What is wicked-garden-engineering?

An engineering guide for reviewing code, checking system design, finding bugs, planning changes, and writing documentation.

Use it for code or diff reviews, architecture checks, debugging, implementation plans, documentation, and mechanical changes across multiple files.

It gives a structured way to assess code and plan work, reducing missed problems and unclear implementation decisions.

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	$0.00285	$0.02430
Opus 5	$0.00143	$0.01215
Sonnet 5	$0.00057	$0.00486
Haiku 4.5	$0.00028	$0.00243

Security

Grade A, and why

wicked-garden-engineering 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Engineering

Senior engineering guidance on code quality, architecture, and implementation. The five actions below run inline (no dispatch); genuinely structural, migration, or API-reference work dispatches to the fork workers listed at the end.

Routing

Ask	Action
Code-level quality review of files or a diff	§ review
Component/system-level architecture review	§ arch
Bug / error / unexpected-behavior diagnosis	§ debug
Implementation plan before writing code	§ plan
Generate or refresh documentation	§ docs
Multi-file mechanical change (add-field/rename/remove)	patch

Review disambiguation: this skill reviews source code. For an AI agent system use agentic review, for a UI use product ux-review, and for a binding go/no-go verdict use archetype review (see docs/domains.md → "review appears in three domains"). arch is component/system-level review; review is code-level; greenfield design is the architecture module.

review — senior-engineer code review

Parse scope (path or git-diff target), --focus, --persona, and --scenarios.
Read("${CLAUDE_PLUGIN_ROOT}/skills/engineering/refs/review.md") — R1–R6 Bulletproof Coding Standards, T1–T6 Bulletproof Testing Standards, agent overstepping checklist, focus lane definitions, persona routing instructions, wicked-scenarios format, and output template.
Persona branch (only if --persona <name> present): resolve the persona via scripts/persona/registry.py --get {name} --json. If found, apply the review through that persona's frame. If not found, warn and fall through.
Read the target file(s) / diff. Apply R1–R6 to all code; add T1–T6 when --focus tests or reviewing test files. If --focus given, deepen that lane. Flag agent overstepping (scope creep, commented-out code, over-engineering) with file:line citations.
Emit the standard Engineering Review output (Strengths, Issues table with rule + location, Architecture Notes, Maintainability Concerns, Agent Overstepping, Recommendations). If --scenarios, append wicked-scenarios blocks for each Critical/High finding.

What ships with it

Changes

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.

wicked-garden-engineering is a skill published in the GitHub repository mikeparcewski/wicked-garden (9 stars, last pushed today), licensed MIT. It adds 285 tokens to every session and 2,430 once invoked, about $0.0014 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.

Code review Debugging

adversarial-reviewer

Adversarial code review that assumes bugs exist and hunts for them. Use when asked to review code, find bugs, audit for correctness, stress-test a PR, or when someone says "tear this apart" or "what's wrong with this". Give no benefit of the doubt — every line is guilty until proven innocent.

issue

Use when starting a chain from a GitHub issue — turning an issue URL or number into a triaged, planned, dispatched, and reviewed pull request. Classifies the thread (bug → root-cause discipline, feature → plan chain, question → drafted reply), synthesizes a spec from the issue's own acceptance criteria, then runs the…
