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 | $0.00104 | $0.00860 |
| Opus 5 | $0.00052 | $0.00430 |
| Sonnet 5 | $0.00021 | $0.00172 |
| Haiku 4.5 | $0.00010 | $0.00086 |
Grade A, and why
schoolpass-curl scanned grade A 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
name: schoolpass-curl How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SchoolPass API via curl
The SchoolPass JSON API is reachable server-side — no browser, no bridge, no
extension. This skill talks to it directly with curl.
Prefer the schoolpass-mcp server for anything conversational or repeated; use
this for one-off shell work, scripts, or when the server isn't running.
Ready-to-run request bodies and jq recipes: references/requests.md.
Full shape reference: ../../docs/SCHOOLPASS-API.md.
Setup
export SCHOOLPASS_EMAIL='[email protected]'
export SCHOOLPASS_PASSWORD='…'
export SCHOOLPASS_SCHOOL_CODE=1183 # your school id (the AppCode)
export SCHOOLPASS_API_HOST=busapi-east16-ss.school-pass.net # your region's shard
Find your school id and region host by signing into your school's
<school>.school-pass.net portal, opening the new SchoolPass app, and reading
appCode (the id) and apiUrl (the host) from its localStorage.
Two rules
- Every request needs an
AppCode: <schoolCode>header. It selects your school. Omit it (or send the wrong one) and you get401. It is not a secret.references/requests.md'ssp_curlhelper adds it for you. - HTTP status codes are real.
401= the token or AppCode was rejected,403= a parent account cannot reach that route (it is admin-only),2xx= success. Branch on the HTTP code.
Auth: email/password → bearer
POST Auth/userswith{schoolCode,email,password,authType:"Credentials"}→ the identities your email owns. Take the one whoseuserTypeis3(Parent).POST Auth/tokenwith{schoolCode,userId,userType,password,authType:"Credentials"}→{ access_token, refresh_token, … }. Sendaccess_tokenasAuthorization: Bearer …on every subsequent call.
references/requests.md's sp_login does both and caches the token.
Never retry a rejected login. SchoolPass fronts its login with reCAPTCHA; repeated wrong passwords can get the account challenged and break shell login. Fix the credential and try once.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
