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 | $0.00035 | $0.01155 |
| Opus 5 | $0.00017 | $0.00577 |
| Sonnet 5 | $0.00007 | $0.00231 |
| Haiku 4.5 | $0.00003 | $0.00115 |
Grade A, and why
xmum-application-materials 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.

XMUM Application Materials
Purpose
Use this skill when an XMUM applicant needs a practical document checklist, application timeline, official request email, recommendation plan, or submission tracker.
Requirements and university systems change. Always verify current target-program pages and current XMUM office processes before sending requests or submitting applications.
Shared Application Workspace
Before substantial materials work, check the current workspace for application-profile.md and application-tracker.md. If present, read them first, reconcile them with the latest user message, and treat them as the current source of truth.
Put stable applicant facts in application-profile.md. Put moving items such as material status, owners, deadlines, official links, target-program notes, and next actions in application-tracker.md. If the user asked Codex to maintain the workspace, update those files after meaningful decisions; otherwise return a concise update block for review.
Core Documents
Build the application folder around:
- Official transcript or official result slip.
- Completion letter, expected completion letter, enrollment proof, or graduation status proof.
- English-medium instruction proof, if useful or required.
- Ranking proof, if the applicant has a strong ranking and the target program accepts extra evidence.
- Course descriptions for prerequisite or credit matching, especially Germany, Switzerland, Sweden, Finland, Denmark, and some US/European programs.
- CV or resume.
- PS, SOP, motivation letter, diversity statement, writing sample, or research proposal where required.
- Recommendation letters or referee details.
- Language test report unless waived or allowed after offer.
- GRE/GMAT only if required or strategically useful.
- Passport, ID, certified translations, application fee receipts, and program-specific uploads.
XMUM Document Request Guidance
Use current XMUM channels, student portal instructions, department guidance, or official office contacts. Do not rely on old personal contact routes.
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.

xmum-application-materials is a skill published in the GitHub repository ViryaZheng/xmum-application-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 1,155 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
