Report spaced-repetition statistics: total facts, overdue count, retention rate, active decks, and facts added this week.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Learn Stats is an agent skill from evolution-foundation/evo-nexus. Report spaced-repetition statistics: total facts, overdue count, retention rate, active decks, and facts added this week. Use when the user says "stats", "estatísticas", "como está meu aprendizado", "/learn-stats", or wants a dashboard of their learning loop.

Its SKILL.md is about 650 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 and Statistics. The repository describes itself as: The open source operating system for AI-powered businesses.

When your agent uses it

  • The user says stats
  • Como está meu aprendizado
  • Wants a dashboard of their learning loop

Example prompts

  • “estatísticas”
  • “como está meu aprendizado”
  • “/learn-stats”
  • “/learn-stats”

Workflow steps

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

  1. Read facts
  2. Read review log
  3. Output report
  4. (optional) — List overdue facts

What it can do on your machine

Read from SKILL.md and the folder at commit 7f5dd76. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    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

Learn Stats loads about 645 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 230 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~645

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 230 words (~645 tokens).

“Reads workspace/learning/facts/ and workspace/learning/.state/review-log.jsonl to produce a markdown stats report.”
