triage-suspicious-content

triage-suspicious-content is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 53 tokens per session (420 once invoked), scanned A, original, Apache-2.0.

A safe process for examining suspicious files, archives, installers, scripts, documents, browser extensions, URLs, QR codes, and messages before they are opened or run.

In plain words
What is it for?
Use it to preserve the original item, identify its real file type, list archive contents, inspect links and embedded code, and choose the smallest safe follow-up check.
Why use it?
It helps identify active or hidden content without triggering code or exposing the analyst to unnecessary risk.

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

triage-suspicious-content 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 1mo 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

Triage Suspicious Content

Overview

Identify the content and its active surfaces without opening, installing, importing, previewing, or following it through a handler that may execute code. Preserve the original and route the smallest useful next check.

Read references/content-preflight.md for format-specific active-content clues.

Workflow

  1. Preserve intake context.

    • Record sender/source, delivery channel, claimed purpose, filenames, timestamps, quarantine metadata, URLs as text, and why it looked suspicious.
    • Hash files and work from a copy.
  2. Identify containers before content.

    • Determine file type from bytes and structure, not extension alone.
    • List archive/package members without broad extraction and note traversal paths, symlinks, nested archives, password protection, or misleading double extensions.
  3. Inventory active surfaces.

    • Look for executables, scripts, macros, embedded files, links, forms, JavaScript, launch/install metadata, configuration payloads, extension permissions, shortened/redirecting URLs, and QR destinations.
    • Treat preview generators and importers as parsers that may be vulnerable.
  4. Check local provenance.

    • Record signatures, signer identity, notarization/quarantine evidence, package receipts/metadata, document producer, URL host and certificate context, and expected vendor distribution channel.
    • Do not infer trust from any one field.
  5. Route without execution.

    • Use reputation checking for hash/domain/vendor context, script/document analysis for active text, static malware analysis for capabilities, and reverse engineering for binary internals.
    • Select isolation before any dynamic behavior.

Output

Return intake identity, actual type/container, active surfaces, provenance observations, suspicious and benign explanations, confidence, and the first safe next 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.
