poc-builder

poc-builder is a skill for Claude Code, Codex from vinodhini-sd/build-with-coco. It costs 108 tokens per session (6,477 once invoked), scanned B, original, no licence file.

A tool for turning Snowflake learning material or a topic into a working proof of concept (POC), a small demonstration of an idea. It studies the source, plans the demo, finds relevant account data, and builds the POC interactively.

In plain words
What is it for?
Use it to build a Snowflake demo from a guide, blog post, documentation link, social post, GitHub repository, or topic name.
Why use it?
It removes the need to read the source, design the demo, and search for suitable data separately. It helps move from an idea to something runnable.

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 B, and why

poc-builder scanned grade B 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 2mo 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

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.
