# Voyage-vs-CC Balance Analysis

**Status:** Analysis — recommendations only, operator-gated before any implementation.
**Date:** 2026-06-20. **Baseline:** Claude Code 2.1.183 (latest; 2.1.182 never shipped).
**Charter:** `docs/voyage-vs-cc-balance-charter.md`. **Method substrate:** Dynamic Workflow (`wf_41bb3936-e6d`, 96 agents, ~2.97M subagent tokens, 4.6 min) + inline scout + an over-keeping meta-critic.

---

## TL;DR

- **Voyage's existence is justified by ONE thing the audit confirms end-to-end:** typed, versioned, cross-stage/cross-session **structured-artifact handovers** (brief → research → plan → execute → review → continue) plus **multi-session discipline**. CC 2.1.183 has no native analog for a semver-stable public artifact contract or a typed work-state checkpoint. This matches the plugin's own CLAUDE.md self-admission and the operator's primary real use (large tasks across many sessions).
- **It is NOT justified by the swarm-relieves-context claim** (measured Δ ≈ 0, unchanged here) and **not by re-implementing CC engines.** Wherever CC ships the engine, Voyage's only defensible role is a *thin policy layer that lowers the expertise bar* — never a re-implementation.
- **Disposition tally (35 capabilities, post-adversarial):** KEEP 25 · THIN_WRAP 6 · SIMPLIFY 4 · DROP→NATIVE 0.
- **The zero-DROP result is over-keeping at the edges.** A meta-critic flags **4 genuine downgrade candidates** (V09 Gemini-bridge, V15 text-export variants, V32 observability export, V35 dormant synthesis-agent). Acting on all of them trims the edges; it does **not** move the headline.
- **Nothing recommended here breaks Handover 1** (the public brief contract). Every operator-pinned decision the analysis brushes is flagged, never silently overridden.

---

## 1. Method & evidence base (Phase 0–1)

### 1.1 Post-2.1.181 CC delta (Verification #4)

Latest CC = **2.1.183** (June 19 2026). **2.1.182 never existed** (skipped build). 2.1.183 = bugfixes + auto-mode git safety guards only. **No new features touch the Workflow tool, plan mode, Artifacts, subagent nesting, or session checkpointing.** Several 2.1.183 fixes actually *repair* Voyage swarm failure modes (subagent-spawn 400s, empty WebSearch-in-subagent, silent thinking-only completions, tmux teammate launch, background-task premature termination) — no Voyage code change needed. **Conclusion: the CC-native overlap baseline is unchanged from the 2.1.181 decision matrix.**

### 1.2 Anchor verdicts carried in (not re-derived)

| Prior finding | Verdict | Source |
|---|---|---|
| Sub-agents can nest ≤5 deep | true since CC 2.1.172 (old "harness hides Agent tool" premise is FALSE) | `cc-upgrade-2.1.181-decision-matrix.md` CC-01 |
| Delegate the orchestration loop to a sub-agent (CC-26) | **lean NO** — only upside is main-context relief, measured Δ=0; new proliferation-classifier risk | `T1-cc26-delegated-orchestration.md` |
| Workflow tool as substrate (CC-27) | **selective hybrid** — schema-contract win real; wholesale swap DECLINED | `T2-cc27-workflow-substrate.md` |
| Synthesis delegated to a sub-agent (T1 PoC) | **Δ main-context = 0.0%** (exploration already runs foreground; digest returns on top) → dormant | `T1-synthesis-poc-results.md` |
| Flagship "swarm relieves context" | **unproven**; structured-artifact handovers are the load-bearing benefit | root `CLAUDE.md` (verbatim self-admission) |

### 1.3 The two decision axes

- **Axis A — Duplication:** does CC 2.1.183 do this natively? does it do it *better*?
- **Axis B — Expertise-bar:** does Voyage's wrapper let a non-CC-expert get the value *without* knowing CC internals?

**Disposition vocabulary:** KEEP (Voyage-unique/clearly better) · THIN_WRAP (CC is the engine; keep a thin accessibility layer, delegate the engine) · DROP→NATIVE (CC better + no real expertise gap; remove + document native path) · SIMPLIFY (keep, shed complexity CC now handles).

**The tension the analysis was forced to resolve per capability:** a feature CC does "better" raw can still deserve THIN_WRAP if raw CC requires expertise — *accessibility can justify a wrapper, never a re-implementation.*

### 1.4 How the classification ran

35 canonical capabilities (consolidated from 42 command-level + ~30 infra inventory rows). Each ran a 3-stage pipeline: **(A)** CC-overlap map (sonnet) → **(B)** A×B classification → disposition (opus) → **(C)** adversarial verify of every KEEP/DROP→NATIVE (opus, high effort). Stage-B/C agents read the actual Voyage code (validators, hooks, command prose) and cite `file:line`. A final **over-keeping meta-critic** then attacked the zero-DROP outcome holistically (§4).

---

## 2. The balance thesis

Voyage sits on a host (CC) that has absorbed most of what a 2024-era "agent orchestration" plugin differentiated on: parallel sub-agent spawn, nesting, native `effort:`, plan mode, MCP, hooks, the Workflow tool. The audit's structural finding is that **CC absorbed the *primitives*, not the *contracts*.** Across all 35 capabilities, every CC overlap is `cc_partial` or `cc_absent` — CC ships the spawn/ask/hook/MCP engine, but never:

- a **versioned, semver-stable, PUBLIC artifact schema** an unrelated upstream producer can target (Handover 1),
- a **typed cross-session work-state checkpoint** with auto-discovery and zero-confirm resume (Handover 7),
- a **standing per-handover validator library** that gates the pipeline on written-artifact frontmatter,
- or the **opinionated domain policy** (research angles, review taxonomy, manifest predicates) a user would otherwise hand-author every run.

**So the balance is:**

- **Where CC has no engine (most KEEPs)** — brief contract, plan-schema enforcement, manifest audit, progress/resume, session-state, triangulation, the handover contract itself — Voyage is genuinely additive. KEEP.
- **Where CC has the engine (the THIN_WRAPs)** — research/exploration/reviewer swarms, the research interview, the Gemini bridge, observability — Voyage's job is to **ride the native primitive and add only the thin policy**, never to re-host the engine. THIN_WRAP, with a standing obligation to delegate the engine to CC.
- **Where the wrapper's own contract layer is thin or empty (the over-keeping edge)** — a "do-not-editorialize" pass-through agent, text reformatting, a re-hosted telemetry collector, a dormant measured-dead agent — the accessibility defense is rhetorical, and these are the DROP/downgrade candidates.

---

## 3. Phase 3 disposition matrix (Verification #1)

Each capability appears exactly once. Inventory count (35) = matrix rows (35). Axis A: `nb`=cc_native_better, `eq`=cc_native_equal, `pt`=cc_partial, `ab`=cc_absent. Axis B gap: H/M/L/none. **Adv** = per-capability adversarial verdict (— = not in KEEP/DROP scope). **B** = acting on it would change a handover contract. **P** = touches an operator-pinned decision.

## 4. The zero-DROP finding & over-keeping meta-review (Verification #5)

**The honest gap:** the per-capability adversarial pass challenged all 26 KEEP classifications (25 upheld, 1 revised: V33 KEEP→SIMPLIFY) — but because the classification produced **zero DROP→NATIVE**, the charter's "challenge ≥1 DROP→NATIVE" criterion had nothing to operate on. A self-audit concluding "drop nothing" is the exact pattern a skeptic should distrust. So a dedicated **over-keeping meta-critic** attacked the outcome and the recurring "primitive vs typed-contract" defense.

**Meta-critic verdict:** the zero-DROP outcome is **over-keeping at the edges**. The "primitive vs typed-contract" distinction is *load-bearing* for V08/V11/V24 (real policy a user must re-author every run) but *rhetorical* where the contract layer is itself thin or empty. Four downgrade candidates:

| Cap | Workflow said | Meta-critic says | Native path / what's lost | Contested? |
|-----|---------------|------------------|---------------------------|-----------|
| **V09** Gemini bridge | THIN_WRAP | **DROP→NATIVE** | Call `gemini-mcp` tools inline; agent explicitly *doesn't* reason → opus-on-glue is pure waste. The classify pass *also* flagged opus wasted here. | Low — both passes agree |
| **V15** plan export (pr/issue/markdown) | SIMPLIFY | **DROP the 3 text variants** | Ask auto-mode to reformat ad-hoc; only `--export headless` (=decomposition) survives, and that's V16 wearing a flag. | Low |
| **V32** observability export | THIN_WRAP | **DROP→NATIVE candidate** | Point OTEL env vars at a standard OTLP collector (which owns allowlists/egress); exporters re-host the collector. | **High** — code-verified pass says SSRF/path/field guards are net-new; this is a genuine direct-export-vs-collector architecture choice. Operator decision. |
| **V35** dormant synthesis-agent | SIMPLIFY | **DROP the dormant agent** | It's already dead (Δ=0, wired to nothing); orchestrator docs are docs, not capabilities. | Low |

**Caveat for the operator:** the meta-critic reasoned from the disposition table, not from re-reading the code, whereas the per-capability passes cite `file:line`. Treat V32 as genuinely contested. V09/V15/V35 are low-contest because both layers of analysis converge.

**Bottom line (meta-critic, verbatim sense):** dropping V09 + V15-text + (probably) V32 and demoting V35's dead agent *trims the edges decisively but does not move the headline* — the typed-handover + multi-session core is untouched and remains the only thing that justifies the plugin's existence.

---

## 5. Target-form for Voyage

What Voyage should *be*, given modern CC:

1. **A contract layer, not an orchestration engine.** Lead with the 7 typed handovers + multi-session discipline (V28/V29 + the validators V34). Stop marketing swarm-context-relief; it's measured Δ≈0.
2. **A thin accessibility skin over native CC engines** for everything CC now does well: research/exploration/reviewer swarms should *visibly delegate* to native parallel Agent spawn + AskUserQuestion + Stop hooks, adding only the opinionated policy (angles, roles, taxonomy, schemas). Never re-host an engine.
3. **Opinionated defaults that encode best practice** so a non-CC-expert gets disciplined planning/execution/review without knowing the harness — this is the durable Axis-B justification, confirmed `high_gap` on the execution and review cores.
4. **Lean at the edges:** no pass-through agents paying opus to forward bytes (V09), no hand-written reformatters for what auto-mode does ad-hoc (V15-text), no re-hosted telemetry collector unless the direct-export design is a deliberate, defended choice (V32), no dormant agents padding the capability count (V35).

---

## 6. Prioritized change backlog (Verification #6)

All items are **operator-gated** (scope-guard: analysis only). Tagged **[non-breaking]** / **[breaking]** and **[pinned]** where they touch an operator-pinned decision.

### Tier 1 — over-keeping trims (highest value, mostly non-breaking)

1. **[non-breaking][pinned]** **V09** — drop `gemini-bridge` as an opus agent; call `gemini-mcp` tools inline (or, if kept, downgrade opus→sonnet, since it explicitly does not reason). Touches the 24-opus pin → flag.
2. **[non-breaking]** **V15** — drop the `pr`/`issue`/`markdown` export variants (auto-mode does the reflow ad-hoc); keep `--export headless` and relabel it as the decomposition entry it actually is.
3. **[non-breaking, contested]** **V32** — decide direct-export-vs-collector explicitly. If a standard OTLP collector is acceptable, drop the custom exporters + reimplemented guards to native OTEL env-var passthrough; if direct export is a deliberate requirement, keep and document *why* (this is the one genuinely contested call).
4. **[non-breaking][pinned]** **V35** — strip the dormant `synthesis-agent`'s `model:opus`/`effort:high` frontmatter (or collapse it to a docs note); reclassify the 3 orchestrator reference docs as docs, not capabilities. Touches the 24-opus pin → flag.

### Tier 2 — THIN_WRAP hygiene (ensure delegate-the-engine, non-breaking)

5. **[non-breaking]** Audit V07/V08/V11/V24 implementations to confirm they ride native parallel-spawn / AskUserQuestion rather than hand-rolling, keeping only the policy layer. (Mostly already true — this is a standing guard against engine re-implementation, not a known defect.)
6. **[non-breaking][pinned]** Reconsider opus-for-all on mechanical/retrieval roles: V11 retrieval agents (already `effort:medium`), V16 `session-decomposer` (dependency parsing is mechanical), V08 researchers. Each touches the 24-opus pin → flag, don't override.

### Tier 3 — surfaced risks (no action mandated)

7. **[non-breaking][pinned]** **V30** — the `economy` profile's Jaccard floor (0.55) is grounded in parked synthetic fixtures (Step 17 calibration deferred). It is self-declared experimental; either calibrate or label clearly. → **RESOLVED (S34): label, not calibrate.** Empirical calibration is v4.2-budget-gated ($60–120, unauthorized); instead `lib/profiles/economy.yaml` now carries `experimental: true` (validator type-checks it) and every profile doc flags the `economy` row. Pinned in `profile-validator.test.mjs` + `doc-consistency.test.mjs` — the flag must track the calibration's `parked-synthetic` status.
8. **[non-breaking]** **V01** — minor: delegate the literal Q&A turn-taking to AskUserQuestion rather than a hand-rolled selection loop (internal hygiene; does not change the framing-gate or reviewer contract).

### Explicitly NOT recommended

- **No change to Handover 1** (brief schema) — the only public contract; any change is breaking. V02/V03/V05 stay.
- **No wholesale Workflow substrate swap** (CC-27 DECLINED stands); keep V27 as opt-in only.
- **No delegated-orchestration redesign** (CC-26 lean-NO stands; Δ=0).
- **No reopening** of the premium-default-profile or framing-gate operator pins — flagged where touched, never overridden.

## 7. Verification checklist (charter §Verifisering)

| # | Criterion | Status |
|---|-----------|--------|
| 1 | Each capability appears exactly once with disposition + rationale + evidence-ref; inventory count == matrix rows | ✅ 35 == 35 (§3) |
| 2 | Each "CC duplicate / does better" cites a specific CC feature + version | ✅ `cc_citation` per row (e.g. AskUserQuestion 2.0+, parallel Agent 2.1.154+, nesting 2.1.172, Workflow 2.1.154+, `effort:` 2.1.154, PreToolUse ~2.1.97, PreCompact 2.1.105) |
| 3 | Each "lowers expertise bar" names the concrete native steps a non-expert would otherwise do | ✅ captured in `expertise_steps_if_native` / `concrete_native_steps_saved` per capability |
| 4 | Post-2.1.181 delta actually run; latest version stated + each new item triaged | ✅ §1.1 — CC 2.1.183, 17 items triaged, none balance-relevant |
| 5 | Adversarial pass challenged ≥1 KEEP and ≥1 DROP→NATIVE, with verdict | ⚠️ 26 KEEPs challenged (1 revised); **zero DROP→NATIVE were produced**, so that half was addressed by the over-keeping meta-critic (§4) which named 4 DROP/downgrade candidates with verdicts. Honest deviation from the literal criterion, documented. |
| 6 | Output ends with a prioritized backlog, each item tagged breaking/non-breaking + operator-gated | ✅ §6 |

---

## 8. Hard constraints honored

- **Trinity asymmetry:** no recommendation changes the brief schema (Handover 1). Voyage stays unaware of Tier 2/3. The one capability marked `breaking` (V05, memory-alignment, bound to `brief_version 2.2`) is recommended **KEEP-as-is** — no breaking change proposed.
- **Operator-pinned decisions:** premium default profile, 24-opus agents, framing-gate, plan-critic=10-dim, brief-reviewer=6-dim — all preserved. Where a backlog item brushes a pin (V09/V35 model frontmatter; opus-on-mechanical-roles; economy calibration), it is **flagged `[pinned]` and operator-gated**, never overridden.
- **Analysis only:** every item in §6 requires an explicit operator gate before implementation.

---

## 9. Meta-note (dogfooding the Workflow tool)

Running this analysis *on* the CC Workflow tool produced first-hand evidence for the audit's own V27/V29 rows: the `pipeline()` shape gave clean coverage (35/35, no row dropped), schema-forced output eliminated JSON-parse fragility (the CC-27 F2 win, reconfirmed), and the conditional adversarial stage worked. Costs also reconfirmed: ~2.97M subagent tokens / 96 agents / 4.6 min for a 35×3 fan-out — Workflow is a good substrate for *bounded, verifiable, parallel* fan-out, exactly the ~20% core CC-27 identified, and a poor fit for the ~80% judgment-heavy glue (scout + synthesis, which ran inline in main context here). This is dogfooding of the **Workflow tool**, not of Voyage's pipeline (the latter was declined by the operator).

---

## 10. Decision record — resolved forks (operator, 2026-06-20)

§4/§6 deferred three forks to the operator. All three resolved to the
**conservative** option (preserve the capability / the security code / the
deliberate pin). The model and observability work therefore collapses from
code-deletion to a documentation record; the only real code changes in the
backlog are V15 (export trim, S31) and V30 (economy calibration, S34). These
decisions are now the implemented baseline of the multi-session backlog plan
(`docs/balance-backlog-plan.md`), shipped across S31–S34.

| Fork | Item | Resolution | What changed |
|------|------|------------|--------------|
| **D1** | V09 `gemini-bridge` | **Keep it as an agent.** | No removal / inline-rewiring. The capability count stays 24; its model is governed by D3 (stays opus). |
| **D2** | V32 observability export | **Keep `lib/exporters/*` + `otel-export.mjs`; document the direct-export rationale.** | Doc-only — no deletion of S21 security code. The rationale (preserve the in-process path / SSRF / field-allowlist guards rather than re-host a collector) is recorded in `docs/observability.md` §"Why direct export rather than a native collector". |
| **D3** | 24-agent `model: opus` pin (`40d8742`) | **Keep the pin firm.** | Document-only. opus on V09 (glue — does not reason), V35 (dormant `synthesis-agent`), V11 (retrieval agents, already `effort:medium`), V16 (`session-decomposer`, mechanical parsing), and V08 (researchers) was reconsidered for a sonnet downgrade and **kept opus**. **No agent frontmatter is changed** — `tests/lib/agent-frontmatter.test.mjs` remains the structural source-of-truth and is untouched. |

**Inventory framing (V35 doc half, reconciled).** The "24 agents" headline is
**21 spawnable + 3 orchestrator reference docs**. The three orchestrators
(`planning-/research-/review-orchestrator`) document the inline `/trek*`
workflow and are not spawned as sub-agents. Of the 21 spawnable, one —
`synthesis-agent` — ships **dormant** (Δ≈0, wired to nothing;
`docs/T1-synthesis-poc-results.md`). Reconciled across `README.md`,
`CLAUDE.md`, and this doc; pinned in `tests/lib/doc-consistency.test.mjs` (S33).

**V30 outcome (S34, the lone Tier-3 code item).** The economy-calibration fork
also resolved conservatively: **label, do not calibrate.** The empirical run is
v4.2-budget-gated ($60–120, unauthorized) and was never in scope here. Instead
`economy`'s experimental status — previously prose-only in `docs/profiles.md` —
now lives in the profile **data** (`lib/profiles/economy.yaml experimental: true`,
type-checked by the profile-validator) and on every profile-doc `economy` row,
pinned so the flag tracks the calibration's `parked-synthetic` status and is
dropped in the same change that lands real calibration. This closes the backlog:
all 8 §6 items disposed across S31–S34 (2 code: V15+V30; the rest doc/audit).

**Still explicitly NOT done** (out of scope, per the plan): no `gemini-bridge`
removal (D1), no exporter deletion (D2), no model downgrade (D3), no Handover-1
change, no Workflow substrate swap (CC-27 declined), no delegated-orchestration
redesign (CC-26 lean-NO), no reopening of the premium-default / framing-gate pins.
