What is android-detekt-expert?

A guide for checking Kotlin Android code for logic mistakes, code smells, structural problems, and code debt. Detekt is a Kotlin static-analysis tool that examines code without running it.

Reviewing function complexity, nested code, naming, unused members, unreachable code, equality and hash-code issues, and custom architecture rules in Android projects.

It helps find maintainability problems and possible bugs before they reach users or become harder to fix. It can also support build checks that reject code violating defined rules.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.00796
Opus 5.5	$0.00010	$0.00318
Sonnet 5.5	$0.00005	$0.00159
Haiku 4.5	$0.00003	$0.00080

Security

Grade A, and why

android-detekt-expert 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 2mo 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.

Android Detekt Logic Analysis 🧐🔍

Advanced strategies for detecting hidden logic errors, structural flaws, and code debt in Kotlin Android applications.

⚡ When to Use

Code Smell Hunting: Identifying long functions, deeply nested loops, or excessive cognitive complexity.
Architectural Guardrails: Enforcing rules like "No viewModelScope.launch outside of ViewModels".
Naming Enforcement: Ensuring all interfaces end with Interface (if that's the team policy).
Refactoring Strategy: Identifying the most "complex" files that need simplification first.
CI/CD Quality Gate: Failing a build based on logic violations.

🏗️ Core Categories

1. Complexity

TooManyFunctions: Aim for < 11 functions per class.
LongMethod: Aim for < 20 lines per function.
NestedBlockDepth: Aim for < 4 levels of nesting.

2. Formatting (Logic-Based)

OptionalUnit: Don't return Unit explicitly.
UnusedPrivateMember: Delete unused variables and functions.
RedundantVisibilityModifier: Keep it clean if defaults are sufficient.

3. Potential Bugs

EqualsWithHashCode: Always override both together.
UnreachableCode: Remove code that can't be executed.
UnsafeCallOnNullableType: Avoid using !! operator.

4. Style & Naming

ForbiddenMethodCall: Block usage of certain libraries (e.g., java.util.Date in favor of java.time or kotlinx-datetime).
ForbiddenImport: Prevent importing internal or deprecated classes.

🛠️ Essential Commands

Check Logic Errors

./gradlew detekt

Auto-Correct (Basic)

./gradlew detekt --auto-correct

📜 Configuration (`detekt.yml`)

Use a custom configuration file to override default thresholds:

complexity:
  TooManyFunctions:
    active: true
    thresholdInFiles: 11
    thresholdInClasses: 11
    thresholdInInterfaces: 11
    thresholdInObjects: 11
  LongMethod:
    active: true
    threshold: 20

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.
