backlog-notation

backlog-notation is a skill for Claude Code, Codex from nulab/bee. It costs 201 tokens per session (1,478 once invoked), scanned A, original, MIT.

A syntax reference for Backlog notation, a text-formatting system used by some Nulab Backlog projects. Backlog projects may instead use Markdown, so the project’s selected format matters.

In plain words
What is it for?
Use it to write or edit formatted Backlog text when the project uses Backlog notation, including headings, lists, links, and other supported formatting.
Why use it?
It prevents formatted text from appearing as literal symbols when posting issue descriptions, comments, wiki pages, or pull requests in Backlog.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

backlog-notation scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

backlog-notation

Backlog notation (Backlog記法) syntax reference.

When this applies

Every Backlog project is set to one text formatting rule: Markdown (the default for new projects) or Backlog notation. This reference covers Backlog notation only. It is not a Backlog-wide standard, and it does not apply to Markdown projects — in those, write plain Markdown and ignore everything below.

Backlog renders text strictly by the project's rule: Backlog notation posted to a Markdown project (or vice versa) is not converted — it shows up as literal characters like ''bold'' or **bold**. Determine the rule like this:

  1. The user or project instructions (AGENTS.md, CLAUDE.md) already state the rule — the usual case. Follow what is stated; do not spend an API call re-verifying it.

  2. The rule is not stated anywhere — check it once before posting:

    bee project view -p PROJECT_KEY --json textFormattingRule
    # {"textFormattingRule":"backlog"}   -> use this reference
    # {"textFormattingRule":"markdown"}  -> use Markdown instead
    

    If you cannot run bee (e.g. this skill is installed without it), fetch /api/v2/projects/PROJECT_KEY from the Backlog API and read textFormattingRule, or ask the user.

Backlog notation is not Markdown — never mix the two syntaxes in one text.
