Turns whose only assistant tool is `Skill` collapse to category `general`
because `classifyByToolPattern` returns `'general'` and `refineByKeywords`
only operates on `coding`/`exploration`. In environments that lean on Claude
Code skills, the per-activity dashboard column flattens — every `/init`,
`/review`, `/security-review`, `/claude-api`, plus user-defined skills, all
land in `general` with no signal about which workflow ran.
Implements Option A from the issue:
- `ParsedApiCall.skills: string[]` populated in the Anthropic-path parser
via a new `extractSkillNames` helper that reads `input.skill || input.name`
from each `Skill` ToolUseBlock (mirrors `detectGhostSkills` extraction at
optimize.ts:765 so the two stay in sync).
- `ClassifiedTurn.subCategory?: string` set to the first skill name when the
resolved category is `general` AND any skill identifier was extracted.
Top-level category stays `general` — existing aggregations, exports, and
category-keyed code paths unchanged.
- `SessionSummary.skillBreakdown: Record<string, {turns,costUSD,editTurns,
oneShotTurns}>` populated in the same per-turn loop that builds
`categoryBreakdown`. Provider sessions (Codex/Cursor/etc.) keep `skills:
[]` — they don't expose the Skill tool surface today.
- Dashboard `ActivityBreakdown` renders top-N skill sub-rows beneath the
`general` row when present (indented `/skill-name`, dimmed). Other
categories render exactly as before; if no skills were invoked, the panel
is byte-identical to current output.
Existing 419 tests still pass. New `tests/classifier.test.ts` adds 8 cases:
single skill via `input.skill`, single via `input.name`, first-wins for
multi-skill turns, aggregation across multiple assistant calls in one turn,
no-name fallback (`subCategory` stays undefined), `Skill+Edit` promoting to
`coding` and dropping subCategory, non-Skill general turns, and a legacy
ParsedApiCall shape with `skills` field absent (forward-compat). Pre-fix
verification by stashing the source change reproduces 4/8 failures with the
exact "expected 'init', received undefined" diff; restoring → 8/8 pass.
Closes#203.
🤖 AI assistance disclosure: assistant-scaffolded by Claude (Opus 4.7);
author of record reviewed every line, ran the full vitest suite locally
(`npm test` → 32 files / 427 tests pass), `npx tsc --noEmit` clean, and
`npm run build` produces a clean ESM bundle.
Detects edit/test/fix retry cycles (Edit -> Bash -> Edit) within each
turn. Shows 1-shot percentage in the By Activity panel for categories
that involve code edits. Updated screenshot and README.
