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 | $0.00036 | $0.01088 |
| Opus 5 | $0.00018 | $0.00544 |
| Sonnet 5 | $0.00007 | $0.00218 |
| Haiku 4.5 | $0.00004 | $0.00109 |
Grade A, and why
cursor-cost-optimization 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.
This is a copy
100% identical to cursor-cost-optimization — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Cursor Cost Optimization
You have access to Cursor Enterprise usage data through the cursor-usage MCP server. This skill teaches you how to identify cost-saving opportunities and recommend actionable changes.
Cost Optimization Framework
Step 1: Understand the Spend Profile
Call get_team_overview to get the baseline, then:
-
Identify the spend distribution — Is spend concentrated in a few users or spread evenly?
- If top 10% of users account for >50% of spend → focus on those users
- If spend is evenly distributed → focus on model selection policies
-
Identify the cost driver — Is it model choice, volume, or both?
- Call
get_model_usageto see which models dominate - Premium models (Opus, GPT-5) at 10-50x the cost of standard models (Sonnet, GPT-4o)
- A team of 50 where 5 people use Opus can spend more than the other 45 combined
- Call
Step 2: Model Selection Optimization
The single highest-impact cost lever is model selection.
| Task Type | Recommended Model Tier | Why |
|---|---|---|
| Code completion / tabs | Budget (Flash) | High volume, low complexity, latency-sensitive |
| Inline edits (Cmd+K) | Standard (Sonnet, GPT-4o) | Good balance of quality and cost |
| Chat conversations | Standard | Most questions don't need frontier models |
| Agent mode (complex tasks) | Premium (Opus) only when needed | Reserve for genuinely complex multi-step work |
| Code review | Standard | Pattern matching, not creative generation |
Key insight: Most developers default to the "best" model out of habit, not necessity. 80%+ of requests can be handled by standard-tier models with no noticeable quality difference.
Step 3: Spend Limits
Use set_spend_limit to set guardrails:
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-cost-optimization is a skill published in the GitHub repository ofershap/cursor-usage-plugin (2 stars, last pushed 6mo ago), licensed MIT. It adds 36 tokens to every session and 1,088 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to cursor-cost-optimization, differing in 0 lines, and is treated as a copy.
