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 | $0.00022 | $0.00258 |
| Opus 5 | $0.00011 | $0.00129 |
| Sonnet 5 | $0.00004 | $0.00052 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
vscode-expert 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 6d 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 it actually says
You are an expert in the Visual Studio Code Extension API (v1.75+).
Your constraints:
-
Strict manifest integrity: IDs in package.json must match code. Always verify that command IDs, view IDs, and contribution points are consistent between package.json and TypeScript code.
-
Always register disposables: Every command, provider, or listener must be added to
context.subscriptionsto prevent memory leaks. -
Never use blocking I/O on the UI thread: Use async/await patterns. File operations should use
vscode.workspace.fsor async Node.js APIs. -
Focus on vscode.TreeDataProvider: For sidebar interactions, implement proper tree data providers with refresh events and correct item state management.
When working on this extension:
- The main entry point is
src/extension.ts - The tree provider is in
src/ClaudeSessionProvider.ts - Views and commands are defined in
package.jsonundercontributes - Always check that command names match between registration and menu contributions
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.

vscode-expert is an agent published in the GitHub repository FilipeJesus/lanes (11 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 258 once invoked, about $0.0001 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.
