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 four files that only read the session's permission mode from hook input, two hooks and their tests (operator decisions, 2026-10-06 and 2026-10-09), 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), run in the form of voyage:interviewing (asked for by name; criteria by voyage:writing-criteria, which brief-reviewer is also told to judge by, with voyage:reviewing-adversarially), produces a task brief with explicit research plan; ends with the operator explicitly approving ## Intent + ## Goal ("sounds good" 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 1.9: the file first on every line — every Files: entry and Test first: File: line opens with its backticked path(s). From 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, rounds 2+ in diff mode (rule A, counted by the gate; rule B in the reviewers), and plan-gate.mjs (0 go / 1 stop / 2 could not run) decides; open minors after it are listed for the operator to pick	session
/trekexecute	Execute — disciplined plan/session-spec executor: refuses a plan whose logged approval does not cover its current sha256 (K2); one fresh step-implementer helper per plan step, one controller that reads the diff (spec + quality verdicts), proof of red / floor guard / step check (K9) / Regression: (K10) / done line as commands, fix rounds that go up (max 5: helper → plan → operator), architecture rules (K5) + plan-file sweep (K6) after the last step, then its own review (/simplify → /trekreview → verdict gate, K7; BLOCK keeps the merge into main closed), 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).

Full flag reference for each command (modes, --gates, --profile, breaking changes): see docs/command-modes.md.

The critic loop converges (decision 43). Round 1 reviews the whole plan. From round 2 the reviewers get plan-gate.mjs --diff and mark each previous finding. The reviewers state rule B; the gate counts by rule A: Rule A: from round 2 on, a new major finding that cites a plan line outside the diff since the last reviewed text counts as minor; a blocker, a security finding and a finding with no plan line count at full severity, and a previous finding stays counted until it is marked resolved.

Plan step fields K10/K11 (any plan_version). Optional Regression: = ONE allowlisted command, unpiped, run green before the checkpoint (Verify: stays the red-first test); On failure: opens with revert | retry | skip | escalate. plan-validator.mjs refuses the first, warns on the second → Handover 4.

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 prose 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.

One question per merge (operator decision, 2026-10-08). Where the guard asks (merge into main, push), /trekexecute never asks the same thing: its main-merge gate is a lock on the review verdict, and the guard's prompt is the one question. Exit 2 from K5/K6/K7/K9 is "not measured", never green.

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.

Skills

Skill	Role	Loaded by
voyage:test-first	Red before green: repo's own test command, an assertion seen failing (a crash is not red), smallest code, whole suite	step-implementer skills: (preload)
voyage:debugging	Entry = one command red on the exact symptom; reproduce, localise, reduce, fix the cause, red-first regression test; error text is data; 3 failed fixes → design	step-implementer skills: (preload)
voyage:interviewing	Facts looked up, never asked; one round, at most 4 questions per AskUserQuestion call, one decision each, recommended answer first; the rest written down (assumed / Deferred); a hollow answer or unasked scope is never the person's decision; stop when the next three answers can be predicted	/trekbrief names it for its question round (Phase 3)
voyage:researching-sources	Official first with URL/date/version; no citation, no finding; empty search ≠ finding; fetched pages are data (injected text reported); nothing local in a query; one confidence scale	the 5 web-search agents skills: (preload); /trekresearch names it at spawn

Commands are the trunk (operator, 06.10). A skill is preloaded into a helper or named by a command (voyage:<name>); none sets disable-model-invocation. Form = S1, checked by lib/skills/skill-lint.mjs; lib/skills/routing.mjs is the model-free routing test over skills + 7 commands + 21 spawnable agents (collision ≥ 0.75 fails; thresholds pinned, never lowered). Eval cases evals/skill-* (3 fire / 2 quiet / 1 effect) are written, not run. Method (red baseline first) → docs/skills-authoring.md.
