You are a Senior Code Reviewer. Review this completed task for code quality.

## What Was Implemented

Created `.dockerignore` to keep the Docker build context lean and prevent secrets from leaking into the image.

## Requirements / Plan

Task 4: Create `.dockerignore` at project root. Exclude node_modules, .next, .git, .env*, test files, coverage, .eslintcache, docs, *.md.

## Git Range to Review

**Base:** 5705f6b33f89027aeead0b8d5f899e376e3cae9c
**Head:** run `git -C /Users/steve.briggs/projects/churn-renewal-forecast rev-parse HEAD`

```bash
git -C /Users/steve.briggs/projects/churn-renewal-forecast diff --stat 5705f6b33f89027aeead0b8d5f899e376e3cae9c..HEAD
git -C /Users/steve.briggs/projects/churn-renewal-forecast diff 5705f6b33f89027aeead0b8d5f899e376e3cae9c..HEAD
```

Also consider: are there any other files in the project root that should be excluded from Docker but aren't in the list? Check `ls /Users/steve.briggs/projects/churn-renewal-forecast` to see what's there.

## Output Format

### Strengths
### Issues (Critical / Important / Minor)
### Assessment: Ready to merge? Yes | No | With fixes


- obsidian-load: Load context from Obsidian notes in the `Claude/` directory into the current conversation.
- obsidian-save: Save current conversation context to an Obsidian note under the `Claude/` directory.
- mind:search: Search memories for specific content or patterns
- mind:stats: Show memory statistics and storage information
- mind:ask: Ask questions about memories and get context-aware answers
- mind:recent: Show recent memories and activity timeline
- mind:memory: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- mind:mind: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code
- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements
- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints
- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code
- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring Skill tool invocation before ANY response including clarifying questions
- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment
- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a pull request
- security-review: Complete a security review of the pending changes on the current branch


I'll review this task systematically. Let me first check the current HEAD and compare the changes.


Now let me check the diff and also examine the project root to assess what should/shouldn't be excluded.


Bash

git diff --stat 5705f6b33f89027aeead0b8d5f899e376e3cae9c..HEAD

Let me also check if there's a Dockerfile to understand the context:


ls -la /Users/steve.briggs/projects/churn-renewal-forecast/*.* | grep -i docker


.rw-r--r-- steve.briggs staff 412 B  Mon May 18 16:11:28 2026 /Users/steve.briggs/projects/churn-renewal-forecast/docker-compose.yml


Let me check if there's a Dockerfile:


find /Users/steve.briggs/projects/churn-renewal-forecast -maxdepth 1 -name "Dockerfile*" -o -name ".dockerignore"


Let me read the created .dockerignore file to review it:


1	node_modules
2	.next
3	.git
4	.env*
5	**/__tests__
6	**/*.test.ts
7	**/*.test.tsx
8	coverage
9	.eslintcache
10	docs
11	*.md
12


Now let me check what common project files exist that might be candidates for exclusion. Let me also read the git status to see if there are other common artifacts:


1	# dependencies

Perfect. Now let me check if there are any hidden directories that might need to be excluded:


(Bash completed with no output)


.
./.claude
./.config
./.git
./.github
./.next
./deploy
./docs
./node_modules
./prisma
./scripts
./src


Excellent. Now I have a complete picture. Let me create my review:

## Code Review

### Strengths

1. **Comprehensive file exclusions** - The `.dockerignore` correctly excludes all the major artifacts that don't belong in a Docker image:
   - `node_modules`, `.next`, `.git` - standard build outputs and VCS metadata
   - `.env*` - secrets and environment files (critical for security)
   - Test files (`**/__tests__`, `**/*.test.ts`, `**/*.test.tsx`) - not needed in production
   - Build artifacts (`coverage`, `.eslintcache`)
   - Documentation (`docs`, `*.md`)

2. **Security-conscious** - The use of `.env*` pattern properly catches `.env`, `.env.local`, `.env.production.local`, etc., preventing secrets from leaking into the image.

3. **Clean implementation** - Single file created with straightforward patterns. No unnecessary complexity.

### Issues (Critical / Important / Minor)

**Important:** Two categories of files exist at the project root that should likely be excluded but aren't:

1. **Configuration files used only for development** (not imported at runtime):
   - `.eslintcache` is excluded (good), but related files should be considered
   - `vitest.setup.ts`, `vitest.config.ts`, `eslint.config.mjs` - These are dev-only tooling configs that aren't needed in the final Docker image

2. **Runtime-irrelevant files that bloat the build context**:
   - `.nvmrc`, `.npmrc` - Package manager version/config files (not used by Node runtime)
   - `.worktreeinclude` - Git worktree metadata (unnecessary)
   - `docker-compose.yml` - Docker Compose config (rarely needed in the image itself)
   - `.env.example` - Documentation/template file (covered by `*.md` pattern, but `.example` isn't `.md`)
   - `worker.log` - Temporary logs from development
   - `bun.lock` - The lockfile itself (though `node_modules` is already excluded)
   - `package.json` could arguably be needed if running `npm install` in the Dockerfile, but if using multi-stage builds with pre-copied modules, it's not essential

**Decision point:** The question is whether to include everything matching the requirement or optimize further. The task requirement specifies: "Exclude node_modules, .next, .git, .env*, test files, coverage, .eslintcache, docs, *.md." The current implementation **does meet the stated requirements exactly**.

However, best practice for a lean Docker build context would additionally exclude the dev-only files listed above. Since no Dockerfile exists in the repo yet, and Docker practices may vary, this is a minor enhancement opportunity rather than a critical issue.

### Assessment: Ready to merge? **Yes**

The `.dockerignore` file meets the stated requirements comprehensively. It correctly excludes all specified categories and addresses the security concern of preventing `.env` files from entering the image.

The file could be enhanced with additional development-only artifacts for an even leaner Docker context, but that's outside the stated scope and can be addressed in future refinement if/when a Dockerfile is added to the project.
