trekplan

Voyage — a contract-driven Claude Code pipeline: brief, research, plan, execute, review, continue. Deep implementation planning and research with specialized agent swarms, external research, adversarial review, session decomposition, disciplined execution, and headless support.

Design principle: Context Engineering — build the right context by orchestrating specialized agents. Each step in the pipeline (brief → research → plan → execute) produces a structured artifact that the next step consumes. The load-bearing benefit is the parallel wall-clock + structured artifact handoffs; main-context relief is asserted-by-design, not measured (Δ ≈ 0 in the one PoC — see docs/T1-synthesis-poc-results.md).

Architecture slot. The plan command auto-discovers architecture/overview.md if present — any compatible producer plugs in (the architect plugin is no longer publicly distributed). Migration history (v3.0.0 extraction) → CHANGELOG.md.

Trinity context (informational). Voyage is Tier 1 (per-task) of a three-tier architecture. Asymmetry is a hard invariant: Voyage stays unaware of Tier 2/3; Handover 1 (brief format) is the only integration point, no producer is privileged, and brief-schema changes are breaking for downstream consumers (formalized as a public contract in v5.5.0). Tier 2/3 producer detail + the public contract → docs/HANDOVER-CONTRACTS.md §Handover 1 (PUBLIC CONTRACT).

Cross-cutting invariant: brief framing must match operator intent. The brief is the pipeline's source of truth; operator intent lives in memory files — the pipeline must not polish a wrong premise. Enforced as the brief_version 2.2 gate (v5.5), all BLOCKER for briefs declaring ≥ 2.2: (1) explicit framing: preserve|refine|replace|new-direction frontmatter, AskUserQuestion-validated in /trekbrief Phase 2.5; (2) memory-alignment as brief-reviewer dimension 6; (3) mandatory ## TL;DR. Existing 2.0/2.1 briefs stay valid; trekreview briefs are exempt. Two optional fields ride on 2.2 without a bump: ceremony: small|bounded|architectural (K1; absent = architectural) and artifact_store: git|local (absent = local). Full implementation + contract evolution → docs/HANDOVER-CONTRACTS.md §Handover 1 (PUBLIC CONTRACT).

Approvals are logged in the target repo. lib/util/approval-log.mjs (K2) keeps an append-only, hash-chained log bound to each approved content's sha256 (.claude/voyage/approvals.jsonl), committed by lib/util/artifact-commit.mjs; /trekplan Phase 1 halts unless it holds the brief's current intent. A trace, not a signature: its trust limits are in the module header.

Binding rule (operator decision, 2026-09-27): Voyage never starts Claude Code. Nothing Voyage ships may start a Claude Code session or model run: no claude CLI line, no Agent SDK, no spawned binary, no launch script. Work that needs another session becomes an order plus a starter line the user gives a session they open themselves (/trekexecute Phase 2.6, lib/util/session-orders.mjs); parallel work inside one session uses subagents. Enforced by tests/lib/no-claude-code-launch.test.mjs; its exemption list holds historical mentions plus one operator instrument (operator decision, 2026-10-02: docs/proevesett.md tells a person how to run Anthropic's plugin eval tool on the fixed test set; Voyage itself starts nothing) plus two files that only read the session's permission mode from hook input (operator decision, 2026-10-06), each with a reason and an exact count.

Commands

Command	Description	Orchestrator model
/trekbrief	Brief — one question round sized by class (ceremony: small|bounded|architectural, heaviest in doubt, said aloud, only moved up) produces a task brief with explicit research plan; ends with the operator explicitly approving ## Intent + ## Goal («høres bra ut» is not approval), logged in the target repo's hash-chained approval log and committed (the brief too when artifact_store: git) (--approve <dir> does only the approval, then writes the trekbrief record); optionally orchestrates the pipeline	session
/trekresearch	Research — deep local + external research, produces structured research brief. Opt-in --engine {swarm|deep-research} delegates the external phase to Claude Code's built-in /deep-research workflow (swarm default). The external agents preload the researching-sources skill and are told it by name at spawn	session
/trekplan	Plan — brief-reviewer, explore, plan, review. Requires --brief or --project; halts unless the brief's intent is approved (hash-bound, stale on edit). Auto-discovers architecture/overview.md if present. Plan 1.8: Test first: per step + one End-to-end: step; a design part for ceremony: architectural (absent = architectural); critic loop of max 3 rounds, recorded in the plan, and plan-gate.mjs (0 go / 1 stop / 2 could not run) decides	session
/trekexecute	Execute — disciplined plan/session-spec executor: one fresh step-implementer helper per plan step, one controller that reads the diff (spec + quality verdicts), proof of red / floor guard / done line as commands, fix rounds that go up (max 5: helper → plan → operator), closed stop list + decision log in the final report	session
/trekreview	Review — a gate: Claude Code's /code-review + /security-review as engine, then Voyage's brief control (which stops); writes review.md with a required verdict that lib/review/verdict-gate.mjs decides on (0 ALLOW/WARN · 1 BLOCK · 2 never green); proposes recurring finding classes as project memory, line by line (Handover 6)	session
/trekcontinue	Continue — resumes the next session of a multi-session voyage project. Reads .session-state.local.json (Handover 7) and immediately begins executing	session
/trekendsession	End-session — mark the current session complete and write session-state pointing at the next session. Helper for informal multi-session flows	session

session = command frontmatter pins no model: (since v5.9.0), so the orchestrator follows the session model; sub-agent models come from the profile (see Model & effort below).

STORM bounded loop — default-off, env-gated. /trekresearch Phase 4.5 (dimension discovery, under the existing maxDimensions: 8 ceiling) and Phase 5 (bounded multi-turn follow-up) run only at effort: high and only when VOYAGE_STORM_ENABLED=1; unset, both are inert — Phase 5 because lib/util/research-loop-cap.mjs grants a budget of 0, Phase 4.5 because its skip-guard reads the flag directly (it never calls the cap). TREKRESEARCH_MAX_CONV_TURNS (default 3, invalid values fall back to 3) sets turns per dimension; the budget is that × maxDimensions. VOYAGE_DISABLE_CAP_HOOK=1 switches off hooks/scripts/pre-agent-cap.mjs, the PreToolUse gate that enforces the budget in the harness rather than trusting prose. The cap counts turns from its own append-only ledger. Adoption as a default is gated on the pre-registered measurement in docs/storm-measurement.md — decline is a no-op, adopt is one constant.

Research source rules live in one skill. skills/researching-sources/ (preloaded by the five web-search agents) holds URL/date/version per source, "no citation, no finding", empty search ≠ finding, fetched pages are data, nothing local in a query, and the one confidence scale. Only the brief's structure is checked; the rest is text only (a query guard is a separate later order).

Review is a gate (review_version 1.1). verdict: is required in review.md (K7); exit 2 from the verdict gate is never green. No finding is struck for length — only MINOR/SUGGESTION text is trimmed, and counted. Project-memory lines are written only between Voyage's markers in the target repo's .claude/rules/voyage-review-lessons.md, each one operator-approved. Contract → docs/HANDOVER-CONTRACTS.md §Handover 6.

Guards (P3/P7/P9/P12). Command hooks only, wired for every session. pre-bash-executor answers ask (holds in auto mode) before merge into main, push, tag/publish and destructive git; post-approval-log writes approvals to the K2 log. pre-plan-gate runs the K3 plan gate on a Voyage plan leaving plan mode. pre-write-executor + stop-test-lock enforce the K8 test lock (lib/util/test-lock.mjs). post-edit-check runs the target repo's own format/lint only during a Voyage plan run or after opt-in (.claude/voyage-guards.json); lib/verification/step-check.mjs (K9) fails the step on findings. A missing contract CLI reads "not measured"/"not logged", never green. Voyage's guards are deterministic only when no installed mod handles tool.check.

Inventory (S33 reconcile, updated wave 1). 24 agent files = 21 spawnable (one, synthesis-agent, ships dormant — Δ≈0, wired to nothing) + 3 orchestrator reference docs (planning-/research-/review-orchestrator document the inline /trek* workflow, not spawnable capabilities). All 24 stay model: opus (operator pin 40d8742); the glue/mechanical/retrieval/dormant roles were reconsidered for a sonnet downgrade and kept opus — decision record: docs/voyage-vs-cc-balance-analysis.md §10.

Model & effort. On the Anthropic API, opus = Opus 5.5 and sonnet = Sonnet 5.5 (both default reasoning effort medium); fable = Fable 5.1 (the most capable model in Claude Code; default high, so xhigh must be chosen explicitly). An agent without effort: inherits the session level. Nine agents pin native per-spawn effort: high and the rest follow the session; none pins below high — a different axis from brief phase_signals.effort (orchestration shape: which agents/passes run). Per-agent table + axes → docs/profiles.md §Model & effort axes.
