cursor-todo-prompt-kit: Skill for Claude Code

.cursor/skills/ct-check-task-id/SKILL.md

ct-check-task-id is a skill for Claude Code, Cursor from vguleaev/cursor-todo-prompt-kit. It costs 17 tokens per session (147 once invoked), scanned A, original, MIT.

A task-status checker that looks for a specified CT-numbered task in TODO.md, a project file that records tasks and their acceptance criteria.

In plain words
What is it for?
Use it to verify a task's completion, mark it DONE when all criteria are met, and tick the corresponding acceptance-criteria boxes.
Why use it?
It provides a consistent way to decide whether the task requirements are complete instead of relying only on a general progress note.

Skill for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also installed under .cursor/.

This is vguleaev/cursor-todo-prompt-kit's own configuration. It tells Claude Code and Cursor how to work on cursor-todo-prompt-kit itself, so it is not a mod to install elsewhere.

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

ct-check-task-id 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 2mo 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.

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.
