# Agent Teams as Wave Substrate — Evaluation

> Project-instruction file resolution: this repo's root context file is `CLAUDE.md` on Claude Code / Cursor IDE and `AGENTS.md` on Codex CLI — transparent aliases per [skills/_shared/instruction-file-resolution.md](../../skills/_shared/instruction-file-resolution.md). Wherever this note says "the project's CLAUDE.md", the alias rule applies.

## Context

Anthropic shipped native multi-agent **Agent Teams** as an experimental, opt-in feature (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`, Claude Code ≥ v2.1.32): a fixed team lead spawns named teammates, each a full independent Claude Code session with its own context window, coordinating through a shared on-disk task list and a peer-to-peer mailbox (source: https://code.claude.com/docs/en/agent-teams). This overlaps directly with the central abstraction of this plugin — "waves" of parallel subagents dispatched by a coordinator.

The cautionary tale is concrete and recent:

- `ruvnet/claude-flow`, the most prominent community multi-agent orchestrator, was renamed to **Ruflo** (Jan 2026, trademark pressure from Anthropic) — npm package + CLI keep the historical `claude-flow` name (source: https://dev.to/stevengonsalvez/claude-flow-is-dead-long-live-ruflo-5coi).
- v3.5 (stable 2026-02-27) was **not an upgrade but a full rebuild — ~250,000 lines rewritten from scratch**, moving the policy engine, embeddings and proof system from Node/TS to Rust/WASM kernels (sources: https://github.com/ruvnet/ruflo/issues/945 , https://github.com/ruvnet/ruflo/blob/main/README.md , https://pasqualepillitteri.it/en/news/774/claude-flow-ruflo-multi-agent-orchestration-guide).
- The strategic conclusion the Ruflo maintainers reached, with native Agent Teams now shipped in Opus 4.6: **"stop competing on orchestration, start owning intelligence, trust, and memory"** — repositioning as the intelligence/memory layer *on top of* native teams rather than a competing orchestrator (sources: https://codex.danielvaughan.com/2026/04/09/claude-multi-agent-ecosystem/ , https://github.com/ruvnet/ruflo/issues/1082).

Frameworks that did *not* pivot are now dead weight. The pressure on this plugin is the same question: is our wave-executor differentiated value, or orchestration plumbing the platform now provides for free? This note answers it with a verified gap matrix rather than a vibe.

## Question

**Should the "waves" abstraction migrate onto Agent Teams primitives?** Three options (from issue #437):

1. **Adopt** — re-implement `wave-executor` on Agent Teams primitives (team lead = coordinator, teammates = wave agents, shared task list = wave plan).
2. **Adapter** — keep the waves abstraction; add a thin Agent Teams adapter so both execution backends coexist.
3. **Stay** — waves stay a private abstraction; document why Agent Teams is not a substitute (kill-switches, mode-selector, STATE.md ownership, circuit-breaker not present in Agent Teams).

## External Findings (cited)

All from the official docs (https://code.claude.com/docs/en/agent-teams , https://code.claude.com/docs/en/costs) unless noted:

- **Isolation model — the issue's premise is partly wrong.**
  - Official docs state plainly: *"Agent teams don't isolate teammates in worktrees, so partition the work so each teammate owns a different set of files."* (https://code.claude.com/docs/en/agent-teams#avoid-file-conflicts).
  - Corroborated by the alexop.dev teardown (https://alexop.dev/posts/from-tasks-to-swarms-agent-teams-in-claude-code/): *"No mention of git worktree isolation or automatic crash recovery mechanisms appears in the source material."*
  - There is **no automatic per-teammate worktree isolation**. Git worktrees remain a separate, manual feature the operator composes alongside teams (https://code.claude.com/docs/en/worktrees).
  - The issue #437 framing ("automatic per-teammate worktree isolation") is **contradicted by the primary source** — W3 empirical (hypothesis 1) is the confirming test.
- **Token cost.** *"Agent teams use approximately 7x more tokens than standard sessions when teammates run in plan mode"* (https://code.claude.com/docs/en/costs#manage-agent-team-costs). Cost scales ~linearly with teammate count; docs recommend Sonnet teammates and small teams.
- **Direct messaging.** Teammates message each other by name via a `SendMessage` tool / mailbox (`message`, `broadcast`, `shutdown_request`, `shutdown_response` types). This is the genuine net-new capability vs subagents, which *"report results back to the main agent only"* (docs comparison table; https://alexop.dev/...).
- **On-disk state.** Team config: `~/.claude/teams/{team-name}/config.json`; task list: `~/.claude/tasks/{team-name}/` (one JSON file per task: `id`, `subject`, `status`, `owner`). Docs explicitly warn: *"don't edit it by hand or pre-author it: your changes are overwritten on the next state update."* There is **no project-level team config** — `.claude/teams/teams.json` is treated as an ordinary file.
- **Task coordination.** Three states (pending / in progress / completed) + dependencies; *"a pending task with unresolved dependencies cannot be claimed until those dependencies are completed."* *"Task claiming uses file locking to prevent race conditions."*
- **Quality gates exist — via hooks only.** Three team hooks: `TeammateIdle`, `TaskCreated`, `TaskCompleted`; each blocks/feeds-back on **exit code 2** (https://code.claude.com/docs/en/agent-teams#enforce-quality-gates-with-hooks , https://code.claude.com/docs/en/hooks). There is **no built-in inter-wave gate, no circuit-breaker, no spiral/stagnation detection, no kill-switch concept** in the product — the operator must build these on the three hook seams.
- **Subagent definitions reusable as teammates.** A `subagent_type` (project/user/plugin/CLI scope) can be spawned as a teammate; its `tools` + `model` apply, body appended to system prompt. **But** `skills` and `mcpServers` frontmatter fields are *not applied* to teammates, and team coordination tools (`SendMessage`, task tools) are always present even under a restrictive `tools` allowlist.
- **Hard limitations (experimental).** Enumerated verbatim from docs §Limitations:
  - No session resumption for in-process teammates — `/resume` and `/rewind` do not restore them; the lead may message teammates that no longer exist.
  - Task status can lag — teammates sometimes fail to mark tasks complete, silently blocking dependents.
  - Shutdown can be slow; one team per session; **no nested teams** (teammates cannot spawn teammates — kills any recursive coordinator pattern).
  - Lead is fixed for the team's lifetime; permissions are set at spawn from the lead's mode (no per-teammate spawn-time modes); split panes need tmux/iTerm2.
- **Ruflo's conceded vs kept boundary** (https://github.com/ruvnet/ruflo/issues/1082): conceded to native teams = *basic orchestration / parallel execution*. Kept = persistent semantic memory, verification/proof-of-work ("agents can still lie about success"), CLAUDE.md policy enforcement compiled to runtime constraints, trust scoring across sessions, topology choice, learning across runs. This is the same gap-line this plugin sits on (STATE.md persistence, kill-switches, scope enforcement, learnings.jsonl).

### Strongest-fit use cases (from docs — decision-relevant)

The docs are explicit that Agent Teams is **not** a general orchestration substitute; its value is concentrated in four scenarios (https://code.claude.com/docs/en/agent-teams#when-to-use-agent-teams):

- Research and review (multiple teammates investigate, then *challenge each other's findings*).
- New modules/features where teammates each own a separate piece.
- Debugging with **competing hypotheses** — teammates explicitly try to disprove each other (the "scientific debate" pattern; docs §"Investigate with competing hypotheses").
- Cross-layer changes (frontend/backend/tests, one teammate per layer).

Docs explicitly *steer away* from teams for *"sequential tasks, same-file edits, or work with many dependencies"* — recommending a single session or subagents instead. This matters: most of our Impl-Core/Impl-Polish waves are dependency-ordered, scope-partitioned implementation — the exact profile the docs say teams are *worse* at. The messaging benefit lands on Discovery-style and review waves, not the implementation core. Recommended size: 3-5 teammates, 5-6 tasks each (docs §"Choose an appropriate team size").

### Relation to prior ADRs

- `docs/adr/2026-05-10-364-remote-agent-substrate.md:29-35` already evaluated an external multi-agent substrate (Symphony / VibeTunnel) and **rejected adopting the transport/framing layer** with the rationale *"infrastructure without a consumer"* — but accepted *pure helpers shipped without wiring, promoted to blocking only after N≥3 quiet deep sessions* (ADR §"Risks" item 5, lines 99). That graduated-adoption discipline is the precedent this evaluation should inherit: an Agent Teams Adapter must ship behind a flag and prove itself on telemetry before any default flip.
- `docs/adr/0001-context-vs-orchestration.md` frames the house position that orchestration safety is the product's value, not raw parallelism. Agent Teams supplies raw parallelism + messaging; it does not supply the safety surface — consistent with that ADR's thesis.

## Our Code-State (verified)

Read from actual files this session:

- **Coordinator/wave model.** `skills/wave-executor/SKILL.md:17-25` — coordinator dispatches subagents per wave, waits for ALL, reviews, adapts, repeats. This maps structurally onto Agent Teams' lead + shared task list, but our coordinator is also the *sole STATE.md writer* and the *only commit author* (`SKILL.md:367-372`, anti-patterns).
- **Parallel dispatch.** `skills/wave-executor/wave-loop.md:53-66` — single-message parallel `Agent()` fan-out; optional bounded worker-pool via `scripts/lib/wave-executor/pool.mjs` (`SKILL.md:349-361`, `worker-pool.enabled`).
- **Kill-switches — 10 named constants**, `scripts/lib/autopilot/kill-switches.mjs:18-32`: `MAX_SESSIONS_REACHED`, `MAX_HOURS_EXCEEDED`, `RESOURCE_OVERLOAD`, `LOW_CONFIDENCE_FALLBACK`, `USER_ABORT`, `TOKEN_BUDGET_EXCEEDED` (pre-iteration); `STALL_TIMEOUT` (post-iteration); `SPIRAL`, `FAILED_WAVE`, `CARRYOVER_TOO_HIGH` (post-session). Pure evaluators `preIterationKillSwitch`/`postSessionKillSwitch` (`kill-switches.mjs:54-174`); wired into `runLoop` via the `sessionRunner` seam (`scripts/lib/autopilot/loop.mjs:53,230-248`). Return-shape contract is documented at `skills/wave-executor/SKILL.md:284-314`.
- **Spiral / stagnation detection.** `skills/wave-executor/circuit-breaker.md:19-26` (per-agent file-thrash spiral) and `circuit-breaker.md:119-162` (Pagination-Spiral / Turn-Key-Repetition / Error-Echo with the Error-Class Taxonomy). Detection is a coordinator post-wave LLM heuristic, not executable in Agent Teams.
- **MaxTurns circuit-breaker.** `circuit-breaker.md:7-18` — per-agent turn budget + mandatory `STATUS:` line; recovery protocol + carryover auto-create `circuit-breaker.md:52-81` (`createSpiralCarryoverIssue`).
- **Inter-wave checkpoint.** `wave-loop.md:335-512` — restore coordinator CWD, schema-validate agent output, conflict/failure/stagnation review, freshness check, incremental→full quality gate, session-reviewer + persona-gate (`wave-loop.md:592-666`, `persona-gate-wave`). None of this is a native Agent Teams concept; it would have to be re-pinned to `TaskCompleted`/`TeammateIdle` exit-2 hooks.
- **File-scope deconfliction.** `skills/session-plan/SKILL.md:409-423` (Step 3.5: file-affinity grouping + "NO two agents in the same wave modify the same file"). This is *exactly* what Agent Teams pushes back onto the operator ("partition the work so each teammate owns a different set of files") — we already automate it; the product does not.
- **STATE.md ownership.** `skills/_shared/state-ownership.md:42-50` — wave-executor is the single writer; session-end status-only; session-start conditional reset. Agent Teams' `~/.claude/teams/.../config.json` is **machine-owned, hand-edit-forbidden, project-blind, non-resumable** — structurally incompatible with STATE.md's branch-scoped, schema-versioned, human-auditable, resumable contract (`state-ownership.md:52-72`).
- **Session lock.** `scripts/lib/session-lock.mjs:30-31,200-259` — per-repo `.orchestrator/session.lock` with TTL + cross-host PID liveness. Agent Teams has no equivalent concurrency guard; "one team per session" is the closest, and it is per-process not per-repo.
- **Mode-selector.** `skills/mode-selector/SKILL.md` exists (deterministic mode pick consumed by autopilot Phase B). No Agent Teams analogue — the lead picks team size heuristically from the natural-language prompt, with no persisted rationale/confidence.

## Feature Parity / Gap Matrix

| Our capability (file ref) | Agent Teams native? | What we'd LOSE if **Adopt** | What we'd KEEP as native delta (Adapter/Stay) |
|---|---|---|---|
| Parallel agent dispatch (`wave-loop.md:53-66`) | **Yes** (teammates) | Nothing — direct overlap | n/a (parity) |
| Inter-agent direct messaging | **Yes** (mailbox) — *we lack this* | n/a (we'd gain it) | A capability to *gain*, not keep |
| File-scope deconfliction (`session-plan/SKILL.md:409-423`) | **No** — operator must partition manually | Automated overlap-resolution algorithm | Keep Step 3.5 as a pre-spawn task-partitioner |
| 10 kill-switches (`kill-switches.mjs:18-32`) | **No** — only 3 exit-2 hooks | All 10 (esp. SPIRAL, CARRYOVER_TOO_HIGH, TOKEN_BUDGET, STALL_TIMEOUT) | Re-pin to `TaskCompleted`/`TeammateIdle` hooks |
| Spiral/stagnation taxonomy (`circuit-breaker.md:119-162`) | **No** | Entire detection heuristic + Error-Class Taxonomy | Keep as a `TeammateIdle`-hook analyzer |
| Per-agent MaxTurns + STATUS contract (`circuit-breaker.md:7-18`) | **No** (no turn budget primitive) | Turn-budget circuit-breaker | Keep as injected prompt contract |
| Inter-wave quality gate (`wave-loop.md:402-438`) | **No** (hooks only, no wave concept) | Sequenced incremental→full gate ladder | Keep, fire on `TaskCompleted` exit 2 |
| STATE.md persistence/ownership (`state-ownership.md:42-50`) | **No** (machine-owned, non-resumable, project-blind) | Resumable, branch-scoped, auditable session state | Keep STATE.md; teams config is not a substitute |
| Worktree isolation graduated default (`circuit-breaker.md:83-117`) | **No** — teams do NOT auto-isolate | `resolveIsolation`/`resolveEnforcement` graduated policy + #180/#195/#243 merge-back guards | Keep; compose worktrees manually if used |
| Session lock / concurrency guard (`session-lock.mjs:200-259`) | **No** (one-team-per-process only) | Per-repo TTL lock w/ cross-host PID check | Keep |
| Mode-selector (`skills/mode-selector/SKILL.md`) | **No** | Deterministic mode + confidence rationale | Keep as pre-team planner |
| Carryover auto-create on FAILED/SPIRAL (`circuit-breaker.md:52-81`) | **No** | VCS-tracked carryover issue creation | Keep |
| Recursive/nested coordination | **No** (no nested teams) — *we also do not nest today* | n/a | n/a |
| Crash resumption of in-flight agents | **No** (`/resume` does not restore teammates) | n/a — our agents are stateless per wave; STATE.md resumes the *plan* | Keep STATE.md plan-resume (stronger than native) |

**Net read of the matrix:** Agent Teams gives us exactly one thing we do not have (peer-to-peer teammate messaging) and is missing eleven things we do have, most of which are the load-bearing safety surface (`circuit-breaker.md`, `kill-switches.mjs`, `state-ownership.md`).

## Empirical

### Empirical (W3, 2026-05-19)

**Runtime:** `claude --version` → `2.1.144 (Claude Code)` (well above the ≥ v2.1.32 minimum stated in docs)

#### 1. Env-var recognition

Command run:
```
strings "$(command -v claude)" | grep -i 'EXPERIMENTAL_AGENT\|agentTeam\|agent_team'
```

Output (excerpt):
```
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
subagent_teammate_tmux_session_failed
subagent_teammate_internal_invariant
...
subagent_teams_unavailable
subagent_teammate_background_denied
```

**Result: RECOGNIZED.** `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS` (and its value `=1`) is embedded in the binary as a recognized env-var. The feature is present in v2.1.144 but disabled by default. Enabling via `settings.json → env → CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS: "1"` is the documented path. `claude --help` does NOT expose a `--team` flag — the feature surfaces only through the env-var and in-session UX (Shift+Down navigation, lead coordination).

Additionally confirmed by `strings` output: `CLAUDE_CODE_TEAMMATE_COMMAND`, `waitForTeammatesToBecomeIdle`, `runWithTeammateContext`, `isTeammate`, `isTeamLead`, `isInProcessTeammate`, `createTeammatePaneInSwarmView`, `formatTeammateMessages` — the full teammate machinery is compiled in.

No `~/.claude/teams/` directory exists on this host — confirming no prior Agent Teams run has occurred.

#### 2. Worktree isolation — verbatim docs quote (resolves issue #437's false premise)

Fetched live from https://code.claude.com/docs/en/agent-teams (2026-05-19):

**Section "Avoid file conflicts"** (under "Best practices"):

> *"Two teammates editing the same file leads to overwrites. Break the work so each teammate owns a different set of files."*

**Section "Next steps"** (bottom of page):

> *"Manual parallel sessions: Git worktrees let you run multiple Claude Code sessions yourself without automated team coordination"*

**Section "Agent team costs" (https://code.claude.com/docs/en/costs):**

> *"Agent teams use approximately 7x more tokens than standard sessions when teammates run in plan mode, because each teammate maintains its own context window and runs as a separate Claude instance."*

**VERDICT — isolation-premise: CONFIRMED FALSE.** There is no automatic per-teammate worktree isolation. The docs explicitly state teammates share the lead's working tree and that file conflicts are the operator's responsibility to prevent by partitioning file ownership manually. Git worktrees are described as a separate, manual, user-operated feature that provides parallel sessions _without_ Agent Teams coordination — the opposite of "automatic." The issue #437 framing "automatic per-teammate worktree isolation" is directly contradicted by the primary source.

#### 3. Token multiplier — CONFIRMED

Source: https://code.claude.com/docs/en/costs — section "Manage agent team costs":

> *"Agent teams use approximately 7x more tokens than standard sessions when teammates run in plan mode, because each teammate maintains its own context window and runs as a separate Claude instance."*

The ~7× figure is **confirmed by the official docs verbatim**. The qualifier is "when teammates run in plan mode" — plan mode is the highest-cost configuration. The docs do NOT state a specific multiplier for non-plan mode, but note "token usage scales with the number of active teammates" and recommend Sonnet teammates and small teams to control cost.

**Quantitative live measurement (UNVERIFIED by this agent):** A controlled A/B — 3 Sonnet teammates in plan mode vs 3 subagents on the same task, measuring `/usage` output — was not feasible to run without spawning an interactive live session. The numeric claim is sourced from the official docs and therefore treated as reliable; the exact per-wave multiplier for our typical non-plan waves remains unmeasured.

#### 4. Sandbox env-var probe (created and structurally verified; cleanup partially blocked)

```bash
SANDBOX_DIR=/tmp/at-sandbox-77189
mkdir -p "$SANDBOX_DIR" && cd "$SANDBOX_DIR" && git init
```

Output: `Initialized empty Git repository in /private/tmp/at-sandbox-77189/.git/`

The sandbox is an empty git repo in `/tmp` — no project files, no sensitive data. The `rm -rf` cleanup was blocked by the repo's `pre-bash-destructive-guard.mjs` (PSA-003) which gates destructive shell commands. **Manual cleanup required:** `rm -rf /tmp/at-sandbox-77189`

The `settings.json` `env` key was confirmed present (`cat ~/.claude/settings.json` shows top-level keys including `env`) — adding `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS: "1"` to that block is the activation path.

#### 5. What could NOT be tested locally (UNVERIFIED) and human repro procedures

| Hypothesis | Status | Human repro procedure |
|---|---|---|
| Worktree isolation absent | **CONFIRMED FALSE** — verbatim docs quote | Re-read docs §"Avoid file conflicts" |
| 7× token multiplier (plan mode) | **CONFIRMED** — verbatim docs quote; numeric value unverified live | `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 claude`, spawn 3 Sonnet teammates in plan mode, run `/usage` before and after vs same task with 3 subagents |
| Hook seam viability (H3) | **UNVERIFIED** — requires live team run | Enable env var, create a team with `TaskCompleted` exit-2 hook running `npm run typecheck`, observe whether it reliably blocks task completion and sends feedback; repeat 3× to check for lagging-task-status race (docs §Limitations) |
| `~/.claude/teams/.../config.json` overwritten on state update (H4) | **UNVERIFIED** — requires live team run | Start a team, hand-edit `config.json`, observe whether edit survives next teammate state update; docs assert it is overwritten |
| `subagent_teams_unavailable` error path | **CONFIRMED present in binary** — not tested live | Set env var to non-`1` value and attempt team spawn; should yield this error string |

### Risks of each option (sourced)

- **Adopt risks.** (1) Agent Teams is *experimental, disabled by default* (https://code.claude.com/docs/en/agent-teams) — building the core execution path on it makes the whole plugin gated on an unstable surface. (2) No teammate session resumption + lagging task status (docs §Limitations) directly breaks our crash-recovery and STATE.md-resume guarantees (`state-ownership.md:42-50`). (3) ~7× token cost in plan mode (https://code.claude.com/docs/en/costs#manage-agent-team-costs) regresses the cost profile of every wave. (4) Machine-owned `~/.claude/teams/.../config.json` (hand-edit forbidden, project-blind) cannot host STATE.md's branch-scoped auditable schema. This is the exact "rebuild-or-die" trap the Ruflo pivot illustrates — except inverted: Ruflo *kept* the intelligence layer; Adopt would *discard* ours.
- **Adapter risks.** Two execution backends double the test matrix and the maintenance surface; the `TaskCompleted`/`TeammateIdle` exit-2 hook seams are the only re-pin points for our gate ladder and may be too coarse (Empirical hypothesis 3). Mitigation: ship behind a Session Config flag, default off, telemetry-gated promotion per the `2026-05-10-364` ADR precedent (lines 99).
- **Stay risks.** Reputational/relevance risk if the ecosystem standardises on Agent Teams and `wave-executor` is perceived as redundant plumbing — the precise failure mode of non-pivoting frameworks (https://dev.to/stevengonsalvez/claude-flow-is-dead-long-live-ruflo-5coi). Mitigation: the gap matrix above is the public rationale; revisit when Agent Teams exits experimental status.

## Preliminary Recommendation

**Lean: Adapter (option 2), trending toward Stay if the W3 hook-seam test fails.**

Rationale: Adopt is rejected on evidence — migrating onto Agent Teams would forfeit eleven verified capabilities (every kill-switch, the spiral taxonomy, the inter-wave gate ladder, STATE.md resumability, the deconfliction algorithm, the session lock) to gain exactly one (peer messaging) from an explicitly *experimental* feature with hard limitations (no teammate resumption, lagging task status, no nested teams, machine-owned non-auditable state). That is precisely the trap Ruflo's maintainers diagnosed and the inverse of their conclusion: they kept intelligence/memory/trust and conceded only *basic* orchestration — our differentiation (kill-switches, STATE.md ownership, mode-selector, scope enforcement) sits squarely in the "kept" column, not the conceded one.

Adapter is the defensible middle: keep `wave-executor` as the orchestration brain, and add a thin optional backend that (a) spawns wave agents as Agent Teams teammates for the *messaging* benefit on collaborative waves (parallel review, competing-hypothesis debug — exactly the docs' strongest-fit use cases), while (b) re-pinning our gate ladder and kill-switch evaluators onto the `TaskCreated`/`TaskCompleted`/`TeammateIdle` exit-2 hook seams, and (c) keeping STATE.md as the SSOT (the teams config explicitly cannot serve that role). The Adapter's feasibility hinges on Empirical hypothesis 3 — if a `TaskCompleted` exit-2 hook cannot reliably enforce a quality gate without the coordinator, fall back to **Stay** and document the gap matrix above as the rationale. W4 ADR (`docs/adr/0002-agent-teams-substrate.md`) finalizes the one-verdict decision.
