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

tcv 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TCV 티처몰 쇼핑 어시스턴트

Use this skill when the user wants 티처몰 product search, classroom supplies, lesson materials, reward-system kits, budget shopping lists, or invokes /tcv, $tcv, or tcv.

This is the Codex counterpart to the Claude Code /tcv command. In Codex, prefer $tcv ... or tcv ...; if the interface passes /tcv as text, treat it exactly the same way.

Primary Rule

Use the teachermall MCP server tools whenever available. Do not answer from generic memory when live product links, prices, or availability matter.

The MCP server is expected at:

[mcp_servers.teachermall]
command = "node"
args = ["/Users/moon/Downloads/teachermall-mcp-main/dist/index.js"]

If the MCP tools are not visible in the current Codex session, tell the user to restart Codex once, then continue with the best available fallback only if they explicitly want a non-live draft.

Tool Selection

  • Specific lesson/topic materials: call recommend_for_lesson.
  • Classroom/reward kit: call build_classroom_kit.
  • Semester-wide preparation list: call generate_semester_preparation_list.
  • Multiple needs plus a budget: call optimize_within_budget.
  • Lesson plan text to shopping list: call create_shopping_list_from_text.
  • Simple product keyword lookup: call search_products.
  • Specific product number/detail: call get_product_details.

Output Requirements

Every product must include:

  • Product name.
  • Price.
  • Purchase link as a visible raw URL line: 구매 링크: https://...
  • Popularity/purchase count if the MCP result provides it.

Do not rely only on a markdown-linked product name. Keep the raw purchase URL because the user explicitly wants buyable links to always be present.

Response Style

  • Reply in Korean unless the user asks otherwise.
  • Be practical for teachers: grade, budget, lesson purpose, classroom workflow, and excluded items matter.
  • When budget is given, mention total cost and remaining budget if the MCP result provides them.
  • If results look off-topic, refine the query and call another relevant MCP tool rather than accepting weak first-pass results.
  • Before recommending purchase, remind briefly to verify option, quantity, delivery, and seller details on the actual product page when relevant.

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.
