dolphindb-orca-dstream

dolphindb-orca-dstream is a skill for Claude Code from dolphindb/DolphinX_Skill. It costs 104 tokens per session (2,224 once invoked), scanned A, original, no licence file.

A coding guide for DolphinDB's Orca DStream API, which is used to describe data-stream processing workflows. It helps generate, review, and repair complete scripts for stream sources, processing steps, joins, windows, and sinks.

In plain words
What is it for?
Use it to write or review Orca stream graphs and DStream scripts, including sources, buffers, sinks, time windows, joins, rules, timers, forks, and mapping steps.
Why use it?
It reduces the work of turning a stream-processing design into a complete, working DolphinDB script. It also helps find and fix problems in Orca stream graphs and API usage.

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

dolphindb-orca-dstream 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 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.

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.
