Skill ThomasPark20/Actioner/skills/research

On-demand CTI research and detection engineering. Use to research a threat, campaign, threat actor, CVE, or malware family, or turn an article/URL into rules — e.g. 'research the latest Volt Typhoon activity', '/actioner:research CVE-2026-1234', 'turn this writeup into Sigma rules'. Extracts IOCs and ATT&CK TTPs, generates PoC/advisory-specific detections (Splunk/CrowdStrike-portable), critic-gated, and delivers a technical analysis report.From its SKILL.md

Actioner — On-Demand Research

This is the interactive entry point. The user wants a threat investigated and turned into production-ready detection rules. The topic is in the user's message (a threat name, campaign, actor, CVE, malware family, or a URL to ingest).

How to run it — orchestrate the pipeline

The work runs in isolated subagents so the main thread stays free for the user to steer. Subagents can't spawn subagents, so you (the main thread) drive the chain with the Task tool:

DRAFT — launch the researcher subagent in DRAFT mode. Pass it: the topic/URL; the output location (the connected GitHub repo path if a sink is configured, else the current working directory); the altitude (default specific = PoC/advisory-specific; ttp/both if the user asked); leniency (default strict); and any user requirements. It returns the draft report path + a per-rule list (type, title, compile-status, confidence).
CRITIC — launch the critic subagent. Pass it: the draft report path, the threat context, the requested altitude/leniency, and the requirements. It returns a verdict (READY | NEEDS-REVISION | NO-VIABLE-DETECTION) with per-rule keep/fix/drop and confidence.
REVISE / finalize — launch the researcher subagent in REVISE mode with the draft path + the critic's verdict. It applies fixes, drops weak rules (noting what was cut), re-validates changed rules, and finalizes — writing standalone rule files when a sink is configured. (Run this even on a READY verdict so the finalize/persist step happens. On NO-VIABLE-DETECTION, skip rule work and just surface the report.)
Surface — give the user the final report path and a short summary (topic, severity, rule counts by type, confidence spread, and anything the critic dropped and why).

Steering while it runs

The user stays in the main thread. When they add a requirement mid-flight ("also check Kimsuky overlap", "only PoC/advisory-specific", "skip YARA"), capture it and feed it into the chain — relaunch the relevant step with the added constraint, or pass it as a requirement the report must satisfy before delivery. The investigation isn't complete until every stated requirement is addressed.

Detection altitude (ask once, briefly, if unstated)

Actioner generates two kinds of detection. Default to PoC/advisory-specific unless the user says otherwise:

PoC/advisory-specific (default, strict): keys on the artifact's distinctive features — exact strings, hashes, command lines, paths — from a public PoC when one exists, otherwise the advisory's specific indicators. High precision; convertible to Splunk/CrowdStrike.
Behavioral TTP (opt-in): keys on adversary behavior. Higher recall and more durable, but broader — ships at lower confidence because efficacy can't be proven without telemetry.

If the user hasn't indicated a preference, default to PoC/advisory-specific and mention a TTP layer is available on request. One short line, then proceed.

Output

A single technical analysis report following the template at ${CLAUDE_PLUGIN_ROOT}/templates/topic-summary.md, with critic-approved detection rules in ## Detection Rules, each labeled compile-status × confidence. If a GitHub repo sink is configured (see /actioner:setup), standalone rule files are also written alongside the report so the output is directly consumable by a detection pipeline; otherwise the report is produced in the working directory and surfaced to the user. If the topic was a generic advisory with no concrete artifacts, the report is delivered without rules, with a one-line explanation — that's a valid outcome, not a failure.
