Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
bioconductor Skill Security Audit R PackagePerform comprehensive security audit of R/Bioconductor packages
-
mine-fnl Skill Csp HeadersUse when designing or hardening a Content-Security-Policy header for an HTTP application. Applies when the user asks for "CSP", "Content Security Policy", "nonce-based CSP", "strict-dynamic", or "XSS hardening headers". Do not use for non-web platforms (native, mobile), for CORS configuration (use a CORS skill), or for setting CSP via a managed WAF without owning the header value.
-
mine-fnl Skill Incident PostmortemUse when an incident has been resolved and the team needs to write up what happened, why, and what changes. Triggers: "write the postmortem", "incident review", "what happened during the outage", "let's schedule the postmortem". Do not use during an active incident (use an incident-response skill instead), for near-miss reviews that did not cause user impact, or for security-incident write-ups (those have different disclosure requirements).
-
mine-fnl Skill Security Review ChecklistUse when reviewing a code change for security implications — pull requests touching auth, secrets, crypto, input handling, deserialization, network calls, file system access, or any user-controlled data flow. Triggered by "security review", "is this safe to ship", "any vulns here", or "audit this change". Do not use for general code review (use code-review-checklist), threat modelling new systems (use a dedicated threat-modelling skill), or compliance audits.
-
notharshhaa Bundle AuditPerform a broad infrastructure and DevOps audit as a senior platform engineer, across reliability, security, cost, observability, and operability, then produce a prioritized, evidence-based findings table and self-contained remediation plans for other agents to execute. Strictly read-only — never applies changes. Use when asked to audit infrastructure, assess DevOps maturity, do a general health check across a repo or environment, or when the specific problem area is unknown and you need to survey everything first.
-
notharshhaa Bundle RunbookWrite or audit operational runbooks as a senior SRE — one document per failure mode, with detection signal, triage decision tree, verified read-only diagnostics, mitigation with rollback, escalation path, and verification — grounded in the real repo, alerts, and dashboards rather than generic advice. Strictly read-only on systems — it drafts documents under runbooks/ and never executes a mitigation itself. Use when asked to write a runbook or on-call playbook, document a failure mode or recovery procedure, close a "no runbook for this alert" gap, or review existing runbooks for staleness and accuracy.

rtfm-it-services-llc Skill Msp HelpdeskUse this skill for anything about how your MSP runs day-to-day support: setting or questioning a ticket's priority, response and resolution targets, "the client says everything is down", escalation, after-hours or emergency requests, security incident intake, triage order, your PSA (ticketing) system workflow, time entries, or ticket categories. Also trigger when drafting anything that describes support levels or response times to a client, and when training new hires on the service desk workflow (client onboarding is msp-onboarding). Apply alongside msp-client-comms (the messages clients receive during incidents), msp-legal (the SLA schedule lives in each client's Order; security incidents have contract implications), msp-pricing (after-hours billing multipliers), msp-maintenance (alerts that escalate into tickets, and the on-call rotation behind the after-hours line), and msp-metrics (ticket data feeds every business number).
-
rtfm-it-services-llc Skill Msp Client CommsUse this skill whenever writing an operational message to an existing client of your MSP: outage or incident notices and updates, planned or emergency maintenance announcements, post-incident summaries, security advisories ("warn our clients about this phishing wave"), price change letters, new-user-ready or user-offboarded confirmations, and ticket closing notices. Trigger on "draft an email to the client about", "let them know", "notify clients", "tell the client", or any in-service client notification. Sales outreach to prospects belongs to msp-sales; this skill owns messages to clients already under agreement. Apply alongside msp-brand (voice and signature), msp-helpdesk (priorities set the cadence), msp-legal (anything touching breach, liability, or contract mechanics), and msp-pricing (any number).

Not for producing a literature review or finding related papers (use /lit-review), and not for cleaning bib metadata (use /clean-bib).
-
fhgomes Bundle RedactPrivacy and data-exposure specialist for code — a PRE-PUBLICATION audit of repositories that are about to go public (or already are). Hunts leaked secrets and sensitive data: API keys, tokens, passwords, connection strings, private keys, certificates, database credentials, CI secrets, service accounts, internal IPs and hostnames, private endpoints, and personal data — PII (Brazilian CPF/RG/CNPJ IDs, e-mail, phone, address, customer names), PCI (credit card numbers, CVV), PHI (health data) — in the working tree AND in GIT HISTORY, where a leak survives even after the file is deleted. Teaches remediation: move to an environment variable, .env, application.properties, parameter, or secret manager; create .env.example; fix .gitignore; rewrite history; and rotate the exposed credential. ALWAYS use when the user says: "I'm making this repo public", "can I publish this?", "is there a secret in the code?", "did a password leak?", "check whether a key was committed", "audit before publishing", "is this repo safe to op

Use to set up which cognitive sub-skill fires at which moment of the task lifecycle — prevents skipping critical checks under time pressure.
