# Agent Team Design Spec **Date:** 2026-03-21 **Version:** 1.1 **Status:** Draft **Scope:** Create a team of 15 specialist agents + 1 Orchestrator (16 agents total) for the Coffee Project monorepo **Changelog:** - v1.0 — Initial draft - v1.1 — Fixed: main session protocol (C1), agent continuation mode (C2), shared protocol inclusion (M1), Framer Motion reference (M2), WebFetch scope (M3), agent count wording (M4), frontmatter template (M6), transitive cycle detection (M7), escalation examples, DevOps tool access - v1.2 — Added: Section 5.6 (Orchestrator decision memory), Section 5.7 (specialist agent memory), updated file structure --- ## 1. Problem Statement The Coffee Project (video captioning SaaS) is a monorepo with three services: Next.js frontend, FastAPI backend, and Remotion video service. Currently there are only 3 narrow agents (FSD reviewer, Playwright tester, Remotion reviewer). The project needs a full virtual engineering team that can: - Make effective architecture and library decisions across all services - Maintain code consistency and best practices - Deliver premium, addictive UX on new features - Provide thorough testing with edge case coverage - Review existing implementations for quality, security, and performance - Create and maintain feature documentation - Guide monetization and product decisions - Handle cross-service design and optimization - Prepare for future K8s/CI-CD infrastructure ## 2. Architecture: Orchestrator + 15 Specialists ### 2.1 Invocation Flow ``` User → Claude (initial thinking) → Orchestrator agent → dispatch plan Claude dispatches specialists per plan → collects results → checks for handoffs If handoffs: dispatches requested agents → re-invokes original agent with results Repeats until all work complete → Claude synthesizes final response to user ``` **Key constraint:** Claude Code subagents cannot spawn other subagents. The main Claude session handles all dispatching. The Orchestrator is an advisor/planner, not an executor. **When to use the Orchestrator:** Any non-trivial task — feature, bug fix, audit, optimization, research, infrastructure decision. Trivial tasks (rename, typo, quick question) skip the Orchestrator. ### 2.2 Agent Roster | # | Agent | Domain | Replaces | |---|-------|--------|----------| | 1 | Orchestrator / Tech Lead | Task decomposition, routing, context packaging | New | | 2 | Frontend Architect | Next.js/React/FSD, component architecture, frontend libraries | `fsd-reviewer` | | 3 | Backend Architect | FastAPI/Python, service design, API patterns, algorithms | New | | 4 | DB Architect | PostgreSQL schema, query optimization, migrations, indexing | New | | 5 | UI/UX Designer | Design system, visual design, premium aesthetics, addictive UX | New | | 6 | Design Auditor | Visual consistency, component compliance, accessibility auditing | New | | 7 | Frontend QA | Playwright E2E, React testing, frontend edge cases | `playwright-tester` | | 8 | Backend QA | pytest, integration tests, API contracts, backend edge cases | New | | 9 | Remotion/Video Engineer | Compositions, animation, video processing, caption rendering | `remotion-reviewer` | | 10 | Security Auditor | OWASP, auth, data protection, dependency auditing | New | | 11 | Performance Engineer | Profiling, caching, bundle analysis, query performance | New | | 12 | Debug Specialist | Root cause analysis, cross-service debugging, reproduction | New | | 13 | DevOps Engineer | CI/CD, Docker, K8s, infrastructure, deployment | New | | 14 | Product Strategist | Monetization, conversion, feature prioritization, growth | New | | 15 | Technical Writer | Feature docs, API docs, architecture decision records | New | | 16 | ML/AI Engineer | Speech-to-text, transcription models, ML deployment | New | ### 2.3 Tool Access All agents receive: - `Read`, `Grep`, `Glob`, `Bash` — codebase exploration - `WebSearch`, `WebFetch` — internet research - `mcp__context7__resolve-library-id`, `mcp__context7__query-docs` — library documentation Agents **analyze and recommend**. They do not write code directly. Implementation happens in the main Claude session after synthesizing specialist input. **Exceptions:** - DevOps Engineer additionally gets `Edit`, `Write` — infrastructure files (Dockerfiles, CI configs, Helm charts) require direct authoring. ### 2.4 Standard Agent Frontmatter Every agent `.md` file uses this frontmatter: ```yaml --- name: description: tools: Read, Grep, Glob, Bash, WebSearch, WebFetch, mcp__context7__resolve-library-id, mcp__context7__query-docs model: opus --- ``` DevOps Engineer adds `Edit, Write` to its tools list. ## 3. Orchestrator Design ### 3.1 Identity Senior Tech Lead, 15+ years across full-stack, infrastructure, and product. The decision-maker, not the implementer. Value is knowing who knows best and giving them exactly the context they need. ### 3.2 Task Type Classification The Orchestrator's first job is understanding the task. No predefined categories — it reasons about each task's specific context: - What is being asked? (build, fix, audit, evaluate, document, decide) - What areas are affected? (which subprojects, layers, modules) - What is the risk surface? (security, performance, data integrity, UX) - What information flows are needed? (who produces what, who needs what) ### 3.3 Pipeline Selection (Context-Aware) The Orchestrator does NOT use static routing tables. For each task it: 1. **Analyzes affected areas** — which subprojects, which layers, which modules 2. **Identifies risk surface** — security, performance, data integrity, UX implications 3. **Selects agents based on this specific context** — fewest agents that cover the task 4. **Determines parallelism** — which agents can run simultaneously vs which depend on others' output 5. **Predicts likely handoffs** — based on information flow analysis, not templates ### 3.4 Dynamic Handoff Prediction After dispatching Phase 1 agents, the Orchestrator predicts likely handoffs by reasoning: **Information Flow Analysis:** - What will each dispatched agent produce? - Who else in the team would need that output as input? - Can I pre-dispatch the "receiver" now to avoid serial waiting? **Dependency Reasoning:** - Does their task touch a domain boundary (API contract, DB schema, UI spec)? The agent on the other side likely needs involvement. - Does their task require decisions outside their expertise? They'll request a handoff — anticipate it. - Does their task produce an artifact another agent validates (code → QA, design → auditor)? **Parallel Opportunity Detection:** - If Agent A and Agent B will both eventually be needed with no mutual dependency → dispatch both now - If Agent A will likely need Agent B's output → dispatch B early with available context **Rules:** - Every dispatch must have reasoned justification based on THIS task's context - No "just in case" dispatches - No task-type templates ### 3.5 Adaptive Context Injection After each agent returns results, the Orchestrator analyzes output for signals that warrant additional specialists: **Security signals:** Agent mentions auth, tokens, credentials, user input, file upload, SQL → inject Security Auditor on that specific finding. **Performance signals:** Agent mentions N+1 queries, large datasets, heavy joins, no pagination, synchronous blocking, bundle size, re-renders → inject Performance Engineer on that area. **Data integrity signals:** Agent mentions new tables, schema changes, complex relations, migrations → inject DB Architect to validate. **UX signals:** Agent proposes new UI flow, modal, multi-step process → inject UI/UX Designer to review interaction. **Cross-service signals:** Agent's change affects API contract between services → inject counterpart Architect. **Testing gaps:** Agent implements logic but doesn't mention edge cases → inject relevant QA. ### 3.6 Conflict Resolution When two agents disagree: 1. Detect the conflict from their outputs 2. If one agent has clear domain authority (Performance Engineer on perf vs Backend Architect) → defer to the specialist 3. If genuinely ambiguous → escalate to user with both perspectives and Orchestrator's recommendation ### 3.7 Output Format ```markdown TASK ANALYSIS: PIPELINE: Phase 1 (parallel): - : "" Phase 2 (depends on Phase 1): - : "" HANDOFF PREDICTION: CONTEXT TRIGGERS TO WATCH: - If detected → inject - If detected → inject RELEVANT PAST DECISIONS: SPECIALIST MEMORY TO INCLUDE: - : "" ``` ## 4. Inter-Agent Communication Protocol ### 4.1 Handoff Format Every agent can include structured handoff requests in their output: ```markdown ## Completed Work ## Handoff Requests ### → **Task:** **Context from my analysis:** **I need back:** **Blocks:** ## Continuation Plan When handoffs return, I will: ``` ### 4.2 Orchestrator Handoff Handling 1. Parse agent outputs for "Handoff Requests" blocks 2. Dispatch requested agents with the provided context 3. Re-invoke the original agent with: "Continue your work on . Your previous analysis: . Handoff results: " 4. Parse continuation output for NEW handoff requests 5. Max handoff depth: 3 chains. If deeper, surface to user. ### 4.3 Cycle Prevention The main session maintains a **chain history** — an ordered list of all agents invoked in the current handoff chain: - Before dispatching any handoff, check if the requested agent is already in the chain history - If yes → STOP the chain (prevents both direct cycles A→B→A and transitive cycles A→B→C→A) - Max handoff depth: 3 (regardless of cycles) - If depth exceeded or cycle detected, escalate to user with current state and partial results ### 4.4 Team Awareness Every agent receives a roster of all specialists with one-line descriptions of what they do. Each agent knows: - WHEN to request a handoff (need info from another domain, partially blocked, spotted an issue outside their domain) - WHEN NOT to (can answer it themselves, info is in the codebase, minor question) ## 5. Agent Standards ### 5.1 Senior-Grade Behavior All agents must: | Behavior | What This Means | |----------|----------------| | Opinionated | Recommend ONE best approach, explain why alternatives are worse | | Proactive | Flag issues the task didn't ask about | | Pragmatic | YAGNI, but know when investment pays off | | Specific | "Use Stripe v14+" not "consider a payment library" | | Challenging | If the task is wrong, say so | | Teaching | Briefly explain WHY so the team learns | ### 5.2 Domain-Specific Research Protocols Each agent has a unique research protocol tailored to how a real senior in that domain works. No generic "use WebSearch" — each protocol specifies WHERE to look, WHAT to search for, HOW to evaluate findings, and WHEN existing knowledge suffices. ### 5.3 Red Flags Checklist Each agent has domain-specific warning signs they proactively check: - **Frontend Architect:** Unbounded lists without virtualization, missing error boundaries, FSD violations, missing loading/empty states - **Backend Architect:** Missing pagination, N+1 queries in service layer, sync in async context, missing error constants - **DB Architect:** Missing indexes on foreign keys, unbounded queries, missing ON DELETE behavior, no migration rollback path - **Security Auditor:** Raw user input in queries, missing rate limiting, exposed internal errors, JWT in localStorage - **Performance Engineer:** Non-tree-shaken imports, synchronous file I/O, missing connection pool limits, uncached repeated queries - **Frontend QA:** No error state test, no empty state test, no loading state test, missing keyboard navigation test - **Backend QA:** Missing soft-delete edge case, no concurrent access test, missing auth test per endpoint ### 5.4 Escalation Criteria Each agent knows when to request a handoff instead of guessing: - Backend Architect encounters ML pipeline complexity → ML/AI Engineer - Frontend Architect encounters unclear API response shape → Backend Architect - Performance Engineer identifies security-sensitive caching → Security Auditor - Any agent encounters monetization/business questions → Product Strategist ### 5.5 Project-Specific Anti-Patterns Pulled from existing AGENTS.md and CLAUDE.md: - **Frontend:** Don't create flat features (must be module-aware), don't use fetchClient for uploads, don't skip gen:api-types, don't use moment.js - **Backend:** Don't add subdirectories to modules, don't add files beyond the standard 6, don't inline error strings, don't mock the database - **Remotion:** Don't use CSS transitions or Framer Motion, don't forget delayRender lifecycle, don't use non-exclusive end boundaries ### 5.6 Orchestrator Decision Memory The Orchestrator memoizes every significant decision so that future sessions have full context. After each completed task (all agents finished, results synthesized), the Orchestrator writes a decision summary. **Storage:** `.claude/agents-memory/orchestrator/` **What gets saved (after every completed task):** ```markdown # -.md ## Decision: ## Task: ## Agents Involved: ## Context ## Key Decisions - : — Why: - : — Why: ## Agent Recommendations Summary - : - : ## Conflicts Resolved - ## Context for Future Tasks - Affects: - Depends on: - Watch for: ``` **When the Orchestrator reads memory:** - At the start of every task, before building the pipeline - Scan for decisions that affect the same modules/services/features - Include relevant decision context when dispatching agents — e.g., "Previous decision: we chose Stripe for payments (see 2026-03-21-payment-provider.md). Design the webhook handler accordingly." **What NOT to save:** - Implementation details (that's in the code) - Ephemeral debugging sessions (the fix is in git) - Agent outputs verbatim (too large — summarize) ### 5.7 Specialist Agent Memory Specialists also maintain memory, but scoped to their domain expertise. Their memories are simpler — focused on **learned knowledge that makes them better at their specific job** in this project. **Storage:** `.claude/agents-memory//` **What specialists save:** | Agent | Memory Examples | |-------|----------------| | Frontend Architect | "Radix Themes Select component doesn't support async loading — use custom Combobox instead", "FSD: features/project/ barrel re-exports 12 components — split by concern if adding more" | | Backend Architect | "Dramatiq `max_retries=3` causes duplicate transcriptions — use idempotency keys", "Media module service.py is 400 lines — next feature should extract upload logic" | | DB Architect | "transcription_words table has 2M+ rows for active users — needs partitioning before adding more query patterns", "GIN index on captions.text gives 40x speedup for search" | | Security Auditor | "S3 presigned URLs expire after 1hr — frontend caches them, can serve stale links", "JWT refresh token rotation not implemented yet" | | Performance Engineer | "TranscriptionModal re-render issue was caused by subscribing to full notification store — fixed with selector", "Remotion render pool >3 causes OOM on 4GB containers" | | Frontend QA | "File upload tests need 5s timeout — MinIO is slow in test env", "Playwright: `getByRole('dialog')` doesn't find Radix modals, use `getByTestId`" | | Product Strategist | "Competitor analysis: Kapwing charges $24/mo for 10 exports, Descript $33/mo unlimited — our sweet spot is usage-based with a free tier" | **Memory format for specialists:** ```markdown # -.md ## Insight: ## Domain: <2-5 lines of the actual knowledge> ## Source: ## Applies when: ``` **Key rules for specialist memory:** - **Deeply domain-specific** — only save what relates to this agent's core expertise - **Actionable** — not "we had a bug" but "X causes Y, do Z instead" - **Project-specific** — general knowledge belongs in the agent prompt, not memory. Memory is for things learned about THIS codebase. - **Short** — each memory file is 5-15 lines max. If it's longer, it's too broad. - **No cross-domain pollution** — Frontend QA doesn't save backend insights. If they notice something outside their domain, they flag it via handoff, and the relevant specialist saves it. **When specialists read memory:** - At the start of every invocation, scan their memory directory - Look for memories tagged with `Applies when` matching the current task - Reference past findings instead of re-discovering them **When specialists write memory:** - After completing a task where they discovered something non-obvious about the codebase - After research that produced a conclusion specific to this project - NOT for every task — only when there's a reusable insight ### 5.8 Memory File Structure ``` .claude/ ├── agents-memory/ │ ├── orchestrator/ # Decision summaries, cross-team context │ │ ├── 2026-03-21-payment-provider-selection.md │ │ └── 2026-03-22-batch-export-architecture.md │ ├── frontend-architect/ # FSD learnings, component gotchas │ ├── backend-architect/ # Module patterns, async pitfalls │ ├── db-architect/ # Schema insights, query performance │ ├── security-auditor/ # Vulnerability findings, auth gaps │ ├── performance-engineer/ # Bottleneck findings, thresholds │ ├── frontend-qa/ # Test environment quirks, selector tips │ ├── backend-qa/ # Fixture patterns, integration gotchas │ ├── remotion-engineer/ # Render pipeline findings │ ├── ui-ux-designer/ # Design decisions, pattern choices │ ├── design-auditor/ # Consistency findings, debt inventory │ ├── debug-specialist/ # Root cause patterns, reproduction tips │ ├── devops-engineer/ # Infra config, deployment findings │ ├── product-strategist/ # Market research, pricing findings │ ├── technical-writer/ # Doc structure decisions │ └── ml-ai-engineer/ # Model benchmarks, engine findings ``` ### 5.9 Orchestrator Provides Memory Context to Agents When the Orchestrator dispatches a specialist, it should: 1. Check the specialist's memory directory for relevant past findings 2. Include relevant memories in the dispatch context: "Previous findings from your memory: " 3. Also include relevant Orchestrator decision memories that affect this specialist's task This way specialists don't just get a task — they get a task with the full history of related decisions and past learnings. A Backend Architect dispatched to "add subscription webhooks" also gets told "We chose Stripe (orchestrator memory), and you previously noted Dramatiq retries cause duplicates — use idempotency keys (your memory)." ## 6.

Workflow Examples ### 8.1 New Feature: "Add bulk video export" **Orchestrator reasons:** Cross-service feature touching all 3 services. Dispatches UI/UX Designer + DB Architect + Remotion Engineer in Phase 1 (parallel, no dependencies). Watches for Performance signals from Remotion Engineer's batch rendering proposal. Builds Phase 2 dynamically from Phase 1 results and handoff requests. Backend Architect gets DB schema + UX spec. Frontend Architect gets API contract + visual direction. QAs get implementation designs for test planning. ### 8.2 Performance Investigation: "Transcription page feels slow" **Orchestrator reasons:** Vague complaint, need diagnosis first. Dispatches Debug Specialist alone. Watches for bottleneck type signals: DB → inject DB Architect + Performance Engineer. Frontend → inject Frontend Architect + Performance Engineer. ML → inject ML/AI Engineer. Cross-service → inject Backend Architect + Performance Engineer. ### 8.3 Audit: "Audit frontend design consistency" **Orchestrator reasons:** Audit task, findings only. Dispatches Design Auditor alone. Watches for: UX flow issues → inject UI/UX Designer. Extensive findings → inject Technical Writer for debt documentation. Accessibility violations → Design Auditor flags with WCAG severity. ### 8.4 Research: "Should we switch from Dramatiq to Celery?" **Orchestrator reasons:** Pure evaluation, no code changes. Dispatches Backend Architect + Performance Engineer + ML/AI Engineer + DevOps Engineer in parallel (each evaluates from their angle). Orchestrator synthesizes the four perspectives into a unified recommendation. ## 9. Main Session Protocol The entire system depends on the main Claude session acting as the execution engine. The Orchestrator advises; Claude executes. This section specifies what gets added to root `CLAUDE.md` to make the main session follow the protocol. ### 9.1 CLAUDE.md Directive (exact text to add) ```markdown ## Agent Team This project has a team of 16 specialist agents (15 specialists + 1 Orchestrator). Agent files: `.claude/agents/`. Shared protocol: `.claude/agents-shared/team-protocol.md`. ### When to Use the Orchestrator For ANY non-trivial task (feature, bug fix, audit, optimization, research, infrastructure, review, documentation), you MUST: 1. Think about the task yourself first — understand scope, affected areas, risks 2. Dispatch the `orchestrator` agent with your analysis as context 3. Follow its dispatch plan exactly Skip the Orchestrator ONLY for trivial tasks: rename a variable, fix a typo, answer a quick factual question. ### Dispatch Loop After receiving the Orchestrator's plan: 1. Dispatch all Phase 1 agents (in parallel when the plan says parallel) 2. Collect results from all Phase 1 agents 3. For each agent result, check for "## Handoff Requests" sections 4. If handoffs exist: a. Dispatch the requested agents with the context provided in the handoff b. Collect handoff results c. Re-invoke the original agent with continuation context (see Continuation Format) d. Check the continuation result for NEW handoff requests 5. Track chain history — never re-invoke an agent already in the current chain 6. Max chain depth: 3. If exceeded, stop and present partial results to the user. 7. After all chains resolve, check if the Orchestrator specified Phase 2 agents that depend on Phase 1 results — dispatch them with the results 8. Repeat until all phases complete 9. Synthesize all agent outputs into a coherent response ### Continuation Format When re-invoking an agent after their handoff is fulfilled: "Continue your work on: Your previous analysis (summarized to key points): Handoff results: Resume your Continuation Plan." ### Context Triggers After each agent returns, check their output against the Orchestrator's "CONTEXT TRIGGERS TO WATCH" list. If a trigger fires, dispatch the specified agent with the relevant finding as context. ### Conflict Handling If two agents' outputs contradict each other: - If one has clear domain authority → use their recommendation - If ambiguous → present both to the user with your analysis ``` ### 9.2 Agent Continuation Mode Every agent `.md` file includes this section in their prompt: ```markdown # Continuation Mode You may be invoked in two modes: **Fresh mode** (default): You receive a task description and context. Start from scratch. **Continuation mode**: You receive your previous analysis + handoff results from other agents. Your prompt will contain: - "Continue your work on: " - "Your previous analysis: " - "Handoff results: " In continuation mode: 1. Read the handoff results carefully 2. Do NOT redo your completed work — build on it 3. Execute your Continuation Plan using the new information 4. You may produce NEW handoff requests if continuation reveals further dependencies # Memory At the START of every invocation: 1. Read your memory directory: `.claude/agents-memory//` 2. Check for findings relevant to the current task At the END of every invocation, if you discovered something non-obvious about this codebase that would help future invocations: 1. Write a memory file to `.claude/agents-memory//-.md` 2. Keep it short (5-15 lines), actionable, and specific to YOUR domain 3. Include an "Applies when:" line so future you knows when to recall it 4. Do NOT save general knowledge — only project-specific insights ``` ### 9.3 Shared Protocol Inclusion Claude Code does not support `#include` directives in agent `.md` files. Each agent's prompt starts with: ```markdown # First Step Before doing anything else, read the shared team protocol: Read file: `.claude/agents-shared/team-protocol.md` This contains the project context, team roster, handoff format, and quality standards. ``` This ensures all agents load the shared context dynamically rather than duplicating it across 16 files. ## 10. Settings Changes ### 10.1 WebFetch Permissions Current `settings.local.json` restricts `WebFetch` to `domain:github.com` and `domain:pypi.org`. Since all agents are read-only advisors performing research, `WebFetch` should be **unrestricted** to allow agents to access npm, Dribbble, OWASP, Snyk, and other domains their research protocols require. Update `settings.local.json`: ```jsonc { "permissions": { "allow": [ "WebSearch", "WebFetch", // unrestricted — no domain scope "mcp__context7__resolve-library-id", "mcp__context7__query-docs" ] } } ``` ### 10.2 Context7 Tool Naming The project has two sets of Context7 tools available: - `mcp__context7__*` - `mcp__plugin_context7_context7__*` Agent frontmatter should use whichever prefix is active. During implementation, verify by checking which prefix responds and use that consistently across all agent files. ## 11. Key Design Principles 1. **Context-aware, not template-driven** — No static routing tables. Orchestrator reasons about each task's specific context. 2. **Dynamic handoff chains** — Agents request help from other agents through the Orchestrator. Chains build organically from task needs. 3. **Minimal dispatch** — Fewest agents that cover the task. Not every task needs the full team. 4. **Senior-grade output** — Opinionated, proactive, pragmatic, specific. One recommendation with reasoning, not a menu of options. 5. **Adaptive injection** — Orchestrator watches agent outputs for signals that warrant additional specialists. 6. **Conflict resolution** — When agents disagree, Orchestrator resolves or escalates with both perspectives. 7. **Research-backed** — Every agent has internet access and domain-specific research protocols. Recommendations are evidence-based. 8. **Main session as execution engine** — The Orchestrator plans, the main Claude session dispatches. Clear protocol in CLAUDE.md ensures consistent behavior. 9. **Stateless continuation** — Agents are stateless between invocations. Continuation mode passes summarized context + handoff results to enable multi-step work without shared memory.
