assess-identity-architectureAssess identity trust topology, assurance boundaries, issuer and relying-party responsibilities, and failure containment before testing a specific authentication or authorization mechanism.
Assess Identity Architecture is an agent skill from cyberful/cyberful. Assess identity trust topology, assurance boundaries, issuer and relying-party responsibilities, and failure containment before testing a specific authentication or authorization mechanism.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `agents/openai.yaml` and `references/identity-architecture-review.md`).
It sits in Backend & APIs. The repository describes itself as: Cyberful is an open-source AI Red Team for discovering, exploiting, verifying, and remediating vulnerabilities. The licence is AGPL-3.0.
Read from SKILL.md and the folder at commit ec598a6. 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.
Assess Identity Architecture loads about 710 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 241 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.

.claude/skills/assess-identity-architecture/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.Model who establishes an identity fact, who transforms it, who consumes it, and which component owns the resulting security decision. Use this skill for architecture-wide assurance and failure containment; route concrete policy checks to audit-access-policy-enforcement and protocol execution to the relevant test skill.
Inventory human, workload, device, support, and external identities. For every issuer, broker, directory, authenticator, token service, gateway, relying party, policy decision point, and enforcement point, record its operator, trust anchors, identifiers, accepted assurance, revocation source, and tenant boundary.
Copy assets/identity-trust-matrix.csv when a durable topology is required. Read references/identity-architecture-review.md before assessing a federation, migration, or shared identity platform.
Trace each material claim from authoritative source to enforcement. Distinguish proofing, authentication, authorization, delegation, impersonation, and tenant selection. Check whether transformations preserve issuer, subject, audience, client, assurance, freshness, actor-versus-subject, and revocation semantics.
Challenge the architecture with loss of one trust component: compromised client, stale directory, unavailable revocation feed, confused broker, duplicated subject, tenant reassignment, support override, or clock/key transition. Determine whether the failure is contained, detected, and recoverable without trusting the failed component.
Report trust edges, authoritative owners, assumptions, unresolved evidence, concentration risk, and concrete specialist routes. An architectural weakness is not a demonstrated exploit; separate design exposure from an observed unauthorized decision.
Do not create principals, modify federation, rotate keys, or exercise recovery paths without explicit authority. Use synthetic identities and redacted claim summaries in durable artifacts.

Assess identity trust topology, assurance boundaries, issuer and relying-party responsibilities, and failure containment before testing a specific authentication or authorization mechanism. Assess Identity Architecture is an agent skill from cyberful/cyberful. Assess identity trust topology, assurance boundaries, issuer and relying-party responsibilities, and failure containment before testing a specific authentication or authorization mechanism.
Assess Identity Architecture fits situations like: backend & APIs work in your project.
Run `npx skills add cyberful/cyberful --skill assess-identity-architecture -a claude-code`. Or copy the skill folder (cyberful/builtin/skills/assess-identity-architecture in cyberful/cyberful) into .claude/skills/assess-identity-architecture in your project. Claude Code loads it when a task matches its description.
Run `npx skills add cyberful/cyberful --skill assess-identity-architecture -a codex`. Or copy the skill folder (cyberful/builtin/skills/assess-identity-architecture in cyberful/cyberful) into .agents/skills/assess-identity-architecture 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 cyberful/cyberful --skill assess-identity-architecture -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/assess-identity-architecture, .gemini/skills/assess-identity-architecture, .github/skills/assess-identity-architecture and .opencode/skills/assess-identity-architecture in your project.
SKILL.md names no scripts, command-line tools or credentials: Assess Identity Architecture 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.
Assess Identity Architecture is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 710 tokens (SKILL.md is roughly 2.8k 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 615 tokens, read only when the agent opens those files.
