assemblyline-triage

assemblyline-triage is a skill for Claude Code, Codex from SauceTaster/assemblyline-mcp. It costs 75 tokens per session (757 once invoked), scanned A, original, MIT.

A skill for investigating files, hashes, URLs, and security alerts with AssemblyLine 4, a malware-analysis platform, through an MCP server.

In plain words
What is it for?
It helps analyze samples or URLs, investigate hashes, review alerts, and assess whether something may be malicious.
Why use it?
It organizes suspicious-file investigations and explains how to interpret the platform’s deployment-specific verdicts.

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

assemblyline-triage 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AssemblyLine triage

Optional. The assemblyline-mcp server already ships these workflows as MCP prompts (triage_file, investigate_hash, review_alert). This skill is a richer, Claude-specific version of the same guidance. The server is fully usable without it.

You triage malware/suspicious files through the assemblyline-mcp tools. Prefer the high-level tools; drop to raw tools only when you need detail they don't expose.

Scoring (how to read a verdict)

AssemblyLine assigns a max_score. Verdict bands use the deployment's configured thresholds (defaults below; negative = safelisted). Always report the verdict field from the digest — don't hard-code a number (a deployment may customize the thresholds; check al_help_configuration).

Score Verdict
< 0 safe (safelisted)
0–299 informative
300–699 suspicious
700–999 highly suspicious
>= 1000 malicious

Triage a file or hash

  1. al_analyze — pass sha256= for a 64-hex hash, url= for a URL, or content_base64= for raw bytes. It submits, waits, and returns a digest. If it returns state="processing", poll al_submission_digest(sid=...) until done.
  2. Report from the digest: verdict + max_score, the flagged services and notable heuristics / AV detections, the network IOCs (domains, IPs, URIs), and any extracted children (with their types). Call out errored services.
  3. To go deeper on a child or a specific service, use al_file_result, al_file_strings, or al_submission_full.

Investigate / pivot on an indicator

  • al_submission_iocs(sid) to pull the indicator set from a submission.
  • al_find_related(indicator=...) to find related submissions/files/alerts for a hash, domain, IP, or URL. Pivot on the strongest IOCs to map related activity.

Review an alert

  1. al_alert(alert_id) → score, file, status, and the linked submission sid.
  2. al_submission_digest(sid=...) for the verdict and findings.
  3. Conclude true/false positive with reasoning grounded in the score and findings.

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.
