What is courseforge CLAUDE.md?

Project instructions for CourseForge, a tool that creates courses for Canvas, a learning-management system. They describe a pnpm and Turborepo monorepo, meaning one repository containing multiple related packages, plus its architecture and working rules.

Use them when changing CourseForge code, building or testing packages, working with Canvas connections, or adding features that need specifications and tests.

They give coding agents a shared map of the project, including which packages depend on each other, which checks to run, and how to handle tests and secrets.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00671	$0.00671
Opus 5.5	$0.00268	$0.00268
Sonnet 5.5	$0.00134	$0.00134
Haiku 4.5	$0.00067	$0.00067

Security

Grade A, and why

courseforge CLAUDE.md 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 2mo 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.

CourseForge — agent guide

AI-powered Canvas LMS course creator. pnpm + Turborepo monorepo, TypeScript, Node ≥ 22, ESM-first (dual CJS via tsup), Zod v4, Vitest, Biome.

Commands

pnpm build / pnpm test / pnpm lint / pnpm typecheck (all turbo-cached)
Single package: pnpm --filter @courseforge/imscc test
Single test file: pnpm --filter @courseforge/imscc exec vitest run src/builder.test.ts

Architecture (dependency order)

shared (CourseSpec Zod schemas) → imscc (cartridge build/parse/modify/validate) → canvas-client (REST, zero MCP deps) → mcp (MCP server). skills/ are SKILL.md dirs that call the package CLIs. Never import MCP SDK code outside packages/mcp.

Rules

Spec first: features get a docs/specs/<name>.md (contract + test matrix) before implementation.
Tests required: imscc changes need round-trip and/or golden-file coverage; client changes need MSW-mocked tests; MCP tools need schema contract + handler tests. Don't weaken snapshots to make tests pass — investigate.
Small iterations: don't bulk-generate modules; build one unit, test it, move on.
No secrets: Canvas tokens/API keys only via env (.env is gitignored). Never log tokens. Never hardcode a Canvas URL outside tests/fixtures.
Untrusted-file hardening (packages/imscc): .imscc files are untrusted input. Guard against zip-slip (reject ../absolute entry paths), zip bombs (entry count + uncompressed-size caps), and XXE (fast-xml-parser with DTD processing off). Never eval or execute cartridge content.
Canvas API invariants (packages/canvas-client): always send User-Agent; never send a body on GET (CloudFront 403s); form-encode repeated-key params (module[prerequisite_module_ids][]); paginate via RFC-5988 Link headers with per_page=100; honor 429 Retry-After with backoff; cap concurrency (semaphore, default 5).
MCP conventions (packages/mcp): every tool has Zod inputSchema, annotations (readOnlyHint for reads, destructiveHint for all writes, openWorldHint: true), and an audience. Content is created unpublished by default. Long-running jobs (imports/exports) are create → poll → report, never one blocking call.
IMSCC ground truth: when a cartridge field is ambiguous, check docs/imscc-format.md first, then Canvas's own exporter (instructure/canvas-lms lib/cc/). The course_settings/canvas_export.txt flag file and cccv1p0 extension XMLs are what make Canvas restore full fidelity — never drop them.

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.
