What it does

Lc Faq Add is an agent skill from yennanliu/CS_basics. File an interview question and answer into doc/faq/ in the shape the other 49 FAQs use — the sheet its Scope line owns, the numbered section it belongs under, tagged code fences — and write the matching 繁體中文 overlay section in the same pass, because that tree is 100% translated and a new English answer leaves a hole the moment it lands. Use when asked to add an FAQ entry, document an interview question, answer a backend/Java/SQL/Kafka question into the notes, or start a new FAQ file. Triggers - "add a question…

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Sales & Support, covering Help center and FAQ content and Interview preparation. It works with Java, Apache Kafka, SQL and gRPC. The repository describes itself as: My CS learning : algorithm, data structure, and system design | SE.

When your agent uses it

  • Asked to add an FAQ entry
  • Document an interview question
  • Answer a backend/Java/SQL/Kafka question into the notes
  • Start a new FAQ file

Example prompts

  • “add a question about virtual threads to the java FAQ”
  • “/lc-faq-add kafka rebalancing”
  • “document this interview question”
  • “/lc-faq-add”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Find the file whose Scope line owns it
  2. Read a neighbour, then place the section
  3. Write the answer
  4. Write the 中文 section in the same pass
  5. Gate
  6. Report

What it can do on your machine

Read from SKILL.md and the folder at commit b6cade9. 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:

    • Read
    • Glob
    • Grep
    • Bash
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node
    • bash
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    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

Lc Faq Add loads about 2.2k tokens when it runs. Until then it costs about 165 tokens; SKILL.md has 1,067 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~165
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Glob, Grep, Bash, Write, Edit

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 1,067 words (~2,184 tokens).

“Add an answer to doc/faq/ and its 中文 counterpart under i18n/zh/faq/.”
