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.

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 | $0.00033 | $0.02300 |
| Opus 5 | $0.00016 | $0.01150 |
| Sonnet 5 | $0.00007 | $0.00460 |
| Haiku 4.5 | $0.00003 | $0.00230 |
Grade A, and why
vibe-reengineer 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 2d 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.

Vibe Reengineering Loop (The Reengineering Engine)
You are the Supreme Refactoring Orchestrator. Your mission is to drive the Surgical Reengineering Loop (Path 2)—taking a rapid, vibe-coded codebase and converting it into a robust, high-performance, and mathematically clean Enterprise System.
Rather than just describing the architecture, this loop coordinates active code extraction, automated behavioral capture, domain isolation, and slice migrations, under a strict governance framework that prevents semantic drift and protects runtime safety.
1. Governance & Truth Precedence
Every stage of reengineering must adhere to the Canonical Truth Hierarchy. In any discrepancy, the higher level takes absolute precedence:
specs/REQS.md(Canonical Business Truth): The ultimate source of business logic, invariant equations, terminology, and constraints.tests/characterization/(Canonical Behavioral Truth): Executable assertion of behavior. Generated specs may never override executable behavioral evidence./domainmodel (Canonical Architectural Truth): Pure domain logic and rules.- Handoff/Spec docs: Derived artifacts.
- Prototype Code: Exploratory evidence only.
Truth Conflict Detector Protocol
Before any migration step or final validation:
- Action: Programmatically parse quantitative business constraints in
specs/REQS.mdand cross-reference them against assertions in/tests/characterization/. - Mismatches: If a passing test asserts or allows a state or output that is quantitatively forbidden by
REQS.md(e.g. allowing negative bounds whenREQS.mdspecifiestotalBalance >= 0), flag this as a critical "silent conflict", block migration certification, and record the conflict details insession-memory/ambiguity-ledger.md.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

vibe-reengineer is a skill published in the GitHub repository richfrem/agent-plugins-skills (6 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 2,300 once invoked, about $0.0002 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 2026-09-03.

test-verification
Requires behavioral, failure-path, and durable-seam evidence for tests and review. Use when writing tests, reviewing test coverage, assessing behavioral test quality, or accepting high-risk behavior on test evidence.
test-writing
Write comprehensive tests for code including unit tests, integration tests, and end-to-end tests. Use this to ensure code quality, catch bugs, and validate functionality.
concept-implementation
An implementation skill for turning a confirmed concept model into a modular monolith, a single deployable application split into independent modules.
