## TL;DR

A class or file declares more functions than detekt's threshold (default 11 per type). Extract a cohesive group of functions into a new class, or raise the threshold in `detekt.yml` if the team agrees the limit is wrong.

## Error

```text
TooManyFunctions: The class OrderProcessor has too many functions (14). (detekt)
```

## Steps

1. Identify the flagged type and its function count from the detekt report. Expected: the class/file and the count over the threshold.
2. Group the functions by responsibility and extract one group into a new class (e.g. `OrderValidator`). Expected: both types are under the threshold.
3. If the class is a legitimate facade, suppress narrowly: `@Suppress("TooManyFunctions")` on the class with a comment. Expected: detekt skips the rule for that class only.
4. Re-run `./gradlew detekt`. Expected: no TooManyFunctions findings.

## When to use

- detekt reports `TooManyFunctions` on a class, file, or object in the PR.
- The count genuinely exceeds the configured threshold.

## When not to use

- ktlint fails on formatting  -  use the ktlint fix instead.
- The flagged unit is generated code; exclude the path in detekt config.

## Tool compatibility

- detekt 1.23+.
- Kotlin 1.8+.

## Variant phrasings

### TooManyFunctions on an object declaration

Same fix: extract to a named class or split the object.

### Threshold too strict for the codebase

Set `threshold: 15` under `TooManyFunctions` in detekt.yml and document the decision.

## Why it happens

TooManyFunctions is a complexity guard: types with many functions usually mix responsibilities and are hard to review. detekt fails the gate to force the split before the code lands.

## Edge cases

- Splitting purely to satisfy the count without real cohesion just moves the problem; group by responsibility.
- Interface delegations count toward the total; prefer composition to shrink the surface.
