Contributing to the Terraform Skill

We appreciate contributions to TerraShark. Every change should improve Terraform/OpenTofu output quality while staying lean on token usage.

Contribution Principles

Every change should answer three questions:

Which failure mode does this prevent? — must map to at least one of the five failure modes
What measurable quality gain does it provide? — demonstrate improvement
Is the token cost justified? — every line must earn its place

Development Flow

Create a branch
Make focused changes
Run local checks
Open PR using .github/PULL_REQUEST_TEMPLATE.md

Local Checks

# Quick sanity checks
rg -n "FIXME|placeholder-text" README.md SKILL.md references/*.md
python - <<'PY'
from pathlib import Path
assert Path('SKILL.md').exists()
assert Path('README.md').exists()
for p in [
  'references/identity-churn.md',
  'references/secret-exposure.md',
  'references/blast-radius.md',
  'references/ci-drift.md',
  'references/compliance-gates.md',
]:
  assert Path(p).exists(), f'missing {p}'
print('basic structure OK')
PY

Content Rules

Keep examples original and clearly distinct
Prefer failure-mode framing over generic "best-practice dump" text
Avoid provider-specific deep dives unless they directly reduce a known LLM failure mode
Keep claims precise; avoid vague "always" language when tradeoffs exist

Required for PR Approval

Clear mapping to one or more failure modes
No contradictory guidance across references
Updated links/indexes if files were moved/renamed
Validation workflow passing (.github/workflows/validate.yml)

Security

Never commit credentials, tokens, or secret values
Do not paste real state snippets containing sensitive data
