The resulting monolith made each responsibility harder to evolve safely and likely triggered function-length and file-size linter violations in the project's existing lint rules. All of these concerns operate on shared data models (`TokenUsageSummary`, `TokenCoreMetrics`, etc.) that needed to remain accessible across the responsibilities. + +### Decision + +We will decompose `pkg/cli/token_usage.go` into six focused files within the same `cli` package, each owning one domain boundary: + +- `token_usage_models.go` — shared data models and `TokenUsageSummary` helper methods (`TotalTokens`, `AvgDurationMs`, `ModelRows`) +- `token_usage_parser.go` — token/agent usage file discovery and JSONL parsing, ambient-context extraction +- `token_usage_aic.go` — usage JSONL scanning and AI Credits derivation/population +- `token_usage_steering.go` — proxy event parsing and steering-event classification +- `token_usage_subagent.go` — subagent model-request extraction and request-vs-observed attribution +- `token_usage.go` — reduced to orchestration (`analyzeTokenUsage`, `analyzeTokenUsageAICOnly`) and package-level constants + +The existing public API surface and all behavioral semantics (fallback order, steering count integration, per-model aggregation) are preserved without change. + +### Alternatives Considered + +#### Alternative 1: Retain the monolith with internal grouping + +Keep all logic in `token_usage.go` and improve navigability via region comments, blank-line separators, or `//nolint:cyclop` directives to suppress lint. This is the lowest-change option and avoids introducing new files. It was rejected because it does not reduce the cognitive surface — a reader editing AIC logic must still open a file that also contains steering-event and subagent attribution code. It also does not address the root cause of the linter violations. + +#### Alternative 2: Move each responsibility into its own sub-package + +Create separate packages (e.g., `pkg/cli/tokenusage/parser`, `pkg/cli/tokenusage/aic`) with explicit import boundaries. This would enforce isolation at the compiler level. It was rejected because it would require significant refactoring of the call sites in `token_usage.go` and would make cross-concern access (e.g., `TokenUsageSummary` shared between parser and AIC) more verbose without delivering proportional benefit at this codebase scale. All of the data types are tightly coupled by design. + +### Consequences + +#### Positive +- Each file is now under 500 LOC and covers a single concern, making it easier to read, test, and extend any one subsystem in isolation. +- Satisfies existing linter rules on function and file length without suppression annotations. +- Clearer module boundaries serve as implicit documentation of the domain model's structure. + +#### Negative +- All six files share the same `cli` package, so there is no enforced package-level isolation; a future developer can still mix concerns freely without compiler feedback. +- The number of files to navigate during a code review increases from one to six, requiring reviewers to understand the overall split before they can follow a single data flow. + +#### Neutral +- No changes to public API surface or externally observable behavior; callers of `analyzeTokenUsage` and `analyzeTokenUsageAICOnly` are unaffected. +- The decomposition boundary is a convention, not a contract — future contributors should consult this ADR before adding new logic to decide which file is the right owner. + +--- + +*ADR created by [adr-writer agent].
