secure-review

secure-review is a skill for Claude Code, Codex from backspace-shmackspace/claude-devkit. It costs 35 tokens per session (4,767 once invoked), scanned A, original, MIT.

A security review process for examining code changes by tracing data flows, checking trust boundaries, and reviewing authentication and access-control logic.

In plain words
What is it for?
It is used to review uncommitted changes, pull-request differences, or an entire codebase and produce a security report with a final status.
Why use it?
It helps find security problems and personal-data exposure that ordinary code review may miss, while separating findings from code fixes.

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-review 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 4d 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.

Expected in a hook, worth knowing in a rule or an instructions file.

How it starts

The opening of the file, as written. The whole thing — 442 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/secure-review Workflow

Output Rules

  • Always print full absolute paths for all artifact references (plan files, review files, audit logs). This makes paths clickable in terminals like Warp. Use the resolved $PLANS_DIR value, never relative paths.

Role

This skill is a scan coordinator. It orchestrates parallel semantic security scans across three dimensions — vulnerability patterns, data flow and PII exposure, and authentication/authorization logic — then synthesizes findings into a structured security report with a PASS / PASS_WITH_NOTES / BLOCKED verdict. It does not fix issues; it identifies and categorizes them.

This skill is a composable building block. When deployed, /audit can dispatch it as its security scan component for deeper analysis.

Inputs

  • Scope: $ARGUMENTS (optional)
    • changes — Uncommitted changes only (default)
    • pr — Pull request diff
    • full — Entire codebase

Step 0 — Determine scope and check for security-analyst agent

Resolve devkit paths (MUST be first action in Step 0):

Tool: Bash

# --- Devkit Path Resolution ---
DEVKIT_SCRIPTS="${CLAUDE_DEVKIT:-$HOME/.claude-devkit}/scripts"

# Source path resolution helper
if [ -f "$DEVKIT_SCRIPTS/resolve-project-dir.sh" ]; then
  . "$DEVKIT_SCRIPTS/resolve-project-dir.sh"
  DEVKIT_PROJECT_DIR_RESOLVED=$(resolve_devkit_project_dir) || {
    echo "Failed to resolve project directory" >&2; exit 1
  }
elif [ -n "${DEVKIT_PROJECT_DIR:-}" ]; then
  DEVKIT_PROJECT_DIR_RESOLVED="$DEVKIT_PROJECT_DIR"
else
  echo "WARNING: devkit is not installed. Using deprecated .devkit/ fallback." >&2
  DEVKIT_PROJECT_DIR_RESOLVED=".devkit"
fi

PLANS_DIR="$DEVKIT_PROJECT_DIR_RESOLVED/plans"
mkdir -p "$PLANS_DIR"
echo "Plans directory: $PLANS_DIR"

Tool: Bash, Glob

Scope resolution:

  • If $ARGUMENTS is empty: scope = changes
  • Else: scope = $ARGUMENTS

Validate scope is one of: changes, pr, full. If not, stop with: "Invalid scope. Use: /secure-review [changes|pr|full]"

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-review is a skill published in the GitHub repository backspace-shmackspace/claude-devkit (15 stars, last pushed 10d ago), licensed MIT. It adds 35 tokens to every session and 4,767 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
