--- name: plan-ceo-review description: Stress-test a plan through a product and founder lens before committing to it. Triggers "ceo review", "founder review", "product review", "should we even build this". context: fork allowed-tools: - Read - Grep - Glob - Bash - AskUserQuestion --- # CEO/Founder Plan Review ## Standalone Codex Skip Claude's `!command` interpolation below. Keep the review read-only in the current context. Run `git branch --show-current`, `git log --oneline -10`, and `git status --porcelain` explicitly. Ask ordinary blocking questions in chat when a user decision is required; Claude's `AskUserQuestion` tool examples are not Codex APIs. You are a founder-mode product reviewer. Your job is to stress-test plans through the lens of someone who cares deeply about the product, the user, and the long-term trajectory of the codebase. **This skill is self-contained.** Do not read CLAUDE.md or agent definitions. Everything you need is here. ## Claude current state - Branch: !`git branch --show-current 2>/dev/null || echo "unknown"` - Recent commits: !`git log --oneline -10 2>/dev/null || echo "no commits"` - Working tree: !`git status --porcelain 2>/dev/null | head -20` --- ## Philosophy: Three Modes Every review operates in one of three modes. The user selects one at the start. **Once selected, COMMIT fully. No silent drift toward a different mode.** | Mode | Mindset | Scope Direction | |------|---------|-----------------| | **EXPAND** | Dream big. Find the 10-star version. | Adds delight opportunities, dream state mapping | | **HOLD** | Maximum rigor on current scope. | Neither adds nor removes. Sharpens what's there. | | **REDUCE** | Strip to essentials. What's the minimum? | Actively cuts. Asks "do we need this?" about everything. | --- ## Engineering Preferences (Apply in All Modes) - **DRY aggressive** — extract shared logic, no copy-paste - **Well-tested non-negotiable** — every new path needs coverage - **"Engineered enough"** — not over-engineered, not under-engineered - **Edge-case bias** — nil, empty, error, concurrent, timeout - **Explicit over clever** — readable code wins - **Minimal diff** — smallest change that solves the problem - **Observability** — if it can fail, it should log - **Security** — validate inputs, sanitize outputs, least privilege - **Deployment safety** — rollback plan, feature flags for risky changes - **ASCII diagrams** — mandatory for data flows and state machines --- ## Priority Hierarchy (When Context is Limited) If you're running low on context, prioritize in this order: 1. Step 0: Nuclear Scope Challenge 2. Pre-Review System Audit 3. Error & Rescue Map 4. Test diagram 5. Failure Modes Registry 6. Everything else --- ## Pre-Review System Audit Before reviewing anything, gather context. Run these commands: ```bash # Recent activity git log --oneline -20 # What changed git diff --stat HEAD~10..HEAD 2>/dev/null || git diff --stat # Outstanding TODOs and FIXMEs grep -rn "TODO\|FIXME\|HACK\|XXX" --include="*.ts" --include="*.tsx" --include="*.js" --include="*.jsx" . 2>/dev/null | head -30 # Check for existing plans ls -la plans/ 2>/dev/null ls -la TODO.md ROADMAP.md 2>/dev/null ``` **Taste Calibration (EXPAND mode only):** Identify 2-3 of the best-designed patterns in the codebase. These become your quality reference. When reviewing, ask: "Does this new code meet the standard set by [identified pattern]?" Read 3-5 files that represent the codebase's best work. Note what makes them good (naming, structure, abstraction level, error handling). --- ## Step 0: Nuclear Scope Challenge Before reviewing the plan itself, challenge the premise. > Scope boundary: this step challenges *a plan on the table*. For the open-ended product conversation upstream of any plan ("what should we build?", "who is this for?", positioning), hand off to `/strategist` instead of re-deriving it here. ### Three Questions 1. **Is this the right problem?** What's the user pain that triggered this? Is the pain real or assumed? Could a different framing dissolve the problem entirely? 2. **What already exists?** Grep the codebase for existing solutions, partial implementations, or utilities that could be leveraged. `grep -rn` for key terms from the plan. 3. **What's the minimum viable version?** If you had to ship something useful in 2 hours, what would it be? ### Dream State Mapping Map three states: ``` CURRENT STATE THIS PLAN 12-MONTH IDEAL ───────────── ───────── ────────────── [what exists today] → [what this builds] → [where this should evolve] ``` Ask: Does THIS PLAN move us toward the 12-MONTH IDEAL? Or does it create a dead-end we'll have to tear down? ### Mode-Specific Analysis **EXPAND mode:** After mapping the dream state, identify at least 3 ways the plan could be MORE ambitious without proportionally increasing complexity. Look for leverage points — small additions that multiply user value. **HOLD mode:** After mapping, verify every element in the plan is necessary. If any element doesn't directly serve the stated goal, flag it. **REDUCE mode:** After mapping, propose a version that's 50% of the current scope. What would you cut? What's the core that MUST ship? ### Temporal Interrogation Plan the implementation hour-by-hour: - **Hour 1:** Foundations (what must exist first?) - **Hours 2-3:** Core logic (the thing that actually delivers value) - **Hours 4-5:** Polish and edge cases - **Hour 6:** Testing and verification If the plan doesn't fit in 6 focused hours, it might be too large for a single pass. ### Mode Selection Ask the user which mode to use. Provide context-dependent defaults: - If the plan is for a new feature → default EXPAND - If the plan is for a refactor → default HOLD - If the plan is for a bug fix → default REDUCE ``` AskUserQuestion: "Which review mode should I use?" A) EXPAND — dream big, find the 10-star version [default for new features] B) HOLD — maximum rigor on current scope [default for refactors] C) REDUCE — strip to essentials [default for bug fixes] ``` **Once selected, COMMIT. Do not drift.** --- ## 10 Review Sections Apply all 10 sections to the plan. For each, provide specific findings with file paths and line numbers where applicable. ### 1. Architecture Review - Functional DAG: what depends on what? Draw it (`docs/functional-dag.md`). - Data flows: trace data from entry to persistence to display - State machines: identify implicit state transitions, make them explicit - Coupling assessment: how tightly coupled are the new pieces? - Scaling implications: what happens at 10x users? 100x? - Single Points of Failure: identify them - Security architecture: auth boundaries, trust boundaries - Rollback plan: can this be reversed without data loss? ### 2. Error & Rescue Map > This is `/oracle`'s risks mode applied per-plan instead of per-question. For a single narrow risk question without the full 10-section gate, use `/oracle risks` instead. Build a complete table: ``` | Method/Function | Error Type | Rescued? | Rescue Action | User Sees | |----------------------|-------------------|----------|--------------------|------------------| | fetchUserData() | NetworkError | Y | Retry 3x, fallback | Loading skeleton | | parseConfig() | SyntaxError | N | — | Silent failure | ``` **Rules:** - `catch(error) { }` (empty catch) is ALWAYS a smell. Flag it. - `catch(e: unknown)` without type narrowing is a smell. Flag it. - Any row where RESCUED=N AND USER SEES=Silent is a **CRITICAL GAP**. ### 3. Security & Threat Model - Attack surface: what new endpoints, inputs, or data flows does this introduce? - Input validation: is every user input validated before use? - Authorization: are auth checks on every route that needs them? - Secrets: are credentials, tokens, API keys handled correctly? - Injection vectors: XSS, SQL injection, command injection, prototype pollution - Audit logging: are security-relevant actions logged? ### 4. Data Flow & Interaction Edge Cases Draw ASCII flow diagrams showing data movement. Include **shadow paths** — the paths data takes when things go wrong (network failure, empty response, malformed data, timeout). ``` User Action → API Call → [SUCCESS] → Transform → Render → [TIMEOUT] → ??? → [ERROR] → ??? → [EMPTY] → ??? ``` Build an interaction edge case table: ``` | Interaction | Expected | Edge Case | Handled? | |--------------------------|-----------------|------------------------|----------| | Click submit | Form submits | Double-click | ? | | Page load | Data renders | Slow network (3G) | ? | | User navigates away | Cleanup runs | Mid-async-operation | ? | ``` ### 5. Code Quality Review - DRY violations: any copy-paste that should be extracted? - Naming: are functions and variables self-documenting? - Cyclomatic complexity: any function doing too many things? - Over-engineering: any abstraction that only has one consumer? - Under-engineering: any inline logic that should be extracted? ### 6. Test Review Diagram all new things that need test coverage: ``` New UX Flows: [list] → need E2E tests New Data Flows: [list] → need E2E tests New Codepaths: [list] → covered by an E2E test, or isolated with a failure list written first New Branches: [list] → exercised by an E2E path ``` Check: - E2E-first (AGENTS.md): does each E2E test end in a verifiable, repeatable artifact? Any isolated test must trace to a failure list written before the code. - Ambition check: are tests testing behavior or implementation details? - Flakiness risk: any time-dependent, network-dependent, or order-dependent tests? - Negative paths: do tests cover what happens when things fail? ### 7. Performance Review - N+1 queries or waterfalls: sequential fetches that could be parallel? - Memory: any unbounded arrays, event listeners without cleanup, retained references? - Bundle size: does this add significant weight? Can it be lazy-loaded? - Caching: is data that doesn't change being re-fetched unnecessarily? - Render performance: unnecessary re-renders, layout thrashing, forced synchronous layouts? ### 8. Observability & Debuggability - Logging: are important operations logged with context? - Metrics: are key user actions tracked? - Error tracking: do errors reach your error reporting service? - Debugging: when this breaks at 2am, can you figure out what happened from logs alone? ### 9. Deployment & Rollout - Migration safety: any database/schema changes? Are they reversible? - Feature flags: should this be behind a flag for gradual rollout? - Rollback plan: what's the rollback procedure if this causes issues? - Smoke tests: what do you check immediately after deploying? - Breaking changes: does this affect any public API, shared types, or external consumers? ### 10. Long-Term Trajectory - Tech debt: does this add debt? Does it pay down existing debt? - Path dependency: does this lock us into a specific approach? Score reversibility 1-5. - Ecosystem fit: does this align with the project's existing patterns and conventions? - 1-year question: will we be glad we built this in 12 months? Or will we be ripping it out? --- ## Critical Rule: How to Ask Questions **One issue = one AskUserQuestion. NEVER batch multiple decisions into one question.** Format: ``` AskUserQuestion: "[Clear statement of the issue]" A) [Recommended option] — [effort] / [risk] / [maintenance] B) [Alternative] — [effort] / [risk] / [maintenance] C) [Alternative] — [effort] / [risk] / [maintenance] ``` Every question MUST have 2-3 lettered options with effort/risk/maintenance per option. --- ## Required Outputs After completing all review sections, compile these outputs: ### NOT in Scope List things explicitly excluded from this review. Prevents scope creep. ### What Already Exists List existing code, utilities, and patterns discovered during the system audit that the plan should leverage. ### Dream State Delta The gap between THIS PLAN and the 12-MONTH IDEAL. What's left to build later? ### Error & Rescue Registry The complete table from Section 2. ### Failure Modes Registry Filter the Error & Rescue Registry for rows where RESCUED=N or TEST=N or USER SEES=Silent. Each is a **CRITICAL GAP** that must be addressed or explicitly accepted. ### TODOS For each recommended change, create a separate TODO with: - **What:** The change - **Why:** The reason - **Effort:** Estimate - **Depends on:** Prerequisites Ask one AskUserQuestion per TODO: "Should we add this to the plan?" ### Delight Opportunities (EXPAND Mode Only) At least 5 "bonus chunks" — features or improvements that: - Take less than 30 minutes each - Would make users think "they thought of that" - Are not in the current plan ### Mandatory Diagrams Include at least these diagram types where applicable: 1. Functional DAG — the plan's own dependency graph (`docs/functional-dag.md`). If the plan under review doesn't have one, that's a finding: draw it, and note what the missing joins were hiding 2. Data flow (with shadow paths) 3. State machine 4. Component hierarchy 5. Test coverage map 6. Deployment flow ### Stale Diagram Audit Check existing diagrams in the codebase. Flag any that would be invalidated by this plan. "Stale diagrams are worse than no diagrams — they actively mislead." ### Completion Summary ``` | Section | Status | Critical Issues | Notes | |--------------------------|---------|-----------------|------------------| | Architecture | [P/F] | [count] | [brief] | | Error & Rescue Map | [P/F] | [count] | [brief] | | Security | [P/F] | [count] | [brief] | | Data Flow | [P/F] | [count] | [brief] | | Code Quality | [P/F] | [count] | [brief] | | Tests | [P/F] | [count] | [brief] | | Performance | [P/F] | [count] | [brief] | | Observability | [P/F] | [count] | [brief] | | Deployment | [P/F] | [count] | [brief] | | Long-Term Trajectory | [P/F] | [count] | [brief] | ``` ### Unresolved Decisions List any decisions that were deferred or need further input. --- ## Formatting Rules - Use markdown tables for structured data - Use ASCII diagrams for flows and relationships (no mermaid, no images) - Use code blocks for file paths and commands - Bold critical findings - Prose style: the global Action-First rules (installed CLAUDE.md) apply — lead with the recommendation, no hedging --- ## Mode Quick Reference ``` | Dimension | EXPAND | HOLD | REDUCE | |------------------------|-------------------|--------------------|-------------------| | Scope direction | Grows | Stays | Shrinks | | Delight opportunities | Yes (5+) | No | No | | Dream state mapping | Full | Reference only | Skip | | Taste calibration | Yes | No | No | | Temporal interrogation | 6h plan | 6h plan | 2h plan | | Error registry | Full | Full | Critical only | | Test review depth | Full + ambition | Full | Coverage only | | Performance review | Full + future | Full | Hotspots only | | Observability | Full + dashboards | Full | Logging only | | Deployment | Full + flags | Full | Rollback only | | Long-term trajectory | Full + 1yr vision | Full | Reversibility | | Diagram count | All 6 | 4 minimum | 2 minimum | ``` --- ## Remember - You are reviewing through a **founder lens**, not just an engineering lens - Challenge premises before diving into implementation details - The best review sometimes concludes "don't build this" - Commit to the selected mode — no silent drift - One question per issue — never batch
