What it does
Insider Threat Behavioral Analysis is an agent skill from ahmadvh/octochains. Detects anomalous behavior by authenticated users that may indicate insider threats through behavioral analysis of access patterns, privileged actions, and data movement.
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A lightweight Python framework for parallel, isolated, collaborative AI reasoning.
Example prompts
- “Use the insider-threat-behavioral-analysis skill to detect anomalous behavior by authenticated users that may indicate insider threats through…”
- “/insider-threat-behavioral-analysis”
What it can do on your machine
Read from SKILL.md and the folder at commit 3512a57. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Insider Threat Behavioral Analysis loads about 700 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 298 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 298 words (~700 tokens).
“Analyze authenticated user activity to identify behavioral deviations that may indicate potential insider misuse. Assess unusual access patterns, data movement, privileged actions, and activity timing while distinguishing between accidental negligence, suspicious behavior, and potential malicious intent.”
