Terraform Docs

terraform-docs

Official terraform-docs CLI documentation synced from terraform-docs/terraform-docs/docs.

Use this skill for the terraform-docs tool that generates documentation from Terraform modules. This is not the HashiCorp Terraform language/provider/state/backend documentation; for Terraform core behavior, use Terraform's official docs instead.

Content Scope

The upstream docs tree contains 42 Markdown files and is cleanly organized. This skill syncs all docs/**/*.md:

• references/user-guide/ — installation, introduction, configuration file, formatter, sections, output behavior, recursive modules, sorting, settings, content/header/footer, output-values, version.
• references/reference/ — CLI command reference and output formats: markdown, asciidoc, json, yaml, toml, xml, pretty, tfvars hcl/json.
• references/how-to/ — configuration file usage, GitHub Action, pre-commit hooks, include examples, insert output to file, ignore resources, recursive submodules, false CLI flags, visibility of sections, generate tfvars.
• references/developer-guide/ — contributing and plugin development.

Only Markdown docs are included; repository source, examples outside docs/, images, releases, and generated artifacts are not bundled.

Hard Rules

• MUST search references/ before giving terraform-docs CLI flags, config keys, formatter names, output modes, output formats, recursive behavior, section visibility, hooks, or GitHub Action guidance.
• MUST distinguish terraform-docs CLI behavior from Terraform core behavior such as HCL syntax, provider schemas, backend/state, terraform plan, or terraform apply.
• MUST call out the output format when relevant: markdown table, markdown document, asciidoc, json, yaml, toml, xml, pretty, tfvars hcl, or tfvars json.
• NEVER invent .terraform-docs.yml keys, CLI flags, formatter names, output-mode values, or plugin behavior without checking references.

Reference Map

• references/user-guide/introduction.md — usage model and generated documentation basics.
• references/user-guide/configuration.md — .terraform-docs.yml overview.
• references/user-guide/configuration/*.md — configuration details.
• references/reference/terraform-docs.md — CLI command reference.
• references/reference/markdown-table.md and markdown-document.md — common Markdown formatters.
• references/how-to/insert-output-to-file.md — README injection workflows.
• references/how-to/pre-commit-hooks.md and github-action.md — automation integrations.
• references/developer-guide/plugins.md — plugin development.

Workflow

1. Identify whether the question is CLI usage, config file, output format, output injection, automation, recursion, filtering/sections, or plugin development.
2. Search the relevant reference subtree and format-specific page.
3. Prefer exact documented CLI flags, config keys, formatter names, and output.mode semantics.
4. Redirect Terraform core questions to Terraform language/provider docs when terraform-docs is not the source of truth.
