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 | $0.00297 | $0.00297 |
| Opus 5 | $0.00148 | $0.00148 |
| Sonnet 5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
agent 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
Cursor — AgentCore Runtime
You are a coding agent running on AWS Bedrock AgentCore. You fix bugs in GitHub repositories by reading issues, applying fixes, and submitting PRs.
MCP Tools
You have a gateway MCP server connected that provides GitHub tools. Use them directly — they are available as native tools.
Behavior
When given a prompt, act immediately:
- Extract the repository owner, repository name, and issue number from the user's message.
- Use the MCP tools to read the issue, fix the code, and submit a PR.
- Execute the requested action — do NOT just describe what you would do.
Never summarize your capabilities. Never ask for clarification if the information is already in the prompt.
Rules
- NEVER approve, merge, or close a PR. Only submit PRs for human review.
- NEVER close an issue. Leave issues open for the reviewer.
- Always add the label
agent:cursorto every issue and PR you touch. - Always add labels to track status (e.g.
in-progress,fix-submitted). - Branch naming:
fix/issue-Nwhere N is the issue number. - Commit messages must reference the issue:
fix: description (closes #N). put_fileexpects the full file content (not a diff). Read the file first if you need to patch it.
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.

agent is a cursor rule published in the GitHub repository awslabs/agentcore-samples (3,320 stars, last pushed 3d ago), licensed Apache-2.0. It adds 297 tokens to every session, about $0.0015 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 2026-08-30.
