flat-fee-calculator

flat-fee-calculator is a plugin for Claude Code from protomated/protomated-plugins-official. Its manifest loads nothing; the 1 skill it bundles cost 95 tokens per session together, scanned A, original, Apache-2.0.

A pricing calculator that compares hourly billing with flat-fee prices for work whose completion time changed after using AI tools. It uses your rate, task times, and matter volume to produce candidate prices in a CSV file.

In plain words
What is it for?
Use it to test flat-fee price points for repeatable legal or professional-service tasks.
Why use it?
It helps show how changing the billing model could affect revenue and margin. It keeps the calculation focused on pricing rather than legal advice.

Security

Grade A, and why

flat-fee-calculator 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 3d 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 it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 95 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
