Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00059 | $0.02416 |
| Opus 5.5 | $0.00024 | $0.00966 |
| Sonnet 5.5 | $0.00012 | $0.00483 |
| Haiku 4.5 | $0.00006 | $0.00242 |
Grade A, and why
todoist-api 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 419 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Todoist CLI Skill
This skill provides procedural guidance for working with Todoist using the td CLI tool.
Prerequisites
The td CLI must be installed and authenticated. Verify with:
td auth status
If td is not installed or not authenticated:
- Not installed: Tell the user to install with
npm install -g @doist/todoist-cli - Not authenticated: Tell the user to run
td auth loginto authenticate via OAuth
Output Formats for Agents
For machine-readable output, use these flags:
--json- Output as JSON array--ndjson- Output as newline-delimited JSON (one object per line)--full- Include all fields in JSON output (default shows essential fields only)
Confirmation Requirement
Before executing any destructive action, always ask the user for confirmation using AskUserQuestion or similar tool. A single confirmation suffices for a logical group of related actions.
Destructive actions include:
- Deleting tasks, projects, sections, labels, or comments
- Completing tasks
- Updating existing resources
- Archiving projects
Read-only operations do not require confirmation.
Quick Commands
| Command | Description |
|---|---|
td add "text" |
Quick add with natural language parsing |
td today |
Tasks due today and overdue |
td upcoming [days] |
Tasks due in next N days (default: 7) |
td inbox |
Tasks in Inbox |
td completed |
Recently completed tasks |
Quick Add Examples
td add "Buy milk tomorrow p1 #Shopping"
td add "Call dentist every monday @health"
td add "Review PR #Work /Code Review"
The quick add parser supports:
- Due dates:
tomorrow,next monday,Jan 15 - Priority:
p1(urgent) throughp4(normal) - Project:
#ProjectName - Section:
/SectionName - Labels:
@label1 @label2

Filters:
--project <name>- Filter by project name or id:xxx--label <name>- Filter by label (comma-separated for multiple)--priority <p1-p4>- Filter by priority--due <date>- Filter by due date (today, overdue, or YYYY-MM-DD)--filter <query>- Raw Todoist filter query--assignee <ref>- Filter by assignee (me or id:xxx)--workspace <name>- Filter to workspace--personal- Filter to personal projects only
What ships with it
2 files 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.
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.

todoist-api is a skill published in the GitHub repository intellectronica/agent-skills (297 stars, last pushed 6mo ago), licensed CC0-1.0. It adds 59 tokens to every session and 2,416 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
