What is gws-classroom?

A command-line interface for Google Classroom, Google’s service for managing classes, students, teachers, assignments, and coursework. It provides commands for working with Classroom courses and related resources.

Use it to create, view, or delete courses and work with Classroom resources. Some operations depend on the requester’s role and permissions.

It lets an agent manage Classroom data through documented commands instead of manually navigating the web interface. The instructions also describe permission and not-found errors.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00017	$0.01543
Opus 5	$0.00009	$0.00772
Sonnet 5	$0.00003	$0.00309
Haiku 4.5	$0.00002	$0.00154

Security

Grade A, and why

gws-classroom 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 11d 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.

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.
