When your agent uses it
- The user wants computer network exam preparation
- 408-style networking practice
- Chapter quizzes
- Subnetting calculations
Example prompts
- “/network-exam-practice”
Requirements
- Pre-approved tools (allowed-tools): file_read, file_write, document_read, kb_search, web_search_bing
What it can do on your machine
Read from SKILL.md and the folder at commit 24bde40. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
file_readfile_writedocument_readkb_searchweb_search_bing
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Network Exam Practice loads about 672 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 242 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 242 words (~672 tokens).
“Create and grade computer networking practice that matches the user's materials and exam goal. Favor original questions aligned to concepts instead of copying real exams.”
