What is security-audit?

A review of web or native-app security, covering login permissions, input checks, record access, responses, secrets, headers, and platform protections.

It helps audit API routes, middleware, database access policies, environment settings, dependencies, and native permissions, then record findings in a refactoring backlog.

It looks for ways users could access data or actions they should not, expose secrets, send unsafe input, or weaken the app's security.

security-audit — Skill for Claude Code by marcoguillermaz

Install

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.

Any agent

npx skills add marcoguillermaz/Tierward --skill security-audit

Clone the repo

git clone --depth 1 https://github.com/marcoguillermaz/Tierward

Made for: Claude Code.

Or install tierward, the plugin that ships this one along with the rest of its 29 skills, 1 command, 1 hook, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.05151
Opus 5	$0.00000	$0.02576
Sonnet 5	$0.00000	$0.01030
Haiku 4.5	$0.00000	$0.00515

Security

Grade A, and why

security-audit scanned grade A with 1 finding 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**Live check** (staging): curl the staging URL and compare actual headers received vs configuration. A header present in config but absent in the response indicates a misconfiguration.

How it starts

The opening of the file, as written. The whole thing — 381 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Configuration (adapt before first run)

Replace these placeholders:

[SITEMAP_OR_ROUTE_LIST] - file listing all API routes with method, path, roles, and grouping - e.g. docs/sitemap.md, docs/routes.md. If not configured, the skill discovers routes by scanning the project's route handler directories. Announce the discovered routes before proceeding.

Scope: API routes, middleware/proxy, row-level access control policies, data validation, response shapes, environment variables, database configuration, dependencies. For native stacks: secrets management, platform security (Keychain/Keystore/entitlements), input validation, signing credentials, sensitive data protection. Out of scope: SEO, robots.txt, public crawlability, OpenGraph, sitemap.xml. Do NOT make code changes. Audit only. All findings are persisted to docs/refactoring-backlog.md via the backlog write-once protocol (.claude/rules/backlog-protocol.md).

Applicability check

Before any other step: read CLAUDE.md and check the Framework and Language fields.

Web or API project (Framework is NOT N/A - native app, OR route handler directories exist): proceed to Step 0 - full web audit (Steps 0–5) + Step 3e if the language is non-JS.
Native with API (Framework is N/A - native app AND route handler directories exist): proceed to Step 0 - full web audit (Steps 0–5) + Step 3e (native checks run in addition to web checks).
Native only (Framework is N/A - native app AND no route handler directories): skip Steps 0–5. Proceed directly to Step 3e (native-only audit). Then skip to Step 6 for the report.

Announce the execution path: Running security-audit - mode: [WEB | WEB+NATIVE | NATIVE-ONLY]

Step 0 - Target resolution

Parse $ARGUMENTS for a target: token.

Pattern	Meaning
`target:role:admin`	Focus on admin routes
`target:section:export`	Focus on all export/bulk-data routes
`target:section:<other>`	Read `[SITEMAP_OR_ROUTE_LIST]` - find rows matching the section keyword, resolve to API routes and related route files
No argument	Full audit - all API routes

Files

What ships with it

2 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.

Changes

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.

security-audit is a skill published in the GitHub repository marcoguillermaz/Tierward (4 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,151 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
