Once you understand what you're building, present the design and get user approval.\n\n\nDo NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.\n\n\n## Anti-Pattern: \"This Is Too Simple To Need A Design\"\n\nEvery project goes through this process. A todo list, a single-function utility, a config change — all of them. \"Simple\" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.\n\n## Checklist\n\nYou MUST create a task for each of these items and complete them in order:\n\n1. **Explore project context** — check files, docs, recent commits\n2. **Ask clarifying questions** — one at a time, understand purpose/constraints/success criteria\n3. **Propose 2-3 approaches** — with trade-offs and your recommendation\n4. **Present design** — in sections scaled to their complexity, get user approval after each section\n5. **Write design doc** — save to `docs/plans/YYYY-MM-DD--design.md` and commit\n6. **Transition to implementation** — invoke writing-plans skill to create implementation plan\n\n## Process Flow\n\n```dot\ndigraph brainstorming {\n \"Explore project context\" [shape=box];\n \"Ask clarifying questions\" [shape=box];\n \"Propose 2-3 approaches\" [shape=box];\n \"Present design sections\" [shape=box];\n \"User approves design?\" [shape=diamond];\n \"Write design doc\" [shape=box];\n \"Invoke writing-plans skill\" [shape=doublecircle];\n\n \"Explore project context\" -> \"Ask clarifying questions\";\n \"Ask clarifying questions\" -> \"Propose 2-3 approaches\";\n \"Propose 2-3 approaches\" -> \"Present design sections\";\n \"Present design sections\" -> \"User approves design?\";\n \"User approves design?\" -> \"Present design sections\" [label=\"no, revise\"];\n \"User approves design?\" -> \"Write design doc\" [label=\"yes\"];\n \"Write design doc\" -> \"Invoke writing-plans skill\";\n}\n```\n\n**The terminal state is invoking writing-plans.** Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.\n\n## The Process\n\n**Understanding the idea:**\n- Check out the current project state first (files, docs, recent commits)\n- Ask questions one at a time to refine the idea\n- Prefer multiple choice questions when possible, but open-ended is fine too\n- Only one question per message - if a topic needs more exploration, break it into multiple questions\n- Focus on understanding: purpose, constraints, success criteria\n\n**Exploring approaches:**\n- Propose 2-3 different approaches with trade-offs\n- Present options conversationally with your recommendation and reasoning\n- Lead with your recommended option and explain why\n\n**Presenting the design:**\n- Once you believe you understand what you're building, present the design\n- Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced\n- Ask after each section whether it looks right so far\n- Cover: architecture, components, data flow, error handling, testing\n- Be ready to go back and clarify if something doesn't make sense\n\n## After the Design\n\n**Documentation:**\n- Write the validated design to `docs/plans/YYYY-MM-DD--design.md`\n- Use elements-of-style:writing-clearly-and-concisely skill if available\n- Commit the design document to git\n\n**Implementation:**\n- Invoke the writing-plans skill to create a detailed implementation plan\n- Do NOT invoke any other skill. writing-plans is the next step.\n\n## Key Principles\n\n- **One question at a time** - Don't overwhelm with multiple questions\n- **Multiple choice preferred** - Easier to answer than open-ended when possible\n- **YAGNI ruthlessly** - Remove unnecessary features from all designs\n- **Explore alternatives** - Always propose 2-3 approaches before settling\n- **Incremental validation** - Present design, get approval before moving on\n- **Be flexible** - Go back and clarify when something doesn't make sense\n \n\n \n Showing up to 200 items (files + folders).\n\n/Users/bob/.gemini/extensions/superpowers/skills/brainstorming/\n└───SKILL.md\n \n"

"content": "I've refined the design for the **Scheduled Daily Check (Lambda)** and will now propose three different approaches for implementing it, focusing on accuracy, cost, and efficiency.\n\n### Proposed Approaches\n\n#### Option 1: Lambda Queries S3 Request Metrics (Recommended)\n* **Mechanism:** Enable **S3 Request Metrics** (CloudWatch) for buckets that opt-in. A Lambda runs once a day and queries the `PutRequests` metric for the previous 24-hour window.\n* **Pros:** Very fast and accurate; no need to iterate through potentially millions of objects in a bucket.\n* **Cons:** S3 Request Metrics have an additional cost (~$0.60 per metric per month).\n\n#### Option 2: Lambda Lists Recent Objects (Limited)\n* **Mechanism:** The Lambda uses `ListObjectsV2` to check for recent activity. Since S3 doesn't support sorting by date, it would list a limited number of objects (e.g., the first 1000) and check their `LastModified` timestamp.\n* **Pros:** No additional AWS managed service costs; simple implementation for small to medium buckets.\n* **Cons:** Unreliable for very large buckets where new files might not appear in the first page of results (lexicographical order); listing millions of objects to find one recent one would be slow and potentially expensive in request costs.\n\n#### Option 3: Custom \"Heartbeat\" Metric via S3 Events\n* **Mechanism:** Configure an S3 Event Notification for `ObjectCreated` to trigger a tiny Lambda that increments a custom CloudWatch metric (e.g., `BucketWriteHeartbeat`). The daily Lambda (or a direct CloudWatch Alarm) checks this metric.\n* **Pros:** Extremely accurate and provides real-time visibility into writes.\n* **Cons:** Adds a Lambda execution for *every* file write, which could be costly for high-volume buckets.\n\n---\n\n**My Recommendation:**\nI recommend **Option 1 (S3 Request Metrics)** because it is the most robust and performant way to check for activity without the complexity and risk of listing objects. While it has a small monthly cost, it is predictable and scales perfectly regardless of bucket size.\n\n---\n\n**Question for clarification:**\nDoes the bucket expect a high volume of writes (thousands per day), or is it relatively low volume? (This helps determine if the S3 Request Metrics cost is justified vs. the S3 Event approach).",

Alerting Flow\nIf the count is 0, the Lambda sends a message to your existing SNS topics:\n* `data.aws_sns_topic.infrastructure_slack_sns_topic`\n* `data.aws_sns_topic.infrastructure_opsgenie_sns_topic`\n\n#### Pros vs. Cons\n* **Pros:** Extremely fast and efficient regardless of bucket size; doesn't require listing millions of objects.\n* **Cons:** S3 Request Metrics cost ~$0.60/month per bucket.\n\n---\n\n**Next Steps for Design:**\nWould you like to see how we'd add the `enable_missing_writes_alert` flag to the `custom_s3_buckets` configuration in `locals.tf`?",

Must fix before completing:\n\n[Show failures]\n\nCannot proceed with merge/PR until tests pass.\n```\n\nStop. Don't proceed to Step 2.\n\n**If tests pass:** Continue to Step 2.\n\n### Step 2: Determine Base Branch\n\n```bash\n# Try common base branches\ngit merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null\n```\n\nOr ask: \"This branch split from main - is that correct?\"\n\n### Step 3: Present Options\n\nPresent exactly these 4 options:\n\n```\nImplementation complete. What would you like to do?\n\n1. Merge back to locally\n2. Push and create a Pull Request\n3. Keep the branch as-is (I'll handle it later)\n4. Discard this work\n\nWhich option?\n```\n\n**Don't add explanation** - keep options concise.\n\n### Step 4: Execute Choice\n\n#### Option 1: Merge Locally\n\n```bash\n# Switch to base branch\ngit checkout \n\n# Pull latest\ngit pull\n\n# Merge feature branch\ngit merge \n\n# Verify tests on merged result\n\n\n# If tests pass\ngit branch -d \n```\n\nThen: Cleanup worktree (Step 5)\n\n#### Option 2: Push and Create PR\n\n```bash\n# Push branch\ngit push -u origin \n\n# Create PR\ngh pr create --title \"\" --body \"$(cat <<'EOF'\n## Summary\n<2-3 bullets of what changed>\n\n## Test Plan\n- [ ] <verification steps>\nEOF\n)\"\n```\n\nThen: Cleanup worktree (Step 5)\n\n#### Option 3: Keep As-Is\n\nReport: \"Keeping branch <name>. Worktree preserved at <path>.\"\n\n**Don't cleanup worktree.**\n\n#### Option 4: Discard\n\n**Confirm first:**\n```\nThis will permanently delete:\n- Branch <name>\n- All commits: <commit-list>\n- Worktree at <path>\n\nType 'discard' to confirm.\n```\n\nWait for exact confirmation.\n\nIf confirmed:\n```bash\ngit checkout <base-branch>\ngit branch -D <feature-branch>\n```\n\nThen: Cleanup worktree (Step 5)\n\n### Step 5: Cleanup Worktree\n\n**For Options 1, 2, 4:**\n\nCheck if in worktree:\n```bash\ngit worktree list | grep $(git branch --show-current)\n```\n\nIf yes:\n```bash\ngit worktree remove <worktree-path>\n```\n\n**For Option 3:** Keep worktree.\n\n## Quick Reference\n\n| Option | Merge | Push | Keep Worktree | Cleanup Branch |\n|--------|-------|------|---------------|----------------|\n| 1. Merge locally | ✓ | - | - | ✓ |\n| 2. Create PR | - | ✓ | ✓ | - |\n| 3. Keep as-is | - | - | ✓ | - |\n| 4. Discard | - | - | - | ✓ (force) |\n\n## Common Mistakes\n\n**Skipping test verification**\n- **Problem:** Merge broken code, create failing PR\n- **Fix:** Always verify tests before offering options\n\n**Open-ended questions**\n- **Problem:** \"What should I do next?\" → ambiguous\n- **Fix:** Present exactly 4 structured options\n\n**Automatic worktree cleanup**\n- **Problem:** Remove worktree when might need it (Option 2, 3)\n- **Fix:** Only cleanup for Options 1 and 4\n\n**No confirmation for discard**\n- **Problem:** Accidentally delete work\n- **Fix:** Require typed \"discard\" confirmation\n\n## Red Flags\n\n**Never:**\n- Proceed with failing tests\n- Merge without verifying tests on result\n- Delete work without confirmation\n- Force-push without explicit request\n\n**Always:**\n- Verify tests before offering options\n- Present exactly 4 options\n- Get typed confirmation for Option 4\n- Clean up worktree for Options 1 & 4 only\n\n## Integration\n\n**Called by:**\n- **subagent-driven-development** (Step 7) - After all tasks complete\n- **executing-plans** (Step 5) - After all batches complete\n\n**Pairs with:**\n- **using-git-worktrees** - Cleans up worktree created by that skill\n </instructions>\n\n <available_resources>\n Showing up to 200 items (files + folders).\n\n/Users/bob/.gemini/extensions/superpowers/skills/finishing-a-development-branch/\n└───SKILL.md\n </available_resources>\n</activated_skill>"
