security-review

security-review is a skill for Claude Code from sageox/ox. It costs 151 tokens per session (1,411 once invoked), scanned A, original, MIT.

A six-phase security review workflow for checking code changes against the main branch, the primary shared version of the code.

In plain words
What is it for?
It reviews command-line input, secret handling, daemon communication, software dependencies, and how the code trusts AI-generated content.
Why use it?
It organizes different security checks and removes duplicate findings when a review is run again.

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

security-review 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 6d 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.

/security-review — ox AI security pipeline

You are orchestrating a Synthesia-style 6-phase security review over the user's diff against origin/main. The pipeline shape, the dedup-before-validate ordering, and the right-size-models-per-phase principle all come from that post; the ox specifics (threat model, CLI/daemon primitives, hunter perspective frames) are local.

Trigger phrases

  • /security-review (no args) — review the diff vs origin/main. Default.
  • /security-review --scope=<path-glob> — narrow to a specific path.
  • /security-review --hunter=<name> — run only one hunter (debug). Valid names: cli-input, secrets-redaction, daemon-ipc, supply-chain, llm-trust.
  • /security-review --rerun — re-run on the same diff, dedupe against the previous run's findings.
  • /security-review --cap=<usd> — raise the per-run cost cap (default $2; persisted in security/config.yml).

What you do

You are not the pipeline. You are the dispatcher. You shell out to security/scripts/orchestrate.sh and surface its output to the user concisely. The pipeline runs the AI subagents itself; do not try to re-implement them in this skill body.

bash security/scripts/orchestrate.sh "$@"

The orchestrator drives all six phases:

  1. Prep — compute scope (diff vs origin/main, language mix, touched packages), write security/.output/scope.md.
  2. Map — run security/scripts/deterministic.sh (parallel OSS scanners) + spawn the Cartographer subagent (Haiku) to draw the call graph from entry points (CLI commands, daemon IPC handlers) to sinks. Writes security/.output/surface.md.
  3. Hunt — spawn 5 hunter subagents in parallel (Sonnet). Each has an explicit perspective frame (cli-input / secrets-redaction / daemon-ipc / supply-chain / llm-trust) to fight finding convergence. Writes security/.output/findings-raw.jsonl.
  4. Dedup — single Sonnet pass merges hunter findings + deterministic findings by root cause. Writes security/.output/findings-deduped.jsonl.
  5. Validate — one call per finding, model split: Sonnet for ~90%, Opus for the hard classes (secrets-redaction-bypass, daemon-ipc-authz-bypass, supply-chain-tampering). Stricter than hunters; traces real call paths; checks existing mitigations.
  6. Aggregate — drop false-positives, rank by severity, emit security/.output/FINDINGS.md (markdown) + security/.output/findings.sarif (machine).

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-review is a skill published in the GitHub repository sageox/ox (51 stars, last pushed today), licensed MIT. It adds 151 tokens to every session and 1,411 once invoked, about $0.0008 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.
