A set of operating rules for using the TickTick command-line tool to inspect information and carry out approved changes. TickTick is a task, habit, focus-timer, and calendar app.

Use it to review tasks, projects, habits, focus state, and calendar entries, or to safely prepare and perform approved TickTick updates.

It helps prevent accidental account changes by checking authentication, favoring read-only inspection, previewing changes, and asking before actions that modify data.

operator — Skill for Claude Code by MakotoUwu/ticktick-cli

Install

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.

Any agent

npx skills add MakotoUwu/ticktick-cli --skill operator

Clone the repo

git clone --depth 1 https://github.com/MakotoUwu/ticktick-cli

Made for: Claude Code.

Or install ticktick-cli, the plugin that ships this one along with the rest of its 1 skill, 2 commands.

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	$0.00035	$0.00510
Opus 5.5	$0.00014	$0.00204
Sonnet 5.5	$0.00007	$0.00102
Haiku 4.5	$0.00003	$0.00051

Security

Grade A, and why

operator 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TickTick Operator

Use the installed ticktick CLI as the primary interface to TickTick.

First step

Always start with:

ticktick auth status

If not authenticated, stop and tell the user to authenticate themselves. Never handle passwords or tokens directly.

Defaults

Prefer --output json for machine-readable responses.
Use ticktick schema and ticktick <command> --help when you need to discover command structure.
Prefer read-only commands first when exploring account state.
Use --dry-run before proposing or previewing any mutating operation.

Safe read-only commands

ticktick --output json task list --limit 20
ticktick --output json task today
ticktick --output json task overdue
ticktick --output json task search "QUERY"
ticktick --output json project list
ticktick --output json habit list
ticktick --output json focus status
ticktick --output json calendar event list --limit 10
ticktick --output json sync

Mutation policy

Ask before mutating the user's TickTick account:

task creation or edits
project or tag creation
habit check-ins or edits
focus start or stop
any delete operation

For destructive actions, require an explicit confirmation and use the CLI's --yes flags where supported.

Important product semantics

External and subscribed calendar events are read-only mirrors.
TickTick-owned calendar entries expose linkedTaskId and should be mutated through task commands, not calendar commands.
focus link is intentionally not treated as reliable live relinking. If a running focus session must be tied to a task, use a safer stop/start flow.

Natural language dates

The CLI accepts natural language date input:

ticktick --dry-run --output json task add "Review PR" --due tomorrow
ticktick --dry-run --output json task add "Plan sprint" --due "next monday"

Response style

Return IDs for created or resolved resources whenever possible.
Be explicit about whether the action was read-only, dry-run, or a real mutation.
If live behavior differs from docs or assumptions, trust the CLI output and say what you observed.

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.

operator is a skill published in the GitHub repository MakotoUwu/ticktick-cli (8 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 510 once invoked, about $0.0001 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 2026-08-31.
