deep-security-scan

deep-security-scan is a skill for Claude Code, Codex from ihatesea69/kiro-kit. It costs 50 tokens per session (1,275 once invoked), scanned A, original, MIT.

A rulebook and set of templates for a thorough security check of an entire code repository. It guides a process that discovers, verifies, ranks, and reports application-code vulnerabilities.

In plain words
What is it for?
Use it to run a whole-repository security assessment and produce consistent findings for developers and CI systems.
Why use it?
It gives different security checks a shared method and severity scale, while excluding issues outside its scope and reducing false alarms.

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

deep-security-scan 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-findings.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Deep Security Scan

Activate this skill when running a whole-repository deep security scan (the /security:deep-scan command). It holds the methodology the security agents share, the severity taxonomy, the hard exclusions that keep the false-positive rate low, and the finding/report templates.

When to Use

  • A user asks for a thorough, whole-repo security assessment (not a per-diff review).
  • You are orchestrating or acting as one of the security-recon, security-finder, security-triage, security-validator, security-judge, or security-reporter agents.

When NOT to Use (scope boundary)

  • Per-diff / pre-merge review → use /review:security. That is the fast gate on changed lines; this scan is the slow, whole-repo sweep.
  • Infrastructure / compliance audit (IAM, container CVEs, CIS/SOC2) → use the security-auditor agent. This scan owns application code vulnerabilities.
  • Avoid double-reporting: if a finding is purely an infra misconfiguration, defer it to security-auditor.

Methodology (three phases, per finder)

Adapted from published open-source security-review practice:

  1. Repository context — learn the frameworks, the existing sanitization/auth patterns, and the threat model BEFORE looking for bugs. (Recon produces this; finders consume it.)
  2. Comparative analysis — judge suspect code against the codebase's OWN secure patterns. Deviation from the house pattern is the strongest lead; absence of any pattern is judged against the framework's secure default.
  3. Vulnerability assessment — trace data flow from user-controlled inputs to sensitive sinks. A finding is a complete, reachable path with insufficient defense. Localize at suspicious-point (control-flow) granularity.

Pipeline shape

recon (1, serial)  →  finders (N, parallel)  [+ semgrep → triage (N, parallel), optional]
   →  validators (1 per candidate, parallel)  →  judge (1, serial dedup)
   →  reporter (1, serial)
  • Parallel finders each own a disjoint partition so they don't converge on the same obvious bug.
  • Adversarial validators try to REFUTE each candidate and score confidence 1–10; everything < 8 is dropped.
  • Serial judge dedups by ROOT CAUSE (new / better-example / duplicate) — serial so simultaneous duplicates aren't both accepted.
  • Finders write results to files incrementally, so a dead subagent doesn't lose its partition's work.

deep-security-scan is a skill published in the GitHub repository ihatesea69/kiro-kit (19 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 1,275 once invoked, about $0.0002 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 2026-09-03.
