Summary by CodeRabbit

新機能

  • タスク管理CLI実装: Gitと統合されたターミナル完結型のタスク管理システム「task」コマンドが利用可能に。タスクの作成・表示・一覧表示・ステータス管理(開始・完了)・削除が可能
  • Git自動連携: タスク開始時に自動的にGitブランチを生成・切り替え。ブランチ名はタスク情報に基づいて自動命名
  • ローカル永続化: タスク情報をローカルに保存し、セッション間でのデータ維持とバックアップ復元に対応

ドキュメント

  • 設計書・開発ガイドラインを整備し、機能仕様、アーキテクチャ、リポジトリ構造を明文化

    specifier (triggering markdownlint MD040); update the opening fence from to a language-tagged fence such astext (or ```plaintext) so the block is
    treated as plain text — locate the ASCII-art block shown in the diff (the
    triple-backtick fence wrapping the diagram) and change its opening fence to

In @docs/functional-design.md:

  • Around line 486-514: The doc shows tasks.json as a wrapper object with
    "version", "nextId", and "tasks" but the implementation currently stores a plain

    schema by reading and writing a wrapper object instead of a raw array.
    Specifically, modify the code paths that read/write .task/tasks.json (e.g.,
    functions that loadTasks, saveTasks, and compute next IDs) so they parse the
    file into { version, nextId, tasks }, update/consume the tasks via the tasks
    property, increment nextId on create, and persist the full wrapper; ensure any

    property.

    docs/glossary.md to match the actual versions in package.json (commander
    ^11.1.0, simple-git ^3.33.0, vitest ^2.0.0) or replace the explicit versions
    with a short note like "refer to package.json for current versions"; edit the
    sections mentioning commander, simple-git, and vitest (and their related file
    references src/cli/index.ts, src/services/GitService.ts, vitest.config.ts)
    to keep the documentation and package.json consistent.
  • Line 380: Update the glossary entry in docs/glossary.md for TaskNotFoundError
    to reference its actual implementation location (the errors module) and remove
    the "will be separated in the future" note; specifically, replace the incorrect
    mention of Task.ts with a pointer to the errors implementation for
    TaskNotFoundError and delete the obsolete "将来的に" remark so the glossary matches
    the current code structure.

In @docs/repository-structure.md:

  • Around line 62-65: Update the documented ESLint filename: replace the listed
    ".eslintrc.json" entry in the repository structure snippet with
    "eslint.config.js" and ensure any surrounding text that references an ESLint
    config or flat config mentions "eslint.config.js" (update occurrences of
    ".eslintrc.json" to "eslint.config.js" and, if present, clarify that the project
    uses a flat config).

In @src/cli/formatters/ErrorFormatter.ts:

  • Around line 144-153: The message in ErrorFormatter.formatUnknownError
    incorrectly states errors are logged to ".task/error.log"; update
    formatUnknownError in src/cli/formatters/ErrorFormatter.ts to remove or replace
    that line so it reflects actual behavior (unknown errors caught by the CLI
    entrypoint like start.ts are NOT written by FileStorage.logError, which is
    private and only used for file operation errors). Locate the static method
    formatUnknownError and either delete the chalk.dim('エラーは .task/error.log
    に記録されました。') entry or change it to a truthful message (e.g., instructing the user
    to run with a verbose flag or to report the error), keeping other formatting
    intact.

In @src/services/TaskService.ts:

  • Around line 35-53: The current read-modify-write race is caused by TaskService
    methods (createTask, updateTask, deleteTask) calling loadTasks() → mutate array
    → saveTasks() without synchronization; move the locking into FileStorage so all
    callers are serialized: implement an atomic update helper on FileStorage (e.g.,
    performLockedUpdate(callback) or a locked load-and-save internally) that
    acquires an exclusive file lock (flock or equivalent), reads/parses the JSON,
    invokes the provided callback to modify the tasks array (so ID assignment like
    newId calculation happens inside the lock), writes the file atomically (write
    temp file + fs.rename), and then releases the lock; update TaskService to call
    the new locked API (or keep using loadTasks/saveTasks if FileStorage makes them
    internally locked) so createTask/updateTask/deleteTask no longer perform
    unprotected read-modify-write and cannot produce duplicate IDs or lost updates.
  • Around line 172-173: filterByStatus currently inherits getAllTasks' default
    page limit (50) and silently truncates results; update filterByStatus in
    TaskService to explicitly request all results by calling this.getAllTasks({
    status, all: true }) (or alternatively add an optional limit/all parameter to
    filterByStatus and pass it through) so the method actually returns all matching
    tasks rather than the default-limited set.
  • Around line 88-91: The current slice uses options.limit unvalidated which
    allows negatives (e.g., -1) to produce incorrect results; in TaskService where
    you check options.all and compute const limit = options.limit ?? 50 before
    calling tasks = tasks.slice(0, limit), validate that options.limit (if provided)
    is a positive integer (use Number.isInteger and > 0) and either replace invalid
    values with the default (50) or reject with a clear error (e.g., throw/return a
    BadRequest) — ensure the validated value is used in tasks.slice(0,
    validatedLimit) and include references to options.limit, limit, tasks.slice in
    the change.
  • Around line 113-141: The update block in TaskService is writing updatedAt and
    persisting even when no real changes occur and always pushes a statusHistory
    entry; modify the update logic to compute whether any field actually changed
    before mutating and saving: for title run validateTaskTitle and only assign if
    input.title !== task.title, for description and branchName only assign when
    different, and for status only push to task.statusHistory and set task.status
    when input.status !== task.status (i.e., from !== to); only update
    task.updatedAt, write back to tasks[taskIndex], and call
    this.storage.saveTasks(tasks) when at least one field changed.

In @tsconfig.json:

  • Line 6: Update the import(s) in src/example.test.ts to include the .js
    extension so they match the rest of the codebase's import style (e.g., change
    import ... from './someModule' to './someModule.js'); locate the import
    statements in src/example.test.ts and append .js to the module specifiers, and
    keep tsconfig.json's "moduleResolution": "node" as-is for now (optionally
    consider migrating to "NodeNext" later).

Nitpick comments:
In @.task/tasks.json:

  • Line 69: ファイル末尾が閉じ角括弧 ']' のみで終わっており改行がないため、ファイル末尾に改行文字(\n)を追加してください;具体的には末尾の
    ']' の後に改行を入れて保存し、エンコーディングは既存と合わせてコミットしてください。

In @docs/development-guidelines.md:

  • Around line 279-292: The fenced ASCII-art code block under the "テストピラミッド"
    section is missing a language tag which triggers the linter; update the
    triple-backtick fence that opens the pyramid block (the block containing "/\",
    "/E2E\", "ユニット" lines) to include a language specifier such as text (change totext) so the static analyzer recognizes it as a plain-text code block.
  • Around line 196-231: Add explicit language tags (e.g., text) to both commit-message code fences under the "コミットメッセージ規約(Conventional Commits)" section (the format block and the example block) and insert a blank line before and after the "Type一覧" markdown table to satisfy MD058; update the two code
    fences around the format and the example to ```text and ensure an empty line
    above the table header and one empty line after the closing table row.
  • Around line 177-183: The markdown code block containing the branch diagram
    (the lines starting with "main(本番環境・安定版)" and "└── develop(開発統合ブランチ)") lacks a
    language tag which triggers markdownlint; update that fenced code block to
    include a language specifier (use "text") so the fence becomes ```text and the
    diagram remains unchanged, then run lint to confirm the warning is resolved.

In @docs/functional-design.md:

  • Around line 426-432: Add a language specifier (use "text") to each fenced code
    block that currently contains the task tables so the blocks starting with the
    table header "ID ステータス タイトル" (the blocks around the three occurrences
    referenced) are changed from totext; update the three instances
    corresponding to the blocks beginning at the table header (the ones noted in the
    review) so the fenced blocks explicitly declare the language.

In @docs/repository-structure.md:

  • Around line 5-66: The markdown fences in repository-structure.md lack language
    tags, so add an explicit language (e.g., ```text) to every fenced code block;
    specifically update the block that begins with "task-cli/" and all other fenced
    blocks called out in the review (the ones showing tree/list outputs) to use a
    language identifier to enable syntax highlighting and satisfy the linter.

In @src/cli/commands/delete.ts:

  • Around line 105-117: Extract the duplicate parseTaskId implementation into a
    shared utility and update callers to import it: create a new module (e.g.,
    export function parseTaskId(idString: string): number) under
    src/cli/utils/parseTaskId.ts containing the existing validation logic, then
    remove the local parseTaskId functions in delete.ts, show.ts and done.ts and
    replace them with imports from that utility (import { parseTaskId } from
    "../utils/parseTaskId" or appropriate relative path), ensuring all callers use
    the new shared function.

In @src/cli/commands/done.ts:

  • Around line 136-148: confirmAction duplicates confirmDelete; extract the
    shared prompt logic into a single exported utility (e.g., function
    confirm(message: string): Promise) that uses createInterface and
    ErrorFormatter.formatConfirmPrompt, then replace the local implementations of
    confirmAction and confirmDelete with imports of this new confirm function and
    remove the duplicated code; ensure the new function preserves the same
    normalization/acceptance logic (answer.toLowerCase().trim() === 'y' || 'yes')
    and that both done.ts (confirmAction) and delete.ts (confirmDelete) import and
    call confirm(message).

In @src/cli/commands/list.ts:

  • Around line 67-74: Replace the hardcoded "50" threshold with the configured
    constant by using DEFAULT_CONFIG.defaultListLimit in the conditional and the
    user-facing message; update the check from "tasks.length >= 50" to "tasks.length

= DEFAULT_CONFIG.defaultListLimit", interpolate DEFAULT_CONFIG.defaultListLimit
into the ErrorFormatter.formatInfo message, and import DEFAULT_CONFIG from its
module (src/types/Config) if it's not already imported so the logic and message
remain consistent with the configured default.

In @src/cli/commands/start.ts:

  • Around line 59-83: The try-catch around branch operations only handles
    GitOperationError but generateBranchName can throw ValidationError; update the
    error handling in the block that calls gitService.isGitRepository(),
    gitService.generateBranchName(id, task.title) and
    gitService.createAndCheckoutBranch(branchName) to also catch ValidationError
    (same treatment as GitOperationError) and log a warning via
    ErrorFormatter.formatWarning indicating branch creation failed and that only
    task status will be updated; reference ValidationError, generateBranchName,
    createAndCheckoutBranch, and GitOperationError when making the change.

In @src/storage/FileStorage.ts:

  • Around line 58-68: The date-restoration code for tasks is duplicated in
    FileStorage (the mapping logic that converts createdAt/updatedAt and
    statusHistory.changedAt to Date objects); extract this into a private helper
    method on the FileStorage class (e.g., private restoreTaskDates(task:
    Record<string, unknown>): Record<string, unknown> or parseTaskDates) and replace
    both occurrences (the map at the top-level tasks mapping and the second mapping
    around lines 140-150) to call that helper; ensure the helper handles copying the
    task object, converting createdAt and updatedAt to Date, and mapping
    statusHistory entries to convert changedAt to Date so callers get identical
    objects.

In @src/types/errors.ts:

  • Around line 32-43: The GitOperationError constructor overwrites the original
    stack by assigning this.stack = cause.stack; instead, preserve error chaining by
    passing the cause into the Error base (use super(message, { cause }) when
    targeting ES2022+) and remove the manual stack assignment; if you need
    runtime/back-compatibility for older TS targets, avoid overwriting stack and
    instead set this.cause = cause (or wrap the cause into a custom property) so the
    original stack trace is preserved — update the GitOperationError constructor
    accordingly.

⚠️ Potential issue | 🔴 Critical

read-modify-write を排他なしで回しているため、並行実行でデータを壊します。

createTask / updateTask / deleteTask がすべて loadTasks() → 配列更新 → saveTasks() になっており、しかも src/storage/FileStorage.ts:93-108 は JSON 全体を書き戻します。別プロセスの CLI が同時に走ると last-writer-wins になり、createTask() は同じ ID を採番し得ますし、更新・削除も他方の変更を消します。排他制御は TaskService ではなく FileStorage 側で一括して入れないと防げません。

In `@src/services/TaskService.ts` around lines 35 - 53, The current
read-modify-write race is caused by TaskService methods (createTask, updateTask,
deleteTask) calling loadTasks() → mutate array → saveTasks() without
synchronization; move the locking into FileStorage so all callers are
serialized: implement an atomic update helper on FileStorage (e.g.,
performLockedUpdate(callback) or a locked load-and-save internally) that
acquires an exclusive file lock (flock or equivalent), reads/parses the JSON,
invokes the provided callback to modify the tasks array (so ID assignment like
newId calculation happens inside the lock), writes the file atomically (write
temp file + fs.rename), and then releases the lock; update TaskService to call
the new locked API (or keep using loadTasks/saveTasks if FileStorage makes them
internally locked) so createTask/updateTask/deleteTask no longer perform
unprotected read-modify-write and cannot produce duplicate IDs or lost updates.

たとえば limit = -1 だと slice(0, -1) になり、エラーではなく「最後の 1 件だけ欠けた一覧」を返します。id と同様に、ここも正の整数を検証した方が安全です。

修正案
     // 件数制限
     if (!options.all) {
       const limit = options.limit ?? 50;
+      if (!Number.isInteger(limit) || limit <= 0) {
+        throw new ValidationError(
+          '一覧件数は正の整数である必要があります',
+          'limit',
+          options.limit
+        );
+      }
       tasks = tasks.slice(0, limit);
     }

In `@src/services/TaskService.ts` around lines 88 - 91, The current slice uses
options.limit unvalidated which allows negatives (e.g., -1) to produce incorrect
results; in TaskService where you check options.all and compute const limit =
options.limit ?? 50 before calling tasks = tasks.slice(0, limit), validate that
options.limit (if provided) is a positive integer (use Number.isInteger and > 0)
and either replace invalid values with the default (50) or reject with a clear
error (e.g., throw/return a BadRequest) — ensure the validated value is used in
tasks.slice(0, validatedLimit) and include references to options.limit, limit,
tasks.slice in the change.

実質未変更でも updatedAt と履歴が更新されます。

同じ status を再設定しただけで from === to の履歴が増えますし、空更新でも updatedAt が進むので一覧順まで変わります。変更があった項目だけを反映し、差分がない場合は保存しない方が履歴として正確です。

In `@src/services/TaskService.ts` around lines 113 - 141, The update block in
TaskService is writing updatedAt and persisting even when no real changes occur
and always pushes a statusHistory entry; modify the update logic to compute
whether any field actually changed before mutating and saving: for title run
validateTaskTitle and only assign if input.title !== task.title, for description
and branchName only assign when different, and for status only push to
task.statusHistory and set task.status when input.status !== task.status (i.e.,
from !== to); only update task.updatedAt, write back to tasks[taskIndex], and
call this.storage.saveTasks(tasks) when at least one field changed.

⚠️ Potential issue | 🟠 Major

filterByStatus() が一致タスクを 50 件で黙って打ち切ります。

ここは getAllTasks({ status }) の既定上限をそのまま継承するので、メソッド名どおりの「全件フィルタ」になっていません。件数制限を残すなら API で明示し、そうでないなら { all: true } を渡した方が安全です。

In `@src/services/TaskService.ts` around lines 172 - 173, filterByStatus currently
inherits getAllTasks' default page limit (50) and silently truncates results;
update filterByStatus in TaskService to explicitly request all results by
calling this.getAllTasks({ status, all: true }) (or alternatively add an
optional limit/all parameter to filterByStatus and pass it through) so the
method actually returns all matching tasks rather than the default-limited set.

インポートスタイルの一貫性を統一してください

src/example.test.ts.js 拡張子なしでインポートしていますが、他の全プロダクションファイルは .js 拡張子を含めてインポートしています。現在の設定は allowSyntheticDefaultImports により両方のスタイルで動作しますが、コードベース全体で一貫性を保つべきです。

ESM プロジェクトの場合、すべてのインポートで .js 拡張子を明示的に含めるか、すべて省略するかのいずれかに統一することをお勧めします。

推奨される修正

src/example.test.ts のインポートを他のファイルに合わせて .js 拡張子を追加してください:

-import { add, subtract, multiply, divide } from './example';
+import { add, subtract, multiply, divide } from './example.js';

参考:"moduleResolution": "node" は ESM プロジェクトでも機能していますが、TypeScript の最新ベストプラクティスとしては "moduleResolution": "NodeNext" へのアップグレードを長期的に検討することをお勧めします。

In `@tsconfig.json` at line 6, Update the import(s) in src/example.test.ts to
include the .js extension so they match the rest of the codebase's import style
(e.g., change import ... from './someModule' to './someModule.js'); locate the
import statements in src/example.test.ts and append .js to the module
specifiers, and keep tsconfig.json's "moduleResolution": "node" as-is for now
(optionally consider migrating to "NodeNext" later).
