Implementing Identity Verification For Zero Trust is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Implements continuous, risk-adaptive identity verification for zero trust using phishing-resistant MFA (FIDO2/WebAuthn), risk-based conditional access, and identity governance aligned with NIST SP 800-207 and the CISA Zero Trust Maturity Model Identity Pillar. Use when designing zero trust identity controls, deploying phishing-resistant MFA, or building conditional access policies based on device posture, behavior, and location.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).
It sits in Security, covering Access reviews and audit trails. It works with Microsoft Entra ID and Okta. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. 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.
Ships 2 files in scripts/ (Python), which the agent can run.
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.
Implementing Identity Verification For Zero Trust loads about 2.4k tokens when it runs, and up to ~5.5k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 808 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); the scripts in this folder are not scanned.

.claude/skills/implementing-identity-verification-for-zero-trust/SKILL.md (or your agent's skills folder). This skill also uses 7 other files; get the full folder from GitHub.Identity is the foundational pillar of zero trust architecture. NIST SP 800-207 mandates that all resource authentication and authorization are dynamic and strictly enforced before access is allowed. Identity verification in zero trust goes beyond traditional username/password by implementing continuous, risk-adaptive authentication using multiple signals including device posture, behavioral biometrics, location, and network context.
This skill covers implementing phishing-resistant MFA, continuous identity verification, risk-based conditional access, and identity governance aligned with the CISA Zero Trust Maturity Model Identity Pillar.

└────────┘ └──────────────┘FIDO2/WebAuthn eliminates phishable credentials by binding authentication to the origin domain. Hardware security keys and platform authenticators provide cryptographic proof of identity without transmitting secrets.
Rather than authenticating once at session start, zero trust requires ongoing verification through session token evaluation, behavioral analytics, and periodic re-authentication challenges based on risk signals.
Conditional access policies evaluate multiple signals (user risk level, sign-in risk, device compliance, location) to dynamically adjust authentication requirements and access grants.
AI-driven analytics detect compromised identities through impossible travel detection, anomalous sign-in patterns, credential stuffing detection, and token replay attacks.

Run `npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill implementing-identity-verification-for-zero-trust -a claude-code`. Or copy the skill folder (skills/implementing-identity-verification-for-zero-trust in mukul975/Anthropic-Cybersecurity-Skills) into .claude/skills/implementing-identity-verification-for-zero-trust in your project. Claude Code 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 mukul975/Anthropic-Cybersecurity-Skills --skill implementing-identity-verification-for-zero-trust -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/implementing-identity-verification-for-zero-trust, .gemini/skills/implementing-identity-verification-for-zero-trust, .github/skills/implementing-identity-verification-for-zero-trust and .opencode/skills/implementing-identity-verification-for-zero-trust in your project.
Going by SKILL.md and its folder, Implementing Identity Verification For Zero Trust needs Python for the scripts in its folder. Our summary lists: Python 3.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Implementing Identity Verification For Zero Trust is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.2k tokens, read only when the agent opens those files.
