overengineering

overengineering is a plugin for Claude Code from melodic-software/claude-code-plugins. Its manifest loads nothing; the 1 skill it bundles cost 99 tokens per session together, scanned A, original, MIT.

A read-only audit of the rules and checks that enforce how a project is built and changed. It examines agent instructions, repository hooks, continuous integration checks, branch protections, and external integrations.

In plain words
What is it for?
Use it to review build and workflow controls, identify redundant mechanisms, and create findings for a simpler setup.
Why use it?
It identifies enforcement that costs more to maintain than the value it provides. It keeps security-related retirement decisions for human review.

Security

Grade A, and why

overengineering 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 14d 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.

What it actually says

{
  "$schema": "https://json.schemastore.org/claude-code-plugin-manifest.json",
  "name": "overengineering",
  "version": "0.4.21",
  "description": "Evidence-earned-keep audit of an existing enforcement surface, covering agent hooks and standing instructions, repository and version-control hooks, CI lanes and gate scripts, branch protections, forge apps, and declared external integrations. It treats every incumbent mechanism as a retirement candidate until empirical evidence earns its keep, argues every verdict in cost of carry, caps retirement-direction verdicts on security-class artifacts at FLAG-FOR-HUMAN, and realigns to the simplest adequate solution behind an explicit per-item human gate. The audit is read-only and emits a diffable findings artifact; realignment is a separate, explicitly invoked skill; and a third read-only lane re-runs the audit on whatever cadence the consumer wires and reports only what moved since the last run, above a configurable noise budget. A justification lane applies the same method to whatever single artifact you point at, a decision record, a document, a component, a dependency, or a code construct, asking whether a reason existed for it and whether that reason still holds, and reporting how much evidence each verdict actually rests on.",

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 99 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
