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 | $0.01779 | $0.01779 |
| Opus 5 | $0.00890 | $0.00890 |
| Sonnet 5 | $0.00356 | $0.00356 |
| Haiku 4.5 | $0.00178 | $0.00178 |
Grade A, and why
cmd-new-sdk-app 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are tasked with helping the user create a new Claude Agent SDK application. Follow these steps carefully:
Reference Documentation
Before starting, review the official documentation to ensure you provide accurate and up-to-date guidance. Use WebFetch to read these pages:
- Start with the overview: https://docs.claude.com/en/api/agent-sdk/overview
- Based on the user's language choice, read the appropriate SDK reference:
- Read relevant guides mentioned in the overview such as:
- Streaming vs Single Mode
- Permissions
- Custom Tools
- MCP integration
- Subagents
- Sessions
- Any other relevant guides based on the user's needs
IMPORTANT: Always check for and use the latest versions of packages. Use WebSearch or WebFetch to verify current versions before installation.
Gather Requirements
IMPORTANT: Ask these questions one at a time. Wait for the user's response before asking the next question. This makes it easier for the user to respond.
Ask the questions in this order (skip any that the user has already provided via arguments):
-
Language (ask first): "Would you like to use TypeScript or Python?"
- Wait for response before continuing
-
Project name (ask second): "What would you like to name your project?"
- If $ARGUMENTS is provided, use that as the project name and skip this question
- Wait for response before continuing
-
Agent type (ask third, but skip if #2 was sufficiently detailed): "What kind of agent are you building? Some examples:
- Coding agent (SRE, security review, code review)
- Business agent (customer support, content creation)
- Custom agent (describe your use case)"
- Wait for response before continuing
-
Starting point (ask fourth): "Would you like:
- A minimal 'Hello World' example to start
- A basic agent with common features
- A specific example based on your use case"
- Wait for response before continuing
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.

cmd-new-sdk-app is a cursor rule published in the GitHub repository nota-america/forgecat-agent-profiles (66 stars, last pushed yesterday), licensed Apache-2.0. It adds 1,779 tokens to every session, about $0.0089 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.
