Teknium db22efbe88 feat(optional-skills): declare platforms frontmatter for all 63 undeclared skills
Extends the Windows-gating work to the optional-skills/ tree. Every
SKILL.md that previously omitted the platforms: field now carries an
explicit declaration, which Hermes's loader (agent.skill_utils.
skill_matches_platform) honors to skip-load on incompatible OSes.

58 skills declared cross-platform (platforms: [linux, macos, windows]):

5 skills gated from Windows (platforms: [linux, macos]):
  mlops/flash-attention   - Flash Attention wheels are Linux-first; Windows
                            install requires building from source with CUDA
  mlops/faiss             - faiss-gpu has no Windows wheel; gate rather than
                            leak partial (faiss-cpu) support
  mlops/nemo-curator      - NVIDIA NeMo ecosystem has no first-class Windows path
  mlops/slime             - Megatron+SGLang RL stack is Linux-only in practice
  mlops/whisper           - openai-whisper + ffmpeg setup on Windows is
                            non-trivial; gate until Windows install stanza lands

Methodology: scanned every SKILL.md for Windows-hostile signals
(apt-get, brew, systemd, osascript, ptrace, X11 binaries, POSIX-only
Python APIs, Docker POSIX $(pwd) bind-mounts, explicit 'linux-only' /
'macos-only' text). 3 skills flagged as having hard signals on review:
docker-management and qdrant only had POSIX $(pwd) docker examples and
the tools themselves (Docker Desktop, Qdrant) run fine on Windows —
declared ALL. whisper had an apt/brew ffmpeg install path and nothing
else but the openai-whisper Windows install story is rough enough to
warrant gating.

Strict-over-lenient policy: when in doubt, gate. Easier to un-gate after
verified Windows support lands than to leak partial support that
manifests as mid-task failures for Windows users.

Canvas LMS — Course & Assignment Access

Read-only access to Canvas LMS for listing courses and assignments.

Scripts

  • scripts/canvas_api.py — Python CLI for Canvas API calls

Setup

  1. Log in to your Canvas instance in a browser
  2. Go to Account → Settings (click your profile icon, then Settings)
  3. Scroll to Approved Integrations and click + New Access Token
  4. Name the token (e.g., "Hermes Agent"), set an optional expiry, and click Generate Token
  5. Copy the token and add to ~/.hermes/.env:
CANVAS_API_TOKEN=your_token_here
CANVAS_BASE_URL=https://yourschool.instructure.com

The base URL is whatever appears in your browser when you're logged into Canvas (no trailing slash).

Usage

CANVAS="python $HERMES_HOME/skills/productivity/canvas/scripts/canvas_api.py"

# List all active courses
$CANVAS list_courses --enrollment-state active

# List all courses (any state)
$CANVAS list_courses

# List assignments for a specific course
$CANVAS list_assignments 12345

# List assignments ordered by due date
$CANVAS list_assignments 12345 --order-by due_at

Output Format

list_courses returns:

[{"id": 12345, "name": "Intro to CS", "course_code": "CS101", "workflow_state": "available", "start_at": "...", "end_at": "..."}]

list_assignments returns:

[{"id": 67890, "name": "Homework 1", "due_at": "2025-02-15T23:59:00Z", "points_possible": 100, "submission_types": ["online_upload"], "html_url": "...", "description": "...", "course_id": 12345}]

Note: Assignment descriptions are truncated to 500 characters. The html_url field links to the full assignment page in Canvas.

API Reference (curl)

# List courses
curl -s -H "Authorization: Bearer $CANVAS_API_TOKEN" \
  "$CANVAS_BASE_URL/api/v1/courses?enrollment_state=active&per_page=10"

# List assignments for a course
curl -s -H "Authorization: Bearer $CANVAS_API_TOKEN" \
  "$CANVAS_BASE_URL/api/v1/courses/COURSE_ID/assignments?per_page=10&order_by=due_at"

Canvas uses Link headers for pagination. The Python script handles pagination automatically.

Rules

  • This skill is read-only — it only fetches data, never modifies courses or assignments
  • On first use, verify auth by running $CANVAS list_courses — if it fails with 401, guide the user through setup
  • Canvas rate-limits to ~700 requests per 10 minutes; check X-Rate-Limit-Remaining header if hitting limits

Troubleshooting

Problem Fix
401 Unauthorized Token invalid or expired — regenerate in Canvas Settings
403 Forbidden Token lacks permission for this course
Empty course list Try --enrollment-state active or omit the flag to see all states
Wrong institution Verify CANVAS_BASE_URL matches the URL in your browser
Timeout errors Check network connectivity to your Canvas instance
