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.

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 | $0.00081 | $0.00240 |
| Opus 5 | $0.00041 | $0.00120 |
| Sonnet 5 | $0.00016 | $0.00048 |
| Haiku 4.5 | $0.00008 | $0.00024 |
Grade A, and why
cursor 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 yesterday.
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.
What it actually says
Cross-Agent Task Runner — Cursor Agent CLI
Procedures
Step 1: Self-Call Detection
- Check for
CURSOR_SESSIONorCURSOR_TRACE_IDenvironment variable. - If detected, stop and inform the user: "Cannot invoke Cursor from within Cursor. Use a different target CLI."
Step 2: Execute Shared Procedure
- Read
references/shared-procedure.mdfor the core workflow (mode inference, context gathering, prompt construction, result presentation). - Read
references/cli-cursor.mdfor Cursor-specific flags, model selection heuristics, and version compatibility matrix. - Follow the shared procedure using the Cursor-specific details.
What ships with it
3 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.

cursor is a skill published in the GitHub repository darshitpp/x-agent (2 stars, last pushed 23d ago), licensed MIT. It adds 81 tokens to every session and 240 once invoked, about $0.0004 per session on Opus 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.
