learnExtract reusable knowledge from the current session into a persistent skill.
Learn is an agent skill from ipea/geobr. Extract reusable knowledge from the current session into a persistent skill. Use when you discover something non-obvious, create a workaround, or develop a multi-step workflow that future sessions would benefit from.
Its SKILL.md is about 1.2k 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 Testing & QA. The repository describes itself as: Easy access to official spatial data sets of Brazil in R and Python.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 0969f92. 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:
ReadWriteBashGlobGrepFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash, yaml and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
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.
Learn loads about 1.2k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 286 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, Write, Bash, Glob, GrepAutomated 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 286 words (~1,157 tokens).
“Extract non-obvious discoveries into reusable skills that persist across sessions.”
Just SKILL.md in .claude/skills/learn of ipea/geobr.

Extract reusable knowledge from the current session into a persistent skill. Learn is an agent skill from ipea/geobr. Extract reusable knowledge from the current session into a persistent skill.
Learn fits situations like: you discover something non-obvious; create a workaround; develop a multi-step workflow that future sessions would benefit from.
Run `npx skills add ipea/geobr --skill learn -a claude-code`. Or copy the skill folder (.claude/skills/learn in ipea/geobr) into .claude/skills/learn in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ipea/geobr --skill learn -a codex`. Or copy the skill folder (.claude/skills/learn in ipea/geobr) into .agents/skills/learn 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 ipea/geobr --skill learn -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/learn, .gemini/skills/learn, .github/skills/learn and .opencode/skills/learn in your project.
SKILL.md names no scripts, command-line tools or credentials: Learn is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Bash, Glob, Grep.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. 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 Learn or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 1.2k tokens (SKILL.md is roughly 4.6k 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 Learn: Web Application Testing (anthropics/skills, 180k stars), Diagnosing Bugs (fossasia/eventyay-interpretation, 1.6k stars), TDD (pietheinstrengholt/rssmonster, 564 stars) and TDD Workflow (hellangleZ/burn-in-cceverywhere-ralph, 112 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
