use-objective-see-tools

use-objective-see-tools is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 56 tokens per session (394 once invoked), scanned A, original, Apache-2.0.

A guide for using Objective-See macOS security tools to collect evidence about persistence, processes, files, network activity, code signing, and running programs. These tools observe system activity; their alerts are not automatically a final threat verdict.

In plain words
What is it for?
Use it with tools such as KnockKnock, LuLu, ProcessMonitor, FileMonitor, WhatsYourSign, or TaskExplorer during security investigation workflows.
Why use it?
It helps choose the right tool, record permissions and limitations, and verify observations with independent macOS evidence.

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

use-objective-see-tools 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 yesterday.

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

Use Objective-See Tools

Overview

Select the Objective-See tool that observes the needed surface, record its current capabilities, and return evidence to the owning macOS workflow. Do not treat one tool's label or UI color as a threat verdict.

Read references/objective-see-routing.md and recheck the official tool page before use.

Workflow

  1. Name the unresolved observation: persistence, process, file, network, signing, or process inventory.
  2. Discover local capability.
    • Verify official source, installed app/path, version, supported macOS build, permissions/system extensions, running state, and export format.
    • Do not install, approve extensions, or grant privacy access without an explicit operator decision.
  3. Select one tool and bounded action.
  4. Preserve context.
    • Record scan time, filters, exclusions, baseline, UI/CLI actions, alerts, raw/exported output, and tool errors.
  5. Correlate independently.
    • Verify signer/path/hash, process ancestry, persistence registration, socket, or file change with native evidence where practical.
  6. Route conclusions.
    • Send evidence to persistence, runtime, threat assessment, or containment workflows.

Guardrails

  • Do not enable blocking rules or terminate/delete items during evidence collection unless containment is separately approved.
  • Do not claim historical coverage when the tool was installed after the event.
  • Do not assume every Objective-See tool exposes a stable CLI or accessible GUI automation surface.

Output

Return tool/version/capability, permissions, action, observations/export, independent correlation, limitations, and owning workflow.

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.
