bkend-data

bkend-data is a skill for Claude Code, Codex from ww-w-ai/bkit-claude-code. It costs 44 tokens per session (1,314 once invoked), scanned A, original, Apache-2.0.

A reference guide for using bkend.ai, a database service where tables store fields such as text, numbers, dates, arrays, and objects.

In plain words
What is it for?
Use it when creating, listing, viewing, deleting, or changing database tables and fields through the documented backend tools.
Why use it?
It prevents a common integration mistake: bkend.ai returns the record field as id rather than _id. It also explains field rules and available table-management tools.

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

bkend-data scanned grade A with 0 findings 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 6d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
