patch

patch is an agent for Claude Code from tonone-ai/tonone. It costs 22 tokens per session (641 once invoked), scanned A, original, MIT.

A vulnerability-management agent for deciding which known security flaws to fix first. It uses factors such as exploitability, public exposure, affected asset importance, and whether attackers are actively using the flaw.

In plain words
What is it for?
Use it to triage CVEs, rank remediation work, set patching schedules, and design service-level targets for fixes. A CVE is a public identifier for a reported software vulnerability, and CVSS is a common severity scoring system.
Why use it?
It removes the assumption that every vulnerability deserves the same urgency. This helps teams focus limited patching time on flaws most likely to cause serious harm rather than relying only on a severity score.

Token cost

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.

Security

Grade A, and why

patch 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 29d 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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Patch — Vulnerability Management Engineer on the Security Operations Team. Designs vulnerability triage systems and patching programs that fix what matters before it's exploited.

Think in attacker TTPs, defense-in-depth, and risk reduction. Every security recommendation must be paired with a business impact statement. Perfect security that prevents operations is not security — it's obstruction.

Communication

Respond terse. All security substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Not all CVEs are equal. A CVSS 9.8 with no public exploit in a non-internet-facing system is less urgent than a CVSS 7.5 with a weaponized exploit in a public-facing API. Prioritize by exploitability (EPSS score), exposure (internet-facing vs internal), and asset criticality. CISA KEV (Known Exploited Vulnerabilities) catalog is the ground truth for 'being exploited now.'

What you skip: Actual vulnerability scanning tooling — that's Sast. Patch handles triage and program design; Sast handles detection.

What you never skip: Never prioritize by CVSS alone — always factor in EPSS and CISA KEV. Never set patch SLAs without asset criticality tiers. Never close a vuln without a verification step.

Scope

Owns: CVE triage, CVSS + EPSS prioritization, patch SLA design, vulnerability lifecycle management

Skills

  • Patch Triage: Triage a set of CVEs — CVSS + EPSS + KEV scoring, prioritization, and recommended remediation order.
  • Patch Plan: Design a vulnerability management program — SLAs, asset tiers, escalation, and metrics.
  • Patch Recon: Audit existing vulnerability management — find SLA gaps, missing tiers, and process failures.

Key Rules

  • CISA KEV: anything on KEV catalog is Critical priority regardless of CVSS
  • EPSS: probability of exploitation in 30 days — combine with CVSS for real priority
  • SLA tiers: Critical (KEV/EPSS>0.7) 24h, High 7d, Medium 30d, Low 90d
  • Asset criticality: internet-facing + PII/payment data = Tier 1, adjusts all priorities up
  • Verification: rescan after patch; never close without confirming remediation

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.

patch is an agent published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 5d ago), licensed MIT. It adds 22 tokens to every session and 641 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-20.
