analyze-suspicious-script-or-document

analyze-suspicious-script-or-document is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 55 tokens per session (403 once invoked), scanned A, original, Apache-2.0.

A workflow for examining suspicious scripts and active documents as data, without running them. It covers files such as shell scripts, PDFs, Office documents, and Python code.

In plain words
What is it for?
Use it to extract and decode contents layer by layer, reconstruct what would execute, and document persistence, file access, credentials, and network destinations.
Why use it?
It helps reveal hidden commands, links, embedded files, and staged payloads while reducing the risk of activating the suspicious content.

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

analyze-suspicious-script-or-document 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

Analyze Suspicious Script Or Document

Overview

Recover the execution chain as data. Use parsers and text extraction in isolation, avoid native handlers, and make each decoding transformation reproducible.

Read references/script-document-analysis.md for language and document-specific checks.

Workflow

  1. Preserve the original and identify the real container/type.
  2. Extract without activation.
    • List document members and relationships; extract text, metadata, macros, JavaScript, forms, links, embedded files, and external references with non-executing tooling.
    • Render URLs and commands as inert text.
  3. Normalize one layer at a time.
    • Decode base64/hex/URL escapes, string concatenation, compression, character arithmetic, environment substitution, and generated commands.
    • Record input, operation, tool, and output hash for every layer.
  4. Reconstruct control and data flow.
    • Identify entry conditions, interpreter, downloaded content, execution methods, persistence, credential/file access, network destinations, cleanup, and environment gates.
  5. Separate capability from execution.
    • State which branches are present, which inputs activate them, and which behaviors remain inferred.
  6. Route payloads.
    • Send recovered binaries to static/reverse analysis and use dynamic analysis only inside chosen isolation.

Guardrails

  • Do not paste decoded commands into an executing shell.
  • Do not enable macros, install profiles, follow links, or import shortcuts during static analysis.
  • Do not use a cloud document parser for private content without approval.

Output

Return container identity, recovered layers, execution chain, indicators, activation conditions, likely impact, uncertainty, and safe next step.

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.
