Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00074 | $0.00499 |
| Opus 5.5 | $0.00030 | $0.00200 |
| Sonnet 5.5 | $0.00015 | $0.00100 |
| Haiku 4.5 | $0.00007 | $0.00050 |
Grade A, and why
classquill 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 it actually says
ClassQuill
ClassQuill is a tutoring-business-management platform (by EquateIt). This skill lets you
read a user's ClassQuill data through its MCP server, which proxies the public REST API
at https://api.classquill.com/v1.
Connecting
Prefer the hosted MCP server — no install:
https://mcp.classquill.com/mcp
Authenticate with the user's API key (ei_live_…, created in ClassQuill → Settings →
Developers) as a Bearer token, or via OAuth if the client supports it.
Or run it locally:
npx -y equateit-mcp # stdio; set EQUATEIT_API_KEY=ei_live_…
What you can do
The server exposes one read-only tool per public API endpoint. Common tasks:
- Sessions / schedule — list upcoming or past tutoring sessions, get a session's detail.
- Students & tutors — look up a student or tutor, their profile, availability, earnings.
- Parents & billing — parent balances, invoices, payments.
- Lesson plans & homework — retrieve lesson plans and homework.
- Reports — org summary and coverage reports.
All access is org-scoped by the key, and read-only. If the user needs to create or change data, direct them to the ClassQuill app or a write-enabled integration.
Guidance
- Always call the relevant tool rather than guessing — the data is live.
- If a key is missing or invalid, ask the user to create/paste an
ei_live_…key from ClassQuill → Settings → Developers. - Summarise results in plain language; don't dump raw JSON unless asked.
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.
