# 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.

> **v3.0.0 — architect step extracted from this plugin.** The plan command still auto-discovers `architecture/overview.md` if present, so any compatible producer (architect plugin no longer publicly distributed; the architecture/overview.md slot remains available for any compatible producer) plugs into the same slot. See [CHANGELOG.md](CHANGELOG.md) for migration history.

> **Trinity context (2026-05-13, informational).** Voyage is Tier 1 (per-task) of a three-tier architecture in active design under the author's private marketplace: Tier 2 `app-creator` (per-app — "what does the app need, what's the next brief?") produces briefs Voyage consumes; Tier 3 `app-factory` (per-portfolio — "which app needs me now?") aggregates state across multiple app-creator instances. Both are pre-implementation and will ship to Forgejo when ready. **Asymmetry is a hard invariant:** Voyage stays unaware of Tier 2/3. Handover 1 (brief format) is the only integration point — any compatible producer can feed Voyage, app-creator is not privileged. Brief-schema changes are therefore breaking changes for downstream consumers, formalized as a public contract in v5.4.

> **Cross-cutting invariant: brief framing must match operator intent (2026-05-15).** Etablert etter residiv. Briefen er pipelinens source of truth; operatørens intent lever i hodet + i memory-filer (`feedback_*`, `project_*`); pipelinen tvinger ikke alignment. Høyere reasoning-kraft polerer feil premiss istedenfor å utfordre det. **Tre lag av forsvar (input-siden), alle BLOCKER ved brudd når v5.5 shipper:** (1) eksplisitt `framing: preserve|refine|replace|new-direction` i brief-frontmatter, `AskUserQuestion`-validert før brief-prosa skrives; (2) memory-alignment check som ny dimensjon i `brief-reviewer` — sammenlikner brief-prosa mot relevante memory-filer og rapporterer eksplisitte motsigelser; (3) obligatorisk `## TL;DR`-seksjon (≤ 5 linjer) øverst i `brief.md`. Implementeres i v5.5 — se [ROADMAP.md](ROADMAP.md). Inntil shipping: operatør må manuelt sjekke at briefens framingord ikke motsier intent, særlig etter avvist iterasjon hvor "delta fra forrige" er en farlig default-ankring.

## Commands

| Command | Description | Model |
|---------|-------------|-------|
| `/trekbrief` | Brief — interactive interview produces a task brief with explicit research plan; optionally orchestrates the pipeline | opus |
| `/trekresearch` | Research — deep local + external research, produces structured research brief | opus |
| `/trekplan` | Plan — brief-reviewer, explore, plan, review. Requires `--brief` or `--project`. Auto-discovers `architecture/overview.md` if present | opus |
| `/trekexecute` | Execute — disciplined plan/session-spec executor with failure recovery | opus |
| `/trekreview` | Review — independent post-hoc review of delivered code against the brief. Produces `review.md` with severity-tagged findings (Handover 6) | opus |
| `/trekcontinue` | Continue — resumes the next session of a multi-session voyage project. Reads `.session-state.local.json` (Handover 7) and immediately begins executing | opus |
| `/trekendsession` | End-session — mark the current session complete and write session-state pointing at the next session. Helper for informal multi-session flows | opus |
