jarvis-use

jarvis-use is a skill for Claude Code, Codex from jarvis-intelligence/jarvis-index. It costs 50 tokens per session (2,003 once invoked), scanned A, original, no licence file.

A code-structure search tool for finding symbol definitions, references, callers, type and call hierarchies, document symbols, and related code by meaning.

In plain words
What is it for?
It helps trace functions and types, locate definitions, find usages, and search a codebase semantically.
Why use it?
It makes it easier to understand how code is connected than searching only for matching text.

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.

Security

Grade A, and why

jarvis-use 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 today.

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.

jarvis-use is a skill published in the GitHub repository jarvis-intelligence/jarvis-index (4 stars, last pushed yesterday), with no licence file. It adds 50 tokens to every session and 2,003 once invoked, about $0.0003 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 2026-08-31.
