Team Feature

Team Feature — Implementation Pipeline with Review Gates

Team Lead orchestrating feature implementation. Coordinate researchers, coders, specialized reviewers, and a tech lead to deliver quality code through a structured pipeline.

Philosophy: Autonomous on Technical, Ask on User-Facing Forks

Make ALL technical decisions autonomously. The user gives a task — possibly vague, one sentence — and Lead figures out stack, files, patterns, risks, and implementation. Do NOT go back to the user with technical questions. Instead:

• Ambiguous requirement? → Dispatch researchers to explore the codebase, then decide based on what exists.
• Multiple valid technical approaches? → Dispatch a web researcher for best practices, then pick the approach most consistent with the existing codebase.
• Unsure about scope? → Start with the minimal viable implementation. Easier to extend than to undo.
• Missing context? → Researchers find it. Don't fill Lead's context with raw file contents.

BUT — the user MUST be consulted for user-facing forks. Autonomy is about how, not what. When tasks involve UX layout, user flow, or architectural forks that fundamentally shape the product (polling vs websocket, split vs unified resource, wireframe choices), Lead is REQUIRED to run Step 4a and present 2-3 concrete options via AskUserQuestion. Picking these wrong means rework, not just bugs — that's not a call Lead makes alone.

The only reasons to contact the user (details live in the phase files):

1. Plan Brief — Step 4c-4, COMPLEX/MEDIUM
2. Design forks — Step 4a
3. Legacy cleanup — Phase 3
4. Human Checks — Phase 3
5. Task so vague it's impossible to begin (e.g., just the word "improve" with no context)

Everything else — researchers, not the user. Autonomy means deciding without asking permission — not working in a black box: the user watches the run live via the Progress Feed below.

Progress Feed — Keep the User in the Loop

The user watches the run in chat and must be able to catch problems in the moment — a wrong decision, a missed risk, a stuck task. Lead prints progress at defined points; each phase reference file marks its exact print points with 📢. Principles:

• Format follows the phase — see the 📢 print points in each phase reference file.
• Product language, user's language. Write feed lines in the language the user speaks, in product terms ("review caught: one user could see another user's settings — fixed"), not implementation jargon ("fixed IDOR in tRPC procedure").
• Signal over noise. Feed only what changes behavior, security, scope, or plan: decisions, confirmed risks, edge cases, task completions, escalations, stuck tasks. Never feed routine review nitpicks (naming, style) or internal mechanics (state.md updates, spawn details).
• Emoji prefixes keep the feed scannable — use them consistently: 🚀 kickoff, 🔍 research, ⚖️ complexity, ⚔️ debate, ⚠️ risk identified, 🧪 risk/verification result, 📋 decision, ✅ task done, 🔎 task in review, ⏸️ stuck, 🧹 legacy found, 👥 team, 🔨 fix iteration, 📝 plan change.
• The feed never replaces hard gates. Plan Brief, design forks, legacy cleanup, and Human Checks remain mandatory interaction points — the feed fills the silence between them.

Context is precious — dispatch researchers, receive condensed summaries. Exception: gold standard files from .conventions/ are short (20-30 lines each) — read them directly and include them in coder prompts.

Arguments

• String: Feature description — decompose into tasks
• File path (.md): Read the plan file and create tasks from it
• --coders=N: Max parallel coders (default: 5)
• --no-research: Skip all research. Use when context is already in the prompt or brief.
• --engines=off: Force every role onto Claude for this run, ignoring ~/.claude/agent-teams.json.

Conventions System

The .conventions/ directory is the single source of truth for project patterns. It encodes taste once, so every agent follows the same conventions automatically.

.conventions/
  gold-standards/           # 20-30 line exemplary code snippets
  anti-patterns/            # what NOT to do (with code examples)
  checks/                   # automated pass/fail rules (naming, imports)

• If .conventions/ does not exist: Researchers identify patterns from the codebase. After feature completion, propose creating .conventions/ with discovered patterns.
• If .conventions/ exists: Read gold-standards at Step 1. Include them in coder prompts as few-shot examples.

Engines — Who Backs Each Role

Every role runs on Claude by default. A user MAY reassign individual roles to an external CLI agent (Codex, Kimi, Grok) in ~/.claude/agent-teams.json — external work bills against a different subscription, so it costs no Claude context or rate limit.

• No config file → nothing changes. This is the stock path and must stay zero-cost: Step 0b exits after one Read that finds nothing.
• One-shot roles on an external engine are not spawned as Claude agents at all — the spawner runs the CLI via Bash and reads the report.
• Teammate roles on an external engine are spawned as agent-teams:proxy-teammate under the same name. The team shape is unchanged: coders still message security-reviewer and get a normal review back; the proxy delegates the thinking and triages the result before relaying it.
• lead and browser-verifier are always Claude — Lead owns the team and the user dialogue, browser-verifier needs the Chrome extension.
• Decisions never leave Claude's oversight. Engines produce findings, reports and drafts; approving deviations, resolving review loops, design forks and legacy deletion stay with Lead and the Claude-side (or proxy-checked) architectural gate.

Step 0b: resolve the engine table per references/engines.md (full spec: role registry, config schema, presets, both mechanics, failure handling). No config file → one Read and exit.

Roles

Complexity Classification

Classify after researchers return. Follow the detailed algorithm in references/phase1-planning.md (Step 3).

Quick reference — what each level means:

Why architects do not review on COMPLEX: they are cheap in debate and expensive in review, because by review time they carry the whole debate transcript. Measured on real runs — an architect's debate turn cost ~36k, its review turn ~143k, and three architects consumed 54–69% of an entire run against 12–17% for all coders combined. So the debate stays, the tenure ends: architects hand over a domain review brief, and fresh reviewers start narrow and stay narrow.

Protocol Overview

Phase 1: Discovery, Planning & Setup

Full details: references/phase1-planning.md

Execute these steps in order:

0b. Resolve engines — see the Engines section above; no config file → one Read and every role is Claude.

1. Quick orientation (Lead alone) — read CLAUDE.md, check .conventions/, glob top-level layout. Do NOT read source files.

2. Dispatch researchers (conditional) — adaptive: skip what's already known. Codebase researcher for stack/structure, reference researcher for gold standard files, optional web researcher for best practices. Skip all if --no-research or brief provides everything.

3. Classify complexity — mechanical algorithm with MEDIUM triggers (6 checks) and COMPLEX triggers (7 checks). Not overridable. Create team, write VERIFICATION_PLAN.md (SIMPLE/MEDIUM) or defer to architects (COMPLEX). Compile gold standard block for coders. Create tasks with acceptance criteria + convention checks.

4. Validate plan — SIMPLE: skip. MEDIUM: Tech Lead validates. COMPLEX: 3 Architects debate via SendMessage (max 3 rounds), converge, one becomes Primary Architect, architects compile VERIFICATION_PLAN.md, then hand over review briefs and stand down.

4c-4. Plan Brief to user — HARD GATE (COMPLEX/MEDIUM; SIMPLE skips). See phase1-planning.md Step 4c-4.

4a. Design options — required scan (skip only for pure refactoring/bug fixes). Scan every task for UX or architectural forks; for each fork present 2-3 concrete options via AskUserQuestion (ASCII wireframes / flow diagrams), max 3 decision points per feature, log choices in DECISIONS.md. If no forks were found, state explicitly in the run log: "Step 4a: scanned N tasks, no user-facing forks detected."

4b. Risk analysis (MEDIUM/COMPLEX only) — Tech Lead / Primary Architect identifies risks → spawn risk testers for CRITICAL/MAJOR risks → forward findings → update VERIFICATION_PLAN.md with mitigations.

5. Spawn team — reviewers (on COMPLEX too, after the architects hand over) + coders with gold standard block + write state.md for compaction resilience.

Phase 2: Execution — Monitor Mode

Full details: references/phase2-monitoring.md

Lead's role is MINIMAL in coordination — but not silent. Coders communicate directly with reviewers and tech-lead via SendMessage. Lead only:

• Prints a progress feed line for every meaningful event (see Progress Feed table in phase2-monitoring.md)
• Tracks progress in state.md (task status updates)
• Spawns new coders when tasks complete and unassigned work remains (one task per coder — they stand down after it)
• Rotates one reviewer every 3 completed tasks, round-robin, so reviewers do not accumulate the whole run
• Handles STUCK/QUESTION/REVIEW_LOOP escalations
• Detects a stalled teammate from the run ledger and the engine process — never by polling on a timer — and replaces it with a fresh finisher instead of doing the work itself
• Transitions to Phase 3 when ALL coding tasks complete

Lead does NOT: read code, review code, run tests, notify reviewers, or forward messages between team members.

Compaction recovery: If context is lost, read .claude/teams/{team-name}/state.md — it contains the current phase, team roster, task statuses, and executable instructions for what to do next.

Output format: the "now → after" table

The report is read by a product person, not an engineer. Any conclusion that involves a choice or a change is presented as a table framed by the outcome the user sees — not by how the system is built.

When there is a fork (something must be chosen):

Below the table, a "Why" block: one line per option (what it wins, what it costs). Then one line: "Recommend X, because …".

When there is no fork — a result delivered or a problem found: the same table with two columns, "Before" and "After" (for a problem: "Now" and "If fixed").

Rules for filling it in:

• Rows are real user situations, never system components. "Scanned a barcode and typed 73 g", not "the barcode_service handler".
• Cells say what the person will see, concretely and with numbers: "calories for 60 g instead of 73", not "incorrect calculation".
• The "Now" column is mandatory — without a baseline the options have nothing to compare against. If the thing doesn't exist yet, write "doesn't exist".
• Include at least one edge-case row: typo, empty input, error. That is usually where the options actually diverge.
• 2-4 rows, 2-3 options. More means the thinking isn't finished and the choice is being dumped on the reader.
• Name options by meaning ("trust the person" / "trust the package"), never "Option 1/2".

No fork and no change means no table: one line saying what you're doing and why. Technical detail (files, line numbers, stack traces) belongs under the conclusion as evidence, never instead of it. Write the table in the language the user is speaking.

Phase 3: Completion & Verification

Full details: references/phase3-verification.md

Execute in order:

1. Conventions update — assign the conventions task to a coder.

2. Cross-task consistency check — Tech Lead (MEDIUM), or a one-shot Explore agent over the combined diff (SIMPLE/COMPLEX).

3. Completion gate — verify .conventions/ exists and was modified this session.

4. Integrated verification (team still alive) — parse VERIFICATION_PLAN.md → pre-flight check → spawn ci-verifier + browser-verifier + spec-verifier in parallel → fix-verify loop (max 3 iterations) → report to VERIFICATION_REPORT.md. See phase3-verification.md 5a-5f.

5. Legacy cleanup (team still alive) — HARD STEP: always run the scan, even if LEGACY_REPORT.md is empty; the user decides per item (Delete / Keep / Later). See phase3-verification.md Step 6.

6. Shutdown — print summary (including legacy cleanup results), shutdown team, TeamDelete, present Human Checks to user.

Everything Important Goes to a File

Write the file first, then send a short message pointing at it — a result that exists only in a message or an agent's context is a result you can lose. Messages carry the verdict and the path; the detail lives in the file.

Per-run artifacts live in .claude/teams/{team-name}/:

Rules:

• Reviewers may Write only inside reports/. Their read-only boundary on source code is unchanged and absolute.
• Never delete these artifacts — when a finding turns out to be wrong, they are the only way to tell what happened.

Key Rules

• Gold standards in every coder prompt — coders MUST receive canonical examples as few-shot context. This is the #1 lever for code quality.
• Escalation, not silent deviation — when a pattern doesn't fit, coders escalate to Tech Lead / Primary Architect. Every approved deviation is documented in DECISIONS.md.
• One file = one coder — never assign overlapping files to different coders.
• Definition of Done — defined in VERIFICATION_PLAN.md (the single "is it done?" document).
• Verify before shutdown — all auto-checks must pass (or be exhausted after 3 fix attempts) before declaring completion.
