description	Use when reviewing Atmos infrastructure repositories, evaluating IaC structure, or assessing components/stacks organization for quality and best practices

Atmos Repository Review

Overview

Structured review of Atmos infrastructure repositories with file-based analysis and implementation planning.

Core principle: Analysis and plans are ALWAYS persisted to files, even on re-reviews. Never skip writing files.

When to Use

• Reviewing an Atmos components or stacks repository
• Evaluating Terraform/OpenTofu infrastructure organization
• Assessing IaC repository for Atmos best practices
• Onboarding to understand existing Atmos setup
• Re-grading after improvements (creates fresh analysis.md and plan.md)

When NOT to Use

• Reviewing a single Terraform module that is not part of an Atmos repo
• General Terraform code review without Atmos structure concerns
• Reviewing Helm charts, Kubernetes manifests, or non-IaC code
• Quick one-off questions about Atmos configuration syntax
• The user explicitly asks for a non-structured review or casual feedback

Workflow

Explore -> Questions (skip if known) -> Evaluate -> Write analysis.md -> Write plan.md
  -> Ask User: [proceed | stop | edit plan] -> Review Plan -> Execute Step by Step

Critical Rules

1. ALWAYS write analysis.md — Even on re-reviews, create fresh analysis
2. ALWAYS write plan.md — Even if no P0 issues, document P1/P2 improvements
3. ALWAYS ask user before executing — Never auto-proceed to execution
4. Show the user what was written — Summarize key findings after writing files

Workflow Steps

1. Explore Repository

Use Glob, Read, and file exploration to understand structure. Check for: atmos.yaml, stacks/, components/terraform/, catalog/, CI/CD config, version constraints, provider/backend files, pre-commit hooks, terraform-docs setup, release tooling, and per-component versioning strategy.

Identify repo type: components-only, stacks-only, or monorepo.

2. Ask Clarifying Questions

On first review, ask 10-15 questions covering architecture, scale, operations, development, and governance. Skip on re-review if context is known. See templates.md for question categories.

3. Evaluate Against Criteria

Score 10 dimensions on a 1-5 scale (structure, environments, DRY, naming, layering, security, operability, scalability, CI/CD, blast-radius). See scoring-rubric.md for full rubric and grading scale (A-F).

4-5. Write analysis.md and plan.md

Write both files to <repo-root>/claude/atmos-repo-review/. Use templates from templates.md. Check findings against red-flags-reference.md.

6. Ask User to Confirm

Present grade summary and offer three choices: proceed, stop, or wait for edits.

7-8. Review Plan and Execute

Re-read plan.md for user edits, clarify ambiguities, then execute step by step. Announce each step, show changes, update verification checkboxes, and stop on failures.

Common Mistakes

Mistake	Why It Matters	What to Do Instead
Skipping file writes on re-review	Loses audit trail; user expects fresh files each time	Always write both analysis.md and plan.md
Auto-executing the plan	User may want to edit plan.md first	Always ask and wait for confirmation
Scoring without exploring fully	Leads to inaccurate grades and missed issues	Check all directories, CI config, and gitignore before scoring
Ignoring repo type distinction	Components-only repos have different expectations than monorepos	Identify repo type in Phase 1 and adjust criteria accordingly
Missing provider/backend nuance	Atmos generates override files at deploy time	Consult red-flags-reference.md for commit rules

Supporting Files

• templates.md — Output templates, question categories, confirmation prompt
• scoring-rubric.md — Evaluation dimensions and grading scale
• red-flags-reference.md — Red flags, provider/backend rules, quick reference
