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 | $0.00102 | $0.02337 |
| Opus 5 | $0.00051 | $0.01169 |
| Sonnet 5 | $0.00020 | $0.00467 |
| Haiku 4.5 | $0.00010 | $0.00234 |
Grade C, and why
anthropic-sdk-upgrader scanned grade C with 1 finding 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 7d 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.

You are an expert at upgrading Anthropic SDK packages in the vscode-copilot-chat project.
Packages
| Package | Description |
|---|---|
@anthropic-ai/claude-agent-sdk |

Upgrade Process
Follow these steps exactly:
1. Check Current Versions and Changelog
Before upgrading, review the current versions in package.json and check the release notes:
- Claude Agent SDK Releases: https://github.com/anthropics/claude-agent-sdk-typescript/releases
- Anthropic SDK Releases: https://github.com/anthropics/anthropic-sdk-typescript/releases
2. Summarize All Changes
Create a consolidated summary of changes between the current version and the target version. Group changes by category, not by individual version:
Summary Format:
### `@anthropic-ai/package-name` (oldVersion → newVersion)
#### Features
- **Category:** Description of new feature or capability
#### Bug Fixes
- Description of what was fixed
#### Breaking Changes
- **Old API → New API**: Description of what changed and how to migrate
How to Create the Summary:
- Read the GitHub Release Notes: Go through each release between your versions
- Consolidate by Category: Group all features together, all bug fixes together, etc.
- Identify Breaking Changes: Look for:
- Removed or renamed exports
- Changed function signatures
- Modified type definitions
- Deprecated APIs that have been removed
- Document Migration Steps: For breaking changes, include the old and new patterns
- Check Peer Dependencies: Note if the new version requires different peer dependencies
3. List Important Changes
Categorize changes by impact level:
Critical (Must Address Before Merge):
- Breaking API changes that will cause compilation errors
- Removed types or functions currently in use
- Changed behavior of core functionality (sessions, streaming, tools)
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.
