# 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 — see `docs/HANDOVER-CONTRACTS.md` §Handover 1 (PUBLIC CONTRACT).

> **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), implementert i S6 som `brief_version 2.2`-gate (v5.5), alle BLOCKER ved brudd for briefer som deklarerer ≥ 2.2:** (1) eksplisitt `framing: preserve|refine|replace|new-direction` i brief-frontmatter, `AskUserQuestion`-validert i `/trekbrief` Phase 2.5 før brief-prosa skrives (ikke-skippbar, også i `--quick`); enum-feil → `BRIEF_INVALID_FRAMING` (alle versjoner), fravær ved ≥ 2.2 → `BRIEF_MISSING_FRAMING`; (2) memory-alignment som dimensjon 6 i `brief-reviewer` — sammenlikner brief-prosa + `framing` mot relevante memory-filer, rapporterer kun eksplisitte motsigelser (degraderer til score 5 N/A uten memory-kontekst), wired til Phase 4e-gate (`memory_alignment.score ≥ 4`); (3) obligatorisk `## TL;DR`-seksjon (≤ 5 linjer, soft-cap → `BRIEF_TLDR_TOO_LONG`) øverst i `brief.md`. Eksisterende 2.0/2.1-briefer forblir gyldige (forward+backward-compat, speiler `phase_signals ≥ 2.1`-presedensen); `trekreview`-briefer er unntatt. **Schema-akse bumpet (2.1→2.2); plugin-versjon-badge + CHANGELOG bumpes ved den koordinerte releasen (S10).** Kontrakt-evolusjon dokumentert i `docs/HANDOVER-CONTRACTS.md` §Handover 1. Den gamle manuelle stopgap-sjekken er dermed retired for ≥ 2.2-briefer.

## 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 |

## Agents

| Agent | Model | Role |
|-------|-------|------|
| planning-orchestrator | opus | Inline reference documentation for the planning pipeline workflow (brief-driven) |

| git-historian | opus | Recent changes, ownership, hot files |
| research-scout | opus | External docs for unfamiliar tech (conditional, planning only) |
| convention-scanner | opus | Coding conventions: naming, style, error handling, test patterns |

| synthesis-agent | opus | Distills Phase-5/7 exploration outputs into a findings digest (NW3 PoC — **dormant**, not wired; delegating Phase 7 alone yields Δ main-context ≈ 0, see `docs/T1-synthesis-poc-results.md`) |
| docs-researcher | opus | Official documentation, RFCs, vendor docs (Tavily, MS Learn) |
| community-researcher | opus | Community experience: issues, blogs, discussions |

| contrarian-researcher | opus | Counter-evidence, overlooked alternatives |
| gemini-bridge | opus | Gemini Deep Research second opinion (conditional) |

> **Model & effort (CC 2.1.154+).** `opus` resolves to **Opus 4.8** (default reasoning effort `high`); `sonnet` to Sonnet 4.6. Select agents carry native `effort:` — retrieval agents (`task-finder`, `git-historian`, `dependency-tracer`, `architecture-mapper`) at `medium`, adversarial-reasoning agents (`plan-critic`, `risk-assessor`, `contrarian-researcher`, `review-coordinator`) at `high`. This native per-spawn **reasoning** effort is a different axis from brief `phase_signals.effort` (orchestration shape — which agents/passes run). See `docs/profiles.md` §Model & effort axes.
