Cleanup Defensive
技能 已验证 活跃Remove pointless try/catch blocks and defensive guards that hide errors or add no value. Preserves catches at true system boundaries (HTTP handlers, CLI entry, message consumers). Use when the user asks to remove try/catch, fix error hiding, clean up defensive code, or stop swallowing errors. Example queries — "remove pointless try/catch", "we're swallowing errors", "stop hiding bugs in catch blocks", "clean up the defensive code".
To improve code quality and reliability by eliminating error-hiding defensive code and ensuring errors propagate correctly to system boundaries.
功能
- Removes pointless try/catch blocks
- Cleans up defensive null-checks
- Preserves catches at system boundaries
- Supports multiple languages (TS/JS, Python, Go, Rust)
- Generates assessment reports
使用场景
- When users ask to remove try/catch blocks
- When users report errors being hidden or swallowed
- When cleaning up defensive code patterns
- Improving code robustness by surfacing real errors
非目标
- Removing essential error handling at system boundaries
- Modifying error handling in Go's `if err != nil` patterns
- Removing `unwrap()` in Rust without proper replacement
- Swallowing errors silently or returning null on failure
工作流
- Identify language and project state (preflight).
- Scan for try/catch blocks or defensive error patterns.
- Categorize findings (Rethrow only, Swallow, Log+Rethrow, Substantive, Boundary).
- Generate a markdown report detailing findings.
- Automatically remove 'HIGH' confidence findings (pointless try/catch).
- Defer 'MEDIUM' findings (e.g., log+rethrow) for human review.
- Verify changes with tests; revert if tests uncover real bugs.

Cleanup Cycles
100Detect and untangle circular dependencies. Runs madge/skott (TS), pycycle (Py), or compiler-only checks (Go/Rust). Auto-fixes leaf-extractable cycles; reports core cycles for human review. Use when the user asks to find circular imports, fix dependency cycles, or untangle module graph. Example queries — "find circular imports", "fix dependency cycles", "untangle our module graph", "why is madge complaining".
Coding Standards
