A read-only command-line bridge to Canvas and other learning-management systems, the websites schools use for courses and grades. It reads assignments, grades, due dates, calendar events, and teacher announcements.

In plain words
What is it for?

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

schoolbridge 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 yesterday.

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.

schoolbridge — assignments, grades & announcements

schoolbridge is a read-only CLI bridge to the student's school LMS (Canvas first; provider-pluggable). It never submits, messages, or changes anything at school — it only reads.

Setup (once)

Run schoolbridge courses. If it errors with "Canvas is not configured":

  1. Ask the user for their school's Canvas URL and an access token (created in Canvas → Account → Settings → Approved Integrations → "+ New Access Token").
  2. Run: schoolbridge init --base-url <url> --token <token>

If the school instead issued an OAuth Developer Key (third-party app access), authorize in the browser with: schoolbridge auth login --base-url <url> --client-id <id> --client-secret <secret> — tokens then refresh automatically.

If the student can't create a token (some schools disable it; the mobile app has no token button), fall back to the zero-credential calendar feed: have them open Canvas in a web browser → Calendar → "Calendar Feed" (bottom-right) → copy the .ics URL, then run: schoolbridge init --provider ics --feed-url <url> This covers assignments, due dates, calendar events, ranking, and study plans — but not grades, announcements, or feedback, so skip those features and say why if asked.

The token/secret values are secrets — never repeat them back in conversation or logs. For testing without credentials, add --provider mock to any command to get realistic sample data.

Commands (add --json for machine-readable output)

  • schoolbridge upcoming --json [--days N] — work due in the next N days (default 7) across all courses, plus recent overdue unsubmitted work. Each item carries priority (0–100) and priorityLabel (critical/high/medium/low), status (unsubmitted/submitted/graded/missing/ overdue), dueInHours, points, and URLs.
  • schoolbridge grades --json — current grade per course plus everything graded in the last two weeks with scores.
  • schoolbridge announcements --json [--days N] — teacher announcements, newest first (default: last 14 days).
  • schoolbridge assignment <courseId> <assignmentId> --json — one assignment with its full instructions as plain text. Use this before building a study plan.
  • schoolbridge calendar --json [--days N] — upcoming course calendar events (review sessions, field trips, in-class tests; default: next 30 days).
  • schoolbridge feedback --json [--days N] — teacher comments on the student's submitted work (default: last 14 days).
  • schoolbridge events --jsoneverything that changed since the last check: new assignments, due-date changes, posted/changed grades, new announcements, new discussions, new or rescheduled calendar events, newly published course content and files, new teacher feedback, and course-grade moves. One JSON object per line; empty output means nothing new. The first run ever saves a baseline and prints nothing.

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.
