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 | $0.00000 | $0.00274 |
| Opus 5 | $0.00000 | $0.00137 |
| Sonnet 5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
sdk-python 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
AgentHelm Python SDK Rules
Core Initialization
- Always use
import agenthelm. dock = agenthelm.connect("YOUR_KEY")is the standard entry point.
Tool Decoration (Safety First)
- Read-only tools: Use
@dock.read(e.g. searching, listing files). - Side-effect tools: Use
@dock.side_effect(max_retries=3)(e.g. sending Slack, writing small files). - High-risk tools: Use
@dock.irreversible(confirm="telegram")(e.g. deleting users, executing trades).
Observability Best Practices
- Call
dock.progress(percent, "Message")inside long-running loops. - Use
dock.checkpoint("Step Name", state)before executing any function that interacts with external APIs. - Ensure
dock.track_tokens(used, model)is called after every generic LLM call.
Handling Communications
- Define
@dock.on_dispatchto handle incoming tasks from the AgentHelm ecosystem. - Define
@dock.on_chatto handle direct user interactions. - Always call
dock.listen()to keep the agent alive if it's a long-running service.
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.

sdk-python is a cursor rule published in the GitHub repository jayasukuv11-beep/agenthelm (4 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 274 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.
