secure

secure is a command for Claude Code from dinhnguyenngoc/spec-driven-claude-code. It costs 13 tokens per session (4,165 once invoked), scanned A, original, MIT.

A pre-development security review that examines a planned system using STRIDE, a method for categorizing threats such as impersonation, data changes, and information leaks.

In plain words
What is it for?
Use it to review an architecture, security requirements, permission rules, and OWASP Top 10 concerns before implementation.
Why use it?
It finds design-level security risks before code is written and turns them into requirements and safeguards. Code scanning and dependency checks are handled elsewhere.

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

secure 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 3d 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/secure — Pre-Development Security Review

"Security by design, not afterthought."

Purpose

Review architecture for security concerns BEFORE writing any code. Identify threats, define security requirements, and establish controls upfront.

Workspace Mode: if the session root declares Mode: workspace → resolve the target repo per CLAUDE.md §Workspace Mode before anything else; every path, probe, and gate below is relative to the target repo, and the workspace disk-check applies at the gate.

Scope

This command is DESIGN-LEVEL threat modeling — no code exists yet.

  • ✅ STRIDE on architecture, ADR review, security requirements, OWASP Top 10 compliance check
  • ❌ NOT: code scanning, dependency audit, SAST, secret-grep — those belong to /scan (post-development)

If a finding requires reading source code to confirm, defer it to /scan.

Prerequisites

Input files (must exist before /secure starts):

  • specs/SPEC.md — for asset inventory, data sensitivity, NFRs, and the Permission Matrix (the business authz basis for IDOR / Elevation-of-Privilege threats — the downstream contract spec.md §Permission Matrix declares)
  • architecture/ARCHITECTURE.md + its Open Questions section
  • architecture/adr/*.md — every ADR is a design decision with security implications; read them all (brownfield delta: read the ADRs touching the delta surface — see §Brownfield Mode)
  • plans/plan.md — for mitigation → task ID mapping (Phase 3). Required for a per-change run only; a whole-system baseline run (brownfield, no active change-set) legitimately has no plan yet and uses evidence ids / Backlog owners instead — see §Brownfield Mode → Baseline run.
  • .claude/rules/security.md — non-negotiables

Boilerplate templates (fixed — the agent fills in data, does not re-author structure):

  • .claude/templates/STRIDE_TEMPLATE.md — Asset inventory, STRIDE reference, Risk matrix, Threat block, Highest-Risk Surface table, THREAT_MODEL skeleton
  • .claude/templates/OWASP_TEMPLATE.md — OWASP Top 10 (2021) 10-row table, Security Requirements 6-domain checklist, Residual Risks table

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.

secure is a command published in the GitHub repository dinhnguyenngoc/spec-driven-claude-code (20 stars, last pushed 5d ago), licensed MIT. It adds 13 tokens to every session and 4,165 once invoked, about $0.0001 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 2026-08-30.
