prototype

prototype is a skill for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 30 tokens per session (345 once invoked), scanned A, original, MIT.

A method for building small, temporary working models to answer questions about how software should look or behave.

In plain words
What is it for?
Use it for interface stubs, mock data flows, and small experiments with program logic.
Why use it?
It lets you test uncertain ideas before committing to full production code.

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

prototype 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 7d 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.

[!IMPORTANT] AI Context & Knowledge Heritage

  • Failure Path: Information drift, legacy terminology, or documentation mismatch.

Executable Spiking & UX Prototyping

Raise discussion fidelity by constructing cheap, minimal, concrete prototypes to react to—UI stubs, mock data flows, or standalone logic spikes.


Operating Protocol

  1. Identify the Core Uncertainty: Is the question "how should it look" (UI layout) or "how should it behave" (state transition)?
  2. Build Minimal Executable Spike:
    • Save UI stubs or mock spikes under .tmp/prototypes/<name>/.
    • Avoid production dependencies, complex database persistence, or heavy styling.
  3. Verify with User: Demonstrate the prototype (via preview command or screenshot/recording) to lock in design choices.
  4. Transition to Production: Once approved, feed lessons learned into /plan and /to-tickets for production implementation.

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.

prototype is a skill published in the GitHub repository DDS-Solutions/AI-TadPole-OS (8 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 345 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
