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 5.1 | $0.00000 | $0.00306 |
| Opus 5.5 | $0.00000 | $0.00122 |
| Sonnet 5.5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
cursor-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 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.
What it actually says
Cursor optimization
Keep this as a short operations guide. Put long tutorials in documentation/.
Session context hygiene
- Prefer precise
@references to relevant files over broad repo prompts. - Keep
.cursorignore/.cursorindexingignorecurrent to avoid indexing build artifacts and generated output. - Start a new chat for unrelated tasks to reduce stale context carry-over.
MCP usage
- Daily default should stay lightweight:
github,linear,slack. - Enable high-footprint servers (AWS suites, analytics suites) only when the task explicitly needs them.
- Avoid duplicate connector sources (project MCP + plugin for the same service).
- Keep local server package versions pinned for reproducibility; avoid unbounded
@latestin long-lived configs.
Verification feedback loop
- Use native lint diagnostics and project scripts (
make lint,pnpm check, targetedpytest) after edits. - Fix newly introduced errors before expanding scope.

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-optimization is a cursor rule published in the GitHub repository jaycewalzer1/SilverKey-Inc. (2 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 306 tokens. 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.
