Skill: Fix End User Documentation With swissshepherd

Fix Terraform provider documentation issues by removing targets from the swissshepherd ignore list, validating findings against the schema, and correcting the documentation.

When to use

Trigger this skill when the user:

• Says "fix docs", "fixdocs", "run swissshepherd", "run ss", or similar
• Asks to remove a target from the swissshepherd ignore list
• Asks to fix documentation for a specific resource or data source
• Provides swissshepherd output and asks to fix the findings

Inputs

Optional:

• A target name (e.g., aws_s3_bucket) or prefix (e.g., aws_s3_)
• A type (resource, data_source, ephemeral, etc.)
• Number of targets to process (default: 1)

If no target is specified, pick the next one from ignore_targets in .ci/swissshepherd-weak.hcl.

Procedure

Phase 1: Verify clean baseline

make swissshepherd

This MUST output "All checks passed." before proceeding. If it doesn't, stop and tell the user the baseline is dirty.

Phase 2: Select and expose target

• Open .ci/swissshepherd-weak.hcl
• Find the target in an ignore_targets list (within a check block)
• Remove the target line from the list
• Run swissshepherd to see findings:

swissshepherd --config .ci/swissshepherd-weak.hcl --target <name> --type <type>

If "All checks passed" — the target was already clean. Commit the config removal and move to the next target.

Phase 3: Validate findings

For each finding, determine if it's valid by checking the schema source of truth:

• Coverage errors ("not documented", "does not exist in schema"): Read the resource's Go source (internal/service/<service>/<resource>.go or *_data_source.go) to confirm the attribute/block exists in the schema.
• Heading errors: Check what the heading currently says vs what ss expects.
• Label errors: Check if the attribute is Required, Optional, or Computed in the schema.
• Byline errors: Compare against the expected bylines in the config.

If a finding appears to be a swissshepherd bug (schema says one thing, ss reports another), note it and skip — do NOT fix the doc incorrectly.

Phase 4: Fix the documentation

BOTH WARNINGS AND ERRORS should be fixed!!

Open the doc file (path is in the ss output) and apply fixes:

| Finding | Fix |

|---------|-----|

| "block X is not documented" | Add a ### \block_name\ Block section with its attributes listed |

| "attribute X should be documented in Attribute Reference" | Add to Attribute Reference section |

| "attribute X should not appear in Argument Reference" | Move from Arguments to Attributes |

| "documented attribute X does not exist in schema" | Remove from docs (it's phantom) |

| "missing (Required) or (Optional) label" | Add the correct label based on schema |

| "heading ... should be ..." | Rename to the suggested heading |

| "byline does not match expected texts" | Replace with a standard byline |

| "reference-style link definition" | Convert ref]: url to inline [text |

Documentation style rules

When adding or editing documentation:

• Arguments: * \name\ - (Required) Description. or * \name\ - (Optional) Description.
• Attributes: * \name\ - Description. (no Required/Optional label)
• Descriptions start with a verb or noun — never "A ", "An ", "The ", "Specifies ", "Indicates "
• Boolean arguments: start with "Whether to..."
• Keep alphabetical order within required/optional groups
• Block sections use heading: ### block_name Block
• Byline for arguments: "The following arguments are required:" / "The following arguments are optional:"
• Byline for attributes: "In addition to all arguments above, the following attributes are exported:"

Authoritative reference: docs/end-user-documentation.md. When this skill and that document disagree, the document wins.

Phase 5: Verify fix

swissshepherd --config .ci/swissshepherd-weak.hcl --target <name> --type <type>

Must output "All checks passed." If not, iterate on remaining findings.

Phase 6: Full verification

make swissshepherd

Must output "All checks passed." to confirm no regressions.

Phase 7: Commit

Stage and commit:

git add .ci/swissshepherd-weak.hcl website/docs/
git commit -m "<resource_name>: Fix documentation per swissshepherd"

Use the resource name without the aws_ prefix in the commit message scope when it matches a single service. For multi-target batches, use the service name.

Important constraints

• Schema is truth. Never "fix" a finding by silencing it if the schema confirms the issue.
• One target per commit. Each removed ignore target gets its own commit for clean git history.
• Always use --config .ci/swissshepherd-weak.hcl — running without config produces 20,000+ findings.
• Check both check blocks. A target may appear in ignore_targets under check "schema_docs" AND check "import_section" (or others). Remove from all.
• Don't touch ignore_contents_check unless the user explicitly asks — those are structural exceptions.
• Preserve file structure. Don't rewrite entire doc files. Make minimal, targeted edits.
• Nested blocks. When ss reports "block X.Y is not documented", the doc needs a subsection under the parent block's section. Use ### y Block nested contextually after the parent.

Example session

User: "fix docs for aws_s3_bucket_lifecycle_configuration"

• Verify make swissshepherd passes
• Remove aws_s3_bucket_lifecycle_configuration from ignore_targets in the schema_docs check block
• Run swissshepherd --config .ci/swissshepherd-weak.hcl --target aws_s3_bucket_lifecycle_configuration --type resource
• See: ERROR [schema_docs] ... block "rule.filter" is not documented
• Check Go source — confirm filter block exists under rule
• Add ### filter Block section with its attributes
• Re-run ss — passes
• Run make swissshepherd — passes
• Commit
