What it does

Teach is an agent skill from stevesolun/ctx. Teach a skill or concept at the user's current level, optionally preserving a lightweight multi-session learning record.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `GLOSSARY-FORMAT.md`, `LEARNING-RECORD-FORMAT.md` and `MISSION-FORMAT.md`).

The repository describes itself as: CTX Fit finds the cheapest AI coding setup that reliably works on your repository, then applies the winner as a reviewable change. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 11b582a. 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.

    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

Teach loads about 300 tokens when it runs, and up to ~598 if it reads all its reference files. Until then it costs about 32 tokens; SKILL.md has 147 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~300
With references · SKILL.md plus every file in references/, read only if the agent opens them
~598

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.

Teach adaptively

  1. Establish the user's practical goal and current understanding. Ask one focused question when either is unclear.
  2. Choose the smallest lesson that creates a useful step forward. Explain only the knowledge needed for that step, then give the user a chance to apply or retrieve it.
  3. Use trustworthy references in proportion to the claim and stakes. Separate sourced facts from your teaching choices.
  4. Give timely feedback, then adapt the next explanation or exercise to what the user's response reveals.
  5. Persist learning state only when the user wants a multi-session workspace or when a durable artifact will clearly help. Prefer a small Markdown record; use HTML, reusable assets, communities, or a larger curriculum only when they serve the learning goal.

For a multi-session curriculum, read references/teaching-principles.md. Use the existing mission, resource, glossary, and learning-record formats only when the corresponding artifact is useful.

How many tokens does Teach use?

About 300 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 298 tokens, read only when the agent opens those files.
