What it does
Structural Refactor is an agent skill from nklisch/claude-code-modes. Project structural organization rules for Bun/TypeScript CLI. Proactively scans for organizational issues and produces a prioritized plan. Defines file, folder, and module structure preferences.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/centralized-types.md`, `references/file-size-limit.md` and `references/flat-by-default.md`).
It sits in Development, covering Refactoring. It works with TypeScript. The repository describes itself as: CLI launcher for Claude Code with behaviorally-tuned system prompts — control agency, quality, and scope instead of fighting the defaults. The licence is MIT.
When your agent uses it
- Tasks that involve Refactoring
Example prompts
- “/structural-refactor”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash, Agent, Write
What it can do on your machine
Read from SKILL.md and the folder at commit 4dbbb28. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepBashAgentWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Structural Refactor loads about 526 tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 193 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Glob, Grep, Bash, Agent, Write
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Structural Refactor
Scan the codebase for organizational issues based on these structural rules. Each rule has a reference file with rationale, examples, and exceptions.
Rules
| Rule | Summary (one line) | Reference |
|---|---|---|
| Flat by Default | Keep src/ flat; group into subdirectories only when 3+ files share a concern | details |
| Soft 300-Line Limit | Implementation files should stay under 300 lines; split when single-domain logic exceeds it | details |
| Test Co-location | Unit tests next to source (file.test.ts); integration/e2e tests also in src/ | details |
| Centralized Types | All domain types/interfaces/enums in types.ts; no local type definitions | details |
| No Barrel Exports | No index.ts re-export files; always import directly from the source module | details |
| Prompt Domain Organization | Prompts organized by domain concept (axis/modifier), not by implementation | details |
| kebab-case Files | All source files use kebab-case; test files use {source}.test.ts suffix | details |
Output
Write the refactoring plan to docs/structural-refactor-plan.md.
The document should be a prioritized refactoring plan with these sections:
High Value
Implement-ready entries with file paths, current layout, target layout, and acceptance criteria.
Worth Considering
Valid reorganizations with moderate impact. Brief entries with paths and rationale.
Not Worth It
Code that technically violates a rule but should NOT be reorganized, with explanation why.
