What it does

Tax Ebookkeeping Context is an agent skill from kazukinagata/shinkoku. Background context for the Electronic Bookkeeping Act (電子帳簿保存法) in the shinkoku tax filing plugin. Contains requirements for electronic bookkeeping, scanner storage, mandatory electronic transaction data storage, and shinkoku's compliance status. This skill is not user-invocable — Claude loads it automatically when responding to electronic bookkeeping compliance questions.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/electronic-bookkeeping.md`).

It sits in Business, Finance & HR, covering Accounting and bookkeeping and Tax preparation. The repository describes itself as: 確定申告自動化 AI エージェントプラグイン — 帳簿管理から e-Tax 入力代行まで. The licence is MIT.

When your agent uses it

  • Tasks that involve Accounting and bookkeeping
  • Tasks that involve Tax preparation

Example prompts

  • “/tax-ebookkeeping-context”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 3つのカテゴリ(電子帳簿等保存・スキャナ保存・電子取引データ保存)を区別して説明する
  2. 電子取引データ保存の義務化(令和6年1月1日〜)を確認・案内する
  3. 優良な電子帳簿の要件と65万円控除(令和9年〜75万円控除)との関係を説明する
  4. shinkoku の電帳法対応状況(一般・優良の両要件を充足)を確認する
  5. 個人事業主向けの実務ガイダンス(最低限やるべきこと)を案内する

What it can do on your machine

Read from SKILL.md and the folder at commit 607574d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tax Ebookkeeping Context loads about 242 tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 23 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~242
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
