SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00150 | $0.13828 |
| Opus 5 | $0.00075 | $0.06914 |
| Sonnet 5 | $0.00030 | $0.02766 |
| Haiku 4.5 | $0.00015 | $0.01383 |
Grade A, and why
identity-posture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Identity Security Posture — Instructions
Purpose
This skill audits the identity security posture across your organization using the IdentityAccountInfo table in Microsoft Defender XDR Advanced Hunting, enriched with IdentityInfo and IdentityLogonEvents for password policy and logon activity context.
Modern organizations use multiple identity providers (Entra ID, Active Directory, Okta, SailPoint, CyberArk, Ping, etc.). IdentityAccountInfo is the only table that provides a unified identity graph across these providers, linking accounts to a single IdentityId. This skill systematically evaluates the security posture of that identity fabric.
What this skill covers:
| Domain | Key Questions Answered |
|---|---|
| 🔍 Identity Inventory | How many accounts exist? Across which providers? What types and statuses? |
| 👑 Privileged Account Audit | Who holds high-privilege roles? Across which providers? Are they permanent? |
| 🗑️ Stale & Deleted Account Hygiene | Which enabled accounts have no logon activity? Do deleted accounts retain permissions? |
| 🔑 Password Posture | Password age distribution, PasswordNeverExpires/PasswordNotRequired flags (AD accounts via IdentityInfo join) |
| 🟠 Risk Distribution | How are identity risk levels distributed? Which high-risk accounts are still active? |
| 🔗 Multi-Provider Identity Linking | Which identities span multiple IdPs? Are there status mismatches across providers? |
| 🏷️ Sensitive & Honeytoken Accounts | Which accounts are MDI-tagged? Are sensitive accounts properly protected? |
| 🏢 Organizational Context | Account distribution by department, service account inventory |
Primary data source: IdentityAccountInfo table (Advanced Hunting) — currently in Preview.
Enrichment tables:
IdentityInfo— AddsUserAccountControl(PasswordNeverExpires, PasswordNotRequired),DistinguishedName,RiskLevel,BlastRadius,PrivilegedEntraPimRoles(Preview)IdentityLogonEvents— Last logon timestamps across AD, Entra, Okta, SailPoint, M365 appsSigninLogs— Last Entra ID sign-in for stale account detection (via Data Lake for 90d+ lookback)
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

identity-posture is a skill published in the GitHub repository SCStelz/security-investigator (245 stars, last pushed 4d ago), licensed MIT. It adds 150 tokens to every session and 13,828 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
