Identity Access Anomaly Review is an agent skill from ahmadvh/octochains. Analyzes authentication and authorization events for failed-login clustering, privilege-escalation chains, credential-stuffing patterns, and MFA-bypass indicators.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Red teaming and adversary simulation and Authorization and RBAC. The repository describes itself as: A lightweight Python framework for parallel, isolated, collaborative AI reasoning.
Read from SKILL.md and the folder at commit 3512a57. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Identity Access Anomaly Review loads about 1.3k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 622 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.
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.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 622 words (~1,262 tokens).
“Analyze authentication, authorization, and identity-management events to determine how access was obtained and whether that access was legitimately granted. Focus strictly on the access-grant and authentication layer: how a session, credential, or privilege was acquired, not what was done with…”

Analyzes authentication and authorization events for failed-login clustering, privilege-escalation chains, credential-stuffing patterns, and MFA-bypass indicators. Identity Access Anomaly Review is an agent skill from ahmadvh/octochains. Analyzes authentication and authorization events for failed-login clustering, privilege-escalation chains, credential-stuffing patterns, and MFA-bypass indicators.
Identity Access Anomaly Review fits situations like: tasks that involve Red teaming and adversary simulation; tasks that involve Authorization and RBAC.
Run `npx skills add ahmadvh/octochains --skill identity-access-anomaly-review -a claude-code`. Or copy the skill folder (src/octochains/agents/skills/security/identity-access-anomaly-review in ahmadvh/octochains) into .claude/skills/identity-access-anomaly-review in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ahmadvh/octochains --skill identity-access-anomaly-review -a codex`. Or copy the skill folder (src/octochains/agents/skills/security/identity-access-anomaly-review in ahmadvh/octochains) into .agents/skills/identity-access-anomaly-review in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ahmadvh/octochains --skill identity-access-anomaly-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/identity-access-anomaly-review, .gemini/skills/identity-access-anomaly-review, .github/skills/identity-access-anomaly-review and .opencode/skills/identity-access-anomaly-review in your project.
SKILL.md names no scripts, command-line tools or credentials: Identity Access Anomaly Review is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Identity Access Anomaly Review has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.3k tokens (SKILL.md is roughly 5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
