly selected files/profiles. - The chain returns a complete credential set and records source failures for diagnostics. - A credentials file with loose permissions gets a warning that suggests chmod 0600, except on Windows where the bits are not meaningful. - Unknown-value guards prevent apply-time credential expressions from being mistaken for empty input and silently falling through to another identity. ### Not established by this review - The skill was not executed inside a host agent. - Not executed: it was not installed or run. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Add a skill to your workflow.

This short command follows the current upstream version; the review covers the revision shown above. Optional: install the reviewed revision Keeps the original source and installer version where recorded, while leaving your AI tools and installation scope for you to choose. npx skills@1.7.1 add https://github.com/hashicorp/agent-skills/tree/f706481af9b8fedb66de909f6243ad29601afa0c/plugins/terraform/skills/provider-configuration --skill provider-configuration Copy reviewed-revision command ↗ - Choose your AI tools and project or global installation scope in Skills CLI. The review applies to the source revision shown on this page. - Retain all supporting files; separately configure companion skills, runtimes and service credentials named in the definition. - Review the resulting diff and use an isolated target before any migration, deployment, load test or warehouse operation. ### Before you start - Go and Terraform Plugin Framework; synthetic credentials for local tests and scoped credentials only for authorized integration checks. ### Compatibility Agent Skills-compatible hosts · Terraform Plugin Framework ### Local Markdown instructions - Read the installed skill files - Reads environment, credential profiles and potentially platform identity; configure-time validation may call the API. ### Cost model Source is free to read under the stated licence. A host agent may charge for use. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource.
