Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00079 | $0.02439 |
| Opus 5 | $0.00039 | $0.01220 |
| Sonnet 5 | $0.00016 | $0.00488 |
| Haiku 4.5 | $0.00008 | $0.00244 |
Grade A, and why
conducting-phishing-incident-response 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 9d 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.

The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Conducting Phishing Incident Response
When to Use
- A user reports receiving a suspicious email via the phishing report button or abuse mailbox
- Email gateway detects a malicious email that bypassed initial filtering
- Threat intelligence indicates an active phishing campaign targeting the organization
- A user confirms they clicked a link or opened an attachment from a suspicious email
- Credentials have been entered on a suspected phishing page
Do not use for business email compromise (BEC) involving compromised internal accounts; use BEC response procedures which focus on account takeover investigation.
Prerequisites
- Email security gateway with message trace and quarantine capabilities (Microsoft Defender for Office 365, Proofpoint, Mimecast)
- Microsoft 365 admin access or Google Workspace admin for mailbox search and purge
- Malware sandbox for attachment and URL analysis (ANY.RUN, Joe Sandbox, Hybrid Analysis)
- Email header analysis tools (MXToolbox Header Analyzer, Google Admin Toolbox)
- Identity provider access for account remediation (Azure AD, Okta, Duo)
- Phishing report intake process (dedicated mailbox or integrated report button)
Workflow
Step 1: Receive and Triage the Phishing Report
Evaluate the reported email to determine if it is malicious:
- Extract the email as an .EML or .MSG file (preserves headers)
- Analyze email headers to determine the true sender, relay path, and authentication results

Classification criteria:
- Confirmed Phishing: Malicious URL/attachment, spoofed sender, credential harvesting page
- Suspicious: Anomalous headers but no confirmed malicious content
- Spam/Marketing: Unwanted but not malicious
- Legitimate: Not a phishing email (false report)
What ships with it
3 files 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.

conducting-phishing-incident-response is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 2,439 once invoked, about $0.0004 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 2026-09-03.
