student-ops: Instructions file for Codex

AGENTS.md

student-ops AGENTS.md is an instructions file for Codex, OpenCode from Apollo887/student-ops. It costs 551 tokens per session, scanned A, original, MIT.

A set of instructions for coding agents working in the student-ops repository. It defines onboarding checks, request routing, personal-data rules, and how application-tracker changes must be verified and recorded.

In plain words
What is it for?
It is for operating safely in the student-ops codebase. It covers loading the repository's guidance, checking deadlines, storing preferences, and adding or updating application records without duplicates.
Why use it?
Agents may act incorrectly if they skip required project context or update tracked data in the wrong way. These rules set the required checks and write process.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is Apollo887/student-ops's own configuration. It tells Codex and OpenCode how to work on student-ops itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything student-ops configures →

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

student-ops AGENTS.md 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.

AGENTS.md

Guidance for AI coding agents (Claude Code, OpenCode, Codex) operating in the student-ops repo.

Primary directive

Read CLAUDE.md first. It is the canonical system brief. Everything here is supplementary.

Before responding to any user message

  1. Silent onboarding check — does config/profile.yml exist? Does modes/_profile.md exist? If either is missing, enter onboarding before doing anything else.
  2. Load context — read CLAUDE.md, modes/_shared.md, and modes/_profile.md for scoring defaults and user customizations.
  3. Detect mode — match the user's request to a mode (see mode routing table in CLAUDE.md). If ambiguous, ask.
  4. Check deadlines — if any deadline is <3 days away, lead the response with it before whatever the user asked.

Data layer rules (CRITICAL)

  • Writes that reflect the user's personal preferences → config/profile.yml or modes/_profile.md
  • Writes that are generic system logic → NEVER. If the user wants the system changed, open an issue / PR.
  • The tracker (data/applications.md) is append-or-update — never duplicate.
  • New tracker rows go via batch/tracker-additions/ + merge-tracker.mjs. Never hand-edit.

Verification rules

  • School data (admit rates, deadlines, middle-50 stats) → verify on the school's official page via Playwright or WebFetch. Never trust WebSearch snippets alone.
  • Financial aid figures → use the exact numbers the student provided, don't estimate.
  • Claims in essays → source must be in profile.yml, a freewrite the student shared, or a prior draft. No fabrications.

Essay rules

  • Multi-pass only. Brainstorm → outline → draft → voice pass → cut. Never one-shot a final.
  • Preserve the student's voice. If you wrote it and it doesn't sound like them, rewrite it.
  • Flag clichés aggressively (see _shared.md red flags).
  • Save every version to essays/{school-slug}-{prompt}-v{n}.md.

Honest counsel

Student-ops is the friend who tells the student the truth. Specifically:

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.
