git-asmt-page

git-asmt-page is a skill for Claude Code, Codex from Canvas-LMS-MCP/canvas-teacher-mcp. It costs 145 tokens per session (1,357 once invoked), scanned A, original, MIT.

A builder for the Canvas page that accompanies a Git coding assignment. Git is a tool developers use to store code and track changes; the assignment itself is created in a separate repository-building step.

In plain words
What is it for?
Use it to publish an unpublished Canvas assignment page for a Git-based programming task, including its function contract or input/output rules.
Why use it?
It keeps the assignment instructions, code requirements, examples, tests, points, and grading rubric in one structured source.

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

git-asmt-page 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 12d 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.

git-asmt-page — Canvas page for a git assignment (L1 child)

The Canvas half of git-asmt. It does not build the repo (that's git-asmt-repo). It builds the page and its parts, in the standard format the global builder produces. You never hand-write the page HTML or the gDoc — you fill the asmt dict and call git_page; it renders the instruction gDoc AND the page from the same dict (so they always agree) and uploads it (unpublished).

import sys
sys.path.insert(0, "$CANVAS_LMS_ROOT/.claude/skills/assignment-page-builder")
from git_page import git_page
out = git_page(course_slug, asmt, points=N, push=True, due_at="…Z")

The parts this page must carry (the "common elements")

Every git-assignment page, built from the asmt dict:

  • Instruction — what to make: gist (1 line) + spec (what each case does) + algorithm.
  • Function contract — the core prototype, parameters, return (io: Parameter / Return lines). For a stdin program instead, the I/O is the stdin→stdout contract (no prototype).
  • Examplescall → output pairs (verbatim from the spec/slides; RUN it, paste the real result).
  • Restrictions — yellow box (what NOT to do; mirrors what the tests enforce).
  • Elaboration — navy box: exactly what the student must WRITE (graded) — algorithm, edge correctness, errors→fixes with commit links.
  • Test-items table — per grader (Compile/Run/T1..Tn) with max points and what it checks, taken from the ACTUAL test file (never invented).
  • Per-item points / Rubric — the Item | Points | Criteria table summing to points_possible (autograder / elaboration / commit / repo-link split — GRADING.md). points=N → git_page distributes by rubric_weights; never hardcode per-item numbers.
  • Request link…/classroom/issues/new?template=<request_form>&assignment=<CODE> (git_page builds it from request_id=CODE; requires the CODE registered by git-asmt-repo first). ⛔ ONE VALUE, FOUR PLACES. request_id = code = the assignment slot in the student repo name = the org-hub config.json key: <course>-<term>-A612-<student-login> · <COURSE>A612Starter · key "A612". request_id exists only for the ~1% assignment whose request key genuinely differs — passing a different value is a DECLARATION, not a default, and git_page now STOPS on a silent divergence. Why: on 2026-08-04 all 14 CSCI-19A chapter-5 pages shipped assignment=5-6-style TITLES while the register held A56, and nothing noticed for a whole chapter — the student request form is a dropdown generated from config.json, so students picked the right entry and the broken pre-fill stayed invisible.
  • Full guide — the embedded instruction gDoc (git_page makes it in pages_folder).

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.
