tasknotes

tasknotes is a skill for Claude Code, Codex from ArtemXTech/personal-os-skills. It costs 47 tokens per session (939 once invoked), scanned A, original, MIT.

A task manager that connects an AI coding agent to tasks stored in Obsidian through the TaskNotes plugin API. Obsidian is a note-taking app, and an API lets software exchange data with it.

In plain words
What is it for?
Use it to list tasks, filter them by status or project, create tasks with priorities or schedules, update task details, change statuses, and delete tasks.
Why use it?
It removes the need to manage TaskNotes tasks manually when you want to create, find, or update them from an agent.

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

tasknotes 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/tasks.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

TaskNotes Skill

Manage Obsidian tasks via the TaskNotes plugin HTTP API.

Requirements

  1. TaskNotes plugin installed in Obsidian
  2. Enable HTTP API in TaskNotes settings:
    • Open Obsidian Settings → TaskNotes
    • Enable "HTTP API" toggle
    • Set API port (default: 8080)
    • API token: leave empty for no auth, or set a token for security
  3. Environment variables in .env file at vault root (if using auth):
    TASKNOTES_API_PORT=8080
    TASKNOTES_API_KEY=your_token_here
    
    If TaskNotes has no auth token set, you don't need a .env file.

# List all tasks
uv run scripts/tasks.py list

# List by status (use your configured status values)
uv run scripts/tasks.py list --status "in-progress"

# List by project
uv run scripts/tasks.py list --project "My Project"

# Create task
uv run scripts/tasks.py create "Task title" --project "My Project" --priority high

# Create task with scheduled time
uv run scripts/tasks.py create "Meeting prep" --scheduled "2025-01-15T14:00:00"

# Update task status
uv run scripts/tasks.py update "Tasks/task-file.md" --status done

# Add/update task description
uv run scripts/tasks.py update "Tasks/task-file.md" --details "Additional context here."

  • contexts - Array like ["office", "energy-high"]
  • due - Due date (YYYY-MM-DD)
  • scheduled - Scheduled date/time (YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS)
  • timeEstimate - Minutes (number)

Files

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.
