A guided process for converting an existing Java repository into Trabuco's multi-module Maven project structure. Maven is a build tool for Java, and a multi-module project splits related parts into separate modules.

It is for moving an existing Java or other JVM codebase into Trabuco conventions and module layout. It does not migrate Python, Go or JavaScript/TypeScript repositories, and leaves frontend code in a monorepo untouched.

It breaks a large migration into dependency-aware phases while keeping the old continuous-integration checks working at phase boundaries. Approval gates and Git tags provide checkpoints for reviewing or rolling back each phase.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add arianlopezc/Trabuco --skill migrate

Clone the repo

git clone --depth 1 https://github.com/arianlopezc/Trabuco

Made for: Claude Code.

Or install trabuco, the plugin that ships this one along with the rest of its 10 skills, 24 agents, 2 hooks, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00084	$0.00921
Opus 5	$0.00042	$0.00461
Sonnet 5	$0.00017	$0.00184

Security

Grade A, and why

migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Migrate an existing Java project into a Trabuco-shaped project

This skill drives the 14-phase migration. It is the user-facing entry point. The actual reasoning is delegated to the trabuco-migration-orchestrator subagent, which coordinates 13 specialized subagents (one per migration phase).

When to invoke

User says "migrate this project to Trabuco" / "convert this codebase to Trabuco" / "trabuco migrate " / similar.
User has an existing JVM repository they want transformed into Trabuco's multi-module Maven structure with conventions intact.

When NOT to invoke

User wants a brand-new project → use /trabuco:new-project instead.
User has a Trabuco project already and wants to extend it → use /trabuco:add-module or /trabuco:extend.
Repository is non-JVM (Python, Go, JS/TS) → tell the user this is out of scope; Trabuco only migrates JVM code. Frontend in a monorepo is left untouched.

Flow

Hand off to the orchestrator subagent. Invoke trabuco-migration-orchestrator with the user's argument (the repo path) plus their stated goals. The orchestrator:
- Runs preflight (clean working tree, on a branch, repo has commits).
- Runs migrate_assess to scan the source and produce .trabuco-migration/assessment.json (the no-out-of-scope contract).
- Walks the user through 14 phases, presenting diffs and gates at each.
- Records user decisions via migrate_decision.
- Rolls back via migrate_rollback if the user rejects a phase.
Do NOT do the work yourself. This skill is a router. The orchestrator subagent owns the migration. Your only job here is to invoke the right subagent and surface its summary.

Rules for the orchestrator subagent

No out-of-scope. Every change must be grounded in evidence from .trabuco-migration/assessment.json. Specialists that propose unevidenced changes are auto-rejected by the orchestrator's diff-inspection layer.
Dependency-aware phasing. Enforcement mechanisms (Maven Enforcer, Spotless, ArchUnit, Jacoco threshold) are deferred until Phase 12. Skeleton generates a "migration-mode" parent POM with skip flags. Legacy CI must keep working at every phase boundary.
No invented infrastructure. The deployment phase only adapts what the legacy already has. Never adds CI/CD, monitoring, or deployment scaffolding that wasn't there.
Safe over fast. Default gate granularity is per-phase; the user can request --per-aggregate for high-risk phases (Datastore, API).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migrate is a skill published in the GitHub repository arianlopezc/Trabuco (0 stars, last pushed 3mo ago), licensed MIT. It adds 84 tokens to every session and 921 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
