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.
npx agentmods add rules/wyattowalsh/agents/cursor-modelsgit clone --depth 1 https://github.com/wyattowalsh/agentsWhat 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 | $0.00404 | $0.00404 |
| Opus 5 | $0.00202 | $0.00202 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00040 | $0.00040 |
Grade A, and why
cursor-models 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 2d 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 Model Pin
When calling Task or launching subagents, always set model to cursor-grok-4.5-high.
Do not:
- Omit
modelonTasklaunches (soft rule — Phase B still allows omit so the High parent can inherit) - Pass
inherit,cursor-grok-4.5-fast,cursor-grok-4.5,composer-*, Claude, GPT, Terra, or Sol slugs - Rely on Explore’s faster default — operators SHOULD set CLI
exploreSubagentModel: "inherit"in user-owned~/.cursor/cli-config.json(sync SHALL NOT writecli-configor livestate.vscdb)
Custom agents under .cursor/agents/ (and managed home agents) are pinned to cursor-grok-4.5-high.
Layer matrix (SSOT)
| Layer | Mechanism | Omit model |
Wrong/fast model | Hook crash |
|---|---|---|---|---|
| Soft rule | .cursor/rules/cursor-models.mdc |
Agents must not omit | Agents must not pass | N/A |
| Phase A | preToolUse Task rewrite |
Pins to High via updated_input |
Rewrites + clears alts | fail-open (Task proceeds) |
| Phase B | subagentStart allowlist |
Allow (inherit High parent) | Deny if explicit non-High | fail-open |
| Validate/CI | validate_hooks + pytest |
N/A | N/A | Compensatory: projection must exist |
Security Enforce guards (beforeShellExecution, etc.) stay fail-closed (RV-004). Pin hooks stay fail-open.
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-models is a cursor rule published in the GitHub repository wyattowalsh/agents (5 stars, last pushed 11d ago), licensed MIT. It adds 404 tokens to every session, about $0.0020 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.
