secure-review

secure-review is a skill for Claude Code 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.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high System Prompt Leakage · line 9
    Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.
    Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
  • medium Excessive Agency · line 4
    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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 1mo 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 2mo ago), licensed MIT. It adds 35 tokens to every session and 4,767 once invoked, about $0.0001 per session on Opus 5.5. 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.
