discover

discover is a skill for Claude Code, Codex from yohn1985/jarvisbot. It costs 39 tokens per session (435 once invoked), scanned A, original, Apache-2.0.

A discovery tool that scans a computer and records factual information about its services, network, storage, and containers. It then organizes those findings into a Markdown document, a plain-text documentation format.

In plain words
What is it for?
Use it to document a host machine, its open services and ports, network details, storage, containers, and questions worth investigating.
Why use it?
It turns a one-time inspection into saved documentation that an AI assistant can use later.

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

discover 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (skill.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

discover

The heart of Jarvis: land on a machine, look around, and write down what you learned so it becomes durable understanding instead of a one-off glance.

SCAN (pure Python/subprocess)  → bounded raw facts about the host + what it can see
ORGANIZE (LLM)                 → the brain turns raw facts into a clear, factual document
PERSIST                        → workspace/discovery/<host>-<ts>.md

Scanning is degrade-safe (any missing tool is skipped, never crashes). The organizing step runs on Jarvis's configured brain (claude/codex/ollama-cloud) — it must not invent anything not in the facts.

Usage

./install.sh skill run discover            # discover this host, write the doc
./install.sh skill run discover --print    # also print the document

Output

A markdown document describing the machine's role, services + ports, networking (interfaces, routes, neighbours/other devices), storage, containers, and an "open questions / worth investigating" list. Saved under workspace/discovery/.

Roadmap (next increments)

  • Network sweep: enumerate other devices/ports on the local subnet (consent-gated).
  • Persist findings into the knowledge/knowledge_map memory tables (staleness drives curiosity).
  • Loop integration: run on the curiosity rung so Jarvis keeps its understanding fresh on its own.
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

discover is a skill published in the GitHub repository yohn1985/jarvisbot (1 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 435 once invoked, about $0.0002 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.
