Find Dead Code

Identify dead code in a codebase. Core rule: code only used in tests is still dead code. Only production usage counts.

In an incomplete or abandoned implementation, a declared-but-unused symbol may be intended-but-not-yet-used. When git history shows it was added as a deliberate part of an unfinished stack, recommend investigate rather than delete.

Step 1: Detect Languages, Scope & Test Boundaries

Determine the project structure:

Check for config files: package.json, tsconfig.json, pyproject.toml, setup.py, Package.swift, .xcodeproj, Cargo.toml, go.mod, pom.xml, build.gradle
Glob for source files: **/*.ts, **/*.py, **/*.swift, **/*.go, **/*.rs, **/*.java
Identify source roots — where production code lives (e.g., src/, lib/, Sources/)
Partition the codebase into analysis units by top-level source directories (e.g., src/auth/, src/api/, src/utils/, lib/models/). Each directory becomes one subagent's scope in Step 3.

If the user specified a scope, restrict analysis to that scope.

Test File Patterns

Establish which files are test files. Code referenced ONLY from these locations is dead.

Language	Test file patterns
TS/JS	`.test.{ts,tsx,js,jsx}`, `.spec.{ts,tsx,js,jsx}`, `__tests__/`, `__mocks__/`, `*.stories.{ts,tsx,js,jsx}`
Python	`test_.py`, `_test.py`, `tests/`, `test/`, `conftest.py`
Swift	`Tests.swift`, `Test.swift`, `Tests/*`, `UITests.swift`, `XCTestCase` subclasses
Go	`_test.go`, `testdata/*`
Rust	`tests/`, `benches/`, `#[cfg(test)]` modules (inline test modules within source files)
Java/Kotlin	`src/test/*`, `Test.java`, `Tests.java`, `Spec.java`, `*Test.kt`
General	`fixtures/`, `__fixtures__/`, `mocks/`, `testutils/`, `testhelpers/`, `spec/`

Also exclude: test runner configs (jest.config.*, vitest.config.*, pytest.ini), storybook files, benchmark files.

Step 2: Quick Wins — CLI Tools (Optional)

If a CLI tool is installed, run it as a fast first pass for zero-reference dead code.

Language	Tool	Check	Run
TS/JS	`knip`	`npx knip --version`	`npx knip --no-exit-code`
Python	`vulture`	`vulture --version`	`vulture <src_dirs> --min-confidence 80`
Swift	`periphery`	`which periphery`	`periphery scan --skip-build`
Go	`deadcode`	`which deadcode`	`deadcode ./...`
Rust	compiler warnings	—	`cargo build 2>&1 \| grep "dead_code"`

Important limitation: CLI tools count test imports as real usage. They cannot detect code that is only used in tests. They only find symbols with literally zero references anywhere. Step 3 is required for test-only detection.

If no CLI tool is installed, skip to Step 3. Do not ask the user to install anything.

Step 3: Test-Only Analysis — Parallel Subagents (Core)

Before dispatching, read the project's test configuration and CI workflow to identify any test tier that resets a shared external resource between tests, such as a database, a fixed port, or a cache. Such tiers have no cross-process interlock, so subagents running them concurrently wipe each other's state and return failures that look like real defects. Name any such tier to every subagent as off-limits.

This is the primary analysis. Emit one Agent tool call per top-level source directory from Step 1, all in one assistant message. Each Agent call uses model: "opus" and no name. Wait for every agent to report before continuing. Do not begin the next step on a partial set, and do not relaunch an agent that has not yet reported. Cap at 8 per the Rules section. State the count explicitly when emitting the calls. Each subagent's prompt directs it to treat the shared working tree and its git index as read-only — any empirical check runs in an isolated git worktree created under $TMPDIR and discarded afterward. HEAD stays where it is: read other refs with git show <ref>:<path> rather than git checkout or git switch. Give that worktree its own dependency install rather than reaching the shared tree's install by any route: removing a worktree deletes through symlinks, and a redirected suite writes into the shared install. When its own install is not possible, the check is left unrun and reported as such. Afterward the subagent verifies that git worktree list no longer shows the worktree, that git status --short is clean, that HEAD is still on the branch it started on, and that the shared tree's dependency directory still resolves (a destroyed install leaves git status clean, since it is gitignored). Damage the subagent cannot repair is reported with the exact repair command in place of findings.

Subagent Strategy

Each subagent receives:

Its assigned directory to scan for exported symbols
The test file patterns from Step 1
The full project root path so it can grep across the entire codebase

Subagent Task

Each subagent performs these steps on its assigned directory:

a) Find exported/public symbols:

Language	Exported symbol patterns
TS/JS	`export function`, `export const`, `export let`, `export var`, `export class`, `export interface`, `export type`, `export enum`, `export default`, `module.exports`
Python	Top-level `def` and `class` in non-`_`-prefixed modules, module-level constants (`FOO = ...`), symbols in `__all__`, public functions (no `_` prefix)
Swift	`public func`, `public var`, `public let`, `public class`, `public struct`, `public enum`, `public protocol`, `open class`, `open func`, `open var`
Go	Capitalized identifiers: `func FooBar`, `type FooBar struct`, `var FooBar`, `const FooBar` (Go uses capitalization for public visibility)
Rust	`pub fn`, `pub struct`, `pub enum`, `pub trait`, `pub const`, `pub static`, `pub type`, `pub mod`
Java/Kotlin	`public class`, `public static`, `public void`, `public` fields, `val`/`var` properties, `fun` (top-level), `@Bean`, `@Component`, `@Service` annotated classes

b) For each symbol, grep across the entire codebase for references, excluding:

The definition file itself
Generated/vendored directories (node_modules/, dist/, build/, vendor/, __pycache__/, .tox/, .build/, DerivedData/, target/)

c) Classify each reference as test or production based on the test file patterns.

CRITICAL — same-module references count as production usage. A symbol called by another production file within the same module/package is alive. Do not report symbols as "dead" when they have zero external callers but are used internally. Only report symbols with zero production references from any file. "Unnecessarily public" (could be internal/unexported) is a visibility issue, not dead code — do not include it.

d) Report structured results for each symbol:

Symbol name, type (function/class/const/etc.), definition file and line range
Number of production references (with file paths) — including same-module references
Number of test references (with file paths)
Classification: dead (zero prod refs anywhere), test-only (only test refs), alive (has prod refs)

Merging Results

After all subagents complete, collect and merge their results. Deduplicate any symbols that appear in multiple reports (e.g., re-exports).

Step 4: Filter, Classify & Evaluate

Apply these filters to the merged results from Steps 2 and 3:

Framework entry points: Skip symbols used by convention — React components in barrel files, Django views in URL configs, Go init() and main() functions, Go interface implementations, Rust main(), Rust trait implementations, #[derive(...)] generated code, CLI handlers registered in main, magic/lifecycle methods (__init__, __repr__), serialization methods (to_json, from_dict), interface/protocol implementations
Re-export chains: Trace barrel files (index.ts, __init__.py) before declaring a symbol dead. A symbol re-exported through a barrel may have indirect consumers.
Dynamic usage: Flag symbols that might be used via reflection (getattr, importlib, reflect package in Go, proc_macro in Rust), string-based lookups, or decorator/attribute registration as "likely dead" rather than "definite"
Cross-package references: In monorepos, verify a symbol isn't imported by a sibling package before declaring it dead
Design docs / specs / roadmaps: If the project has spec files, roadmaps, or TODO files (e.g., .turbo/plans/, ROADMAP.md, TODO.md), cross-reference test-only findings against them. Test-only APIs may be planned features awaiting integration — flag as investigate rather than delete. When the only reference is a plan whose frontmatter status: is done, still flag investigate, noting that the plan claims the work shipped: either the status is wrong, or the integration landed and later regressed

Classify each finding:

Definite dead: zero references outside its definition file
Test-only dead: references exist, but ALL are in test files
Likely dead: uncertain due to dynamic usage, framework conventions, or complex re-export chains

Evaluate Findings

Run the /evaluate-findings skill on the classified results to verify each finding against the actual code and weed out false positives. Read the full definition file for each finding — not just the flagged symbol. The surrounding code may reveal that the feature is already implemented differently (e.g., a public ping() method may be test-only while a private keepalive loop in handleConnect() does the real work).

Proceed with the evaluation results in the next section.

For each surviving finding, assign a recommendation:

Signal	Recommendation
No tests, no production usage	delete
Has tests but no production usage, and no spec/roadmap reference	delete (method + test assertions)
Has tests but no production usage, referenced in spec/roadmap/TODO	investigate (planned feature, not dead)
Partially wired up, unclear intent, or needs domain context	investigate

For findings marked investigate, run the /investigate skill to determine whether the code is a planned feature, an unwired integration, or truly dead.

Common Dead Code Patterns

Watch for these high-yield patterns that tools and simple grep often miss:

Test-only state accessors: Public properties/methods that expose internal state solely for test assertions (e.g., isEnabled, count, currentItems). The module's production consumers use behavior (events, callbacks, side effects) — only tests peek at the internal state. When removing these, the corresponding test assertions must also be removed or rewritten to use behavior-based verification.
Unused data model fields: Properties on serializable types (Codable structs, dataclasses, POJOs) that are decoded but never read by any production code. When removing a field from a serializable type, also update all data files that encode it (JSON, YAML, XML, database schemas, migration files).
Vestigial enum cases: Enum cases defined but never constructed or matched against in production code.
Orphaned convenience methods: Public wrappers that call through to another public method with slightly different parameters, where all callers use the underlying method directly.

# Find Dead Code

Identify dead code in a codebase. **Core rule: code only used in tests is still dead code.** Only production usage counts.

In an incomplete or abandoned implementation, a declared-but-unused symbol may be intended-but-not-yet-used. When git history shows it was added as a deliberate part of an unfinished stack, recommend **investigate** rather than **delete**.

1. Check for config files: `package.json`, `tsconfig.json`, `pyproject.toml`, `setup.py`, `Package.swift`, `.xcodeproj`, `Cargo.toml`, `go.mod`, `pom.xml`, `build.gradle`
2. Glob for source files: `**/*.ts`, `**/*.py`, `**/*.swift`, `**/*.go`, `**/*.rs`, `**/*.java`
3. Identify source roots — where production code lives (e.g., `src/`, `lib/`, `Sources/`)

If the user specified a scope, restrict analysis to that scope.

### Test File Patterns

Establish which files are test files. Code referenced ONLY from these locations is dead.

| Language | Test file patterns |
|----------|-------------------|
| TS/JS | `*.test.{ts,tsx,js,jsx}`, `*.spec.{ts,tsx,js,jsx}`, `__tests__/**`, `__mocks__/**`, `*.stories.{ts,tsx,js,jsx}` |

Also exclude: test runner configs (`jest.config.*`, `vitest.config.*`, `pytest.ini`), storybook files, benchmark files.

## Step 2: Quick Wins — CLI Tools (Optional)

If a CLI tool is installed, run it as a fast first pass for **zero-reference** dead code.

| Language | Tool | Check | Run |
|----------|------|-------|-----|
| TS/JS | `knip` | `npx knip --version` | `npx knip --no-exit-code` |
| Python | `vulture` | `vulture --version` | `vulture <src_dirs> --min-confidence 80` |
| Swift | `periphery` | `which periphery` | `periphery scan --skip-build` |
| Go | `deadcode` | `which deadcode` | `deadcode ./...` |
| Rust | compiler warnings | — | `cargo build 2>&1 \| grep "dead_code"` |

**Important limitation:** CLI tools count test imports as real usage. They **cannot** detect code that is only used in tests. They only find symbols with literally zero references anywhere. Step 3 is required for test-only detection.
