CodingTokenStats

All Implemented Interfaces:
```
public final class CodingTokenStats

                    
```
Per-method token statistics accumulator for the coding domain.
Records, for every tool call: input (serialized arguments) and output (result string) size in chars and estimated tokens, call/error counts, duration, and max sizes. Thread-safe; fixed memory footprint (one entry per distinct method name).
Consumed by coding.tokenStats so the agent and developers can audit which coding tools consume the most context window.

Modifier and Type	Method	Description
`final Boolean`	`isEmpty()`	True when nothing has been recorded yet.
`final Unit`	`record(String method, String input, String output, Boolean error, Long millis)`	Record one tool call.
`final List<CodingTokenStats.MethodStat>`	`snapshot()`	Immutable per-method snapshots, sorted by output tokens (desc).
`final Unit`	`reset()`	Drop all recorded statistics and restart the "since" clock.
`final String`	`report()`	Human-readable report: one line per method (sorted by output tokens), plus a total line.

- Method Detail
  - isEmpty
```
 final Boolean isEmpty()
```
    True when nothing has been recorded yet.
  - record
```
 final Unit record(String method, String input, String output, Boolean error, Long millis)
```
    Record one tool call.
    
    Parameters:
    
    method - tool method name (e.g.
    
    input - serialized arguments the LLM sent (null → 0)
    
    output - result text returned to the LLM (null → 0)
    
    error - true when the call failed
    
    millis - wall-clock duration of the call
  - snapshot
```
 final List<CodingTokenStats.MethodStat> snapshot()
```
    Immutable per-method snapshots, sorted by output tokens (desc).
  - reset
```
 final Unit reset()
```
    Drop all recorded statistics and restart the "since" clock.
  - report
```
 final String report()
```
    Human-readable report: one line per method (sorted by output tokens), plus a total line. Compact — it is itself returned to the LLM.
