code-simplify

A command that simplifies one source file or directory using readability rules while keeping the existing tests passing.

In plain words
What is it for?
Use it on files under the specified source directory, either to apply the simplification or to preview the proposed edits.
Why use it?
It targets hard-to-read constructs such as nested conditional expressions, unclear streams, one-use helpers, and methods with option flags without changing behavior.

Made for: Claude Code.

Per session 23 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 539 The whole file, excluding the scripts and references it only reads on demand.

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

code-simplify 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.

What it actually says

/code-simplify

Phase: 6 (meta) — clarity sweep Owning agent: .claude/agents/spring-code-reviewer.md Skills used: clarity-over-cleverness, tdd-red-green-refactor

Purpose

Apply the clarity-over-cleverness rules to a single file or a directory while keeping tests green. This is the same pass /build's simplify phase performs, but on demand.

Inputs

  • <path> (positional). A file under src/main/** or a directory.
  • Optional --dry-run to print proposed edits without writing.

Reads

  • <path> (the target file/directory).
  • .claude/skills/clarity-over-cleverness/SKILL.md (authoritative checklist).

Writes

  • The targeted files (in place).
  • A diff summary appended to .specs/<feature-id>/05-implementation-log.md under a ### simplify-pass block, or to a fresh clarity-pass-<date>.md if no active feature.

Process

  1. Refuse if mvn test is not green right now (run it first; abort on failure).
  2. For each file in scope, apply the 7 rewrite targets in order:
    1. Untangle nested ternaries → if/else.
    2. Streams only when clearer than a loop; otherwise loop.
    3. Inline once-used helpers.
    4. Kill option flags (split into two methods).
    5. Name domain concepts (no data, info, manager, helper, util).
    6. Remove premature abstraction (interface with one impl, factory with one product).
    7. Prefer early returns over deep nesting.
  3. Re-run mvn test after each file. If anything goes red, revert that file's edits and record it as a Skipped item.
  4. Emit a summary: files touched, rewrites applied per category, tests run, regressions encountered.

Refuse if

  • Tests are not green at start.
  • The path is under src/test/** (test clarity is governed by /test, not this command).

Done when

All in-scope files are either simplified or explicitly skipped, and tests are green.

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.
