lc-logAppend today's practice session to data/progress.txt — the daily log that is the only source for the review plan.
Lc Log is an agent skill from yennanliu/CS_basics. Append today's practice session to data/progress.txt — the daily log that is the only source for the review plan. Writes the day's line in the log's own shape (the YYYYMMDD date, the bucket labels, the | session separators), carries forward the buckets still open from yesterday, and gets the annotations right, because again / again!!! / ok / ok / todo are what the whole spaced-repetition schedule keys on. Use when asked to log practice, record what was solved today, update the progress file, or mark a problem as…
Its SKILL.md is about 2.6k 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 Education, covering Study guides and flashcards. The repository describes itself as: My CS learning : algorithm, data structure, and system design | SE.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cb6b21b. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepBashWriteEditFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
nodenpmFrom the folder's file list and the shell code blocks in SKILL.md.
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.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Lc Log loads about 2.6k tokens when it runs. Until then it costs about 170 tokens; SKILL.md has 1,371 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.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Glob, Grep, Bash, Write, EditAutomated 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.
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,371 words (~2,630 tokens).
“Append one day to data/progress.txt — the hand-written practice log that site/build-review-plan.js compiles into the review plan's data on every build. It is the only copy. Nothing else in the repo records that a problem was practised, so a line…”

Append today's practice session to data/progress.txt — the daily log that is the only source for the review plan. Lc Log is an agent skill from yennanliu/CS_basics.txt — the daily log that is the only source for the review plan.
Lc Log fits situations like: asked to log practice; record what was solved today; update the progress file; mark a problem as done.
Run `npx skills add yennanliu/CS_basics --skill lc-log -a claude-code`. Or copy the skill folder (.claude/skills/lc-log in yennanliu/CS_basics) into .claude/skills/lc-log in your project. Claude Code loads it when a task matches its description.
Run `npx skills add yennanliu/CS_basics --skill lc-log -a codex`. Or copy the skill folder (.claude/skills/lc-log in yennanliu/CS_basics) into .agents/skills/lc-log in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add yennanliu/CS_basics --skill lc-log -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lc-log, .gemini/skills/lc-log, .github/skills/lc-log and .opencode/skills/lc-log in your project.
Going by SKILL.md and its folder, Lc Log needs the command-line tools its instructions call (node and npm). Its frontmatter pre-approves these tools: Read, Glob, Grep, Bash, Write, Edit.
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
No licence was found for Lc Log or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Lc Log: Deep Reading Analyst (ginobefun/deep-reading-analyst-skill, 354 stars), Nihaisha (JuneYaooo/nihaisha-nishi-tcm, 2.2k stars), Claude Certification Tutor (rohitg00/ai-engineering-from-scratch, 66k stars) and StudyVault Quiz Tutor (bevibing/tutor-skills, 1.3k stars).
