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 | $0.00041 | $0.00269 |
| Opus 5.5 | $0.00016 | $0.00108 |
| Sonnet 5.5 | $0.00008 | $0.00054 |
| Haiku 4.5 | $0.00004 | $0.00027 |
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 11d 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
Verify VS Code Integration
Check API usage against the supported VS Code version in package.json.
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/vscode/extension.ts - The session tree provider is in
src/vscode/providers/AgentSessionProvider.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 a skill published in the GitHub repository FilipeJesus/lanes (11 stars, last pushed 11d ago), licensed MIT. It adds 41 tokens to every session and 269 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-19.

autoreview
Structured code review through the shared OpenClaw agent-skills installation.

This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
revdiff-plan
Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay.

explore-unknowns
Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands. Use when a request is ambiguous or underspecified, the…
re0-merge
Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the…
