complexity-audit

complexity-audit is a skill for Claude Code from yuri-semenenko/ai-engineering-workspace. It costs 117 tokens per session (565 once invoked), scanned A, original, MIT.

A codebase-wide review for unnecessary complexity, such as premature abstractions, needless layers, wrapper-only modules, and unused configuration. It produces a prioritized report focused on what could be removed.

In plain words
What is it for?
Use it to audit a whole repository or selected subtree and identify deletion or simplification opportunities by subsystem.
Why use it?
It helps find over-engineering that is already spread through the project rather than only reviewing the latest code change.

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.

Security

Grade A, and why

complexity-audit 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.

What it actually says

Complexity Audit

Find accidental complexity that already shipped. This is a standing-codebase scan, not a diff review — use /code-review or /simplify for the current change.

How to run (keep main context lean)

  1. Map the tree first. If a path argument was given, scope the whole audit to that subtree; otherwise take the whole repo. Identify top-level subsystems / packages from the layout (workspaces, src/ domains, services).
  2. Fan out, do not grep inline. Per the persona's session-hygiene rule, dispatch Explore subagents — one per subsystem — each tasked to surface over-engineering only. Each returns a compact findings list, not file dumps. This keeps large intermediate output out of the main conversation.
  3. Dedup and prioritize the merged findings before reporting.

What counts as over-engineering (the persona's anti-patterns)

  • Premature abstraction / speculative generality (interfaces with one implementation, config for things that never vary).
  • Pattern-heavy designs where a function would do (factories, managers, base classes added "for the future").
  • Needless layering / indirection with no payoff; wrapper modules that only re-export.
  • Framework-driven architecture: structure dictated by a framework, not the domain.
  • Dead code, unused flags, config that no longer changes behavior.
  • Tight coupling and leaky abstractions hidden behind "clean" names.

Do not flag: intentional // TRADEOFF(...) annotations (those are tracked by /debt-ledger), validation, error handling, security, or tested invariants.

Output

Prioritized report, most-impactful first. For each finding:

Severity Location (file:line) What's over-built Why it doesn't pay for itself Proposed simplification Risk of removing

Severity = blast radius × how speculative it is. End with a short "highest-leverage deletions" shortlist. State assumptions explicitly. No marketing prose.

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.
