SkillSpector: 3 findings, up to high
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 →
- high System Prompt Leakage · line 60 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.

Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00081 | $0.25263 |
| Opus 5 | $0.00041 | $0.12632 |
| Sonnet 5 | $0.00016 | $0.05053 |
| Haiku 4.5 | $0.00008 | $0.02526 |
Grade A, and why
threat-pulse scanned grade A with 1 finding 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.
Asks the agent to reveal its instructionslowSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.
□ 4. If N > 12: render top 12 (🆕 first, then memory order) + append `📋 Show full prompt pool (N items)` Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Threat Pulse — Instructions
Purpose
The Threat Pulse skill is a rapid, broad-spectrum security scan designed for the "if you only had 15 minutes" scenario. It executes 12 queries across 7 security domains in parallel, producing a prioritized dashboard of findings with drill-down recommendations to specialized investigation skills.
What this skill covers:
| Domain | Key Questions Answered |
|---|---|
| 🔴 Incidents | What incidents are open and unresolved? Prioritizes High/Critical, backfills with Medium/Low in smaller environments. How old are they? Who owns them? What was recently resolved — TP rate, MITRE tactics, severity distribution? |
| 🔐 Identity (Human) | Which users have the highest Defender XDR Risk Score (0-100)? Which are flagged by Identity Protection (RiskLevel/RiskStatus)? What risk events are driving the signals? Are there password spray / brute-force patterns? |
| 🤖 Identity (NonHuman) | Which service principals expanded their resource/IP/location footprint? |
| 💻 Endpoint | Which endpoints deviated most from their process behavioral baseline? What singleton process chains exist? |
| 📧 Email Threats | What's the phishing/spam/malware breakdown? Were any phishing emails delivered? |
| 🔑 Admin & Cloud Ops | What mailbox rules, OAuth consents, transport rules, or mailbox permission changes occurred? Is there programmatic mailbox access via API? Any MCAS-flagged compromised sign-ins? Human-initiated CA policy changes? Who performed high-impact admin operations — role assignments, MFA registration, app registration, ownership grants? |
| 🛡️ Exposure | Are any critical assets internet-facing with RCE vulnerabilities? What exploitable CVEs (CVSS ≥ 8) are present across the fleet? |
Data sources: SecurityIncident, SecurityAlert, IdentityInfo, AADUserRiskEvents, EntraIdSignInEvents, DeviceProcessEvents, DeviceLogonEvents, ExposureGraphNodes, AADServicePrincipalSignInLogs, EmailEvents, CloudAppEvents, AuditLogs, DeviceTvmSoftwareVulnerabilities, DeviceTvmSoftwareVulnerabilitiesKB
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.

threat-pulse is a skill published in the GitHub repository SCStelz/security-investigator (245 stars, last pushed 3d ago), licensed MIT. It adds 81 tokens to every session and 25,263 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
