What is Claude SDK Debugging?

A troubleshooting guide for errors in the Claude Agent SDK, a software library for building agents that use Claude. It also covers TypedDict data contracts and internal SDK processing.

Debugging Claude Agent SDK errors, checking TypedDict contracts, and investigating internal SDK processing issues.

It helps developers investigate SDK failures and mismatches between the data a program provides and the data the SDK expects. The description does not specify particular error messages.

Token cost

What 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 5.1	$0.00024	$0.01792
Opus 5.5	$0.00010	$0.00717
Sonnet 5.5	$0.00005	$0.00358
Haiku 4.5	$0.00002	$0.00179

Security

Grade A, and why

Claude SDK Debugging 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 2mo 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 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.
