The facts

Its description

Teach the user a new skill or concept, within this workspace.

The description the agent reads to decide when to use it.

From its settingsline 3

When it starts

This skill is marked `disable-model-invocation: true`, so the agent never picks it up from conversation on its own; the user has to invoke it explicitly (as `/teach`, with the topic as the argument) when they want to learn a subject over multiple sessions in the current directory as a teaching workspace.

Things a person might say (the model's guesses)

  • “/teach me yoga”
  • “/teach Rust ownership and borrowing”
  • “/teach me music theory over the next few weeks”

10## Teaching Workspace
12Treat the current directory as a teaching workspace. Workspace paths (`./lessons/` and the rest) resolve from the directory `/teach` was run in; only the `*-FORMAT.md` links resolve from this skill's folder. The state of their learning is captured in this directory in several files:
14- `MISSION.md`: A document capturing the _reason_ the user is interested in the topic. This should be used to ground all teaching. Use the format in [MISSION-FORMAT.md](./MISSION-FORMAT.md).
15- `./reference/*.html`: A directory of reference materials. These are the compressed learnings from the lessons - cheat sheets, reference algorithms, syntax, yoga poses, glossaries. They are the raw units of learning. They should be beautiful documents which print out well, and are designed for quick reference.
16- `RESOURCES.md`: A list of resources which can be explored to ground your teaching in contextual knowledge, or to acquire knowledge and wisdom. Use the format in [RESOURCES-FORMAT.md](./RESOURCES-FORMAT.md).
17- `./learning-records/*.md`: A directory of learning records, which capture what the user has learned. These are loosely equivalent to architectural decision records in software development - they capture non-obvious lessons and key insights that may need to be revised later, or drive future sessions. These should be used to calculate the zone of proximal development. They are titled `0001-<dash-case-name>.md`, where the number increments each time. Use the format in [LEARNING-RECORD-FORMAT.md](./LEARNING-RECORD-FORMAT.md).
18- `./lessons/*.html`: A directory of lessons. A **lesson** is a single, self-contained HTML output that teaches one tightly-scoped thing tied to the mission. This is the primary unit of teaching in this workspace.
19- `./assets/*`: Reusable **components** shared across lessons. See [Assets](#assets).
20- `NOTES.md`: A scratchpad for you to jot down user preferences, or working notes.

22## Philosophy
24To learn at a deep level, the user needs three things:
26- **Knowledge**, captured from high-quality, high-trust resources
27- **Skills**, acquired through highly-relevant interactive lessons devised by you, based on the knowledge
28- **Wisdom**, which comes from interacting with other learners and practitioners
30Before the `RESOURCES.md` is well-populated, your focus should be to find high-quality resources which will help the user acquire knowledge. Never trust your parametric knowledge.
32Some topics may require more skills than knowledge. Learning more about theoretical physics might be more knowledge-based. For yoga, more skills-based.

34### Fluency vs Storage Strength
36You should be careful to split between two types of learning:
38- **Fluency strength**: in-the-moment retrieval of knowledge
39- **Storage strength**: long-term retention of knowledge
41Fluency can give the user an illusory sense of mastery, but storage strength is the real goal. Try to design lessons which build long-term retention by desirable difficulty:
43- Using retrieval practice (recall from memory)
44- Spacing (distributing practice over time)
45- Interleaving (mixing up different but related topics in practice - for skills practice only)

47## Lessons
49A lesson is the main thing you produce: the unit in which knowledge and skills reach the user. Each lesson is one self-contained HTML file, saved to `./lessons/` and titled `0001-<dash-case-name>.html` where the number increments each time.
51A lesson should be **beautiful**, with clean, readable typography and layout, since the user will return to these later to review. Think Tufte.
53The lesson should be short, and completable very quickly. Learners' working memory is very small, and we need to stay within it. But each lesson should give the user a single tangible win that they can build on. It should be directly tied to the mission, and should be in the user's zone of proximal development.
55If possible, open the lesson file for the user by running a CLI command.
57Each lesson should link via HTML anchors to other lessons and reference documents.
59Each lesson should recommend a primary source for the user to read or watch. This should be the most high-quality, high-trust resource you found on the topic.
61Each lesson should contain a reminder to ask followup questions to the agent. The agent is their teacher, and can assist with anything that's unclear.

63## Assets
65Lessons are built from reusable **components**, stored in `./assets/`: stylesheets, quiz widgets, simulators, diagram helpers, and anything else a second lesson could reuse.
67Reuse is the default, not the exception. Before authoring a lesson, read `./assets/` and build from the components already there. When a lesson needs something new and reusable, write it as a component in `./assets/` and link to it; never inline code a future lesson would duplicate.
69A shared stylesheet is the first component every workspace earns: every lesson links it, so the lessons look like one consistent course rather than a pile of one-offs. As the workspace grows, so should the component library.

71## The Mission
73Every lesson should be tied into the mission - the reason that the user is interested in learning about the topic.
75If the user is unclear about the mission, or the `MISSION.md` is not populated, your first job should be to question the user on why they want to learn this.
77Failing to understand the mission will mean knowledge acquisition is not grounded in real-world goals. Lessons will feel too abstract. You will have no way of judging what the user should do next.
79Missions may change as the user develops more skills and knowledge. This is normal - make sure to update the `MISSION.md` and add a learning record to capture the change. Confirm with the user before changing the mission.

81## Zone Of Proximal Development
83Each lesson, the user should always feel as if they are being challenged 'just enough'.
85The user may specify an exact thing they want to learn. If they don't, figure out their zone of proximal development by:
87- Reading their `learning-records`
88- Figuring out the right thing to teach them based on their mission
89- Teach the most relevant thing that fits in their zone of proximal development

91## Knowledge
93Lessons should be designed around a skill the user is going to learn. The knowledge in the lesson should be only what's required to acquire that skill. You teach the knowledge first, then get the user to practice the skills via an interactive feedback loop.
95Knowledge should first be gathered from trusted resources. Use `RESOURCES.md` to keep track of them. Lessons should be littered with citations - links to external resources to back up any claim made. This increases the trustworthiness of the lesson.
97For acquiring knowledge, difficulty is the enemy. It eats working memory you need for understanding.

99## Skills
101If knowledge is all about acquisition, skills are about durability and flexibility. Make the knowledge stick.
103For skill acquisition, difficulty is the tool. Effortful retrieval is what builds storage strength. Skills should be taught through interactive lessons. There are several tools at your disposal:
105- Interactive lessons, using quizzes and light in-browser tasks
106- Lessons which guide the user through a list of real-world steps to take (for instance, yoga poses)
108Each of these should be based on a **feedback loop**, where the user receives feedback on their performance. This feedback loop should be as tight as possible, giving feedback immediately - and ideally automatically.
110For quizzes, each answer should be exactly the same number of words (and characters, if possible). Vary which position holds the correct answer across questions. Don't give the user any clues about the answer through formatting or order.

112## Acquiring Wisdom
114Wisdom comes from true real-world interaction - testing your skills outside the learning environment.
116When the user asks a question that appears to require wisdom, your default posture should be to attempt to answer - but to ultimately delegate to a **community**.
118A community is a place (online or offline) where the user can test their skills in the real world. This might be a forum, a subreddit, a real-world class (budget permitting) or a local interest group.
120You should attempt to find high-reputation communities the user can join. If the user expresses a preference that they don't want to join a community, respect it.

122## Reference Documents
124While creating lessons, you should also create reference documents. Lessons can reference these documents - they are useful for tracking raw units of knowledge useful across lessons.
126Lessons will rarely be revisited later - reference documents will be. They should be the compressed essence of the lesson, in a format designed for quick reference.
128Some learning topics lend themselves to reference:
130- Syntax and code snippets for programming
131- Algorithms and flowcharts for processes
132- Yoga poses and sequences for yoga
133- Exercises and routines for fitness
134- Glossaries for any topic with its own nomenclature
136Glossaries, in particular, are an essential reference. Once one is created, it should be adhered to in every lesson.
