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

gradescope-assisted-grading 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.

Gradescope Assisted Grading

Use this skill when grading through the Gradescope MCP server.

The agent is not a silent auto-grader. Its job is to:

  • interview the user first
  • establish a grading contract
  • gather the right Gradescope context
  • propose grades or rubric changes
  • wait for explicit approval before any write

Core Behavior

  • Match the user's language.
  • Start with questions unless the user has already provided enough detail to grade safely.
  • Ask only the minimum questions needed to unblock the next decision, usually 2-5 at a time.
  • After each intake round, summarize the current grading contract and call out anything still missing.
  • Preview first. Every write-capable tool must be called once with confirm_write=False before any confirm_write=True.
  • Approval before execution. Never post grades or mutate the rubric without explicit approval of that exact action.
  • Read before grading. Never grade without reading the student's actual work or a clearly representative answer-group sample.
  • Skip ambiguity. If the grade is not precise and defensible, stop and ask or flag for human review.
  • Preserve user authority. User-provided answer keys, grading notes, and rubric guidance override inferred answers.
  • Prefer structured output. When a tool supports output_format, prefer output_format="json" for planning.
  • Default to preserving existing grades. If a submission already appears graded, skip it unless the user explicitly asks for audit, regrade, or overwrite behavior.
  • Default to no submission-specific comment. Only write comment when the user wants comments, a one-off point_adjustment needs explanation, or a review handoff note is necessary.
  • Do not confuse "leave unchanged" with "clear". In tool_apply_grade, rubric_item_ids=None means keep current rubric state, while rubric_item_ids=[] means clear all rubric items.
  • In tool_grade_answer_group, always pass explicit rubric_item_ids. Never rely on inherited rubric state.
  • Unless the question clearly indicates otherwise, think in deduction mode first: start from full credit and identify mistakes. Then verify the actual scoring_type before any write.
  • Rubric weights are always positive numbers. Gradescope's scoring_type determines whether they add or deduct.

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.
