competition-windows-pivot

Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for Kerberos, WinRM, SMB, RDP, Windows credential material, replayable tickets, delegation edges, and host-to-host pivot chains. Use when the user asks to replay Kerberos material, trace a WinRM, SMB, or RDP pivot, understand host-to-host privilege movement, or prove which Windows service accepted a credential or ticket. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A concise, well-structured investigative skill that assumes competence and delegates detail to a real one-level reference. Adding concrete tool/command examples and an explicit verification feedback loop would raise actionability and workflow clarity.

Suggestions

Add one or two concrete tool/command examples per workflow step (e.g. ticket extraction and replay commands) to lift actionability toward fully executable guidance.

Insert an explicit validate→fix→retry checkpoint after replay (e.g. confirm the destination-side logon/token change before claiming the pivot succeeded) to strengthen workflow clarity for risky replay operations.

Optionally surface a couple of natural trigger synonyms (lateral movement, pass-the-ticket) in the description to round out trigger-term coverage.

DimensionReasoningScore

Conciseness

Lean and efficient with no concept padding; it assumes Claude's knowledge and every line directs action ('Inspect SAM, SECURITY, SYSTEM, NTDS, DPAPI...').

5 / 5

Actionability

Concrete targets and fields to capture are named explicitly, but as an instruction-only skill it lacks specific tool/command examples (e.g. mimikatz/sekurlsa, crackmapexec invocations), leaving minor execution gaps.

4 / 5

Workflow Clarity

A clear 3-step workflow (Recover → Trace → Report) plus a 5-step Quick Start with verify-framed steps ('Reproduce the smallest pivot that still proves the privilege edge'), though no explicit validate→fix→retry feedback loop is given.

4 / 5

Progressive Disclosure

Well-organized overview with a clearly signaled, verified one-level-deep reference ('Load `references/windows-pivot.md` for the pivot checklist...') that exists and is not nested.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that clearly states both capability and trigger conditions within a well-bounded niche. Minor keyword variations could be added, but it is highly complete and distinctive.

DimensionReasoningScore

Specificity

Lists several concrete actions — 'replay Kerberos material', 'trace a WinRM, SMB, or RDP pivot', 'understand host-to-host privilege movement', 'prove which Windows service accepted a credential or ticket' — with minor coverage gaps.

4 / 5

Completeness

Explicitly answers 'what' ('CTF-sandbox workflow for Kerberos, WinRM, SMB, RDP... pivot chains') and 'when' ('Use when the user asks to replay...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Good natural keyword coverage including protocol synonyms (Kerberos, WinRM, SMB, RDP) and replay/pivot/delegation language, though common variations like 'lateral movement' or 'pass-the-ticket' are absent.

4 / 5

Distinctiveness Conflict Risk

Clear niche scoped to a CTF-sandbox orchestrator with explicit parent routing ('Use only after `$ctf-sandbox-orchestrator`'), minimizing overlap with sibling skills.
