What it does

Learn Review is an agent skill from evolution-foundation/evo-nexus. Review spaced-repetition facts that are due today. Applies SM-2 algorithm to update interval, ease, and nextreview in each fact's frontmatter. Updates review-log.jsonl. Use when the user says "revisar", "review facts", "study", or "/learn-review".

Its SKILL.md is about 1.3k 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: The open source operating system for AI-powered businesses.

When your agent uses it

  • The user says revisar
  • Tasks that involve Study guides and flashcards

Example prompts

  • “s frontmatter. Updates review-log.jsonl. Use when the user says”
  • “review facts”
  • “/learn-review”
  • “/learn-review”

Workflow steps

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

  1. Scan for due facts
  2. Review loop (one fact at a time)
  3. Apply SM-2 and update file
  4. Append to review log
  5. Next fact

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 json).

    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 Review loads about 1.3k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 546 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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 546 words (~1,320 tokens).

“Reviews facts in workspace/learning/facts/ whose next_review date is today or in the past. Applies SM-2 grading and rewrites frontmatter in-place. Records every grade in workspace/learning/.state/review-log.jsonl.”
