name: vibeloom description: Contract-driven governance for long-lived AI-coded projects. Use when the user wants to bootstrap, import, generate, review, reconcile, or approve artifacts in a project governed by the VibeLoom methodology (modes: vibe, pm, dev, expert). argument-hint: "[init|import|generate|eval|review|reconcile|approve|status] [target]"

VibeLoom

VibeLoom governs long-lived AI-coded projects by generating a tiered contract of specifications (intent-specs → product-specs → system-specs), deriving execution context from it, and generating code from the approved stack. The user retains approval authority; subagents do the scoped work in parallel waves.

When to use this skill

Invoke on any $vibeloom or /vibeloom command, or when the user mentions VibeLoom, contract-driven governance, or asks to run any of the methodology operations (init, import, generate, eval, review, reconcile, approve, status).

Authoritative sources

Always consult these before making decisions:

• vibeloom-methodology.md — WHAT and WHY (entities, tiers, modes, operations, approval model, derivation DAG). If this skill file conflicts with the methodology, the methodology wins.
• vibeloom-implementation.md — HOW (artifact layout, metadata shape, ID schema, runtime loop, subagent dispatch, load sets).

Runtime references (load on demand)

• references/operations.md — per-operation quick reference (purpose, parameters, preconditions, postconditions).
• references/modes.md — per-mode behavior (vibe, pm, dev, expert): tier ownership, auto-advance, public surface.
• references/runtime.md — dispatch mechanics: runtime loop, waves, load sets, late-fetch, validation.
• references/artifacts.md — artifact layout, frontmatter shapes, ID schema, derivation rules.
• references/eval.md — semantic-eval dimensions, finding schema, severity classification (what the agent checks on top of the engine's structural eval).
• references/troubleshooting.md — failure modes and recovery (cache corruption, direct edits, breaking changes, partial wave failure).

Templates

The 17 artifact templates live under assets/:

• intent-specs/: intent.md, vibe-intent.md, defaults.md
• product-specs/: prd.md, usm.md, dm.md
• system-specs/: system.md, vibe-system.md, containers.md, container.md, component.md
• context/: pdr.md, adr.md, bdd.md, root-config.md, container-config.md, component-config.md

Load one template at a time for the artifact being generated.

Engine

The engine/ directory contains the Python package that implements the deterministic substrate described in vibeloom-implementation.md. Zero install, zero dependencies — Python 3.10+ is the only requirement. Invoke the engine via python -m with PYTHONPATH pointing at engine/:

PYTHONPATH=<skill-root>/engine python3 -m vibeloom_engine <command> --repo <target-repo>

<skill-root> is the directory containing this SKILL.md. Available commands:

Engine command	Purpose
python3 -m vibeloom_engine parse --repo <path>	Parse all artifacts; emit JSON inventory
python3 -m vibeloom_engine graph --repo <path>	Build + persist .vibeloom/state/context-graph.json
python3 -m vibeloom_engine eval --repo <path> [--target <tier>]	Run structural eval; non-zero exit on blocking findings
python3 -m vibeloom_engine affected --repo <path> --ids <IDs...>	Compute the affected set from changed item IDs
python3 -m vibeloom_engine staleness --repo <path>	Detect stale artifacts (approved-basis mismatch)
python3 -m vibeloom_engine status --repo <path>	Emit a status snapshot; persist .vibeloom/state/status.json
python3 -m vibeloom_engine detect-edits --repo <path>	Detect direct edits on approved contract artifacts (mtime fast-path, per-item hash confirmation)

All engine commands emit JSON on stdout. The engine makes no semantic judgments — it parses, validates structure, computes the graph, and reports. Semantic judgment and user interaction remain with the skill.

Optional: pip install -e engine puts a shorter vibeloom-engine command on PATH. Not required for skill operation.

Command routing

On any operation invocation, load references/operations.md first for parameters and preconditions, then load the subset of references/ relevant to the operation:

Operation	First load	Then
init, import	operations.md, modes.md	template for intent (init) or reconstruction prompts (import)
generate <target>	operations.md, runtime.md	target-tier templates + graph cache
eval <target>, review <target>	operations.md, runtime.md, eval.md	target artifacts + methodology eval checks
reconcile <target>	operations.md, runtime.md, eval.md	downstream artifacts + graph
approve <target>	operations.md, modes.md, eval.md	target artifacts
status	artifacts.md	graph cache + status snapshot

Getting started

If the repo has no VibeLoom governance yet, the user typically starts with init --mode <vibe|pm|dev|expert> (new project) or import --mode <mode> (existing codebase). Consult references/modes.md to help the user pick a mode.

Guardrails

• Never bypass an approval gate. When a contract tier is a user stop in the current mode, halt and surface findings rather than advancing.
• Treat the methodology as authoritative. If this file or a reference disagrees with the methodology, follow the methodology and flag the drift.
• Do not invent entity types, ID prefixes, or derivation edges. The valid set is defined by the methodology's Derivation DAG.
• Subagents receive scoped load sets only. They never load the skill or the methodology docs.
• Late-fetch is bounded: one re-invocation per task; exceed means a finding and task exit.
• reconcile is always user-initiated. Never auto-invoke it.

Response shape

Keep responses tight. For operations that pause for user input, use a four-section structure:

1. Scope — what tier/scope this operation touched
2. Decision — what the skill did or is asking the user to decide
3. Affected — item IDs, artifacts, and scopes changed or surfaced
4. Next — the suggested next command
