tutorial-check

tutorial-check is a skill for Claude Code, Codex from bearded-illirian/trailmark. It costs 102 tokens per session (1,772 once invoked), scanned A, original, MIT.

A read-only validator for the QUICKSTART tutorial. It runs checks on the project database and files to confirm that a sample project, workspace, logged skill use, and task artifacts were created correctly.

In plain words
What is it for?
Use it after completing the QUICKSTART homework to verify the project, task workflow, generated files, and Flow UI entry.
Why use it?
It shows which tutorial steps were completed and gives a short hint for fixing each failed check. It confirms setup without changing the workspace.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tutorial-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Tutorial-Check Protocol

Homework validator for the QUICKSTART walkthrough. Runs 5 checks against the user's workspace to confirm they set up their first real project correctly. Reports ✅/❌ per step with a one-line remediation hint.

Read-only — never modifies files or DB.


When to invoke

After the user completes the 5-step homework in docs/QUICKSTART.md § 5:

  1. Create a project named my-tutorial
  2. Start a task in that project (/go-start + /go-fast)
  3. Approve the full chain (ok, ok, 1)
  4. Verify 5 artifact files exist in tasks/log/{slug}/
  5. Confirm the task appears in Flow UI

Then the user runs /tutorial-check and gets pass/fail per step.


Step 0 — Detect workspace root

Find the workspace root by walking up from CWD until we find framework.yml or manifest.yml at the same level. If none found within 5 levels — abort:

⚠️ Not inside a framework workspace. Run this from anywhere inside your
   framework directory (where framework.yml lives).

Set {workspace_root} for all subsequent checks.


Step 1 — Run the 5 checks

Each check is independent — a failure in one doesn't skip the others.

Check 1: Project my-tutorial created

test -d "{workspace_root}/projects/my-tutorial" && D1=✅ || D1=❌
grep -q "id: my-tutorial" "{workspace_root}/aihub/projects.yml" && D2=✅ || D2=❌
test -L "{workspace_root}/projects/my-tutorial/.claude/skills" && D3=✅ || D3=❌

Pass = D1 AND D2 AND D3. Remediation: bash bin/new-project my-tutorial

Check 2: Task started in that project

COUNT=$(sqlite3 "{workspace_root}/tasks/routing.db" \
  "SELECT COUNT(*) FROM artifacts WHERE project = 'my-tutorial'")
test "$COUNT" -gt 0 && CHECK2=✅ || CHECK2=❌

Pass = at least one artifact row exists. Remediation: cd projects/my-tutorial && claude, then /go-start and /go-fast "...".

Check 3: Chain approved (plan-first artifact exists)

COUNT=$(sqlite3 "{workspace_root}/tasks/routing.db" \
  "SELECT COUNT(*) FROM task_artifacts ta
   JOIN artifacts a ON ta.task_id = a.id
   WHERE a.project = 'my-tutorial' AND ta.artifact_type = 'plan-first'")
test "$COUNT" -gt 0 && CHECK3=✅ || CHECK3=❌

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
