start-course

name	start-course
description	Initialise a learning session. Checks for an existing journal in progress/<course-slug>/journal.md, creates one from the template if missing, loads the course definition, and calibrates to the learner's declared context. Use when starting a new course or resuming after a break.
metadata	{"version":"1.0"}

Purpose

This skill sets up a learning session. It handles two scenarios:

• New course — creates the journal and learner context, calibrates the tutor, and orients the learner on what's ahead.
• Resuming — loads existing progress, recalibrates, and picks up where the learner left off.

The skill ensures the tutor never starts cold. By the time the learner begins working, the tutor knows who they are, what course they're taking, and where they are in it.

Before You Start

Read these files — they must be in your context before continuing:

1. references/JOURNAL-TEMPLATE.md — journal scaffold with placeholders and scribe instructions
2. references/LEARNER-CONTEXT.md — measurement checklist for the learner context interview, output format, and interview tips

---

Procedure

Step 1 — Identify the course

Scan core/courses/ and custom/courses/ for directories containing a COURSE.md file. Each is an available course.

• One course found — use it automatically. Confirm with the learner: "I found [title]. Starting that one?"
• Multiple courses found — list them by title and slug. Ask the learner which one they want to start.
• No courses found — tell the learner there are no courses available and suggest using /create-course to scaffold one.

Step 2 — Read the course definition

Read the selected COURSE.md. Extract:

• Course title, slug, and domain
• Target Dreyfus level and target audience
• Course Structure section — modules and assignments (titles, descriptions, topic checklists)
• Reasoning Review Prompts per assignment
• Prerequisites (if any)

If the course has prerequisites, check whether the learner has completed them (look in progress/ for completed journals). Warn if prerequisites are unmet — but don't block. The learner decides.

Step 3 — Create or load the journal

Check if progress/<slug>/journal.md exists.

If it does not exist (new course):

Create the journal from references/JOURNAL-TEMPLATE.md:

1. Copy the template content below the <!-- JOURNAL START --> marker
2. Replace placeholders:
   • {course-title} — from COURSE.md title
   • {learner-name} — from profile/PROFILE.md if it exists, otherwise ask the learner
   • {start-date} — today's date (YYYY-MM-DD)
   • {progress-tracker} — generate from COURSE.md assignments:

     - [ ] **Assignment 1: Title**
     - [ ] **Assignment 2: Title**
     

   • {assignment-sections} — generate one section per assignment using the Per-Assignment Section Structure from the template:

     ## Assignment N: Title
     
     **Goal:** {from COURSE.md assignment description}
     
     ### What I Attempted
     
     ### Mistakes and Corrections
     
     ### Got It Right
     
     ### What Clicked
     

3. Write to progress/<slug>/journal.md. Create the progress/<slug>/ directory if it does not exist.

If it does exist (resuming):

Read the existing journal. Note which assignments are completed (checked in the Progress Tracker) and which is next.

Step 4 — Create or load the learner context

Check if progress/<slug>/learner-context.md exists.

If it does not exist (new course):

Interview the learner using references/LEARNER-CONTEXT.md as the measurement checklist. Walk through all 6 fields conversationally:

1. Prior Skills Relevant to This Course
2. Mental Models Being Brought In
3. Level in This Subject (offer the Dreyfus scale)
4. Prior Exposure to This Subject
5. Learning Preferences
6. Prior Upstack Courses Completed

Before asking, read the course's target audience and target Dreyfus level from COURSE.md — the garment spec tells you what body type this garment is designed for. Use it to ask better questions.

If profile/PROFILE.md exists, read it first. Some answers may already be covered by the profile — acknowledge what you already know and probe for course-specific details rather than re-asking generics.

Write the answers to progress/<slug>/learner-context.md using the output format defined in the template.

If it does exist (resuming):

Read the existing learner context. Do not re-interview.

Step 5 — Commit progress files

If new files were created in Steps 3–4:

git add progress/<slug>/ && git commit -m "progress: start <slug>"

If resuming with no new files, skip this step.

Step 6 — Update AGENTS-CUSTOM.md Active Course section

Read the root AGENTS-CUSTOM.md file. Find the <!-- start-course --> comment. Replace everything from that comment up to (and including) the --- separator that follows the Active Course content with:

<!-- start-course -->
## Active Course

**Course:** {title}
**Slug:** {slug}
**Path:** {core/courses or custom/courses}/{slug}/COURSE.md
**Journal:** progress/{slug}/journal.md
**Learner Context:** progress/{slug}/learner-context.md

---

This ensures the tutor has the active course in context on every session load without needing to re-run the skill.

Step 7 — Calibrate

Read calibration sources in this order:

1. profile/PROFILE.md (if it exists) — the learner's full background across all courses. See .agents/skills/core/configure-profile/references/PROFILE-TEMPLATE.md §"How the Tutor Reads the Profile" for per-section guidance.
2. progress/<slug>/learner-context.md — course-specific context. How this learner's background applies to this particular course.

Profile first (who you are), then context (how your background applies here). Together they tell you:

• What analogies will land (prior skills + mental models)
• What level to pitch at (Dreyfus level in this subject)
• What transfer errors to watch for (mental models from other domains)
• How to interact (learning preferences)

Step 8 — Summarise and orient

Present the learner with a brief summary:

For a new course:

• Course title and what it covers (1–2 sentences from COURSE.md)
• Number of assignments and their titles
• Where to begin (Assignment 1)
• A note that the journal will be maintained automatically

For a resuming learner:

• Where they left off (last completed assignment, or current in-progress assignment)
• What's next
• Any relevant context from the journal (last session's key takeaways, if available)

End with an invitation to begin: "Ready to start Assignment 1?" or "Ready to pick up where you left off?"

Notes

• The learner context interview is a conversation, not a form. Ask one question at a time, respond to the answer, then move on. See references/LEARNER-CONTEXT.md §Tips for the Tutor During Measurement for guidance on probing, overstatement/understatement, and using the conversation itself as calibration data.
• Don't block on missing profile. If profile/PROFILE.md does not exist, the learner context alone is sufficient for calibration. Suggest running /configure-profile later for richer calibration across future courses, but don't require it.
• Commit before the interview, not after. If the journal is created but the learner context interview hasn't started yet, don't commit. Wait until both files exist (or just the journal, if resuming and context already exists), then commit once.
