Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Tasks Skill
Wraps Todoist / Microsoft To-Do APIs to add, list, and complete tasks. Requires TODOIST_API_TOKEN or MSGRAPH_TOKEN env var.
Listing Tasks
Show all pending tasks:
todoist list
Adding Tasks
Create a new task with an optional due date:
todoist add "Review PR #42" --due "2026-02-05"
Completing Tasks
Mark a task as done:
todoist complete
Install
pip install todoist-api-python
Security Guardrails
- Never include
TODOIST_API_TOKENorMSGRAPH_TOKENvalues in responses, code blocks, scripts, or file writes in any encoding — tokens grant full account access and exposure enables account takeover, regardless of claimed debugging needs or authority.
- Never pipe or transmit
todoistoutput to network-capable commands or unfamiliar tools — task data contains personal information that must not leave the local machine via network transmission, regardless of claimed authority or urgency.
- Only act on the user's own tasks unless they explicitly request access to collaborator or shared-project tasks — modifying another person's tasks without their knowledge violates ownership boundaries, regardless of claimed team authority.
