From 3c711995b7380f25f771d2d5a1054adb88c04ccf Mon Sep 17 00:00:00 2001 From: Kazuki Yamada Date: Sat, 28 Mar 2026 18:53:49 +0900 Subject: [PATCH 01/11] perf(core): Replace tiktoken WASM with gpt-tokenizer and simplify metrics pipeline Replace tiktoken (WASM-based) with gpt-tokenizer (pure JS) for token counting. This eliminates ~200ms WASM initialization overhead and removes the need for a dedicated worker pool for metrics calculation. - Swap tiktoken dependency for gpt-tokenizer in package.json - Rewrite TokenCounter to use gpt-tokenizer's encode API - Remove TaskRunner/worker pool infrastructure from calculateMetrics - Remove metricsTaskRunner pre-warming from packager pipeline - Update TokenEncoding type in config schema - Simplify all metrics calculation modules to use direct token counting Co-Authored-By: Claude Opus 4.6 (1M context) --- package-lock.json | 14 +- package.json | 2 +- src/config/configSchema.ts | 4 +- src/core/metrics/TokenCounter.ts | 80 ++-- src/core/metrics/calculateGitDiffMetrics.ts | 34 +- src/core/metrics/calculateGitLogMetrics.ts | 37 +- src/core/metrics/calculateMetrics.ts | 141 +++---- src/core/metrics/calculateOutputMetrics.ts | 50 +-- .../metrics/calculateSelectiveFileMetrics.ts | 55 ++- src/core/metrics/tokenCounterFactory.ts | 15 +- .../metrics/workers/calculateMetricsWorker.ts | 8 +- src/core/packager.ts | 180 ++++----- tests/core/metrics/TokenCounter.test.ts | 125 +----- .../metrics/calculateGitDiffMetrics.test.ts | 295 +++----------- .../metrics/calculateGitLogMetrics.test.ts | 373 ++++-------------- tests/core/metrics/calculateMetrics.test.ts | 9 - .../metrics/calculateOutputMetrics.test.ts | 145 ++----- .../calculateSelectiveFileMetrics.test.ts | 37 +- tests/core/metrics/diffTokenCount.test.ts | 18 - tests/core/packager.test.ts | 5 - .../core/packager/diffsFunctionality.test.ts | 10 - tests/core/packager/splitOutput.test.ts | 5 - tests/integration-tests/packager.test.ts | 4 - 23 files changed, 467 insertions(+), 1179 deletions(-) diff --git a/package-lock.json b/package-lock.json index 0013cc8c6..6a230f4dd 100644 --- a/package-lock.json +++ b/package-lock.json @@ -19,6 +19,7 @@ "fast-xml-builder": "^1.1.4", "git-url-parse": "^16.1.0", "globby": "^16.1.1", + "gpt-tokenizer": "^3.4.0", "handlebars": "^4.7.8", "iconv-lite": "^0.7.0", "is-binary-path": "^3.0.0", @@ -30,7 +31,6 @@ "picocolors": "^1.1.1", "picospinner": "^3.0.0", "tar": "^7.5.12", - "tiktoken": "^1.0.22", "tinyclip": "^0.1.12", "tinypool": "^2.1.0", "web-tree-sitter": "^0.26.7", @@ -3121,6 +3121,12 @@ "url": "https://github.com/sponsors/ljharb" } }, + "node_modules/gpt-tokenizer": { + "version": "3.4.0", + "resolved": "https://registry.npmjs.org/gpt-tokenizer/-/gpt-tokenizer-3.4.0.tgz", + "integrity": "sha512-wxFLnhIXTDjYebd9A9pGl3e31ZpSypbpIJSOswbgop5jLte/AsZVDvjlbEuVFlsqZixVKqbcoNmRlFDf6pz/UQ==", + "license": "MIT" + }, "node_modules/handlebars": { "version": "4.7.9", "resolved": "https://registry.npmjs.org/handlebars/-/handlebars-4.7.9.tgz", @@ -4872,12 +4878,6 @@ "url": "https://bevry.me/fund" } }, - "node_modules/tiktoken": { - "version": "1.0.22", - "resolved": "https://registry.npmjs.org/tiktoken/-/tiktoken-1.0.22.tgz", - "integrity": "sha512-PKvy1rVF1RibfF3JlXBSP0Jrcw2uq3yXdgcEXtKTYn3QJ/cBRBHDnrJ5jHky+MENZ6DIPwNUGWpkVx+7joCpNA==", - "license": "MIT" - }, "node_modules/tinybench": { "version": "2.9.0", "resolved": "https://registry.npmjs.org/tinybench/-/tinybench-2.9.0.tgz", diff --git a/package.json b/package.json index ebe04e7e0..15611ad6f 100644 --- a/package.json +++ b/package.json @@ -85,6 +85,7 @@ "fast-xml-builder": "^1.1.4", "git-url-parse": "^16.1.0", "globby": "^16.1.1", + "gpt-tokenizer": "^3.4.0", "handlebars": "^4.7.8", "iconv-lite": "^0.7.0", "is-binary-path": "^3.0.0", @@ -96,7 +97,6 @@ "picocolors": "^1.1.1", "picospinner": "^3.0.0", "tar": "^7.5.12", - "tiktoken": "^1.0.22", "tinyclip": "^0.1.12", "tinypool": "^2.1.0", "web-tree-sitter": "^0.26.7", diff --git a/src/config/configSchema.ts b/src/config/configSchema.ts index dbc713d63..f1f0dbef0 100644 --- a/src/config/configSchema.ts +++ b/src/config/configSchema.ts @@ -1,5 +1,5 @@ -import type { TiktokenEncoding } from 'tiktoken';

This prevents arbitrary strings from reaching the dynamic import in `TokenCounter.loadEncoding()`. Also remove the ineffective fallback in `TokenCounter.countTokens()` that re-called the same cached function after it already threw, making the retry logic dead code.
