Summary

Pre-deployment security audit for web applications, organized by OWASP Top 10:2025 categories. Use when reviewing code before shipping, auditing an existing application, or when users mention "security review," "ready to deploy," "going to production," or express concern about vu

2
3	Pre-deployment security audit organized around the OWASP Top 10:2025 categories (released late 2025, succeeding the 2021 edition). This is the baseline that prevents obvious disasters — not a substitute for a real penetration test or threat model. For verification depth beyond this checklist, see OWASP ASVS 5.0 (https://owasp.org/www-project-application-security-verification-standard/). For API-specific scope, see OWASP API Security Top 10:2023 (https://owasp.org/API-Security/editions/2023/en/0x00-header/).

5	## Step 0: Research the current security landscape (do this first)

7	> Security knowledge ages on a 6-12 month half-life. The recipes below were last verified on 2026-05-08; they may be stale by the time you read this. Before applying any pattern in this skill, fan out research scoped to the OWASP Top 10:2025 categories being audited so the recipes are interpreted against current authoritative sources, not against this file's snapshot.
8
9	### Default-on, with a documented skip
10
11	Run the 4-angle research below by default. Skip ONLY when ALL of these hold:
12
13	- (a) You ran this same skill on this same primitive within the last 4 hours of the current session,
14	- (b) That prior research surfaced no urgent advisories for the OWASP Top 10:2025 categories being audited,
15	- (c) You log a one-line `Research skipped because <reason>` note in your response.
16
17	"I think I know" / "moving fast" / "user wants this done quickly" / "already familiar" are NOT valid skip reasons. The whole point of this preamble is that future-you should not trust this skill body's defaults until current state is checked.
18
19	### Fan out 4 subagents in parallel
20
21	Each subagent returns ≤300 words of bullets with citations. Dispatch all 4 in a single message so they run concurrently.
22
23	Angle 1 — Authoritative standards. Have NIST / OWASP / IETF (RFCs and Internet-Drafts) / W3C / CISA published anything new about the OWASP Top 10:2025 categories being audited in the last 6-12 months? Look for: spec finalizations, deprecations, replacement specs, RFC publications, draft revisions, NIST SP updates, OWASP project version bumps. Cite by document number + publication date.
24
25	Angle 2 — Active exploitation. What's actively being exploited that targets the OWASP Top 10:2025 categories being audited? Pull from: CISA Known Exploited Vulnerabilities (KEV) catalog (filter to last 6-12 months), recent CVE / GHSA entries with high CVSS or in-the-wild exploitation, breach postmortems and incident reports (CSRB, vendor RCAs, security-vendor research). Surface CWE patterns dominating recent KEV adds. Cite by CVE number + advisory URL.
26
27	Angle 3 — Tooling and library state. Are the libraries this skill recommends still current? What are the latest major versions in the relevant package registry (npm / PyPI / RubyGems / crates.io)? Have any been deprecated, replaced, or merged into another project? Have any flipped a secure default? Look up current versions in: registry.npmjs.org, pypi.org, rubygems.org, crates.io, pkg.go.dev. Cite by package + version + release date.
28
29	Angle 4 — Practitioner discourse. What are practitioners and security teams talking about in the last 6 months? Pull from: OWASP Cheat Sheet Series (last-modified date matters), GitHub Security Lab posts, vendor security blogs (Cloudflare, Fastly, Snyk, Datadog, Wiz, GitGuardian), conference talks (Black Hat, DEF CON, OWASP Global AppSec, USENIX Security), SANS ISC, Krebs, recent OWASP project re-releases. Surface the patterns being adopted and the anti-patterns being called out. Cite by post URL + author + date.
30
31	### Synthesize before applying recipes
32
33	After the 4 returns land, write a 1-paragraph "current state for the OWASP Top 10:2025 categories being audited, as of <today's date>" that names:
34
35	- The current normative ceiling (what specs say SHOULD be the default in 2026).
36	- 1-2 active threats specific to the OWASP Top 10:2025 categories being audited from the last 6-12 months.
37	- Any tooling drift (deprecated lib, new default in a framework, package merged or replaced).
38	- Any practitioner consensus shift visible in recent cheat sheet / blog updates.
39
40	If the synthesis flags drift in this skill body's recipes (e.g., a spec finalized after 2026-05-08, a library now deprecated, a default flipped), call that out explicitly in your response and override the skill body where they conflict. The synthesis wins. The skill body is scaffolding, not scripture.
41
42	### When you cannot run subagents
43
44	If subagents are not available in your run
